Description

Technical Field

[0001] The utility model relates to the technical field of LED control card interface testing, in particular to an LED control card interface testing device. Background Art

[0002] Currently, small and medium-sized display screens are basically driven by FPGA plus decoder due to their large loading area and large number of scanning points. FPGA has many pins, so it needs a large number of resistors, electronic components and cable bases to be connected. In actual production, due to the defective rate of components and defects in processing technology (such as cold soldering), there is a probability that a pin will have poor connectivity with the cable base, resulting in poor display effect of the actual LED display screen.

[0003] In production testing, it is necessary to use the LED control card interface test device to plug and unplug the LED control card and the test connector multiple times, and then use a static tester to detect the data transmission of the LED control card to test its interface life.
