  • Patent number: 9897831
    Abstract: A blue phase liquid crystal panel includes a plurality of pixel cells. Each of the pixel cells comprises a display area and a viewing angle controlling area. The viewing angle controlling area includes a plurality of first electrode pairs spaced apart from each other, and each of the first electrode pairs includes a first pixel electrode1 and a first common electrode. In a wide viewing angle mode, no electrical field is generated by the first electrode pair of the viewing angle controlling area. In a narrow viewing angle mode, a vertical electrical field is generated between the first pixel electrode and the first common electrode of each of the first electrode pairs within the viewing angle controlling area. In this way, the liquid crystal panel may transit between the wide viewing angle mode and the narrow viewing angle mode.

  • Patent number: 9897872
    Abstract: Disclosed is a liquid crystal display panel with a switchable viewing angle and a driving method thereof. A pixel unit located in a display area of the liquid crystal display panel comprises: a main pixel region, which is horizontally aligned, wherein pixel electrodes and common electrodes are alternately arranged on the lower substrate and spaced from one another; and a sub-pixel region, which is perpendicularly aligned, wherein upper substrate electrodes and corresponding pixel electrodes are arranged below the upper substrate and on the lower substrate, respectively. When no bias voltage is applied to the upper substrate electrodes in the sub-pixel region, liquid crystal molecules corresponding to the sub-pixel region do not deflect, such that large viewing angle light leakage occurs in the sub-pixel region, thereby achieving narrow viewing angle display.
