  • Publication number: 20230221551
    Abstract: A light guide substrate, including a light coupling-in region with multiple first gratings, a light expansion region with multiple sub light expansion regions, and a light coupling-out region, is provided. Each sub light expansion region includes multiple second gratings. The sub light expansion regions include a first set of sub light expansion regions and a second set of sub light expansion regions. Each second grating in the first set of sub light expansion regions includes a first microstructure and a second microstructure. The light coupling-out region includes multiple third gratings. When an image light enters the light guide substrate from the light coupling-in region through the first gratings, the image light is first transmitted to the light expansion region in the light guide substrate, then transmitted to the light coupling-out region through the second gratings, and then emitted from the light coupling-out region through the third gratings.

  • Patent number: 10591770
    Abstract: A display device comprising a color filter layer and a light-emitting unit is provided. The color filter layer includes a first subpixel area, a second subpixel area and a third subpixel area. The first subpixel area includes a first quantum dot material, and the second subpixel area includes a second quantum dot material. The light-emitting unit provides light to the color filter layer. A wide color gamut and a polarization effect are achieved via the quantum dot materials and the polarization material. Furthermore, due to no additional loss of the light at the light-emitting unit (backlight module), the luminous efficiency is high.

  • Publication number: 20160146976
    Abstract: A substrate with moth eye structures and a method of manufacturing thereof are provided. The method includes: providing a substrate including a first surface and a second surface, and forming a plurality of moth eye structures on the first surface. Since the moth eye structures are integrally formed on the substrate, the moth eye structures and the substrate include the same hardness. The reflected light is offset through the graded refraction via the moth eye structures, and the transmittance of the substrate is improved.
