[0024] The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all the embodiments of the present application. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative effort belong to the scope of protection of the present application.

[0025] Please refer to Figures 1 to 3 , Figure 1 is a schematic diagram of a three-dimensional structure of an electronic device 100 provided by a first embodiment of the present application; Figure 2 is a schematic diagram of a three-dimensional exploded structure of the electronic device 100 in Figure 1 ; Figure 3 is a schematic diagram of a three-dimensional exploded structure of the electronic device 100 in Figure 2Another perspective view of the electronic device 100 in the middle. The electronic device 100 of the first embodiment of the present application comprises a housing 20, a display device 30 arranged on the front of the housing 20, a mainboard 40 and a battery 50 arranged in the housing 20. The housing 20 comprises a middle frame 22 and a battery cover 25 covering the back of the middle frame 22, and the mainboard 40 and the battery 50 are located between the middle frame 22 and the battery cover 25. The display device 30 comprises a display screen 31 covering the front of the middle frame 22 and at least one pressure key 35, and the display screen 31 comprises a flat display area 312 and a bending display area 311 located on the opposite sides of the flat display area 312. The flat display area 312 and the bending display area 311 can be a large complete display screen or three display screens arranged separately and spliced together. Overall, the display screen 31 comprises a flat display area and a bending display area located on the opposite sides of the flat display area, and the flat display area and the bending display area can be three display screens arranged separately and spliced together or a large complete display screen. At least one pressure key 35 is arranged on the back of one of the bending display areas 311, and the pressure key 35 responds to the pressure signal received by the bending display area 311 to control the display device 30. Specifically, the pressure key 35 responds to the pressure signal received by the bending display area 311 and forms a key trigger signal to control the display device 30, so that the electronic device 100 can finally exert the corresponding key function.

[0026] In this embodiment, the electronic device 100 is, for example, but not limited to, a mobile phone, a tablet computer, a display, a liquid crystal panel, an OLED panel, a television, a smart watch, a VR head-mounted display, a vehicle-mounted display, and other any product and component with display function. The pressure key 35 is a pressure sensor arranged on the back of the bending display area 311 of the display screen 31, and the pressure sensor has the same function as the pressure sensor configured for the pressure key on the current electronic device. The working process and principle of the pressure sensor are known technologies, and will not be described here. The front refers to the same face as the light-emitting surface of the display screen, and the back refers to the face away from the light-emitting surface of the display screen.

[0027] The electronic device 100 provided by this invention has a display screen 31 with bent display areas 311 on opposite sides. At least one pressure button 35 is disposed on the back side of one of the bent display areas 311. When one of the bent display areas 311 is pressed, the pressure button 35 responds to the pressure signal received by the bent display area 311 and generates a button trigger signal to control the display device 30. Since the pressure button 35 is disposed on the back side of the bent display area 311, it is convenient to operate as long as the corresponding pressure button 35 is pressed directly on the bent display area 311 when the pressure button 35 needs to be used.

[0028] Preferably, such as Figure 1 As shown, a pressure button area 313 is provided on the front of the curved display area 311 of the display screen 31, corresponding to the pressure button 35. The pressure button area 313 is used to receive pressure signals to drive the pressure button 35 to produce displacement. Specifically, when the pressure button area 313 is pressed, the pressure button area 313 receives the pressure signal and drives the pressure button 35 to move, thereby causing the pressure button 35 to respond to the pressure signal received by the pressure button area 313 and send a button trigger signal. The pressure button 35 is arranged opposite to the pressure button area 313, that is, the orthogonal projection of the pressure button 35 on the corresponding curved display area 311 is located within the pressure button area 313. When a user presses the pressure button area 313, the pressure button area 313 receives a pressure signal (i.e., the pressure button area 313 deforms), which in turn drives the pressure button 35 to move, so that the pressure button 35 responds to the pressure signal received by the pressure button area 313 and generates a button trigger signal to control the display device 30, and ultimately enables the electronic device 100 to perform the corresponding button function.

[0029] In this embodiment, the pressure button 35 is attached to the back of the bent display area 311, so that the pressure button 35 corresponds to the pressure button area 313. When the pressure button area 313 is pressed, the pressure button area 313 receives a pressure signal, and the pressure button 35 can easily respond to the pressure signal.

