Description

Glasses device, display device, content providing method using them and mode switching method of display device {GLASSES APPARATUS, DISPLAY APPARATUS, CONTENTS PROVIDING METHOD USING THE SAMES AND METHOD FOR DISPLAY APPARATUS MODE CONVERSION}

The present invention relates to a spectacle device, a display device, and a content providing method using the same. More particularly, the present invention relates to a spectacle device, a display device, and a content providing method using the same.

The present invention also relates to a display apparatus for performing mode switching in accordance with an operation state of the spectacle apparatus and a mode switching method thereof.

With the development of digital technology, various types of electronic products are being developed and distributed. In particular, various display devices such as TVs, mobile phones, PCs, notebook PCs, and PDAs are used in most households.

As the use of display devices has increased, the user needs for more diverse functions have also increased. Accordingly, the efforts of each electronic product manufacturer to meet the user needs has also increased, and products with new functions that have not existed in the past have appeared one after another.

In particular, in recent years, there is a high need for a technology that allows a plurality of users to view content desired by one common display device. Display devices are inherently challenging to show realistic images to viewers. For this purpose, the display device should be as large and clear as possible within the human field of view. It is for this reason that PCs, smartphones, etc., which correspond to personal display devices, are constantly solving the problem. However, since a personal display device presupposes portability, there is a limitation in size to provide a complete display. On the other hand, a public display device such as a TV or a large screen can overcome the limitations of the image transmission that a personal display device has, but it does not provide individualized contents to each viewer. Therefore, a technology for providing a clear image of content suitable for an individual among various contents is required through one common display device.

In order to use a common display device as a personal display device, various convergence technologies must be considered. That is, the expansion of the common display device as described above should be complete and to the extent that it can replace the function of the personal display device. To this end, the interface of the personal display device should be considered.

In the case of such a display device, since the user views only one desired content, there is a problem in that the content of the content viewed by another user cannot be checked. Accordingly, a search for a method for easily checking the contents of contents watched by other users by a simple operation is requested.

In addition, when the plurality of content views are output, a case in which the glasses device connected to any one content view is turned off may occur. In particular, in the case of outputting a plurality of content views alternately, the number of image frames of each content view is reduced by half compared to the case of outputting only one content view, and thus the display resolution is inferior. Therefore, a clear image cannot be viewed. . In addition, since image data for different content views must be received and image processed, power loss is inevitably high. Therefore, when one or more eyeglasses are turned off in a situation where a plurality of content views are output, the number of content views that are actually matched with the eyeglasses is reduced, so as to reduce the number of content views or switch to single view mode. It is necessary to do However, when different content views are output, a user who is watching one content view may have difficulty in knowing the viewing situation of another user, and thus the display device recognizes a decrease in the number of content views, There is a need for a mode switching operation to reduce the number or switch to single view mode.

The display apparatus 100 combines and displays a plurality of different contents, and each of the plurality of glasses apparatuses 200-1 and 200-2 transmits only one content image displayed by the display apparatus 100. Displaying a combination of content means mixing and composing content to form and display an image frame or displaying content alternately. The alternating display of a plurality of contents may be performed by alternately displaying a frame containing image information of one content and then displaying a frame containing image information of another content. This means displaying a frame containing information.

1 is a view for explaining a method of providing a plurality of 2D contents according to an embodiment of the present invention.

The display apparatus 100 alternately displays a plurality of 2D contents (contents A and B), and generates a synchronization signal for synchronizing the glasses apparatuses 1 and 2 200-1 and 200-2 corresponding to the respective contents. It transmits to eyeglasses 1 and 2 (200-1, 200-2).

In this case, the spectacle device 1 200-1 opens both the left shutter glass and the right shutter glass when one content A is displayed according to the synchronization signal, and the left shutter when the other content B is displayed. It may be operable to turn off both the glass and the right shutter glass. Accordingly, viewer 1 wearing eyeglass device 1 200-1 synchronizes one content (synchronized with eyeglass device 1 200-1) among a plurality of contents A and B that are alternately displayed. A) You can watch only. In the same manner, viewer 2 wearing the spectacles 2 200-2 may watch the content B only. The alternating display of image frames for different content is achieved at a very high speed, and the afterimage effect of the retina persists while the lens is closed, making the image appear natural to the user.

2 is a view for explaining a method of providing a plurality of 3D content according to an embodiment of the present invention.

As shown in the drawing, when the plurality of 3D contents (contents A and B) are 3D contents, the display apparatus 100 alternately displays the plurality of 3D contents (contents A and B), while the left eye image of each 3D content and The right eye image can also be displayed alternately.

For example, the left eye image and the right eye images AL and AR of the 3D content A may be displayed, and the left eye image and the right eye images BL and BR of the 3D content B may be alternately displayed. In this case, the eyeglass device 1 200-1 opens the left eye and the right eye glass at the display time point of the left eye image and the right eye image AL and AR of the 3D content A, and the eyeglass device 2 200-2 the 3D content B. The left eye and right eye glasses may be opened at the display time point of the left eye image and the right eye image BL and BR.

Accordingly, viewer 1 wearing the eyeglass device 1 200-1 views only the 3D content A, and viewer 2 wearing the eyeglass device 2 200-2 views the 3D content B only. You will watch.

However, this is a description of a case in which the shutter glass method is assumed, and in the case of the polarization method, the polarization direction of each of the plurality of content images and the polarization directions of the spectacles 1 and 2 may be implemented to support the multi-view mode. It will be apparent to those skilled in the art.

3 and 4 are diagrams for describing a synchronization signal transmission method according to various embodiments of the present disclosure.

According to FIG. 3, the display apparatus 100 may broadcast or multicast a single signal muxed with a synchronization signal corresponding to the spectacle apparatus 1 200-1 and the spectacle apparatus 2 200-2. The spectacle apparatuses 200-1 and 200-2 may operate to turn on / off the shutter glass in synchronization with a synchronization signal corresponding to a user command (eg, a channel switching command) among the corresponding signals.

However, the above-described embodiment is merely an example, and as shown in FIG. 4, the display apparatus 100 may provide a synchronization signal corresponding to the eyeglass apparatus 1 200-1 and the eyeglass apparatus 2 200-2. Each of the corresponding glasses apparatuses 200-1 and 200-2 may be unicasted, and the glasses apparatuses 200-1 and 200-2 may receive a corresponding synchronization signal.

Meanwhile, the synchronization signal may be implemented in the form of an RF (Radio Fequency) signal or an Infra Red (IR) signal, which will be described later.

5 is a block diagram illustrating a configuration of a display apparatus according to various embodiments of the present disclosure.

Referring to FIG. 5, the display apparatus 100 includes a plurality of receivers 110-1, 110-2,..., 110-n, and a plurality of signal processors 120-1, 120-2,. n), a display unit 130, a synchronization signal generator 140, an interface unit 150, and a controller 160.

