    Abstract: The present invention teaches a white balance method and device for a LCD panel. The method includes the following steps. Step S1 provides a LCD panel, including a mask-joint area and a non-mask-joint area outside the mask-joint area. The mask-joint area includes multiple first color resists arranged in an array, and the non-mask-joint area includes multiple second color resists arranged in an array. The first and second color resists are of different dimensions. Step S2 obtains a first white balance driving table for the mask-joint area and a second white balance driving table for the non-mask-joint area. Step S3 conducts white balance to the mask-joint area and non-mask-joint area using the first and second white balance driving tables, respectively. By applying different white balance driving tables to the mask-joint area and the non-mask-joint area, the white balance effect is improved, and the display quality of the LCD panel is enhanced.

  • Patent number: 8767137
    Abstract: In a liquid crystal display device, the reduction of power consumption is realized by reddening a backlight while maintaining a white balance. An aperture ratio of a red subpixel and an aperture ratio of a blue subpixel are set such that, in a state where an aperture ratio of a green subpixel in each pixel of a liquid crystal panel is fixed to a desired value, white brightness efficiency takes a maximum value which is set based on a balance between light emission efficiency which is increased corresponding to lowering of a color temperature of the backlight and transmissivity of the pixel which is decreased corresponding to the increase of the aperture ratio of the blue subpixel.

  • Patent number: 8749737
    Abstract: Techniques are provided for controlling the colors of reflected light out of a display surface in a display device, such that display discoloration (e.g., green tinting) may be reduced, particularly when the display is operating in bright ambient environments. In one embodiment, a display device may include a color filter black mask layer having an arrangement of red, green, and blue color filter areas, where the red and/or blue color filter areas are substantially greater than the green color filter area. In some embodiments, the display device may include red and blue color filter pigment resin areas which may be disposed over the reflective areas to increase the overall amount of red and blue light that will be generated by reflected light to result in a total light reflection that is substantially neutral in color.

    Abstract: An optical film for reducing color shift and an LCD having the same. The optical film is disposed in front of a display panel of the LCD. The optical film includes a background layer and a plurality of engraved or embossed lens sections formed in the background layer such that they are spaced apart from each other. When light having different colors depending on a viewing angle and a grayscale level is emitted, a portion of the light incident onto the lens sections is diffused, and is thus mixed with another portion of the light passing between adjacent lens sections. The cross-section of the lens sections includes first, second and third sides. The first and second sides face each other and are connected by the third side. The average curvature of the third side is smaller than that of the first side and than that of the second side.
