  • Patent number: 9857521
    Abstract: A display may have an array of pixels that display images for a user. The backlight unit may have a light-guide layer. An array of light-emitting diodes may emit light into an edge of the light-guide layer. The light guide layer may overlap a backlight reflector. The backlight reflector may include a backlight reflector panel formed from a stack of dielectric layers on a rectangular substrate. The backlight reflector may also include a strip of backlight reflector tape having an edge that is overlapped by an edge portion of the backlight reflector panel. Color compensating features such as printed colored ink patterns may be formed on the backlight reflector to adjust the color of backlight illumination in portions of the backlight unit adjacent to the light-emitting diodes.

  • Patent number: 9535206
    Abstract: Display backlight structures may provide backlight illumination that passes through display layers in the display. Light-emitting diodes may emit blue light into an edge of a light guide plate. Optical films may overlap the light guide plate. The optical films may include a quantum dot enhancement film. A peripheral strip of yellow reflector or other light control structures may be incorporated into the backlight structures to reduce blue edge effects. The light control structures may have features with a spatially varying density, may be formed from quantum dot enhancement film, or may be formed form other structures. The light control structures may be formed on the surfaces of the optical films, on a reflective layer under the light guide plate, or on a surface of a mold frame or other structure that lies in a plane parallel to the plane of the light guide plate.

  • Publication number: 20080204823
    Abstract: A compensating method for image scanning measures original optical values corresponding to a plurality of scan lines in a frame using a plurality of channels. First, a reference channel is selected from the plurality of channels. Based on the differences between the actual exposure locations of the reference channel and other channels on the frame, corresponding weighting values are then generated for compensating the original optical values measured by other channels, thereby generating the correction optical values for other channels.
