Abstract

Embodiments of the present application disclose a method and device for extracting OLED pixels. First, the collected pixel distribution map is subjected to vertical projection processing to generate a pixel grid, and the pixel grid is separated into odd and even columns to obtain an odd-numbered column grid and Even-numbered column grids, and then perform horizontal projection processing on the odd-numbered column grids and even-numbered column grids respectively to obtain odd-numbered column horizontal grids and even-numbered column horizontal grids, and then fuse the odd-numbered column horizontal grids and the even-numbered column horizontal grids. Process, generate the pixel effective area, determine the pixel center of the pixel effective area, divide the pixel effective area according to the pixel center, and obtain the pixel distribution map; separate the odd and even columns of the pixel grid to make the spacing between rows of pixels In addition, the area division process of the effective area of ​​​​the pixel can ensure that the result of the area division process covers all the energy of the pixel, achieving accurate extraction of OLED picture elements.

Description

technical field [0001] The present application relates to the technical field of image processing, in particular to a method and device for extracting OLED pixels. Background technique [0002] Compared with traditional thin film transistor (Thin Film Transistor, TFT) screens and (Liquid Crystal Display) screens, Organic Light-Emitting Diode (OLED) screens have advantages such as self-illumination, wide viewing angles, and good flexibility, among which the most critical The most important thing is that OLED can control the brightness point by point, so theoretically there is no color spot detection, but color spot repair is required. The basic process of color spot repair is to first accurately measure the brightness of each pixel of OLED, and each picture pixel The pixel includes at least one pixel, and transmits the brightness measurement data to the chip control center, and then through the control circuit, adjusts point by point according to the brightness measurement da...
