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 seven-phase charge recycling implemented in a $0.35-{\mu}m$ 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 $25{\mu}s$.