[0030] like Figure 2 and Figure 3As shown, the middle frame 22 includes a generally rectangular support plate 221 and side walls 223 disposed on opposite sides of the support plate 221. Each side wall 223 extends outward from the support plate 221 and inclined towards the back. The support plate 221 and the two side walls 223 form an accommodating space 224, which is used to accommodate the motherboard 50 and the battery 60. Connecting grooves 225 are respectively provided on opposite sides of the front of the support plate 221. Each connecting groove 225 extends along the length of the support plate 221 and passes through opposite end faces of the support plate 221. The connecting groove 225 is used to accommodate double-sided tape or adhesive. A sealing groove 226 is provided on the outer side of each side wall 223 away from the support plate 221. The sealing groove 226 extends along the length of the side wall 223 and passes through opposite end faces of the support plate 221. A sealing strip or sealant is provided in the sealing groove 226 to prevent dust or debris from entering the electronic device 100.

[0031] Each curved display area 311 bends from the side corresponding to the flat display area 312 toward the back to form a waterfall screen. The flat display area 312 and the two curved display areas 311 enclose a receiving space 315, and the front of the middle frame 22 is accommodated within the receiving space 315.

[0032] Specifically, such as Figure 6 As shown, in this embodiment, the display screen 31 includes a light-emitting device layer 3101, a polarizer layer 3102 stacked on the front side of the light-emitting device layer 3101, a touch module layer 3105 attached to the front side of the polarizer layer 3102 by a transparent optical adhesive layer 3103, a support film layer 3106 stacked on the back side of the light-emitting device layer 3101, a support sheet 3108 attached to the back side of the support film layer 3106 by an optical adhesive layer 3107, a substrate 3110 attached to the back side of the support sheet 3108 by an ultra-thin double-sided adhesive layer 3109, and a cover plate 3112 attached to the front side of the touch module layer 3105 by an ultra-thin optical adhesive layer 3111. The light-emitting device layer 3101 is a flexible polyimide layer, on which circuits and vapor-deposited light-emitting devices are provided. The opposite sides of each layer of the display screen 31 are bent toward the opposite sides of the middle frame 22 to form two bent display areas 311. The light-emitting device layer 3101 and the touch module layer 3105 are electrically connected to the flexible circuit board, and then electrically connected to the motherboard 50 of the electronic device 100 through the flexible circuit board.

[0033] The cover plate 3112, the touch module layer 3105, the polarizer layer 314, the first optical adhesive layer 3103, and the polarizer layer 3102 are all transparent. The cover plate 3112, the substrate 3110, and the other layers of the display screen 31 are all arranged in a circular arc shape on opposite sides. The cover plate 3112 is a thin, flexible, and bendable sheet that is transparent to light. Preferably, the cover plate 3112 is an ultra-thin glass cover sheet with a thickness of microns, specifically, the thickness of the ultra-thin glass cover sheet ranges from 5 microns to 80 microns. The substrate 3110 is a flexible support sheet that can be, but is not limited to, a copper foil sheet, a liquid metal sheet, a plastic sheet, or other thin sheets made of suitable materials. In this embodiment, the substrate 3110 is a liquid metal sheet.

[0034] The liquid metal in the present application refers to an alloy that is heated to a molten state and then cooled at an ultra-fast speed, so that the alloy lattice cannot be ordered and crystallized, and is solidified. Because it is in a non-crystalline state, it is also called amorphous alloy, liquid metal, or metal glass. The characteristics of liquid metal are long-range disorder (short-range order), metastable state, certain degree of physical property isotropy, no exact melting point, glass transition temperature point, etc. It has the characteristics of solid, metal, and glass, and can have high strength, high hardness, plasticity, thermal conductivity, and wear resistance under certain conditions. That is, the liquid metal in the present application is essentially solid at room temperature, but its certain characteristics are close to those of a liquid, so it is called liquid metal. The liquid metal can be an alloy material of one or more materials such as copper, titanium, iron, zirconium, silver, nickel, gallium, gold, antimony, cadmium, zinc, indium, silicon, etc. Preferably, the specific metal can obtain lower elastic modulus, hardness, ductility, and other mechanical properties.

[0035] In other embodiments, the cover plate 3112 can also be a flexible transparent cover plate, such as a transparent PET film layer or a PI film layer.

[0036] As shown in Figure 2 and Figure 3 The electronic device 100 further includes a connecting adhesive strip 70 and an elastic support strip 80. The connecting adhesive strip 70 is used to connect the middle frame 22 and the display screen 31. The support strip 80 is arranged between each bent display area 311 and the corresponding side wall 223 to support the bent display area 311.

