Paper Abstract

Low Temperature Poly-Silicon (LTPS) TFT technology for LCD has been developed for a long time. Because of its higher mobility, scan driver and data driver could be fabricated on the glass panel to form a fully integrated display panel and reduce its cost. In this paper, new circuits for buffering the DAC in the data driver will be proposed. These circuits have the advantages of lower power and smaller area than the conventional ones. They all extend their full swing from 2 to 10 volts in 12 us and have 6-bit resolution at least. Furthermore, the circuits have no feedback system as the operational amplifier does, which is hard to design in the current LTPS technology.
