Abstract

The present application relates to a sub-pixel positioning coordinate correction method, device, equipment and readable storage medium, and relates to the field of OLED panel technology, including fitting the initial positioning coordinates of the sub-pixel to obtain the fitting coordinates; according to the fitting coordinates and The initial positioning coordinates are calculated to obtain coordinate distortion values; the fitting coordinates are corrected based on the coordinate distortion values ​​to obtain corrected sub-pixel coordinates. This application obtains a smoother positioning result by fitting the initial positioning coordinates of inaccurate sub-pixels, then quantifies the degree of distortion of the initial positioning coordinates through the fitting coordinates, and finally smoothes the fitting coordinates according to the quantization results Correction to obtain accurate sub-pixel coordinates to improve the positioning accuracy of sub-pixels, thereby improving the accuracy of brightness extraction.

Description

Subpixel positioning coordinate correction method, device, device and readable storage medium technical field The application relates to the technical field of OLED panels, in particular to a method, device, and device for correcting sub-pixel positioning coordinates. equipment and readable storage media. Background technique Compared with LCD (Liquid Crystal Display, liquid crystal display) screen, OLED (Organic Light‑Emitting Diode (Organic Light Emitting Diode) due to its better functionality, Higher, wider color gamut and other characteristics, the market demand is strong, and the industry is developing rapidly, especially in the field of smart phones, OLED It is becoming the mainstream of smartphone display development. However, since each sub-pixel in an OLED is driven independently and emits light Therefore, affected by the production process, the luminous intensity of each sub-pixel is inconsistent when it receives the same driving signal, thereby causing ...