[0037] As shown in Figures 1 to 7 , when assembling the electronic device 100, the support strips 80 are respectively attached to the two side walls 223 of the middle frame 22, so that a gap 82 is formed between the two support strips 80 on one side wall 223 (as shown in Figure 4As shown), the notch 82 is used to accommodate the pressure button 35; the connecting strip 70 is respectively attached to the two connecting grooves 225 of the middle frame 22; the pressure button 35 is attached to the back of one of the bent display areas 311, so that the pressure button 35 faces the pressure button area 313; the back of the display screen 31 is covered over the front of the middle frame 22, so that the front of the middle frame 22 is attached to the back of the display screen 31, and the connecting strip 70 is attached to the back of the middle frame 22. The two bent display areas 311 are respectively bent and extended to the opposite side walls 223 of the middle frame 22. Each bent display area 311 is connected to the... The side walls 223 of the mid-frame 22 form an accommodating space 37. The support strip 80 is housed within the corresponding accommodating space 37 and supported on the back of the two bent display areas 311. At this time, the pressure button 35 is housed within the corresponding accommodating space 37. Furthermore, the back of the pressure button 35 is housed within the gap 82, and there is a gap between the back of the pressure button 35 and the front of the corresponding side wall 223. Specifically, the depth of the gap is between 0.3mm and 0.8mm. The motherboard 50 and battery 60 are installed within the accommodating space 224 of the mid-frame 22, and then the battery cover 25 is placed over the battery 60 and connected to the mid-frame 22. At this time, the two bent display areas 311 of the display screen 31 bend and extend to the sides of the two side walls 223 of the mid-frame 22, forming a waterfall-style electronic device.

[0038] When the pressure button 35 of the electronic device 100 is used, pressing the pressure button area 313 causes the pressure button area 313 to receive a pressure signal, thereby driving the pressure button 35 to move. This causes the pressure button 35 to respond to the pressure signal received by the bending display area 311 and generate a button trigger signal to control the display device 30. Ultimately, the electronic device 100 can perform the corresponding button functions, making it convenient and easy to operate. Moreover, the structure is simple, and the pressure button 35 occupies a small amount of internal space in the electronic device 100, which helps to reduce the overall thickness of the electronic device 100.

[0039] Preferably, an elastic sealing strip is provided between the two opposite sides of the battery cover 25 and the two opposite sides of the middle frame 22.

[0040] In other embodiments, each sidewall 223 has a positioning groove on its front side along its length, and the back of the support bar 80 can be inserted into the positioning groove, which can further reduce the overall thickness of the electronic device 100.

Specifically, each bent display area 311 also includes a light emitting device layer 3101, a polaroid layer 3102, a touch module layer 3105, a support film layer 3106, a support sheet 3108, a substrate 3110 and a cover plate 3112 stacked by an optical adhesive layer or a double-sided adhesive layer, the back surface of the substrate 3110 of the bent display area 311 is provided with a positioning hole 3115 corresponding to the pressure key area 313, and the pressure key 35 is accommodated in the positioning hole 3115, so that the pressure key 35 is fixedly connected to the corresponding bent display area 311. The use method of the pressure key 35 of the electronic device 100a of the second embodiment of the present application is the same as that of the first embodiment, and will not be repeated here. In this embodiment, by pressing the pressure key area 313, the pressure key area 313 receives a pressure signal to drive the pressure key 35 to displace, and the pressure key 35 responds to the pressure signal received by the pressure key area 313 and forms a key trigger signal to control the display device 30, so that the electronic device 100 can finally exert corresponding key functions, which is convenient to use and easy to operate. In addition, since the back surface of the substrate 3110 of the bent display area 311 is provided with a positioning hole 3115, the pressure key 35 is at least partially accommodated in the positioning hole 3115, which can further reduce the overall thickness of the electronic device 100a.

[0042] Please refer to Figure 9 , Figure 9is a partial cross-sectional structure schematic view of the electronic device 100b provided by the third embodiment of the present application. The electronic device 100b provided by the third embodiment of the present application is similar to the second embodiment, with the difference that in the third embodiment, the back of the substrate 3110 of the bent display area 311 is provided with a positioning hole 3116 corresponding to the pressure key area 313, the positioning hole 3116 communicates with the accommodating space 37, and the positioning hole 3116 penetrates the substrate 3110, and the pressure key 35 is positioned in the positioning hole 3116. The use method of the pressure key 35 of the electronic device 100b of the third embodiment of the present application is the same as that of the first embodiment, and will not be repeated here. In this embodiment, the pressure key area 313 receives a pressure signal by pressing the pressure key area 313 to drive the pressure key 35 to displace, and the pressure key 35 responds to the pressure signal received by the pressure key area 313 and forms a key trigger signal to control the display device 30, so that the electronic device 100 can finally exert corresponding key functions, which is convenient to use and easy to operate. In addition, since the positioning hole 3116 on the back of the substrate 3110 of the bent display area 311 penetrates the substrate 3110, most or all of the pressure key 35 is accommodated in the positioning hole 3115, which can further reduce the overall thickness of the electronic device 100a.

