Abstract
The present disclosure provides a display compensation method and device, and a display panel. The display compensation method includes: determining a central pixel column, a first pixel column, a second pixel column, a third pixel column, and a fourth column, in a predetermined direction; determining a target pixel area according to grayscale values of pixel units contained in each pixel column; and adjusting the grayscale value of each pixel unit in the target pixel area to be equal to one actual grayscale value of a picture to be displayed.
Claims19
A display compensation method, which is applied to a display panel comprising a plurality of pixel units, wherein the display compensation method comprises:
- selecting a pixel region within the display panel, wherein the pixel region comprises a part of the plurality of pixel units;
- determining a central pixel unit located at a central position of the pixel region;
- determining a central pixel column including the central pixel unit, a first pixel column and a second pixel column located on opposite sides of the central pixel column, a third pixel column located on one side of the first pixel column away from the central pixel column, and a fourth pixel column located on one side of the second pixel column away from the central pixel column, in a predetermined direction that forms an angle of 135 degrees or 45 degrees with a row direction of the pixel units;
- when current grayscale values of pixel units in the central pixel column are equal to each other, and current grayscale values of pixel units in the first pixel column are equal to each other, and current grayscale values of pixel units in the second pixel column are equal to each other, and current grayscale values of pixel units in the third pixel column are equal to each other, and current grayscale values of pixel units in the fourth pixel column are equal to each other, and
- when the current grayscale value of anyone pixel unit in the first pixel column and the current grayscale value of anyone pixel unit in the fourth pixel column are not equal, and
- when the current grayscale value of anyone pixel unit in the second pixel column and the current grayscale value of anyone pixel unit in the third pixel column are not equal,
- determining, the central pixel column, the first pixel column, the second pixel column, the third pixel column, and the fourth pixel column, as the target pixel area;
- and
- adjusting the grayscale value of each pixel unit in the target pixel area so that the grayscale value of each pixel unit in the target pixel area is equal to one actual grayscale value of a picture to be displayed.
