摘要

针对生产车间无尘化及驱动波形多样化的特点

设计了一种测试参数可视化设置、具备无线控制功能的TFT LCD电性能检测系统。测试波形的时序和幅值等参数通过上位机进行设置

上位机将这些参数通过串口传给下位机的数据接收模块

数据接收模块通过无线传输模块发送到TFT LCD驱动电路模块

驱动电路模块利用单片机控制产生相应的驱动波形。厂家的应用结果表明

该系统的测试参数可视化设置和无线控制功能满足了现代车间的无尘化的要求。

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.