The plurality of receivers 110-1, 110-2,..., 110-n receive different contents, respectively. In detail, each receiver 110-1, 110-2,..., 110-n stores contents from a broadcasting station transmitting broadcast program content using a broadcast network or a web server transmitting content files using the Internet. Receive. It is also possible to receive content from various recording medium playback apparatuses provided in the display apparatus 100 or connected to the display apparatus 100. [ The recording medium playback device refers to a device that plays back content stored in various types of recording media such as CD, DVD, hard disk, Blu-ray disk, memory card, USB memory,

In an embodiment of receiving content from a broadcasting station, the plurality of receivers 110-1, 110-2,..., 110-n may include a tuner (not shown), a demodulator (not shown), and an equalizer (not shown). It may be implemented in a form including a configuration such as. In contrast, in an embodiment of receiving content from a source such as a web server, the plurality of receivers 110-1, 110-2,..., 110-n may be implemented as a network interface card (not shown). . Alternatively, in the case of receiving the contents from the various recording medium reproducing apparatuses described above, the plurality of receiving units 110-1, 110-2,..., 110-n may include an interface unit (not shown) connected to the recording medium reproducing apparatus. May be implemented. For example, an AV terminal, a COMP terminal, and an HDMI terminal.

As such, the plurality of receivers 110-1, 110-2,..., 110-n may be implemented in various forms according to embodiments.

In addition, the plurality of receivers 110-1, 110-2,..., 110-n may not necessarily receive content from the same type of source, but may also receive content from different types of sources.

The plurality of signal processing units 130-1, 130-2,..., And 130-n respectively receive content received from the plurality of receivers 110-1, 110-2,..., 110-n. Various signal processing can be performed.

In particular, the plurality of signal processing units 130-1, 130-2,..., 130-n process each received image in the form of an image frame, and perform luminance adjustment processing for each of the plurality of contents processed in the form of a frame. Can be done.

Meanwhile, according to various embodiments of the present disclosure, the display apparatus 100 may further include a mux unit (not shown) for multiplexing image frames. The MUX unit 170 may multiplex and output the image frames such that the image frame of the first content, the image frame of the second content, ..., and the image frame of the n-th content are alternately arranged one by one.

The display 130 displays a plurality of contents according to the data output from the mux unit (not shown). Accordingly, the display 130 may be displayed in a form in which at least one image frame of each content is alternately arranged.

The display 130 outputs one content view in the single view mode and combines and outputs the plurality of content views in the multi view mode.

The display unit 130 may include a liquid crystal display panel, a plasma display panel, organic light emitting diodes (OLED), a vacuum fluorescence display (VFD), a field emission display (FED), and an ELD ( Electro Luminescence Display) and the like. The display unit 130 may be implemented in the form of a display unit as described below.

As described above, a mode of alternately arranging image frames of each content and displaying the same may be referred to as a multi view mode (or a dual view mode). When the display apparatus 100 operates in a normal mode (or a single view mode) displaying only one 2D content or 3D content, only one of the plurality of receivers 110-1, 110-2,..., 110-n is displayed. Can be activated to process content. When the user selects the multi-view mode while operating in the normal mode, the display apparatus 100 may activate the remaining receiver to process data in the above-described manner.

Meanwhile, the above-described content may be 2D content or 3D content. 3D content refers to content that allows a user to feel three-dimensional by using a multi-view image in which the same object is expressed from different perspectives.

When using a plurality of 3D contents, the display unit 130 includes a left eye image and a right eye included in each 3D content provided by the plurality of frame rate converters 122-1, 122-2, ..., 122-n. Images may be multiplexed in a predetermined arrangement and alternately arranged with image frames of other contents.

Accordingly, the left eye image, the right eye image of the first content, the left eye image of the second content, the right eye image, the left eye image of the n-th content, and the right eye image are sequentially arranged and displayed, and the user displays the eyeglasses 200. Through this, the left eye image and the right eye image of one content are recognized.

Meanwhile, the display apparatus 100 further includes a configuration for differently providing audio data included in each content for each user when operating in the multi-view mode. That is, a demultiplexer (not shown) for separating video data and audio data from content received at each receiver 110-1, 110-2,..., 110-n, and an audio decoder for decoding the separated audio data. (Not shown), a modulator (not shown) for modulating the decoded audio data into different frequency signals, a display unit (not shown) for transmitting the modulated audio data to the spectacles, and the like. Each audio data output from the display unit 130 is provided to the user through output means such as earphones provided in the spectacles. Since these configurations are not directly related to the present invention, a separate illustration is omitted.

In some cases, if the content includes additional information such as an EPG (Electronic Program Guide) and subtitles, the demultiplexer may further separate the additional data from the content. In addition, the display apparatus 100 may add a subtitle or the like processed to be displayed through an additional data processor (not shown) to the corresponding image frame.

The synchronization signal generator 140 generates a synchronization signal for synchronizing the glasses device corresponding to each content according to the display timing of each content. That is, the synchronization signal generator 140 generates a synchronization signal for synchronizing the spectacles with the display timing of the image frame for the content in the multi-view mode.

The interface unit 150 transmits a synchronization signal to the spectacles. In this case, the interface unit 150 may transmit the synchronization signal to the spectacles device in various ways.

For example, the interface unit 150 may include an RF communication module to communicate with at least one glasses device. Herein, the RF communication module may be implemented as a Bluetooth communication module. Accordingly, the interface unit 150 may generate a transmission stream according to the Bluetooth communication standard so as to include a synchronization signal and transmit the generated stream to the spectacles.

That is, the transport stream includes time information for turning on / off the shutter glass of the spectacle device in synchronization with the display timing of each content. Specifically, the transport stream includes an offset time for turning on the left eye shutter glass of the spectacle apparatus, an offset time for turning off the left eye shutter glass, an offset time for turning on the right eye shutter glass, and a right eye shutter glass from a reference time point set for each content. It may include information about the offset time to turn off. Here, the reference time point is a time point at which the vertical sync signal is generated in the image frame of each content, and time information on the time point at which the vertical sync signal is generated may also be included in the transport stream.

In order to perform communication according to the Bluetooth communication method, the interface unit 150 performs pairing with each eyeglass device. When pairing is completed, information about each eyeglass device, for example, a device ID (or address), may be registered in the interface unit 150. The interface unit 150 matches a display timing of each content with information about the glasses device and generates one transport stream according to the Bluetooth communication standard. For example, the interface unit 150 may match information about different glasses devices for each content in the order in which the image frames of the content are arranged. That is, when two contents are alternately provided in the multi-view mode, the image frames of the first, third, ..., n-th placed images match the information about the first glasses device, and the second For example, the fourth,..., N + 1 th image frame may match information about the second eyeglass device (where n is odd). The eyeglasses may check the display timing corresponding to the eyeglass apparatus information when the synchronization signal is received, and turn the shutter glass on or off according to the confirmed display timing.

In one embodiment, the interface unit 160 may have a plurality of Bluetooth addresses, and one eyeglass device may be connected to one Bluetooth address. At this time, according to the order in which the spectacles 200 are connected to the interface unit 160, the Bluetooth address may be given to each spectacles in an ascending or descending order. The interface unit 160 may be set to be excluded from the Bluetooth address search target in order to prevent the other glasses device from being connected to the Bluetooth address used for the connection with the eyeglass device 200.

Although the above-described embodiment has been described as the interface unit 150 and the spectacle device performing communication according to the Bluetooth communication method, this is only an example. That is, in addition to the Bluetooth method, it is possible to use a communication method such as infrared communication, Zigbee, etc., and to perform communication according to various wireless communication methods capable of transmitting and receiving signals by forming a communication channel in other local areas. .

