A 550-PPI LCD using 1.5 µm channel width LTPS TFTs with low frame rate driving

A 550 PPI low-temperature polycrystalline silicon thin-film transistor liquid-crystal display has been developed. Shrinkage of the channel width of pixel thin-film transistor together with thinner insulator for the storage capacitor allows high display quality in terms of vertical cross-talk and flicker. Thirty hertz frame rate driving is implemented to offer low power while keeping high display quality.
