Abstract
An apparatus for recycling energy in a liquid crystal display (LCD) so as to reduce energy loss when the LCD is driven by a driving circuit. The LCD includes two pixels, each of which has a corresponding capacitor and has a corresponding voltage applied to. The polarities of the voltages of the two corresponding capacitors are variable with time and are opposite to each other. The apparatus includes two switches and an energy converter. The two switches are used for selectively coupling the respective capacitors to the apparatus. The energy converter is used for outputting converted energy according to the voltages of the two capacitors. By enabling the first switch and the second switch selectively, the apparatus recycles energy dissipated during polarity inversion for the two pixels as energy for driving a load device.
