Abstract
An electrode array structure in a pixel area of a fringe field switching mode LCD (FFS-LCD). A comb-shaped common electrode includes a first bar extending in a first direction and a plurality of first teeth extending in a second direction from the first bar, wherein each first tooth comprises a first bone having a plurality of discontinuous first trapezoidal protrusions on each side thereof. A comb-shaped pixel electrode comprises a second bar extending in the first direction and a plurality of second teeth extending in the second direction from the second bar, wherein each second tooth comprises a second bone having a plurality of discontinuous second trapezoidal protrusions on each side thereof.
Claims21
An electrode array structure in a pixel area of a fringe field switching mode LCD (FFS-LCD), comprising:
- a common electrode comprising a first bar extending in a first direction and a plurality of first teeth extending in a second direction from the first bar, wherein at least one first tooth comprises a first bone having a plurality of discontinuous first trapezoidal protrusions on at least one side thereof;
- and
- a pixel electrode comprising a second bar extending in the first direction and a plurality of second teeth extending in the second direction from the second bar, wherein at least one second tooth comprises a second bone having a plurality of discontinuous second trapezoidal protrusions on at least one side thereof.
A fringe field switching mode liquid crystal display (FFS-LCD), comprising:
- a first substrate and a second substrate with a liquid crystal layer interposed therebetween;
- and
- a common electrode interdigitated with a pixel electrode formed on the first substrate, wherein an electrical field generated therebetween controls an orientation of liquid crystal molecules in the liquid crystal layer;
- wherein the common electrode comprises a first bar extending in a first direction, a plurality of first teeth extending in a second direction from the first bar and at least one first tooth comprises a first bone having a plurality of discontinuous first trapezoidal protrusions on at least one side thereof;
- and
- wherein the pixel electrode comprises a second bar extending in the first direction, a plurality of second teeth extending in the second direction from the second bar and at least one second tooth comprises a second bone having a plurality of discontinuous second trapezoidal protrusions on at least one side thereof.
