The following description is based on the exemplified embodiment of the present application, which should not be regarded as limiting other embodiments of the present application which are not described in detail.

[0037] Please refer to Figure 1 , Figure 1 The first flow diagram of the video display method provided by the embodiment of the present application is shown.

[0038] In 101, a target 3D signal is acquired, the target 3D signal comprising a left eye frame and a right eye frame;

[0040] The video display method in the embodiment can be applied in a television, the television can support 3D display, and people can wear 3D glasses at home to enjoy the visual experience brought by 3D display.

[0041] The television obtains the target 3D signal input in the embodiment, the target 3D signal includes left eye frame and right eye frame, and the 3D glasses are controlled to cyclically open the left eye lens and the right eye lens; when the left eye frame in the target 3D signal is displayed on the display screen, the 3D glasses are controlled to open the left eye lens; and when the right eye frame in the target 3D signal is displayed on the display screen, the 3D glasses are controlled to open the right eye lens.Exemplarily, the television has a 3D transmitter, and the 3D glasses have a 3D receiver; the 3D transmitter can transmit left and right eye synchronization signals; the 3D glasses can be shutter type 3D glasses, for example; the 3D receiver of the 3D glasses receives the synchronization signals, and the 3D glasses are controlled to orderly open the left and right eye lenses; after the user wears the 3D glasses, the left eye sees the content of the left eye frame in the target 3D signal through the left eye lens, and the right eye sees the content of the right eye frame in the target 3D signal through the right eye lens; and finally, the 3D display effect is synthesized in the brain.The opening frequency of the left eye lens and the opening frequency of the right eye lens are equal to half of the current refresh rate of the display screen.For example, if the current refresh rate of the display screen is 240HZ, then the opening frequency of the left eye lens and the opening frequency of the right eye lens are 120HZ respectively; wherein, the current refresh rate of the display screen 240HZ can be the refresh rate that the display screen itself can support, or the current refresh rate of the display screen can be 240HZ by means of increasing the refresh rate, so that the picture is smoother when the user watches the 3D signal, and even if the game application is high dynamic switching, the user is not easy to see the trailing and jitter on the picture, and the phenomenon of picture lag and delay can be effectively alleviated.

[0042] In the embodiment, the 3D signal is watched through the television, compared with using the VR hardware device, on the one hand, the television has higher refresh rate, supports larger size display, and has larger visual angle, so that the user can have better 3D visual experience; on the other hand, the user does not need to spend high cost to buy the VR hardware device, and the user can better experience the 3D display effect through the television by wearing the 3D glasses.

[0043] Please refer to Figure 2 , Figure 2 The second flowchart of the display method of the video provided in the embodiment of the application.

[0044] In 201, the target 3D signal is obtained, the i-th frame corresponding to the left eye and the i+1-th frame corresponding to the right eye in the target 3D signal are identified, and i is a natural number;

[0045] In 202, the target 3D signal is output to the display screen;

[0046] In 203, if the target 3D signal is the signal of the game application, it is determined that the display screen is in the first display mode;

[0047] In 204, a first display mode of the display screen is set, when the display screen is in the first display mode, the display screen scans two rows of pixels in turn to display each frame in the target 3D signal, and a current refresh rate of the display screen is a first refresh rate.

[0048] The display method of the video in the embodiment can be applied to a television, the television can support 3D display, and people can wear 3D glasses at home to enjoy the stereoscopic visual experience brought by 3D display.

[0049] In the embodiment, the television acquires the input target 3D signal, and the target 3D signal itself already includes left-eye frames and right-eye frames, so that the processor of the television can identify the i-th frame corresponding to the left eye and the i+1-th frame corresponding to the right eye in the target 3D signal, where i is a natural number. That is, the left-eye frames and the right-eye frames in the target 3D signal are cyclically and alternately arranged, if the target 3D signal is 240HZ, the first frame is a left-eye frame, the second frame is a right-eye frame, the third frame is a left-eye frame, and the fourth frame is a right-eye frame, and so on, so that the frame number corresponding to the left eye is 120HZ, and the frame number corresponding to the right eye is 120HZ.

[0050] It can be understood that when the signal of the game application is displayed, the display screen of the display screen is continuously in a high-speed switching state, if the refresh rate of the display screen is not enough, the displayed picture is prone to the phenomenon of lag or delay, so in the embodiment, if the target 3D signal is the signal of the game application, it is determined that the display screen is in the first display mode.

[0051] For example, please refer to Figure 3 and Figure 4 , Figure 3 the driving process of the display screen in the normal mode provided by the embodiment of the application, Figure 4 the driving process of the display screen in the first display mode provided by the embodiment of the application. The television includes a processor, a display screen and a driving circuit, the processor sends the target 3D signal to the driving circuit, that is, Tcon, and the driving circuit controls the display screen to display the corresponding target 3D signal after receiving the data. The display screen includes pixels arranged in an array, and the driving circuit includes row driving circuit and column driving circuit, and the row driving circuit and the column driving circuit are connected with the pixels.

