TECHNICAL FIELD
The present disclosure relates to the technical field of display, in particular to a display panel, a display device, and a method for driving a display device.
BACKGROUND
With the continuous development of display technology, three-dimensional (3D) display technology has attracted more and more attention. Three-dimensional display technology can make the display screen become three-dimensional and realistic. The principle of the 3D display technology is to use the left and right eyes of a person to receive the left-eye image and the right-eye image with a parallax respectively. After the two images with the parallax are respectively received by the left and right eyes of the person, the brain superimposes and fuses the image information to construct a 3D visual display effect.
In order to realize the compatibility of ultra-multi-viewpoint 3D display and light field display, the traditional sub-pixels are made into a pixel island structure, and each pixel island includes a plurality of sub-pixels. When display information of the plurality of sub-pixels is different, light field 3D display can be realized. The plurality of sub-pixels is grouped, and when each group of sub-pixels is combined for display, super multi-viewpoint 3D display can be realized. However, in the related art, each group of sub-pixels combined for display can only be provided with the same display information, that is, it can only be realized that each group of sub-pixels in the pixel island is fixedly combined for display. When positions of human eyes change, the sub-pixels combined for display cannot be changed accordingly.

In the third data selection circuit 8, the first electrodes of the first selection switches T11, T12, T13 and T14 are coupled to D3, and the first electrodes of the second selection switches T21, T22, T23 and T24 are coupled to D2. And so on, no more details here.
It should be noted that, during specific implementation, the viewpoint needs to correspond to the red sub-pixel, the blue sub-pixel and the green sub-pixel. Next, taking a sub-pixel row of a pixel island including 16 sub-pixels as an example, the correspondence between sub-pixels and viewpoints will be illustrated.
When a pixel island corresponds to 16 number of viewpoints, sub-pixels in each sub-pixel group in the same row in the pixel island need to display different display information. In some display cases, for example, it can be as shown in FIG. 2, the i-th viewpoint Pi corresponds to Ri, Gi and Bi of the first pixel island 22, where i is a positive integer less than or equal to 16. Take the coupling between the first pixel island and the first four data selection circuits arranged from left to right in FIG. 1 as an example for illustration, during specific implementation, the first selection switches T11, T12, T13 and T14 in the data selection circuits can be controlled to be turned on in turn through the data selection control lines Mill, MU3, MU5 and MU7, and the data signals corresponding to the viewpoints Pi to P4i are sequentially provided through Di, and simultaneously, the second selection switches T21, T22, T23 and T24 in the data selection circuits can be controlled to be turned off through the data selection control lines MU2, MU4, MU6 and MU8.
When one pixel island corresponds to 4 number of viewpoints, that is, four sub-pixels of each row in the pixel island are combined for display. In some display cases, for example, as shown in FIG. 3, the i-th viewpoint Pi corresponds to R4i-3˜R4i, G4i-3˜G4i and B4i-3˜B4i of the first pixel island 22, where i is a positive integer less than or equal to 4. In specific implementation, the first selection switches T11, T12, T13 and T14 in the data selection circuits can be controlled to be turned on simultaneously through the data selection control lines MU1, MU3, MU5 and MU7, and the data signals corresponding to the viewpoint Pi can be sequentially provided through Di, and simultaneously, the second selection switches T21, T22, T23, T24 in the data selection circuits are controlled to be turned off through the data selection control lines MU2, MU4, MU6, MU8.
In some display situations, for example, when the user's eyes move, the sub-pixels corresponding to the viewpoints are shifted to the right in FIG. 3. When one sub-pixel is shifted, the correspondence between the sub-pixels and the viewpoint in the user's gaze region may be as shown in FIG. 4, the first viewpoint P1 corresponds to R2-R5, G2-G5 and B2-B5 of the first pixel island 22, and the second viewpoint P2 corresponds to R6-R9, G6-G9 and B6-B9 of the first pixel island 22, the third viewpoint P3 corresponds to R10-R13, G10-G13 and B10-B13 of the first pixel island 22, and the fourth viewpoint P4 corresponds to R14-R16, G14-G16 and B14-B16 of the first pixel island 22 and R1, G1, B1 of the second pixel island 23. In a specific implementation, the sub-pixels in a sub-pixel group may be input with data signals that are not completely the same by only using the first selection switches in the data selection circuit. For example, data signals d4 and d1 are sequentially input to DO, data signals d1 and d2 are sequentially input to D1, data signals d2 and d3 are sequentially input D2, data signals d3 and d4 are sequentially input to D3, and data signals d4 and d1 are sequentially input to D4. A first data selection control signal is provided to MU1, and then the first data selection control signal is provided to MU3, MU5 and MU7 simultaneously to control T11 in each data selection circuit to be turned on first, and then control T12, T13 and T14 to be turned on simultaneously. A second data selection control signal is provided simultaneously to MU2, MU4, MU6, and MU8 to control the four second selection switches T21, T22, T23 and T24 in each data selection circuit to be turned off. Alternatively, the first selection switches and the second selection switches in the data selection circuit can also be used to input data signals that are not exactly the same to the sub-pixels in one sub-pixel group. For example, the data signal d4 is input to DO, the data signal d1 is input to D1, the data signal d2 is input to D2, the data signal d3 is input to D3, and the data signal d4 is input to D4. A first data selection control signal is simultaneously provided to MU2, MU3, MU5 and MU7 to control T21, T12, T13 and T14 in each data selection circuit to be turned on simultaneously. A second data selection control signal is simultaneously provided to Mill, MU4, MU6 and MU8 to control T11, T22, T23 and T24 in each data selection circuit to be turned off.
