Development of a 14.1‐in. UXGA TFT‐LCD using LTPS technology

A 14.1-in. UXGA low-temperature poly-Si TFT-LCD has been developed using p-MOS technology. Both the peripheral driving circuits and the pixel switches are implemented using only p-channel TFTs. The device performance for the driving circuits and the panel design issues, such as crosstalk and flicker, were investigated. The image quality required for the notebook-PC display has been achieved by optimizing the panel design and by improving the device performance. In addition, the redundant gate driving structure has been developed to minimize the degradation of the panel yield.
