Abstract

An electronic performance testing system is designed for the TFT LCD.The visual parameter configuration and wireless control are realized for the dust-free workshop and variable drive waveform.The timing and amplitude parameters of testing waveform are configured by the upper computer.The waveform parameters are transferred to the data receive module in the lower computer by the series port.And then,the parameters in the lower computer are sent to the TFT LCD drive circuit module.The single chip is utilized in the TFT LCD drive circuit module to generate the corresponding output waveforms.The testing system has been applied to the LCD manufacturers,and the visual parameter configuration and wireless control have been accepted by the dust-free workshop.
