Description

Technical Field

[0001] This application belongs to the field of electronic equipment technology, and specifically relates to an electronic device. Background Technology

[0002] In related technologies, to ensure bending performance, flexible foldable screens incorporate a mesh design at the bending points of the screen support backplate to achieve stretchability during bending. After unfolding, the reduced springback of the backplate after bending decreases the support force provided by the screen support plate, resulting in more noticeable creases after unfolding. Summary of the Invention

[0003] This application aims to provide an electronic device that can solve the problem that after a flexible folding screen is unfolded, the reduced elasticity of the back panel after bending reduces the support force provided by the screen support plate to the flexible folding screen, resulting in more obvious creases after the flexible folding screen is unfolded.

[0004] To solve the above-mentioned technical problems, this application is implemented as follows:

[0005] In a first aspect, embodiments of this application provide an electronic device, including a display layer and a first support layer; the display layer includes a first bent portion, a first display portion and a second display portion, the first display portion and the second display portion being located on both sides of the first bent portion; the first support layer includes a first support portion, a second support portion and a second bent portion; the first support portion is connected to the first display portion; the second support portion is connected to the second display portion; both sides of the second bent portion are connected to the first support portion and the second support portion respectively, and are disposed opposite to the first bent portion, wherein the second bent portion includes a protrusion, and when the display layer is in an unfolded state, the protrusion protrudes in a direction closer to the display layer, or the protrusion protrudes in a direction away from the display layer.

[0006] In embodiments of this application, the electronic device includes a display layer, which includes a first bending portion. While displaying information, the display layer can be folded via the first bending portion, thereby increasing the size of the screen assembly and improving its display effect. The display layer also includes a first display section and a second display section, located on opposite sides of the first bending portion. The electronic device further includes a first support layer, which includes a first support section, a second support section, and a second bending portion. The first support section is connected to the first display section, and the second support section is connected to the second display section, thereby supporting the first and second display sections and improving the stability of the electronic device during folding and unfolding.

[0007] The second bending portion includes a protrusion. When the display layer is in the unfolded state, the protrusion protrudes towards the display layer or towards the display layer, thereby increasing the strength of the second bending portion. This results in the second bending portion having stronger rebound capability when switching from the folded state to the unfolded state. After the electronic device switches to the unfolded state, the second bending portion has stronger support capability for the first bending portion, further reducing the crease after the first bending portion is unfolded and improving the display effect of the electronic device when it is in the unfolded state.

[0023] The following is combined Figures 1 to 7 An electronic device according to an embodiment of the present invention is described.

[0024] like Figure 1 , Figure 2 and Figure 3 As shown, an electronic device according to some embodiments of the present invention includes a display layer 100 and a first support layer 200; the display layer 100 includes a first bent portion 110, a first display portion 120, and a second display portion 130, the first display portion 120 and the second display portion 130 being located on both sides of the first bent portion 110; the first support layer 200 includes a first support portion 210, a second support portion 220, and a second bent portion 230; the first support portion 210 is connected to the first display portion 120; the second support portion 220 is connected to the second display portion 130; wherein, the second bent portion 230 includes a protrusion 234, which, when the display layer 100 is in an unfolded state, extends towards the display layer 100 ( Figure 2 The protrusion (in the direction indicated by the middle arrow U) or the protrusion 234 protrudes away from the display layer 100. Figure 2 (The direction indicated by the middle arrow Z) is raised.

[0025] In embodiments of this application, the electronic device includes a display layer 100, which includes a first bending portion 110. While displaying information, the display layer 100 can be folded via the first bending portion 110, thereby increasing the size of the screen assembly and improving its display effect. The display layer 100 also includes a first display portion 120 and a second display portion 130, which are located on opposite sides of the first bending portion 110. The electronic device also includes a first support layer 200, which includes a first support portion 210, a second support portion 220, and a second bending portion 230. The first support portion 210 is connected to the first display portion 120, and the second support portion 220 is connected to the second display portion 130. The first and second support portions 210 and 220 support the first and second display portions 120 of the display layer 100, improving the stability of the electronic device during folding and unfolding.

