  • Publication number: 20230343894
    Abstract: A pixel package includes a carrier, a first light-emitting unit, a second light emitting unit, a reflective layer, and a light-absorbing layer. The carrier has a top surface and a conductive layer. The first light-emitting unit and the second light-emitting unit are arranged on the conductive layer and have a light-emitting surface and a side surface respectively. The reflective layer is arranged on the top surface and contacts the conductive layer. The light-absorbing layer is arranged on the reflective layer and contacts the first side surface and the second side surface while exposing the first light-emitting surface and the second light-emitting surface. In a cross-sectional view, the light-absorbing layer has a first thickness and a second thickness between the first side surface and the second side surface. The first thickness is farther away from and the first side surface than the second thickness, and is smaller than the second thickness.

  • Publication number: 20120097985
    Abstract: A light emitting diode (LED) package includes a substrate, a light emitting diode (LED) die mounted to the substrate, a frame on the substrate, a wire bonded to the light emitting diode (LED) die and to the substrate, and a transparent dome configured as a lens encapsulating the light emitting diode (LED) die. A method for fabricating a light emitting diode (LED) package includes the steps of: providing a substrate; forming a frame on the substrate; attaching a light emitting diode (LED) die to the substrate; wire bonding a wire to the light emitting diode (LED) die and to the substrate; and dispensing a transparent encapsulation material on the frame configured to form a transparent dome and lens for encapsulating the light emitting diode (LED) die.

  • Publication number: 20090321758
    Abstract: Light-emitting semiconductor devices are provided with certain layers in an effort to produce increased luminous intensity when compared to conventional light-emitting devices. The light-emitting semiconductor device includes a light-emitting semiconductor; a first transparent layer disposed over the light-emitting semiconductor; a first wavelength-converting layer disposed over the first transparent layer, wherein an upper surface of the wavelength-converting layer is curved; and a second transparent layer disposed over the wavelength-converting layer, wherein an upper surface of the second transparent layer is curved or tapered.
