Abstract :
A high-resolution full-color LCD with integrated digital interface data driver is a strong candidate for mobile Internet appliances. This paper describes a low-temperature poly-Si (LTPS) TFT driver with 5-V/6-bit interface applicable to 5-inch SVGA LCDs. To reduce the driver area overhead, an architecture of multiplexed resistor-string D/A converter followed by synchronized signal distributor with alternative output voltages is demonstrated.