[0026] The display layer 100 also includes a first display unit 120 and a second display unit 130. The second display unit 130 is connected to the first display unit 120 via a first bending portion 110, allowing the second display unit 130 to be folded or unfolded with the first display unit 120 via the first bending portion 110, thereby increasing the size of the electronic device and improving its display effect. The first display unit 120 is fitted with a first support portion 210, thereby supporting the first display unit 120 and improving the smoothness of the folding or unfolding process of the electronic device. The second display unit 130 is fitted with a second support portion 220, thereby supporting the second display unit 130 and improving the smoothness of the folding or unfolding process of the electronic device.

[0027] The second bending portion 230 includes a protrusion 234. When the display layer 100 is in the unfolded state, the protrusion 234 protrudes towards the display layer 100 or towards the display layer 100, thereby increasing the strength of the second bending portion 230. This results in the second bending portion 230 having a stronger rebound capability when switching from the folded state to the unfolded state, and thus the second bending portion 230 having a greater self-flattening force. After the electronic device switches to the unfolded state, the second bending portion 230 has a stronger support capability for the first bending portion 110, further reducing the crease after the first bending portion 110 is unfolded, and improving the display effect of the electronic device when it is in the unfolded state.

[0028] Specifically, the protrusion 234 can protrude either towards the display layer 100 or away from the display layer 100.

[0029] When there are multiple protrusions 234, some of the protrusions 234 may protrude towards the display layer 100, while other protrusions 234 may protrude away from the display layer 100. Alternatively, all of the protrusions 234 may protrude towards the display layer 100, or all of the protrusions 234 may protrude away from the display layer 100.

[0030] Optionally, the first display part 120, the second display part 130 and the first bending part 110 are an integral structure.

[0031] The side of the first display portion 120 closest to the first bending portion 110 is the third bending portion 122, and the side of the first display portion 120 furthest from the first bending portion 110 is the first flat portion 124. The bending direction of the third bending portion 122 is opposite to the bending direction of the first bending portion 110.

[0032] The side of the second display portion 130 closest to the first bending portion 110 is the fourth bending portion 132, and the side of the second display portion 130 furthest from the first bending portion 110 is the second flat portion 134. The bending direction of the fourth bending portion 132 is opposite to the bending direction of the first bending portion 110.

[0033] The first flattening part 124 is connected to the first bending part 110 via the third bending part 122, and the second flattening part 134 is connected to the first bending part 110 via the fourth bending part 132. When the electronic device is in a folded state, the third bending part 122, the first bending part 110 and the fourth bending part 132 form a teardrop-shaped structure.

[0034] According to some embodiments of the present invention, the second bending portion 230 further includes a connecting portion 232, one end of which is connected to the first support portion 210, and the other end of which is connected to the second support portion 220; the first side of the protrusion 234 is connected to the connecting portion 232, and the second side of the protrusion 234 is a free side.

[0035] In this embodiment, the second bending portion 230 further includes a connecting portion 232. The first side of the protrusion 234 is connected to the connecting portion 232, and the second side of the protrusion 234 is a free side. When the electronic device is in the unfolded state, the second side of the protrusion 234 extends away from the display layer 100, so that there is a certain angle between the protrusion 234 and the connecting portion 232. This makes the second bending portion 230 have a stronger rebound ability when switching from the folded state to the unfolded state, and thus the second bending portion 230 has a greater self-flattening force. After the electronic device switches to the unfolded state, the second bending portion 230 has a stronger support ability for the first bending portion 110, further reducing the crease after the first bending portion 110 is unfolded, and improving the display effect when the electronic device is in the unfolded state.

[0036] Specifically, the first side of the protrusion 234 is connected to the connecting part 232, and the second side of the protrusion 234 is a free side. When the electronic device is in the unfolded state, the second side of the protrusion 234 extends away from the display layer 100. When the second bending part 230 switches from the unfolded state to the folded state, the connecting part 232 bends, and the connecting part 232 causes the protrusion 234 to bend together. While the protrusion 234 bends with the connecting part 232, the second side of the protrusion 234 moves towards the display layer 100 until the protrusion 234 moves to be flush with the connecting part 232. Then, the connecting part 232 and the protrusion 234 bend to a predetermined angle. Because the protrusion 234 moves to be flush with the connecting part 232, there is elastic deformation between the protrusion 234 and the connecting part 232.

