DETAILED DESCRIPTION OF THE INVENTION

[59] Reference will now be made to exemplary embodiments of the invention, examples of which are illustrated in the accompanying drawings, with like reference numerals everywhere referring to like elements. Exemplary embodiments are described below with reference to the drawings.

[60] FIG. 1 is a diagram of a display system in accordance with an exemplary embodiment.

[61] The display system of FIG. 1 includes a display device 100, a glasses device 200, and a remote control device 300.

[62] The display device 100 receives and alternately displays a plurality of contents through a plurality of representations of content. The display device 100 generates synchronization signals corresponding to respective representations of the content, and sends one of the generated synchronization signals to each of the device 200 points.

[63] The device 200 points receives the synchronization signal from the display device 100 and opens the gates of the glasses in accordance with the received synchronization signal. Thus, the viewer who wears the device 200 points, can watch a specific content from a variety of contents displayed in the content representation synchronized (displayed) with the device 200 points.

[64] The remote control device 300 receives and sends a user command to the display device 100 to control the display device 100. The remote control device 300 detects the closest of the glasses devices 200-1 and 200-2 and sends a control command to control the presentation of content synchronized with the corresponding glasses device 200-1 or 200-2.

[65] Here, when frames of images of contents are alternately distributed and displayed, a presentation of content refers to a set of frames of images of the same content that are visible to a user wearing a device 200 points. However, the presentation of the content is different from the content itself. For example, when a user who wears a device 200 points in sync with a particular presentation of content switches the TV channel while watching content A, or starts watching content C by playing another DVD content, the content changes from A to C, but the presentation of the content does not change. That is, the presentation of content is a concept beyond the organization of content and is similar to a channel for presenting content.

[66] As shown in FIG. 1, the display device 100 alternately displays the first content and the second content through a plurality of representations of the content. The first device 200-1 points receives a synchronization signal corresponding to the first presentation of the content, and opens the shutter points when the first content is displayed, and the viewer who wears the first device 200-1 points can watch the first content. The second device 200-2 points receives a synchronization signal corresponding to the second presentation of the content, and opens the shutter points when the second content is displayed, and the viewer who is wearing the second device 200-2 points can watch the second content.

[67] Although the display device 100 according to FIG. 1, displays two contents and is connected to two points devices 200-1 and 200-2 corresponding to two representations of the content, it is understood that one or more other exemplary embodiments is not limited to this. For example, in accordance with one or more exemplary embodiments, the display device 100 may display three or more contents through three or more presentations of content and may be connected to three or more glasses devices.

[68] The display device 100 may communicate with the device 200 points and the device 300 remote control through various wireless technologies, such as Wi-Fi, Bluetooth, the standard Association for the transmission of infrared data (IRDA), radio frequency (RF), IEEE 802.11, WLAN, HR WPAN, UWB. LR WPAN and IEEE 1394.

[69] FIG. 2 is a block diagram of a display device 100 in accordance with an exemplary embodiment.

[70] As shown in FIG. 2, the display device 100 includes at least one receiver (e.g., a plurality of receivers 110-1-110-n), a plurality of signal processors 120-1-120-n, a display unit 130 (e.g., a display), and a controller 140. The display device 100 may be implemented using various devices, including a display unit, such as a TV, mobile phone, PDA, laptop, monitor, tablet, e-book, digital frame, kiosk, smart device, etc.

[71] At least one receiver (eg, multiple receivers 110-1-110-n) receives many different contents.

For example, each of the plurality of receivers 110-1-110-n receives broadcast program content from a broadcast station using a broadcast network or receives a content file from a web server using the Internet. Receivers 110-1-110-n may receive content from various players with a recording medium integrated in or connected to the playback device 100. A player with a recording medium refers to a device that reproduces content stored on various recording media such as CD, DVD, hard disk, Blu-ray disc, memory card, USB memory, etc.

[72] When content is received from the broadcast station, receivers 110-1-110-n may include a tuner, a demodulator, and an equalizer. Conversely, when content is received from a source such as a web server, receivers 110-1-110-n can be implemented as a network interface card. When content is received from various players with a recording medium, the receivers 110-1-110-n can be implemented as an interface unit connected to the player with a recording medium. As such, receivers 110-1-110-n can be implemented in a variety of ways.

[73] Furthermore, it is understood that receivers 110-1-110-n do not necessarily receive content from sources of the same type, they can receive content from sources of various types. For example, the first receiver 110-1 may include a tuner, a demodulator, and an equalizer, and the second receiver 110-2 may include a network interface card.

[74] Meanwhile, in FIG. 2, the display device 100 includes a plurality of receivers 110-1-110-n, but a plurality of receivers can be implemented as a single receiver depending on exemplary embodiments. That is, a single receiver can receive multiple contents.

[75] Signal processors 120-1-120-n may generate image frames by processing content received by receivers 110-1-110-n. The signal processor 120 is explained in more detail with reference to FIG. 3.

[76] FIG. 3 is a block diagram of a signal processor 120 in accordance with an exemplary embodiment.

[77] As shown in FIG. 3, the first signal processor 120-1 includes a first video processor 121-1 and a frame rate converter 122-1. Although only the first signal processor 120-1 is shown in FIG. 3, the same or similar structure to FIG. 3 can be applied to other signal processors 120-1-120-n.

[78] The first video processor 121-1 processes the video data in the content received from the first receiver 110-1. More specifically, the first video processor 121-1 may include a decoder for decoding video data and a scaler for zooming in or out on the video data in accordance with the screen sizes of the display unit 130.

[79] Furthermore, the first video processor 121-1 may convert the video data into format data corresponding to the first frame rate converter 122-1. For example, when the input video data is in the top-down format, and the first frame frequency converter 122-1 processes the frame in the side-by-side format, the first frame frequency converter 122-1 can convert the frames of the content images to the side-by-side format by arranging image frames side by side in the horizontal direction.

[80] The first frame rate converter 122-1 converts the frame rate of the content output from the first video processor 121-1 to the output frequency of the display device 100. For example, when the display device 100 operates at 60 Hz in a single presentation mode, the first frame rate converter 122-1 may convert the frame rate of each content to 60 Hz, as in the frame rate of a single presentation mode. As for the nth (for example, second, when n = 2) content in a multi-presentation mode, the display device 100 may operate at an output frequency of n * 60 Hz.

[81] Although FIG. 2, the display device 100 includes a plurality of signal processors 120-1-120-n, a plurality of signal processors may be implemented as a single signal processor depending on exemplary embodiments. That is, a single signal processor can process multiple contents.

[82] The display unit 130 alternately positions and displays frames of content images generated by signal processors 120-1-120-n. More specifically, the display unit 130 performs multiplexing to alternately arrange and display the frames of the content images output from the signal processors 120-1-120-n at least one after the other. In some cases, the display unit 130 may enlarge or reduce the frame of the content image in accordance with the screen size.

[83] For example, in a display device such as shutter glasses, the display unit 130 alternately positions and displays an image frame of the first content, an image frame of the second content, ... and an image frame of the nth content at least one after another. The user can watch the content intended for him / her by putting on the device 200 points, which works in concert on the timing of the display of content with the block 130 display. More specifically, the device 200 points includes a shutter glasses left eye and shutter glasses right eye. The shutter of the left eye glasses and the shutter of the right eye glasses alternately open and close when viewing 3D content. In contrast, when at least one image frame is positioned and displayed alternately, the shutter of the left eye glasses and the shutter of the right eye glasses open and close together, in accordance with the timing of the output of the content synchronized with the device 200 points. Therefore, the user can watch the content separately from other users.

[84] Essentially, a mode for sequentially positioning and outputting frames of content images may be referred to as a multi-view mode (or a dual-view mode). In the normal mode (or single-view mode) for displaying both two-dimensional (2D) content and 3D content, the display device 100 can process the contents by activating only one of the receivers 110-1-110-n.

