State of the art

The rapid development of electronic technology has allowed the use of various types of display devices in many areas. Research and development are focused on next-generation display devices, for example, a transparent display device. A transparent display device is a device that has transparency, so that the background behind the device can be seen through the device. Corresponding display panels are made using opaque semiconductor compositions such as silicon (Si) or gallium arsenide (GaAs). However, with the growing demand for various display services that cannot be realized with the appropriate display panels, efforts are being made to develop new types of electronic elements. A transparent display device was developed through one of these efforts.

The transparent display device includes a semiconductor layer of transparent oxide, and thus has transparency. When using a transparent display device, the user can observe information through the screen of a transparent display device, looking at the background located on the back side of the device. This allows you to remove restrictions on the size and time that may have the appropriate display devices. Since a transparent display device displays various information with the help of display units having transparency, real shapes of objects visible through the back side are harmonized with the displayed information. Thus, as user needs become more diverse, a new technology is required to provide information in more advanced ways using a transparent display device in various environments.

The above information is presented as historical information only to assist in understanding the present disclosure. No definition is made, and no statement is made as to whether any of the foregoing can be applied as a prior art with respect to the present disclosure.

In FIG. 1 is a block diagram of a transparent display device according to an embodiment of the present disclosure.

According to FIG. 1, a transparent display device 100 includes a display 110 and a controller 120. The display 110 includes a plurality of transparent display layers 110-1 ~ 110-n. Each of the transparent display layers 110-1 ~ 110-n can individually display information. In addition, since the transparent display layers 110-1 ~ 110-n are transparent, accordingly, the background of the transparent display device 100 can be seen even if multiple layers overlap. A detailed composition of the transparent display layers 110-1 ~ 110-n will be specifically described in a later part of the description of the invention.

The controller 120 may accordingly display various types of screens by controlling each of the transparent display layers 110-1 ~ 110-n. In particular, the controller 120 may display a first screen on a first transparent display layer, which is one of a plurality of transparent display layers, and may display a second screen on a second transparent display layer, which is another of a plurality of transparent display layers, when a first event occurs.

In this case, the first screen and the second screen may have independent sources. For example, playback screens relating to various multimedia contents can accordingly be provided as the first and second screens. Alternatively, the playback screens of applications that are different from each other, respectively, can provide both the first and second screens.

Furthermore, when a second event occurs, the controller 120 may change the transparent display layers when the first or second screen is displayed. In particular, when a second event occurs, the controller 120 may display the first screen that was displayed on the first transparent display layer on the second transparent display layer for a predetermined time. In contrast, the controller 120 may display a second screen that was displayed on the second transparent display layer on the first transparent display layer for a predetermined time. In addition, the controller 120 may convert the relative positions of the transparent display layers in which the first screen and the second screen are displayed. Such an operation of the controller 120 may vary according to the type of the second event.

It is assumed that the first transparent display layer is a transparent display layer arranged according to the direction in which the user is looking relative to the transparent display device, and that the second transparent display layer is a transparent display layer arranged back to the direction for ease of explanation. For example, when two transparent display layers 110-1, 110-2 are disposed, the top layer may be a first transparent display layer 110-1, and the bottom layer may be a second transparent display layer 110-2. However, this is just one embodiment of the present disclosure, and the controller 120 may first display the first screen on the lower layer and then the second screen on the upper layer when a particular event occurs.

The first screen or the second screen can be implemented in different ways, and can be a screen for reproducing images, texts, icons or content, an application implementation screen, a web browser screen, or screens of other graphic objects. As a result, when the user looks at one side of the transparent display device 100, he can fully see the screens displayed on each of the transparent display layers 110-1 ~ 110-n with a background. The number of transparent display layers 110-1 ~ 110-n can be implemented in different ways according to the type of device, the size of the device, and the user's environment. For convenience of explanation, the following is an explanation of the method for displaying screens on two transparent display layers 110-1, 110-2.

FIG. 2 shows that screens are respectively displayed on two transparent display layers 110-1, 110-2 according to an embodiment of the present disclosure.

According to FIG. 2, the first screen 10 is displayed on the first transparent display layer 110-1, and the second screen 20 is displayed on the second transparent display layer 110-2. Thus, when the user looks at the front side, he can see the first screen 10 and the second screen 20 with the background. Since the layers in which the first and second screens 10, 20 are displayed are different from each other, the user can feel the perspective between the first and second screens 10, 20. Thus, the perspective can be felt more naturally, and the user can feel 3-dimensional (3D ) view or perspective of a 2-dimensional (2D) display.

In addition, when the controller 120 generates the first and second screens 10, 20 with homogeneous images, for example, arrows, and then displays them according to the time interval, effects can be obtained to spatially direct the user's paths. Screens to be displayed on each of the first and second transparent display layers 110-1, 110-2 may be provided from external devices. Thus, the controller 120 of the transparent display device 100 may receive various screen data from an external server, memory, personal computer (PC), content player, or any other similar and / or suitable external source, and can display screen data through the first and second transparent layers 110 -1, 110-2 display. Moreover, such screen data may be internally generated and displayed by the transparent display device 100. When the transparent display device 100 generates screen data internally, the controller 120 may provide screens to be displayed on each of the first and second transparent display layers 110-1, 110-2 using frame buffers that are different from each other.

In FIG. 3 is a block diagram explaining a composition of a transparent display device according to an embodiment, the image processing of which is carried out by himself according to an embodiment of the present disclosure.

According to FIG. 3, the transparent display device 100 includes a display 110, which includes the first and second transparent display layers 110-1, 110-2, a controller 120, an image processor 130, and a storage 140. Programs, such as an operating room, may be stored in the storage 140. system (OS) and various applications and various data, for example, user settings data, data generated by the implementation of applications, and multimedia content. The controller 120 controls the image processor 130 using programs and / or data stored in the storage 140. The image processor 130 generates and provides screens to be displayed on the first and second transparent display layers 110-1, 110-2 according to the control of the controller 120. The processor 130 The image includes first and second display processors 131, 134, first and second frame buffers 132, 135, and first and second display drivers 133, 136.

The first and second display processors 131, 134 respectively generate screen data by processing the signal under the control of the controller 120. The first and second display processors 131, 124 can respectively install a calculation unit (not shown) and a visualization unit (not shown). The calculation unit calculates the characteristic values, for example, the coordinate value, shape, size and color, and these screen objects will be marked according to predetermined schemes. The visualization unit generates screen data of various schemes, which include objects, based on the characteristic values calculated by the calculation unit. The screen data generated in the first display processor 131 is stored in the first frame buffer 132, and the screen data generated in the second display processor 134 is stored in the second frame buffer 135. Such screen data may be generated and stored, for example, in a bitmap image format.

The first display driver 133 converts the screen data stored in the first frame buffer 132 into signals of the first image source and sends them to the first transparent display layer 110-1. The second display driver 136 converts the screen data stored in the second frame buffer 135 into the signals of the second image source and sends them to the second transparent display layer 110-2. The signals of the first and second image sources include scanning signals and excitation signals that are supplied to the electrodes connected to the respective cells, which make up the first and second transparent display layers 110-1, 110-2. Thus, the first and second transparent display layers 110-1, 110-2 can display the first and second screens, as shown in FIG. 2.

The transparent display layer can be implemented as various types of displays, for example, a transparent liquid crystal display (LCD), a transparent thin film electroluminescent (TFEL) display, and a transparent organo-LED (OLED) display or any other similar and / or suitable type of display.

The transparent LCD may represent a transparent display device implemented by removing backlight units from the currently used LCD device and using a pair of polarized light panels, an optical film, a transparent thin film transistor, and a transparent electrode. In a transparent LCD device, transmittance is reduced compared to polarized light panels or optical film, and light efficiency is reduced because ambient light emissions are used instead of backlight units; however, a transparent LCD device has the advantage that a transparent collision display can be realized.

A transparent TFEL display may be a device that uses an inorganic TFEL display (AC-TFEL) of the current type, which is formed by a transparent electrode, an inorganic luminescent and insulating layer.

AC-TFEL can be a display that emits light due to the inorganic luminescent excitation simultaneously with the acceleration of electrons to pass through the internal paths of the inorganic luminescent. When each transparent display layer is implemented as a transparent TFEL, the controller 120 may determine the position of the information labeling by adjusting so that the electrons can pass through the correct positions. Since the inorganic luminescent and insulating layer have transparency, it is possible to realize a display having extremely high transparency.

A transparent OLED display may be a transparent display device using OLEDs that themselves can emit light. Since the organic emitting layer is transparent when both electrodes are used as transparent electrodes, the organic emitting layer can be implemented as a transparent display device. OLED generates light by projecting electrons and holes on both sides of the organic emitting layer, so that they are combined with the organic emitting layer. A transparent OLED device displays information using this principle, i.e. by projecting electrons and holes in the requested positions.

In FIG. 4 and 5 are views illustrating various embodiments regarding a detailed composition of a display that includes a plurality of transparent display layers according to an embodiment of the present disclosure.

According to FIG. 4, an example composition in which transparent display layers implemented as a type of transparent OLED are sequentially integrated in a uniform direction. For convenience of explanation, FIG. 4 shows that two transparent display layers 110-1, 110-2 are integrated. First, the first transparent display layer 110-1 includes a transparent panel 111-1, a transparent transistor layer 112-1, a first transparent electrode 113-1, a transparent organic light-emitting layer 114-1, a second transparent electrode 115-1, a connecting electrode 116-1 and conductive layers 117-1, 118-1. The second transparent display layer 110-2 includes a transparent panel 111-2, a transparent transistor layer 112-2, a first transparent electrode 113-2, a transparent organic light-emitting layer 114-2, a second transparent electrode 115-2, a connecting electrode 116-2 and conductive layers 117-2, 118-2.

The first and second transparent display layers 110-1, 110-2 are connected to each other, where the second transparent electrode 115-2 of the second transparent display layer 110-2 has a surface that is adjacent to the surface of the transparent panel 111-1 of the first transparent layer 110-1 display. Thus, when the first transparent display layer 110-1 and the second transparent display layer 110-2 are vertically connected to each other, the first transparent display layer 110-1 in the upper position can be defined as the upper layer, and the second transparent display layer 110-2 in The bottom position can be defined as the bottom layer.

