Abstract
A compensation method of a display panel is provided and comprises: acquiring position information of a first sub-pixel; acquiring position information of a second sub-pixel located in the same pixel unit as the first sub-pixel when the position information of the first sub-pixel matches position information of an abnormal sub-pixel; acquiring position information of a third sub-pixel that is adjacent to the second sub-pixel and emits light of the same color; finally, setting a compensation parameter of the third sub-pixel as a compensation parameter of the second sub-pixel.

A compensation method of a display panel, comprising following steps:
- acquiring position information of a first sub-pixel in a target display panel, wherein the first sub-pixel is a sub-pixel to be compensated;
- acquiring position information of a second sub-pixel corresponding to the first sub-pixel when the position information of the first sub-pixel matches position information of an abnormal sub-pixel in a target display panel, wherein the second sub-pixel and the first sub-pixel are located in a same pixel unit;
- acquiring position information of a third sub-pixel corresponding to the second sub-pixel according to the position information of the second sub-pixel, wherein the third sub-pixel and the second sub-pixel are arranged adjacent to each other and emit light of a same color;
- setting a compensation parameter of the third sub-pixel as a compensation parameter of the second sub-pixel;
- wherein the step of acquiring the position information of the abnormal sub-pixel in the target display panel comprises:
- performing a lighting detection on the target display panel;
- determining the position information of the abnormal sub-pixel corresponding to an abnormal display of the target display panel;
- storing the position information of the abnormal sub-pixel in a compensation device.
A compensation method of a display panel, comprising following steps:
- acquiring position information of a first sub-pixel in a target display panel, wherein the first sub-pixel is a sub-pixel to be compensated;
- acquiring position information of a second sub-pixel corresponding to the first sub-pixel when the position information of the first sub-pixel matches position information of an abnormal sub-pixel in a target display panel, wherein the second sub-pixel and the first sub-pixel are located in a same pixel unit;
- acquiring position information of a third sub-pixel corresponding to the second sub-pixel according to the position information of the second sub-pixel, wherein the third sub-pixel and the second sub-pixel are arranged adjacent to each other and emit light of a same color;
- setting a compensation parameter of the third sub-pixel as a compensation parameter of the second sub-pixel.
A compensation device applied to a display panel, wherein the display panel comprises a plurality of pixel units, each of the pixel units comprises a plurality of sub-pixels with different light-emitting colors, wherein the compensation device comprises:
- a first acquiring module acquiring position information of a target position in a target display panel, wherein the position information comprises a target position information of an abnormal display on the display panel;
- a determining module determining whether position information of a first sub-pixel in the target display panel matches position information of an abnormal sub-pixel in the target display panel;
- a second acquiring module acquiring position information of a second sub-pixel corresponding to the first sub-pixel and position information of a third sub-pixel corresponding to the second sub-pixel when the position information of the first sub-pixel matches the position information of the abnormal sub-pixel in the target display panel;
- wherein the second sub-pixel and the first sub-pixel are located in a same pixel unit, and the third sub-pixel and the second sub-pixel are arranged adjacent to each other and emit light of a same color;
- and
- a processing module, setting a compensation parameter of the third sub-pixel as a compensation parameter of the second sub-pixel.
