Abstract

The embodiment of the invention discloses an extraction method and device for OLED drawing, firstly, vertical projection processing is carried out on the collected pixel distribution map, and the pixel grid is generated, performing parity column separation processing on the pixel grids to obtain the odd column grid and the even column grid, performing transverse projection processing on the odd column grids and the even column grids respectively to obtain the odd column transverse grid and the even column transverse grid, fusing the odd column transverse grids and the even column transverse grids, generating the pixel effective area, and determining the pixel center of the pixel effective area, region division processing is carried out on the pixel effective area according to the pixel center, and obtaining the pixel map; by performing parity column separation processing on the pixel grid, the interval between row pixels is increased, region division processing is carried out on the pixel active region, so that all energy of the pixel can be covered by the result of the region division processing, and accurate extraction of the OLED image is realized.

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...
