Abstract

The present application provides a signal source backup method, device, system, and LED controller. The signal source backup system includes a distributor and an LED controller, wherein: the distributor is used to receive the signal input by the signal source, and The above-mentioned signals are respectively output to multiple signal input ports of the LED controller through multiple signal source channels; the LED controller is used to receive a signal from one of the signal input ports when a signal is detected from the signal input port. The received signal is output to the LED screen. This solution can improve the reliability of the LED screen.

Description

technical field [0001] The present application relates to LED (Light Emitting Diode, light emitting diode) technology, in particular to a signal source backup method, device, system and LED controller. Background technique [0002] During the normal display process of the LED signal source, if the source input channel of the LED controller (also called the sending card) fails, it will cause the LED screen to be unable to display normally for a long time, affecting the normal use of the user. Contents of the invention [0003] In view of this, the present application provides a signal source backup method, device, system and LED controller. [0004] Specifically, this application is achieved through the following technical solutions: [0005] According to the first aspect of the embodiments of the present application, a signal source backup system is provided, including a distributor and a light-emitting diode (LED) controller, wherein: [0006] The distributor is used to...
