Metal-Induced Continuous Zonal Domain (CZD) Polycrystalline Silicon Thin-Film Transistors and Its Application on Field Sequential Color Liquid Crystal Display

摘要

Metal induced polycrystalline silicon (poly-Si) films composing of continuous zonal domain (CZD) have been obtained through pre-defined crystalline nucleation lines (CNL). The crystallization process is precisely controllable and repeatable. P-channel thin-film transistors (TFTs) built on CZD poly-Si present high performance and high uniformity. Based on this CZD poly-Si TFT technology, which provides fast addressing characteristics and a large aperture ratio, together with a fast liquid crystal mode, a field sequential color liquid crystal display (FSC-LCD) prototype is designed and fabricated successfully. Excellent color purity and fast moving image can be obtained.
