  • Patent number: 11435792
    Abstract: A display panel and a display device are provided. The display panel has a display area and a fan-out area. The fan-out area and the display area at least partially overlap. By arranging at least one part of the fan-out area in the display area, the display area of the display panel expends to the fan-out area, and therefore the area of the display area of the display panel is increased to reduce the area of the non-display area occupied by the fan-out area. That is, the problem that the non-display area of the display panel is too large is alleviated and the narrow border and full screen technology are further implemented.

  • Patent number: 10804343
    Abstract: An AMOLED panel is disclosed. The panel includes, from bottom up in sequence, a substrate, a first electrode layer, an opaque insulation layer, and pixel defined layers among which pixel regions are arranged. The opaque insulation layer extends to the pixel region in which an organic light emitting layer is arranged. The organic light emitting layer has a film thickness non-uniform region at a position near to an inclined surface of a pixel defined layer facing the pixel region. When observed along a normal line direction of the substrate, a projection of the film thickness non-uniform region on the opaque insulation layer is inside the opaque insulation layer. In the panel, the non-uniform light resulted by the film thickness non-uniform region can be completely shaded by the opaque insulation layer. In this manner, only light with a uniform brightness that is emitted by a film thickness uniform region can transmit through the substrate, and thus the pixel region can have a uniform brightness.

  • Patent number: 10790458
    Abstract: A flexible AMOLED substrate and a manufacturing method thereof are provided. The method includes: forming a flexible backing, which includes a display section and a bending section disposed on an outer circumference of the display section; forming a buffer layer on the flexible backing, removing a portion of the buffer layer that is disposed on the bending section and preserving a portion of the buffer layer that is disposed on the display section so that an inorganic insulation layer on the bending section has a reduced thickness to improve bending resistance of the bending section of the flexible AMOLED substrate and thus improving production yield. The flexible AMOLED substrate is manufactured with the above method, in which an inorganic insulation layer included in a bending section has a reduced thickness so that the bending section of the flexible AMOLED substrate shows better resistance against bending and provides high production yield.
