In response to the problem of high manual detection intensity and low efficiency in LED display screens,this paper uses LabVIEW and IMAQ VISION toolkits to design a machine vision testing system for display screens.This system can detect the bright,dark,and characters of LED display unit boards,and can also detect whether the display status of the status display screen is correct.Experimental verification shows that the detection system can accurately complete the detec-tion of various test items on the display screen,while ensuring test coverage and improving the timeliness and accuracy.