When the user selects a multi-view mode in the normal mode, the display device 100 can process the data by activating one or more receivers 110-1-110-n.

[85] Meanwhile, the content may be 20 content or 3D content. 3D content gives the user the opportunity to feel the depth using multiple images representing the same object from different angles.

[86] When multiple 3D contents are used, the display unit 130 may multiplex images for the left eye of the 3D contents provided by the plurality of frame frequency converters 122-1-122-n based on a predetermined location, and arrange them in turn with image frames of other content .

[87] Therefore, the image for the left eye and the image for the right eye of the first content, the image for the left eye and the image for the right eye of the second content, ... and the image for the left eye and the image for the right eye of the nth content are arranged and displayed one after another friend. The user perceives the image for the left eye and the image for the right eye of one content through the device 200 points.

[88] The controller 140 controls the operations of the display device 100. More specifically, the controller 140 controls the receivers 110-1-110-n, the signal processors 120-1-120-n, and the display unit 130 to perform the corresponding operations.

[89] When a predetermined event occurs, the controller 140 may control the signal processors 120-1-120-n and the display unit 130 in accordance with this event.

[90] Here, a predetermined event may include an event of receiving a control command to control one of the content representations from the remote control device 300, an event of at least one of the contents not being synchronized with the device 200 points, input events of a multi-view mode launch command , an event of inputting a command request a control right from a remote control device 300, an event of inputting a command to terminate a mode with many representations, etc.

[91] The operations of the controller 140 in accordance with a predetermined event will be explained in detail below.

[92] FIG. 4 is a block diagram of a display device 100 in accordance with another exemplary embodiment.

[93] As shown in FIG. 4, the display device 100 includes a plurality of receivers 110-1-110-n, a plurality of signal processors 120-1-120-n, a display unit 130 (e.g., a display) and a controller 140, as well as a clock signal generator 150 and a block 160 interface (e.g. interface). Here, the controller 140 may control the clock generator 150 and the interface unit 160 to perform their respective functions.

[94] The synchronization signal generator 150 generates a synchronization signal to synchronize the device 200 points corresponding to the content, in accordance with the timing of the content. That is, the synchronization signal generator 150 generates a synchronization signal for opening the shutter points of the device 200 points with timing display for the image frame content in a mode with multiple representations.

[95] The interface unit 160 is connected to and communicates with at least one eyeglass device. Thus, the interface unit 160 can send a synchronization signal to the device 200 points and receive a selection command from the device 200 points, by communicating with the device 200 points in accordance with any of various wireless circuits.

[96] For example, the interface unit 160 may include a Bluetooth communication module for communicating with the device 200 points, generate a synchronization signal as a transport stream in accordance with the Bluetooth communication standard and send the transport stream to the device 200 points.

[97] The transport stream includes time information for opening or closing the shutter of the glasses of the device 200 points in synchronization with the timing of the display of content. More specifically, the time information may include information about at least one of a left shutter opening bias, a left shutter closing bias, a right shutter opening bias, and a right shutter closing bias of the device 200 points.

[98] Offset is the delay information from the reference point in time specified for each content to the time the shutter opens or closes the glasses. That is, when the offset time period elapses from the reference time, the device 200 points opens or closes the left shutter of the glasses and the right shutter of the glasses.

[99] For example, the reference point in time may be a point in time when a vertical synchronization signal (ie, frame synchronization) is generated in the image frame. The transport stream may include information about the reference point in time, and also include information about the clock signal used in the display device 100. Thus, the device 200 points, when receiving a transport stream, can synchronize its clock signal with the clock signal of the display device 100 and open or close the gates of the glasses by determining, using the clock signal, when the offset has passed since the vertical synchronization signal.

[100] In addition, the transport stream may further include information on the frame synchronization cycle and decimal point information if the frame synchronization cycle has a decimal point.

[101] Meanwhile, the interface unit 160 may perform pairing based on the Bluetooth communication scheme by transmitting the Bluetooth address and PIN code to and from the device 200 points.

[102] In an exemplary embodiment, the interface unit 160 may include multiple Bluetooth addresses, and one eyeglass device may be connected to one Bluetooth address. In this case, a Bluetooth address may be assigned to each device of the glasses in ascending or descending order, in accordance with the order in which the device 200 points is connected to the block 160 of the interface. The interface unit 160 may set an exception for the Bluetooth address used to connect to the device 200 points from the search, to prevent the connection of this Bluetooth address with another device points.

[103] When pairing is completed, information related to the device 200 points, for example, the identification information of the device points or Bluetooth address for pairing can be registered in block 160 of the interface. The interface unit 160 matches the information of the device 200 points with the transport stream corresponding to the timing of the display of content, and sends the transport stream to the device 200 points based on the information obtained by pairing.

[104] Having accepted the transport stream, the device 200 points can determine whether the transport stream matches its information device points, and open or close the glasses in accordance with the time information in the transport stream.

[105] In the present exemplary embodiment, the interface unit 160 and the glasses device 200 communicate with each other in accordance with the Bluetooth communication scheme, this is an example. However, it is understood that one or more exemplary embodiments is not limited to this. For example, in accordance with one or more other exemplary embodiments, the interface unit 160 and the eyeglass device 200 may use other communication schemes, such as infrared and Zigbee, and various wireless communication schemes for transmitting and receiving signals by constructing a short-range communication channel.

[106] In the above exemplary embodiment, the interface unit 160 is the only communication module and communicates with many device points, however, the interface unit 160 can also be implemented as many communication modules that communicate with each of the device points, depending on the example options for implementation. Alternatively, if the display device 100 supports a variety of wireless communication methods, the interface unit 160 may be configured to include a plurality of communication modules in accordance with each of the wireless communication modules. For example, the interface unit 160 may include a plurality of communication modules in accordance with various wireless communication methods, such as Bluetooth, Zigbee, Wi-Fi, etc.

[107] Although not shown in FIG. 2 - FIG. 4, the display device 100 may further include a component for providing audio data from the content for each user in a multi-presentation mode in a different way. That is, the display device 100 may further include a demultiplexer for separating the video and audio data from the content received at the receivers 110-1-110-n, an audio decoder for decoding the separated audio data, a modulator for modulating the decoded audio data into other frequency signals and an audio output unit for sending modulated audio data to the device 200 points. The output of the audio data from the audio output unit is provided to the user by the output device, such as headphones in the device 200 points.

[108] Meanwhile, in some cases, when the content includes additional information, such as an electronic program schedule (EPG) or subtitle information, a demultiplexer may further separate these additional data from the content. The display device 100 may add subtitles processed for display by an additional data processor to the corresponding image frame.

[109] FIG. 5 is a block diagram of a display device 100 in accordance with another exemplary embodiment.

[110] As shown in FIG. 5, the display device 100 includes a plurality of receivers 110-1-110-n, a plurality of signal processors 120-1-120-n, a display unit 130 (e.g., a display), a controller 140, and a remote control signal receiver 170.

[111] The remote control signal receiver 170 may receive a control command from the remote control device 300. The controller 140 may control the display device 100 in accordance with a control command received from the remote control signal receiver 170.

[112] FIG. 6 is a block diagram of a device 200 points in accordance with an exemplary embodiment.

[113] The device 200 points from FIG. 6 interacts with the display device 100 of FIG. 2, which alternately displays a plurality of content based on image frames and includes an interface unit 210 (e.g., an interface), a controller 220, a glasses shutter drive unit 230 (e.g. a glasses shutter drive), an input unit 240 (e.g. an input device), block 250 of the first shutter points (for example, the first shutter of glasses) and block 260 of the second shutter of glasses (for example, the second shutter of glasses).

[114] The interface unit 210 communicates with the display device 100. For example, the interface unit 210 may be used using a Bluetooth communication module to receive a synchronization signal and send information about the device 200 points by communicating with the device 100 display. The interface unit 210 may send a user command (or control command) inputted through the input unit 240 to the display device 100.

