Paper Abstract

In this paper, the author conducted the research how to measure automatically the image point homogeneity of the high density matrix LED display, gave the measuring plan of the integrating sphere-photoelectric multiplex tube, manufactured the device which measured automatically the image point homogeneity of the matrix LED display. Because the device adopted MCS-51 microcomputer on chip for controlling system, quick and automatical measurement was realized. The device had the function that information was exchanged between user and computer so as to measure all kinds of high density matrix LED display. After correcting the measuring error, the precision of complete set of measurement equipment was up to 1.7%.
