<title>Self-scanned polysilicon (p-Si) active matrix liquid crystal (AMLCD) displays</title>

Abstract

The paper describes the structure and technology of active matrix liquid crystal displays (AMLCDs) and discusses the advantages of the AMLCD technology ocmpared with CRT technology. AMLCDs use microelectronic thin film transistors (TFTs) to produce bright, full-color images equal to those of CRTs in clarity and resolution. At the same time, color AMLSDs alleviate many problems associated with color CRTs, such as poor reliability in a severe environment, modest color performance in high ambient light, poor mean time between repair (five times less than that of AMLCDs), relatively great weight, and poor volumetric efficiency. The paper considers the AMLCD electronics and discusses the development of self-scanned poly-Si AMLCDs with integrated row and column (data and select line scanners) circuitry and 5-bit grey shade drivers. The integration of row and column and gray scale circuitry on glass will dramatically increase compactness and reliability and decrease AMLCD panel costs.