According to FIG. 4, the first and second transparent display layers 110-1, 110-2 may have a uniform composition. The detailed composition and operation of the first transparent display layer 110-1 will be specifically described below. For the transparent panel 111-1, a polymeric material having transparency, for example, plastic, glass or any suitable material, can be used. The materials of the transparent panel 111-1 can be determined according to the user's environment where the transparent display device 100 is used. For example, since the polymer material has the advantage of lightness and flexibility, it can be used in mobile display devices. Glass can be used in shop windows or ordinary windows.

The transparent transistor layer 112-2 may be a layer that includes transistors made by replacing the opaque silicon of the corresponding thin film transistor with transparent materials, for example, zinc oxides, titanium oxide, or any other suitable transparent material. A source, a gate, and conductive layers 117-1, 118-1 are installed in the transparent transistor layer 112-2, and a connecting electrode 116-1 can be installed that electrically connects the drain and the first transparent electrode 143-1. Although FIG. 4 shows one transparent transistor formed by a source, a gate, and a drain; many transparent transistors are included, evenly distributed over the entire surface area of the display during implementation.

The controller 120 can scan cells that include transparent transistors by supplying the above-described image source signals to the source, gate, and drain of each transistor in the transparent transistor 112-1 and can display different screens by turning on the corresponding cells. In particular, the first transparent electrode 113-1 and the second transparent electrode 115-1 are arranged in opposite directions based on the transparent organic emitting layer 114-1. The first transparent electrode, the transparent organic emitting layer, and the second transparent electrode 113-1, 114-1, 115-1 form transparent organic LEDs.

Transparent organic LEDs are divided into passive matrix OLED (PMOLED) and active matrix OLED (AMOLED) according to the excitation methods. PMOLED is a structure in which pixels are formed at the intersection areas of the first and second transparent electrodes 113-1, 115-1. At the same time, AMOLED is a structure where thin-film transistors (TFTs) are placed that excite each pixel. FIG. 4 demonstrates AMOLED.

The first transparent electrode 113-1 and the second transparent electrode 115-1, respectively, form a plurality of linear electrodes, and the placement directions of the linear electrodes are formed vertically with each other. For example, when the linear electrodes of the first transparent electrode 113-1 are arranged horizontally, the linear electrodes of the second transparent electrode 115-1 are arranged vertically. Thus, between the first transparent electrode 113-1 and the second transparent electrode 115-1, a plurality of intersection areas are formed. In each intersection region, a transparent transistor is connected, as shown in FIG. 4.

The controller 120 generates a potential difference in each intersection region using a transparent transistor. In the intersection region in which the electric potential difference, electrons and holes are formed, the project from each electrode to the transparent organic emitting layer 114-1 is combined with each other and thus emits light. Moreover, in the intersection region, where the electric potential difference is not formed, light emission is not carried out. Thus, the background is transparent and clearly visible.

Indium tin oxide (ITO) can be used for the first and second transparent electrodes 113-1, 115-1, however, embodiments of the present disclosure are not limited to this, and any suitable and / or similar material can be used. For example, you can use new materials, such as graphene. Graphene may be a material in which carbon atoms are connected to each other, forming a flat structure in the shape of a bee hive, which provides transparency. The transparent organic light emitting layer 114-1 can be implemented using various materials.

In addition, the controller 120 can control the display of screens on the second transparent display layer 110-2 using transparent transistors in the second transparent display layer 110-2. As a result, the first and second transparent display layers 110-1, 110-2, respectively, display screens.

If the first and second transparent display layers 110-1, 110-2 are arranged in a uniform direction, as shown in FIG. 4, when the controller 120 displays screens having uniform pixel values in uniform coordinates with respect to the first and second transparent display layers 110-1, 110-2, the placement directions of the first and second screens are the same. Thus, when the user looks at the front side, he can see that the first and second screens are displayed. Moreover, although FIG. 4 shows that the first and second transparent display layers 110-1, 110-2 are arranged in a uniform direction, the first and second transparent display layers 110-1, 110-2 can be arranged in opposite directions.

FIG. 5 shows that the first and second transparent display layers 110-1, 110-2 are sequentially integrated in opposite directions according to an embodiment of the present disclosure.

According to FIG. 5, the transparent panel 111-1 in the first transparent display layer 110-1 and the transparent panel 111-2 in the second transparent display layer 110-2 are attached to each other.

If the first and second transparent display layers 110-1, 110-2 are arranged as shown in FIG. 5, when the controller 120 displays screens having uniform pixel values in uniform coordinates with respect to the first and second transparent display layers 110-1, 110-2, the placement directions of the first and second screens are opposite to each other. In other words, when the user looks at the front side, it can be seen that the first screen is displayed, at the same time, it can be seen that the second screen is horizontally reversible. To observe the second screen, the user must flip the transparent display device 100 or go to the back side of the transparent display device 100.

According to FIG. 4 and 5, a plurality of transparent display layers are sequentially arranged in uniform directions or opposite directions. However, this is just one of various embodiments, and the arrangement of transparent display layers can be set in different ways. Thus, the plurality of transparent display layers can be parallel to each other or slide, partially overlapping each other.

FIG. 6 shows an example of a method for confirming screens displayed on a plurality of transparent display layers in a transparent display device according to an embodiment of the present disclosure.

FIG. 6 is provided for explaining a method according to which a user confirms screens displayed on each of the transparent display layers 110-1, 110-2 in a transparent display device 100 implemented as a mobile device according to an embodiment of the present disclosure.

As shown in FIG. 6, the first screen 10 is displayed on the first transparent display layer 110-1, which is located on the front side of the transparent display device 100, when the first event occurs, and the second screen 20 is displayed on the second transparent display layer 110-2, which is located on the back side. Moreover, the first event can be various events, for example, an event in which the user touches the first transparent display layer 110-1 or the second transparent display layer 110-2, an event for entering a command for implementing additional applications, an event for entering a command for playing an additional content, an event to achieve a previously stored set time, an event for generating system information messages, or any other similar and / or suitable event.

For example, when the user touches the first screen 10 when the first screen 10 is displayed, the controller 120 may generate a second screen 20 associated with the first screen 10 and display the second screen 20 on the second transparent display layer 110-2. The second screen 20, which is associated with the first screen 10, may be a screen provided from sources that are associated with objects marked in the first screen 10, or may be a screen that implements applications corresponding to the icons marked on the first screen 10. Event for entering a command to implement additional applications indicates the presence of user touches, button manipulation or remote control manipulation to implement additional applications other than those already implemented x applications, when the first screen 10 is a screen that displays the results of the implementation of applications. In addition, an event for inputting a command for reproducing additional content indicates the presence of user touches, button manipulation, or manipulation of a remote control to play content other than that displayed on the first screen 10 when the first screen 10 is a screen that displays the playback results of the still images or video content. An event to achieve a previously stored set time indicates a situation in which the set time is reached, which is a display condition from the display conditions that the user sets and saves for the second screen 20. For example, when it is set to constantly display the second screen 20, the second screen 20 may be displayed continuously . When set to display for one minute every hour, the second screen 20 can be displayed for one minute at the beginning of each hour. An event for generating system information messages indicates a situation in which various applications are updated, a situation in which mail, a messaging service and messages are received, a situation in which access to previously saved schedule information occurs, a situation in which a warning signal comes in, a situation in which the time comes for the issuance of various information messages, for example, system error messages and messages about the remaining battery power, and any other analogues GOVERNMENTAL and / or a suitable message. Thus, the second screen 20 can be displayed in various formats at different points in time according to the options for implementation.

As shown in FIG. 6, the system information message is displayed as a second screen 20 in a popup window format on the second transparent display layer 110-2 when the first screen 10 is displayed. As described above, the system information message may relate to various types of messages. When the second screen 20 is displayed on the second transparent display layer 110-2, the user who is observing the front side sees the back surface of the second screen 20. Thus, the user confirms the back side by turning the device as shown in FIG. 6. When the device rotates, the second screen 20 on the rear side of the device is seen as being displayed, and the rear surface of the first screen 10 is observed. Thus, the first and second screens can be displayed on different layers, which allows the user to easily confirm the screens. In this case, the user can control the operation by performing tactile manipulation on the first and second transparent display layers 110-1, 110-2.

In FIG. 7 is a view for explaining a method for recognizing touches in opposite directions and operating in a transparent display device according to an embodiment of the present disclosure.

According to FIG. 7, the transparent display device 100 includes first and second transparent display layers 110-1, 110-2. On the first and second transparent display layers 110-1, 110-2, touch sensors are respectively arranged.

In particular, from the plurality of transparent display layers, a first touch sensor 150-1 that senses a user's touch to a first transparent display layer 110-1 that is located in a first direction and a second touch sensor 150-2 that senses a user's touch may be further included. to the second transparent display layer 110-2, which is located in a second direction opposite to the first direction.

The first and second touch sensors 150-1, 150-2, respectively, can be implemented as a touch sensor with capacitive or resistive registration, or they can relate to any suitable and / or similar type of touch sensor. Capacitive registration is a way of calculating touch coordinates by registering a microelectric signal excited by the user’s body when parts of the user’s body touch the surface of the display layer with a dielectric deposited on the surface of the display layer. Resistive registration is a method that includes two electrode plates and calculates touch coordinates by registering electric currents by touching the upper and lower plates at the touch point when the user touches the screen. Thus, the touch sensor can be implemented in various formats.

The controller 120 may determine the types of tactile manipulation based on the registration signals recorded in the first and second touch sensors 150-1, 150-2. Since the first and second touch sensors 150-1, 150-2 are located on both of the two transparent display layers 110-1, 110-2, they can respectively register the touch of different bodies OB1, OB2 of the user. Tactile manipulation can be various manipulations, for example, simple touch, poke, touch and hold, move, easy swing, drag and drop, squeeze gesture and stretch gesture, or any other similar and / or suitable manipulations and touches.

