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.

A signal compensator includes an abnormality identification unit and a signal compensation unit. The abnormality identification unit is configured to determine whether or not a waveform of a signal generated by a signal generator is abnormal, when the waveform of the signal is normal, output the signal to a display panel, and when the waveform of the signal is abnormal, stop outputting the signal to the display panel and send an instruction to the signal compensation unit. The signal compensation unit is configured to perform signal compensation on the display panel in accordance with the instruction received from the abnormality identification unit.

Signal compensator, signal compensation method and signal compensation system for determining and compensating signal from signal generator to display panel

Embodiments of the disclosed technology provide a detecting device for recovering of release film and a recovery apparatus for release film. The recovery apparatus comprises clips for gripping release film, the detecting device comprises: a detecting sensor; a mobile module coupled onto one clipping arm of the clip. When the release film is gripped by the clip, the release film shifts the mobile module to a first position where the mobile module portion enters the detection scope of the detecting sensor; when the release film is not gripped by the clip, the mobile module shifts to a second position, where the whole mobile module portion withdraws out of the detection scope of the detecting sensor.
