Abstract

The invention belongs to the technical field of LED display application, and discloses an LED display screen, a display circuit and a display control chip thereof. Since the display control chip including a decoding module, a logic control module, N switch modules and a shift register is employed, the shift register generates N sampling signals according to shift clock signals and decoding sampling signals and outputs the N sampling signals to the logic control module. The decoding module decodes row-line switching signals according to the shift clock signals and outputs the shift clock signals and the decoded row-line switching signals to the logic control module, the logic control module outputs N row-line switching signals to N switch modules according to the shift clock signals, the decoded row-line switching signals and N sampling signals, so that N switch modules output row-scanning control signal to drive LED display arrays. The problem that a conventional dynamic LCD display screen has too many application chips, complex PCB wiring and poor application reliability is solved.

Description

technical field [0001] The invention belongs to the technical field of LED display applications, and in particular relates to an LED display screen, a display circuit and a display control chip thereof. Background technique [0002] Due to the advantages of low voltage, energy saving, and long service life, LEDs are widely used in various fields. According to the scanning method of the LED display, the LED display can be divided into dynamic screen and static screen. The static screen means that each scanning line is turned on at the same time, and each LED light is controlled by a different driver chip; the dynamic screen uses The visual stay of the human eye, it only displays a certain line at a certain time, and then displays the next line at the next time, until all the lines are displayed, and then displays the first line, and so on, cyclically displaying to achieve the display of the entire page The purpose of the screen, please refer to figure 1 ,Such as figure 1 A...
