Rotatable Disc Record Receiver Patents (Class 346/102)
  • Patent number: 10477645
    Abstract: A display apparatus and an operating method of the display apparatus are provided. The display apparatus includes a display panel, a light luminance sensing circuit, a controller, and a driving circuit. The light luminance sensing circuit senses luminance intensity to generate an output sensing signal. The controller receives the output sensing signal and converts the output sensing signal to generate selecting numeric information according to look-up information. The controller generates a control driving signal according to the selecting numeric information. The look-up information records a corresponding relation between a plurality of electric characteristic values and a plurality of pieces of numeric information. The driving circuit adjusts the luminance intensity of a lighting element according to the control driving signal.

  • Publication number: 20040095402
    Abstract: The present invention provides a liquid crystal display capable of detecting external light by an optical sensor without providing a window in front of a product. A top face of a liquid crystal display panel (18) corresponds to a display surface. A light-guiding plate (19) is disposed on a rear face of the liquid crystal display panel (18). A backlight (9) shown in FIG. 1 is attached to the light-guiding plate (19). Light emitted from the backlight (9) is guided to the display surface of the liquid crystal display panel (18) by the light-guiding plate (19). A reflection sheet (20) is disposed on a bottom face of the light-guiding plate (19). An optical sensor (10) is attached to a side face of the light-guiding plate (19) with its light-receiving face facing the inside of the light-guiding plate (19).
