  • Patent number: 8553051
    Abstract: A liquid crystal display (LCD) includes an LCD panel, a scan driver, a timing controller and a data driver. The LCD panel includes first and second pixel rows. The timing controller determines a correction voltage index according to an absolute difference between an average of original pixel voltages corresponding to original pixel data of all pixels of the first pixel row, and an average of original pixel voltages corresponding to original pixel data of all pixels of the second pixel row, determines a correction voltage according to the correction voltage index, determines an adjusted pixel voltage in a target pixel according to an original pixel voltage of the target pixel in the second pixel row and the correction voltage, and outputs adjusted pixel data corresponding to the adjusted pixel voltage. The data driver outputs the adjusted pixel voltage to the target pixel according to the adjusted pixel data.

  • Patent number: 7978211
    Abstract: In a liquid crystal display (LCD) device, a plurality of pixels is driven to display a first frame and a second frame in sequence. A gray-scale difference between the first frame and the second frame is detected to determine a driving mode variation between the first frame and the second frame. The number of pixels driven by a dynamic mode and a static mode in the second frame is adjusted according to the driving mode variation. Gray-scale data corresponding to the pixels in the second frame is output.

  • Patent number: 7852305
    Abstract: A flat panel display includes pixel electrodes, multiplexers and a gate driver. The gate driver has an amorphous silicon gate structure and includes a displacement temporary storage unit having a plurality of shift registers each with a power supply source and a clock terminal. One of a first voltage and a second voltage is selected and transmitted to the power supply source, and one of the first voltage and a clock signal is selected and transmitted to the clock terminal according to an off-controlling signal for causing the pixel electrodes connected to the shift registers to discharge.
