Abstract: A control circuit, a testing apparatus and a method for testing a liquid crystal display panel are provided. The control circuit includes a current sensor and a discharge signal generation circuit. The current sensor is configured to detect a change in an input current of the liquid crystal display panel to generate an indication signal, the indication signal being indicative of switching of image frames displayed by the liquid crystal display panel. The discharge signal generation circuit is configured to receive the indication signal from the current sensor, and the discharge signal generation circuit generates a discharge signal in response to receiving the indication signal, so that a liquid crystal capacitor including the common electrode and the pixel electrode in the liquid crystal display panel is discharged. Hence, the quality of images displayed by the liquid crystal display panel can be improved and the product yield can be increased.
