  • Patent number: 11196983
    Abstract: An imaging system includes a light source that, in operation, emits an emitted light containing a near-infrared light in a first wavelength region, an image sensor, and a double-band pass filter that transmits a visible light in at least a part of a wavelength region out of a visible region and the near-infrared light in the first wavelength region. The image sensor includes light detection cells, a first filter that selectively transmits the near-infrared light in the first wavelength region, second to fourth filters that selectively transmit lights in second to fourth wavelength regions, respectively, which are contained in the visible light, and an infrared absorption filter. The infrared absorption filter faces the second to fourth filters and absorbs the near-infrared light in the first wavelength region.

  • Patent number: 11067739
    Abstract: Provided are an edge-lit surface light source device and a liquid crystal display device, both of which are capable of two-dimensional local dimming without image contrast being reduced due to stray light. Even when light from LEDs that should be extracted by means of a light extraction pattern provided in a first section of a light guide plate is passed through the first section without being extracted, the light repeatedly strikes on a light absorbing layer formed in a second section, whereby much of the light is absorbed in the second section. Accordingly, little light from the LEDs is extracted from a third section, from which light from LEDs should originally be extracted, with the result that image contrast can be prevented from being reduced due to stray light.
