Embodiments of the present invention

Please refer to the drawings, where the same component symbols represent the same components. The principle of the present application is illustrated by implementing it in an appropriate computing environment. The following description is based on the illustrated specific embodiments of the present application, which should not be considered as limiting other specific embodiments of the present application that are not described in detail herein.

Please refer to FIG. 1 , which is a schematic diagram of a first flow chart of a method for displaying a video provided in an embodiment of the present application.

In 101, a target 3D signal is acquired, where the target 3D signal includes a left-eye frame and a right-eye frame;

In 102, the 3D glasses are controlled to cyclically turn on the left eye lens and the right eye lens. When the display screen displays the left eye frame in the target 3D signal, the 3D glasses are controlled to turn on the left eye lens. When the display screen displays the right eye frame in the target 3D signal, the 3D glasses are controlled to turn on the right eye lens. The turning-on frequency of the left eye lens and the turning-on frequency of the right eye lens are equal to half of the current refresh rate of the display screen.

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

In this embodiment, the television obtains the input target 3D signal, which includes a left eye frame and a right eye frame, and controls the 3D glasses to cyclically open the left eye lens and the right eye lens. When the display screen displays the left eye frame in the target 3D signal, the 3D glasses are controlled to open the left eye lens, and when the display screen displays the right eye frame in the target 3D signal, 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 signal and controls the 3D glasses 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 synthesizes the 3D display effect in the brain. Among them, 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, the current refresh rate of the display screen may be 240 Hz, then the opening frequency of the left eye lens and the opening frequency of the right eye lens are 120 Hz respectively. The current refresh rate of the display screen, 240 Hz, may be the refresh rate supported by the display screen itself, or the current refresh rate of the display screen may be increased to 240 Hz. Thus, when the user watches the 3D signal, the picture will be smoother, and even for high-dynamic switching game applications, it is not easy to see tailing or jitter on the picture, which can effectively alleviate the phenomenon of picture freeze and delay.

In this embodiment, when watching 3D signals through a TV, compared with using VR hardware devices, on the one hand, the TV has a higher refresh rate, supports larger display sizes, and has a larger viewing angle, thereby improving the user's 3D visual experience; on the other hand, there is no need to spend a high cost to purchase VR hardware devices, and the user only needs to wear 3D glasses to better experience the 3D stereoscopic display effect through the TV.

Please refer to FIG. 2 , which is a schematic diagram of a second flow chart of a method for displaying a video provided in an embodiment of the present application.

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

In 202, the target 3D signal is output to a display screen;

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

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 is controlled to sequentially scan two rows of pixels to display each frame of the target 3D signal. The current refresh rate of the display screen is the first refresh rate.

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

In this embodiment, the TV obtains the input target 3D signal, which already includes the left eye frame and the right eye frame. Therefore, the TV processor 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 frame and the right eye frame in the target 3D signal alternate cyclically. If the target 3D signal is 240HZ, then Then the first frame is the left eye frame, the second frame is the right eye frame, the third frame is the left eye frame, the fourth frame is the right eye frame, and so on, so that the number of frames corresponding to the left eye is 120HZ, and the number of frames corresponding to the right eye is 120HZ.

It can be understood that when displaying the signal of the game application, 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 freeze or delay. Therefore, in this 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.

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

In the conventional driving process, when the driving circuit drives the display of the display screen, the display screen is controlled to scan row by row to display each frame of 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 also outputs the control signals: CKH (row clock) and STH (row synchronization) to the column driving circuit, CKV (field clock) and STV (field synchronization) to the row driving circuit. After processing, the column driving circuit will output the R/G/B signal voltage to the display screen to charge the pixels. The row driving circuit will output the row scanning switch control signal to control each row to be turned on in turn, and only one row is turned on at a time, that is, only one row of pixels is charged at a time.

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 sequence to display each frame of the target 3D signal. For example, the target 3D signal is output to the display screen, and the display screen is controlled to open two rows of pixels, the 2N-1 row and the 2N row, to display the Nth row of the target 3D signal, where N is a natural number, so that the two rows of pixels of the display screen are used to display a row of the target 3D signal. Specifically, by changing the timing of the row scanning switch control signal output by the row driving circuit, the two rows are controlled to be turned on in sequence, and only two rows are turned on at a time, that is, only two rows of pixels are charged at a time, and the data voltage of the two rows is the same. It should be noted that when controlling the display screen to scan two rows of pixels in sequence, the two rows of pixels can be controlled to be scanned simultaneously, or the two rows of pixels can be scanned in time-sharing to display a row of the target 3D signal.

Among them, 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 controlling the display screen to scan line by line is defined as the second refresh rate. Then, by scanning two rows of pixels in sequence, the refresh rate of the display screen can be increased so that the first refresh rate is twice the second refresh rate. Exemplarily, the first refresh rate can be 240HZ, and the corresponding second refresh rate is 120HZ.

It should be noted that in this embodiment, the game application is used as an example for illustration. When other types of target 3D signals are displayed as needed, the display screen is set to the first display mode. Other types of target 3D signals include: sports events and high frame rate movies.

In one embodiment, obtaining a target 3D signal may 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 a 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, discarding part of the data 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, adjusting the resolution of the initial resolution in the horizontal direction so that the resolution of the target 3D signal in the horizontal direction is the resolution of the display screen in the horizontal direction.

