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.

Control circuit, testing apparatus and method for liquid crystal display panel

A plug device for automatically plugging a display panel and a connector comprises a first linkage having a fixed end and a movable end that can approach or get away from the display panel at a plug location. The connector comprises a first connector head, a second connector head and a wire that connects the first and second connector heads, the connector is mounted on the first linkage, the first and second connector heads of the connector are respectively secured on the movable end and the fixed end of the first linkage. The second connector head is connected with a signal generator, and when the movable end approaches the display panel at the plug location, the first connector head is automatically plugged on the display panel. The plug device may be used in a method of automatically plugging a display panel with a connector.
