Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the accompanying drawings. In the following description of the present invention, a detailed description of known functions and configurations incorporated herein will be omitted when it may make the subject matter of the present invention rather unclear. The following terms are defined in consideration of the functions of the present invention, and may vary depending on users, operators, customs, and the like. Therefore, the definition should be based on the contents throughout this specification.

Figure 1 is a diagram illustrating a display system 1000, in accordance with an embodiment of the present invention. As shown in FIG. 1, the display system 1000 includes a display device 100 and a remote control device 200. The display device 100 may be a smart TV, but it may be realized by various display devices such as a projection TV, a monitor, a notebook PC, a tablet, and the like. Although the remote control device 200 is illustrated as being implemented by a smart remote controller, it may be realized by various devices such as a pointing device, a motion recognition device, a voice recognition device, and the like,

For example, when the user turns off the power of the display device 100 and the user turns on the remote control device 200, the remote control device 200 senses the movement of the user. The remote control device 200 transmits the sensed motion information to the display device 100. Upon receiving the motion information, the display device 100 displays the UI element. For example, as shown in FIG. 1, a UI element may be a UI element that provides time information. When the power on command is received from the remote control device 200 while the UI element is displayed, the display device 100 displays the image content.

Through the display system 1000, the user can obtain the real time information through the UI element displayed on the display device 100 only by lifting the remote control device 200. In addition, the user may be provided with the image content suitable for the situation of the user through the UI element. Therefore, the user can obtain the user experience even before viewing the video content.

Also, in order to display an immediate UI element like the display system 1000 according to an embodiment of the present invention, it is required to turn on the power within a short time. In the case of the display system 1000 according to the embodiment of the present invention, the UI element can be displayed on the display device 100 when an average of 1 to 1.5 seconds elapses from the operation of lifting the remote control device 200. [

The display device 100 supports the SRPO (Suspend to RAM Power Off) state when the power is turned off, and the memory wakeup address and the system power supply required at the next boot time before entering the SRPO state according to an embodiment of the present invention. Off state to the sub-processor MICOM and stores it. The memory wakeup address may be the kernel wakeup vector value of the operating system to be executed first after the re-memory among the memory addresses storing the previous operation state of the system. The display device 100 can execute the fast boot sequence in the subsequent power-on process using the stored information. Accordingly, when the remote control device 200 is operated, the display device 100 can display UI elements instantly using the stored memory wakeup address.

In addition, the display device 100 may determine whether the stored information is abnormal and resume or cold boot. The term " resume " means to return from the suspended state to the power-on state, and the " cold boot " means that the power is turned on again after the display apparatus 100 is completely powered off.

In addition, the communication module, the camera module, and the like connected through the USB may be sequentially resumed after resuming the other components of the display device 100, thereby improving the booting speed.

As shown in FIG. 1, the operation of lifting the remote control device 200 or providing the time information in the display device 100 is only one embodiment, and is not limited thereto. Hereinafter, various embodiments of the display apparatus 100 and the remote control apparatus 200 will be described.

2 is a block diagram briefly showing a configuration of the display device 100. As shown in FIG. Referring to FIG. 2, the display device 100 includes a display unit 110 and a control unit 120.

The display unit 110 displays image contents input from various sources under the control of the controller 120. [ Also, the display unit 110 displays pre-registered UI elements.

The control unit 120 controls the overall function of the display device 100. In particular, the control unit 120 may control the display unit 110 to display the UI element when a predetermined event occurs before the power-on command. The predetermined event may be one that receives the motion information from the remote control device 200, or one that recognizes the motion or voice of the user. In addition to the event set by the manufacturer, an event can be set to allow the user to display the UI element.

The control unit 120 controls the display unit 110 to display the image content when the power on command is input while the UI element is being displayed. That is, the UI element is provided in an intermediate state between the power-off state of the display apparatus 100 and the power-on state. The display device 100 according to an exemplary embodiment of the present invention may provide various user experiences such as real time information, welcome message, content recommendation, external source notification connected to the display device 100, Can be provided before viewing the video content.

The control unit 120 may control the display unit 110 to stop displaying the displayed UI element after a predetermined time has elapsed after displaying the UI element. The control unit 120 may cause the power state of the display device 100 to enter the SRPO state while stopping the display of the UI element. Accordingly. The display device 100 can shorten the time required for displaying the UI element thereafter.

