摘要： PROBLEM TO BE SOLVED: To reduce the loss in the output stage, and to realize small power consumption not only in a data driver but also in the whole of a liquid crystal display. SOLUTION: When a set signal becomes "H", a voltage Vgs(pre) is held in an input capacitor Cin so that a nMOS transistor 20 holds the source voltage Vin by the drain current I1. When the set signal becomes "L" and a write signal becomes "H", then the nMOS transistor 20 performs a source follower operation while charging a load capacitor Cload and becomes stable. Both of the set signal and the write signal become "L" at the timing of terminating a writing process into the load capacitor. A write voltage is held in the load capacitor hereinafter. Concurrently, the power consumption becomes zero because minute bias current 11 is reduced completely by compulsorily turning off the power sources 21, 22. COPYRIGHT: (C)2004,JPO&NCIPI
