Mura compensation display method, mura compensation display device, and computer readable storage medium

Abstract

The embodiment of the invention provides a mura compensation display method, a mura compensation display device, and a computer readable storage medium, which belong to the technical field of OLED display driving devices. The method comprises steps: gray scale data of each pixel point in a to-be-displayed image are acquired; matching between the gray scale data of each pixel point and pre-stored mura pixel compensation data is carried out to obtain the gray scale compensation data of each mura pixel point in the to-be-displayed image, wherein the mura pixel compensation data are preset gray scale compensation data of each preset mura pixel point in a mura area of a preset display picture of a terminal device; and according to the gray scale compensation data of each mura pixel point, the gray scale data of the mura pixel point are updated to display the to-be-displayed image. As the mura pixel compensation data are preset gray scale compensation data of each preset mura pixel point in the mura area of the preset display picture of the terminal device, the mura pixel compensation data do not need to occupy too much storage space, and compensation and correction on mura defects can be realized efficiently.

Description

technical field [0001] The present invention relates to the technical field of OLED display driving devices, in particular to a mura compensation display method and device, and a computer-readable storage medium. Background technique [0002] At present, my country's OLED industry has just emerged, and the manufacturing process of displays is still immature. AMOLED screens will inevitably show some visual defects. [0003] Among all visual defects, mura defects are the most complex and difficult to detect, because their contrast is very low, there is no clear edge, and it is also affected by the visual psychological factors of the observer. At present, using the traditional two characteristic parameters of contrast and area to distinguish can not get satisfactory mura defect detection effect. In addition, at present, it is also possible to capture a pure grayscale image displayed on a monitor and obtain a captured image. The gray scale data of each pixel in the captured im...

However, the algorithm calculation used in this method is too complicated and takes up the usage rate of the processor, thus affecting the performance of the processor.

However, if the compensation correction process is completed on the software in advance, it will need a large amount of flash or ram space temporarily to be able to store the grayscale data of each pixel in the captured image, which will also affect the performance of the flash or ram
