Chroma 27014 Flat Panel Display Tester is a complete testing solution that meets the Liquid Crystal Module testing requirements of a production line. With integrated video generator, multi-channel precision power supply and process control unit, the system allows a complete test of signal, pattern and electrical parameters of LCM through a PC or remote control box.

Software parameter interface allows the adjustments of Timing, Pattern and Power values to match the specifications of the LCM, followed by Program sequence scenario set t ing creat ing a comprehens ive and effortless testing environment. Features of the Chroma 27014 FPD Tester include:

Testing Program Sequences
Setting the parameters of Turn On/Turn Off, Timing, Pattern and OCP/OVP/UCP/UVP values according to the LCM specifications provides complete and accurate testing conditions.

Timing and Pattern Editing
With the standard VESA timings and patterns already bui l t into the sys tem, cus tom geometric patterns could easily be created by importing pictures with BMP file format or assembling icons as desired within the software; all is done conveniently with the embedded real-time preview function.

Programmable Power Module
The built-in programmable DC power source adjusts power to accommodate LCM control chip, driver chip and the backlight module. Real-time readings of voltage and current are displayed and monitored. Its unique design avoids the transmission voltage drop which ensures the measurement accuracy when performing LCM operating status analysis. Each output channel is equipped with over voltage/over current protection and programmable timing relationship for Power On/Off.
