The central angle of the first anti-cracking groove body R1 is at most 210 degrees, the central angle is not required to be set to be too large, the strength of one side of the first electronic element area D1 departing from the first edge area SA1 is large, extra reinforcement is not required, and if the central angle is set to be too large, the aperture opening ratio of the organic light-emitting display panel is not favorably improved.
In some optional embodiments, please refer to fig. 5, and fig. 5 is a schematic diagram of another organic light emitting display panel structure provided in the embodiments of the present application. In this embodiment, the at least one electronic component region further includes a second electronic component region D2; the minimum distance B between the edge of the first electronic component area D1 and the edge of the second electronic component area D2 is less than or equal to 10mm; an area between the first electronic component area D1 and the second electronic component area D2 is an intermediate area M;

Optionally, the second anti-cracking groove body R2 is partially located in the middle area M. Since the first electronic component region D1 and the second electronic component region D2 are disposed more intensively and the minimum distance B between the edges is 10mm or less, the strength of the middle region M is also relatively weak. In this embodiment, the second anti-cracking groove R2 is extended into the middle area M, so that the strength of the middle area M can be further enhanced, and the reliability of the organic light-emitting display panel is improved.
Optionally, the second electronic element area D2 is circular, the second anti-cracking groove body R2 is arc-shaped, and the central angle a2 is 180 ° ± 30 °. The central angle of the second anti-cracking groove body R2 is at least 150 degrees, and the central angle is too small to provide effective protection for the second electronic element area D2. The central angle of second crack control cell body R2 is 210 at most, and the central angle needn't set up too big, and second electronic component district D2 is great at one side intensity that deviates from second marginal zone SA2, need not extra reinforcement, if too big with the central angle setting, is unfavorable for promoting organic light emitting display panel's aperture ratio.
An embodiment of the present application further provides a display device, as shown in fig. 9, fig. 9 is a schematic structural diagram of the display device provided in the embodiment of the present application, and the display device includes the display panel. The specific structure of the display panel has been described in detail in the above embodiments, and is not described herein again. Of course, the display device may be any electronic device with a display function, such as a mobile phone, a tablet computer, a notebook computer, an electronic paper book, or a television.
The display device provided by the embodiment of the present application has the beneficial effects of the organic light emitting display panel of the present application, and specific reference may be made to the description of the organic light emitting display panel in each of the above embodiments, which is not repeated herein.
The organic light-emitting display panel and the display device provided by the embodiments of the application have at least the following beneficial effects:
in the organic light-emitting display panel, a region which is located between the edge of the electronic element region and the edge of the display panel and has a distance of 10mm or less therebetween is an edge region. An anti-cracking groove body is arranged in the edge area SA, an inorganic layer in the driving circuit layer is not arranged in the anti-cracking groove body, and the anti-cracking groove body is covered by at least part of the film layer of the packaging layer. On one hand, the anti-cracking groove body can effectively enhance the effect of isolating water, oxygen and impurities of the organic light-emitting display panel in the edge region, and improve the reliability; on the other hand, the inorganic layer in the driving circuit layer which is easy to crack and crack to spread is removed from the anti-cracking groove body, so that the strength of the display panel in the marginal area is effectively improved, and the reliability is further improved.
The above description is only exemplary of the present application and should not be taken as limiting the present application, as any modification, equivalent replacement, or improvement made within the spirit and principle of the present application should be included in the scope of protection of the present application.
