LCD / LCM Testing Instruments


LCD Shorting Bar Pattern GeneratorFrom array, cell to module, the LCD process first goes through a series of chemical, physical processes and assembly procedures followed by carrying driver IC, circuit board and backlight units to form an LCD Module.


Aside from Cold Cathode Fluorescent Lamp (CCFL), low voltage, long life, mercury-free LED Back Light Units are a new trend in today’s LCD technology. When in the cell process of an LCM testing solution, various defects can be inspected by shorting-bar signals and repaired with lasers. 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 an images lit pixel, dead pixel, color and resolution with both software and hardware using a video signal source plus programmable power supply administered by a user-friendly PC interface. This solution not only incorporates an automatic conveyor production line, but also utilizes integrated network management for data collection and analysis.
