  • Publication number: 20230110159
    Abstract: A light emitting device includes a substrate, multiple light emitting diodes disposed on the substrate and a light-reflecting resist. The light emitting diode has a first electrode and a second electrode, both of which are disposed on a first surface of the light emitting diode facing the substrate. The light-reflecting resist is disposed between the light emitting diodes and directly contacts a side surface of the light emitting diode. At least a portion of the light-reflecting resist is disposed between the first electrode and the second electrode.

  • Patent number: 11137634
    Abstract: A display device includes a liquid crystal display module, a cover lens, and a polarizer structure. The liquid crystal display module has a display area and a non-display area connected to the display area. The liquid crystal display module includes a bezel, a backlight module, and a display panel. The display panel includes a first substrate, a lower polarizer, a second substrate, a liquid crystal layer, and a filter element. The polarizer structure is located between the cover lens and the second substrate. The polarizer structure includes a plurality of grids and a reflective layer. The grids cover the display area. The reflective layer surrounds the grids and covers a sidewall of the display panel and a sidewall of the bezel in a direction perpendicular to the cover lens. A manufacturing method of the polarizer structure is also provided.

  • Patent number: 11009743
    Abstract: A display panel has a display area and a peripheral area. The peripheral area is located outside the display area. The display panel includes a first substrate, a second substrate, and a display medium layer. The second substrate is located above the first substrate and includes a first polarization layer, a first quarter wave plate (QWP), a reflection layer, and a pixel array. The first polarization layer is located within the display area and the peripheral area and includes a wire-grid polarizer. The first QWP is located within the peripheral area. The reflection layer is located within the peripheral area, in which the first QWP is located between the first polarization layer and the reflection layer. The pixel array is at least located within the display area. The display medium layer is located between the first substrate and the second substrate.
