Problems solved by technology

The display module is a dot matrix of LED lights to form a screen to emit light; the control system is to control the on and off conditions in the area to convert the content displayed on the screen; the power system is to convert the input voltage and current to meet the needs of the display screen; but In the existing display control of LED display screens, there is still a lack of fine control over the color and display content displayed on the LED display screen, and it is impossible to make the content displayed on the corresponding LED display screen under low-cost control. More delicate and fidelity

Abstract

The invention discloses a display control method and system for an LED display screen. The method comprises the following steps: receiving video signal data transmitted by an upper computer, and converting the video signal data into video stream data; obtaining a horizontal synchronizing signal and a field synchronizing signal of the video stream data, and coding the video stream data based on the horizontal synchronizing signal and the field synchronizing signal to obtain coded video stream data; a built-in scanning and playing control module decodes the encoded video stream data and caches the decoded video stream data in a corresponding cache region; the scanning and playing control module scans according to the sequence of the decoded video stream data cached to form a screen display control signal; and outputting the screen display control signal to the LED display screen, and controlling the LED display screen to display and play based on the screen display control signal. According to the embodiment of the invention, the display control of the LED display screen is realized, and the display content of the LED display screen is finer.

Description

technical field [0001] The invention relates to the technical field of LED display control, in particular to a display control method and system for an LED display screen. Background technique [0002] The LED display screen is an electronic display screen composed of LED dot matrix. By turning on and off the traffic light beads to replace the screen display content forms such as text, animation, pictures, and video, the timely conversion is performed, and the component display control is performed through a modular structure. It is mainly divided into display module, control system and power supply system. The display module is a dot matrix of LED lights to form a screen to emit light; the control system is to control the on and off conditions in the area to convert the content displayed on the screen; the power system is to convert the input voltage and current to meet the needs of the display screen; but In the existing display control of LED display screens, there is st...
