  • Patent number: 8305338
    Abstract: A liquid crystal display apparatus and backlight adjustment method are provided. Backlight luminance sensors 111A to 111D are disposed in the vicinity of four outer corners of an effective screen of an LCD panel 121. Each of the backlight luminance sensors 111A to 111D detects the luminance of each of three primary colors. A backlight unit is composed of a three-primary LED array and a light diffusion unit. Transistors of the backlight luminance sensors and transistors of a pixel portion are formed on the same substrate in the same process. When a transistor is irradiated with backlight in its sufficient off region, an off current occurs due to light excitation. Since the value of the off current corresponds to the luminance of the rays of backlight that irradiates the transistor, the luminance of the backlight is detected with an output voltage into which the off current is converted. As a result, the luminance of the backlight is kept constant.

  • Patent number: 8289301
    Abstract: Methods and systems are disclosed for presenting media content on display systems. The display system includes two or more displays. In some display systems, the displays may be oriented in at least two different directions. Each of the displays are connected to a graphics communication bus. The graphics communication bus communicates common content information for the displays and discrete radiance-control information, which may contain different intensity and color control information for each of the displays. Each of the displays present the content information and adjust radiance characteristics of its display in response to the discrete radiance-control information associated with that display. The display system may include a computing system for controlling the graphics communication bus. The display system may also include ambient light sensors on each facet of the multifaceted display. Information from the ambient light sensors may be used for determining the discrete radiance-control information.
