  • Publication number: 20150084939
    Abstract: A method for reducing power consumption of a liquid crystal display system includes: a timing controller receiving an image signal of a frame; the timing controller generating a gate control signal and a source control signal according to the image signal; a gate driving circuit driving odd scan lines of a plurality of scan lines in turn and then driving even scan lines of the plurality of scan lines in turn according to the gate control signal; and a source driving circuit charging a plurality of sub pixels included in a liquid crystal panel through a plurality of data lines according to the source control signal, driving sequence of the plurality of scan lines, and data voltages corresponding to the image signal. Voltages of the plurality of data lines are switched one time at most, and a common voltage of the liquid crystal panel is a direct current voltage.

  • Publication number: 20090262053
    Abstract: The present invention includes a resistive module, the resistive module including a plurality of nodes and at least a resistive component. The plurality of nodes include an input terminal and an output terminal of the resistive module; the resistive component is electronically connected between the input terminal and the output terminal of the resistive module to thereby make the input terminal and the output terminal have a specified resistive value therebetween. In addition, the resistive component is electrically connected between two nodes of a node pair among the nodes, and each resistive component has a corresponding predetermined resistive value.