[115] As previously indicated, the synchronization signal may be received as a transport stream in accordance with the Bluetooth communication standard and may include information on the opening or closing times of the first block shutter unit 250 and the second block block 260 of the glasses device 200 points in synchronization with timing display content. The information included in the transport stream has been described using the example of FIG. 4 and will not be explained further.

[116] The controller 220 controls the operations of the device 200 points. In particular, the controller 220 controls the eyewear shutter drive unit 230 by sending the synchronization signal received by the interface unit 210 to the eyewear shutter drive unit 230. That is, based on the synchronization signal, the controller 220 controls the eyeglass shutter drive unit 230 to generate a trigger signal for actuating the first eyeglass shutter unit 250 and the second eyeglass shutter unit 260.

[117] The eyeglass shutter drive unit 230 generates a trigger signal based on a synchronization signal received from the controller 220. In particular, based on the sync signal, the eyeglass shutter drive unit 230 can open at least one of the first shutter unit 250 and the second shutter unit 260 points in accordance with the timing of the display of one of the contents displayed by the display device 100.

[118] The first shutter block 250 and the second shutter block 260 open or close the shutter points in accordance with the trigger signal from the block 230 drive shutter glasses. For example, block 250 of the first shutter of glasses and block 260 of the second shutter of glasses open the shutter of the glasses at the same time when one of the contents is displayed, and close the shutter lenses when the other content is displayed. Therefore, a user wearing the device 200 points can watch one content from a variety of displayed content.

[119] Meanwhile, with regard to 3D content, the first shutter block 250 and the second shutter block 260 can open and close the glasses in turn. That is, in accordance with the trigger signal, the first shutter unit 250 can open when the image for the left eye from 3D content is displayed, and the second shutter unit 260 can open when the image for the right eye from 3D content is displayed.

[120] The input unit 240 receives a user command for controlling the display device 100. In particular, the input unit 240 may receive a selection command to select one of the content representations. To accomplish this, the input unit 240 may include a button, a touch panel, or a toggle button by which the user can select a presentation of the content. If the user enters a command to select one of the plurality of content representations into the input unit 240, the interface unit 210 may transmit information related to the selected content representation to the display device 100 and receive a synchronization signal corresponding to the selected content representation from the display device 100. In addition, the input unit 240 may receive a response signal for confirming or rejecting a user command or a control command for managing content images.

[121] Hereinafter, the operations of the display device 100 in accordance with predetermined events are illustrated by examples.

Event of receiving a control command to control one of the content views

[122] FIG. 7 is a diagram illustrating the effect of a control command received from the remote control device 300 on another representation of the content.

[123] When a plurality of viewers wears devices 200-1 and 200-2 points synchronized with different representations of the content, and one user watching the content enters a user command to control his / her presentation of the content, this user command may affect the user, watching content in a different presentation of the content. Because users watch their own content, they can sometimes control the display device 100 without notifying other users. For example, when the content viewed through the device 200-1 points shows a dramatic series, and the film in the content viewed through the other device 200-2 points ends, as shown in FIG. 7, a user wearing another device 200-2 points can turn off the display device 100. In this case, the presentation of the content of the device 200-1 points is undesirable, and, accordingly, it is necessary to notify the other user of the entered control command and seek consistency in management, in accordance with the type of control command.

[124] According to an exemplary embodiment, when receiving a control command to control one of the content representations, the controller 140 may selectively display a message informing of the control command entered in the other content representation according to the type of the control command. As mentioned above, when a control command is input to the display device 100 from the glasses device 200-1 or 200-2 viewing one content view, this control command may affect another content view. However, the management team may not affect another presentation of the content, or the effect, if any, may be ignored. Therefore, when a control command is received from the remote control signal receiver 170, in accordance with the type of the control command, the controller 140 controls to provide notification of the control command entered by another presentation of the content, or performs a control operation when there is no need to provide a notification.

[125] The control team is divided into an executable operation and an operation with a restriction of execution based on the impact on another presentation of the content. When there is no impact on another presentation of the content, the control team is defined as an executable operation in any case. Conversely, when another presentation of the content is impacted, the execution may change in accordance with the consent or disagreement of another user or with other conditions. In this case, the control command is defined as an operation with execution restriction.

[126] An executable operation indicates a control command when another representation of the content is not affected, as mentioned above. A control command for the operation to be performed may include a content change command for changing the content of the content presentation, a volume control command for adjusting the volume of the audio content signal, an on-screen display menu (OSD) command for displaying the OSD menu in the content presentation, and an image quality adjusting control command for adjusting image frame quality displayed in the selected content view.

[127] For example, when a volume control signal is input from one device 200 points and the volume control of the corresponding device 200 points is performed, another presentation of the content is not affected at all. Therefore, the volume control operation is among the operations performed. However, since a control command for controlling the output volume (overall volume) of the display device 100 may affect another presentation of the content, such a control command is a run restriction command. For example, with regard to a content change operation, various contents may be viewed through a single content presentation. Therefore, changing the content of one content view does not affect other content views.

[128] An operation restricting execution denotes a control command in which another representation of the content is exposed. For example, the operation with the restriction of execution includes the operation of controlling the on-off power and the operation of controlling the output characteristic of the display device 100. That is, a user watching a single presentation of the content may turn off the display device 100. In this case, the user will no longer be able to watch another presentation of the content and, accordingly, the operation of turning the power on / off is among the operations with a limited execution. Further, the operation of controlling the output characteristic denotes a command for controlling the dependent parameters of the display device 100. For example, the brightness of the screen may be adjusted or the method of reception may change.

[129] FIG. 8 is a block diagram of a display device 100 in accordance with another exemplary embodiment.

[130] The device 100 of FIG. 8 recognizes an executable operation and an operation with a restriction of execution and may further include a memory unit 180 (for example, a storage device) for storing information about a control operation divided into an executable operation and an operation with a restriction of execution.

[131] Having received the control command from the remote control signal receiver 170, the controller 140 can determine whether the received control command is an executable operation or a restriction execution operation by comparing the received control command with information about the control operation stored in the memory unit 180.

[132] When a control command relates to an executable operation, the controller 140 performs a control operation corresponding to a control command for presenting content. That is, for a control command related to controlling the volume of the content presentation, the controller 140 sends a volume control signal without providing a notification in the other content presentation. Conversely, when the control command refers to a run-limited command, the controller 140 controls the signal processor 120 and the display unit 130 to display a message notifying the control command entered in another representation of the content. For example, the signal processor 120 converts the message related to the control command into image data and combines this image data with an image frame of another content representation. The display unit 130 outputs the combined image frame to another content representation. For example, when a shutdown control signal is inputted through one content view, the message “Channel 1 user wants to turn off the display” may be displayed in another content view.

[133] At this time, a user watching a different presentation of the content may send a response signal to the display device 100 to agree or disagree with the control command. For example, the device 200 points can receive a signal for agreement or disagreement with the control command from the user through the input unit 240 and send the signal to the display device 100 using the block 210 of the interface. The user can send the signal through the remote control device 300 or directly input the signal through an input unit (eg, an input device) of the display device 100. In the event that the signal is inputted through the input unit 240 of the device 200-1 points, and a response signal consistent with the control command is received from another device 200-2 points consistent with the other content presentation, the controller 140 performs a control operation corresponding to the control command . When a response signal is received that does not agree with the control command, the controller 140 does not perform a control operation corresponding to the control command. That is, when an input signal is received to turn off the display device 100, the controller 140 displays the message “Channel user 1 wants to turn off the display. Do you agree with this? ”In another presentation of the content. When a response signal consistent with the control command is received from the interface unit 210 of another device 200-2 points, consistent with a different presentation of content, the controller 140 turns off the display device 100.

