  • Publication number: 20090322798
    Abstract: A display includes pixels, each pixel including a first display region and a second display region. A controller controls driving of the first and second display regions of each pixel to set the gray scale levels of the first and second display regions based on an overall gray scale level to be shown by the pixel.

  • Publication number: 20090310076
    Abstract: In one embodiment of an invention concerning liquid crystal display devices, a first pixel electrode of a thin film transistor (TFT) array substrate may overlap a slit of a second pixel electrode of the TFT array substrate but not overlap another slit of the second pixel electrode. This may help induce a multi-domain electric field without having to precisely position a common electrode of a color filter substrate and the TFT array substrate. This may prevent position errors, enhance display quality, produce a wider viewing angle, and lower color shift sometimes associated with conventional liquid crystal display devices and methods.

  • Publication number: 20090180063
    Abstract: A display has color pixels that can be controlled to show color images. Differences in electric fields in different color pixels having color filters with different dielectric constants can be compensated by providing electrodes with different patterns for the different color pixels. For example, the electrodes can have slits in which the widths of the slits can be different for pixels having different colors.