[0037] During the transition of the second bending portion 230 from a folded state to an unfolded state, due to the elastic deformation between the protrusion 234 and the connecting portion 232, the protrusion 234 will return to its unfolded state under the drive of the elastic force. That is, the second side of the protrusion 234 will extend away from the display layer 100, thereby giving the second bending portion 230 a stronger rebound capability. Furthermore, since the second side of the protrusion 234 extends away from the display layer 100, there is a certain angle between the thickness direction of the protrusion 234 and the bending direction of the second bending portion 230. The protrusion 234 can resist the bending of the connecting portion 232, thus giving the second bending portion 230 a stronger support capability, thereby improving the support effect of the second bending portion 230 on the first bending portion 110.

[0038] Optionally, the protrusion 234 extends along the extending direction of the connecting portion 232.

[0039] Optionally, such as Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, the display layer 100 includes a cover layer 300, a panel layer 400, and a second support layer 500.

[0040] The cover plate layer 300 includes a cover plate 310, a first adhesive layer 320, a glass plate 330, and a second adhesive layer 340. The cover plate 310 is bonded to the glass plate 330 through the first adhesive layer 320, and the second adhesive layer 340 is disposed on the side of the glass plate 330 away from the cover plate 310.

[0041] The cover plate 310 is a transparent polyimide plate with a hardened coating (PL+HC, Polyimide+Hard Coating).

[0042] The first adhesive layer 320 and the second adhesive layer 340 are optical adhesives (OCA, Optically Clear Adhesive).

[0043] Glass plate 330 is ultra-thin glass (UTG).

[0044] The panel layer 400 includes a display panel 410 and a protective film 420 (P-Film, Protective Film).

[0045] The display panel 410 is bonded to the second adhesive layer 340, and the protective film 420 is bonded to the side of the display panel 410 away from the second adhesive layer 340.

[0046] The second support layer 500 is a panel support layer.

[0047] The panel support layer includes a third adhesive layer 510, a flexible substrate 520 and a fourth adhesive layer 530. The third adhesive layer 510 is attached to the protective film 420. The third adhesive layer 510 and the fourth adhesive layer 530 are respectively disposed on both sides of the flexible substrate 520. The fourth adhesive layer 530 is attached to the first support layer 200.

[0048] The third adhesive layer 510 and the fourth adhesive layer 530 are pressure-sensitive adhesives (PSA).

[0049] The flexible substrate 520 is a polyimide (PI) substrate.

[0050] Optionally, the first support layer 200 is a thin-walled structure.

[0051] The first support layer 200 can be made of carbon fiber, metal or ultra-thin glass.

[0052] The thickness of the first support layer 200 is greater than or equal to 0.08 mm and less than or equal to 0.15 mm.

[0053] Specifically, the second side of the protrusion 234 extending away from the display layer 100 means that the overall extension trend of the protrusion 234 has a tendency to extend away from the display layer 100, rather than that the extension direction of the protrusion 234 is parallel to the direction away from the display layer 100.

[0054] According to some embodiments of the present invention, such as Figure 1 , Figure 2 and Figure 3 As shown, the first support portion 210 is provided with a plurality of first through holes 212, which are located on the side of the first support portion 210 near the second bending portion 230 and extend along the length direction of the first bending portion 110; and / or the second support portion 220 is provided with a plurality of second through holes 222, which are located on the side of the second support portion 220 near the second bending portion 230 and extend along the length direction of the first bending portion 110.

[0055] In this embodiment, the first support portion 210 is provided with a plurality of first through holes 212. The plurality of first through holes 212 are located on the side of the first support portion 210 near the second bending portion 230. The plurality of first through holes 212 extend along the length direction of the first bending portion 110, thereby enabling the area of ​​the first support portion 210 near the second bending portion 230 to have a certain tensile capacity, reducing the stress generated by the reverse folding when the electronic device is in a folded state, and improving the stability of the first support portion 210 during the unfolding and folding process of the electronic device.