For example, when the user generates an event for lifting the remote control device 200 in order to know real-time weather information, the UI element is displayed only for a period of time in which the user is sufficiently aware of the weather information. Continuous UI element provision is unnecessary in terms of power consumption. In addition, if the predetermined event occurs in response to the intention of the user, the display of the UI element is stopped after a predetermined time has elapsed, so that the control unit 120 can heal the error due to the malfunction.

The control unit 120 may control the display unit 110 to display various kinds of UI elements. For example, the UI element may be a graphical object corresponding to at least one of time information, date information, traffic information, and weather information. In addition, a content recommendation screen, a service connection screen, an interactive message, or a combination thereof may be provided as a UI element according to a welcome message, a user's preference or weather, or the like.

The control unit 120 can change the displayed UI element when a predetermined second event is generated to display another UI element. For example, the predetermined second event may be at least one of connection with an external server, reception of a UI element change instruction, reception of a direction switching instruction, and reception of motion information. The reception of the command and the information may be a reception of a user input directly input to the display apparatus 100 and a reception of a control command at the remote control apparatus 200 connected to the display apparatus 100. [ For example, when the user wants to know the weather information as well as the UI element showing the time information initially displayed, the user can take an action to shake the remote control device 200. The remote control device 200 senses the shaking motion, generates motion information, and transmits the motion information to the display device 100. After receiving the motion information corresponding to the second event, the display device 100 can switch the UI element to display the weather information in the time information.

The control unit 120 may control the display unit 110 such that the UI element is displayed only on a part of the screen on which the image content is displayed. By displaying the UI elements in only a part of the screen, the user can intuitively know whether the display device 100 displays the UI element or the general image content.

When the power on command is input while the UI element is being displayed, the control unit 120 stops displaying the UI element and controls the display unit 110 to display the image content. For example, the power on command may be at least one of a power state change command, a source select command, and a channel change command.

If the power state change command is input while the UI element is displayed, the controller 120 may control the display unit 110 to display the image content displayed before the power of the display apparatus 100 is turned off. In one embodiment of the present invention, the power state change command may be transmitted to the display device 100 by pressing the power button of the remote control device 200. [ In another embodiment, the power state change command may be a voice " Power on. &Quot;

For example, if the broadcast content of the channel 11 is being displayed before the power is turned off, the control unit 120 stops the display of the UI element in response to the power state change command and displays the broadcast content on the channel 11 Can be controlled.

When the source selection command or the channel change command is input while the UI element is displayed, the controller 120 controls the display unit 110 to display the image content corresponding to the input source selection command or the channel change command. For example, the display device 100 may be connected to a set-top box (STB), a DVD player, an audio device, a game machine, a smart phone, and the like. When the source selection command is input, the control unit 120 may control the display unit 110 to display the image content input from the corresponding source device. For example, when the game device is selected as a source by pressing the source selection button of the remote control device 200, the control unit 120 may control the display unit 110 to display the game screen input from the game device.

If the channel change command corresponding to the channel # 9 is received, the control unit 120 notifies the channel change command to the channel change command corresponding to the channel change command It is possible to control the display unit 110 to display the broadcast contents at a predetermined time.

The control unit 120 may control the display unit 110 to display the image content while maintaining the display of the UI element until the image content is ready to be displayed even if the power on command is input. When the display of the UI content is stopped and the image content is displayed as soon as the power on command is input, if the image content is not ready to be displayed, a black screen is displayed on the display unit 110. Therefore, by keeping the display of the UI element until the preparation for displaying the image content is completed, the display device 100 has an effect of smoothly switching the screen.

In another embodiment, if the image content is not ready to be displayed for a predetermined time or longer, the control unit 120 controls the display unit 110 to stop displaying the UI element even if a black screen is displayed. This is because if the image content is not ready to be displayed for a predetermined time or longer, the user must be able to recognize that there is no input image.

Through the display device 100 as described above, the user can obtain various user experiences before viewing the image content through the display device 100. [

FIG. 3 is a block diagram illustrating a detailed configuration of a display device 100 according to an embodiment of the present invention. 3, the display apparatus 100 includes a display unit 110, a control unit 120, an image receiving unit 130, an image processing unit 140, an audio output unit 150, a communication unit 160, a storage unit 170, a power supply unit 180, and an input unit 190.

The display unit 110 displays a UI element including a graphic object and image contents. In particular, the display unit 110 displays a UI element when a preset event occurs before a power-on command, and displays an image content when a power-on command is input while a UI element is displayed.

