  • Patent number: 12189234
    Abstract: A multilayer light diffuser plate and a method for manufacturing the same are disclosed. The multilayer light diffusion plate comprises a main layer and a partially-transmissive and partially-reflective layer located under the main layer. The top surface of the main layer is the light-emitting surface, and the light-incident surface is the bottom surface of the partially-transmissive and partially-reflective layer. The partially-transmissive and partially-reflective layer comprises a plurality of first base material layers and a plurality of second base material layers stacked alternately. The materials of the first and second base material layers have different refractive indices. The partially-transmissive and partially-reflective layer formed by alternately stacking the first and second base material layers with different refractive indices is arranged on the light-incident surface of the light diffuser plate by means of extrusion, which is simpler and less expensive to manufacture.

  • Publication number: 20240392947
    Abstract: A light diffusion plate is configured to be assembled with a blue light source module having blue Mini LEDs to form a white light backlight module. The light diffusion plate is added with organic dyes with light-emission wavelength of 490-650 nm in order to convert the blue light into white light. The light diffusion plate is made by a foaming extrusion process and contains a plurality of micro-bubbles with a size of 60-400 ?m and a weight-reduction ratio of 15-25% for improving the uniformity of white light and resolving the MURA problem. The size of micro-bubbles is controlled by reducing the temperature of at the exit end of the T-die head, such that the wavelength of the white light emitted from the light diffusion plate can be narrower to achieve the effect of wider color gamut display.

  • Publication number: 20240361621
    Abstract: The invention refers to a quantum dot light diffuser plate that can be assembled on a backlight module with blue LEDs as the bottom light source. Microstructures having concave portions and convex portions are formed on the surface of the diffuser plate. A quantum dot layer comprising green quantum dots and red quantum dots is applied only on the concave portions of the microstructures, and thus is separated by the convex portions into small parts independent of each other. A water-blocking and gas-blocking layer is arranged on the upper surface of the quantum dot layer. The water vapor and oxygen from the outside cannot penetrate the side end faces of the quantum dot layer and invade the entire quantum dot layer, such that, the diffuser plate of the invention can have the advantages of simple process, low cost and high production yield.

  • Patent number: 12085805
    Abstract: The invention discloses a diffusion plate for use in a backlight module with a low optical path distance (OD), which can be assembled on a backlight module with a plurality of light-emitting diodes (LEDs) as the light source below. Different diffusion particle additives are added to the surface layers and the main layer of the diffusion plate, and then extrude it with foaming extrusion technology. By making different combinations of the refractive index and the amount of the original resin materials, microbubbles, and diffusion particle additives of the surface layers and the main layer, the light refractive index of the upper and lower surface layers is substantially greater than which of the main layer. Such that, the light emitted by the light source below can be diffused more effectively, and thereby achieving a better shading effect of MURA, so as to produce a uniform surface light source.
