Patent ID: 8013829

Claim:
A liquid crystal display, comprising: a liquid crystal panel comprising a plurality of pixels; a data circuit configured for driving the pixels; and a black insertion controller configured for controlling the data circuit to provide corresponding driving voltages for the pixels, the black insertion controller comprising a plurality of black insertion control units each having a control signal generator, the control signal generator being configured to generate a black insertion control signal and comprising a memory member, a selector member, and a multiplexer, the selector member reading data stored in the memory member according to an address of the pixel, and the multiplexer generating the black insertion control signal according to the data read by the selector member; wherein the black insertion controller receives a display signal of the pixel, and generates the black insertion control signal according to the address of the pixel, the data circuit drives the pixel to display one of a black image unit and a normal image unit according to the first black insertion control signal in a first sub-frame period of a frame period, and the displayed black image unit of the pixel or the displayed normal image unit is converted into a normal image unit or a black image unit in a second sub-frame period of the frame period.
