  • Patent number: 11127341
    Abstract: A light emitting module including a circuit carrier and a plurality of light emitting devices is provided. The circuit carrier includes a first circuit layer, a second circuit layer, a dielectric layer and a plurality of conductive vias. The first circuit layer and the second circuit layer are located at two opposite sides of the dielectric layer. The conductive vias pass through the dielectric layer and two opposite end portions of each of the conductive vias are respectively connected to the first circuit layer and the second circuit layer. The light emitting devices are electrically bonded to the first circuit layer. Moreover, the light emitting devices are disposed in a device disposing area of the circuit carrier and the conductive vias are arranged outside the device disposing area. A display device is also provided.

  • Patent number: 10727380
    Abstract: A method for manufacturing a wavelength converting film is provided. A release film is provided. At a least one coating process is performed to form at least one wavelength converting layer on the release film, wherein a first contact surface of the at least one wavelength converting layer and the release film has a first roughness. An adhesive layer is formed on a surface of the wavelength converting layer farthest from the release film, wherein a second contact surface of the adhesive layer and the wavelength converting layer has a second roughness. The second roughness is greater than the first roughness.

  • Patent number: 9705051
    Abstract: A light emitting device includes an epitaxial structure and a sheet-shaped wavelength converting layer. The sheet-shaped wavelength converting layer is disposed on the epitaxial structure and at least includes a first wavelength converting unit layer and a second wavelength converting unit layer. The first wavelength converting unit layer is disposed between the second wavelength converting unit layer and the epitaxial structure. An emission peak wavelength of the first wavelength converting unit layer is greater than an emission peak wavelength of the second wavelength converting unit layer. A full width half magnitude of the second wavelength converting unit layer is greater than a full width half magnitude of the first wavelength converting unit layer.
