    摘要： A BLU includes a 2D array of LEDs producing light with an angular distribution of nominally ±90 degrees around a center. A transparent solid material layer is positioned with a bottom surface over the 2D array of LEDs and configured to transform the light produced by the 2D array into light having an angular distribution of nominally less than ±90 degrees around the at a top surface of the transparent solid material layer. A diffuser film is positioned over the top surface of the transparent solid material layer configured to provide a FWHM of greater than 60 degrees and configured to diffuse the light produced at the top surface of the transparent solid material layer to produce diffused light at a top surface of the diffuser film. A BEF positioned over the top surface of the diffuser film and comprising a plurality of prism microstructures, where at least some prism microstructures have an apex angle of approximately ninety degrees. The BEF configured to narrow an angular optical distribution of the diffused light produced at the top surface of the diffuser film, thereby providing uniform and high brightness light output from the back light unit.

    摘要： A display panel and a display apparatus. The display panel includes an array substrate and a color filter substrate opposite to each other, the array substrate being provided with a plurality of pixel regions arranged in an array, and the pixel regions closest to corners of the array substrate being first-type pixel regions, where the color filter substrate includes: a base substrate; a sealant between the base substrate and the array substrate; and a color filter layer on the base substrate and including a plurality of filter units, where the filter units includes first filter units corresponding to the first-type pixel regions, a portion of an orthographic projection of the first filter unit onto the base substrate facing a corner of the base substrate has a non-right-angle contour, and orthographic projections of the first filter unit and the sealant onto the base substrate do not overlap with each other.

    摘要： A display and window assembly includes a bezel that defines a first window aperture, a second window aperture, and a display aperture located between the first and second window apertures. A display unit is aligned with the display aperture, a first window is aligned with the first window aperture, and a second window is aligned with the second window aperture. The first window and the second window each include a front substrate that has a first surface and a second surface opposite the first surface. A second substrate has a third surface and a fourth surface opposite the third surface. The second and third surfaces face each other to define a gap. A first electrode is coupled to the second surface, and a second electrode is coupled to the third surface. An electro-optic medium is located between the first electrode and the second electrode.

    摘要： A light control sheet includes an adhesive layer attached to a transparent material, and a light control layer attached to the transparent material via the adhesive layer, the light control layer having a transparent state or an opaque state depending on a voltage is applied to the light control layer. At least one of the adhesive layer and the light control layer includes a filter absorbing part of light in the visible region. Transmittance is 10% or less for light with a wavelength range of 420 nm or less passing through the light control window from the light control sheet toward the transparent material in a first direction, and light from a standard light source D65 passing through the light control window from the transparent material toward the light control sheet in a second direction has a yellowness index YI of 10 or less according to JIS K 7373: 2006.