The controller 120 may, accordingly, control the operation of the transparent display layers 110-1, 110-2 according to user touches registered in the first touch sensor 150-1 or the second touch sensor 150-2. In particular, the controller can move the display positions of the first screen 10 and the second screen 20 according to user touches, close the display situation, and further display new additional screens. In addition, if the first screen 10 or the second screen 20 displays icons or menu buttons for implementing specific functions, the controller 120 may display a screen corresponding to the function by implementing the corresponding function by touching the screen.

As a result, the transparent display device 100 may provide various screens using a plurality of transparent display layers 110-1, 110-2 ~ 110-n. The transparent display device 100 can be implemented in the form of various display devices, for example, a cell phone, tablet PC, laptop computer, monitor, TV, display case, electronic frame, e-book, MP3 player, PDA kiosk and any other similar and / or suitable display device or an electronic device including a display device.

In FIG. 8 is a view for explaining a method for performing a content reproduction operation in a transparent display device that includes a plurality of transparent display layers according to an embodiment of the present disclosure.

According to FIG. 8, the first screen 10 is a content playback screen that reproduces and displays content. When the content is selected and the playback command is entered, the controller 120 analyzes, decodes, and scales with respect to the selected content and displays on the first transparent display layer 110-1.

At the beginning of the reproduction of the content, the controller 120 may generate an information screen, which includes various information related to the content, as the second screen 20 and display the information screen on the second transparent display layer 110-2. For example, the second screen 20 may be a screen that displays various information of signs relating to the reproduction of content on the first screen 10, for example, size, type, resolution and time of reproduction, information of the degree of reproduction of the content, which shows at what point the content is reproduced, if the content is a video, various menus related to the manipulation of reproduction of content, information of previous content, information of the following content, list of contents, and any other analogue Other and / or suitable information.

Since the second screen 20 is observed when observing the first screen 10, the user can confirm the information of the second screen 20 and check various information regarding the contents by observing the first screen 10, as shown in FIG. 8. If necessary, the user can adjust the second screen 20 to be displayed on the front side by mutually converting or switching the layer on which the first screen 10 is displayed with the layer on which the second screen 20 is displayed. Such an operation will be described in a later part description of the invention. Although FIG. 8 shows a transparent display device implemented in a portable computer format, the operations shown in FIG. 8 can also be implemented in a uniform manner in other various types of transparent display devices.

In FIG. 9 is a view for explaining a method for performing an application loading operation in a transparent display device that includes a plurality of transparent display layers according to an embodiment of the present disclosure.

According to FIG. 9, the content may also include program content, for example, applications other than various multimedia content, for example, still image content, video content, audio content, and 3D content. As shown in FIG. 9, when a user command for loading content is entered, the transparent display device 100 generates a download implementation screen for implementing content loading as the first screen 10 and displays the first screen 10 on the first transparent display layer 110-1.

The controller 120 of the transparent display device 100 may process the page data transmitted from the server that provides the content, and may generate a download implementation screen. The user can enter a command to implement the download regarding content by tapping (T) on the first screen 10. When the download implementation command is entered on the download implementation screen, the controller 120 accesses the server and requests the download of the corresponding content.

Thus, when the download starts, the controller 120 generates a loading situation display screen that marks at least one of the degree of loading processing of the selected content, the estimated closing time, content indication information and content source information, as the second screen 20 and displays it on a second transparent display layer 110-2.

As shown in FIG. 9, when the first and second transparent display layers 110-1, 110-2 respectively display different screens 10, 20, a single screen that is combined with two screens 10, 20 can be recognized from the user's point of view, as shown in FIG. 9. Thus, the recognition of performance can be improved by recognizing information loading content, otherwise than on the previous screen 10.

Although FIG. 9 shows an implementation of a transparent display device in the form of a cell phone, such operations shown in FIG. 9 can be implemented in a uniform manner in various other types of transparent display devices and electronic devices.

FIG. 8 and 9 illustrate that the second screen 20 automatically marks information associated with the first screen. However, the second screen 20 can be generated differently according to the situation of the device differently than on the first screen 10. For example, the second screen 20 can be implemented as an additional information screen, which includes at least one of the remaining battery power, communication status, time information, system information, volume information, network connection information, setup information, date information, weather information, text message reception status information, missed call information and any other similar and / or suitable information.

In FIG. 10 is a view for explaining the operation of a transparent display device used in a display case according to an embodiment of the present disclosure.

According to FIG. 10, a transparent display device includes first and second transparent window format display layers 110-1, 110-2 that are arranged in series. Thus, as shown in FIG. 10, the first and second screens 10, 20, respectively, displayed on the first and second transparent display layers 110-1, 110-2 and real shapes of objects 30 that are located in the rear region of the transparent display device 100 are fully visible to the user.

The first and second screens 10, 20 can be displayed at a closer distance when installing related descriptions. For example, the first screen 10 can be displayed as specific text, and the second screen 20 can be displayed in the form of an arrow around the first screen 10. Thus, the user can intuitively recognize that the product indicated by the text of the first screen 10 is located in the direction of the arrow of the second screen 20.

As described above, the first screen 10 and the second screen 20 can be displayed on different display layers 110-1, 110-2 in various formats and at different positions. The transparent display layers displayed on the first screen 10 and the second screen 20 can be mutually transformed into each other according to user manipulation.

In the above-described embodiments, the transparent display device can adjust the display features of each screen individually according to the information of the surrounding situation. The information of the surrounding situation may be the intensity of the ambient lighting, the weather, the current time, the number of surrounding objects and any other similar and / or suitable information. In addition, the display features may be transparency, color, size, display position, display time, display shape and resolution. For example, in the daytime, the controller 120 marks the colors of the first and second screens 10, 20 with thick initial colors to increase recognition performance.

In addition, the controller 120 may accordingly adjust the resolution of screens displayed on various transparent display layers to determine focus. When the resolution of the screen displayed on the third layer (not shown) is adjusted to increase clarity while adjusting the resolution of screens displayed on other layers to reduce clarity, the screen on the third layer can be recognized most quickly by the user. The controller 120 may determine the focus in relation to each layer according to the activation situation of each application. For example, when the word implementation window displayed on the third layer is activated, the resolution of the implementation window is distinct, while other screens are not clearly displayed. Thus, the display features of each screen can be adjusted differently according to the situation.

In addition, the controller 120 may adjust the resolution of each screen according to the position of the user. The transparent display device 100 may further include a sensor (not shown) for detecting a user's position. The sensor may be implemented as a motion sensor, an infrared (IR) sensor, or any similar and / or suitable sensor. The controller 120 of the transparent display device 100 may determine which transparent display layer is closer to the user from the plurality of transparent display layers using such a sensor. The controller 120 may adjust the display features of screens displayed on each of the transparent display layers according to the determination results. For example, the controller 120 may set the resolution of the screen displayed on the rear transparent display layer to be higher than the resolution of the screen displayed on the transparent display layer in the direction of the user’s position. Thus, screens displayed at an increased distance can be clearly recognized by the user. In addition, when implemented, the controller 120 may prevent recognition performance from deteriorating due to distance difference by increasing the size of the rear screen and to provide perspective by adjusting the brightness of each screen according to the distance from the user.

In FIG. 11 and 12 are views illustrating an operation of converting layers to each other, in which a plurality of screens are displayed according to an embodiment of the present disclosure.

When the first and second screens 10, 20 are displayed on different transparent display layers, when a second event occurs, the controller 120 of the transparent display device 100 may display one of the first and second screens 10, 20 on different transparent display layers for a predetermined time or may change All layers display two screens. FIG. 11 shows that the transparent display layer on which the first screen 10 and the second screen 20 are displayed are mutually transformed when a second event occurs.

According to FIG. 11, the first transparent display layer 110-1 may display the first screen 10, and the second transparent display layer 110-2 may display the second screen 20. For ease of presentation, the first and second screens 10, 20 are shown as illustrating A and B, however, the present embodiment the implementation is not limited to this, and the first and second screens 10, 20 can be implemented in various formats described above and display or demonstrate any suitable content. When a second event occurs in the aforementioned situation, the first screen 10 is moved and displayed on the second transparent display layer 110-2, and the second screen 20 is moved and displayed on the first transparent display layer 110-1, as shown in FIG. eleven.

In this case, the second event may be various events. For example, the second event may include at least one of an event for making a long touch, an event for making a double touch, an event for making a touch and drag, an event for making a light swing, an event for reaching a predetermined change time, and an event for generating new informational messages. A long touch may be a user action involving touching the front transparent display layer beyond a predetermined time, and a double touch may be a user action involving touching twice in a row. Touching and dragging can be a user action involving moving the touch point while touching the surface of the layer, and a light swing can be a user action involving quickly moving the touch point one way while touching the surface of the layer.

Although FIG. 11 describes an embodiment in which the first and second transparent display layers 110-1, 110-2 are included, layer conversion can be performed for any suitable number of transparent display layers. For example, with respect to a transparent display device 100 including first, second, and third transparent display layers 110-1, 110-2, 110-3 (see FIG. 16), when a screen conversion command is entered once by touching the first a transparent display layer 110-1 on the front side, while the first, second, and third screens 10, 20, 30 are displayed in layers, respectively, the first screen 10 is moved and displayed to the second transparent display layer 110-2, the second screen 20 moves and displays to the third transparent display layer 110-3, and the third screen 30 is displayed and moves to the first transparent layer 110-1 display. When the screen conversion command is entered again, the display layers of the first, second, and third screens 10, 20, 30 can be changed in a uniform pattern.

In addition, in the transparent display device 100 including the first, second, third and fourth transparent display layers 110-1, 110-2, 110-3, 110-4, the first screen 10 may be displayed on the first transparent layer 110-1 display, and the second screen 20 may be displayed on the third transparent display layer 110-3. If a command for converting the screen is entered, the second screen 20 is moved and displayed on the first transparent display layer 110-1, and the first screen 10 is moved and displayed on the third transparent display layer 110-3. Thus, screens can be moved and displayed between a plurality of transparent display layers according to predetermined patterns.

In FIG. 12 is an example of an operation that converts and uses screen display layers. First, the content screen ‘A’ is displayed on the first transparent display layer of the display layers of the screen of the first screen 10, and the content list is displayed on the second transparent display layer as the second screen 20.

