Abstract

New charge-recycling structure and driving scheme for TFT-LCD source-driver IC application are proposed. The number of additional switches for the charge recycling is greatly reduced. An experimental prototype 6-bit source driver with five-level sevenphase charge recycling implemented in a 0.35-μm CMOS technology demonstrates that the quiescent current is only 3.1 mA, dynamic power saving is 75%, and the settling time, which includes the charge-recycling and data driving, is within 25 μs.
