21.4: Development of SLS-Based System on Glass Display

2-inch qVGA (240×320) TFT-LCD with integrated 6-bit source driver is reported. TS-SLS (Two-Shot Sequential Lateral Solidification) technique has been employed to improve the TFT characteristics. Thanks to the superb characteristics of the TS-SLS TFTs, 1:6 de-multiplexing driving scheme has been successfully implemented in the source driver, which resulted very compact circuit area and the highest resolution (200ppi) SOG (System on Glass) display ever reported.
