  • Patent number: 11165048
    Abstract: A display panel, a method of manufacturing the same and a display device are provided. Nano-array structures are produced on a surface of a black color resist unit of a color filter layer, so that a reflectance of the color filter layer is reduced because light is absorbed and diffuse-reflected through the nano-array structures, thereby increasing the contrast of the display panel.

  • Publication number: 20210335952
    Abstract: An organic light-emitting display panel includes a thin-film transistor layer, a light-emitting function layer, and a thin-film encapsulation layer which overlap sequentially, and a shading layer, a color film layer, and an anti-reflection layer. The shading layer is disposed on the thin-film encapsulation layer. The color film layer is disposed on the thin-film encapsulation layer. The color film layer includes a first color film layer, a second color film layer, and a third color film layer disposed at an interval from each other. The shading layer is disposed at intervals among the first color film layer, the second color film layer, and the third color film layer. The anti-reflection layer is disposed on at least one surface of the shading layer and the color film layer.

  • Publication number: 20210151508
    Abstract: An organic light-emitting diode (OLED) panel and a manufacturing method thereof are provided, wherein a color filter layer of the OLED panel includes a first color filter layer, a second color filter layer, a third color filter layer, and a reflective layer disposed between the first color filter layer, the second color filter layer, and the third color filter layer, wherein material of the reflective layer is same as material of the first color filter layer. Because the first color filter layer and the reflective layer are the same material, consumable cost of the mask is saved.

  • Patent number: 11005080
    Abstract: The present invention provides an OLED display screen and a manufacturing method thereof. The OLED display screen includes a substrate, a functional layer, and a polarizing layer including a photoresist layer. A concave-convex structure is disposed on a surface of the polarizing layer facing away from the functional layer. The manufacturing method of the OLED display screen includes the steps: forming a display panel and forming a polarizing layer. The invention adopts the polarizing layer instead of a polarizer, and designs the concave-convex structure on the surface of the polarizing layer, thereby reducing reflectance of the surface of the polarizing layer and improving light emitting rate of the light emitting layer. Moreover, the concave-convex structure can change light angles and increase viewing angles, thereby improving narrow viewing angles of current OLED display screens and issues affecting readability, and improving readability of OLED display screens under outdoor sunlight.