[134] Meanwhile, if, after a predetermined period of time, the display device 100 does not receive a response signal, priority may be given to presenting the content with the entered control command, and the control operation corresponding to the control command may be performed. That is, in the absence of receiving a response signal to the control command from another device 200 points, consistent with a different presentation of the content for a predetermined period of time counted from the moment the message was displayed, the controller 140 may perform a control operation corresponding to the control command. However, priority can be given to another presentation of the content, taking into account the impact on another presentation of the content, and thus, the reception of the response signal of disagreement can be determined. When the control commands are differentiated and the response signal is not received, the control operation corresponding to the control command can be performed by determining the reception of the response signal of disagreement with a large influence on another presentation of the content and determining the reception of the signal of consent with a small influence.

[135] Accordingly, the execution of the control operation may be different depending on the influence of the control command entered in one of the content representations on the other content representation. In particular, a more stable display with multiple representations can be achieved by notifying, in a different presentation of the content, a large impact on the other presentation of the content, and obtaining consent for execution.

[136] Meanwhile, in the above exemplary embodiment, if a control command relating to an operation with a restriction of execution has been entered, another presentation of the content is notified that the control command has been entered and that agreement to execute has been obtained. However, in some cases, a control operation corresponding to a control command may be performed with respect to presenting the content for which this control command has been entered without notifying another representation of the content that the control command has been entered. For example, if the command to turn off the power of the display device is entered, only the presentation of content for which this command is entered can be completed to turn off the power of the display device, without notifying other representations of the content that the command has been entered.

An event in which at least one of the content representations is not synchronized with the device points

[137] When it is detected that the content is not connected to the device 200 points, the controller 140 controls to add and display a message object that directs the connection of the device 200 points in a content representation that is not consistent with the device 200 points, which is explained below with with reference to FIG. 9.

[138] FIG. 9 is a diagram of a message object displayed to provide guidance for connecting a device 200 points in accordance with an exemplary embodiment.

[139] The device 200-1 and 200-2 points communicate with the device 100 display, using their own identification information. When the glasses devices 200-1 and 200-2 are paired with the display device 100, the identification information of the glasses devices 200-1 and 200-2 is transmitted to the display device 100. In another exemplary embodiment, the Bluetooth address of the interface unit 160, which is used to communicate with the device 200-1 and 200-2 points, can be used as identification information. According to the identification information or the Bluetooth address received from the devices 200-1 and 200-2 of the glasses, the interface unit 160 of the display device 100 transmits any of the synchronization signals corresponding to the presentations of the content to the devices 200-1 and 200-2 of the glasses. In doing this, matching information between the content presentations and the glasses devices 200-1 and 200-2 may be generated or stored.

[140] Here, the interface unit 160 of the display device 100 may check the matching information reflecting the matching between the contents and the glasses devices 200-1 and 200-2 under the control of the controller 140, and determine whether these contents include content that is not compatible with the devices 200-1 and 200-2 points.

[141] Upon detection of content that is not synchronized with devices 200-1 and 200-2 points, the signal processor 120, from a variety of processors 120-1-120-n, can add a message object to process content not synchronized with the device 200 points which controls the connection of the device 200 points to the image frame of the corresponding content, and the display unit 130 may display the image frame of the added message object, alternately with the image frame of other content.

[142] When a new glasses device 200 is connected, the controller 140 may control to automatically synchronize the new device 200 points with the presentation of content not synchronized with the device 200-1 and 200-2 points. When the corresponding presentation of the content is consistent with at least one device 200 points, according to the message object that directs the connection of the device 200 points, the controller 140 may control to make the message object displayed in the corresponding content representation disappear.

[143] As shown in FIG. 9, the display device 100 displays the second content, and the device 200-1 and 200-2 points are synchronized with the first presentation of the content and the third presentation of the content, respectively. When the second content is displayed, all the shutter points of the device 200-1 and 200-2 points are closed. Since in this case there are no glasses synchronized with the second presentation of the content, the display device 100 can add and display a Please Connect Glasses message object, which manages the connection for the second content presentation and the device 200 points.

[144] Meanwhile, viewers who wear the device 200-1 and 200-2 points and watch the first and third content cannot see the message object displayed in the second content, while the viewer looking at the display screen without the device glasses a display screen consisting of superimposed content images, and to see a message object added to the second content and superimposed on other content images. Thus, the viewer looking at the display screen without the device 200 points, can find out that part of the current representations of the content is displayed without synchronization with the device 200-1 and 200-2 points.

[145] Here, when the point device 200 is connected to the display device 100, the new point device 200 may automatically match a second presentation of content that is not consistent with the existing point devices 200-1 and 200-2.

[146] The message object that controls the connection of the device 200 points may not only be the message object of FIG. 9, but also any other object providing a notification that there is no matching of the corresponding content with the glasses 200. For example, the message object may include a message notifying that there is no agreement, such as “Glasses are not connected”, or a message providing details regarding connecting glasses.

[147] Thus, the user can intuitively understand that the specific content is not currently connected to the device 200 points without distracting the viewer watching the content in a multi-view mode, and the content not connected to the device 200 points can be matched with the new device points more simply.

Multiple View Mode Launch Command Input Event

[148] When the predetermined event is the input event of the multi-view mode launch command, and when the multi-view mode start command is input, the controller 140 may control to display a message object asking whether to synchronize the corresponding content representation in the image frame of each content representation , and in order to consistently coordinate the content with the devices 200-1 and 200-2 points, as described below with reference to FIG. 10A and FIG. 10B.

[149] FIG. 10A and FIG. 10B depict a message object displayed to ask whether to synchronize with content in accordance with an exemplary embodiment.

[150] When a user enters a multi-view mode launch command, the display device 100 alternately displays a plurality of contents, initiating a multi-view mode. Here, the signal processors 120-1-120-n may add a message object asking whether to match the corresponding content in the image frame of each content, and the display unit 130 may alternately display the image frames of the added object.

[151] The interface unit 160 sequentially matches the presentation of content to the glasses 200-3, 200-4 and 200-5 connected to the display device 100. Here, one representation of the content is consistent with a predetermined time, and when a predetermined time passes, another representation of the content may be negotiated. This applies to a plurality of glasses devices 200-3, 200-4, and 200-5 connected to the display device 100.

[152] Meanwhile, when receiving a response to the message from at least one device 200 points, the block 160 of the interface can coordinate the presentation of the content displayed at the time of receipt of the response, with the device points, which sends a response. The response to the message means the input of the content selection command through the input unit of devices 200-3, 200-4 and 200-5 points or through a remote control device.

[153] As shown in FIG. 10A, the display device 100 alternately displays the first, second, and third contents, and currently displays a picture frame of the first presentation of the content. The message object “Please click to view this image on the screen” is added to the image frame of each content. Meanwhile, all of the devices 200-3, 200-4 and 200-5 points are consistent with the first presentation of the content. When the selection command for selecting the first content that is currently already agreed upon is inputted through the input unit 240-3 of the left score device 200-3, the left score device 200-3 sends a selection command to the display device 100. Even when the predetermined time interval ends, the communication interface unit 160 of the display device 100 can save the matching of the left device 200-3 points and the first content.

[154] In FIG. 10B, the glasses device 200 is consistent with the second presentation of the content after the predetermined time interval of FIG. 10A. However, since the left glasses device 200-3 continues to continuously coordinate with the first presentation of the content by sending a selection command to the display device 100 in FIG. 10A, a viewer who wears the left glasses device 200-3 can continue to watch the first presentation of the content. Meanwhile, the message object requesting approval is not added to the image frame of the first presentation of the content agreed upon at a predetermined time. Therefore, the viewer selecting the first content can watch the first content without interruption by the object when a predetermined time passes.

[155] When the user enters a selection command through the input unit 240-4 of the device 200-4 points, consistent with the second content in FIG. 10B, the device 200-4 points sends a selection command to the display device 100, and the communication interface unit 160 of the display device 100 stores the matching of the device 200-4 points and the second content.

