Abstract

2-inch qVGA (240${\times}$320) TFT-LCD with integrated 6-bit source driver is reported. The pixel density is over than 200ppi and the operation frequency is about 2.8MHz. In order to improve TFT characteristics, TS-SLS (Two-Shot Sequential Lateral Solidification) technology has been employed. A 1:6 demultiplexing scheme has been successfully implemented in the source driver owing to the superb characteristics of the TS-SLS TFTs, which resulted in small driver circuit area.
