VIEWING ANGLE CONTROL METHOD OF THE FRINGE-FIELD SWITCHING LIQUID CRYSTAL DISPLAY

摘要

A method for adjusting the viewing angle of an FFS(Fringe-Field Switching) LCD is provided to suitably implement a broad viewing angle and a narrow viewing angle by using two transistors in a pixel so that a vertical electric field and a fringe electric field can be applied to a viewing angle driving region and a pixel driving region respectively. An FFS LCD comprises a lower substrate, the first common electrode(1), an insulated layer, the first pixel electrode(2), the second pixel electrode(3), a liquid crystal layer, an upper substrate, and the second common electrode(4). The first common electrode(1) is patterned on the lower substrate in a plane form. The insulated layer is located between the lower part of the first common electrode(1) and the first and second pixel electrodes(2,3). The first pixel electrode(2) is transversely patterned on a portion of the upper part of the insulated layer in a latticed form. The second pixel electrode(3) is patterned on the other portion of the upper part of the insulated layer in a plane form. The liquid crystal layer, horizontally arranged, is located at the upper parts of the first and second pixel electrodes(2,3). The second common electrode(4) having the same size as the second pixel electrode(3) is patterned on the upper substrate in a plane form.
