Abstract

The invention relates to an LED lamp panel, a tail end terminating module, an LED control card and an LED display system. A channel selection circuit is arranged on the LED lamp panel, a data storing, reading, writing, inputting and outputting circuit is arranged on the tail end terminating module, an input and output marking signal is generated by the LED control card in a matched mode to control the functions of a data wire on the LED lamp panel at different moments, and time multiplexing of the data wire is achieved. Thus, return of detected data is achieved under the condition of not influencing load of the LED control card, performance of the LED control card is optimized, the performance index of the LED control card is greatly improved, and meanwhile the detection function of the lamp panel is achieved.

Description

technical field [0001] The invention relates to the technical field of display control, in particular to an LED lamp board, an end terminal module, an LED control card and an LED display system. Background technique [0002] LED (Light Emitting Diode, Light Emitting Diode) display system, as a new type of display technology, is gradually accepted by the market due to its advantages of energy saving, environmental protection, and high brightness, so it is widely used in urban media, urban transportation and other fields. [0003] Among them, the LED display system in the traffic field is generally used to display information such as road names, traffic conditions, and speed limits. Every LED light point on the LED display may fail. When the number and location of LED light point failures reach a certain level , it will affect the display of information, and in serious cases, it will convey wrong information. Therefore, how to enable the LED display system in the traffic fiel...
