Abstract

The invention discloses a bar LED display screen data transmission method. Firstly, two ends of a light bar of the bar LED display screen are provided with signal input ports, and the signal input ports at two ends of the light bar are correspondingly connected with two ports of a receiving card respectively; then, after the receiving card carries out decompression on video data sent by a sending card, the data are sent to the signal input ports at two ends of the light bar; the signal input ports at two ends of the light bar serially transmit the received video signals to the middle of the light bar sequentially; and finally, whether the signals are transmitted completely is detected, if the signals are transmitted completely, an already-completion mark is generated and returned to the receiving card, the receiving card judges whether to receive the already-completion mark, if yes, a next data frame is sent, or, the current data frame is sent again. The transmission time can be effectively saved, the speed is doubled, the transmitted data packet loss rate is reduced, data can be quickly transmitted, and a display lag phenomenon and a smear phenomenon can be avoided.

Description

technical field [0001] The invention relates to a data transmission method of a strip-shaped LED display screen, which is mainly used in LED display screen manufacturers and LED display screen control system manufacturers, and belongs to the technical field of electronic detection. Background technique [0002] LED display is widely used in advertising media, stage background, building decoration, traffic information, sports venues, etc. With the growing market demand for LED display screens, more and more manufacturers have emerged. Although the LED display screen has developed rapidly in recent years, as a new industry and the excessive pursuit of interests by various manufacturers, the LED display screen industry does not have a unified industry standard. [0003] The reason why LEDs are widely valued and developed rapidly is because LEDs have the following advantages: high brightness, low operating voltage, low power consumption, long life, impact resistance and stable ...