The image receiving unit 130 receives image content data through various sources. For example, the image receiving unit 130 can receive broadcast data from an external broadcasting station. As another example, the image receiving unit 130 may receive image data from an external device (e.g., a DVD player) or may stream image data from an external server.

The image processing unit 140 performs image processing on the image data received from the image receiving unit 130. The image processing unit 140 may perform various image processing such as decoding, scaling, noise filtering, frame rate conversion, and resolution conversion on image data.

The audio output unit 150 can output various kinds of audio data processed by the audio processing module as well as various kinds of notification sounds and voice messages.

The communication unit 160 performs communication with an external device according to various types of communication methods. The communication unit 160 can receive an IR signal transmitted from the remote control device 200. [ The communication unit 160 may include various communication chips supporting wired / wireless communication. For example, the communication unit 160 may include a chip operating on a wired LAN, a wireless LAN, a WiFi, a Bluetooth (BT), or an NFC (Near Field Communication) method. In the case of the BT connection, various connection information such as the SSID and the session key are first transmitted and received to and from the external device, and information including the control command can be transmitted and received after the connection is completed.

The storage unit 170 stores various modules for driving the display device 100. For example, the storage unit 170 may store software including a base module, a sensing module, a communication module, a presentation module, a web browser module, and a service module. The base module is a base module that processes a signal transmitted from each hardware included in the display device 100 and transmits the signal to an upper layer module. The sensing module collects information from various sensors and analyzes and manages the collected information. For example, the sensing module may include a voice recognition module, a motion recognition module, a face recognition module, and the like. The presentation module is a module for constructing a display screen, and may include a multimedia module for reproducing and outputting multimedia contents, a UI, and a UI rendering module for performing graphics processing. The communication module is a module for performing communication with the outside. A web browser module is a module that accesses a web server by performing web browsing. A service module is a module including various applications for providing various services.

In addition, the storage unit 170 may store image contents, photographs, image files, and the like stored by the user. A photograph or the like stored in the storage unit 170 can be used to construct a UI element. For example, when displaying a UI element indicating the birthday of the user family, a picture of the family matched with the birthday stored in the storage unit 170 may be used.

When the power off command is input, the storage unit 170 may store the last screen of the displayed image contents. For example, the last screen can be stored in volatile memory. When stored in the volatile memory, the display device 100 can maintain the suspended turbo state in which the volatile memory is always powered. As another example, the storage unit 170 may store the last screen in the non-volatile memory where the user's photographs and the like are stored.

In addition, the display device 100 can use a standby mode such as SPRO by storing the state of the hardware drive at the time when the power of the display device 100 is turned off in the storage unit 170. [ Accordingly, the display apparatus 100 can save the contents stored in the storage unit 170 using the self-refresh operation of the storage unit 170 in the suspended state. When receiving a power-on command or receiving a command to display a UI element before receiving a power-on command due to a preset event occurring, it can quickly return to the operating state before power-off.

The power supply unit 180 applies power to each configuration of the display device 100. The power supply unit 180 applies power to the display device 100 when a preset event occurs. When the power supply unit 180 is in the SPRO state, the display unit 110, the audio output unit 150, the system on chip (SoC), and the like of the display device 100 are powered off and self- Only the storage unit 170 and the control unit 120 related to the resume operation are powered.

The input unit 190 receives various user commands for controlling the display device 100. For example, the input unit 190 may receive a command for displaying a UI element, a power-on command, and a power-off command. The input unit 190 may be implemented as a button, a motion recognition device, a voice recognition device, or the like. The function of the input unit 190 may be replaced with the remote control device 200. [

The control unit 120 controls the overall operation of the display device 100. The operation of the control unit 120 will be described below in detail with reference to the drawings.

The control unit 120 controls the display unit 110 to display the UI element when a predetermined event occurs before the power on command. When the power on command is input while the UI element is displayed, the control unit 120 stops the display of the UI element and controls the display unit 110 to display the image content.

According to an embodiment of the present invention, the preset event may be that motion information of the remote control device 200 is received from the remote control device 200 connected to the display device 100. For example, when the user performs an operation of lifting or touching the remote control device 200, the remote control device 200 can detect movement or user input of the remote control device 200 and transmit the motion information. The remote control device 200 may transmit a control command corresponding to the motion information.