The interface unit 150 may provide an IR (Infra Red) synchronization signal having a different frequency to the spectacle device. In this case, the spectacle apparatus may receive a synchronization signal having a specific frequency and turn on or off the shutter glass according to the display timing of the corresponding content.

In this case, the interface unit 150 glasses the infrared signal in which the high level during the first period and the low level during the second period are alternately repeated at predetermined time intervals based on the synchronization information. Can be sent to the device. The spectacle device may be implemented to turn on the shutter glass during the first period at the high level and to turn off the shutter glass during the second period at the low level. In addition, the synchronization signal may be generated in various ways.

Although the interface unit 150 has been described as performing communication with a plurality of eyeglasses as one communication module, the interface unit 150 may be implemented as a plurality of communication modules which individually communicate with each eyeglass device. Alternatively, when the display apparatus 100 supports a plurality of wireless communication methods, the interface unit 160 may be implemented to include a plurality of communication modules according to different wireless communication methods. The wireless communication method is the same as the above-described embodiment.

The controller 160 controls operations of the first half of the display apparatus 100. Specifically, the controller 160 includes a plurality of receivers 110-1, 110-2,..., 110-n, and a plurality of signal processors 130-1, 130-2,..., 130-n. Each control unit may be controlled to perform a corresponding operation by controlling each of the MUX unit (not shown), the display unit 130, the synchronization signal generator 140, and the interface unit 150. On the other hand, since the operation performed by each configuration of the display apparatus 100 has been described above, duplicate description thereof will be omitted.

6 is a block diagram showing the configuration of the signal processor 130.

Referring to FIG. 6, the arbitrary signal processor 120-1 may include a video processor 121-1 and a frame rate converter 122-1.

The video processor 121-1 performs signal processing on video data included in the received content. In detail, the video processor 121-1 may include a decoder (not shown) that performs decoding on video data, and a scaler (not shown) that performs up or down scaling in accordance with the screen size of the display 130. Can be.

In addition, the video processor 121-1 may convert the video data into a data format corresponding to the frame rate converter 122-1. For example, image frames of respective contents may be connected in a horizontal direction to be converted into a side-by-side format.

The frame rate converter 122-1 converts the frame rate of the content provided from the video processor 121-1 to match the multi-content display rate with reference to the output rate of the display apparatus 100. In detail, when the display apparatus 100 operates at 60 Hz, the frame rate converter 122-1 may convert the frame rate of each content to n × 60 Hz.

The communication interface 210 receives a synchronization signal from the display device.

For example, when the communication interface 210 is implemented as a Bluetooth communication module, communication with the display apparatus 100 according to a Bluetooth communication standard may be performed to receive a transport stream including a synchronization signal. In this case, the transport stream includes time information for turning on or off the first shutter glass unit 250 and the second shutter glass unit 260 of the spectacles 200 in synchronization with the display timing of each content. The apparatus 200 may turn on or off the shutter glasses according to the display timing corresponding to the glasses device.

Unlike this, the communication interface 210 may be implemented as an IR receiving module to receive an infrared signal having a specific frequency. In this case, time information for turning on or off the first shutter glass unit 250 and the second shutter glass unit 260 of the spectacles 200 to be synchronized with the display timing of one of the plurality of contents is included. do.

Meanwhile, the communication interface 210 may receive information about an image frame rate and an image frame period for each content from the display apparatus 100.

The controller 220 controls the operation of the first half of the spectacles 200. In particular, the controller 220 transfers the synchronization signal received from the communication interface unit 210 to the shutter glass driver 230 to control the operation of the shutter glass driver 230. That is, the controller 220 controls the shutter glass driver 230 to generate driving signals for driving the first shutter glass unit 250 and the second shutter glass unit 260 based on the synchronization signal.

The shutter glass driver 230 generates a driving signal based on the synchronization signal received from the controller 220. In particular, the shutter glass driver 230 may include the first shutter glass unit 250 and the second shutter glass unit based on a display timing of one of a plurality of contents displayed on the display apparatus 100 based on the synchronization signal. 260 may be opened.

The first shutter glass unit 250 and the second shutter glass unit 260 turn on or off the shutter glass according to a driving signal received from the shutter glass driver 230. Specifically, the first shutter glass unit 250 and the second shutter glass unit 260 simultaneously open the shutter glass when one of the plurality of contents is displayed, and turn off all of the shutter glasses when the other contents are displayed. Let's do it. Accordingly, a user wearing the spectacles 200 may view one content.

In the case of 3D content, the first shutter glass unit 250 and the second shutter glass unit 260 may alternately open and close the respective glasses. That is, the first shutter glass unit 250 may be opened at the timing when the left eye image constituting one 3D content is displayed according to the driving signal, and the second shutter glass unit 260 may be opened at the timing when the right eye image is displayed. Can be.

Not paired  Other content View  Embodiments that can be synchronized

Hereinafter, according to various embodiments of the present disclosure, an eyeglass device, a display device, and a content providing method using the same may be synchronized with another content view that is not currently paired.

Subsequently, a description will be given with reference to FIG. 5.

The controller 160 controls the operation of the first half of the display apparatus 100 as described above. In particular, the controller 160 may control the communication module to transmit a synchronization signal by performing a connection operation with the glasses device according to a user command received from the glasses device. Here, the user command may be a pairing request message.

In detail, the controller 160 may control each Bluetooth communication module to transmit a synchronization signal by performing pairing with the Bluetooth communication module included in the glasses device according to a user command.

That is, the controller 160 broadcasts an Inquiry Message through the Bluetooth communication module, and searches for the glasses device within a range capable of Bluetooth communication. When the pairing request message is received in response to the query message from the eyeglass device, the controller 160 may transmit and receive a Bluetooth device address and a pin code with the eyeglass device to perform pairing. Here, the controller 160 may automatically perform pairing by registering the eyeglasses by automatically inputting the user without inputting the pin code directly. However, the present invention is not limited thereto, and the user may perform the pairing process by directly inputting pin codes of the display device and the eyeglass device.

In this case, the controller 160 may control the Bluetooth communication module provided in the interface unit 150 to perform the pairing operation with the different glasses devices. Here, since the Bluetooth communication module transmits different synchronization signals to the plurality of pairs of paired glasses devices, the display device 100 may synchronize different pairs of glasses to each of the plurality of contents. However, this is only an example, and the display apparatus 100 may include a plurality of Bluetooth communication modules, and the controller 160 controls each of the plurality of Bluetooth communication modules to perform a pairing operation with a plurality of eyeglasses. You can also control it.

Meanwhile, when a user command is received while the communication module is connected to the glasses device, the controller 160 may control the communication module to transmit a different synchronization signal by performing a connection operation with the glasses device. Specifically, when the pairing request message is received from the paired glasses device with the Bluetooth communication module, the controller 160 may release the connection with the paired Bluetooth communication module. The spectacle device may newly receive a synchronization signal different from the synchronization signal received from the Bluetooth communication module from the Bluetooth communication module. Accordingly, a user wearing the spectacles can watch other contents.

Meanwhile, in the above-described embodiment, the display apparatus 100 generates synchronization signals corresponding to the display timing of the contents, and transmits them to the glasses apparatus 200. However, this is merely an example.