[0052] In a conventional driving process, when the driving circuit drives the display screen to display, the display screen is controlled to scan each row to display each frame in the target 3D signal. Specifically, the processor outputs the voltage and data signal corresponding to the target 3D signal to the driving circuit. When the driving circuit receives the data, it outputs the control signal CKH (row clock) and STH (row synchronization) to the column driving circuit, and outputs the control signal CKV (field clock) and STV (field synchronization) to the row driving circuit. After processing, the column driving circuit outputs the R / G / B signal voltage to the display screen to charge the pixels. The row driving circuit outputs the row scanning switch control signal to control each row to be opened in turn, and only one row is opened each time, that is, only two rows of pixels are charged each time.

[0053] In this embodiment, if the first display mode of the display screen is set, after the target 3D signal is output to the display screen, the display screen is controlled to scan two rows of pixels in turn to display each frame in the target 3D signal. For example, the target 3D signal is output to the display screen, and the display screen is controlled to open the 2N-1th row and the 2Nth row of pixels to display the Nth row of images of the target 3D signal, where N is a natural number, so that two rows of pixels of the display screen are used to display one row of images of the target 3D signal. Specifically, by changing the timing of the row scanning switch control signal output by the row driving circuit, two rows are controlled to be opened in turn, and only two rows are opened each time, that is, only two rows of pixels are charged each time, and the data voltages of the two rows of pixels are the same. It should be noted that when the display screen is controlled to scan two rows of pixels in turn, the two rows of pixels can be scanned simultaneously or in time division to display one row of images of the target 3D signal.

[0054] When the display screen is in the first display state, the current refresh rate of the display screen is the first refresh rate. For ease of understanding, the refresh rate of the display screen controlled to scan each row is defined as the second refresh rate. Therefore, by scanning two rows of pixels in turn, the refresh rate of the display screen can be improved, so that the first refresh rate is twice the second refresh rate. For example, the first refresh rate can be 240HZ, and the corresponding second refresh rate is 120HZ.

[0055] It should be noted that the game application in this embodiment is an example for illustration. According to needs, other types of target 3D signals can also be set to set the display screen to the first display mode, such as sports events and high-frame-rate movies.

[0056] In an embodiment, the obtaining the target 3D signal can include: obtaining an input initial 3D signal, the initial 3D signal having an initial refresh rate and an initial resolution; adjusting the initial refresh rate and the initial resolution of the initial 3D signal to obtain the target 3D signal, so that the refresh rate of the target 3D signal is twice the second refresh rate, and the resolution of the display screen in the vertical direction is twice the resolution of the target 3D signal in the vertical direction. If the resolution of the initial resolution in the vertical direction is greater than half of the resolution of the display screen in the vertical direction, part of the data is discarded, so that the resolution of the display screen in the vertical direction is twice the resolution of the target 3D signal in the vertical direction. Further, the resolution of the initial resolution in the horizontal direction is adjusted, so that the resolution of the target 3D signal in the horizontal direction is the resolution of the display screen in the horizontal direction.

[0057] For the convenience of understanding, the design architecture of the display screen is taken as an example for illustration, the refresh rate is 120HZ, and the resolution is 4K*2K. After the processor receives the initial 3D signal, no matter what the resolution and refresh rate of the initial 3D signal are, the resolution of the initial 3D signal is adjusted to 4K*1K, and the refresh rate is 240HZ, so as to obtain the target 3D signal. For example, if the resolution of the initial 3D signal is 2K*1K, and the refresh rate is 120HZ, the resolution in the vertical direction is kept unchanged, the resolution of the initial resolution in the horizontal direction is adjusted, so that the resolution of the target 3D signal in the horizontal direction is adjusted to 4K, and at the same time, the refresh rate is adjusted from 120HZ to 240HZ. For another example, if the initial 3D signal is 4K*2K@120HZ, the odd or even row data needs to be discarded, so that the resolution in the vertical direction of the target 3D signal is adjusted from 2K to 1K, and at the same time, the refresh rate is adjusted from 120HZ to 240HZ. The target 3D signal obtained after adjustment can match the screen parameters when displayed on the display screen, and can display high-definition and high-refresh-rate pictures, so as to achieve the best smooth and clear display effect.

[0058] It can be understood that the resolution of the target 3D signal is adjusted to 4K*1K, and the refresh rate is 240HZ. In this embodiment, by controlling the display screen to display one row of images of the target 3D signal in two rows, the target 3D signal can be displayed on the display screen with 2K rows of pixels, although each frame is 1K rows of images. Moreover, the amount of data that can be processed by the display screen of the television is (4K*2K)*120HZ, and the amount of data that needs to be processed when the display screen needs to display the target 3D signal is (4K*1K)*240HZ. Therefore, for the display screen of the television, the amount of data that needs to be processed is unchanged, so that the refresh rate of the display screen can be increased from 120HZ to 240HZ, so that the target 3D signal with 240HZ can be normally displayed.