In addition, the predetermined event may be a motion of the user on the display device 100 or a voice command. For example, the display device 100 may include a camera that senses the motion of the user. When the camera senses that the user is approaching the display device 100 or if the camera detects a predetermined user motion, the controller 120 may determine that a predetermined event has occurred. When an event for recognizing the user's voice is set, the control unit 120 not only displays the UI element on the display unit 100, but also controls the display unit 100 so that the information included in the UI element changes according to the type of the predetermined voice Can be controlled. For example, when a voice of "Hello" is input, the control unit 120 can determine that a predetermined event has occurred. When a voice called "Weather" is input, the control unit 120 may control the display unit 110 to display a UI element including weather information among various UI elements. Further, when a voice called "Movie" is input, the control unit can control the display unit 110 to display the UI element including the recommended movie content.

When the power on command is input while the UI element is displayed, the control unit 120 controls the display unit 110 to display the image content. FIGS. 4A to 4F are diagrams for explaining how UI elements are displayed and converted into a state of displaying image contents. FIG. 4A shows a screen in which a predetermined event occurs and a UI element is displayed. A diamond-shaped graphic object corresponding to weather information and a UI element including time information are displayed at the center of the screen. When the power on command is input while the UI element is displayed, the controller 120 controls the display unit 110 to stop the UI display. For natural screen switching, the control unit 120 controls the display unit 110 to pass through an intermediate step as shown in the example shown in FIGS. 4B to 4E. First, the control unit 120 controls the display unit 110 to display the UI elements in a line shape as shown in FIGS. 4B and 4C. Then, the control unit 120 controls the display unit 110 to progressively display the image contents as the UI elements deformed by the lines are divided as shown in Figs. 4D and 4E. FIG. 4F is a view after the image content is displayed in the entire area of the display unit 110. FIG.

In addition, various methods of switching from the screen displaying the UI element to the screen displaying the image content can be implemented. For example, UI elements can be merged horizontally instead of vertically. Alternatively, the screen may be switched so that the UI elements are gradually displayed lightly and the image contents are superimposed on the back surface. If the display unit 110 has an edge shape, the UI element displayed at the center of the display unit 110 may be moved to the edge portion and displayed. In this case, the display of the UI element is not interrupted, but may be displayed simultaneously with the image content. This is because, even if the UI elements are displayed together in the edge-type display device, viewing of the image contents is not hindered.

The control unit 120 controls the display unit 110 to stop the displayed UI element after a predetermined time elapses after displaying the UI element. For example, if the power-on command is not input for 15 seconds after the UI element is displayed, the control unit 120 may control the display unit 110 to stop displaying the UI element. If the power-on command does not exist until the predetermined time elapses, it may be the case that the user generates a preset event for the purpose of checking only the information displayed on the UI element. Therefore, It is appropriate from the viewpoint of power.

If an additional preset event occurs again while the UI element is displayed, the control unit 120 may reset the time count for stopping the display of the UI element. For example, if the UI element is displayed by performing the operation of lifting the remote control device 100, if the user is performing the operation of continuously shaking the remote control device 100, And controls the display unit 110 to maintain the display.

The control unit 120 may control the display unit 110 to change the displayed UI element when a predetermined second event is generated to display the UI element. For example, when a UI element providing weather information is initially displayed, there is a need to change a UI element that provides traffic information to be displayed when a user wants to know traffic information. The predetermined second event may be at least one of connection with an external server, reception of a UI element change command, reception of a direction switching command, and reception of motion information. For example, when an operation of pointing the remote controller 200 to the right is input, the controller 120 may determine that a predetermined second event has occurred. Accordingly, the control unit 120 can control the display unit 110 to display other types of UI elements.

The control unit 120 may control the display unit 110 to prevent the UI element from being displayed even if a predetermined event occurs after the power on command is input and the video content is displayed. Even if there is an operation of moving the remote controller 200 during the viewing of the image contents, the display unit 110 is prevented from displaying the UI elements that may interfere with the viewing. For example, the control unit 120 can ignore the control command received from the remote control device 200. [ The control unit 120 can prevent the UI element from being displayed during the video content viewing by not reading the signal indicating that the predetermined event has occurred in the remote control apparatus 200 or the motion recognition apparatus. As another example, the remote control apparatus 200 may not transmit a signal. This will be described in detail in the description of the remote control device 200.

However, there may be a case where the user intends to receive the UI element while viewing the image contents. In such a case, it may be appropriate to set an event that clearly identifies the user's intention, such as pressing a specific button rather than a simple action.

