When in the Cell process of an LCM Testing solution various defects can be inspected by shorting-bar signals and repaired by laser. Based on the panel sizes and backlight features (CCFL or LED BLU) in the LCM process, the tests of LCM voltage, current and power can be used to analyze the image's lit pixel, dead pixel, color and resolution with the application applied to both software and hardware via the video signal source plus programmable power supply and friendly user interface on PC platform. The solutions not only can incorporate automatic conveyor as a design of production line, but also has integrated network management function for data collection and analysis.
