Wherein the opening frequency of the left and right lenses is equal to half the current refresh rate of the display screen. For example, the current refresh rate of the display screen may be 240HZ, and then the opening frequency of the left eye lens and the opening frequency of the right eye lens are 120HZ respectively, where the current refresh rate 240HZ of the display screen may be a refresh rate that the display screen can support, and the current refresh rate of the display screen may also be made to reach 240HZ by increasing the refresh rate, so that when a user views a 3D signal, a picture will be smoother, and even in a game application with high dynamic switching, tailing and jitter on the picture are not easy to be seen, and the phenomenon of picture blocking and delay can be effectively relieved.

In this embodiment, the television acquires the input target 3D signal, where the target 3D signal itself already includes a left-eye frame and a right-eye frame, so that the processor of the television may identify an i-th frame corresponding to the left eye and an i+1th frame corresponding to the right eye in the target 3D signal, where i is a natural number. That is, left-eye frames and right-eye frames in the target 3D signal are cyclically alternated, and 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, 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.
It can be understood that when the signal of the game application is displayed, the display screen is continuously in the high-speed switching state, and if the refresh rate of the display screen is insufficient, the phenomenon of blocking or delaying the displayed screen easily occurs, so 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 fig. 3 and fig. 4, fig. 3 is a driving flow when the display screen provided in the embodiment of the present application is in the normal mode, and fig. 4 is a driving flow when the display screen provided in the embodiment of the present application is in the first display mode. The television comprises a processor, a display screen and a driving circuit, wherein the processor sends a target 3D signal to the driving circuit, namely Tcon, and the driving circuit can control the display screen to display the corresponding target 3D signal after receiving data. The display screen comprises pixels which are arranged in an array, the driving circuit comprises a row driving circuit and a column driving circuit, and the row driving circuit and the column driving circuit are connected with the pixels.
In a conventional driving process, when the driving circuit drives the display of the display screen, the display screen is controlled to scan line by line to display each frame in the target 3D signal, specifically, the processor outputs the voltage and the data signal corresponding to the target 3D signal to the driving circuit, and when the driving circuit receives the data, the driving circuit outputs a control signal: CKH (row clock) and STH (line synchronization) are supplied to the column driving circuit, CKV (field clock) and STV (field synchronization) are supplied to the row driving circuit, the column driving circuit outputs R/G/B signal voltage to the display screen to charge the pixels after processing, and the row driving circuit outputs a row scanning switch control signal to control each row to be turned on sequentially, 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 in the target 3D signal, and illustratively, the target 3D signal is output to the display screen, and the display screen is controlled to open two rows of pixels in the 2N-1 row and the 2N row to display the N-th row image 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 one row image of the target 3D signal. Specifically, by changing the timing sequence of the row scanning switch control signal output by the row driving circuit, two rows are sequentially controlled to be turned on, 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 voltages of the two charged rows are the same. It should be noted that, when the display screen is controlled to scan two rows of pixels in sequence, two rows of pixels may be controlled to be scanned simultaneously, or two rows of pixels may be scanned in a time-sharing manner to display a row of images of the target 3D signal.
When the display screen is in the first display state, the current refresh rate of the display screen is the first refresh rate, and for convenience of understanding, the refresh rate for controlling the progressive scanning of the display screen is defined as the second refresh rate, so that the refresh rate of the display screen can be improved by scanning two rows of pixels in sequence, so that the first refresh rate is twice the second refresh rate. For example, the first refresh rate may be 240HZ and the corresponding second refresh rate 120HZ.
It should be noted that, in this embodiment, the game application is taken as an example as an illustration, and when other types of target 3D signals can be set and displayed as required, the display screen is set to be in the first display mode, and the other types of target 3D signals are for example: sporting events and high frame rate movies, etc.
In one embodiment, acquiring the target 3D signal may include: acquiring an input initial 3D signal, wherein the initial 3D signal has an initial refresh rate and an initial resolution; the initial refresh rate and the initial resolution of the initial 3D signal are adjusted to obtain the target 3D signal such 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 in the vertical direction of the initial resolution is greater than half the resolution in the vertical direction of the display screen, part of the data is discarded so that the resolution in the vertical direction of the display screen is twice the resolution in the vertical direction of the target 3D signal. Further, the resolution in the horizontal direction of the initial resolution is adjusted so that the resolution in the horizontal direction of the target 3D signal is the resolution in the horizontal direction of the display screen.
