Abstract

The invention discloses an LED module driving signal control device and an LED box body. The device comprises a signal distribution module which is used for receiving a signal and outputting a plurality of signals; a decoding module used for receiving the coded signal and outputting a selection signal; and a multi-path input / output switch module respectively connected with the plurality of LED modules and used for receiving the multi-path signals and selecting one path of signals matched with the selection signals according to the selection signals and outputting the selected path of signals to the corresponding LED modules. Through the embodiment of the invention, each path of signal on the signal distribution module can be respectively and freely controlled according to the driving signal and the coding signal so as to respectively control each LED module and achieve the effect of shunt control, and the user experience is good.

Description

technical field [0001] The invention relates to the field of electronic information, in particular to an LED module driving signal control device and an LED box body. Background technique [0002] Usually, a complete LED box generally includes a box frame, a power supply, a receiving card, an adapter board and multiple LED modules. The box frame is used as a support for the LED box to install and support the power supply, receiving card, The adapter board, LED module, and receiving card are used as the control unit on the LED box to control the signal control of multiple LED modules on one box. [0003] The existing receiving card can only perform synchronous control on the multiple LED modules it carries. For example, when a receiving card is loaded with 4 LED modules, when the receiving card sends a command to black screen, all four LED modules can only be blacked out, and it is impossible to control by a single LED module. bad.
