  • Patent number: 9798199
    Abstract: A layer of liquid crystal material may be interposed between display layers. The display layers may include thin-film transistor circuitry having subpixel electrodes for applying electric fields to subpixel portions of the layer of liquid crystal material. Subpixels of different colors may have different shapes and may have different liquid crystal layer thicknesses. These subpixel differences may be configured to slow the switching speed of subpixels of a certain color relative to other subpixels to reduce color motion blur when an object is moved across a black or colored background. The subpixels may have chevron shapes. Subpixels of a first color may have chevron shapes that are less bent than subpixels of second and third colors. In configurations with varying liquid crystal layer thicknesses, the subpixels of the first color may have thicker liquid crystal layers than the subpixels of the second and third colors.

  • Patent number: 9798204
    Abstract: Disclination of an active matrix liquid crystal display device is reduced. Portions of pixel electrodes are formed so as to mutually overlap with a convex portion. If the height of the convex portion is too tall, the amount of light leakage increases due to liquid crystals orienting diagonally with respect to a substrate surface. (See FIG. 1C.) If the height of the convex portion is low, the disclination reduction effect is low. The optimal convex portion height is thus determined.
