  • Publication number: 20190094590
    Abstract: The present invention aims to allow a liquid crystal display device with a built-in touch sensor using a common electrode as an electrode for touch detection to reduce occurrence of flicker when switching from the sleep period to the display period is performed. At least during a part of a sleep period, a display drive portion performs image data write processing in which a voltage is applied to a pixel electrode in a state in which a backlight is maintained in a light-out state by a backlight control portion. For example, the display drive portion applies a voltage corresponding to one of a specific image and a black image to a pixel electrode every predetermined period throughout the sleep period. Further, for example, the display drive portion applies a voltage corresponding to a display image during a period immediately before switching to the display period is performed in the sleep period.

  • Patent number: 8531368
    Abstract: In a transmissive liquid crystal display device including a liquid crystal panel and a backlight, the liquid crystal panel has pixels each divided into four subpixels, namely red (R), green (G), blue (B), and white (W) subpixels. Further, the backlight is a white backlight whose light emission luminance is controllable. Furthermore, a color-saturation conversion section performs a color-saturation reduction process on a first input RGB input signal serving as an original input signal, and then a gamma-correction section performs a gamma-correction process on the first RGB input signal. An output signal generation section calculates transmittances and a backlight value in accordance with gamma-corrected RGB input signal obtained after the gamma-correction process has been performed by the gamma-correction section.

The backlight is a white backlight by which luminance of emitted light is controllable. A color-saturation reducing section carries out a process of reducing color saturation on a first RGB input signal, which is an original input signal, so that the first RGB input signal becomes a second RGB input signal. Thereafter, an output signal generating section obtains a transmissivity and a backlight value on the basis of the second RGB input signal.

  • Patent number: 7944431
    Abstract: Each of image data sorted so as to correspond to divided areas respectively is stored in an in-area image memory. A maximum luminance extracting section extracts the maximum luminance value therefrom and records it onto the maximum luminance storage section. In accordance with the maximum luminance value that is thus stored in the maximum luminance storage section and that each of the areas has, a BL candidate value calculating section and a BL luminance difference adjusting section determine an emitted-light luminance in a target area such that a difference between the backlight luminance in the target area and the backlight luminance in its adjacent area is not more than a tolerance value.