When the user touches (T) the first screen 10, the layers that display the first screen 10 and the second screen 20 mutually transform. Thus, a second screen 20 including a list of contents is displayed on the front surface. The user can select the content as desired from the content list. As shown in FIG. 12, if the user touches (T) ‘B’ in the content menu, then the transparent display device 100 closes the playback of the contents of ‘A’ and plays the contents of ‘B’. By this operation, as shown in FIG. 12, the transparent display device 100 moves the second screen 20 to the second transparent display layer on the back side and displays the content ‘B’ as the first screen 10 on the first transparent display layer 110-1.

Moreover, as shown in FIG. 12, when the first and second screens 10, 20 are displayed in positions corresponding to each other in different layers, the user may have difficulty recognizing the first screen and the second screen separately, since the two screens overlap. Thus, the transparent display device 100 may adjust the display features of the first screen differently than the display features of the second screen. In this case, the display features may be transparency, color, size, display position, display time, display shape and resolution. The transparent display device 100 can adjust the display features of each screen and display so that the user can recognize that the rear screen is being generated without introducing visual disturbances into the user's observation. For example, if the front screen is displayed in thick colors, while the back screen is displayed in relatively soft colors, the user recognizes the colors of the overlapping parts, the back screen being different from the surrounding colors, and intuitively observes that another screen is generated on the back side, without interfering with the front view screen.

Although FIG. 12 describes an embodiment in which display layers of two screens are alternately transformed according to a user selection, a display layer of each screen can be sequentially transformed at the user's choice.

In FIG. 13 is a view for explaining a page conversion operation using a plurality of transparent display layers according to an embodiment of the present disclosure.

According to FIG. 13, the transparent display device 100 implements a function according to a user selection and displays screens. In this process, if the screen to be displayed is constituted by a plurality of pages, one page of them is first displayed. In FIG. 13, for convenience of explanation, the first display screen is illustrated as the first page screen 1300-1. The layer displaying the first page screen 1300-1 may vary according to user setting values or default values, however, FIG. 13 shows that the first page screen 1300-1 is displayed on the first transparent display layer 110-1 on the front side.

In this situation, when the user performs the first user touch manipulation (T) at one point on the first page screen 1300-1 and drags in the direction, the transparent display device 100 displays the next page, i.e. a second page screen 1300-2 on the first transparent display layer 110-1 according to the drag direction and a first page screen 1300-1 on the second transparent display layer 110-2, as shown in FIG. 13. When the first user manipulation is sequentially performed in this situation, according to the direction of the drag, the third page screen 1300-3 and the fourth page screen 1300-4 are sequentially displayed on the first transparent display layer 110-1, and the second page screen 1300-2 and the screen 1300 -3 of the third page that were previously displayed are shifted and displayed on the second transparent display layer 110-2, as shown in FIG. thirteen.

Thus, the user can transform the page screens using the first user manipulation. Moreover, as shown in FIG. 13, when the second user manipulation in which the user makes a long touch (T) on the screen during the display of the fourth page screen 1300-4, the third page screen 1300-3 that is displayed on the second transparent display layer 110-2 is moved and displayed on the first transparent display layer 110-1, and the fourth page screen 1300-4 that is displayed on the first transparent display layer 110-1 is moved and displayed on the second transparent display layer 110-2, as shown in FIG. 13. When the first user manipulation is performed again in this situation, the page conversion is performed again in the direction of the drag. The fourth page screen 1300-4 is displayed on the first transparent display layer 110-1, and the fifth page screen 1300-5 is displayed on the second transparent display layer 110-2, as shown in FIG. thirteen.

Although FIG. 13 shows two types of user manipulation, types of user manipulation can be implemented in different ways. In this case, the display positions of screens displayed on the plurality of transparent display layers 110-1, 110-2 may overlap with each other. In this case, the transparent display device 100 may adjust various display features, for example, color, resolution, size, display time, font, and clarity of two screens so that two screens are recognized as one screen.

In FIG. 14 is a view illustrating an operation of generating one screen by combining screens displayed on a plurality of transparent display layers according to an embodiment of the present disclosure.

According to FIG. 14, the first screen 10 displayed on the first transparent display device 110-1 is displayed as text, and the second screen 20 displayed on the second transparent display device 110-2 is displayed in the form of a rear window. The rear window can be expressed in opaque colors so that objects located on the rear side are not clearly visible through the first screen 10 and do not interfere with its observation. For example, if the text of the first screen 10 is yellow, the second screen 20 may be the only window in black. In this case, since the user recognizes that the text of the first screen 10 is recorded on the second screen 20, the recognition performance can be improved. Thus, the transparent display device 100 can provide various screen formats by appropriately combining the display features of each screen.

In FIG. 15 is a view for explaining an embodiment that provides feedback effects according to user touches according to an embodiment of the present disclosure.

According to FIG. 15, when the user touches the touch point (T) of the first transparent display layer 110-1 on the front side, while the first and second transparent display layers 110-1, 110-2 are arranged in series, feedback effects 40 corresponding to user touches in the area, the corresponding touch point on the second transparent display layer 110-2 are displayed on the back side. Feedback effects can be a graphic for visual notification of a touch. For example, a color image may be displayed within a predetermined radius based on the touch point (T), or an image describing that something is exploding can be displayed, as shown in FIG. 15. Such feedback effects 40 can be noted immediately when touched, and disappear gradually or quickly. Moreover, although the above descriptions are based on a transparent display device 100 including two transparent display layers, the transparent display layers can be implemented in an amount greater than three, or any suitable amount, as described above.

In FIG. 16A and 16B are views illustrating an operation of converting layers whose screens will be labeled from a plurality of transparent display layers according to an embodiment of the present disclosure.

According to FIG. 16A and 16B, the transparent display device 100 includes a number n of transparent display layers 110-1 ~ 110-n. The controller 120 of the transparent display device 100 displays the first screen 1600 on the first transparent display layer 110-1 according to user input. The first screen 1600 includes a plurality of objects 1610, 1620. Moreover, the objects can be of various types, for example, an image, a picture, text, a pop-up window, a banner window, a media playback window, or any other similar and suitable object for display. The user may touch one object in the first screen 1600 or touch a point where objects are not marked in the first screen 1600. FIG. 16A shows a case of touching one object 1610 in a first screen 1600.

The controller 120 moves and displays the touch object 1610 to another transparent display layer located below the first transparent display layer 110-1. The depth of the transparent display layer where the object moves can be determined according to the signs of user touch. Signs of user touches may include user touch pressure, touch time, touch speed, number of touches, and any other similar and / or suitable feature. According to FIG. 16B, the touch object 1610 is moved and displayed from the first transparent display layer 110-1 to the third transparent display layer 110-3. If the touch is performed with increased pressure, the object can move to a layer located below the third transparent display layer 110-3. Thus, objects 1610, 1620 displayed in one screen 1600 can be distributed and displayed in other transparent display layers according to a user selection.

Moreover, by touching the point where the objects are not marked in the first screen 1600, the entire first screen 1600 can be moved and displayed in a transparent display layer having a depth corresponding to the signs of user touches.

Thus, with respect to each screen or each object, the display layers can be transformed according to a custom selection. To convert display layers, the controller 120 may use a frame buffer. For example, when the transparent display device 100 is implemented in the format of FIG. 3, if it is requested to move the screen displayed on the first transparent display layer 110-1 to the second transparent display layer 110-2, then the controller 120 copies the data stored in the first frame buffer 132 to the second frame buffer 135. The controller 120 may control a second display driver 136 to deliver data copied to a second frame buffer 135 to a second transparent display layer 110-2. In the case of requesting separation of some of the objects displayed on the same screen, the controller 120 may retrieve the objects to be divided by reading data stored in the first frame buffer 132, or using data input to the first display processor 131. The second display processor 134 may process data regarding the extracted objects to be divided, may generate image data regarding the corresponding objects, and may store them in a second frame buffer 135. Thus, the divided objects can be displayed on the second transparent display layer 110-2.

Moreover, if the screens displayed on different transparent display layers, respectively, deliver value when the positions of the screens overlap, the rear screen may be obscured by the front screen. In this case, as described in FIG. 11, the screen display layers can be transformed according to user manipulation, and the back screen can be observed. However, according to another embodiment, it can also be understood that the rear screen can be observed by changing the shape, size and / or position of the front screen.

FIG. 17 is a view for explaining a screen conversion operation, while the plurality of transparent display layers respectively display screens according to an embodiment of the present disclosure.

On the left side of FIG. 17 shows the shapes of screens displayed, respectively, on the first and second transparent display layers 110-1, 110-2, and on the right side of FIG. 17, the entire display screens 110 are viewed from a user's point of view. According to FIG. 17A, when the first and second screens 10, 20 are displayed in a uniform position of the first and second transparent display layers 110-1, 110-2, respectively, the second screen 20 can be obscured by the first screen 10. Thus, from the point of view of the user, only the first screen 10 is observed as shown in FIG. 17.

When in this situation, the user touches one part of the first screen 10, the second screen 20 opens, while the shape of the first screen 10 changes. The shape of the first screen 10 may vary in different ways according to the points of touch. In the case of touching the upper point, the first screen 10 changes, as if its upper part slid back, and thus, the second screen 20 opens. The first screen 10 may save its change during a user touch and may return to its original state immediately after the user touch ceases. Alternatively, the first screen 10 may change within a predetermined time after the user touch, and then may return to its original state.

When in this situation the user touches the bottom point on the first screen 10, the first screen 10 changes as if its lower part was rolled back, and the second screen 20 opens, and thus, the second screen 20 is opened to the eyes of the user. In this way, the user can confirm each screen. Moreover, according to another embodiment, the display situation of each screen can be changed according to the rotation situation by registering the rotation of the transparent display device.

In FIG. 18 is a view illustrating a screen conversion operation when the transparent display device is rotated according to an embodiment of the present disclosure.

