  • Publication number: 20210184159
    Abstract: Provided herein are a flexible organic light-emitting display (OLED) and a spring component. The film layers are pulled one on one by spring components to make the film layers flat when being unfolded and free of irreversible deformation when being folded. A lubricating layer is disposed between adjacent film layers so that the action force between the adjacent film layers is reduced, thereby making the flexible organic light-emitting display (OLED) flat and free of creases when being unfolded.

  • Publication number: 20210005695
    Abstract: A flexible organic light-emitting diode (OLED) display substrate and manufacturing method using the same are provided. The flexible OLED display substrate includes a display region, a non-display region, and a bending region connected to the display region and the non-display region. The bending region is provided with multiple liquid conductive wires spaced from each other. Each liquid conductive wire includes a conductive flow channel disposed in the bending region and a pair of metal wire portions connected to two ends of the conductive flow channel A packaging layer is arranged on each conductive flow channel to store a liquid conductive material. The liquid conductive material is sealed in each conductive flow channel. Therefore, the liquid conductive wires can greatly improve the production yield of the bending region, and overcome a problem that a conventional bending region is prone to break during a bending process.

  • Patent number: 10777755
    Abstract: A compound adhesive structure for bonding film layers of a display panel is disclosed. The compound adhesive structure includes an optical adhesive body; multiple flexible enhancement bodies which is disposed on a surface of the optical adhesive body and/or inside the optical adhesive body, wherein each of the flexible enhancement bodies includes a large end and a small end which is gradually narrowing in cross section from the large end; wherein a refractive index of each of the flexible enhancement bodies is similar to a refractive index of the optical adhesive body, and a density of each of the flexible enhancement bodies is similar to a density of the optical adhesive body. The present invention can suppress and break a viscosity flowing of the optical adhesive in the bending and deformation process of the display panel, and improve a wrinkle phenomenon in the bending process of the display panel.
