Abstract

This paper proposes a sense amplifier with non-volatile memory in order to improve the image quality of LCD by enhancing the matching of the driving voltages between the panel and driver. The sense amplifier having a wide sensing margin and fast response adjusts LCD driver voltage of display driver. The CSTN-LCD with the sense amplifier results improved image quality than that with conventional 6 bit column driver without it.