According to FIG. 18, the transparent display device 100 may further include a sensor (not shown) that senses a rotation situation of the transparent display device. The transparent display device 100 displays the first screen 10 on the first transparent display layer 110-1 and the second screen 20 on the second transparent display layer 110-2, and the user rotates the device 100 from right to left 180 °. When observing the screens 10, 20 from the rear side, a horizontally reversed display is recognized. When registering rotation, the controller 120 converts at least one of the first screen 10 and the second screen 20 horizontally or vertically in accordance with the situation of rotation and display. According to FIG. 18, screens 10, 20 are converted horizontally and displayed uniformly with observation on the front side prior to rotation.

FIG. 18 shows a conversion from right to left. However, the present embodiment is not limited to this, and if the rotation is from left to right or from top to bottom, the screen display situation can be reorganized to be suitable for the rotation situation, which allows the user to observe properly placed screens. At the same time, another screen is additionally displayed when observing one screen in the corresponding display device, and the user may be worried, since the visualization of the other screen takes longer. Thus, according to another embodiment, the transparent display device 100 can use a plurality of transparent display layers and process so that the user cannot notice a delay in the screen display process.

In FIG. 19 is a view for explaining a conversion operation of screens displayed on a plurality of transparent display layers according to an embodiment of the present disclosure.

According to FIG. 19, when an event for displaying the second screen 20 occurs when the first screen 10 is displayed on the first transparent display layer 110-1, the controller 120 of the transparent display device 100 starts rendering the second screen 20, as shown in FIG. 19. The second screen 20 is displayed on the second transparent display layer 110-2, which is located below the first transparent display layer 110-1. The second screen 20 is rendered at a position that is obscured by the first screen 10 from the entire area of the second transparent display layer 110-2, i.e. in the position corresponding to the first screen 10. Visualization can be done sequentially based on lines.

As shown in FIG. 19, the controller 120 continues to display the first screen 10 on the first transparent display layer 110-1 while the rendering of the second screen 20 is being processed. Thus, since the second screen 20 is obscured by the first screen 10, the user does not visually perceive a delay during the display process of the second screen 20. Upon completion of the visualization, the controller 120 removes the first screen 10 and opens the second screen 20 displayed on the second transparent display layer 110-2 . Thus, the second screen 20 is immediately displayed, although the visualization process is not observed by the user. Moreover, as described above, a transparent display device can be implemented as various types of devices.

In FIG. 20 is a view for explaining the operation of a transparent display device, which is implemented as a table display device according to an embodiment of the present disclosure.

According to FIG. 20, the transparent display device 100 is implemented as a table including a plate supporting a table and table legs. The display 110 is placed on a plate supporting the table. The display 110 includes a plurality of transparent display layers 110-1 ~ 110-n, as described above. The controller 120 displays screens 2010, 2020, 2030, 2040 on each of the layers 110-1 ~ 110-n. The controller 120 displays screens 2010, 2020, 2030, 2040 according to events when events occur. According to embodiments, the display methods of each screen can be implemented in different ways.

FIG. 20 shows an embodiment in which the controller 120 differently sets the display positions of screens 2020, 2030, 2040, which are displayed on lower layers taking into account connectivity with the first screen 2010, while the first screen 2010 is displayed on the first transparent display layer 110-2 which is the topmost layer.

For example, when the second screen 2020 associated with the first screen 2010 is displayed on the second transparent display layer 110-2, the second screen 2020 may be displayed partially overlapping with the first screen 2010, and the third and fourth screens 2030, 2040 that are not associated with the first screen 2010, can be displayed in positions that do not overlap with the first and second screens 2010, 2020. The second screen 2020, which is associated with the first screen 2010, indicates the screen associated with the objects selected on the first screen 2010, or the screen for the implementation of related applications or widgets . As for the parts overlapping with the upper screen, the color or sharpness can be set differently so that the user can intuitively recognize the overlap with the upper and lower screens.

Layers of the display screens 2010, 2020, 2030, 2040 can be converted in various ways according to your choice. These methods are previously described in the above various embodiments, which will not be further explained. In addition, events for displaying screens that are not explained are described above. Although FIG. 20 describes a transparent display device in a table format, a transparent display device can be implemented as various types of electronic devices used and used in various fields, for example, furniture, window, transparent door, frame, display case and wall and any other similar and / or suitable electronic devices.

In FIG. 21 is a block diagram illustrating the composition of a transparent display device according to various embodiments of the present disclosure.

According to FIG. 21, the transparent display device 100 includes a display 110, a controller 120, an image processor 130, a storage 140, a touch sensor 150, a communication unit 160, a global positioning system (GPS) receiver 171, a digital multimedia broadcast (DMB) receiver 172, sensors 180 -1 ~ 180-m motion detection from first to mth, audio processor 190, loudspeaker 191, button 192, universal serial bus (USB) port 193, camera 194 and microphone 195.

The display 110 includes a plurality of transparent display layers, and each transparent display layer displays screens by separately controlling the controller 120. The composition and operation of the display 110 are described in the aforementioned several embodiments, which will not be further explained.

The touch sensor 150 may detect tactile manipulation of the user using the touch sensor located on at least one layer of the plurality of transparent display layers. The touch sensor 150 may install a touch sensor located on the uppermost layer, or all touch sensors located on the uppermost layer and the lowest layer. A method for recording a touch using a touch sensor has been previously described in the descriptions of FIG. 7, which will not be further explained.

The plurality of motion detection sensors 180-1 ~ 180-m are sensors that can detect the rotation of the transparent display device 100 and the position of the user. In order for the sensor to detect rotation, you can use a geomagnetic sensor, an acceleration sensor and a gyro sensor. The acceleration sensor displays registration values corresponding to the acceleration of gravity, which varies according to gradient devices with an attached sensor. A gyro sensor is a sensor that detects angular velocity by measuring the Coriolis force applied in the direction of speed when rotational motion occurs. A geomagnetic sensor is a sensor that records azimuth. In order for the sensor to register a user's position, an infrared sensor and a photodiode can be used.

The controller 120 controls the image processor 130 to display different screens on each of the transparent display layers according to the registration results recorded by the touch sensor 150 and the plurality of motion detection sensors 180-1 ~ 180-m, button manipulation 192, user motion gestures received by the camera 194, and voice commands received with a 195 microphone.

The controller 120 may control each unit using programs and data stored in the storage 140. For example, the controller 120 may communicate with external devices through the communication unit 160. The communication unit 160 is a hardware unit that communicates with various types of external devices according to various types of communication methods. The communication unit 160 includes various communication chips, for example, a WiFi chip 161, a Bluetooth chip 162, a Near Field Communication (NFC) chip 163, and a wireless communication chip 164.

The WiFi chip 161, the Bluetooth chip 162, and the NFC chip 163 communicate, respectively, according to the WiFi method, the Bluetooth method, and the NFC method. The 163 NFC chip is a chip that operates according to the NFC method, which uses a 13.56 MHz band from various radio frequency identification (RF-ID) frequency bands, for example 135 kHz, 13.56 MHz, 433 MHz, 860 ~ 960 MHz and 2, 45 GHz. When a WiFi chip 161 or a Bluetooth chip 162 is used, various connection information, such as a service set identifier (SSID) and session key, may be transmitted and / or received first, communication may be using information, and various information may be transmitted and / or received.

Wireless communication chip 164 communicates according to various communication standards, for example, the Institute of Electrical and Electronics Engineers (IEEE), Zigbee, 3rd Generation (3G), the 3G Partnership Project (3GPP) and the Long-Term Development of Communication Systems (LTE) project. Controller 120 may display data received from external devices through communication unit 160 on each of the transparent display layers.

Meanwhile, the GPS receiver 171 is a unit that receives GPS signals from GPS satellites and measures the current position of the transparent display device 100. When implementing the navigation function, the controller 120 can calculate the current position using the GPS signals received by the GPS receiver 171, and can display a route screen that reflects the current position on one of the transparent display layers. In this case, the controller 120 may display a map screen on the lower layer and a route screen on the upper layer. In this way, the user can observe the navigation screen providing a sense of perspective.

The DMB receiver 172 is a hardware unit that receives and processes DMB signals. When implementing the DMB function, the controller 120 may display the DMB reception screen on one of the transparent display layers. If DMB signals are provided with scripts, controller 120 may separate scripts and display scripts and image frames on different display layers. For example, image frames may be displayed on the lower layer, and scripts may be displayed on the upper layer. In this way, the user can recognize scripts with a better sense of perspective.

The image processor 130 has the role of generating screens displayed on each of the transparent display layers 110-1 ~ 110-n, as described above. An image processor 130 may be formed as shown in FIG. 3. However, the image processor is not limited to this and can be implemented in any similar and / or suitable manner. The image processor 130 may optionally install various blocks, for example, a codec for encoding or decoding video data, an analyzer, a scaling unit, a noise filter, and a frame rate conversion module. In addition, the image processor 130 can be implemented to use one combined frame buffer, split the buffering area, and use the corresponding transparent display layers without using the frame buffers individually placed on each of the transparent display layers in FIG. 3.

The audio processor 190 is a hardware unit that processes audio data. The audio processor 190 may perform various processing, for example, decoding, amplification, and noise filtering, with respect to audio data. When playing content including audio data, the controller 120 may control the audio processor 190 to output audio signals while displaying a playback screen on one of the multiple transparent display layers. Audio signals are supplied to the loudspeaker 191 and output. If the diverse content is accordingly reproduced and displayed on different transparent display layers, then the controller 120 may control the audio processor 190 to process audio signals corresponding to the content displayed on the first transparent display layer, which is the uppermost layer.

The loudspeaker 191 is a hardware unit that outputs various warning sound signals and voice messages, as well as audio data processed on the audio processor 190. The button 192 may be various types of buttons, for example, a mechanical button, a touch panel, or a wheel formed in an area, for example , the front side, the partitioned side and the back side of the external body in the transparent display device 100. The USB port 193 can communicate with various external devices via USB cables. Camera 194 is a hardware unit that takes photographs or videos under the control of the user. Camera 194 may be implemented as a front side camera and a rear side camera. Microphone 195 is a hardware unit that receives user voices or other sounds and converts them into audio data. The controller 120 may use the voices of users entered through the microphone 195 when making a call, or may convert the voices of users into audio data and store them in the storage 140.

