Embodiment 1

[0073] In this embodiment, as figure 1 As shown, the OLED display panel 100 has a non-display area, and the non-display area includes an encapsulation part encapsulated by the encapsulation layer and an edge part 1 that is not encapsulated by the encapsulation layer. The edge part 1 includes a flexible substrate 11, a buffer layer 14, Inorganic layer 12 and organic layer 13 .

[0074] The buffer layer 14 is provided on the upper surface of the upper flexible substrate 11 , the inorganic layer 12 is provided on the upper surface of the buffer layer 14 , and the inorganic layer 12 includes an inorganic layer body 123 , 5 dams 121 and 5 grooves 122 , 5 dams 121 and 5 grooves 122 are located at the edge of the inorganic layer 12, and the 5 dams 121 and the 5 grooves 122 are alternately arranged from outside to inside, and a groove 122, A dam portion 121 is formed between two adjacent groove portions 122 , and a groove portion 122 is defined between the innermost one of the five d...

Embodiment 2

[0080] like figure 2 As shown, the structure of this embodiment is substantially the same as that of the first embodiment, wherein the same components are given the same reference numerals, the difference is that the cross-sectional width of each stress groove 131 decreases linearly from top to bottom, and each stress groove 131 decreases linearly from top to bottom. The bottom surface of each stress slot 131 is a combination of two intersecting planes, so that the stress slot 131 is roughly formed as a V-shaped slot.

Embodiment 3

[0082] like image 3 As shown, the structure of this embodiment is substantially the same as that of the first embodiment, wherein the same components are given the same reference numerals, the difference is that the cross-sectional width of each stress groove 131 remains unchanged from top to bottom, and each The bottom surface of the stress groove 131 is flat.

Abstract

The invention discloses an OLED display panel and a display device having the same. The non-display area of ​​the OLED display panel includes an encapsulation part encapsulated by an encapsulation layer and an edge part not encapsulated by the encapsulation layer, and the edge part includes a flexible substrate, an inorganic layer and The organic layer, the inorganic layer is arranged on the flexible substrate, the edge of the inorganic layer has a plurality of dams and a plurality of grooves, the organic layer is arranged on the inorganic layer, and at least covers the plurality of dams and fills the plurality of grooves, the organic layer The surface on the side away from the inorganic layer is formed to be non-planar. The OLED display panel according to the present invention has reliable packaging and long service life.

Description

technical field [0001] The present invention relates to the field of display technology, in particular to an OLED display panel and a display device having the same. Background technique [0002] In the display industry, OLED display panels have the advantages of clear image quality, flexible products, and thinness. Due to the thin and light design of OLED display panels, there are higher requirements for the packaging effect of OLED display panels. However, in the related art, the edge of the OLED display panel is prone to cracks, especially when the edge of the OLED display panel collides, it is easy for water and oxygen to invade, causing the packaging failure of the OLED display panel and shortening the service life of the OLED display panel. SUMMARY OF THE INVENTION [0003] The present invention aims to solve at least one of the technical problems existing in the prior art. To this end, the present invention proposes an OLED display panel, the OLED display panel is ...
