Abstract

The invention discloses a control system for a lifting LED display screen. The control system comprises multiple display units arranged on guide rails, receiving cards arranged on the display units, sending cards arranged on a control chamber of the LED display screen, and a video player. Each display unit comprises multiple LED light bars and a truss and further comprises distance sensors, a speed sensor and proximity switches. The sending cards are used for receiving video information sent by the video player and converting the video information into a mode recognized by the receiving cards. The receiving cards are used for sending the video information to the LED light bars so as to be displayed. The sending cards can control the LED display screen according to information of the speed sensors, the distance sensors and the proximity switches, the LED display screen can be kept in a non-working state in the ascending and descending processes, a lifting system and a display system cannot work at the same time, and flexibility and safety of the lifting LED display screen are improved.

Description

technical field [0001] The invention belongs to the application field of LED electronic products, and in particular relates to a control system for a liftable LED display screen. Background technique [0002] LED display control system (LED Display Control System), also known as LED display controller, LED display control card. It is the core component of the LED display screen. It is mainly responsible for receiving the screen and video display information from the computer serial port or DVI interface, putting it into the frame memory, and generating serial display data that the LED display screen can recognize according to the partition drive mode. and scan control timing. [0003] The control system includes asynchronous control and synchronous system [0004] LED display asynchronous control system is also called LED display offline control system or offline card. It is mainly used to display various texts, symbols and graphics or animations. The information display...
