Abstract
A method and a device for removing afterimage, and a display panel. The method includes the image displayed on the display panel is first monitored to determine a target area of the image, and the target area is an area where a color does not change in the image; the background color in the target area is determined; the pixel data in the target area is traversed to determine a block in an image displayed in the target area; and finally, the target pixel in the block based on the background color is determined, and the color of the target pixel is switched according to a preset time interval.
Claims17
A method for removing an afterimage, comprising:
- monitoring an image displayed on a display panel to determine a target area of the image, wherein the target area is an area where a color does not change in the image;
- determining a background color in the target area;
- traversing pixel data in the target area to determine a block in an image displayed in the target area;
- and
- determining a target pixel in the block based on the background color, and switching a color of the target pixel according to a preset time interval;
- wherein the step of determining the target pixel in the block based on the background color, and switching the color of the target pixel according to the preset time interval comprises:
- determining target colors in the block except for the background color, counting a number of types of the target colors, and determining target pixels having the target colors in the block;
- comparing the number of types with a preset number threshold to generate a comparison result;
- and
- switching colors of the target pixels according to the preset time interval according to the comparison result.
A device for removing an afterimage, comprising:
- a monitoring circuit, configured for monitoring an image displayed on a display panel to determine a target area of the image, wherein the target area is an area where a color does not change in the image;
- a first determination circuit, configured for determining a background color in the target area;
- a second determination circuit, configured for traversing pixel data in the target area to determine a block in an image displayed in the target area;
- and
- an afterimage removal circuit, configured for determining a target pixel in the block based on the background color, and switching a color of the target pixel according to a preset time interval;
- wherein afterimage removal circuit is specifically configured for determining target colors in the block except for the background color, counting a number of types of the target colors, and determining target pixels having the target colors in the block;
- comparing the number of types with a preset number threshold to generate a comparison result;
- and switching colors of the target pixels according to the preset time interval according to the comparison result.
A display panel, comprising a memory, a processor chip, and a computer program stored in the memory and capable of running on the processor chip, wherein the computer program is executed to implement steps:
- monitoring an image displayed on a display panel to determine a target area of the image, wherein the target area is an area where a color does not change in the image;
- determining a background color in the target area;
- traversing pixel data in the target area to determine a block in an image displayed in the target area;
- and
- determining a target pixel in the block based on the background color, and switching a color of the target pixel according to a preset time interval;
- wherein the step of determining the target pixel in the block based on the background color, and switching the color of the target pixel according to the preset time interval comprises:
- determining target colors in the block except for the background color, counting a number of types of the target colors, and determining target pixels having the target colors in the block;
- comparing the number of types with a preset number threshold to generate a comparison result;
- and
- switching colors of the target pixels according to the preset time interval according to the comparison result.