[156] Accordingly, the user can intuitively distinguish between the beginning of a multi-presentation mode and entering a selection command to view specific content.

[157] The message object requesting approval from the corresponding content is not limited to the message object of FIG. 10A and FIG. 10B in one or more other exemplary embodiments. That is, in accordance with one or more exemplary embodiments, any object that leads to agreement with the corresponding content may be used. In addition, a timer showing the remaining time can be added and displayed in the image frame of the corresponding content so that the user can find out the remaining time for entering the selection command to select the content.

An event in which the remote control device enters a command request right control

[158] When the predetermined event is an input event of a command request right control from the remote control device 300 and when a command request right control is entered, the controller 140 may control to add and display an image object indicating a control right in an image frame of one of a plurality contents as described below with reference to FIG. 11A and FIG. 11B.

[159] FIG. 11A and FIG. 11B depict an image object indicating a control right in accordance with an exemplary embodiment.

[160] When a control right request command is inputted from the remote control device 300, an image processor for processing content displayed through an authorized content view from a plurality of content views in the display device 100 may add an image object indicating a control right to the image frame of the corresponding content.

[161] The controller 140 may perform a control to sequentially change content displaying an image object each time a control right request command is entered. That is, when an image object is added and displayed in the image frame of any one content, and the command request right control is again entered from the remote control device 300, the image object indicating the control right is added and displayed in the image frame of any other content. Each time a control right request command is entered, the content displaying the image object may be sequentially changed. Consequently, the viewer can intuitively and easily distinguish between the authorized presentation of the content.

[162] A control right request command denotes a user command that is entered by a user watching the content through any one of the content representations in order to control the corresponding content representation. A command request right control can be entered by pressing or touching a specific button on the remote control device 300, and a command entered to control the display device 100, for example, pressing a channel or volume control button, can be recognized as a command request right.

[163] As shown in FIG. 11A, a request for a control right is input from the user remote control device 300, and a star-shaped image object indicating the control right is added and displayed in the image frame of the second content. The viewer who wears the device 200-6 points, consistent with the second content, and watches the second content, can recognize the image object indicating the control right displayed on the display device 100 and control the second content using the remote control device 300. Here, managing the second content may correspond to controlling the volume that corresponds to the second content, setting the display environment of the second content, or viewing other content by switching to another channel if the second content is a broadcast program.

[164] Meanwhile, the viewer who wears the device 200-7 points, consistent with the third presentation of the content, can neither recognize the image object nor manage the third content.

[165] Here, when the user re-enters the control right request command, a star-shaped image object indicating the control right is added and displayed in the image frame of the third content. In FIG. 11B, the display device 100 displays third content with an added image object, and the viewer who wears the device 200-7 points can see the image object added to the third content. The viewer watching the second content can neither recognize the image object nor control the second presentation of the content.

[166] When the command to request control rights is re-entered, a star-shaped image object is added and displayed in the image frame of the first content, and it can be changed sequentially each time a command to request control rights is entered.

[167] An image object indicating a control right can be not only a star-shaped image object, but also any image that the viewer can recognize. One or more exemplary embodiments is not limited to an object of the image, but can be applied to some object of the message, such as "control", indicating the right to control. When the command request for the right to control is not re-entered within a predetermined time, the controller 140 can make the image object disappear after a predetermined time.

[168] A command to request a control right can be entered not only by the remote control device 300, but also by the input unit 240 of the device 200 points in one or more other exemplary embodiments. In this case, the image object indicating the control right can be added and displayed in the content representation corresponding to the device 200 points, where the command request control rights.

Multiple View Mode End Command Input Event

[169] When a predetermined event is an event for inputting a multi-view mode completion command and when a multi-view mode completion command is entered, the controller 140 may control to add and display a message object notifying the completion of the multi-view in all image frames contents as described below with reference to FIG. 12.

[170] FIG. 12 depicts a message object notifying completion of a plurality of representations in accordance with an exemplary embodiment.

[171] When the multi-view mode completion command is inputted by the remote control device 300, the display device 100 may add and display a message object notifying of the completion of the multi-view mode in the image frames of all displayed contents, and end the multi-view mode.

[172] As shown in FIG. 12, when the multi-view mode completion command is inputted by the remote control device 300, the display device 100 adds and displays a message object notifying of the completion of the multi-view mode, such as “Exit the multi-view mode”, in image frames all of the first , second and third displayed content. Therefore, the viewer can intuitively understand that the multi-view mode is completed.

[173] A multi-presentation mode completion command can be entered not only by the remote control device 300, but also by the input unit 240 of the glasses device 200 in one or more other exemplary embodiments.

[174] When the multi-view mode is completed, only content displayed before the multi-view mode is displayed, and other contents are no longer displayed. However, it is understood that one or more exemplary embodiments is not limited to this. For example, in accordance with one or more exemplary embodiments, only content having control right up to a multi-presentation mode may be displayed, and other contents may not be displayed.

[175] Although in the example embodiments described your implementation, the object is (but is not limited to) a message object or an image object, various objects, such as an icon, logo, text label and symbol, may be represented in accordance with a predetermined event .

[176] Adding an object to an image frame in a signal processor 120 may be performed by an image processor video processor, and a frame frequency converter may add an object to an image frame with a converted frame frequency. Also, an additional data processor for processing subtitles can add an object. That is, when the content is generated as image frames, the object can be added at any phase before the content is displayed on the display unit.

[177] Meanwhile, if the user watching the content view A enters the command to complete the multiple view with respect to the content view A while the content views A and B are displayed in the multi-view mode, the display device 100 may switch to the single-view mode. In this case, the display device 100 can continuously output the content of the presentation B of the content for which the multiple presentation completion command has not been entered in a single presentation mode. When a mode is switched to a single-view mode, it is no longer necessary for the user to wear a glasses device, and thus, the display device 100 can add and output a message object, such as “The multi-view mode has ended. You can remove the device points. " Accordingly, a user watching the content view B can find out that the multi-view mode has ended. However, if the content displayed in the content view B is 3D content, the user must continue to wear the eyeglass device to watch the 3D content. In this case, a message object can be added informing that the mode has switched to 3D mode with one view, such as “The mode with many views has ended, and the mode will be switched to 3D mode.

[178] In another embodiment, if the multi-view mode has ended, an interface may be provided for selecting a single presentation of the content from the multiple representations of the content to display it in the single-view mode.

[179] FIG. 13 is a block diagram of a remote control device 300 in accordance with an exemplary embodiment.

[180] As shown in FIG. 13, the remote control device 300 includes a detection unit 310 (e.g., a detector or sensor), an input unit 320 (e.g., an input device), a control unit 330 (e.g., a controller), and an interface unit 340 (e.g., an interface).

[181] The detection unit 310 receives signals from a plurality of points devices 200 corresponding to a plurality of presentations of content, detects a points device 200 closest to the remote control device 300, and sends the detected signal to the control unit 330 of the remote control device 300.

[182] More specifically, the detection unit 310 can determine the distances between the 200 point devices and the remote control device 300, and among the 200 point devices, detect a 200 point device closest to the remote control device 300.

[183] In this case, the detection unit 310 can detect the device 200 points using a detection method, such as radio frequency identification (RFID) or a magnetic sensor, which makes it possible to register small distances between the remote control device 300 and the device 200 points.

[184] Using the RFID as the detection method, the detecting unit 310 can compare the reception intensity of the radio frequency (RF) signals received from the device 200 points, and determine the device 200 points, which transmits an RF signal having a maximum reception intensity, as the nearest device points .

[185] The point device 200 may further include a signal output unit 270 (eg, an output device) (see FIG. 14). FIG. 14 is a block diagram of a glasses device 200 in accordance with another exemplary embodiment. The signal output unit 270 of the glasses device 200 may include an RFID tag or component corresponding to a method for determining the distance of the remote control device 300. In more detail, when the remote control device 300 registers the distance to each eyeglass device using an RFID, the signal output unit 270 may include an RFID tag.

