Abstract

The embodiment of the invention discloses a wireless LED spliced screen and a control method and system. The wireless LED spliced screen and the control method and system are used for solving the technical problems that as the temperature inside a tank of a display module rises, flat sequence confluence cables age or short-circuit, defective flat cables are difficult to find in an anfractuous circuit, and labor is wasted, and also avoiding the technical problem that due to the errors of the video data transmission sequence caused by the number and arrangement complexity of display units, the overall picture of a spliced screen shifts and deforms. The wireless LED spliced screen is formed by splicing a plurality of display units, a main control module of each display unit is connected with a wireless module, and the wireless modules and the display units are in one-to-one identifier binding relation.

Description

technical field [0001] The present invention relates to the field of LED technology, in particular to a wireless LED splicing screen, a control method and a system. Background technique [0002] The LED display splicing screen is usually spliced ​​by several display units (tiles). Each display unit can be mounted with several LEDs. The size of each display unit is, for example, 12*12cm. 4 display units form a box, and finally a large display is assembled by multiple boxes. [0003] Since each display unit needs to be serially connected through a serial bus to realize signal transmission, at the same time, each cabinet also needs to be serially connected through a serial bus to realize the overall image presentation. However, after layer-by-layer serial connection, many serial buses are used in the closed space of the cabinet. After long-term use, the temperature in the cabinet will rise and the serial confluence flat cable will be aged or short-circuited, and it is not easy...
