Abstract:In this paper,the research how to measure automatically the image point homogeneity of a high density matrix LED display is summarized.Based on the measuring method of integrating sphere-photomultiple tube(IS-PMT),the device of automatical measuring of image point homogeneity of a matrix LED display has been de-veloped.The device adopts the MCS-51 microcomputer on chip to realize the functions of automatical measurement and to have a good interface between user and computer for measuring all kinds of high density matrix LED displays.After correcting the measuring errors,the precision of the measurement equipment is up to 1.7%.
Keywords:matrix display intensity homogeneity