[186] The input unit 320 of the remote control device 300 receives a user command. The input unit 320 may utilize various input interfaces, such as a keyboard, touchpad, scroll wheel, joystick, dial, etc., at least individually or in combination, to switch a channel or change the audio volume.

[187] When the user selection command is inputted using the input unit 320, the control unit 330 generates a control signal for controlling the presentation of the content corresponding to the nearest 200 points device found among the 200 points devices in accordance with the user selection command.

[188] The control signal may include at least one of the glasses device IDs, which is identification information of the nearest glasses device 200, or content presentation information corresponding to the nearest glasses device 200, and a control command for controlling the content presentation of the display device 100 .

[189] To accomplish this, the remote control device 300 may receive information regarding the presentation of content corresponding to the device of glasses from the device of glasses. According to an exemplary embodiment, each eyeglass device may include information related to the presentation of content that may be included in the signal, an output signal for recording a distance, and the control unit 330 may generate a control signal using information related to the presentation of content nearest device points. According to another exemplary embodiment, if the closest eyeglass device is determined, the control unit 330 may request and receive information regarding the presentation of content from the nearest eyeglass device. Although the glasses device 200 and the remote control device 300 can transmit / receive information regarding the presentation of content using the input unit 270 and the detection unit 310, they can also be configured to include a separate interface unit for transmitting / receiving information in regarding the presentation of content.

[190] The control command may include, for example, any one of such commands as a content change command for changing content in a content presentation corresponding to the closest device 200 to the remote control device 300, a volume control command for adjusting the volume of the content audio signal, command displaying the OSD menu to display the OSD menu in the content view and an image quality adjustment control command for adjusting the quality of the image frame displayed in the view content, etc.

[191] The interface unit 340 sends a control signal generated by the control unit 330 to a remote control signal receiver 170 of the display device 100. The communication between the interface unit 340 and the remote control signal receiver 170 may involve a communication scheme such as Bluetooth, infrared and Zigbee, and various wireless communication schemes for transmitting and receiving signals over a communication channel, for example, a short-range communication channel.

[192] In the present exemplary embodiment, the user can selectively control the content presentation corresponding to the nearest device 200 points by changing the location of the remote control device 300 without having to repeatedly enter a user command to selectively control one of the content representations. It is worth noting that the message or image object can be added and displayed in the content view, which can be controlled at the moment.

[193] FIG. 15 is a flowchart of a method for controlling a display device 100 in accordance with an exemplary embodiment. Redundant descriptions regarding the display device 100 will be omitted here.

[194] The display device 100 receives a plurality of contents (operation S1510). More precisely, the display device 100 receives many different contents. Further, the display device 100 generates image frames (operation S1520). The display device 100 may generate image frames by processing received contents. The display device 100 alternately displays image frames (operation S1530). That is, the display device 100 generates a plurality of content representations and alternately displays frames of content images corresponding to the content representations.

[195] Here, when a predetermined event occurs (operation S1540-Y), the display device 100 performs an operation corresponding to this event (operation S1550). A predetermined event may include an event of receiving a control command to control one of the content representations from the remote control device 300, an event in which at least one of the contents is not synchronized with the device 200 points, an input event of a multi-view mode launch command , an event of inputting a command request a control right from a remote control device 300, an event of inputting a command to terminate a mode with many representations, etc.

[196] The event of receiving a control command from the remote control device 300 to control one of the content representations is explained below with reference to FIG. 16 and FIG. 17.

[197] FIG. 16 is a flowchart of a method for controlling a display device 100 in accordance with another exemplary embodiment, and FIG. 17 is a flowchart of a method for controlling a display device in accordance with another exemplary embodiment.

[198] The receivers 110 of the display device 100 receive a plurality of contents (operations S1610 and S1705), and the signal processors 120 generate image frames by processing the contents (operations S1620 and S1710). The display unit 130 outputs a plurality of content representations by combining frames of the content images (operations S1630 and S1715), and the synchronization signal generator 150 generates synchronization signals to synchronize the content presentations and the device 200 points (operations S1640 and S1720). The interface unit 160 transmits synchronization signals to the device 200 points (operations S1650 and S1725). When a control command is entered for any one presentation of content (operations S1660-Y and S1730-Y), while a plurality of representations of content is output, the display device 100 determines whether the control command is an executable operation. Having determined the executable operation (operation S1735-Y), the display device 100 performs the operation corresponding to the control command (operation S1737). Having determined the operation with a restriction of execution (operation S1735-Y), the display device 100 displays a message notifying of the input of a control command in another representation of the content (operation S1740). When the consent signal to the operation with a restriction of execution is received from the device 200 points, consistent with the other content presentation (operation S1745-Y), or when the consent signal is not received and when no signals are received for a predetermined period of time (operation S1755-Y ), the display device 100 performs an operation corresponding to a control command, similar to the case of an executable operation (operation S1737). Conversely, having received the signal of disagreement (operation S1750-Y), the display device 100 does not perform the operation corresponding to the control command.

[199] Meanwhile, when the predetermined event is an event in which at least one of the presentations of the content is not consistent with the device 200 points in FIG. 15 and content representations include a content representation not consistent with the device 200 points, the method adds and displays a message object that controls the connection of the device 200 points in the image frame of at least one presentation of content that is not consistent with the device 200 points.

[200] When the predetermined event is the input event of the multi-view mode launch command and the multi-view mode start command is input, the display device 100 adds and displays a message object asking whether to synchronize the corresponding content representation in the image frame of each content representation, and consistent content with devices 200 points. Upon receiving a response to the message from at least one device 200 points or from the device 300 remote control, the display device 100 can coordinate the content displayed when the response is received, and the device 200 points that sent the response.

[201] When the predetermined event is an input event of a command request right control from the remote control device 300 and a command request right control is entered, the display device 100 adds and displays an image object indicating a control right in the image frame of one of the contents. The content displaying the image object may be sequentially changed each time a command for requesting control rights is entered.

[202] When the predetermined event is the input event of the multi-view mode completion command and the multi-view mode completion command is input, the display device 100 adds and displays a message object notifying the completion of the multiple views in image frames of all contents.

[203] FIG. 18 is a flowchart of a method for controlling a remote control device 300 in accordance with an exemplary embodiment.

[204] As shown in FIG. 18, the remote control device 300 receives signals continuously generated by the device 200 points through the detection unit 310 (operation S1810), and calculates the distances between the remote control device 300 and the device 200 points by analyzing these signals (operation S1820).

[205] The control unit 330 receives the calculated values from the detection unit 310 and selects a point device 200 closest to the remote control device 300 (operation S1830). When a user command is inputted by the input unit 320 (operation S1840), the control unit 330 generates and transmits a control command to the display device 100 via the interface unit 340 (operation S1850).

[206] The display device 100 receives a control command by the remote control signal receiver 170, and the controller 140 of the display device 100 controls the presentation of the content synchronized with the selected device 200 points by analyzing the received control command (step S1860).

[207] Essentially, when users who put on the glasses device 200 and simultaneously watch the selected content views through the display device 100 control their content views, each user can easily control the content and sound of his / her content presentation by simply presenting the remote control device 300 control closer to your device 200 points than to other devices 200 points, and entering the intended control command, without the need for preliminary implementation of separate ny manipulations with the regime.

[208] Meanwhile, a program for implementing methods in accordance with various exemplary embodiments may be stored on different recording media.

[209] In particular, the code for implementing the methods may be stored on various non-volatile storage media such as flash memory, read-only memory (ROM), erasable programmable read-only memory (EPROM), electrically erasable programmable read-only memory (EEPROM), hard drive, removable disk, memory card, USB-memory and CD-ROM.