[0043] Please refer to Figure 10 , Figure 10 is a partial cross-sectional structure schematic view of the electronic device 100c provided by the fourth embodiment of the present application.

The use method of the pressure key 35 of the electronic device 100c of the fourth embodiment of the present application is the same as that of the first embodiment, and will not be repeated here.

[0044] Please refer to Figure 11 , Figure 11is a partial cross-sectional structure schematic view of the electronic device 100d provided by the fifth embodiment of the present application. The electronic device 100d provided by the fifth embodiment of the present application is similar to the first embodiment, except that in the fifth embodiment, an elastic sealing member 90 is arranged between the sidewall of each bent display area 311 and the corresponding sidewall 223 of the middle frame 22, which prevents dust or sundries from entering between the middle frame 22 and the display screen 31. By pressing the pressure key area 313, the pressure key area 313 receives a pressure signal to drive the displacement of the pressure key 35 and the deformation of the elastic sealing member 90. The pressure key 35 responds to the pressure signal received by the pressure key area 313 to form a key trigger signal to control the display device 30, so that the electronic device 100 can finally exert the corresponding key function, which is convenient to use and easy to operate.

[0045] Please refer to Figure 12 and Figure 13 , Figure 12 is a partial exploded perspective structure schematic view of the electronic device 100e provided by the sixth embodiment of the present application. Figure 13 is an end structure schematic view of the electronic device 100e provided by the sixth embodiment of the present application. The electronic device 100e provided by the sixth embodiment of the present application is similar to the first embodiment, except that in the sixth embodiment, the middle frame 22 is provided with an elastic extension 227 corresponding to the pressure key area 313, and the pressure key 35 is arranged on the extension 227. The side of the extension 227 is connected to the side of the corresponding bent display area 311 provided with the pressure key area 313, that is, the side of the extension 227 away from the support plate 221 is connected to the side of the corresponding bent display area 311 away from the flat display area 312, and the extension 227 is directly opposite the pressure key area 313. The pressure key area 313 is used to receive a pressure signal to drive the displacement of the extension 227, and the pressure key 35 displaces with the extension 227. Specifically, the curved pressure key area 313 pushes the extension 227 to deform and displace, and the pressure key 35 displaces with the extension 227. The pressure key 35 responds to the pressure signal received by the bent display area 311 and forms a key trigger signal to control the display device 30, so that the electronic device 100 can finally exert the corresponding key function, which is convenient to use and easy to operate.

[0046] Preferably, the extension 227 is located adjacent to the end of the corresponding side wall 223, the pressure key area 313 is located adjacent to the end of the corresponding bending display area 311, and the extension 227 is opposite to the pressure key area 313, so that pressing the pressure key area 313 is easier to deform, thereby facilitating the extension 227 to be deformed, so that the pressure key 35 arranged on the extension 227 is easier to respond to the pressure signal received by the bending display area 311 and form a key trigger signal.

[0047] In the embodiment, the extension 227 is an elastic sheet extending from the side wall of the support plate 221 to the back and outwardly; the pressure key 35 is attached or bonded to the front of the extension 227; preferably, the pressure key 35 is located on the side of the front of the extension 227 away from the support plate 221.

[0048] Please refer to Figure 14 , Figure 14 is a partial end structure schematic diagram of an electronic device 100f provided by the seventh embodiment of the present application. The electronic device 100f provided by the seventh embodiment of the present application is similar to the sixth embodiment, and the difference lies in that the extension 227 is provided with a connecting hole 2270, and the pressure key 35 is accommodated in the connecting hole 2270, which not only facilitates the fixed connection of the pressure key 35 and the extension 227, but also facilitates the reduction of the internal space of the electronic device occupied by the pressure key 35, and facilitates the reduction of the overall thickness of the electronic device. Preferably, the connecting hole 2270 is located on the side of the front of the extension 227 away from the support plate 221, so that when the bending display area 311 provided with the pressure key area 313 pushes the extension 227 to deform when the pressure key area 313 is pressed, the displacement of the pressure key 35 is longer, which is more conducive to the pressure key 35 to respond to the pressure signal received by the bending display area 311 and form a key trigger signal.
