Embodiment Construction

[0021] The present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the present invention, but not to limit the present invention. In addition, it should be noted that, for the convenience of description, only some structures related to the present invention are shown in the drawings but not all structures.

[0022] figure 1 It is a structural schematic diagram of a retaining wall of a display panel in the prior art, refer to figure 1 , in the non-display area, there is an intermediate layer 4 , an inorganic encapsulation layer 2 and a barrier wall 1 on the substrate 5 . The intermediate layer 4 includes a signal line layer and an insulating layer, etc., and the barrier wall 1 is used to support the mask plate 3 forming the inorganic packaging layer 2 (it will be removed after its function is completed). In the prior...

Abstract

The invention discloses an organic light-emitting display panel and a display apparatus. The organic light-emitting display panel comprises a display area and a non-display area, wherein the display area comprises a substrate, a driving circuit layer and an light-emitting device layer disposed on the driving circuit layer; and the non-display area comprises a retaining wall arranged to encircle the display area, the retaining wall comprises at least one support layer, a barrier layer disposed on the support layer and multiple projections formed on the barrier layer, and the multiple projections are successively arranged along a direction away from the display area. The organic light-emitting display panel further comprises a packaging layer which covers the display area and the surfaces of a part of the projections. According to the invention, through designing the multiple projections at the top end of the retaining wall, the edge of the packaging layer can be sealed only by use of one retaining wall, the frame width of the display panel is reduced, the multiple projections generate deformation to make up for slits when being extruded by a mask, through the multiple projections, diffusion paths of reaction gas during deposition are also increased, diffusion can be ended in the multiple projections, and a shadow effect is eliminated.

Description

technical field [0001] Embodiments of the present invention relate to the field of display technology, and in particular, to an organic light-emitting display panel and a display device. Background technique [0002] In the manufacturing process of the organic light-emitting display panel, a mask plate is used to deposit an inorganic film in the display area to form a thin-film encapsulation layer structure to prevent water vapor from corroding the organic light-emitting material. [0003] In order to ensure that the mask plate does not damage the display device and the wiring, a retaining wall (Bank or Dam) is used to support the edge of the mask plate, and the retaining wall has a certain height. In the prior art, in order to ensure the encapsulation effect of the inorganic encapsulation layer at the edge, a plurality of retaining walls are used to form the boundary, and gaps are left between the retaining walls to increase the width of the frame. [0004] Therefore, how ...
