Method and circuit for LCD panel flicker reduction
A method and circuit for LCD panel flicker reduction. The invention relates to an adjustment circuit to reduce an LCD panel flicker, wherein the LCD panel has a plurality of scan lines and a plurality of data lines. In one embodiment, the adjustment circuit includes a variable resistor, and a plurality of impedance adjustment devices, each with impedance and having a control terminal to be coupled with a DC voltage source through the variable resistor, a power terminal to be coupled with a common voltage source, and a scan line terminal to be coupled with a scan line, wherein the impedance of each of the impedance adjustment devices can be varied when the resistance of the variable resistor is varied. Each of the impedance adjustment devices in one embodiment has a transistor. The impedance of each of the impedance adjustment devices is much higher than the impedance of the corresponding scan line to allow the LCD to be operated at higher frequencies.