For convenience of understanding, taking the design architecture of the display screen as the refresh rate 120HZ and the resolution of 4kx 2k as an example, after the processor receives the initial 3D signal, the resolution of the initial 3D signal is adjusted to 4kx 1k and the refresh rate is 240HZ no matter what the resolution and the refresh rate of the initial 3D signal are, so as to obtain the target 3D signal. For example, if the resolution of the initial 3D signal is 2K by 1K and the refresh rate is 120HZ, the resolution 1K in the vertical direction is kept unchanged, the resolution in the horizontal direction of the initial resolution is adjusted so that the resolution in the horizontal direction of the target 3D signal is adjusted to 4K, and the refresh rate is adjusted from 120HZ to 240HZ. For another example, if the initial 3D signal is 4k×2k@120hz, odd or even line data needs to be discarded, so that the resolution of the target 3D signal in the vertical direction is adjusted from 2K to 1K, and the refresh rate is adjusted from 120HZ to 240HZ, and when the adjusted target 3D signal is displayed on the display screen, the adjusted target 3D signal is matched with the parameters of the display screen, so that a picture with high definition and high refresh rate can be displayed, and the best smooth and clear display effect can be achieved.
It can be understood that the resolution of the target 3D signal is adjusted to 4K by 1K, and the refresh rate is 240HZ, and in this embodiment, two rows of images of the target 3D signal are displayed by controlling the display screen to open, so that the pixels of 2K rows of the display screen can display the target 3D signal although each frame is an image of 1K row. And the data volume that can be handled by the display screen of the television is: (4 k x 2 k) x 120HZ, when the display screen needs to display the target 3D signal, the amount of data to be processed is: (4K 1K) 240HZ, so that the data amount to be processed is unchanged for a display screen of the television, and the display screen can increase the refresh rate from 120HZ to 240HZ, so that a target 3D signal of 240HZ can be normally displayed.
If the television acquires a 2D signal, the multi-frame image of the 2D signal may be processed into an image corresponding to the left eye of the i-th frame image, an image corresponding to the right eye of the i+1th frame image, and i is a natural number; that is, if the television acquires a signal that is not in the 3D format, the signal in the 2D format may be processed into a target 3D signal having a left-eye frame and a right-eye frame.
In 205, a synchronization signal is generated from the i-th frame and the i+1-th frame.
At 206, a synchronization signal is sent to the 3D glasses to control the 3D glasses to cyclically open the left and right lenses and synchronize the time at which the left lens is open with the time at which the i-th frame is displayed and the time at which the right lens is open with the time at which the i+1-th frame is displayed.
The television is provided with a 3D transmitter, the 3D glasses are provided with a 3D receiver, the 3D glasses are, for example, shutter type 3D glasses, the 3D transmitter of the television can transmit left and right eye synchronous signals according to the time sequence of the ith frame and the (i+1) th frame in the target 3D signal, after the 3D receiver of the 3D glasses receives the synchronous signals, the 3D receiver of the 3D glasses controls the 3D glasses to cyclically open the left eye lens and the right eye lens, the time for opening the left eye lens is synchronous with the time for displaying the ith frame, the time for opening the right eye lens is synchronous with the time for displaying the (i+1) th frame, so that after the user wears the 3D glasses, the left eye of the user can see the content of the left eye frame in the target 3D signal through the left eye lens, the right eye can see 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 of a person.
When the display screen is in the first display mode, the current refresh rate of the display screen is the first refresh rate, the first refresh rate may be 240HZ, and then the opening frequency of the left lens and the opening frequency of the right lens are equal to half of the current refresh rate of the display screen, that is, the opening frequency of the left lens and the opening frequency of the right lens may reach 120HZ. In the related art, the current television display screen cannot support the refresh rate of 240HZ in hardware, and can not realize smoother 3D experience, and by the method of the embodiment, the refresh rate of the display screen can be increased from 120HZ to 240HZ, so that when 3D signals such as game application and the like are displayed, the requirements on the smoothness of pictures can be met, and the phenomena of picture blocking and delay can be effectively relieved.
It should be noted that, in this embodiment, the first refresh rate may be less than or greater than 240HZ, which is not limited in the embodiment of the present application, as long as the first refresh rate can achieve smooth display of the picture.
Referring to fig. 5, fig. 5 is a schematic diagram of a processing flow of a television display 3D signal according to an embodiment of the application.
For example, when the television receives a 3D signal from a peripheral source, if the 3D signal is identified as a game application signal or a 3D signal with other high refresh rate requirements, the automatic control processor enters the first display mode, if the 3D signal is identified as a non-game application signal or a 3D signal with other non-high refresh rate requirements, the automatic control processor enters the second display mode, and of course, if the television receives a 2D signal, the automatic control processor also enters the 2D display mode. In another example, the user may autonomously control the processor to enter the first display mode, the second display mode, or the 2D display mode by way of a remote control or voice, or the like.
