Abstract: An in-plane switching mode liquid crystal display (IPS-LCD). A plurality of lengthwise-extending common electrodes are formed in each pixel area, and each common electrode has a curved or zigzag profile. A plurality of lengthwise-extending pixel electrodes are formed in each pixel area, and each pixel electrode has a curved or zigzag profile. The pixel electrodes are disposed in the intervals between the common electrodes, and two adjacent pixel and common electrodes form a subpixel area. Liquid crystal molecules are positioned within each sub-pixel area. The two adjacent pixel electrode and common electrodes within each sub-pixel area are not parallel to each other, and thus a gradient in-plane electric field is generated therebetween.

Abstract: A liquid crystal display includes a first substrate including a first electrode; a second substrate including thereon a second electrode having at least one elongate hole having a longitudinal direction and facing to the first electrode; a third electrode positioned under the at least one hole and between the second electrode and the second substrate; and a liquid crystal layer comprising a plurality of liquid crystal molecules and interposed between the first substrate and the second substrate. The third electrode has a bias voltage being two volts higher than a pixel voltage of the sub-electrode.

Abstract: An array structure of a liquid crystal display is provided, comprising a substrate having a first and a second pixel region thereon. Each of the pixel regions has a transistor, a pixel electrode electrically connected to a drain of the transistor, and a common electrode forming a capacitance with the pixel electrode, wherein the common electrodes of the first and second pixel regions are electrically isolated from each other.

Abstract: An electrode array of IPS-LCD has a comb-shaped common electrode made by patterning a bottom-metal layer, respectively disposed and a comb-shaped pixel electrode made by patterning an inter-metal layer, and a connecting layer made by patterning a top-metal layer. The comb-shaped common electrode has a bar and a plurality of comb-teeth extending in a first Y-direction. The comb-shaped pixel electrode has a bar and a plurality of comb-teeth that extend in a second Y-direction and are inter-digitated with the comb-teeth of the common electrode. The connecting layer is electrically connected to one end of the comb-teeth of the pixel electrode and covers part of the bar of the common electrode. In addition, two strip-shaped metal-shielding layers made by patterning the top-metal layer are disposed over the comb-teeth of the common electrode to eliminate crosstalk.

Abstract: The invention describes new biphenyl dianhydrides, and new polyimides and copolyimides made from the dianhydrides. The synthesized polyimides exhibit significantly enhanced solubility when the biphenyl dianhydrides are substituted, particularly at the 2 and 2' positions on the phenyl rings.