For ease of understanding, let's take the design architecture of a display screen with a refresh rate of 120HZ and a resolution of 4K*2K as an example. After the processor receives the initial 3D signal, no matter what the resolution and refresh rate of the initial 3D signal are, it will adjust the resolution of the initial 3D signal to 4K*1K and the refresh rate to 240HZ 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 vertical resolution of 1K is kept unchanged, and the horizontal resolution of the initial resolution is adjusted so that the horizontal resolution of the target 3D signal 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, odd or even lines need to be discarded. Data is used to adjust the vertical resolution of the target 3D signal from 2K to 1K, and at the same time adjust the refresh rate from 120HZ to 240HZ. When the target 3D signal obtained after the adjustment is displayed on the display screen, it matches the display screen parameters and can display high-definition and high-refresh-rate images, achieving the best smooth and clear display effect.

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, the target 3D signal can be displayed on 2K rows of pixels on the display screen by controlling the display screen to open two rows to display a row of images of the target 3D signal, although each frame is 1K rows of images. Moreover, the amount of data that can be processed by the display screen of the TV is: (4K*2K)*120HZ. When the display screen needs to display the target 3D signal, the amount of data to be processed is: (4K*1K)*240HZ. Therefore, for the display screen of the TV, the amount of data to be processed remains unchanged, so that the display screen can increase the refresh rate from 120HZ to 240HZ, so that the target 3D signal of 240HZ can be displayed normally.

It should be noted that if the TV acquires a 2D signal, the multiple frames of the 2D signal can also be processed into an image in which the i-th frame corresponds to the left eye image, and the i+1-th frame corresponds to the right eye image, where i is a natural number; that is, if the TV does not acquire a 3D format signal, the 2D format signal can also be processed into a target 3D signal with a left eye frame and a right eye frame.

In 205, a synchronization signal is generated based on the i-th frame and the (i+1)-th frame.

In 206, a synchronization signal is sent to the 3D glasses to control the 3D glasses to cyclically open the left and right glasses, and synchronize the opening time of the left glass with the time of displaying the i-th frame, and synchronize the opening time of the right glass with the time of displaying the i+1-th frame.

Exemplarily, a television has a 3D transmitter, and 3D glasses have a 3D receiver. The 3D glasses are shutter-type 3D glasses, for example. The 3D transmitter of the television can transmit left-eye and right-eye synchronization signals according to the timing of the i-th frame and the i+1-th frame in the target 3D signal. After receiving the synchronization signal, the 3D receiver of the 3D glasses controls the 3D glasses to cyclically open the left eye lens and the right eye lens, and synchronize the opening time of the left eye lens with the time of displaying the i-th frame, and synchronize the opening time of the right eye lens with the time of displaying the i+1-th frame, so that after the user wears the 3D glasses, the user's 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 synthesizes the 3D display effect in the brain. The left eye sees the image signal corresponding to the left eye, and the right eye sees the signal corresponding to the right eye image, so that a stereoscopic image is formed in the human brain.

When the display screen is in the first display mode, the current refresh rate of the display screen is the first refresh rate, which can be 240HZ, then 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 120HZ. In the related art, the display screen of the current TV cannot support the refresh rate of 240HZ in hardware, and cannot achieve a smoother 3D experience. Through the method of this embodiment, the refresh rate of the display screen can be increased from 120HZ to 240HZ, so that when displaying 3D signals such as game applications, the requirements for picture smoothness can be met, and the phenomenon of picture freeze and delay can be effectively alleviated.

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

Please refer to FIG. 5 , which is a schematic diagram of a processing flow of displaying a 3D signal on a television according to an embodiment of the present application.

For example, when the TV receives a 3D signal from an external source, if the 3D signal is identified as a game application signal, or other 3D signals requiring a high refresh rate, the processor is automatically controlled to enter the first display mode. If the 3D signal is identified as a non-game application signal, or other 3D signals requiring a non-high refresh rate, the processor is automatically controlled to enter the second display mode. Of course, if the TV receives a 2D signal, the processor can also be automatically controlled to 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 a remote control or voice.

If the display screen is set in the first display mode, the processor will process the acquired initial 3D signal into a target 3D signal. Taking the design architecture of the display screen with a refresh rate of 120HZ and a resolution of 4K*2K as an example, 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 will be adjusted to 4K*1K and the refresh rate will be 240HZ to obtain a target 3D signal that matches the display screen parameters. The processor will send a 4k*1k@240hz format VB1 data signal to the drive circuit, and simultaneously send an IIC instruction to the drive circuit to inform the drive circuit The circuit needs to output 4k*1k@240hz format data, and the driving circuit will provide the corresponding GOA timing control display to scan two rows of pixels in sequence to display each frame in the target 3D signal. At the same time, the processor will control the 3D transmitter of the TV to send instructions, telling the 3D transmitter to send a synchronization signal. As the receiving end, the 3D glasses will cyclically open the left and right lenses in an orderly manner according to the synchronization signal emitted 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 displaying the target 3D signal, the picture resolution is high, the refresh rate is high, the display picture is smooth and clear, and the phenomenon of picture jamming and delay can be effectively alleviated. In addition, the TV has a large viewing angle, which can reach an ultra-large viewing angle of 178°. The TV can also support more large sizes, such as 55 inches, 65 inches, 70 inches and other larger sizes, so that users can experience better stereoscopic visual effects through the TV.

When the display screen displays the left eye frame in the target 3D signal, the 3D glasses are controlled to turn on the left eye lens. When the display screen displays the right eye frame in the target 3D signal, the 3D glasses are controlled to turn on the right eye lens. The turning-on frequency of the left eye lens and the turning-on frequency of the right eye lens are equal to half of the current refresh rate of the display screen.

In one embodiment, the display module 402 can be used to: output the target 3D signal to a display screen; set a first display mode of the display screen, and when the display screen is in the first display mode, control the display screen to scan two rows of pixels in sequence to display each frame in the target 3D signal, and the current refresh rate of the display screen is the first refresh rate.
