    • 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.

    • A liquid crystal panel comprises an active matrix substrate, an opposing substrate facing the active matrix substrate, and a liquid crystal layer disposed between the active matrix substrate and the opposing substrate. On the active matrix substrate, a plurality of parallel signal lines and a plurality of parallel scanning lines are arranged for forming a matrix of pixels called an active area. A plurality of pads are formed in outer-lead bonding areas located on the periphery of the active area, and are used for mounting driving devices. Each of the OLB areas is separately connected to one of fan-out areas including a plurality of leads. Each compensation capacitor with a predetermined capacitance is connected to each lead so as to minimize variation of RC delay effect between all leads.
    • 液晶面板包括有源矩阵基板,面向有源矩阵基板的相对基板和设置在有源矩阵基板和相对基板之间的液晶层。 在有源矩阵基板上,布置多条并行信号线和多条平行扫描线,以形成称为有源区的像素矩阵。 在位于有源区域周边的外引线接合区域中形成多个焊盘,并用于安装驱动装置。 每个OLB区域分别连接到包括多个引线的扇出区域之一。 具有预定电容的每个补偿电容器连接到每个引线,以便最小化所有引线之间的RC延迟效应的变化。
