Metal Induced Continuous Grain Polycrystalline Silicon Thin Film Transistors and Its Application for Field Sequential Color-Liquid Crystal Display (FSC-LCD)

摘要

Metal induced polycrystalline silicon (poly-Si) films composing of continuous zonal domain (CZD) have been obtained through pre-defined crystalline nucleation lines. The crystallization process is precisely controllable and the annealing time can be shorter than one hour. P-channel thin film transistors (TFTs) built on CZD poly-Si present high performance and high uniformity. In this paper, we also demonstrate the application of CZD TFT to fast addressing active matrix field sequential color-liquid crystal display (FSC-LCD). A prototype display panel has been fabricated. Large aperture ratio, excellent color purity and fast moving image can be obtained.