Figures 5A-5K illustrate various types of UI elements.

5A and 5B are diagrams showing UI elements represented by graphic objects corresponding to weather information. The controller 120 may provide real-time weather information at the time when the predetermined event occurs and the UI element is displayed. As shown in FIG. 5A, in the case of rainy weather, the UI element may be a graphical object showing a window that rains. In addition, the control unit 120 can provide a sound accompanied by rain. The user can understand the weather information more intuitively than when the weather information is provided as text. Obviously, there are embodiments in which weather information is provided as text. FIG. 5B is a diagram showing a UI element represented by a graphic object intuitively recognizing that the weather is clear. Graphics objects can be videos as well as photos. For example, the UI element in FIG. 5B may be a UI element that provides a video with a walk in sunny weather and a bright atmosphere together.

Figures 5C and 5D are diagrams illustrating UI elements that together include weather information, time information, and a message. Referring to FIG. 5C, the video, the time information, and the message "Do not forget your umbrella" are displayed together.

In addition, the control unit 120 may set individual anniversaries (ex. Birthday, anniversary) for each user in advance. The control unit 120 may use a picture stored in advance in the storage unit 170 as a graphic object by the user.

5H is a diagram showing a UI element capable of giving a user experience that seems to interact with the display device 100. [ When a preset event occurs, the control unit 120 may control the display unit 110 to display a text to be inquired to the user. Using the motion information of the remote control apparatus 200, the motion information of the user, or the voice information of the user, the control unit 120 can determine the response of the user. The control unit 120 may control the display unit 110 to display a new text corresponding to the determined user response. These interactive UI elements may simply provide an interesting user experience and may also provide a user experience to set up certain functions of the display device 100 through a conversation.

If the display device 100 can not receive real-time information or does not have graphic objects to express various UI elements, the product logo previously stored in the storage unit 170 may be displayed as a UI element. Since preferred UI elements may be different for each user, it is possible to set the product logo to be displayed as a UI element at the time of product sale. Thereafter, the control unit 120 can set a desired type of UI element to be displayed according to the setting of the user. For example, in Figure 5i, the logo of the Samsung UHD TV is displayed as a UI element. If the power-on command is received while the UI element is being displayed, the controller 120 may control the display unit 110 to display the image content together with the visual effect of separating the 'S' portion.

5J is a diagram showing a UI element for providing recommended image contents. The control unit 120 may generate the recommended video content list by analyzing the user's preference information, the latest movie information received from the external server, the recommended movie information according to the weather, and the like. 5K is a diagram illustrating a UI element including a connectable service shortcut icon. For example, when the Internet connection is established, the control unit 120 may control the display unit 110 to display an icon connected to the SNS service such as Twitter or Facebook as a UI element. In addition, the UI element may be a graphic object corresponding to various information such as traffic information.

The display device 100 according to an exemplary embodiment of the present invention may display a UI element that provides various information before viewing the image content so that the user can easily obtain desired information. The display device 100 can provide various user experiences other than viewing image contents while providing a user experience for providing image contents as in the conventional art. For example, when the user desires to know the weather and the traffic situation of the present day before the user goes to work, the user can receive desired information from the display device 100 by simply carrying the remote control device 200 with a simple operation.

FIG. 6 is a diagram for explaining a feature in which UI elements are varied according to a connection state with an external server. In FIG. 6, only the case where the video content is a broadcast signal will be described as an example. When a predetermined event occurs in a state where the power of the display apparatus 100 is turned off, the controller 120 may control the display unit 110 to display a UI element displaying a greeting message. At this time, the display device 100 may be in the SRPO state, not in the completely turned off state. The UI element can be displayed more quickly when the UI element is displayed in the SRPO state.

When the Internet connection is not established, the display device 100 can not obtain real-time information such as weather information and traffic information. Therefore, the broadcast signal can be tuned in the background while continuously displaying only the UI element displaying the greeting message. If the power on command is received while the UI element is displayed, the controller 120 controls the display unit 110 to display the broadcast content.

When the Internet connection is established, the control unit 120 controls the display unit 110 to display a UI element displaying a greeting message while receiving real-time information required to generate the UI element. When the UI element providing the date / time / weather information is prepared, the control unit 120 converts the UI element into a graphic object corresponding to the real-time information in the greeting message. At this time, the controller 120 can also tune the broadcast signal in the background. If the power on command is received while the UI element is displayed, the controller 120 controls the display unit 110 to display the broadcast content. The reason for tuning the broadcast signal in the background is that when the display device 100 enters the SRPO state due to the power-off state, the power source such as the tuning unit (not shown) is completely turned off, .