[0056] The second support portion 220 is provided with a plurality of second through holes 222. The plurality of second through holes 222 are located on the side of the second support portion 220 near the second bending portion 230. The plurality of second through holes 222 extend along the length direction of the first bending portion 110, thereby giving the area of ​​the second support portion 220 near the second bending portion 230 a certain tensile capacity and improving the stability of the second support portion 220 during the unfolding and folding of the electronic device.

[0057] Optionally, the area of ​​the first support portion 210 with multiple first through holes 212 is opposite to the third bending portion 122 of the display layer 100. Thus, during the bending process of the third bending portion 122, the first support portion 210 has a certain tensile capacity, which prevents the first support portion 210 from squeezing the third bending portion 122 and makes the bending process of the third bending portion 122 more stable.

[0058] Optionally, the area of ​​the second support portion 220 with multiple second through holes 222 is opposite to the fourth bending portion 132 of the display layer 100. Thus, during the bending process of the fourth bending portion 132, the second support portion 220 has a certain tensile capacity, which prevents the second support portion 220 from squeezing the fourth bending portion 132 and makes the bending process of the fourth bending portion 132 more stable.

[0059] Optionally, the first through hole 212 is an elongated hole extending along the length direction of the first bend 110, and a plurality of first through holes 212 are arranged along the length direction of the first bend 110 and along the width direction of the first bend 110. Figure 1 Multiple rows of first through holes 212 are arranged in the direction indicated by the middle arrow X. The first through holes 212 in adjacent rows are staggered, thereby ensuring that the area of ​​the first support part 210 with the first through holes 212 has a certain tensile capacity and a certain strength, thereby improving the support capacity of the first support part 210 for the third bending part 122.

[0060] The second through hole 222 is an elongated hole extending along the length direction of the first bending portion 110. Multiple second through holes 222 are arranged along the length direction of the first bending portion 110, and multiple rows of second through holes 222 are arranged along the width direction of the first bending portion 110. The second through holes 222 in adjacent rows of multiple rows of second through holes 222 are staggered, thereby ensuring that the area of ​​the second support portion 220 with the second through holes 222 has a certain tensile capacity and a certain strength, thereby improving the support capacity of the second support portion 220 for the fourth bending portion 132.

[0061] Optionally, the first through hole 212 and the second through hole 222 are prepared by an etching process.

[0062] Alternatively, the first through-hole 212 and the second through-hole 222 can be replaced by half-etched stripes.

[0063] According to some embodiments of the present invention, there are multiple second bends 230, and the multiple second bends 230 are arranged side by side.

[0064] In this embodiment, multiple second bending portions 230 are arranged in parallel, so that the second bending portions 230 can deform accordingly according to the needs of unfolding or folding the electronic device, thereby improving the smoothness of the unfolding or folding process of the electronic device.

[0065] Optionally, a plurality of second bends 230 are along the length direction of the first bend 110. Figure 1 Arranged at intervals (in the direction indicated by the middle arrow Y), the second bending portion 230 includes a connecting portion 232. One end of the connecting portion 232 is connected to the first support portion 210, and the other end of the connecting portion 232 is connected to the second support portion 220. Thus, the connecting portion 232 supports the first bending portion 110 of the display layer 100, improving the flatness of the first bending portion 110 after the display layer 100 is unfolded. Furthermore, since multiple second bending portions 230 are arranged at intervals along the length direction of the first bending portion 110, there is a certain gap between two adjacent second bending portions 230. During the folding process of the second bending portion 230, the second bending portion 230 has a certain elastic deformation capability and tensile capability, thus making the folding and unfolding of the display layer 100 smoother.

[0066] According to some embodiments of the present invention, such as Figure 2 and Figure 5 As shown, there are multiple protrusions 234, which are respectively disposed on both sides of the connecting portion 232; there is a first gap 236 between the protrusions 234 of two adjacent second bend portions 230.

