That is to say, framework 100 can adopt the integral type structure, framework 100 can support flexible display screen 200 by a large scale, a part of framework 100 is located between flexible display screen 200 and supersound fingerprint identification module 400, set up like this and can promote the support effect of supporter to flexible display screen 200, on the other hand directly installs supersound fingerprint identification module 400 in framework 100, thereby realize more function through less part, make electronic equipment's structure, manufacturing process and assembly process are all simpler, and electronic equipment's part reduces makes electronic equipment's attenuate and realize more easily. At the same time, the frame 100 has a large size, and thus has a better structural stability. In addition, because supersound fingerprint identification module 400 sets up in holding tank 110, the additional space that occupies of consequently supersound fingerprint identification module 400 is littleer, more is favorable to reducing electronic equipment's thickness.
As shown in fig. 1, in another alternative embodiment, the supporting body includes a frame body 100 and a reinforcing plate 300 that are connected, the reinforcing plate 300 is attached to a surface of the flexible display screen 200 facing the ultrasonic fingerprint identification module 400, and the frame body 100 is located on a side of the reinforcing plate 300 away from the flexible display screen 200. The reinforcing plate 300 comprises a first portion 310 and a second portion 320, the second portion 320 surrounds the first portion 310, and the ultrasonic fingerprint identification module 400 is attached to one surface of the first portion 310, which faces away from the flexible display screen 200. In this embodiment, the frame body 100 can support the reinforcing plate 300, and the reinforcing plate 300 can support the flexible display 200 in a large area, so as to improve the supporting effect of the supporting body on the flexible display 200. Meanwhile, the frame body 100 and the reinforcing plate 300 may be separately arranged, so that the structural design and material selection of the two are more flexible, the reinforcing plate 300 may be arranged to have a certain flexibility and at the same time provide a sufficient supporting force, and optionally, the reinforcing plate 300 may be a metal sheet such as a stainless steel sheet, a titanium alloy sheet, an aluminum sheet, or a copper sheet; the frame body 100 may be provided as a rigid structure, thereby increasing the structural strength and stability of the frame body 100.
The shape of the reinforcing plate 300 may be the same as the shape of the flexible display 200, and the sizes of the reinforcing plate and the flexible display 200 may be the same, so that the reinforcing plate 300 may completely cover the flexible display 200, thereby better supporting the flexible display 200. Optionally, the electronic device may be a foldable electronic device, and the flexible display screen 200 may be folded and unfolded, so as to realize folding and unfolding of the electronic device, at this time, the reinforcing plate 300 may support the flexible display screen 200, so as to meet a requirement of a user for operating the flexible display screen 200, so that the flexible display screen 200 is not easily deformed in a process of performing a touch operation by the user; and, the ultrasonic wave that supersound fingerprint identification module 400 sent can pass stiffening plate 300, therefore stiffening plate 300 need not correspond the regional trompil of fingerprint identification to further prevent that flexible display screen 200 from corresponding the regional part of fingerprint identification and taking place to warp.
The thickness direction of the flexible display 200 may be defined as a first direction, and it should be noted that the first direction is the thickness direction of the flexible display 200 in the unfolded state. Because the user will point 800 when putting the fingerprint identification region, the regional pressurized of fingerprint identification will drive ultrasonic fingerprint identification module 400 and remove on the first direction, consequently if ultrasonic fingerprint identification module 400 contacts with framework 100, will lead to ultrasonic fingerprint identification module 400 to receive the extrusion of framework 100 and damage.

As shown in fig. 2, the recess 130 may be a groove, and this embodiment provides a high structural strength to the frame body 100. In other embodiments, as shown in fig. 3, the recess 130 may be a through hole, and this embodiment may enable more parts of the ultrasonic fingerprint identification module 400 to be located in the recess 130, so that the frame body 100 is as close to the reinforcing plate 300 as possible, thereby being more beneficial to thinning the electronic device.
In order to improve the supporting effect, a reinforcing rib is disposed on a surface of the frame body 100 facing the flexible display panel 200, and the reinforcing rib supports the reinforcing plate 300. It should be noted that there may be one or more reinforcing ribs, and the reinforcing ribs may be arranged at intervals, so as to improve the supporting effect and reserve enough space for facilitating the arrangement of other components.
Alternatively, the frame body 100 and the reinforcing plate 300 may be disposed at an interval, and in order to connect the frame body 100 and the reinforcing plate, the electronic device may further include a first buffer layer 500, and the second portion 320 of the reinforcing plate 300 may be bonded to the frame body 100 through the first buffer layer 500. The first buffer layer 500 has a buffering effect, so that the first buffer layer 500 can achieve connection between the frame body 100 and the reinforcing plate 300, and can provide a buffering effect when a user presses the flexible display 200, thereby preventing other parts from being damaged due to the pressing operation of the user. The first buffer layer 500 may be a double-sided adhesive tape, the first buffer layer 500 may be made of a single material having adhesiveness, such as silicone, optical adhesive, etc., or may be made of a combination of multiple materials, and optionally, the first buffer layer 500 may include a polyester resin substrate layer and silicone layers disposed on both sides of the polyester resin substrate layer.
The thickness of the first portion 310 of stiffening plate 300 can be selected in a flexible way, when considering that the ultrasonic wave that supersound fingerprint identification module 400 transmitted pierces through stiffening plate 300, the interface department between stiffening plate 300 and the part above it can reflect the ultrasonic wave, consequently, can configure the thickness of first portion 310 into the ultrasonic wave that can make supersound fingerprint identification module 400 transmit and form the standing wave at the one side that stiffening plate 300 deviates from flexible display screen 200 with the back wave, thereby prevent that the back wave from weakening the ultrasonic wave that supersound fingerprint identification module 400 transmitted, with this promotion fingerprint identification effect.
The thickness of the second portion can also be flexibly selected, and in one embodiment, as shown in fig. 5, the thickness of the first portion 310 is greater than the thickness of the second portion 320, and the space below the second portion 320 is larger to facilitate the layout of the components in the electronic device. Alternatively, as shown in fig. 6, the thickness of the first portion 310 is smaller than that of the second portion 320, and the thickness of the second portion 320 is larger, so that the reinforcing plate 300 can provide a better supporting effect.
