  • Patent number: 12249292
    Abstract: A display device and a projector are provided. The display device includes a pixel light-emitting panel and multiple color conversion panels. The pixel light-emitting panel includes an N1 number of light-emitting pixel units distributed in an array, and the light-emitting pixel units are driven to emit light through a driver. A first color conversion panel includes an N2 number of first color pixels and an N3 number of first transparent pixels. The first color pixels and the first transparent pixels are disposed relative to the light-emitting pixel units. A second color conversion panel includes an N4 number of second color pixels and an N5 number of second transparent pixels. The second color pixels and the second transparent pixels are disposed relative to the light-emitting pixel units. The lights generated by at least part of the light-emitting pixel units sequentially pass through the first color pixels and the second transparent pixels to achieve the color conversion.

  • Publication number: 20240145641
    Abstract: A color conversion panel and a display device are provided. The color conversion panel includes an opaque substrate and a sapphire substrate. The opaque substrate includes a plurality of first pixel openings, a plurality of second pixel openings and a plurality of third pixel openings. The first pixel openings are filled with red quantum dot material, and the second pixel openings are filled with green quantum dot material. The sapphire substrate is on the opaque substrate. A first surface of the sapphire substrate that faces the opaque substrate has a plurality of first arc surfaces corresponding to the first pixel openings, a plurality of second arc surfaces corresponding to the second pixel openings, and a plurality of third arc surfaces corresponding to the third pixel openings.

  • Patent number: 9112101
    Abstract: A method for manufacturing a light-emitting device, comprises steps of: providing an as-cut wafer having an irregularly uneven surface comprising surface roughness greater than 0.5 ?m; and forming a light-emitting stack on the irregularly uneven surface of the as-cut wafer by an epitaxial growth method, and the light-emitting stack comprises an upper surface having surface roughness less than 0.2 nm; wherein there is no patterning or roughing process after the step of providing the as-cut wafer and before the step of forming the light-emitting stack on the irregularly uneven surface of the as-cut wafer.
