A high gray scale TFT-LCD drive system

Abstract

This paper describes a new drive method of TFT-LCD for high gray scale display. The method is based on Rotating Ordered dithering algorithm and frame modulating technology. This method can use low-bit gray scale TFT-LCD panel to realize a high gray scale display. This method is applied to a 1280*1024 dots RGB 6-bit TFT-LCD panel which can display 256-level gray scale.