The control unit 120 controls the display unit 110 to display the image content after the display of the UI element is maintained until the image content is ready to be displayed even if the power on command is input. For example, even if the power-on command is input in FIG. 6, when the tuning of the broadcast signal is not completed, the controller 120 controls the screen so that the screen is not switched. The control unit 120 switches the screen from the UI element to the image content at the time when the tuning of the broadcast signal is completed and the broadcast contents can be displayed immediately. The same is true in the case of a source such as HDMI as well as in the case of a broadcast signal.

The control unit 120 may control the display unit 110 such that the UI element is displayed only on a part of the screen on which the image content is displayed. This is to enable the user to intuitively distinguish the case where the image content is displayed and the case where the UI element is displayed. 7A to 7D are views illustrating an example in which a UI element is displayed in a partial area of a screen displaying image contents according to various embodiments of the present invention. In FIG. 7A, the control unit 120 controls the display unit 110 to display a UI element at the center of the screen. Text corresponding to time information, weather information, and date information and a moving graphical object corresponding to weather information are displayed in the center area of the screen. In FIG. 7B, the control unit 120 displays a UI element at one corner of the screen. In this case, a user-like experience is provided. FIG. 7C is a diagram showing a case where a UI element is displayed in a small central area, and FIG. 7D is a diagram showing a case where a UI element indicating a greeting is displayed at a position corresponding to a location indicated by the remote control device 200.

As another example, in the case of the display device 100 having the display portion 110 in the form of an edge, the control portion 120 can control the display portion 110 such that the UI element is displayed in the edge region of the display portion 110 have. When the UI element is displayed in the edge area, the display of the UI element may not be stopped even when the power on command is received and the image content is displayed.

In one embodiment of the present invention, the power on command may be at least one of a power state change command, a source select command, and a channel change command. For example, if the power state change command is input while the UI element is displayed, the controller 120 may cause the display unit 110 to display the image content displayed before the power of the display apparatus 100 is turned off. The power state change command is generated when the power button of the remote control apparatus 200 is pressed, when the power button of the display apparatus 100 is pressed, when the display apparatus 100 recognizes a predetermined user's motion or voice . When the power button of the remote controller 200 is pressed while the UI element is being displayed, for example, when the video content displayed before power off is VOD (Video On Demand) video content, the controller 120 controls the VOD So that the display unit 110 can be controlled.

In another embodiment, when the source selection command is input while the UI element is displayed, the control unit 120 may control the display unit 110 to display the image content corresponding to the input source selection command. The source selection command can be generated when an external input button of the remote control device 200 is pressed. In another example, if the source selection command is input while the UI element is being displayed, the control unit 120 may control the display unit 110 to display a source selection screen as shown in Figs. 8A to 8C. 8A is a diagram corresponding to an initial screen passed to the source selection screen. In a situation where the last used source before the power-off of the display device 100 is the PlayStation 4 corresponding to the source 1, the control unit 120 controls the display 120 to provide some tilted visual effects (110). 8B is a diagram showing a case where the source is changed to a PC. As shown in FIG. 8C, when an instruction to confirm the source selection is received, the control unit 120 controls the display unit 110 to display the image contents input from the selected source together with the visual effect to be spread to the left and right.

In another embodiment, when the channel change command is input while the UI element is displayed, the controller 120 controls the display unit 110 to display the image content corresponding to the input channel change command. For example, when a channel selection command is input by pressing a number button instead of the power button of the remote controller 200, the controller 120 controls the display unit 110 to display the broadcast content of the channel.

The display device 100 according to an embodiment of the present invention may function in connection with an external device. FIGS. 9A to 9C illustrate a case of connecting to an audio device, and FIGS. 10A to 10D show a case of connecting to a smartphone.

Thereafter, if the connection state continues for a predetermined time, the equalizer and additional information of the audio device are displayed as UI elements, as shown in FIG. 9B. When the power-on command is received while the audio device is connected, the controller 120 determines that the audio device is selected as a source, and controls the display unit 110 to display a screen as shown in FIG. 9C.

As shown in FIG. 10A, when the smartphone is detected and connected to the display device 100 via the BT before receiving the power-on command, the controller 120 determines that a predetermined event has occurred, And controls the display unit 110 to display the UI element indicating the UI element. After a predetermined time has elapsed, the control unit 120 may control the display unit 110 to stop displaying the UI element.

