  • Publication number: 20240085739
    Abstract: A wavelength conversion element including a substrate, a blocking wall structure layer, and a wavelength conversion layer is provided. The blocking wall structure layer is disposed on a surface of the substrate and defines multiple microgrooves. Reflectivity of the blocking wall structure layer is in a range of 1% to 99%. The wavelength conversion layer is disposed in the microgrooves and includes multiple wavelength conversion particles. A height of the blocking wall structure layer along a normal direction of the surface of the substrate is greater than a height of the wavelength conversion layer along the normal direction of the surface of the substrate. A backlight module adopting the wavelength conversion element is also provided.

  • Publication number: 20220293042
    Abstract: A light source module, including a substrate, a plurality of light-emitting elements, and a quantum dot film is provided. The substrate has a bearing surface, and the plurality of light-emitting elements is disposed on the bearing surface. Each light-emitting element includes a first light-emitting chip and a second light-emitting chip. The first light-emitting chip is adapted to emit blue light. The second light-emitting chip is disposed beside the first light-emitting chip and is adapted to emit red light. The quantum dot film is disposed on the bearing surface, and adapted to convert blue light into green light. The plurality of light-emitting elements is located between the substrate and the quantum dot film. A display device of the invention is further provided.

  • Publication number: 20100026168
    Abstract: The present invention discloses a photo-curable hole-transport material used in a polymer light-emitting diode. The photo-curable hole-transport material comprises at least one first conjugate structure, at least one connecting structure, and at least one second conjugate structure. The first conjugate structure is a triarylamine derivative. The second conjugate structure is a carbazole derivative. The connecting structure is derived from one structure selected from the group consisting of the following or the combination thereof: urethane and urea structures.
