  • Patent number: 7221350
    Abstract: A method of reducing flickering and inhomogeneous brightness in an LCD. The method serially connects each scan line connecting a plurality of pixels in a row with a resistor to form a scan line circuit. The resistor is connected between the first pixel of the scan line and the voltage input terminal of the scan line, so that the gate voltage entering the TFT in the first pixel deforms. The voltage of the TFT decreases when it is turned off, minimizing screen flickering and inhomogeneous brightness due to the capacitor charge coupling effect between the first pixel and the last pixel on a scan line.