When the camera 194 and microphone 195 are turned on, the controller 120 may perform a control operation according to the voices of users inputted through the microphone 195 or the user movement recognized by the camera 194. The transparent display device 100 may operate in a motor control mode or a voice control mode, as well as Normal mode, which is controlled by user touch or button manipulation.

When operating in motor control mode, the controller 120 photographs the user by activating the camera 194, monitors changes in user movement and performs the corresponding control operation. When operating in the voice control mode, the controller 120 may operate in a voice recognition mode that analyzes user voices inputted through the microphone 195 and performs a control operation according to the analyzed user voices.

In addition, various external input ports can be additionally provided for connecting to various external components, such as a headset, mouse, and LAN. The above operation of the controller 120 may be carried out by programs stored in the storage 140. In the storage 140, OS software may be stored to drive a transparent display device 100, various applications, various data input or set when implementing applications, content, touch gestures, motion gestures, voice teams, and event information. The controller 120 controls the overall operation of the transparent display device 100 using various stored programs.

The controller 120 includes random access memory (RAM) 121, read-only memory (ROM) 122, a timer 123, a central processing unit (CPU) 124, interfaces 125-1 ~ 125-n from first to n-th and bus 126. RAM 121 , ROM 122, timer 123, main CPU 124, and first through n-th interfaces 125-1 ~ 125-n can be connected to each other via bus 126. First through n-th interfaces 125-1 ~ 125-n are connected with the various blocks described above. One of the interfaces may be a network interface that connects to external devices through a network. The main CPU 124 bootstraps by accessing the storage 140 and using the OS stored in the storage 140. In addition, the main CPU 124 performs various operations using various programs, contents and data stored in the storage 140.

ROM 122 stores command sets for booting the system. When a power-on command is applied and electric power is applied, the main CPU 124 copies the OS stored in the storage 140 to the RAM 121 according to the commands stored in the ROM 122, and loads the system through the implementation of the OS. When the boot is completed, the main CPU 124 copies the various application programs stored in the storage 140 to the RAM 121, and performs various operations by implementing the application programs copied to the RAM 121.

When various types of user manipulation are recorded by a plurality of motion detection sensors 180-1 ~ 180-m, a button 192, a camera 194, and a microphone 195, the main CPU 124 determines whether an event consistent with the event information stored in the store 140 occurs using the results registration. In addition, the main CPU 124 may determine whether an event occurs using the registration results recorded by other units. As described, an event can be set in various ways. For example, an event can be an event for making user touches or selecting a button, an event for entering motion gestures and voice commands, an event for entering a command for implementing applications, an event for entering a command for playing content, an event for reaching a predetermined time or a predetermined period, an event for generating system information messages, an event for communicating with external sources and any other similar and / or suitable event.

When an event occurs, the main CPU 124 downloads the programs corresponding to the event from the storage 140 in the RAM 121 and implements the programs. The main CPU 124 drives the image processor 130 according to the implementation of the programs and displays screens corresponding to the event.

While one screen, i.e. the first screen 10 is displayed on the first transparent display layer 110-1 when an event occurs to display another screen, i.e. of the second screen 20, the main CPU 124 determines a display layer that displays the second screen. In this case, the main CPU 124 may determine the display layer, taking into account the relationship with the first screen and the second screen, user setting information and screen size. Thus, when the first screen 10 and the second screen 20 are screens for displaying a uniform level of information, the main CPU 124 displays them on the same layer. For example, when the user again enters a command to implement a web browser, while the first screen 10 is a web browsing screen, the second screen 20 can be implemented as a web browsing screen and displayed on the same first transparent display layer. Moreover, when the user selects some of the objects in the first screen 10, while the first screen 10 is a web browsing screen, a web browsing screen coming from sources associated with the selected objects, i.e. the second screen 20 is displayed on a different layer than the first screen 10. Thus, when the first screen 10 is displayed on the upper layer, the first screen 10 can move to the lower layer, and the second screen 20 can be displayed on the upper layer again.

The main CPU 124 may determine a display layer for displaying the second screen 20 and determine the size or display position of the second screen 20 according to the user setting situation. Thus, when the user determines that the second screen 20 should not overlap with the first screen 10, the main CPU 124 can display the second screen 20 in a different position, while avoiding displaying the position of the first screen 10, and can determine its size or its shape so that it did not overlap with the first screen 10. As a result, the controller 120 may determine the display layer of each screen, the display position, and other display features.

When at least one of the motion detection sensors 180-1 ~ 180-m detects the rotation of the transparent display device 100, or when user touches are detected by the touch sensor 150, the main CPU 124 may transform the display layers of the screens or may change the display position and other features display according to rotation or touch. Such an operation is specifically described in the above various embodiments, which will not be further explained.

In this case, the main CPU 124 can count the time under the control of the timer 123. Thus, the main CPU 124 can determine whether there is a long touch by counting the time the user touches the situation, and adjust the display layers of the screen or other display features according to the determination results. In addition, whether an event occurs can be determined according to the countdown of the timer 123.

FIG. 21 fully illustrates various blocks in the case where the transparent display device 100 includes various functions, for example, a communication function, a broadcast reception function, a video playback function, and a display function. However, the present embodiment is not limited to this, and the transparent display device 100 may provide any suitable and / or similar function. Thus, according to embodiments, some of the blocks shown in FIG. 21, other blocks may be deleted or changed or re-added. Moreover, as described above, the controller 120 may perform various functions by implementing programs stored in the storage 140.

FIG. 22 shows a software architecture that is applicable to a transparent display device according to an embodiment of the present disclosure.

According to FIG. 22, software 140 may be stored in the storage 140, which includes a base module 141, a registration module 142, a communication module 143, a presentation module 144, a web browser module 145, and a service module 146.

In particular, the registration module 142 is a software module that performs the operation of extracting signs of manipulation, for example, the coordinates of where to touch, the direction of movement of the touch, the speed of movement and the distance of movement.

The main CPU 124 can extract a rotation situation, a user position and a touch point of the transparent display device 100 by implementing the registration unit 142 and analyzing the registration values recorded by the plurality of motion detection sensors. In addition, according to various embodiments, the registration module 142 may include a face recognition module, a voice recognition module, a motion recognition module, and an NFC recognition module.

Communication module 143 is a module that communicates with the environment. The communication module 143 may include a messaging module 143-1, for example, a messaging service program, a short message service (SMS) and a multimedia messaging service (MMS) program, and an email program and a calling module 143-2 installing a combining software module call information and voice over Internet Protocol (IP) (VoIP) module.

Presentation module 144 is a module that generates display screens. Presentation module 144 includes a multimedia module 144-1 for reproducing and outputting multimedia content and a user interface (UI) visualization module 144-2 for processing UI and graphics. The multimedia module 144-1 may include a player module, a video camera module, and a sound processing module. Thus, the multimedia module 144-1 reproduces various multimedia content by generating and reproducing screens and sounds. UI rendering module 144-2 may include an image compilation module that combines images, a coordinate combining module that combines and generates coordinate values on screens that display images, an X11 module that receives various events from the equipment, and a 2D toolbox / 3D UI, which provides tools for generating UIs in 2D or 3D.

When an event for displaying screens occurs, the main CPU 124 determines a transparent display layer in which screens are displayed after the screens are generated by implementing the presentation module 144. The main CPU 124 displays the respective screens on a transparent display layer. After that, when an event occurs for displaying other screens, the presentation module 144 determines a transparent display layer in which corresponding screens are displayed, and displays screens on a specific layer. In addition, the presentation module 144 may perform operations such as transforming a screen or changing a display situation.

The web browser module 145 is a module that accesses the web server by performing web browsing. The web browser module 145 may install various modules, for example, a web browsing module for generating web pages, a download agent module for downloading, a bookmark module, and a web bundle module.

Although FIG. 22 shows various program modules, some of the various illustrated program modules can be deleted or changed, or new modules can be added according to the types and features of the transparent display device 100.

In FIG. 23 is a flowchart for explaining a display method of a transparent display device according to various embodiments of the present disclosure.

According to FIG. 23, a transparent display device may include a plurality of transparent display layers that are integrated in series. When an event occurs in operation S2320 when the first screen 10 is displayed on the first transparent display layer 110-1 in operation S2310, the transparent display device displays a second screen 20 on the second transparent display layer 110-2 which is different from the layer on which the first screen 10 is displayed in operation S2330. The layer on which the first screen is displayed and the layer on which the second screen is displayed are mutually transformed according to the user command.

In FIG. 24 is a flowchart for explaining a display operation of a transparent display device according to various embodiments of the present disclosure.

According to FIG. 24, when a user enters a conversion command in operation S2420, while the first and second screens 10, 20, respectively, are displayed on different transparent display layers in operation S2410, the transparent display device 100 converts layers in which the first and second are respectively displayed second screens 10, 20, in operation S2430. In this case, the input of the conversion command is one of the described second events, and the conversion of the layers can be carried out according to various cases. In addition, the layer conversion in operation S2430 may include various subprocesses according to the options for implementation.

For example, when a second event occurs, it may be intended to display the first screen 10 displayed on the first transparent display layer 110-1 on the second transparent display layer 110-2 for a predetermined time. Furthermore, the layer conversion may include displaying a second screen 20 displayed on the second transparent display layer 110-2 on the first transparent display layer 110-1 for a predetermined time when the second event occurs, and all such detailed processes. Moreover, a certain time can mean the time until the end of the second event or a set time, for example, a predetermined base time (for example, five seconds). Screen types and screen conversion operations are described previously in the above-mentioned various embodiments, which will not be further explained.

Moreover, when rotation is detected in operation S2440, the transparent display device can accordingly swap the first screen 10 and the second screen 20 according to the rotation situation in operation S2450. At the same time, a swap indicates that the screens are flipped horizontally or vertically and displayed as shown in FIG. 18. As a result, a transparent display device may provide various UI formats using a plurality of transparent display layers. Thus, it is possible to increase the performance of screen recognition, and it is possible to provide a different sensation of screens, which increases user satisfaction. In addition, in the above various embodiments, for convenience of explanation, the first screen 10 is described as A and the second screen 20 is described as B, however, the first and second screens 10, 20 can be implemented in various formats. The following is an explanation of the various embodiments of each screen.

