Design solution and implement of medium size digital TFT-LCD panel test device based on FPGA are introduced. Key points and implement of hardware and software design
for driver timing generator
V
COM
and Gamma reference voltage generator and PWM dimming with keys
are described in detailed. It is verified
by the timing simulation and experiment that the test device can display monocolour
gray scales
cross-talk
flicker common patterns clearly and steadily
and can meet needs in the production for the defect detection
optical performance test and analysis. It is flexible to use
