Control circuit for liquid crystal display panel, test equipment and test method

The invention provides a control circuit for a liquid crystal display panel, a test device and a test method. The control circuit includes a current sensor and a discharge signal generation circuit. The current sensor is used for detecting the change of the input current of the liquid crystal display panel to generate an indication signal, and the indication signal indicates the switching of the image frames displayed by the liquid crystal display panel. The discharge signal generation circuit is used for receiving the indication signal from the current sensor and generating a discharge signalin response to receiving the indication signal, so that a liquid crystal capacitor formed by a common electrode and a pixel electrode in the liquid crystal display panel discharges. Therefore, the quality of images displayed by the liquid crystal display panel can be improved, and the product yield is improved. 提供了一种用于液晶显示面板的控制电路、测试设备和测试方法。控制电路包括电流传感器和放电信号生成电路。电流传感器用于检测所述液晶显示面板的输入电流的变化而产生指示信号，所述指示信号表明液晶显示面板所显示的图像帧的切换。放电信
