Abstract

The invention relates to an OLED display panel Mura compensation method and device and a readable medium; the method comprises the steps: obtaining a gray scale image and an n-point positioning image of a plurality of gray scale values from low to high of the OLED display panel, and the n is greater than or equal to 2; cutting an area where the display panel is located according to the n-point positioning image; calculating the GAMMA index value of the pixel in each gray scale picture according to the pixel value of the gray scale picture and the exposure time parameter during shooting; according to the GAMMA index values of the pixels, calculating the actual gray-scale values needed by the pixels to reach the target brightness in a power operation mode; and acquiring thr Mura compensation data through calculation according to the actual gray-scale value and the gray-scale value, and executing the Mura compensation. The method has the advantages that a good Mura phenomenon compensation effect can be obtained, and the display effect is optimized.

Description

technical field [0001] The invention relates to the field of display technology, in particular to a compensation method and device for OLED display panel Mura. Background technique [0002] OLED (Organic Light-Emitting Diode, Organic Light-Emitting Diode), as a current-mode light-emitting device, has been increasingly used in high-performance displays. Due to its self-luminous characteristics, it has many advantages compared with LCD, such as high contrast, ultra-thin, and bendable. However, brightness uniformity and afterimage are still the two main problems it faces at present. To solve these two problems, in addition to the improvement of the process, compensation technology is often used. Compensation methods can be divided into two categories: internal compensation and external compensation. Internal compensation refers to a method of using a sub-circuit constructed of a TFT (Thin Film Transistor, thin film transistor) inside a pixel to perform compensation. External...
