  • Publication number: 20130241810
    Abstract: An image processing apparatus includes an image display unit and a luminance control unit. The image display unit includes pixels arranged in a matrix, each of which is formed of a first sub-pixel, a second sub-pixel, a third sub-pixel, and a fourth sub-pixel, and performs image display. The luminance control unit adjusts a ratio between a generation amount of first luminance generated by the first sub-pixel, the second sub-pixel, and the third sub-pixel and a generation amount of second luminance generated by the fourth sub-pixel. Over all input tones, the luminance control unit makes the generation amount of the second luminance lower than the generation amount of the first luminance and generates the second luminance so that a function representing a luminance value of the second luminance is continuous.

    Abstract: In a normally black mode liquid crystal display, the liquid crystal display and the method prevents the light leakage arising from existing the step for adjusting the thickness of the liquid crystal layer between the reflective electrode and the transparent electrode and that high contrast displaying can be possible. The interval adjustment layer is formed between the first substrate that the reflective electrode is formed in the reflective region and the transparent electrode is formed in the transmissive region, and the second substrate that is fixed at predetermined interval from the first substrate. This interval adjustment layer is adjuster of the thickness of the liquid crystal layer in the reflective region on the second substrate, and the thickness of the liquid crystal layer in the reflective region is preferable to be set approximately the thickness of the liquid crystal layer of the transmissive region.
