Patent ID: 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. Therefore, brightness uniformity of the panel can be improved. A method for manufacturing the panel is further disclosed. A performance of the panel can be ensured, and a product quality can be improved.
