Title: OVERVOLTAGE DRIVE APPARATUS, STORAGE METHOD THEREFOR AND DISPLAY DEVICE APPLYING SAME
Abstract:
Disclosed are an overvoltage drive apparatus, a storage method therefor and a display device applying same. The overvoltage drive apparatus is applied to a liquid crystal display panel (118) for receiving a plurality of pixel gray-scale values corresponding to a pixel in a plurality of pictures and outputting a plurality of overvoltage driving gray-scale values according to the pixel gray-scale values. The overvoltage drive apparatus comprises: a pixel information processing unit (310) for identifying the color of a pixel; a first storage unit (330) for storing the pixel gray-scale values; a second storage unit (340) for storing difference values compared with the pixel gray-scale values stored in the first storage unit (330); and an overvoltage drive selection correspondence unit (320) electrically coupled to the pixel information processing unit (310), the first storage unit (330) and the second storage unit (340) separately and used for selecting the corresponding first storage unit (330) or the second storage unit (340) required by the pixel gray-scale values of the pixel according to the pixel color identified by the pixel information processing unit (310).
