Title: Liquid crystal driving device for controlling a liquid crystal panel and liquid crystal display apparatus

Abstract: A liquid crystal driving device for controlling a liquid crystal panel and a liquid crystal display apparatus. Reference voltages are generated in a data driver from input reference voltages, and reference voltages are selected in accordance with the settings of gray scale control registers thereby to control the gray scale voltages. The gray scale control registers can be set using a data bus for transferring the display data from a liquid crystal controller, and the gray scale control operation is performed by the liquid crystal controller in accordance with the image data
