The second panel is an LCD panel without color filters and is configured to increase contrast by decreasing black levels of dark portions of images (making them blacker or darker) using polarization rotation and filtration. Preferably, the second LCD panel is of higher resolution than the first LCD panel. The panels may be directly illuminated or edge lit, and may be globally or locally dimmed monochrome or multi primary lights that may also include individual control of color intensities for each image or frame displayed. The panels may be placed in any order, but preferably are arranged such that active layers in each panel are as close together as possible. Brightness is maintained by the combination of reusing polarization between the panels and by not going through more than one set of color filters.

  • Patent number: 9829736
    Abstract: Provided is a display device comprising a liquid-crystal panel and an optical sheet member including multiple stacked optical sheets emitting light from a light source toward the liquid-crystal panel, which can alleviate unevenness in light even in the case where, for example, light with such unevenness is emitted from the optical sheet member due to warps or wrinkles generated in the optical sheet member caused by heat generated by the light source. A diffusion sheet is provided between a liquid-crystal panel and an optical sheet member with a gap from the optical sheet member. The light emitted through the optical sheet member is diffused by the diffusion sheet and gap, and then enters the liquid-crystal panel.

  • Patent number: 9784428
    Abstract: Various embodiments relate to a lighting device with an optoelectronic light source, an optical body downstream thereof for distributing the light, and a diffuser downstream of the latter, onto the light entry surface of which the light emitted by the optical body falls and the light exit surface of which represents a light emission surface of the lighting device. To homogenize the luminous intensity on the light exit surface, in addition to distributing the light with the optical body, the diffuser is not provided to be uniformly scattering to such an extent that light falling thereon in a central region is scattered more intensely than light falling thereon in an edge region.

  • Patent number: 9733415
    Abstract: In an embodiment, a display panel unit includes a reflective polarizing layer, a transparent layer, and a display panel. The polarizing layer transmits a first polarized component of light incident on an incident surface to an exit surface and reflects a second polarized component of the light. The transparent layer transmits the first and second polarized component of the light incident on a second surface to a first surface adhered to the incident surface and transmits the second polarized component reflected by the polarizing layer to be incident on the first surface to the second surface. The panel faces the exit surface, and selectively transmits the light exiting from the exit surface.

  • Patent number: 9678263
    Abstract: The embodiments of the invention disclose a scanning type backlight module and a display device. Since a laser light source with good collimation is applied, during a display time of a frame, with the modulation of the optical path regulator, the laser emitted from the laser light source performs a progressive scanning for a region corresponding to at least one row of pixel units in a light guide plate or a display panel. Therefore, the problem of dynamic picture ghosting can be solved effectively; moreover, since the progressive scanning for the entire light guide plate can be realized by changing the light propagation path of the laser emitted from the laser light source with the optical path regulator, the number of the laser light sources can be reduced and the production cost can be decreased.
