Abstract: An exemplary discharge circuit (220) includes a first input terminal (2202); a transistor (2204) having a gate electrode, a drain electrode, and a source electrode; a resistance (2205); and a control circuit (2203) provided to control a voltage applied to the gate electrode of the transistor. The source electrode of the transistor is connected to the first input terminal, and the drain electrode of the transistor is grounded via the resistance. Electric charge from the first input terminal is discharged through the transistor and the resistance under control of the control circuit. A liquid crystal display (LCD) (2) employing the discharge circuit exhibits few or no residual images.

Abstract: A driving circuit (25) for a liquid crystal display connecting to a host is provided. The driving circuit includes an image memory (251), a comparator (253), a counter (255) and an image converting means (259). The image memory stores a former frame's image data. The comparator compares a latter frame's image data provided by the host with the former frame's image data. The counter has a predetermined first threshold value and is configured to record an ongoing number of consecutive frames during which a latter frame's image data are the same as a former frame's image data. The converting means inverts a latter frame's image data into inverted frame image data when the ongoing number reaches the first threshold value.
