  • 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.