That is, the controller 160 may control the interface unit 150 to generate a synchronization signal corresponding to the display timing of each content as one transport packet according to the Bluetooth communication standard. That is, the interface unit 150 synchronizes the display timing of the first content to open / off the shutter glass of the spectacles device, and synchronizes the display of the second content to open / off the shutter glasses of the spectacles device. Time information, ..., and one transmission packet including all the time information for opening / off the shutter glass of the spectacle device in synchronization with the display timing of the n-th content.

In this case, the interface unit 150 may generate a transport packet by matching the information on the spectacles with the display timing of each content. For example, the interface unit 150 may match information about different glasses devices for each content in the order in which the image frames of the content are arranged. That is, when two pieces of content are provided in the multi-view mode, the image frames of the first, third, ..., n-th placed images match information about the spectacle device 1, and the second, fourth, ...., the image frame of the content placed in the n + 1 th can match the information for the eyeglasses device 2 (where n is odd). In addition, the interface unit 150 may transmit a transmission packet generated to include a synchronization signal for each of the plurality of contents to the spectacles. The spectacle device may open / off the shutter glass by using a synchronization signal including its spectacle device information among the synchronization signals for each of the plurality of contents.

8 is a block diagram illustrating a configuration of an eyeglass device according to an embodiment of the present invention. According to FIG. 8, the spectacles 200 includes a communication interface 210, an inputter 240, and a controller 220. The spectacles 200 may interlock with a display device that alternately displays a plurality of contents.

The communication interface 210 communicates with the display device. In detail, the communication interface unit 210 communicates with the display apparatus according to various wireless methods, and receives a synchronization signal from the display apparatus.

For example, the communication interface unit 210 may include a Bluetooth communication module to communicate with a Bluetooth communication module in a display device and receive a synchronization signal having a transmission packet form according to the Bluetooth communication standard. Here, the transport packet according to the Bluetooth communication standard may include time information for synchronizing with the display timing of the content. Since the information contained in the transport packet has been described above, the redundant description is omitted.

The input unit 240 receives a user command for performing a connection operation with a plurality of communication modules included in the display device. To this end, the input unit 240 may include a switching button implemented as a touch sensor or an operation button.

The controller 220 controls the overall operation of the spectacles 200. In particular, when a user command is input, the controller 220 may control the communication interface 210 to perform a connection operation with the communication module included in the display apparatus to receive a synchronization signal corresponding to one of the plurality of contents. .

For example, the controller 220 transmits a pairing request message through a Bluetooth communication module provided in the communication interface unit 210, and transmits / receives a Bluetooth address and a pin code with a Bluetooth communication module provided in the display device to perform pairing. can do. When the pairing is completed, the controller 220 may receive a transport packet according to a Bluetooth communication standard including time information for synchronizing with the display timing of the content through the communication interface 210.

In this case, the controller 220 may pair the Bluetooth communication module included in the display device through different channels according to the number of times the user touches the switching button provided in the input unit 240. For example, when the user touches the switching button once, the controller 220 performs pairing with the first channel of the Bluetooth communication module included in the display device, and when the user touches the switching button twice, the display device is provided in the display device. The communication interface 210 may be controlled to perform pairing with the second channel of the Bluetooth communication module.

Meanwhile, the input unit 240 may include a plurality of switching buttons for receiving a user command for connecting to a communication module provided in the display device. In this case, the controller 220 may perform pairing with each channel of the Bluetooth communication module included in the display device whenever the plurality of switching buttons are touched in order to receive synchronization signals corresponding to different contents. The Bluetooth communication module included in the 210 may be controlled.

For example, when the user touches the switching button 1, the controller 220 performs pairing with the first channel of the Bluetooth communication module included in the display device, and when the user touches the switching button 2, the Bluetooth communication device included in the display device. The communication interface 210 may be controlled to perform pairing with the second channel of the module.

When the user inputs a selection command for selecting one of the plurality of content views to the input unit 240, the interface unit 210 transmits information about the selected content view to the display apparatus 100, and displays the display apparatus 100. A synchronization signal corresponding to the selected content view may be received from the.

Meanwhile, when a user command is input while the controller 220 is connected to the communication module and receives a synchronization signal corresponding to one of the plurality of contents, the controller 220 performs a connection operation with another channel of the communication module to perform the other one of the plurality of contents. The communication interface 210 may be controlled to receive the synchronization signal corresponding to the communication interface.

Specifically, the controller 220 transmits a pairing request message to the display device when a user command is input while pairing with the Bluetooth communication module included in the display device is completed. Accordingly, the controller 220 transmits / receives a Bluetooth address, a pin code, etc. from another display channel among the channels of the Bluetooth communication module, so that the Bluetooth communication module provided in the communication interface 210 is connected to another Bluetooth communication module of the display device. Can be controlled to perform pairing with another channel. Accordingly, a synchronization signal corresponding to another content among a plurality of contents can be received from another Bluetooth communication channel of the display device, so that a user wearing the glasses device can view other contents.

9 is a flowchart illustrating a detailed configuration of an eyeglass device according to an embodiment of the present invention. According to FIG. 9, the spectacle device 200 may include a communication interface 210, an input unit 240, a controller 220, a shutter glass driver 230, a first shutter glass unit 250, and a second shutter glass unit ( 260). Before describing FIG. 9, a configuration having the same reference numerals as in FIG. 8 performs the same function, and thus redundant description will be omitted. In addition, the description of the configuration of the above-described spectacle apparatus 200 except for the contents described below among the respective components. However, parts necessary for the understanding of the present embodiment will be redundantly described.

As described above, the controller 220 transfers the synchronization signal received from the communication interface unit 210 to the shutter glass driver 230 to control the operation of the shutter glass driver 230.

The shutter glass driver 230 generates a driving signal based on the synchronization signal received from the controller 220 as described above. In detail, the shutter glass driver 230 may include the first shutter glass unit 250 and the second shutter glass unit 260 according to the display timing of one of the plurality of contents based on the synchronization signal received from the display apparatus. Open

On the other hand, when the communication interface 210 is disconnected from any one channel of the communication module provided in the display device and connected to another channel, the control unit 220 is connected to the synchronization signal received from the other communication channel connected to enable communication. The shutter glass driver 230 is controlled to generate a driving signal based on the driving signal. Accordingly, the shutter glass driver 230 based on the newly received synchronization signal, the first shutter glass unit 250 and the second shutter glass in accordance with the display timing of the other of the plurality of contents displayed on the display device. The unit 260 may be opened.

The first shutter glass unit 250 and the second shutter glass unit 260 open or off the shutter glass according to a driving signal received from the shutter glass driver 230. Specifically, the first shutter glass unit 250 and the second shutter glass unit 260 simultaneously open the shutter glass when one of the plurality of contents is displayed, and turn off all of the shutter glasses when the other contents are displayed. Let's do it. Accordingly, a user wearing the spectacles 200 may view one content.

Meanwhile, in the above-described exemplary embodiment, the display apparatuses generate synchronization signals corresponding to the display timing of the contents, and transmit the generated synchronization signals to the spectacles 200, but this is merely an example. That is, the display device may generate a transmission signal corresponding to the display timing of each content as one transport packet according to the Bluetooth communication standard and transmit the same to the eyeglasses device.

