Abstract

A display optimization and display driving method and apparatus, display apparatus, and storage medium are disclosed. The display optimization method includes: selecting an irregular-shaped edge of a display panel, calculating an area ratio of an area of a display region of a pixel unit passed by the irregular-shaped edge and an area of the pixel unit; and determining a grayscale parameter of the pixel unit according to the area ratio.

What is claimed is:

1. A display optimization method, comprising:
selecting an irregular-shaped edge of a display panel, and calculating an area ratio of an area of a display region of a pixel unit passed by the irregular-shaped edge and an area of the pixel unit; and
determining a grayscale parameter of the pixel unit according to the area ratio,
wherein calculating the area ratio of the area of the display region of the pixel unit passed by the irregular-shaped edge to the area of the pixel unit comprises:
connecting two intersections between the irregular-shaped edge and the pixel unit by using a straight line, and dividing the pixel unit into the display region and a non-display region by using the straight line.

2. The display optimization method according to claim 1 , wherein the irregular-shaped edge comprises an arc-shaped corner edge or an edge, with a corner formed by straight-lines, of the display panel.

3. The display optimization method according to claim 2 , wherein determining the grayscale parameter of the pixel unit according to the area ratio comprises:
obtaining the grayscale parameter from the area ratio according to a predetermined gamma function relationship between a predetermined grayscale value and the area ratio.

4. The display optimization method according to claim 3 , wherein obtaining the grayscale parameter from the area ratio according to the predetermined gamma function relationship between the predetermined grayscale value and the area ratio comprises:
dividing a range of grayscale values into multiple intervals, each interval having a corresponding eigenvalue;
obtaining a first grayscale value from the area ratio according to the gamma function relationship, determining a first interval in which the first grayscale value falls, and selecting an eigenvalue of the first interval to modify the first grayscale value, and using a modified first grayscale value as the grayscale parameter.

5. The display optimization method according to claim 1 , wherein determining the grayscale parameter of the pixel unit according to the area ratio comprises:
obtaining the grayscale parameter from the area ratio according to a predetermined gamma function relationship between a predetermined grayscale value and the area ratio.

6. The display optimization method according to claim 5 , wherein obtaining the grayscale parameter from the area ratio according to the predetermined gamma function relationship between the predetermined grayscale value and the area ratio comprises:
dividing a range of grayscale values into multiple intervals, each interval having a corresponding eigenvalue;
obtaining a first grayscale value from the area ratio according to the gamma function relationship, determining a first interval in which the first grayscale value falls, and selecting an eigenvalue of the first interval to modify the first grayscale value, and using a modified first grayscale value as the grayscale parameter.

7. The display optimization method according to claim 6 , further comprising:
obtaining a modified area ratio from the modified first grayscale value according to the gamma function relationship,
wherein the modified area ratio is used to adjust the area of the display region of the pixel unit.

8. The display optimization method according to claim 1 , further comprising:
storing the grayscale parameter for accessing when the display panel performs a display operation.

9. A display optimization apparatus, comprising:
a processor; and
a memory on which computer-executable instructions are stored,
wherein the computer-executable instructions, when executed by the processor, cause the processor to perform the display optimization method according to claim 1 .

10. A non-transitory storage medium storing computer-executable instructions that, when executed by a computer, cause the computer to perform the display optimization method according to claim 1 .

11. A display optimization apparatus, comprising:
a calculation module configured to calculate an area ratio between an area of a display region of a pixel unit passed by an irregular-shaped edge and an area of the pixel unit; and
a determination module configured to determine a grayscale parameter of the pixel unit according to the area ratio,
wherein the calculation module is further configured to connect two intersections between the irregular-shaped edge and the pixel unit by using a straight line, and divide the pixel unit into the display region and a non-display region by using the straight line.

12. A display driving method, comprising:
determining a display grayscale value displayed by a pixel unit passed by an irregular-shaped edge according to a predetermined display grayscale signal and a previously stored grayscale parameter, so that the pixel unit displays according to the display grayscale value,
wherein the grayscale parameter is determined according to the display optimization method according to claim 1 .

13. The display driving method according to claim 12 , wherein the display grayscale value is obtained by calculating the predetermined display grayscale signal and the grayscale parameter.

14. A display driving apparatus, comprising:
a processor;
a memory on which computer-executable instructions are stored,
wherein the computer-executable instructions, when executed by the processor, cause the processor to perform the display driving method according to claim 12 .

15. A display apparatus comprising a display panel and the display driving apparatus according to claim 14 , wherein the display panel has an irregular-shaped edge, and the display driving apparatus is coupled to the display panel and is configured to drive the display panel.

16. A non-transitory storage medium storing computer-executable instructions that, when executed by a computer, cause the computer to perform the display driving method according to claim 12 .
