43.1: A Novel Multi‐level Memory in Pixel Technology for Ultra Low Power LTPS TFT‐LCD

A Novel multi-level memory in pixel technology is proposed for ultra low power TFT-LCD, which can realize the multi-color using the analog voltage grey-scale method. This technology is successfully implemented into the transflective 4 grey-scale (64 colors), 3.17 inch HVGA panel with low power of 300uW and high quality of image.