When the synchronization signal is received, the controller 220 may check a display timing corresponding to the glasses device information and open or turn off the shutter glass according to the confirmed display timing. When the user command is input, the controller 220 may control to open / off the shutter glass according to the display timing of the content that does not match the glasses device information, thereby providing the user with other contents.

10 is a flowchart illustrating a content providing method of a display apparatus according to an exemplary embodiment.

First, a plurality of different contents are displayed (S1010). Specifically, a plurality of different contents are alternately arranged and displayed.

Thereafter, a synchronization signal is generated (S1020). Specifically, a synchronization signal for synchronizing the spectacles device corresponding to each content is generated according to the display timing of each content.

In operation S1030, the glasses and the glasses are connected. Specifically, the connection operation of any one channel of the communication module and the spectacles is performed according to a user command received from the spectacles. In this case, the communication module may be a Bluetooth communication module, and the Bluetooth communication module may perform pairing with the Bluetooth communication module provided in the glasses device according to a user command.

Then, the synchronization signal is transmitted (S1040). In detail, the synchronization signal may be transmitted using the communication module in which the connection operation is completed.

Meanwhile, in operation S1030, when a user command is received while the communication module is connected to the glasses device, the connection operation between the glasses and the other channel of the communication module may be performed to transmit different synchronization signals.

11 is a flowchart illustrating a content providing method of an eyeglass device according to an exemplary embodiment. In particular, FIG. 11 illustrates a content providing method of a spectacle device interlocked with a display device that alternately displays a plurality of contents.

First, a user command is input (S1110). Specifically, a user command for performing a connection operation with the communication module included in the display device is received.

Thereafter, if a user command is input (S1110-Y), the connection operation is performed (S1120). That is, the connection operation is performed through one channel of the communication module.

In operation S1130, a synchronization signal is received. In detail, when the connection operation is performed, a synchronization signal corresponding to one of the plurality of contents may be received.

On the other hand, the communication module provided in the display device is a Bluetooth communication module, the glasses device may communicate with the communication module provided in the display device using the Bluetooth communication module. In this case, in operation S1120, in order to receive a synchronization signal corresponding to one of the plurality of contents when a user command is input, the Bluetooth communication module may be controlled to perform pairing with one channel of the Bluetooth communication module.

In addition, the glasses device may include a plurality of switching buttons for receiving a user command for a connection operation with the communication module. In this case, in step S1120, whenever the plurality of switching buttons are touched, the Bluetooth communication module may be controlled to perform a pairing operation with the Bluetooth communication module included in the display device.

Meanwhile, in operation S1120, when a user command is input while connected to one channel of the communication module, the operation may be performed through another channel of the communication module to receive a synchronization signal corresponding to another one of the plurality of contents. .

Meanwhile, the content providing method according to the present embodiment may open the first and second shutter glasses in accordance with the display timing of one of the plurality of contents based on the synchronization signal received from the display apparatus.

Since each embodiment of FIG. 10 and FIG. 11 has been described above, overlapping description thereof will be omitted.

Meanwhile, the program for performing the method according to various embodiments of the present disclosure described above may be stored and used in various types of recording media.

Specifically, the code for performing the above-described methods may be stored in a storage medium such as a RAM (Random Access Memory), a FLASH memory, a ROM (Read Only Memory), an EPROM (Erasable Programmable ROM), an EEPROM (Electronically Erasable and Programmable ROM) Such as a floppy disk, a removable disk, a memory card, a USB memory, a CD-ROM, and the like.

According to the operating condition of the spectacles mode  Example of performing a switchover

Hereinafter, a display apparatus and a mode switching method of the display apparatus for performing mode switching according to an operation state of each of the plurality of eyeglasses according to various embodiments of the present disclosure will be described.

12 is a conceptual diagram illustrating an output of the display apparatus 100 when one content view of the display apparatus 100 is turned off.

However, in a situation in which a plurality of content views are output, a case in which the spectacle device 200 connected to any one content view is turned off. For example, as shown in FIG. 12, one of two glasses apparatuses 200 matched to two different content views may be turned off. In this case, if there is no other glasses device 200 matched with the content view 2, since only the content view 1 matches the glasses device 200-2, the display device 100 also does not need to output a plurality of content views. . In particular, in the case of outputting a plurality of content views alternately, the number of image frames of each content view is reduced by half compared to the case of outputting only one content view, and thus the display resolution is inferior. Therefore, a clear image cannot be viewed. . In addition, since image data for different content views must be received and image processed, power loss is inevitably high. Therefore, when the number of content views actually matched with the eyeglasses 200 is reduced by turning off one or more eyeglasses 200 in a situation where a plurality of content views are output, the number of content views is reduced or a single view is reduced. You need to do a mode switch to switch to mode. However, when different content views are output, the user viewing one content view is difficult to know about the viewing situation of another user, and thus the display apparatus 100 recognizes that the number of content views is reduced and is output. It should be possible to perform mode switching operation to reduce the number of content views or switch to single view mode.

Hereinafter, a detailed configuration and operation of the display apparatus 100 and the spectacles 200 according to an exemplary embodiment of the present disclosure will be described in detail.

As shown in FIG. 5, the display apparatus 100 according to various embodiments of the present disclosure may include a plurality of receivers 110-1, 110-2,..., 110-n, and a plurality of signal processor 120-1. 120-2,..., 120-n), a display unit 130, a synchronization signal generator 140, an interface unit 150, and a controller 160.

In addition to the contents described below, the components are in accordance with the above-described embodiments, and in the following, the overlapping contents will be omitted as much as possible, but the overlapping contents will be described as necessary to help the understanding of the present embodiment.

The synchronization signal generation unit 140 generates a synchronization signal for synchronizing the glasses apparatus 200 corresponding to each content according to the display timing of each content. In particular, when there is a change in the number of content views due to a mode change of the display apparatus 100 as described below, a synchronization signal is generated according to the number of newly changed content views.

The interface unit 150 communicates with the spectacles 200. In this case, the communication interface unit 150 may communicate with the spectacle apparatus 200 according to various wireless methods to transmit a synchronization signal to the spectacle apparatus 200 or may be paired with the spectacle apparatus 200.

For example, the communication interface unit 150 may be provided with a Bluetooth communication module to communicate with the glasses device 200, and generate a synchronization signal as a transport stream according to the Bluetooth communication standard to transmit the glasses to the glasses device 200. .

If there is a change in the number of content views and there is a mode change of the display apparatus 100, the on / off offset time of the shutter glass of the spectacle apparatus 200 is newly set and transmitted according to the synchronization signal matched to the changed content view. The stream will contain this information.

