Abstract

The present disclosure provides an edge processing method for a display panel and a display panel having a device for processing an edge. The method includes: determining an irregular edge of the display panel and determining all edge pixels the irregular edge passes through; dividing all the edge pixels into n sets of edge pixels, where n≥2; and inputting frame image information to the display panel, wherein at least one set of the n sets of edge pixels is configured to display a frame image in at least one display frame, and is configured not to display the frame image in at least another display frame.

First claim

What is claimed is:

1. An edge processing method for a display panel, comprising:
determining an irregular edge of the display panel and determining all edge pixels the irregular edge passes through;
dividing all the edge pixels into n sets of edge pixels, where n≥2; and
inputting frame image information to the display panel, wherein at least one set of the n sets of edge pixels is configured to display a frame image in at least one display frame, and is configured not to display the frame image in at least another display frame, in such a manner that the frame image in the at least one display frame and the frame image in the at least another display frame have different edge positions.

2. The edge processing method according to claim 1 , wherein different sets of edge pixels are configured not to display the frame image in at least two display frames.

3. The edge processing method according to claim 2 , wherein the at least two display frames are successive display frames.

4. The edge processing method according to claim 2 , wherein n is 2, and the n sets of edge pixels comprise a first set of edge pixels and a second set of edge pixels;
the frame image is an odd-numbered frame image or an even-numbered frame image;
in the odd-numbered frame image, the first set of edge pixels is configured to display the frame image; and
in the even-numbered frame image, the first set of edge pixels is configured not to display the frame image.

5. The edge processing method according to claim 4 , wherein in the odd-numbered frame image, the first set of edge pixels is configured to display the frame image, and the second set of edge pixels is configured not to display the frame image; and
in the even-numbered frame image, the first set of edge pixels is configured not to display the frame image, and the second set of edge pixels is configured to display the frame image.

6. The edge processing method according to claim 5 , wherein
an area of a part of edge pixels in the first set of edge pixels located at a side of the irregular edge close to a center of a display region is larger than or equal to 50% of a total area of the edge pixels in the first set of edge pixels; and
an area of a part of edge pixels in the second set of edge pixels located at the side of the irregular edge close to the center of the display region is smaller than 50% of a total area of the edge pixels in the second set of edge pixels.

7. The edge processing method according to claim 1 , wherein the frame image information comprises m sets of frame image information, and different sets of frame image information correspond to different sets of edge pixels configured not to display the frame image, and wherein m≤n.

8. The edge processing method according to claim 7 , wherein the m sets of frame image information are sequentially displayed.

9. The edge processing method according to claim 1 , wherein in one display frame, the at least one set of edge pixels configured not to display the frame image is configured not to perform display.

10. The edge processing method according to claim 1 , wherein in one display frame, the at least one set of edge pixels configured not to display the frame image is configured to display a black color or a gray color.

11. The edge processing method according to claim 1 , wherein in one display frame, a maximum display brightness of pixels in the at least one set of edge pixels configured to display the frame image is lower than a maximum display brightness of pixels other than the edge pixels in the display panel.

12. The edge processing method according to claim 1 , wherein n is 3, and the n sets of edge pixels comprise a third set of edge pixels, a fourth set of edge pixels, and a fifth set of edge pixels;
an area of a part of edge pixels in the third set of edge pixels located at a side of the irregular edge close to a center of a display region is larger than or equal to 67% of a total area of the edge pixels in the third set of edge pixels;
an area of a part of edge pixels in the fourth set of edge pixels located at the side of the irregular edge close to the center of the display region is larger than or equal to 33% of a total area of the edge pixels in the fourth set of edge pixels, and smaller than 67% of the total area of the edge pixels in the fourth set of edge pixels; and
an area of a part of edge pixels in the fifth set of edge pixels located at a side of the irregular edge close to a center of the display region is smaller than 33% of a total area of the edge pixels in the fifth set of edge pixels.

13. The edge processing method according to claim 12 , wherein the frame image is a (3k+1)th frame image, a (3k+2)th frame image, or a (3k+3)th frame image, where k is an integer greater than or equal to 0;
in the (3k+1)th frame image, the third set of edge pixels is configured to display the frame image, and both the fourth set of edge pixels and the fifth set of edge pixels are configured not to display the frame image;
in the (3k+2)th frame image, the fourth set of edge pixels is configured to display the frame image, and both the third set of edge pixels and the fifth set of edge pixels are configured not to display the frame image; and
in the (3k+3)th frame image, the fifth set of edge pixels is configured to display the frame image, and both the third set of edge pixels and the fourth set of edge pixels are configured not to display the frame image.

14. The edge processing method according to claim 12 , wherein the frame image is a (3k+1)th frame image, a (3k+2)th frame image, or a (3k+3)th frame image, where k is an integer greater than or equal to 0; and
in each frame image of the (3k+1)th frame image, the (3k+2)th frame image and the (3k+3)th frame image, any two sets of the third set of edge pixels, the fourth set of edge pixels and the fifth set of edge pixels are configured to display the frame image; and in two successive frame images of the (3k+1)th frame image, the (3k+2)th frame image and the (3k+3)th frame image, different sets of edge pixels are configured not to display the frame image.
