52.2: A Low‐Cost Stable Amorphous Silicon AMOLED Display with Full VT‐ and VOLED Shift Compensation

We present a new simple and low cost pixel circuit and driving scheme for the a-Si AMOLED displays using conventional AMLCD drivers. Measurement results show significant stability and high immunity to temperature and mobility variations which makes the pixel circuit and driving scheme attractive for implementation in different technologies. A 9-inch a-Si AMOLED display fabricated based on this driving scheme shows high uniformity and long lifetime.