The control unit 160 will be described below. As described above, the controller 160 controls the overall operation of the display apparatus 100. In particular, the controller 160 may perform mode switching according to an operation state of each of the plurality of eyeglasses 200. For example, one or more eyeglasses 200 of the plurality of eyeglasses 200 may be turned off to leave only one content view matched with the eyeglasses 200. In this case, since viewing is performed only through one content view, it is not different from the single view mode, but the display apparatus 100 still outputs a plurality of content views alternately. Therefore, as described above, the power loss is large, and since the display resolution is lower than that of the single view mode, a clear screen cannot be viewed. In this case, the controller 160 recognizes that the one or more eyeglasses 200 are turned off, and accordingly switches the display apparatus 100 to the single view mode. As another example, one or more eyeglasses 200 of the plurality of eyeglasses 200 may be turned off to reduce the number of content views matched with the eyeglasses 200. In this case, since the number of content views output through the display apparatus 100 is larger than the number of content views actually viewed, power loss and low resolution problems occur as described above. Therefore, when the one or more eyeglasses 200 are turned off and the number of content views is reduced, the controller switches the display apparatus 100 to the multi-view mode corresponding to the number of remaining content views. As another example, when the one or more eyeglasses 200 change the matched content view, the total number of content views matched with the eyeglasses 200 may change. For example, a glasses device 200 is matched with a content view that broadcasts a sports program, and the user changes the content view to a content view that broadcasts a drama, and the other glasses device 200 matched with a content view that broadcasts a sports program. If is not present, the number of content views matched with the spectacles 200 is reduced. In this case, the controller 160 switches the display apparatus 100 to the multi-view mode corresponding to the number of remaining content views. Similarly, when the number of content views matched with the spectacles 200 is reduced and only one is left, the controller 160 switches the display apparatus 100 to the single view mode. FIG. 15 illustrates a situation in which the display apparatus 100 is thus switched to the single view mode when one glasses apparatus 200-1 is turned off when the number of content views is two.

In order to change the mode, the display apparatus 100 should receive information about an operation state of the spectacle apparatus 200 from the spectacle apparatus 200. When a turn-off command is input through the input unit 240 of the spectacle apparatus 200, the spectacle apparatus 200 displays that the power of the spectacle apparatus 200 is turned off through the communication interface 210. The device 100 may be informed. Then, the interface unit 150 of the display apparatus 100 receives the turn-off input from the spectacle apparatus 200 and terminates the matching of the contents view with the spectacle apparatus 200. Similarly, the case where the content view matched with the spectacles 200 is changed. That is, a command for changing the content view may be input through the input unit 240 of the spectacle apparatus 200 which will be described later, and the spectacle apparatus 200 may view the content view of the spectacle apparatus 200 through the communication interface 210. Informs the display apparatus 100 that is changed. The interface unit 150 of the display apparatus 100 receives a change command input of a content view from the glasses apparatus 200.

Hereinafter, a mode switching method will be described.

13 and 14 are flowcharts illustrating a mode switching method of a display apparatus according to various embodiments of the present disclosure.

First, a plurality of contents are received (S1305 and S1405), and a plurality of contents are respectively processed to form an image frame (S1310 and S1410). Thereafter, the plurality of content views are output by combining the image frames of the respective contents (S1315 and S1415), and a synchronization signal for synchronizing the plurality of content views and the plurality of eyeglasses is generated (S1320 and S1420). Then, the synchronization signal is transmitted to the plurality of spectacles (S1325, S1425). When the operation state of the spectacle device is changed in a situation in which a plurality of content views are output (S1330-Y, S1430-Y), when the display is switched from the multi view mode to the single view mode (S1435-Y), the display apparatus 100 Switch to single view mode (S1440). Accordingly, the content is received and signal-processed according to the single view mode (S1450, S1455, S1460, and S1465). If the multi-view mode is switched to another multi-view mode in which the number of content views is reduced (S1435-N), the multi-view mode corresponding to the number of remaining content views is switched (S1445).

Meanwhile, when the spectacle apparatus is turned on again while being switched to the single view mode, the step of switching to the multi view mode may be further included.

Hereinafter, the eyeglass device 200 according to various embodiments of the present disclosure will be described.

16 is a block diagram illustrating a configuration of an eyeglass device 200 according to various embodiments of the present disclosure. In particular, the spectacle apparatus 200 of FIG. 16 is interlocked with the display apparatus 100 that alternately outputs a plurality of contents in an image frame unit, and includes an input unit 240, a controller 220, a shutter glass driver 230, The communication interface unit 210 includes a first shutter glass unit 250 and a second shutter glass unit 260.

The input unit 240 is configured to receive a turn-on command, a turn-off command, or a content view change command of the spectacle apparatus 200. The input unit 240 of the eyeglass apparatus 200 that matches one of the plurality of content views receives a turn-on command, a turn-off command, or a content view change command, and the communication interface 210 receives a display device ( 100). In the case of the turn-on command, the spectacle apparatus 200 may be turned on, and the mode of the display apparatus 100 may change according to the selection of the content view. When the turn-off command is input, the spectacles 200 is powered off, and the display apparatus 100 detects whether there is a change in the number of content views matched with the spectacles and changes the mode when there is a change. When a content view change command is input, the content view of the eyeglasses 200 is changed, and the display apparatus 100 detects whether there is a change in the number of content views matched with the eyeglasses, and switches modes when there is a change. . However, the turn-on command, the turn-off command, or the content view change command may not be input only through the input unit 240, but may be input through a separate device such as a remote controller.

The communication interface 210 performs communication from the display apparatus 100. The communication interface 210 is implemented as a Bluetooth communication module to communicate with the display apparatus 100 to receive a synchronization signal, and as described above, the turn-on command, the turn-off command, or the input signal through the input unit 240. The content view change command may be transmitted to the display apparatus 100.

As described above, the synchronization signal may be received in the form of a transport stream according to the Bluetooth communication standard, and synchronized to the display timing of the content, the first shutter glass unit 250 and the second shutter glass unit ( 260 may include time information for turning on or off. Since the information included in the transport stream has been described above, the redundant description is omitted.

The controller 220 controls the operation of the first half of the spectacles 200. In particular, the controller 220 transfers the synchronization signal received from the communication interface unit 210 to the shutter glass driver 230 to control the operation of the shutter glass driver 230. That is, the controller 220 controls the shutter glass driver 230 to generate driving signals for driving the first shutter glass unit 250 and the second shutter glass unit 260 based on the synchronization signal. In addition, the communication interface 210 may be controlled to transmit a turn-on command, a turn-off command, or a content view change command input through the input unit 24 to the display apparatus 100. In particular, when there is a mode change of the display apparatus 100, the spectacle apparatus 200 of the spectacle apparatus 200 according to the on / off offset time of the changed shutter glass of the spectacle apparatus 200 included in the transport stream received from the display apparatus 100. Control the shutter glass to be on or off.

The shutter glass driver 230 generates a driving signal based on the synchronization signal received from the controller 220. In particular, the shutter glass driver 230 may include the first shutter glass unit 250 and the second shutter glass unit based on a display timing of one of a plurality of contents displayed on the display apparatus 100 based on the synchronization signal. 260 may be opened.

The first shutter glass unit 250 and the second shutter glass unit 260 turn on or off the shutter glass according to a driving signal received from the shutter glass driver 230. Specifically, the first shutter glass unit 250 and the second shutter glass unit 260 simultaneously open the shutter glass when one of the plurality of contents is displayed, and turn off all of the shutter glasses when the other contents are displayed. Let's do it. Accordingly, a user wearing the spectacles 200 may view one content.

Meanwhile, in the above-described embodiment, the display apparatus 100 generates synchronization signals corresponding to the display timing of the contents, and transmits them to the glasses apparatus 200. However, this is merely an example.