Display device based on polarized light method and glasses device

[210] The various exemplary embodiments mentioned above may be performed by a display device based on a polarized light method and a glasses device. Below, the configuration and operation of the display device based on the polarized light method and the glasses device will be explained with reference to FIG. 19 - FIG. 23.

[211] The configuration and operation of the display device based on the polarization method will be explained below.

[212] FIG. 19 is an image of an example embodiment of a system by which a polarized image can be viewed.

[213] As illustrated in FIG. 19, a system by which a polarized image can be viewed includes a display device 100 and a glasses device.

[214] The display device 100 is a component that outputs an image, and in particular, outputs an image that is polarized in a specific direction, such as a horizontal direction or a vertical direction. As illustrated in FIG. 19, if the display device 100 outputs an image that is polarized in the vertical direction A, the glasses device can only transmit an image that is polarized in the horizontal direction B and block an image that is polarized in the vertical direction A. In this case, the viewer who wears glasses, will not be able to view an image that is polarized in the vertical direction. As such, the display device 100 includes various polarization means or mechanisms for polarizing the output images.

[215] As an example of polarization means, the display device 100 may further include a polarization panel. A polarization panel is provided on the screen surface of the display device 100 and polarizes the image output from the display device 100 in a predetermined direction. Polarization can be performed as one of linear polarization, left circular polarization and right circular polarization.

[216] However, in order to provide multiple representations displaying multiple contents or display 3D content including an image for the left eye and an image for the right eye, in accordance with various exemplary embodiments of the invention, the display device can output a polarized image in many directions . The method can be divided into a phase plate pattern method and an active phase plate method.

[217] FIG. 20 is an image presented to explain a phase plate pattern method according to an exemplary embodiment. According to FIG. 20, by way of example, it is ensured that the polarization can be set differently by means of a polarization panel having different light axes for each portion of the displayed image. Such a method is referred to as a phase plate pattern method, and such a polarizing panel includes a phase plate pattern 132.

[218] The phase plate template 132 is attached to the display panel 131 of the display device. The phase plate pattern 132 includes first patterns that refer to odd-numbered lines in the pixel array of the display panel 131, and second patterns that refer to even-numbered rows in the pixel array of the display panel 131. As mentioned above, in this case, the light axis of the first patterns and the light axis of the second patterns are different from each other. For example, each of the first patterns and the second patterns can delay the front of the incident light at ¼ and -¼ wavelengths, respectively. In this case, linearly polarized light is converted into circularly polarized light in the other direction. That is, the first templates of the phase plate template 132 can convert the light of the image displayed in the line of the odd-numbered pixel array to the light with left circular polarization, and the second templates of the phase plate 132 template can convert the light of the image displayed in the line of the even-numbered pixel array, into the light with right circular polarization.

[219] In this case, the polarizing filter of the first glasses device may have the same polarization axis as the first phase plate pattern templates 132. In addition, the polarizing filter of the second glasses device can have the same polarization axis as the second phase plate pattern templates 132 That is, the first device of glasses can transmit light of the image with the left circular polarization, blocking the light of the image with the right circular polarization, and the second device of glasses can transmit the light of the image with the right circular field polarization, blocking the image light from the left circularly polarized light. Accordingly, different viewers will be able to see images polarized in different ways. In the case of a 3D image, the left polarizing filter and the right polarizing filter of one eyeglass device have different polarization axes and can show images for the left eye and the right eye, respectively.

[220] Meanwhile, the template of the phase plate 132 may be configured to be electrically controlled to change the direction of polarization. In the exemplary embodiment described above, if it is necessary to see an image with right circular polarization by the first device of glasses and an image with left circular polarization by the second device of glasses, the display line pattern with an odd number and the display line pattern with an even number of the display device can be changed with each other .

[221] To accomplish this, for example, the phase plate template 132 may be implemented as a liquid cell. The orientation of the liquid cell changes in accordance with the exciting voltage, and the characteristics of the polarized light differ depending on the changed orientation. Here, the characteristics of polarized light may be the phase or direction of polarized light. That is, when polarized light enters and a specific exciting voltage is applied to the liquid cell to orient it, the wavelength of the incident light can be delayed. For example, a phase plate template 132 including a liquid cell may change the direction of circularly polarized light by changing the phase of circularly polarized light in an odd number display line or may change the direction of circularly polarized light by changing the phase of circularly polarized light in a row indications with an even number. Although the liquid cell is not limited in technical essence, if it is implemented as a twisted TN cell and the applied voltage is '0' (zero), the incident light rotates and the polarization direction can be changed by 90 degrees by twisting the liquid molecules. That is, if the incident light is polarized linearly, the direction of polarization is rotated 90 degrees, if the incident light is light with a left circular polarization, the direction of polarization changes towards the light with right circular polarization, and the light with right circular polarization changes towards the light from the left circular polarization.

[222] FIG. 21 illustrates a case where content is viewed by a device of glasses having a polarizing lens in accordance with a phase plate pattern method in accordance with an exemplary embodiment of the invention.

[223] In the above exemplary embodiment, the polarization axes of the patterns differ depending on each horizontal pixel row. However, any area of the pattern in the phase plate pattern does not have to be divided into vertical lines. That is, as shown in FIG. 21, the phase plate pattern may include third patterns that refer to odd-numbered lines for each vertical row, and fourth patterns that refer to even-numbered rows. Here, the polarizing filter of one device 200-11 points can have the same axis of polarization (horizontal direction) as the first templates of the phase plate template. In addition, the polarizing filter of another 200-12 points device may have the same polarization axis (vertical direction) as the second phase plate pattern templates. Each device points shows content 1 and content 2, respectively.

[224] FIG. 22 illustrates a case where content is viewed by a device of glasses having a polarizing lens in accordance with an active phase plate method, in accordance with an exemplary embodiment.

[225] Meanwhile, similar to the conversion of the patterns of the phase plate 132, the characteristics of the polarized light throughout the polarization panel can be changed. In particular, as described above, the characteristics of polarized light are subject to change whenever the image frame is changed, if the method described above for providing multiple presentation by alternately displaying image frames is implemented in a display device based on the method of polarizing light. To accomplish this, the display device may further include a polarizing element 190. The polarizing element may further include a liquid layer for polarizing the image. The display device 100 controls the liquid layer for each horizontal line or vertical line using an exciting voltage of various levels, and polarizes the content image output from the display device 100 in a specific direction. That is, as illustrated in FIG. 22, the direction of polarization changes by changing the characteristics of the polarized light of the polarizing panel when the image frame is displayed.

[226] In FIG. 22, if a horizontally polarized content view 2 is displayed, the content view 2 can be viewed by the device 200-11 points, but not by the device 200-12 points. When the content 1 is displayed, the display device 100 displays the displayed image by vertically polarizing the image, and the viewer who wears the device 200-12 points can watch the content 1.

[227] Essentially, if multiple contents are polarized differently for each frame before its output, content can be provided to the viewer without compromising resolution. However, in this case, the display device 100 should increase the frame rate of the display device 100 and provide a change in the axis of polarization of the gates of the glasses so that the glasses device can correspond to the display device 100. In the case of the above method of the phase plate pattern, it is not necessary to change the frame rate, and the user can view the image using the device of glasses without shutter glasses, but the resolution may be deteriorated.

Glasses device configuration

[228] The configuration and operation of the eyeglass device based on the light polarization method will be explained below. FIG. 23 is a block diagram of a configuration of a device 200 points based on a method of polarizing light in accordance with an exemplary embodiment. As shown in FIG. 23, the eyeglass device 200 ′ based on the light polarization method in accordance with various exemplary embodiments includes a front polarizer 251, a liquid cell 252, a rear polarizer 253, an input unit 254 (e.g., an input device) and a control unit 255 (e.g., a controller )

[229] As described above, the device 200 'points transfers the image if the image has the same axis of light as the image polarized in the display device, and blocks the image if the image crosses its axis at right angles. Accordingly, a user who wears the eyeglass device 200 ′ can selectively view the image.

