Abstract:
1. A device for reducing flickers of a liquid crystal display panel, the liquid crystal display panel being divided into a plurality of blocks, the device comprising: a memory for storing a plurality of initial codes, wherein each initial code corresponds to a block of the plurality of blocks and a common voltage, a plurality of common voltages corresponding to the plurality of blocks being distinct; a common voltage generation unit; and a controller for generating a control signal to the common voltage generation unit when the controller starts to count scan start signals corresponding to the block; wherein the common voltage generation unit reads the initial code from the memory according to the control signal, and generates the common voltage to the block according to the initial code; and wherein each of the common voltages substantially equals to an average of a positive feed through voltage and a negative feed through voltage of a corresponding block.