FIG. 25, 26, and 27 show examples of screens displayed on a plurality of transparent display layers according to an embodiment of the present disclosure.

According to FIG. 25, the first and second screens 10, 20 may be described with reference to specific embodiments of the screens, and may be referred to as various specific screens corresponding to particular embodiments. The first transparent display layer 110-1 displays a screen 10 for implementing a document writing program, and the second transparent display layer 110-2 displays a clipboard screen 20. If the user wants to capture specific expressions, tables and images when writing documents, he can carry out a predetermined tactile manipulation on the relevant parts. The controller 120 may copy or paste selected portions into the clipboard screen 20 according to tactile manipulation. For example, when a long touch manipulation is performed on specific objects, and when the copy command regarding the long touch manipulation is agreed upon, the corresponding objects can be displayed uniformly on the clipboard screen 20, while the objects on the implementation screen 10 are displayed as is. In addition, when a double-touch manipulation is performed on specific objects, and when an insert command is agreed on with respect to the double-touch manipulation, corresponding objects can be deleted from the implementation screen 10 and displayed on the clipboard screen 20.

The user can place the clipboard screen 20 on the front side and the implementation screen 10 on the back side by converting layers to display screens. For example, when a user manipulates touching and dragging in the same direction, layers for displaying screens are transformed. In the implementation, in this situation, of a predetermined manipulation on the objects displayed on the screen 20 of the clipboard, the corresponding objects can be moved and displayed again on the screen 10 of the implementation. When implementing a program for writing a document, the screen 20 of the clipboard can be automatically implemented due to the relationship with the program, or can be implemented selectively at the command of the user.

In FIG. 26, an embodiment is shown that displays an icon display screen and an implementation screen by selecting an icon, respectively, on different transparent display layers. The transparent display device 100 may display a background screen 10 that includes various icons in a normal standby situation. The background screen 10 can be displayed on the uppermost layer, which can directly record touches, i.e. the first transparent display layer 110-1. When one icon 2 receives a user touch (T) in this situation, the transparent display device 100 implements the application corresponding to the icon 2 and generates an implementation screen 20. At this point, the transparent display device 100 displays the implementation screen 20 on the first transparent display layer 110-1, while moving and displaying the background screen 10 previously displayed on the first transparent display layer 110-1 on the second transparent display layer 110-2. Thus, the transparent display device 100 can directly register that the user is touching the implementation screen 20. When the user finishes the implementation screen 20, the transparent display device 100 removes the implementation screen 20, again moves and displays the background screen 10 into the first transparent display layer 110-1. Although in FIG. Figure 26 shows the operation when selecting the application icon, a similar operation can be performed when selecting the folder icon or file icon. For example, when selecting a folder icon, a screen for marking a list of files stored in a folder can be immediately displayed on the first transparent display layer 110-1.

In FIG. 27, an embodiment is shown in which a setting screen is displayed allowing the user to set various functions in the transparent display device 100. When the user selects the function setting menu, the transparent display device 100 displays the implementation screen 10 on the first transparent display layer 110-1, and the quick view screen 20 according to the functions set on the implementation screen 10, on the second transparent display layer 110-2. As described above, since the image processing is carried out separately with respect to the first and second transparent display layers 110-1, 110-2, the display features of the quick view screen displayed on the second transparent display layer 110-2 can only change according to the setting values set on the screen 10 of the implementation, while maintaining the signs of the display screen 10 of the implementation, as in the initial state. For example, when a user adjusts various display features, such as color, resolution, size, and clarity, according to the implementation screen 10, the transparent display device 100 generates a quick view screen 20, applying the values changed on the implementation screen 10, and displays the screen on a second transparent layer 110- 2 displays. To observe the quick view screen 20 during the setup, the transparent display device 100 may place the position of the implementation screen 10 and the position of the quick view screen 20 without overlapping each other. In this way, the user can immediately confirm the changes to the quick view screen 20 while making adjustments through one display 110.

As a result, the corresponding screens displayed on transparent display layers can be implemented in different ways. Thus, as described above, image frames and scripts can be split and displayed on different transparent display layers, or the background screen and characters can be separated from one image frame and displayed on different transparent display layers, which provides a sense of perspective.

The screens displayed on the bottom layer can be various application pop-up information, for example, a notification about an incoming message, the number of unread messages, an email notification, the number of unread emails, call waiting time, call setup time, alert setting situation, warning duration, nap time, music play time, video play time, total number of lists, display updated Nia application, request the display to change the folder, display processing load and display the volume of free use. In addition, system pop-up information may be displayed to provide information about the remaining battery, volume, intensity at the antenna, and the local reception area.

In addition, the controller 120 may store various situations, for example, the type, stack, color and size of the screens displayed on the transparent display layer in the store 140, and may adjust the display features of the screens displayed on the lower transparent display layers according to the situations. For example, the controller 120 may control the generation of the lower screen with colors or text other than the colors or text of the upper screen, and may control the display of the lower screen at a position where the upper screen is not displayed, i.e. in a position that does not overlap with the top screen. Such operations are specifically described in the above various embodiments, which will not be further explained. In this case, in another embodiment, it is possible to provide, respectively, an individual task screen and a collective task screen using a transparent display.

In FIG. 28 is a block diagram of a transparent display device according to an embodiment of the present disclosure.

According to FIG. 28, the transparent display device 100 includes a transparent display 110, a controller 120, an image processor 130, a first sensor 150-1 and a second sensor 150-2. The transparent display 110 has the property of transparency, which allows you to see images through it. The transparent display 110 may be implemented in a flat shape. The first sensor 150-1 detects a touch entered into a first surface from two surfaces of the transparent display 110, and the second sensor 150-2 detects a touch entered into a second surface that is different from the first surface of the transparent display 110. The first and second sensors 150-1, 150-2 can be implemented as touch sensors.

The image processor 130 generates various screens under the control of the controller 130 and provides generated screens to the transparent display 110. In particular, the “individual task screen” means that one of the two surfaces of the transparent display 110 is a controlled screen, and the “collective task screen” means that both surfaces of the transparent display 110 are controllable. The individual screen, as well as the collective task screen, can refer to various types of screens, for example, an application execution screen, a web browser screen, a multimedia content playback screen, a thumbnail display screen, etc.

The controller 120 may display at least one of the individual and collective job screens on the transparent display 110 according to a user selection. When the individual task screen is displayed, the controller 120 controls the display of the individual task screen according to a touch inputted in the direction where the individual task screen is displayed. For example, when a document writing program is provided as an individual task screen, the controller 120 may display various texts and the like. on the screen of the individual task or edit the document in accordance with the touch entered into the surface of the two surfaces of the transparent display 110, which displays the screen of the individual task. Accordingly, the individual task screen is controlled by only one user.

On the contrary, when the document writing program is provided on the collective task screen, the controller 120 may display various texts on the collective task screen or may edit the documents according to a touch inputted on both surfaces of the transparent display 110. Thus, the first user is in the direction of the first surface and the second the user in the direction of the second surface, which are located opposite each other, and between them is a transparent display 110, are able to collectively control l the collective task screen by touching the screens. The individual task screen may include an opaque background area that impedes perception on the opposite side, and the collective task screen may include a transparent background region that facilitates perception on the opposite side.

FIG. 29 illustrates in detail individual and collective task screens according to an embodiment of the present disclosure.

According to FIG. 29, the individual display screen 2910 of the transparent display device is successfully perceived in the direction of the first surface, i.e. in the forward direction, while in the direction of the second surface, i.e. in the backward direction, it is only seen as an opaque background screen. As for the collective task screen 2920, which has a transparent background region, this screen can be perceived in the front and rear directions. The only difference in the rear view is that objects 2921, 2922 on the collective task screen 2920 exchange their positions on the left and right. For convenience of explanation, the screens shown in FIG. 29 have the same configuration and objects, with the exception of the difference between the background areas on the individual task screen and the collective task screen. To provide opaque and transparent areas of the background, the transparent display 110 may include two transparent display layers.

In FIG. 30 and 31 are views illustrating a method for displaying individual and collective task screens using two transparent display layers according to an embodiment of the present disclosure.

According to FIG. 30, the transparent display 110 includes first and second transparent display layers 110-1, 110-2 that are stacked sequentially on top of each other. As explained above, since the first and second transparent display layers 110-1, 110-2 have a transparency property, the background of the transparent display device 100 can be observed even if there are a plurality of layers stacked on top of each other. The composition of the transparent display 110 will not be explained again below, but will be based on the detailed explanation given above with reference to FIG. 3, 4 and 5.

When the individual task screen is displayed on the first transparent display layer 110-1, the controller 120 can control so that a specific area from all areas of the second transparent display layer 110-2 that corresponds to the individual task screen becomes opaque. When the second transparent display layer 110-2 includes a plurality of LCD pixels, the controller 120 may cause the region to become opaque by supplying an excitation voltage to the respective pixel blocks and thus blocking light penetration.

According to FIG. 31, the controller 1220 displays the screen on the first transparent display layer 110-1 and controls the second transparent display layer 110-2 so that it becomes transparent, and therefore, the screen displayed on the first transparent display layer 110-1 is perceived from both directions. When the first user enters a predetermined manipulation with respect to the collective task screen, the controller 120 may control the image processor 130 to swap the left and right sides of the collective task screen. For example, the left and right sides of the collective task screen can be swapped in response to a light swipe or drag of a user who touches the collective task screen and moves in a certain direction. As explained above, the first and second users, who are located opposite each other relative to the transparent display 110 located between them, are able, if necessary, to swap the left and right sides of the collective task screen, to align the text or image on the collective task screen in the direction suitable for observation.

On the contrary, when the second user enters a predetermined manipulation with respect to the collective task screen, the controller 120 may change the collective task screen to the individual task screen. For example, the screen may change to the individual task screen when the user performs a long touch manipulation on the collective task screen. FIG. 30 and 31 show an example where the entire screen is implemented as an individual or collective task screen. However, the individual or collective task screen may be partially displayed on the screen or displayed together in one screen. In this case, more than two transparent display layers may exist. For example, you can provide three transparent display layers.

