  • Publication number: 20240101433
    Abstract: The present disclosure discloses a method for preparing a hierarchical porous material for a molecular sieve with an MFI structure. In the present disclosure, porous silicon dioxide is used as a carrier on a surface of which a nano zeolite seed is loaded, and then subjected to treatment with a secondary growth compound fluid and hydrothermal crystallization, so that a nano zeolite molecular sieve membrane is further grown on the surface of the porous silicon dioxide. The specific surface area and pore volume of the hierarchical porous material for the molecular sieve with the MFI structure prepared by the present disclosure are greatly improved compared with those of the original porous silicon dioxide. The material not only has the macroporous structure of the porous silicon dioxide, but also incorporates micropores of the molecular sieve itself and mesopores formed by molecular sieve agglomeration.

  • Patent number: 11579481
    Abstract: A display panel and a display device are provided. The display panel includes a display component layer and a first anti-reflective film arranged on the display component layer. The display component layer includes a first polarizer, a first substrate arranged on the first polarizer, a second substrate arranged on the first substrate and a second polarizer arranged on the second substrate. The anti-reflective film on the second polarizer may reduce reflected light energy while increasing transmitted light energy.

  • Publication number: 20220252936
    Abstract: A display panel, a display module, and a display device are provided. The display panel includes a total reflection display unit and a frame enclosing the reflective display unit. The frame includes a light-shielding portion and a reflective layer. The light-shielding portion has a first surface parallel to a first direction and a second surface oppositely located to the first surface. The reflective layer covers the first surface or the second surface. The reflective layer can reflect the light irradiated on the surface of the light shielding portion or entering the light shielding portion back to the total reflection display unit again, avoiding the waste caused by the scattered light caused by the propagation path of the light, thereby improving the utilization rate of light.

  • Patent number: 11385395
    Abstract: The present application discloses a light guide plate and a display device. The light guide plate has a light emitting surface configured to guide light out, the light emitting surface is provided with first micro structures, and the first micro structures protrude from the light emitting surface; the first micro structures are gradually tightly arranged on the light emitting surface inwards from the light incident surface; widths of the first micro structures gradually reduce inwards from the light incident surface. Light passes through the first micro structures protruding from the light emitting surface, an incident angle is reduced, so that the light is not prone to generate total reflection, a penetration rate of the light on the light emitting surface of the light guide plate is improved, and a light utility rate is increased.

  • Patent number: 11360344
    Abstract: The present disclosure provides a liquid crystal display panel and a liquid crystal display device, including a first substrate; a second substrate; a liquid crystal layer, disposed between the first substrate and the second substrate; a reflective layer, disposed on a side of the first substrate facing the liquid crystal layer; and a color filter layer, disposed on the first substrate and covering the reflective layer. When light passes through the second substrate reaching the color filter layer, the reflective layer is configured to reflect the light, which is filtered by the color filter layer, to the second substrate. The liquid crystal display panel and the liquid crystal display device emit light without a light source, having a reduced loss rate of the light, an increased light utilization rate, and an increased light reflectivity.