[0059] It should be noted that if the television acquires a 2D signal, the multiple frames of the 2D signal can also be processed into an image corresponding to the left eye of the ith frame and an image corresponding to the right eye of the ith+1 frame, i being a natural number; that is, if the television does not acquire a 3D signal, the 2D signal can also be processed into a target 3D signal having a left eye frame and a right eye frame.

[0060] In 205, a synchronization signal is generated according to the ith frame and the ith+1 frame.

[0061] In 206, the synchronization signal is sent to the 3D glasses to control the 3D glasses to cyclically open the left eye lens and the right eye lens, and to synchronize the time when the left eye lens is opened with the time when the ith frame is displayed, and to synchronize the time when the right eye lens is opened with the time when the ith+1 frame is displayed.

[0062] For example, the television has a 3D transmitter, and the 3D glasses have a 3D receiver, and the 3D glasses are, for example, shutter-type 3D glasses. The 3D transmitter of the television can transmit a left-right eye synchronization signal according to the timing of the ith frame and the ith+1 frame in the target 3D signal. After the 3D receiver of the 3D glasses receives the synchronization signal, the 3D glasses are controlled to cyclically open the left eye lens and the right eye lens, and to synchronize the time when the left eye lens is opened with the time when the ith frame is displayed, and to synchronize the time when the right eye lens is opened with the time when the ith+1 frame is displayed. Thus, after the user wears the 3D glasses, the left eye of the user sees the content of the left eye frame in the target 3D signal through the left eye lens, and the right eye sees the content of the right eye frame in the target 3D signal through the right eye lens, and finally the 3D display effect is synthesized in the brain. The left eye sees the image signal corresponding to the left eye, and the right eye sees the image signal corresponding to the right eye, so that a stereoscopic image is formed in the brain.

[0063] When the display screen is in the first display mode, the current refresh rate of the display screen is the first refresh rate, and the first refresh rate can be 240 HZ. Thus, the opening frequency of the left eye lens and the opening frequency of the right eye lens are equal to half of the current refresh rate of the display screen, that is, the opening frequency of the left eye lens and the opening frequency of the right eye lens can reach 120 HZ. In the related art, the current display screen of the television cannot support a refresh rate of 240 HZ in hardware, and cannot achieve a more smooth 3D experience. Through the method of the embodiment, the refresh rate of the display screen can be increased from 120 HZ to 240 HZ, so that when a 3D signal such as a game application is displayed, the requirement for the smoothness of the picture can be met, and the phenomenon of picture lag and delay can be effectively alleviated.

[0064] It should be noted that the first refresh rate in the embodiment can be less than or greater than 240 HZ, and the embodiment of the application does not limit this, as long as the first refresh rate can achieve smooth display of the picture.

[0065] Please refer toFigure 5 , Figure 5 The processing flow diagram of the television for displaying 3D signals is provided in the embodiment.

[0066] For example, when the television receives the 3D signal of the peripheral source, if it is identified that the 3D signal is a game application signal or other 3D signal with high refresh rate requirement, the automatic control processor enters the first display mode; if it is identified that the 3D signal is a non-game application signal or other 3D signal without high refresh rate requirement, the automatic control processor enters the second display mode; of course, if the television receives the 2D signal, the automatic control processor can also enter the 2D display mode. In another example, the user can independently control the processor to enter the first display mode, the second display mode or the 2D display mode through the remote controller or voice.

[0067] If the display screen is set in the first display mode, the processor processes the obtained initial 3D signal into a target 3D signal. Taking the design architecture of the display screen as an example, the refresh rate is 120HZ and the resolution is 4K*2K, after the processor receives the initial 3D signal, no matter what the resolution and refresh rate of the initial 3D signal are, the resolution of the initial 3D signal is adjusted to 4K*1K and the refresh rate is 240HZ, so as to obtain the target 3D signal matched with the parameters of the display screen. The processor sends the 4k*1k@240hz format VB1 data signal to the driving circuit, synchronously sends the IIC instruction to the driving circuit to inform the driving circuit to output the 4k*1k@240hz format data, the driving circuit provides the corresponding GOA time sequence control, the display screen scans two rows of pixels in turn to display each frame of the target 3D signal, and the processor also controls the 3D transmitter of the television to send the instruction to inform the 3D transmitter to send the synchronization signal. The 3D glasses as the receiving end cyclically and orderly open the left lens and the right lens according to the synchronization signal sent by the 3D transmitter, so that the left eye can see the 4k*1k@120hz video content and the right eye can see the 4k*1k@120hz video content. Therefore, when the target 3D signal is displayed, the resolution of the picture is high, the refresh rate is high, the display picture is smooth and clear, the phenomenon of picture lag and delay can be effectively alleviated, the visual angle of the television is large, the super large visual angle of 178° can be achieved, the television can support more large sizes, such as 55 inches, 65 inches, 70 inches and the like, so that the user can experience better stereoscopic visual effect through the television.

[0068] Please refer to Figure 6 , Figure 6 The structure diagram of the video display device is provided in the embodiment and applied to the television. The video display device 400 can include an acquisition module 401 and a display module 402.
