Detailed Description
In order to make the aforementioned objects, features and advantages of the present invention comprehensible, embodiments accompanied with figures are described in further detail below.
With the development of eye tracking technology, there exist some display technologies that focus the resources on the attention area of human eyes in order to save GPU resources, and a block display method as shown in fig. 1 is adopted, where fig. 1 is a high-resolution display panel divided into a plurality of blocks 10. Only one block 10 is displayed per frame of the high resolution panel, and the remaining blocks 10 are displayed in a low resolution or projection mode.
The vertical data lines are converged to form 4 data line ports, and the Tcon selects one data line port to output signals according to the watching direction of human eyes of each frame. The STV signal is also divided into 3 scanline ports in the Panel, and the Tcon selects one scanline port to output a signal according to the gazing direction of the human eye of each frame.
For example, if the resolution of the VR panel is 8K (7680 × 5760), this can substantially reach the "retina" AR level. However, to drive such VR panels completely, the resources consumed are too large. After being partitioned as shown in FIG. 1, each partition has a resolution of
The number of pixels which need to be driven is reduced by 12 times, and GPU resources are greatly saved.
Therefore, the display panel is divided into blocks (or lines), more resources are provided for the gaze direction of the eyeballs, the display quality of the non-gaze direction is reduced, and the optimization of the display resources is realized on the premise of not greatly improving the capacity of a GPU chip. However, this technique is often very complicated in panel design, and the actual process is not easy to implement, and when the human eyes watch the block boundary, the blurred image generated by the low-resolution display or the projection display is always seen, which inevitably affects the display quality and the user experience.
In order to solve the problem that the display image quality and the user experience are poor when the human eyes watch the block boundary, referring to fig. 4-8, an embodiment of the present application provides a display panel, which may include a control module, and a first display substrate panel1 and a second display substrate panel2 which are stacked, wherein the resolution of the first display substrate panel1 is higher than that of the second display substrate panel 2.
The control module is configured to determine a target display area active block on the display panel according to the fixation point of the user; the first display substrate panel1 is controlled to display a first screen in the active block of the target display area, and the second display substrate panel2 is controlled to display a second screen outside the active block of the target display area.
Referring to fig. 2 and 3, the display panel is divided into a plurality of block display areas 21, an overlap area 22 is provided between adjacent block display areas 21, and the target display area active block includes a target block display area determined by the control module in the plurality of block display areas 21 according to the user's gaze point, and an overlap area 22 surrounding the target block display area.
An overlap region 22 is provided between each of the block display regions 21 and the adjacent block display region 21, and when a human eye watches a boundary region between the block display regions 21, as long as it is determined which block display region 21 the gazing point is closer to, the block display region 21 closest to the gazing point is determined as a target block display region, and the target block display region and the overlap region 22 surrounding the target block display region are determined as a target display region active block.
The area of the overlap region 22 can be determined as 1/3 of the area of each tile display region 21, that is, when a certain target tile display region 21 is displayed, not only the target tile display region is displayed, but also the surrounding overlap region 22 is displayed, and the overlap tile driving method can improve the picture quality of the border of the tile display regions.
For example, if the resolution of the display panel is 8K (7680 × 5760), this can substantially reach the "retina" a level. However, to drive such VR panels completely, the resources consumed are too large.
According to the overlapped block dividing method provided by the embodiment, the resolution of each target display area active block is
The number of pixels it needs to drive is reduced by 6.75 times, still enabling a large amount of resources to be reduced and enabling improved display quality and user experience when the point of regard is at the tile boundary.

The first display substrate panel1 may be a high resolution overlapping segmented substrate and the second display substrate panel2 may be a low resolution overlapping segmented substrate. The first display substrate panel1 and the second display substrate panel2 may have the same overlapping tiling.

Through the overlapped block driving mode provided by the embodiment, the central visual area (active block of the target display area) is separated from the peripheral visual area (an area outside the active block of the target display area), the central visual area is used for concentrating the high-quality display of resources, and the peripheral visual area is used for displaying with low quality, so that the effective optimization of GPU resources is realized, the display effect of higher resolution and higher refreshing frequency can be realized in the central visual area, and the user experience is improved.
Referring to fig. 2, data lines in a tile display area 21 and an overlap area 22 surrounding the tile display area 21 are connected to the same data line port; the scanning lines in the block display area 21 and the overlap area 22 surrounding the block display area 21 are connected to the same STV signal line. That is, data lines in the same Block (the Block display area and the overlapping area surrounding the Block display area) are all connected to the same data line port, and scan lines in the same Block are all connected to the same STV signal line.
Specifically, the first display substrate panel1 and the second display substrate panel2 are both of an overlapped block design, that is, the data lines in the overlapped area 22 are simultaneously connected to the data line ports corresponding to the two adjacent block display areas 21, and the scanning lines in the overlapped area 22 are simultaneously connected to the STV signals corresponding to the two adjacent block display areas 21 corresponding to the GOAs.