[0067] In this embodiment, there are multiple protrusions 234, which are respectively disposed on both sides of the connecting portion 232. This further enhances the resilience of the second bending portion 230, thereby improving the support effect of the second bending portion 230 on the first bending portion 110. Furthermore, the multiple protrusions 234, disposed on both sides of the connecting portion 232, ensure that the resilience force from the protrusions 234 is more evenly distributed on the connecting portion 232, reducing the probability of local deformation of the connecting portion 232 and further improving the stability of the second bending portion 230's support for the first bending portion 110. A first gap 236 is provided between the protrusions 234 of two adjacent second bends 230, so that the protrusions 234 have a certain amount of movement space. During the process of switching the electronic device from the unfolded state to the folded state, the probability of interference between the protrusions 234 of two adjacent second bends 230 is reduced, and the stability of the second bend 230 supporting the first bend 110 is further improved.

[0068] Optionally, each second bend 230 includes a connecting portion 232 and two protrusions 234, with the two protrusions 234 respectively disposed on both sides of the connecting portion 232 in the length direction of the first bend 110.

[0069] Optionally, such as Figure 5 As shown, the thickness t of the second bending portion 230 is 0.05 mm, the cross-sectional shape of the second bending portion 230 is trapezoidal, the width W1 of the second bending portion 230 is 0.5 mm, the width a of the protrusion 234 is 0.15 mm, and the width b of the first gap 236 between two adjacent second bending portions 230 is 0.12 mm.

[0070] The thickness t of the second bending portion 230 is 0.05 mm, the cross-sectional shape of the second bending portion 230 is arc-shaped, the radius of curvature R1 of the second bending portion 230 is 0.3 mm, and the width b of the first gap 236 between two adjacent second bending portions 230 is 0.12 mm.

[0071] According to some embodiments of the present invention, such as Figure 5 and Figure 6 As shown, on a cross-section of the second bend 230, the protrusion 234 extends in a straight line or arc, and there is a first included angle between the connecting portion 232 and the protrusion 234.

[0072] In this embodiment, on one cross-section of the second bending portion 230, the protrusion 234 extends in a straight line or arc. When the electronic device is in the unfolded state, the surface of the second bending portion 230 is flatter, thereby improving the support effect of the second bending portion 230 on the first bending portion 110 and further reducing the creases when the electronic device is in the unfolded state.

[0073] Along the length of the first bend 110, the connecting portion 232 extends in a straight line and the protrusion 234 extends in an arc. When the electronic device switches from a folded state to an unfolded state, the second bend 230 has a stronger rebound capability, thereby improving the support capability of the second bend 230 for the first bend 110 and further reducing the creases when the electronic device is in the unfolded state.

[0074] The connecting part 232 and the protrusion 234 have a first included angle, which ensures that the second bending part 230 will produce a certain elastic deformation after unfolding, thereby enabling the second bending part 230 to have greater rebound force when switching from unfolded state to folded state, and further improving the support capacity of the second bending part 230 for the first bending part 110.

[0075] Specifically, in the length direction of the first bend 110, the connecting portion 232 extends in a straight line, that is, the second bend 230 is cut along the length direction of the first bend 110, and the cutting surface of the connecting portion 232 extends in a straight line.

[0076] In the length direction of the first bend 110, the protrusion 234 extends in a straight line or an arc, that is, the second bend 230 is cut along the length direction of the first bend 110, and the cutting surface of the protrusion 234 extends in a straight line or an arc.

[0077] Optionally, such as Figure 6 As shown, the thickness of the second bending portion 230 is 0.03 mm, and the bending area is processed into multiple parallel curved surfaces through sheet metal punching. The width W2 of the connecting portion 232 is greater than or equal to 0.7 mm and less than or equal to 1.5 mm. The radius R2 of the protrusion 234 is greater than or equal to 0.6 mm and less than or equal to 0.9 mm.

[0078] According to some embodiments of the present invention, such as Figure 6 As shown, the angle c of the first included angle is greater than 90 degrees.

[0079] In this embodiment, the angle c of the first included angle is greater than 90 degrees, so that the protrusion 234 extends outward relative to the connecting part 232, thereby enabling the protrusion 234 to move smoothly to a state parallel to the connecting part 232 during the folding process of the second bending part 230, thus making the folding process of the electronic device smoother.

[0080] Optionally, the angle c of the first included angle is less than 180 degrees.

[0081] Optionally, the angle c of the first included angle is greater than or equal to 130° and less than or equal to 150°.

[0082] Specifically, the angle c of the first included angle is 91 degrees.

[0083] The angle c of the first included angle is 130 degrees.