When the synchronization signal is received, the spectacle apparatus 200 may check the display timing corresponding to the information of the spectacle apparatus 200 and turn on or off the shutter glass according to the confirmed display timing. That is, the spectacles 200 may control the shutter glass driver 230 to sequentially generate driving signals based on synchronization signals corresponding to each content included in the transport stream. Accordingly, the first shutter glass unit 250 and the second shutter glass unit 260 are opened whenever an image frame of each content is displayed.

Meanwhile, the program for performing the method according to various embodiments of the present disclosure described above may be stored and used in various types of recording media.

Specifically, the code for performing the above-described methods may be stored in a storage medium such as a RAM (Random Access Memory), a FLASH memory, a ROM (Read Only Memory), an EPROM (Erasable Programmable ROM), an EEPROM (Electronically Erasable and Programmable ROM) Such as a floppy disk, a removable disk, a memory card, a USB memory, a CD-ROM, and the like.

FIG. 17 is a diagram illustrating an example of a system capable of viewing a polarized image, FIG. 18 is a diagram illustrating a pattern retarder method, and FIG. 19 is a diagram illustrating another embodiment of the pattern retarder method. 20 is a diagram illustrating an embodiment of a multi-view method using an alternate display of an image frame.

As shown in FIG. 17, a system capable of viewing a polarized image includes a display device 100 and an eyeglass device.

The display apparatus 100 is configured to output an image, and outputs an image polarized in a specific direction such as a horizontal direction or a vertical direction. As shown in FIG. 17, when the display device outputs an image polarized in the vertical direction A, the spectacle device 40 may pass only the image polarized in the horizontal direction B, and block the image polarized in the vertical direction A. FIG. In this case, the viewer wearing the glasses cannot watch the image polarized in the vertical direction. As such, since the display apparatus 100 must polarize the output image, the display apparatus 100 includes various polarization means.

According to an embodiment of the polarizing means, the display apparatus 100 may further include a polarizing panel (not shown). The polarization panel is provided on the surface of the screen of the display apparatus 100 and polarizes the image output by the display apparatus 100 in a predetermined direction. If necessary, polarization may be performed using any one of linear polarization, left circular polarization, and right circular polarization.

However, in order to provide a multi-view for displaying a plurality of contents or to display 3D content including a left eye image and a right eye image according to various embodiments of the present disclosure, the display device may output a polarized image in a plurality of directions. It should be possible. In other words, polarization means having different polarization axes are required.

As an example, there may be a method of setting polarization differently by providing polarizing panels having different optical axes for respective regions of an image as shown in FIG. 18. This method is called a pattern retarder method, and in this case, the polarizing panel includes a pattern retarder.

The pattern retarder 132 is attached to the display panel 131 of the display apparatus 100. The pattern retarder 132 includes first patterns facing the odd-numbered lines in the pixel array of the display panel 131 and second patterns facing the even-numbered lines in the pixel array of the display panel 131. do. As described above, in this case, the optical axis of the first patterns and the optical axis of the second patterns are different from each other. For example, each of the first patterns and the second patterns may delay the phase of the incident light by 1/4 wavelength or -1/4 wavelength. In this case, the linearly polarized light is transformed into circularly polarized light having different directions. For example, the first patterns of the pattern retarder 132 convert light of an image displayed on the odd-numbered line of the pixel array into left circular polarized light, and the second patterns of the pattern retarder 132 are excellent display lines of the pixel array. It is possible to convert the light of the image displayed in the right polarized light.

In this case, the polarization filter of one spectacle device may have the same optical axis as the first patterns of the pattern retarder 132. In addition, the polarization filter of another spectacle device has the same optical axis as the second patterns of the pattern retarder 132. That is, the former spectacles block the light of the right polarized image while transmitting the light of the left polarized image, and the latter spectacles block the light of the left polarized image while transmitting the light of the right polarized image. . Thus, different viewers can watch differently polarized images. In the 3D stereoscopic image, the left eye polarization filter and the right eye polarization filter of one spectacle device have different optical axes, and the left eye image and the right eye image can be viewed.

On the other hand, such a pattern retarder 132 may be implemented in a manner that can be electrically controlled to change the polarization direction. In the above-described embodiment, when it is necessary to watch the right polarized image through the first eyeglass device or the left polarized image through the second eyeglass device, the pattern of the odd display line and the even display line of the display device is reversed. I can change it.

As an example, the pattern retarder 132 may be implemented as a liquid crystal cell. In the liquid crystal cell (not shown), the orientation is switched according to the driving voltage, and the polarization characteristic is changed according to the switched orientation. Here, the characteristic of polarization may be the phase or direction of polarization. That is, when a polarized image is incident, when a specific driving voltage is applied to the liquid crystal cell and the alignment is performed, the wavelength of the incident light may be delayed. For example, the pattern retarder 132 made of a liquid crystal cell may reverse the direction of circular polarization by changing the polarization direction of the linearly polarized image of the odd display line or by changing the phase of circular polarization of the even display line. . Although the liquid crystal cell is not technically limited, when the applied TN cell is implemented, when the applied voltage is 0, rotation of incident light is performed due to twisting of the liquid crystal molecules, and the polarization direction is converted to 90 degrees. That is, if the incident light is linearly polarized, the polarization direction is rotated by 90 degrees, and if left circularly polarized, the polarized light is transformed into right circularly polarized light, and the right circularly polarized light is transformed into left circularly polarized light.

In the above-described embodiment, the case in which the polarization axis of the pattern is different for each horizontal pixel line has been described, but it is not necessary to divide each pattern region of the pattern retarder for each horizontal line. That is, as shown in the embodiment illustrated in FIG. 18, the pattern retarder may include third patterns facing the odd-numbered lines and fourth patterns facing the even-numbered lines for each vertical line. In this case, the polarization filter of the spectacle device 200-11 may have the same optical axis (horizontal direction) as the first patterns of the pattern retarder. In addition, the polarization filter of the other spectacles 200-12 has the same optical axis (vertical direction) as the second patterns of the pattern retarder. Each eyeglass device views content 1 and content 2, respectively.

On the other hand, similar to the pattern conversion of the pattern retarder 132 described above, it is also possible to change the polarization properties of the entire polarizing panel. In particular, when the polarization type display apparatus provides the multi-view providing method by the alternate display of the image frame described earlier in the present specification, such a configuration is necessary because the polarization property is changed every time the image frame is changed. That is, as shown in FIG. 20, the polarization direction is changed by changing the polarization property of the polarization panel when the image frame is displayed.

When the horizontally polarized content view 2 is displayed in FIG. 20, viewing is possible through the glasses 200-3, but not through the glasses 200-4. When the content 1 is displayed, the display apparatus 100 vertically polarizes and outputs the displayed image, and a viewer wearing the spectacles 200-4 may watch the content view 1.

As described above, when the plurality of contents are output by being polarized differently for each frame, the contents may be provided to the viewer without reducing the resolution. However, since the display apparatus 100 must increase the frame rate, and the spectacle apparatus must have a shutter glass that can change the polarization axis corresponding to the display apparatus 100, an increase in manufacturing cost is caused. In the case of the pattern retarder method described above, there is no need to change the frame rate, and there is an advantage in that viewing is possible with an eyeglass device that is not provided with a shutter glass, but resolution may be degraded.

Composition of Glasses

Hereinafter, the configuration and operation of the polarizing glasses device.

