Problems solved by technology

[0002] With the demand of the market, most of the intelligent products with facial display are emerging one after another. Embedded products often refresh too slowly and have a single expression
The low image refresh rate on the LED display will easily lead to unsmooth animation and visual residue, which greatly reduces the user experience.
[0003] In order to facilitate hardware circuit wiring, the LED lights corresponding to each driver chip may not be arranged sequentially on the LED display screen according to its register address value. Continuous drive, because it takes a long time, the display refresh time of the entire animation image is also relatively long

Abstract

The invention discloses a method for improving the image refresh rate of an LED display screen. The method comprises the steps of obtaining animation source data; analyzing to obtain initial state data of on-off of each group of LED lamps in the LED display screen when each frame of animation image in the animation source data is displayed on the LED display screen; enabling each group of LED lamps to correspond to one driving chip; according to a pre-stored register position table of each group of LED lamps, performing sequence transformation on the initial state data of each group of LED lamps to generate final state data arranged according to register address values; and according to the final state data of each group of LED lamps corresponding to each driving chip, enabling each driving chip to respectively drive and control each group of corresponding LED lamps to finish the display of each frame of animation image on the LED display screen, so that the refreshing of a plurality of frames of animation images of animation source data is realized. According to the invention, the display refreshing time of the animation image on the LED display screen is greatly reduced, and theanimation playing frequency is improved.

Description

technical field [0001] The invention relates to the technical field of LED display, in particular to a method and a device for improving the image refresh rate of an LED display screen. Background technique [0002] With the demand of the market, most of the intelligent products with facial display are emerging one after another. Embedded products often have a slow refresh rate and a single expression. The low image refresh rate on the LED display will easily lead to unsmooth animation playback and visual residue, which greatly reduces the user experience. [0003] In order to facilitate hardware circuit wiring, the LED lights corresponding to each driver chip may not be arranged sequentially on the LED display screen according to its register address value. Continuous driving, because it takes a long time, causes the display refresh time of the entire animation image to be relatively long. [0004] Therefore, how to improve the image refresh rate of the LED display scree...
