LIQUID CRYSTAL DISPLAY PANEL DRIVING DEVICE AND LIQUID CRYSTAL DISPLAY

摘要

PROBLEM TO BE SOLVED: To provide a liquid crystal panel driving device capable of inexpensively and precisely performing DC-free AC driving of a liquid crystal display panel and a liquid crystal display using the same. SOLUTION: The liquid crystal panel driving device has a reference voltage generating unit provided with a serial unit including a plurality of resistors connected in series, a first switch for supplying a first potential in a first mode and a second potential in a second mode to a terminal of the serial unit and a second switch for supplying the second potential in the first mode and the first potential in the second mode to the other terminal of the serial unit for outputting voltages from connection points between the plurality of resistors and a driving unit for selectively outputting any one of the plurality of voltages according to a value of image data for applying the voltage to a terminal of a pixel of a liquid crystal display panel.
