Abstract

The invention belongs to the wireless transmission and LED display control technology field, in particular to a distributed type wireless LED display system. The display system is composed of a wireless controller and a plurality of wireless display boards. The wireless display boards preset pre-displayed picture information before being used, each wireless display board displays a pixel point of a whole picture, and a complete picture is formed by all the wireless display boards together. When the invention is used, synchronous control signals transmitted through the wireless controller are received, a pre-displayed picture is started, and thereby the effect that each wireless display board synchronously displays the pre-stored pictures is achieved. The system adopts the distributed type design and the centralized wireless control, the application field is extremely wide, such as the auditorium dynamic picture displaying and the athlete square matrix dynamic showing of large-scale sport meetings and concerts, etc.

Description

technical field [0001] The invention belongs to the technical field of wireless transmission and LED display control, in particular to a distributed wireless LED display system. Background technique [0002] In recent years, with the rapid development of China's economy, culture, and sports, various large-scale cultural, sports, and scientific and technological events have been held continuously. The holding of these events has put forward various new demands for on-site publicity methods. Among them, the various on-site demonstration activities participated by the audience are still in the backward fixed demonstration mode stage, that is, each audience holds a fixed-color luminous stick or colorful flag to display a fixed combination of graphics, and requires prior rehearsal and on-site command to achieve Displays the purpose of a particular composite graphic. This method has been difficult to meet the high-tech needs of various events. Contents of the invention [0003...
