In consideration of the fact that the bottom structure is not compact when the area does not include the adhesive layer 24 and the support layer 25, and the flexible display panel 26 is deformed due to external force, the flexible display panel 26 is supported by the support adhesive material 91 through the opening, so that the flexible display panel 26 is prevented from being deformed.

In particular, the supporting glue 91 comprises three layers, respectively two double-faced glue layers and a plastic material between the two double-faced glue layers, which may for example comprise polyethylene. The plastic material is used to support the flexible display panel 26 at the corners of the middle frame 30 to prevent the flexible display panel 26 from being deformed, and the double-sided tape is used to bond the flexible display panel 26 and the middle frame 30 together. During preparation, the supporting adhesive material 91 is formed at the opening, and then the flexible display panel 26 is attached to the supporting adhesive material 91, so that when the flexible display panel 26 is attached, the flexible display panel 26 is not deformed due to stress generated by bending at the opening when the supporting adhesive material 91 is formed.

Optionally, fig. 17 is a schematic structural diagram of an adhesive layer 24 according to an embodiment of the present invention, and as shown in fig. 17, the adhesive layer 24 includes a first adhesive layer 241, a metal layer 242, and a second adhesive layer 243, which are sequentially stacked.

The metal layer 242 includes a copper foil metal material, and the copper foil metal has good heat dissipation, shielding and insulation performance, so that normal heat dissipation of the second display module 20 is ensured, interference of other signals is avoided, and normal display of the second display module 20 is ensured.

Optionally, with continued reference to fig. 15 and 16, the second display module 20 further includes a polarizer 27, an optically transparent adhesive 28, and a cover 29. Polarizer 27 is located on the side of flexible display panel 26 remote from support layer 25, cover 29 is located on the side of polarizer 27 remote from flexible display panel 26, and optically clear adhesive 28 is located between polarizer 27 and cover 29. Polarizer 27 and cover 29 are bonded together by optically clear adhesive 28.

The polarizer 27 can prevent ambient light from being incident on the metal electrode of the second display module 20 and then reflected out, thereby affecting the display and improving the contrast of the second display module 20. The cover plate 29 may be a glass cover plate or a color filter, and the cover plate 29 needs to ensure flexibility and bendability, which has high light transmittance. Meanwhile, the cover 29 serves as an outermost protective layer of the second display module 20, so that the second display module 20 is protected by impact, scratch, etc. when the second display module 20 is subjected to impact.

It is to be noted that the foregoing is only illustrative of the preferred embodiments of the present invention and the technical principles employed. It will be understood by those skilled in the art that the present invention is not limited to the particular embodiments described herein, but is capable of various obvious changes, rearrangements and substitutions as will now become apparent to those skilled in the art without departing from the scope of the invention. Therefore, although the present invention has been described in greater detail by the above embodiments, the present invention is not limited to the above embodiments, and may include other equivalent embodiments without departing from the spirit of the present invention, and the scope of the present invention is determined by the scope of the appended claims.
