  • Patent number: 8743106
    Abstract: By way of enabling a reset signal while turning off a liquid crystal display, a method for decaying residual image of the liquid crystal display is capable of setting the corresponding gate signal of each of a plurality of gate lines of the liquid crystal display based on the reset signal being enabled. Accordingly, enhanced discharging processes on all the storage units of the liquid crystal display for fast decaying residual image can be performed via the data switches of the liquid crystal display turned on by the gate signals being set. The reset operation for performing discharging processes in response to the reset signal can be carried out based on a reset circuit for setting all the gate signals to become high-level signals, or based on a charging/discharging module for furnishing a high-level voltage directly to all the gate lines.

  • Patent number: 8711077
    Abstract: An LCD device is configured to drive a plurality of shift register units using two clock signals having different driving abilities. Each shift register unit may thus generate a stronger signal for triggering a next-stage shift register unit, thereby improving cold-start. When the LCD device has been activated over a predetermined period of time, the driving ability of the clock signal having higher driving ability is gradually lowered, thereby reducing power consumption.

  • Patent number: 8497832
    Abstract: A flat panel display, a shift register with image retention release and method for releasing image retention are provided. An output end of the shift register couples to a gate line of a display panel. A first end of a first transistor couples to the output end of the shift register. A second end of the first transistor couples to a system voltage VDD or a reference voltage VSS. A first end of a capacitor couples to a control end of the first transistor. A second end of the capacitor couples to the reference voltage VSS. During a power-off period, the reference voltage VSS is pulled high for turning on the first transistor, therefore the voltage of the gate line is pulled high.
