Abstract

The present application provides a display data correction method, a display driving method and a display device. The display data correction method includes: receiving display data corresponding to pixel units of an irregularly-shaped display screen; determining whether the pixel units are in an area to be corrected; and if the pixel units are in the area to be corrected, correcting the display data corresponding to the pixel units to generate corrected display data.

First claim

What is claimed is:

1. A display data correction method, comprising:
receiving display data corresponding to a plurality of pixel units of an irregularly-shaped display screen;
determining whether the pixel units are in an area to be corrected; and
if the pixel units are in the area to be corrected, correcting the display data corresponding to the pixel units to generate corrected display data, wherein correcting the display data further comprises setting the display data corresponding to the pixel units in the area to be corrected to at least one gray scale value, wherein correcting the display data corresponding to the pixel units comprises:
setting the display data corresponding to the pixel units in the area to be corrected to a plurality of gray scale values of the at least one gray scale value, wherein the display data of each gray scale value respectively corresponds to at least one pixel unit in the area to be corrected; and
wherein the gray scale values of the display data corresponding to the pixel units in the area to be corrected are set to gradually change in a predefined direction of the area to be corrected.

2. The correction method according to claim 1 , wherein a maximum value of the plurality of gray scale values is 127 or 128, and a minimum value of the plurality of gray scale values is 0.

3. The correction method according to claim 1 , wherein the step of determining whether the pixel units are in the area to be corrected comprises:
extracting configured addresses of the pixel units corresponding to the display data;
confirming an address set of pixel units in the area to be corrected;
determining whether each of the configured addresses belongs to the address set; and
if the configured address belongs to the address set, determining the pixel unit corresponding to the configured address to be in the area to be corrected.

4. A display driving method, comprising:
receiving display data corresponding to pixel units of an irregularly-shaped display screen;
outputting the display data to the respective pixel units of the irregularly-shaped display screen;
determining whether the pixel units are in an area to be corrected;
if the pixel units are in the area to be corrected, correcting the display data corresponding to the pixel units to generate corrected display data, wherein correcting the display data further comprises setting the display data corresponding to the pixel units in the area to be corrected to at least one gray scale value, wherein correcting the display data corresponding to the pixel units comprises:
setting the display data corresponding to the pixel units in the area to be corrected to a plurality of gray scale values of the at least one gray scale value, wherein the display data of each gray scale value respectively corresponds to at least one pixel unit in the area to be corrected; and
wherein the gray scale values of the display data corresponding to the pixel units in the area to be corrected are set to gradually change in a predefined direction of the area to be corrected; and

driving the pixel units in the area to be corrected to display the corrected display data.

5. A display device, comprising:
a memory and a processor, wherein the memory and the processor are communicatively connected to each other, and the memory stores computer instructions, which are executable by the processor to perform the display driving method of claim 4 .

6. The display device of claim 5 , wherein a maximum value of the plurality of gray scale values is 127 or 128, and a minimum value of the plurality of gray scale values is 0.