In some display situations, for example, the user's eyes continue to move, causing the sub-pixels corresponding to the viewpoints to shift one sub-pixel again to the right of FIG. 4. The correspondence between the sub-pixels and the viewpoints in the user's gaze region may be as shown in FIG. 5, the first viewpoint P1 corresponds to R3-R6, G3-G6 and B3-B6 of the first pixel island 22, the second viewpoint P2 corresponds to R7-R10, G7-G10 and B7-B10 of the first pixel island 22, the third viewpoint P3 corresponds to R11-R14, G11-G14 and B11-B14 of the first pixel island 22, and the fourth viewpoint P4 corresponds to R15-R16, G15-G16 and B15-B16 of the first pixel island 22 and R1, R2, G1, G2, B1 and B2 of the second pixel island 23. In a specific implementation, it is possible to utilize only the first selection switches in the data selection circuit to enable sub-pixels in a sub-pixel group to be input with data signals that are not exactly the same. The data signals d4 and d1 are sequentially input to DO, the data signals d1 and d2 are sequentially input to D1, the data signals d2 and d3 are sequentially input to D2, the data signals d3 and d4 are sequentially to input to D3, and the data signals d4 and d1 are sequentially input to D4. The first data selection control signal is provided to MU1 and MU3 simultaneously, and then the first data selection control signal is provided to MU5 and MU7 simultaneously to control T11 and T12 in each data selection circuit to be turned on simultaneously first, and then control T13 and T14 to be turned on simultaneously. The second data selection control signal is simultaneously provided to MU2, MU4, MU6 and MU8 to control the four second selection switches T21, T22, T23 and T24 in each data selection circuit to be turned off. Alternatively, the first selection switches and the second selection switches in the data selection circuit can also be used to input data signals that are not exactly the same to the sub-pixels in one sub-pixel group. For example, the data signal d4 is input to DO, the data signal d1 is input to D1, the data signal d2 is input to D2, the data signal d3 is input to D3, and the data signal d4 is input to D4. The first data selection control signal is simultaneously provided to MU2, MU4, MU5 and MU7 to control T21, T22, T13 and T14 in each data selection circuit to be turned on simultaneously. The second data selection control signal is simultaneously provided to MU1, MU3, MU6 and MU8 to control T11, T12, T23 and T24 in each data selection circuit to be turned off.

The first data selection control signal is simultaneously provided to MU2, MU4, MU5 and MU7 to control T21, T22, T13 and T14 in each data selection circuit 8 to be turned on simultaneously. The second data selection control signal is simultaneously provided to MU1, MU3, MU6 and MU8 to control T11, T12, T23 and T24 in each data selection circuit 8 to be turned off. In this way, the combined display scheme corresponding to FIG. 5 can be realized.
The method for driving the display device according to embodiments of the present disclosure can not only make the display information of the sub-pixels transition smoothly with the movement of the human eyes when the positions of the human eyes change, but also improve the display effect and user experience. As shown in FIG. 12 and FIG. 13, a plurality of groups of multiplexers in the data selection circuits are used to provide different data signals to a sub-pixel group through the multiplexers, and there is no need to increase the refresh frequency of the display device in the second display mode. In the case of insufficient system resources of the display device, the power consumption of the display device can be saved.
It should be noted that, in FIG. 8 to FIG. 13, the first data selection control signal for controlling the selection switch to be turned on is a high-level signal, and the second data selection control signal for controlling the selection switch to be turned off is a low-level signal.
To sum up, in the display panel, the display device and the driving method thereof according to embodiments of the present disclosure, the signal of the data input line is provided to the data lines by using the data selection circuit, so that the number of data input lines can be smaller than the number of data lines, thus, the amount of data input can be reduced. In addition, each data selection circuit in the display panel according to embodiments of the present disclosure includes at least two multiplexers, and different multiplexers in each data selection circuit are coupled to different data input lines. In this way, for one data selection circuit, under the control of the signals of a plurality of data selection control lines, signals of the same data input line can be respectively provided to each of the coupled data lines, and the signals of different data input lines can also be provided to corresponding data lines through different multiplexers respectively. That is, a plurality of data lines connected to the same data selection circuit may be input with the same data signal, or may be input with the data signals that are not completely the same. When a plurality of sub-pixels in the same row of each pixel island need to be combined for display, if the positions of the human eyes change, the sub-pixels combined for display are also changed, the display information of the sub-pixels combined for display may be changed accordingly by using the data selection circuits of the display panel according to embodiments of the present disclosure, and the display information of the sub-pixels may be smoothly transitioned with the movement of human eyes, thereby improving the display effect and user experience.
