Abstract:
A liquid crystal display (LCD) panel assembly comprising:a first panel; a second panel; and an LCD layer sandwiched therebetween, said first panel including: a first substrate; a plurality of pixel elements arranged in a matrix on said first substrate, each said pixel element including a thin film transistor (TFT), a pixel electrode and a common electrode, said pixel electrode and said common electrode generating therebetween a lateral electric field parallel to a surface of said first substrate; a plurality of common electrode lines each connected to corresponding common electrodes; a plurality of scanning lines each disposed for a corresponding row of said pixel elements and connected to gates of said TFTs in the corresponding row; and a plurality of video signal lines each disposed for a corresponding column of said pixel elements and connected to source/drain paths of said TFTs in said corresponding column, said common electrode lines forming a plurality of groups each corresponding to said pixel elements having an equal total capacitance between said pixel electrode and said common electrode in the pixel elements, each of said groups being applied with a separate voltage independently of voltages applied to another of said groups.
