|Title:||METHOD AND DEVICE FOR ACQUIRING MURA COMPENSATION VALUE, AND DISPLAY PANEL|
A method and device for acquiring a mura compensation value, and a display panel. The method comprises: acquiring an image of a detection picture on a display panel, and extracting a display data matrix of three primary colours and a first correction matrix of three primary colours therefrom (steps A and B); acquiring position coordinates of an extreme point of the first correction matrix of three primary colours (step C); obtaining a second correction matrix of three primary colours and a third correction matrix set (steps D and E); and obtaining, according to the third correction matrices, a compensation matrix as a mura compensation value of the display panel (step F). The compensation mode is more intricate, and the compensation precision and accuracy are more high; moreover, compensation is performed only when a deviation exceeds a certain threshold value; when the compensation precision is improved, the data volume of generated compensation data is relatively small, and the calculation speed is fast, thereby reducing the algorithm complexity; moreover, gray-scale value compensation is performed on a display panel by using a compensation matrix, and the mura of the display panel can be eliminated, thereby improving the display effect of the display panel and improving the product yield rate.
