High Density Reflective Type TFT Array for High Definition Liquid Crystal Projection TV System

Abstract

In order to develop a compact high definition TV (HDTV) set with liquid crystal projection technology, a new reflective TFT array is proposed. In addition, 2. 3 inch liquid crystal light valves (LCLVs) are fabricated, containing about 1. 36 million pixels.
Furthermore, a new driving method is also proposed which is concerned with not only the TFT array architecture but also with the driving scheme of the TFT array. From the experimental results of image quality of the LCLV projection system, this new method has been clarified to be effective for cancelling the cross-talk from the signal line to the pixels through the source-drain capacitance.