10B to 10D, when a telephone call, a text message, or a mail is received on the connected smartphone, the controller 120 determines that a predetermined event has occurred, and displays a UI element for providing related notification information (110).

In the above description, the UI element is displayed before the power-on command to provide the user experience before viewing the image content. In the opposite case, after the power off command is issued, the UI element may be displayed or a specific function may be provided to provide a user experience after viewing the image content.

11A to 11C are diagrams for explaining a feature of extracting a dominant color after a power off command and providing a message having a background color. When the power off command is received, the control unit 120 extracts the background color from the screen at the time when the power off command is received. Then, the control unit 120 controls the display unit 110 to display a message having the extracted background color. For example, the screen shown in FIG. 11A is a screen displayed at the time when the power off command is received. The background color of the entire screen shown in Fig. 11A is orange. Upon receiving the power off command, the control unit 120 may control the display unit 110 to gradually disappear the image content screen as shown in FIG. 11B. As shown in FIG. 11C, the control unit 120 may control the display unit 110 to provide a message "Good night"

12A and 12B are diagrams for explaining a function of providing illumination in a partial area of the display unit 110 for a predetermined period of time after reception of the power off command. 12A, when the power off command is received while the image content is being displayed, the controller 120 turns off the power from the top to the bottom of the display unit 110 in order to provide a visual effect that the screen is closed as if the eyes are closed do. 12B, the control unit 120 controls the display unit 110 to display a bright screen that can be used as an illumination in a predetermined area of the display unit 110. In addition, The function of providing illumination in this way is a particularly useful function in the case of turning off the display device 100 while viewing the image contents while the external illumination is turned off at night. Since the display device 100 provides illumination for a certain period of time, it is possible for the user to move without hitting the object without turning on the external illumination.

Through various embodiments of the display device 100 as described above, it is possible to receive UI elements that provide various information before the power-on command is input.

FIG. 13 is a block diagram for explaining a configuration of a remote control device 200 according to an embodiment of the present invention. Referring to FIG. 13, the remote control device 200 includes a sensor unit 210, a communication unit 220, and a control unit 230. The remote control device 200 may be implemented by a smart remote controller. The remote control device 200 may be implemented by various devices such as a pointing device, a touch pointer, a motion recognition device, a voice recognition device, and a mouse. For convenience of explanation, the following description will be made by taking the case where the remote control device 200 is a remote control as an example.

The sensor unit 210 senses the movement of the remote control device 200. The sensor unit 210 may include an acceleration sensor, an angular velocity sensor, and a geomagnetic sensor. The acceleration sensor senses the variation of the speed with respect to the unit time. The acceleration sensor can be implemented in three axes. When implemented as a three-axis acceleration sensor, the acceleration sensors are provided with X, Y, and Z-axis acceleration sensors arranged in different directions and orthogonal to each other. The angular velocity sensor senses the angular velocity by sensing the amount of change in the predetermined direction of the remote controller 200 for a unit time. The geomagnetic sensor is a sensor that can detect the azimuth angle by detecting the magnetic field flow. The geomagnetic sensor detects the azimuth coordinates of the remote control device 200 and can detect the direction in which the remote control device 200 is laid based on the azimuth coordinates. Using the geomagnetism sensor, the sensor unit 210 may correct the motion information obtained through the acceleration sensor or the angular velocity sensor.

The communication unit 220 includes a wireless communication module and performs a wireless communication function with an external device. The communication unit 220 can transmit the motion information and the like of the remote control device 200 to the display device 100. [ The communication unit 220 includes a first communication unit 221 that performs unidirectional communication and a second communication unit 223 that performs bidirectional communication. The wireless communication method used by the first communication unit 221 is IR (InfraRed) communication, and the wireless communication method used by the second communication unit 223 may be any one of BT (Bluetooth) communication, Wifi communication, and ZigBee communication.

The control unit 230 controls the overall configuration of the remote control device 200. When the sensor unit 210 senses the movement of the remote control device 200, the control unit 230 displays the UI element previously registered in the display device 100 before displaying the power-on command to the display device 100 And controls the communication unit 220 to transmit the control command to the display device 100.