In FIG. 32 is a view illustrating a method for displaying individual and collective job screens using three transparent display layers according to an embodiment of the present disclosure.

According to FIG. 32, the transparent display 110 may include first, second, and third display layers 110-1, 110-2, 110-3. The controller 120 may control a second transparent display layer 110-2, which is intermediate, so that it becomes transparent or opaque. In other words, the controller 120 can control the region (I) corresponding to the individual task screen so that it becomes opaque, while at the same time controlling the region (II) corresponding to the collective task screen so that it becomes transparent.

FIG. 32 specifically shows an example where the upper region (I) of the second transparent display layer 110-2 becomes opaque, while the lower region (II) becomes transparent. The controller 120 may display the first individual task screen 3210 in the upper region of the first transparent display layer 110-1, while at the same time displaying the collective task screen 3220 in the lower region. In addition, the second individual task screen 3230 may be displayed in the upper region of the third transparent display layer 110-3.

FIG. 32 also shows a screen that is perceived in the first direction of the transparent display 110. The first individual task screen 3210 having an opaque background region (I) and the collective task screen 3220 having a transparent background region (II) can be displayed together. A second individual task screen 3230 having an opaque background region (I) and a collective task screen 3220 having a transparent background region (II) can be displayed together in a second direction. The collective task screen 3220 perceived in the second direction is inverted relative to the collective task screen 3220 perceived in the first direction.

Accordingly, the first user in the first direction is able to use the first individual task screen 3210 and the collective task screen 3220, while the second user in the second direction is able to use the second individual task screen 3220 and the collective task screen. The controller 120 controls the first individual task screen 3210 in accordance with the first touch entered on the first surface, controls the second individual task screen 3230 in accordance with the second touch entered on the second surface, and controls the collective task screen 3220 in accordance with the first and second touches, entered in both directions.

Although FIG. 31 and 32 specifically demonstrate a method for constructing an individual task screen and a collective task screen using a plurality of transparent display layers; it is also possible to construct an individual task screen and a collective task screen using a single transparent display layer. In this case, each of the individual task screen and the collective task screen may be displayed in a transparent state. The controller 120 may control the individual task screen in accordance with a touch input in one direction, and control the collective task screen in accordance with a touch entered in both directions.

Controller 120 may selectively display individual and collective job screens in accordance with user manipulation. For example, when a predetermined event occurs in a state in which the individual task screen is displayed, the controller 120 may change the individual task screen to the collective task screen. The term ‘event’ as used here may include entering a predefined tactile manipulation of a user or selecting from a screen change menu.

In FIG. 33 is a view illustrating a method of changing between an individual task screen and a collective task screen according to an embodiment of the present disclosure.

FIG. 33 shows an individual task screen. The individual task screen has at least one object displayed in the region of an opaque background. On the individual task screen, you can add the menu 3310 screen change. When the user touches the menu 3310, as shown in FIG. 33, the controller 120 may change the individual task screen to the collective task screen as further shown below in FIG. 33. Alternatively, when the user touches the individual task screen and rotates it clockwise or counterclockwise, as shown in FIG. 33, the controller 120 may translate the background area of the individual task screen into a transparent state, change the individual task screen to a collective task screen, as further shown below in FIG. 33. In yet another embodiment, the user can control such that the collective task screen and the individual task screen are displayed together by dragging the individual task screen.

FIG. 34 and 35 are intended to explain a method for displaying a collective task screen on one side of an individual task screen according to an embodiment of the present disclosure.

According to FIG. 34, the individual task screen 3410 may display a scroll bar 3411. The user can touch and drag the scroll bar 3411. The controller 120 may move the individual task screen 3410 in response to the user dragging, while additionally displaying the collective task screen 3420 on one side of the individual task screen 3410. Although FIG. 34 shows an example where the scroll bar 3411 is displayed in the upper center region of the individual task screen 3410, according to which the collective task screen 3420 slides in a downward direction, the scroll bar 3411 may be arranged differently.

In FIG. 35, a situation is illustrated where the scroll bar 3411 is displayed in the center of the right edge of the individual job screen 3410. Accordingly, when the user touches the scroll bar 3411 and drags it to the left side, in response to such a drag, the collective task screen 3420 slides in the direction from the right edge to the left. In this case, with the exception of the situation when the entire screen of the individual task changes to the collective task screen, the transparent display device 100 can go to the collective task screen in the block of objects or areas.

In FIG. 36 is a view for explaining a method of inverting an object display on an individual task screen to a state perceived on the opposite side according to an embodiment of the present disclosure.

According to FIG. 36, the individual task screen 3600 may include a plurality of objects 3610, 3620. When a user whiskes one object 3610, the controller 120 controls the image processor 130 to rotate the smeared object 3610 to a state reversed with respect to the right / left side and displays it . In addition, the controller 120 processes the reversed object 3610 ’so that the object 3610’ is perceived on both sides. Accordingly, the user on the opposite side can correctly observe the object 3610.

In FIG. 37 is a view for explaining a method of inverting a display of a specific area of the individual task screen to a state perceived on the opposite side according to an embodiment of the present disclosure.

According to FIG. 37, when user-defined manipulation is entered to indicate a specific area on the individual task screen 3600, the controller 120 of the transparent display device 100 controls the image processor 130 to reverse the display state in the specific area. In addition, the controller 120 processes in such a way that the reversed area 3610 ’is perceived on both sides of the transparent display 110. The user can touch a specific area on the individual task screen 3600 and drag it to indicate the area. When the user touches the screen, a selection area 3700 is displayed with reference to a touch spot. The selection region 3700 changes size and shape as the touch spot moves. When the touch ceases when the user's hand is removed from the screen, the screen in the finally displayed selection area 3700 is turned.

In FIG. 38 is a view for explaining a method of inverting a full screen of an individual task to a state perceived on the opposite side according to an embodiment of the present disclosure.

According to FIG. 38, when a user enters a predetermined user manipulation on the individual task screen 3600, the individual task screen 3600 can fully rotate to a state facing the right / left side. Accordingly, the reversed screen 3600 ’is displayed.

Although FIG. 36-38 illustrate an example where an individual task screen changes to a collective task screen; embodiments are not limited to this. That is, it is equally possible to change the collective task screen to the individual task screen. When the collective task screen is displayed, the first user in the first direction and the second user in the second direction are able to control, if necessary, the display state of the task screen by reversing the display state. Accordingly, many users are able to jointly build a collective task screen.

In addition, screen attributes may be supported when display state is reversed. For example, when a predetermined user manipulation is entered into the individual task screen, access can occur in a block of the screen, areas or objects, as explained above. Accordingly, the first user can show the result of his work to the second user on the opposite side, and then return the screen back to the first user. In this case, the transparent display device 100 is capable of changing direction when the screen is displayed according to the user's position.

In FIG. 39 is a view for explaining a method of changing a direction of a display screen according to an embodiment of the present disclosure.

According to FIG. 39, the transparent display device may include a user sensor 3910. The user sensor 3910 may include various types of sensors, for example, an ultrasonic sensor, an infrared sensor, or any suitable and / or similar type of sensor. You can also implement a camera. In the case of the implementation of the camera, the sensor 3910 user can determine the presence and / or absence of the user by analyzing the photographic image. When registering a user position by means of a user sensor 3910, the controller 120 displays an individual task screen or a collective task screen in the direction where the user position is recorded.

In a state where the individual task screen 3900 is displayed in the first direction, when the user is registered in the second direction, the controller 120 reverses the individual task screen 3900 in the second direction, the user is oriented. Accordingly, the user is able to perceive the screen without reference to the right / left side in any direction. Although FIG. 39 shows an example where the direction of the display screen is reversed depending on the position of the user, the controller 120 may change the screen based on recognition of the user's eyes.

In FIG. 40 is a view illustrating a method for moving an object on an individual task screen to a collective task screen and displaying it on it according to an embodiment of the present disclosure.

According to FIG. 40, the transparent display device 100 displays a collective task screen 4020 on one side of the individual task screen 4010. The user can move objects on the respective screens 4010, 4020. FIG. 40 specifically shows an example where an object 4011 displayed on an individual task screen 4010 is moved to a collective task screen 4020. When entering user manipulation, touching and moving the object 4011 to the collective task screen 4020, the controller 120 displays the object 4012, which is identical to the selected object 4011, on the collective task screen 4020, and displays the object 4012 in a state facing the right / left side. Accordingly, the selected object 4012 is displayed on the screen of the collective task 4200 with the possibility of perception on both sides of the transparent display 110.

In FIG. 41 is a view illustrating a method for changing an object displayed on an individual task screen to a state perceived on the opposite side, according to an embodiment of the present disclosure.

According to FIG. 41, the left side of FIG. 41 shows the front side 4100-1 of the individual screen, while the right side of FIG. 41 shows a front side 4100-2 of an individual task screen. Object 4110 is displayed on the front side 4100-1 of the individual task screen. When the user long presses the object 4110, as shown on the left side of FIG. 41, the pressed object 4110 goes to the collective task screen. Accordingly, the pressed object 4110 disappears from the front side 4100-1 of the individual task screen and appears on the rear side 4100-2, as shown on the right side of FIG. 41. As explained above, the user is able to control the operation of the transparent display device 100 through various interactions.

In FIG. 42 is a flowchart for explaining a display method of a transparent display device according to embodiments of the present disclosure.

When an event for displaying a collective task screen occurs in operation S4230, a collective task screen is displayed in operation S4240, various types of events can be implemented. For example, the individual task screen can be completely replaced by the collective task screen when a predefined user manipulation is entered on the individual task screen, or when a selection event from the screen change menu occurs.

Alternatively, the transparent display device 100 may further display a collective task screen on one side of the individual task screen when a drag event on one side of the individual task screen occurs. Further, when user manipulation is entered in a block of objects, areas or screens, as explained with reference to FIG. 36, 37, and 38, some objects, areas, or the entire screen may change to the attributes of the collective task screen according to such a manipulation.

In operation S4250, the transparent display device 100 collectively controls the collective task screen in accordance with the first and second touches when the collective task screen is displayed. Using the collective task screen, many users are able to carry out the task together with each other.