[230] As an exemplary embodiment of the eyeglass device based on the method of polarizing light, an eyeglass device 200 ′ is provided having a fixed polarization tool or mechanism. That is, the lens has a predetermined axis of light, and only a polarized image compatible with a predetermined axis of light is transmitted through this lens. Such a device of glasses can be used both in a display device based on the aforementioned phase plate pattern method, and in a display device based on a method with a plurality of representations by alternately displaying image frames. Each device 200 'points does not require a separate synchronization operation with the display device, and thus, the device 200 points is extremely economical and has less flicker effect (flicker effect).

[231] However, if the user wants to see a polarized image corresponding to a different axis of light that is different from a predetermined axis of light, the user must wear a eyeglass device having a different axis of light or replace the polarizing lens. The user can see the polarized image by simply replacing the polarizing lens installed in the eyeglass device and inserting a new polarizing lens. However, depending on the polarization characteristics of the image, the user can manually replace the lenses each time.

[232] Accordingly, in another exemplary embodiment, the eyeglass device may include means or mechanism for changing the polarization characteristics of the lens. Below will be described a device glasses having such a tool or mechanism.

[233] In the above exemplary embodiment described with reference to FIG. 23, the eyeglass device may transmit an image that is polarized and output to the display device 100, and to do this, may include a front polarizer 251, a liquid cell 252, a rear polarizer 253, and an input unit 254.

[234] The front polarizer 251 has polarized light in the same direction as the image that is polarized and output to the display device 100, and transmits the image. For example, the display device 100 may output an image that is polarized in the horizontal direction, in which case, the polarizer 251 transmits only an image that is polarized in the horizontal direction. However, if the eyeglass device has a polarizer 251 that only transmits a vertical polarized image, the eyeglass device may not transmit an image that is polarized in the horizontal direction. The front polarizer 251 blocks another ambient light having a different axis of light, with the exception of the image, which is actually polarized in the display device 100.

[235] The liquid cell 252 is a component whose orientation changes in accordance with the exciting voltage, and changes the characteristics of polarized light in accordance with the changed orientation. The characteristics of polarized light may relate to the phase or direction of polarized light. That is, when polarized light enters and a specific exciting voltage is applied to the liquid cell to orient it, the wavelength of the incident light can be delayed. For example, the liquid cell may be an active phase plate, and the direction of polarization of the linearly polarized image may change in accordance with the specific applied voltage (phase change), or the direction of circular polarization may be changed by changing the phase of circular polarization. The polarization characteristics can be changed appropriately to transmit incident light (left or right) by opening the eyeglass device or to block incident light by closing the eyeglass device. As an exemplary embodiment, if voltage is not applied, the linear light can be rotated 90 degrees (phase difference is λ / 2), and if voltage is applied, the linear light can be transmitted without affecting the incident light.

[236] Although the liquid cell is not limited in technical essence, in an exemplary embodiment, it is implemented as a TN cell with electrically controlled birefringence (ECB) or as a TN cell with optical compensated bending (OCB) in an exemplary embodiment. If the liquid cell is implemented as a twisted TN cell and the applied voltage is zero, the incident light rotates and the direction of polarization can be changed by 90 degrees by twisting the liquid molecules. That is, if the incident light is polarized linearly, the direction of polarization is rotated 90 degrees, if the incident light is light with left circular polarization, the direction of polarization changes towards the light with right circular polarization, and the light with right circular polarization changes towards light left circular polarization.

[237] The back polarizer 253 is a component that depolarizes the image that the liquid cell transmits and transmits only the polarization element in the transverse direction with respect to the polarized light output by the display device. Accordingly, after the eyeglass device is opened, the polarized image of the display device must be in a state in which the image can pass through the rear polarizer 253, which is achieved by manipulating the liquid cell. On the other hand, if the shutters of the glasses are closed, the liquid cell must be transformed so that the polarized image output by the display device is perpendicular to the polarization axis of the rear polarizer 253.

[238] Turning to the operation of the device points. If the shutter is open, the image output from the display device and polarized in the vertical direction passes through the front polarizer 251, and the liquid cell 252 transmits the image and makes the polarization direction compatible with the polarization axis of the rear polarizer 253. Accordingly, the image reaches the human eye with the help of glasses . On the other hand, if the shutter is closed, the image output from the display device and polarized in the vertical direction passes through the front polarizer 251, and the liquid cell 252 also allows the image to pass through itself. Accordingly, the directions of polarization intersect at right angles, and thus the polarized image does not pass through the device of the glasses and does not reach the human eyes.

[239] The input unit 254 is a component by which the user enters a control command to control the liquid cell 252 of the display device. That is, the user can change the direction of polarization of the polarizing lens using electricity by manipulating the input unit 254. The input unit 254 may include a button, a touch panel, a switch, etc., to change the direction of polarization of the polarizing lens. For example, if a user who is watching content 2 using the device 200-11 points, presses a switch button to change the direction of polarization of the polarizing lens, the device 200-11 points changes the direction of polarization of the polarizing lens to vertical, and accordingly, the user can watch the content 1 .

[240] The control unit 255 controls all operations of the device 200 'points. In particular, the operation of the liquid cell 252 is controlled, as described above, in accordance with the input of the input unit 254.

[241] Here, the device 200-11, 200-12 points can change the direction of polarization of the lens of the left eye and the lens of the right eye, respectively. If the polarization directions of the left eye lens and the right eye lens become different from each other when the polarization direction of the left eye lens and the right eye lens changes, the eyeglass device can be used to view 3D content.

[242] In the case of a device for 3D display based on the method of polarizing light, many viewers are watching the same content and, thus, there is no need for communication between the display device 100 and the device 200 points. However, if each of the plurality of viewers is watching different content, the device 200 points communicates with the device 100 display. For example, glasses devices 200-11 and 200-12 may receive audio data corresponding to each content from the interface unit 160 of the display device 100 and output audio data via the audio output unit or may transmit a control command inputted by the input unit 254 to the display device 100 . To accomplish this, the device 200-11 and 200-12 points may additionally include an interface unit (for example, an interface) that connects to the display device 100 to communicate. Since the interface unit of the eyeglass device has already been described above with reference to FIG. 6, no further description will be provided.

[243] In the above exemplary embodiment, the polarization direction of the glasses device is changed to change the presentation of the content. However, instead of changing the direction of polarization of the polarizing lens in the glasses device, the content output by the display device can be changed.

For example, in FIG. 20, if a user who is watching content 1 using the device 200-11 glasses having a polarizing lens in the horizontal direction wants to watch content 2 by changing the presentation of the content, the display device 100 can output content 2 in the area where the content 1 was displayed, when a command to change the presentation of the content is entered using an input unit (e.g., an input device) in the remote control device 300 or in the device 200-11 points.

[244] Meanwhile, if the content is viewed using the device glasses, there may be a mode for providing multiple content and a mode for providing 3D content. If the device 200-11, 200-12 points can change the direction of polarization for each of the lenses of the left eye and the right eye, the display device 100 may display a message indicating that the user should change the direction of polarization for one of the lens of the left eye and the lens of the right eye. A user who wears a glasses device can change the direction of polarization by manipulating the input unit 254.

[245] If the eyeglass device cannot change the direction of polarization of each of the lenses of the left eye and the right eye, a message indicating that the user should change the device of the glasses may be displayed when the mode changes.

[246] Although the above exemplary embodiments relate to a display device 100 including a display unit 130, it is understood that other exemplary embodiments are not limited to this. For example, other exemplary embodiments may be applied to an image processing device, such as a television set-top box, a self-contained device, an audio / video receiver, an optical media player, a TV sensor, etc. In addition, it is understood that in exemplary embodiments, one or more of the units of the above devices 100, 200, 300 may include a processor or microprocessor executing a computer program stored on a computer-readable medium.