The control unit 230 first transmits the control command through the first communication unit. Since the first communication unit takes an IR communication system, it has unidirectional communication and directionality. For example, when the user touches the remote control device 200 to display the UI element, there is a possibility that the direction of the remote control device 200 is not directed to the display device 100. [ In such a case, there may arise a problem that the control command is not transmitted to the display device 100 due to the characteristics of the IR communication. Accordingly, the control unit 230 transmits the control command again through the second communication unit in the BT communication method after BT connection with the display device 100. [ In the case of BT communication, the accuracy of the transmission of the control command is guaranteed, but since it takes time to connect, it may be difficult to obtain a response to display the UI element immediately. Accordingly, the control unit 230 first transmits the control command through the IR communication, and controls the communication unit 220 to transmit the control command again through the BT communication in order to prevent the error.

The control unit 230 controls the communication unit 220 to transmit the control command every predetermined period. In particular, after the BT connection is established, the control unit 230 controls the communication unit 220 to transmit the BT signal every predetermined period.

The control unit 230 may control the communication unit 220 to stop transmitting the control command when the communication unit 220 receives information that the display device 100 displays the image content. In order to prevent unnecessary power consumption of the remote control device 200, when it is unnecessary to transmit the control command for displaying the UI element, In addition, the control unit 230 may control the communication unit 220 to resume the transmission of the control command upon receiving the information that the power of the display device 100 is turned off.

The user can be provided with a user experience through which various information is provided prior to viewing the video content by a simple operation of operating the remote control device 200 through the remote control device 200 as described above.

14 is a flowchart for explaining a control method of the display apparatus 100 according to an embodiment of the present invention. First, the display apparatus 100 determines whether a preset event has occurred before the power-on command (S1410). If the predetermined event has not occurred (S1410-N), the display device 100 waits in the suspended state. Conversely, if a predetermined event occurs before the power-on command (S1410-Y), the display device 100 displays the UI element (S1420). For example, the preset event may be to receive motion information of the remote control device 200 from the remote control device 200 connected to the display device 100. The UI element may be a graphical object corresponding to at least one of time information, date information, traffic information, and weather information. If the power-on command is input while the UI element is being displayed (S1430-Y), the display device 100 displays the image content (S1440). Various other embodiments of the control method of the display device 100 are omitted because they overlap with those of the display device 100 of the embodiment.

The remote control device 200 can detect movement using various kinds of sensors. Also, the remote control device 200 may detect whether there is an operation of touching the remote control device 200 using not only the motion but also the touch sensor. If motion is detected (S1510-Y), the remote control device 200 transmits a control command in IR mode (S1520). For example, the control command may be a control command that causes the UI element previously registered in the display device 100 to be displayed before transmitting a power-on command to the display device 100 connected to the remote control device 200. [ Then, the remote control device 200 determines whether BT connection is established with the display device 100 (S1530). If the BT connection is completed (S1530-Y), the remote control device 200 transmits the control command again to the connected display device 100 in the BT mode (S1540). It is also possible to use other methods capable of bi-directional communication instead of BT connection. Various other embodiments of the control method of the remote control device 200 will be omitted because they are duplicated in the description of the embodiment of the remote control device 200. [

According to another embodiment of the present invention, when a user command that combines specific keys of the remote control device 200 or manipulates a specific key in a specific manner is received, the display device 100 displays a message before the power on state or after the power off state So that the welcome mode can be activated. In FIGS. 27A and 28B, long pressing of the 'Power' key is shown as an example of a trigger operation capable of activating the welcome mode.

27A illustrates a general case in which the user presses the 'Power' button of the remote control device 200 to turn on the display device 100. FIG. 27A, when the display device 100 is switched to the power-on state, the control unit 120 may control the display unit 110 to display an animation effect extending from the center of the screen to the outside .

27B, when the user presses the 'Power' button of the remote controller 200 for a long press, the controller 120 controls the display device 100 to switch the welcome mode, which is not the power on state, Can be controlled.

In the above description, mainly the embodiments in which the welcome mode is provided before the power-on command is received are exemplified, but the welcome mode may be provided after the power-off command is received.

28A shows a general case in which the user presses the 'Power' button of the remote control device 200 to turn off the display device 100. The control unit 120 can control the display unit 110 so that the animation effect disappearing from the outside of the screen to the center can be displayed even when the display apparatus 100 is switched to the power off state.

28B, when the user presses the 'Power' button of the remote control device 200 for a long time, the controller 120 controls the display device 100 to switch the welcome mode, which is not the power- Can be controlled.