[0084] The angle c of the first included angle is 150 degrees.

[0085] The angle c of the first included angle is 179 degrees.

[0086] According to some embodiments of the present invention, such as Figure 5 As shown, in a cross-section of the second bend 230, the protrusion 234 and the connecting portion 232 extend in an arc.

[0087] In this embodiment, the protrusion 234 and the connecting portion 232 extend in an arc along the length direction of the first bending portion 110. When the electronic device switches from a folded state to an unfolded state, the second bending portion 230 has a stronger rebound capability, thereby improving the support capability of the second bending portion 230 for the first bending portion 110 and further reducing the creases when the electronic device is in the unfolded state.

[0088] Specifically, in the length direction of the first bend 110, the second bend 230 extends in an arc, that is, the second bend 230 is cut along the length direction of the first bend 110, and the cut surface of the second bend 230 extends in an arc.

[0089] According to some embodiments of the present invention, the thickness of the second bending portion 230 is less than the thickness of the first support portion 210; and / or the thickness of the second bending portion 230 is less than the thickness of the second support portion 220.

[0090] In this embodiment, the thickness of the second bending portion 230 is less than the thickness of the first support portion 210, and / or the thickness of the second bending portion 230 is less than the thickness of the second support portion 220. While ensuring that the second bending portion 230 has a certain support capacity, the thickness of the second bending portion 230 is reduced, thereby reducing the weight of the electronic device and facilitating the lightweight design of the electronic device.

[0091] According to some embodiments of the present invention, such as Figure 7 As shown, a second gap 214 exists between the first end of the protrusion 234 and the first support portion 210; and / or a third gap 224 exists between the second end of the protrusion 234 and the second support portion 220.

[0092] In this embodiment, a second gap 214 is provided between the first end of the protrusion 234 and the first support portion 210, which reduces the probability of the protrusion 234 scraping against the first support portion 210 during movement, and further improves the stability of the electronic device during unfolding and folding. In addition, the second gap 214 between the first end of the protrusion 234 and the first support portion 210 can prevent local stress concentration in the first support layer 200 from causing plastic deformation when processing the first support layer 200, thereby reducing the probability of the first support layer 200 breaking during processing.

[0093] A third gap 224 is provided between the second end of the protrusion 234 and the second support 220, which reduces the probability of the protrusion 234 scraping against the second support 220 during movement, and further improves the stability of the electronic device during unfolding and folding. In addition, the third gap 224 is provided between the first end of the protrusion 234 and the second support 220. When processing the first support layer 200, the third gap 224 can prevent local stress concentration in the first support layer 200 from causing plastic deformation, thereby reducing the probability of the first support layer 200 breaking during processing.

[0094] Optionally, the second gap 214 and the third gap 224 are grooves on both sides of the protrusion 234.

[0095] The first support layer 200 is a sheet metal part, which is formed in one step by stamping.

[0096] like Figure 7 As shown, the width of the second gap 214 is 0.5 mm, the length of the second gap 214 is 1.9 mm, the width W3 of the third gap 224 is 0.5 mm, and the length L of the third gap 224 is 1.9 mm, in order to prevent local stress concentration in the second bend 230 from causing plastic deformation.

[0097] According to some embodiments of the present invention, such as Figure 4 As shown, a fourth gap 238 is provided between the plurality of second bends 230 and the first bend 110.

[0098] In this embodiment, a fourth gap 238 is provided between the plurality of second bends 230 and the first bend 110, that is, a cavity is formed between the second bends 230 and the first bend 110. When the first support layer 200 and the display layer 100 are bonded together, the pressure on the first support layer 200 and the display layer 100 is reduced, thereby reducing the probability of the second bends 230 being transferred to the appearance of the electronic device through the adhesive layer and causing mold marks, thus improving the efficiency of the electronic device.

[0099] Optionally, the fourth adhesive layer 530 has a clearance at the location of the second bend 230, that is, the fourth adhesive layer 530 is not provided at the location of the second bend 230, thereby forming a cavity between the second bend 230 and the first bend 110.

[0100] Alternatively, the electronic device includes a mobile phone, tablet, smart wearable device, e-reader, or laptop.
