| Abstract: | A top-down design methodology is proposed for the design of TFT-LCD one-chip driver Ics,and a 260k color,176RGB× 220-dot TFT-LCD one-chip driver IC is successfully developed with silicon verification. This IC is a typical mixed-signal VLSI and is implemented by a 0.18μm HV CMOS process. The static power dissipation is about 5mW for 260k color display mode,and the settling time of the output grayscale voltages within 0. 2% error is less than 26μs. |
