  • Column electrode driving circuit and voltage generating circuit for a liquid crystal display
    Publication number: 20050078077
    Abstract: An object of the invention is to provide a column electrode driving circuit and a display device using it, which can reduce power consumption. A column electrode driving circuit 50 for a display device capable of gray-scale displaying. This circuit 50 comprises: gray-scale voltage producing means (2) including amplifiers (A63-A0) whose inputs are applied with a plurality of gray-scale voltages (V63-V0), respectively; and selecting means (30-3x) for selecting and outputting any of output signals (#63-#0) of the amplifiers (A63-A0) for each pixel or each predetermined displayed unit in accordance with an image signal indicative of a gray-scale level for the pixel or displayed unit. The gray-scale voltage producing means 2 causes any amplifiers (A1-A3, . . . , A56-A58, A60-A62) of the amplifiers, which correspond to a predetermined number of predetermined gray-scale levels, to be powered off and causing the other amplifiers (A0, A4, . . .
