When the main body 10 is pentagonal, hexagonal, heptagonal, or octagonal, the first regions 31 and the second regions 32 are alternately distributed around five sides, six sides, heptagonal, or eight sides of the main body 10.
The following description will be given only by taking the electronic device 1000 as a mobile phone. In this case, the main body 10 includes four sides and four corners.

The OLED device layer 314 is disposed on the substrate 311 and between the second inorganic layer 313 and the substrate 311.

Specifically, the first inorganic layer 312 and the second inorganic layer 313 may be deposited by a Chemical Vapor Deposition (CVD) method, wherein the thickness of each of the first inorganic layer 312 and the second inorganic layer 313 is about 1um, so that the first inorganic layer 312 and the second inorganic layer 313 have flexibility, thereby improving the flexibility of the display panel 100. After the second inorganic layer 313 and the first inorganic layer 312 are deposited, the planarization layer 3122 is used to perform a bonding operation, in which the thickness of the bonded planarization layer 3122 is at least 15um or more, so as to fill the gap 3120 between the first inorganic layers 312.

In the present application, the inorganic material units 3121 of the first inorganic layer 312 are disposed on the second inorganic layer 313 at intervals, and the intervals 3120 between the first inorganic layers 313 are disposed to reduce the thickness of the local inorganic layer of the first region 31, compared to an inorganic layer composed of two complete second inorganic layers 313, so that the stress applied to the first region 31 is effectively reduced. And the plurality of inorganic material units 3121 of the first inorganic layer 312 are spaced apart from each other to block the transmission of force, so that the external force resistance of the first region 31 is improved, and the first region 31 is effectively prevented from being broken.

The PI film has the characteristics of high and low temperature resistance, electrical insulation, adhesion, radiation resistance and the like, the traditional glass substrate is hard and fragile, and the PI film enables the display screen 100 to be flexible.
The material of the first inorganic layer 312 and the second inorganic layer 313 may be silicon oxide or silicon nitride. Because the silicon oxide and the silicon nitride have good hydrophobicity and oxidation resistance, the first inorganic layer 312 and the second inorganic layer 313 play a role in blocking water and oxygen from entering the OLED device layer 314, and the OLED device layer 314 is prevented from being invalid.
Referring to fig. 4, in another embodiment, the first region 31 may include a substrate 311, a first inorganic layer 312, a second inorganic layer 313, and an OLED device layer 314.

Similarly, the first inorganic layer 312 and the second inorganic layer 313 may be deposited by a CVD method, wherein the thicknesses of the first inorganic layer 312 and the second inorganic layer 313 are both about 1um, so that the first inorganic layer 312 and the second inorganic layer 313 have flexibility, thereby improving the flexibility of the display panel 100. After the first inorganic layer 312 and the second inorganic layer 313 are deposited, the planarization layer 3122 is used to perform a bonding operation, and the thickness of the bonded planarization layer 3122 is at least 15um or more, so as to fill the gap 3120 between the first inorganic layers 312. The flat layer 3122 is filled with glue and attached, so that there is no step difference between the surface of the main body 10 (shown in fig. 1) and the first region 31, and smooth connection can be maintained.
Similarly, the second inorganic layer 313 is disposed on the first inorganic layer 312 including the plurality of inorganic material units 3121 spaced from each other, and compared with an inorganic layer formed by two complete second inorganic layers 313, the provision of the space 3120 between the plurality of first inorganic layers 313 reduces the thickness of the local inorganic layer of the first region 31, so that the stress applied to the first region 31 is effectively reduced, and the design of the first inorganic layer 312 can block the transmission of force, thereby improving the capability of the first region 31 against external force, and effectively preventing the first region 31 from breaking.
