    • A detection circuit and a detection method for liquid crystal display are provided. The detection circuit comprises gate driver for providing row scan signal to liquid crystal cell to be detected; signal source for providing polarity inversion signal to source driver, polarity inversion signal comprises continuous high level signal and continuous low level signal; source driver for performing digital-analog conversion on received display data signal according to preset reference voltage and polarity inversion signal, generating pixel voltage signal, and sending pixel voltage signal to liquid crystal cell to be detected, polarity inversion mode formed by pixel voltage signal is column inversion mode. The polarity inversion mode of column inversion, formed by pixel voltage signal in technical solution makes white dot of damaged area of alignment film is more prominent during detection process, so it would be easy for the operator to recognize it and avoid the issue of missing detection.
    • 提供了用于液晶显示的检测电路和检测方法。 检测电路包括用于向要检测的液晶单元提供行扫描信号的栅极驱动器; 用于向源极驱动器提供极性反转信号的信号源,极性反转信号包括连续高电平信号和连续低电平信号; 源驱动器,根据预置的参考电压和极性反转信号对接收到的显示数据信号进行数模转换,产生像素电压信号,并将像素电压信号发送到要检测的液晶单元,由像素电压信号形成的极性反转模式为 列反转模式。 在技​​术方案中由像素电压信号形成的列反转极性反转模式使得检测过程中取向膜损伤区域的白点更加突出,因此操作者很容易识别,避免了检测失误的问题 。
