  • Patent number: 10658441
    Abstract: A display may have an array of pixels formed from organic light-emitting diodes and thin-film transistor circuitry. Each pixel may include organic layers interposed between an anode and a cathode. The organic layers may emit out-coupled light that escapes the display and waveguided light that is waveguided within the organic layers. A reflector may be placed at the edge of the organic layers to reflect the waveguided light out of the display. The reflector may be located within a pixel definition layer and may be formed from metal or may be formed from one or more interfaces between high-refractive-index material and low-refractive-index material. The reflector may be formed from an extended portion of the pixel anode. The reflector may be formed from light-reflecting particles that are suspended in the pixel definition layer.

  • Patent number: 7568828
    Abstract: A light guide plate includes a light incidence surface, a light reflection surface, and a light emission surface. The light reflection surface forms a plurality of light-guiding structures extending in a direction substantially parallel to a light source. The light reflection surface has an edge margin section adjacent to the light incidence surface and having opposite end zones each containing auxiliary light-guiding structures that extend in a direction substantially perpendicular to the light source and has an irregular V-shaped cross-section defined by a long inclined side, which faces endwise, and a short inclined side. The auxiliary light-guiding structures are distributed from a densest condition at each end portion toward a sparsest condition at a middle portion of the edge margin section. The long side helps to redirect a greater amount of light to a desired light emission direction thereby enhancing uniformity of light emission of the light guide plate.

  • Publication number: 20090129120
    Abstract: A light guide plate includes a light incidence surface, a light reflection surface, and a light emission surface. The light emission surface forms a plurality of light-guiding structures, which are extended in a direction substantially perpendicular to a lengthwise direction of a light source. The light-guiding structures have a substantially V-shaped cross-section and, among the light-guiding structures, those arranged in opposite endwise zones of the light emission surface in the lengthwise direction have an irregular V-shaped cross-section defined by a long inclined side, which faces endwise, and a short inclined side. The long and short sides respectively form first and second inclined angles with respect to the light emission surface and the first included angle is smaller than the second included angle and the first inclined angle gets smaller with the associated light-guiding structure located closer to the lengthwise end.