FIG. 21 is a block diagram illustrating a configuration of a polarization glasses device according to various embodiments of the present disclosure. Referring to FIG.

Referring to FIG. 21, the polarizing glasses apparatus according to various embodiments of the present invention includes a front polarizer 251, a liquid crystal cell 252, a rear polarizer 253, an input unit 254, and a control unit 255.

As described above, the spectacle apparatus has a function of transmitting an image when the display device has the same optical axis as the polarized image and blocking the image when the display device is orthogonal. Accordingly, the user wearing the spectacle device can selectively watch the image.

One example of a polarizing glasses device is a spectacle device having a fixed polarization means. That is, the lens has a predetermined optical axis and transmits only the polarized image coinciding with the optical axis. Such spectacle apparatuses can be used both in the above-described pattern retarder type display device or multi-view type display device by alternating display of image frames. Since each eyeglass device does not need a separate synchronization operation with the display device, it is economical, and there is an advantage of less flicker occurring in the synchronization process.

However, when a user wants to view a polarized image corresponding to an optical axis different from the preset optical axis, the user must wear glasses with different optical axes or replace the polarizing lens. The user can simply replace the polarized lens mounted on the spectacle device and insert a new polarized lens to watch the polarized image. However, there is an inconvenience of manually changing the lens every time according to the polarization property of the image.

Therefore, in another embodiment, the spectacle device may include a means for changing the polarization property of the lens. Hereinafter, a spectacle device having such a means will be described.

In the above-described embodiment of FIG. 17, the spectacle device (not shown) may transmit an image that is polarized and output from the display apparatus 100, and for this purpose, the front polarizer 251, the liquid crystal cell 252, and the rear polarizer 253. ), And an input unit 254.

The front polarizer 251 has a polarization axis in the same direction as the image polarized by the display apparatus 100 and passes the image. As an example, the display apparatus 100 may output an image polarized in the horizontal direction. In this case, the polarizer 251 passes only the image polarized in the horizontal direction. On the other hand, when the spectacle device (not shown) includes a polarizer 251 capable of passing only the vertically polarized image, the spectacle device (not shown) does not transmit the horizontally polarized image. The front polarizer 251 blocks ambient light having different optical axes in addition to the image uniquely polarized by the display apparatus 100.

The liquid crystal cell 252 has a configuration in which the orientation is switched according to the driving voltage and the polarization characteristic is changed according to the switched orientation. The characteristic of polarization may be the phase or direction of polarization. That is, when a polarized image is incident, when a specific driving voltage is applied to the liquid crystal cell and the alignment is performed, the wavelength of the incident light may be delayed. For example, the liquid crystal cell may be an active retarder, change the polarization direction of the linearly polarized image according to a specific applied voltage (phase change), or change the phase of the circularly polarized light to change the polarization direction. Can be reversed. The characteristics of polarization will be appropriately changed to meet the purpose of opening the spectacle device (left eye or right eye) to transmit incident light or vice versa to close the spectacle device to prevent transmission of incident light. As an example, when no voltage is applied, the linearly polarized light may be rotated by 90 degrees (the phase difference is changed by λ / 2), and when the voltage is applied, the linear polarized light may be passed without changing the incident light.

Implementation of the liquid crystal cell is not limited to a specific technology, but in one embodiment may be a TN ECB (electrically controllable birefringence) cell or TN OCB (optically compensated bend) cell. When the liquid crystal cell is implemented as a twisted TN cell, when the applied voltage is 0, the incident light is rotated due to twisting of the liquid crystal molecules, and the polarization direction is converted by 90 degrees. That is, if the incident light is linearly polarized, the polarization direction is rotated by 90 degrees, and if left circularly polarized, the polarized light is transformed into right circularly polarized light, and the right circularly polarized light is transformed into left circularly polarized light.

The rear polarizer 253 polarizes the image passing through the liquid crystal cell again, and transmits only the polarization component perpendicular to the output polarization of the display device. Therefore, when the spectacles (not shown) are opened, it can be seen that the polarized image of the display apparatus 100 should be in a state capable of passing through the rear polarizer 253 through manipulation of the liquid crystal cell. On the contrary, when the shutter glasses are closed, the liquid crystal cell should transform the polarized output image of the display device to be perpendicular to the polarization axis of the rear polarizer 253.

Referring to the operation of the spectacle apparatus in the present embodiment, when the shutter is opened, the image output from the display apparatus and polarized in the vertical direction passes through the front polarizer 251 as it is, and the liquid crystal cell 252 is polarized while transmitting the image. The direction coincides with the polarization axis of the rear polarizer 253. Thus, the image passes through the spectacle device to the human eye. On the other hand, when the shutter is closed, the image output from the display device and polarized in the vertical direction passes through the front polarizer 251 as it is, but since the liquid crystal cell 252 also transmits the image as it is, the polarization direction is perpendicular to the rear polarizer 253. As a result, the polarized image does not pass through the spectacle apparatus and is not transmitted to the human eye.

The input unit 254 is a configuration in which a user may input a control command to control the liquid crystal cell 252 of the spectacle device. That is, the user may manipulate the input unit 254 to change the polarization direction of the polarized lens electrically. The input unit 254 may include a button, a touch pad, a toggle button, and the like for changing the polarization direction of the polarizing lens. For example, in FIG. 19, when a user who is watching content 2 through the spectacle device 200-11 presses a toggle button to change the polarization direction of the polarized lens, the spectacle device 200-11 is polarized light of the polarized lens. The direction is changed to the vertical direction, so that the user can watch the content 1.

The controller 255 controls the overall operations of the spectacles 200-11 and 200-12. In particular, the liquid crystal cell 252 is controlled to operate as described above according to the input of the input unit 254.

Here, the spectacles 200-11 and 200-12 may change the polarization directions of the left and right eye lenses, respectively. When the polarization directions of the left and right eye lenses are different from each other by changing only the polarization directions of one of the left and right eye lenses of the eyeglasses 200-11 and 200-12, the glasses may be used as the eyeglasses device for viewing 3D content.

In the polarization type 3D display device, since a plurality of viewers watch the same content, there is no need to perform communication between the display apparatus 100 and the spectacles 200, but as shown in FIGS. 19 and 20, In the case of viewing different contents, it is necessary to communicate with the display apparatus 100. For example, the eyeglasses 200-11 and 200-12 may receive audio data corresponding to each content from the interface unit 160 of the display apparatus 100 and output the audio data through an audio output unit (not shown). The control command input through the input unit 254 may be transmitted to the display apparatus 100. To this end, the spectacles 200-11 and 200-12 may further include an interface unit (not shown) connected to the display apparatus 100 to perform communication. Since the interface unit included in the spectacle device has been described in detail with reference to FIG. 6, a detailed description thereof will be omitted.

On the other hand, when viewing the content wearing the glasses device, there may be a mode for providing a plurality of content and a mode for providing 3D content. When the spectacle apparatuses 200-11 and 200-12 can change the polarization direction for each of the left and right eye lenses, the display apparatus 100 prompts the user to change the polarization direction of one of the left and right eye lenses when the mode is changed. can do. A user wearing the spectacles may change the polarization direction by manipulating the input unit 254.

If the spectacle device cannot change the polarization direction for each of the left and right eye lenses, the user may be prompted to replace the spectacle device when the mode is changed.
