MULTI-POINT INTERLEAVED DYNAMIC SCANNING METHOD AND SYSTEM FOR LED DISPLAY SCREEN, AND STORAGE MEDIUM

The present application relates to a multi-point interleaved dynamic scanning method and system for an LED display screen, and a storage medium. The multi-point interleaved dynamic scanning method for an LED display screen comprises: dividing an LED display screen into N x N small cells of M pixel points; and performing dynamic scanning for two layers of nested loops. The step of executing dynamic scanning for two layers of nested loops specifically comprises: for a first-layer loop, performing scanning and lighting between small cells, wherein a scanning and lighting mode includes progressive and/or interlaced scanning; and for a second-layer loop, scanning and lighting other pixels in small cells. By means of the present application, the spatial brightness uniformity of an LED display screen within a single scanning-row time can be improved without reducing the number of scanning rows, without increasing the number of drive chips, or without increasing costs or the difficulty of PCB wiring.
