Design of interface circuit system based on S3C2440 for photoelectric parameters detection of liquid crystal display devices

Abstract

An interface circuit system based on S3C2440 and VC++6.0 for photoelectric parameters detection of liquid crystal display(LCD) devices is designed. The system can detect the photoelectric parameters of various types of LCD devices commonly used in the market, not need to replace more other driver power and driver signal source and other equipment with different models, and can transmit the effective data to PC through the communication interface. The trouble caused by replacement and complex wiring of various equipment and instruments in the detection of photoelectric parameters of LCD devices is solved. The results show that the system is stable, easy to operate, simple to connect, and has high accuracy of data acquisition.
