Detailed Description
The application is described in further detail below with reference to the drawings and examples. It is specifically noted that the following examples are only for illustrating the present application, but do not limit the scope of the present application. Likewise, the following examples are only some, but not all, of the examples of the present application, and all other examples, which a person of ordinary skill in the art would obtain without making any inventive effort, are within the scope of the present application.
Reference herein to "an embodiment" means that a particular feature, structure, or characteristic described in connection with the embodiment may be included in at least one embodiment of the application. The appearances of such phrases in various places in the specification are not necessarily all referring to the same embodiment, nor are separate or alternative embodiments mutually exclusive of other embodiments. Those of skill in the art will explicitly and implicitly appreciate that the embodiments described herein may be combined with other embodiments.
As used herein, an "electronic device" (or simply "terminal") includes, but is not limited to, a device configured to receive/transmit communication signals via a wireline connection, such as via a public-switched telephone network (PSTN), a Digital Subscriber Line (DSL), a digital cable, a direct cable connection, and/or another data connection/network, and/or via a wireless interface, such as for example, for a cellular network, a Wireless Local Area Network (WLAN), a digital television network, such as a DVB-H network, a satellite network, an AM-FM broadcast transmitter, and/or another communication terminal. A communication terminal configured to communicate through a wireless interface may be referred to as a "wireless communication terminal", "wireless terminal", or "mobile terminal". Examples of mobile terminals include, but are not limited to, satellites or cellular telephones; a Personal Communications System (PCS) terminal that may combine a cellular radiotelephone with data processing, facsimile and data communications capabilities; a PDA that can include a radiotelephone, pager, internet/intranet access, web browser, organizer, calendar, and/or a Global Positioning System (GPS) receiver; and conventional laptop and/or palmtop receivers or other electronic devices that include a radiotelephone transceiver. The mobile phone is the electronic equipment provided with the cellular communication module.
It should be noted that, the electronic device in the embodiment of the present application is mainly directed to an electronic device having a folding screen, for example, a folding screen mobile phone. In particular, the folding screen mobile phone has gradually become the development trend of the whole machine in the future, and has the advantages of entertainment and office, portability and capability of meeting the requirements of consumers on portability and various and unified functions. The folding screen mobile phone generally has folding modes such as inward folding, outward folding and the like. For the folding screen mobile phone in the inward folding mode, after the folding is completed, the display surfaces of the flexible screen are close to each other along the folding area, namely the flexible screen is in the inward folding mode. For the folding screen mobile phone in the outward folding mode, after the folding is completed, the display surfaces of the flexible screen deviate from each other along the folding area, namely the flexible screen is in a folding mode of being folded outwards.
However, in the research of the applicant, for the folding screen mobile phone, the non-display surface of the folding screen is attached to the mobile phone shell, and when the mobile phone is folded and used for a plurality of times, the edge of the folding screen is easy to wear, tilt, fall and damage.
In order to solve the problems, the technical scheme provided by the embodiment of the application has the thought that the edge of the folding screen is protected by arranging the decorating part on the edge of the folding screen, so that the defects of abrasion, tilting, falling damage and the like of the edge of the folding screen are prevented.
Referring to fig. 1 and 2, fig. 1 is a schematic structural diagram of an electronic device 100 according to some embodiments of the present application, and fig. 2 is a schematic structural exploded view of the electronic device 100 according to the embodiment of fig. 1, where the electronic device 100 may include a flexible screen 10, a decoration 20, and a middle frame 30. The electronic device 100 in the embodiment of the present application may be a portable device such as a mobile phone, a notebook computer, a tablet computer, a wearable device, etc. The present application is illustrated by way of example with respect to electronic device 100 as a cell phone.
It should be noted that, in the embodiments of the present application, all directional indicators (such as up, down, left, right, front, and rear … …) are merely used to explain the relative positional relationship, movement conditions, and the like between the components in a specific gesture (as shown in the drawings), and if the specific gesture changes, the directional indicators correspondingly change.
The direction indicated by the arrow X in fig. 1 may be simply regarded as the long axis direction of the electronic device, the direction indicated by the arrow Y in fig. 1 may be simply regarded as the short axis direction of the electronic device, and the direction indicated by the arrow Z in fig. 1 may be simply regarded as the thickness direction of the electronic device. Generally, the electronic device has a larger dimension in the long axis direction than in the short axis direction.
Further, the flexible screen 10 is configured to be foldable about the folding line 101 under the driving of the middle frame 30. The middle frame 30 may have a structure such as a rotation shaft structure or a hinge structure, so that the middle frame 30 may be folded in the long axis direction, that is, the electronic device 100 may be configured to be folded in the long axis direction. For example, the middle frame 30 may be divided into two frames located at both sides of the folding line 101, which may be connected to a rotation shaft structure or a hinge structure, etc., respectively, and folded along the folding line 101 by the rotation shaft structure or the hinge structure, etc. The flexible screen 10 may be connected to the middle frame 30 by one or a combination of snap-fit, glue, weld, etc. assembly such that the flexible screen 10 and the middle frame 30 may be folded together along the fold line 101.
It will be appreciated that to avoid creasing of the flexible screen 10, the area of the flexible screen 10 corresponding to the fold line 101 is generally folded into a bent shape when the flexible screen 10 is folded. Based on the fold line 101 of the flexible screen 10, the flexible screen 10 has a folded region 102 and an unfolded region 103, the folded region 102 being foldable when the flexible screen 10 is folded, the unfolded region 103 remaining generally flat. Wherein the folded region 102 and the unfolded region 103 constitute an integrated flexible screen 10 and are used for displaying pictures. The folding area 102 may have a symmetrical structure with respect to the folding line 101, that is, parameters such as a size, a shape, etc. of the folding area 102 at both sides of the folding line 101 may be the same or similar. The non-folding region 103 is connected to the side edge of the folding region 102, that is, the non-folding region 103 is connected to the edge of the folding region 102 which is disposed opposite to the folding line 101 in the longitudinal direction. Alternatively, the non-folded region 103 may have a symmetrical structure with respect to the folded region 102, that is, the non-folded region 103 is disposed opposite to each other in the long axis direction, and the two portions located on both sides of the folded region 102 may have the same or similar size, shape, and other parameters.
Referring to fig. 3 in combination, fig. 3 is a schematic cross-sectional structure of the area a of the electronic device 100 in the embodiment of fig. 1, where the plane of the cross-section may be parallel to the XZ plane.
The center 30 is configured to carry the flexible screen 10 and/or trim 20, the trim 20 having a portion that wraps around the periphery of the edge of the flexible screen 10. It can be appreciated that the decoration 20 surrounds at least part of the periphery of the flexible screen 10, so as to protect the periphery of the flexible screen 10 and avoid the defects of abrasion, tilting, falling damage and the like of the periphery of the flexible screen 10.
However, based on the setting of the decoration 20, the frame of the electronic device 100 is wider, and the decoration 20 generally protrudes out of the edge of the flexible screen 10, which affects the overall display effect of the electronic device 100 and makes the user experience feel less good to some extent.
As shown in fig. 3, the middle frame 30 may include a middle plate 31 and a rim 32 extending from an edge of the middle plate 31. The middle plate 31 may be configured to carry the flexible screen 10 and the bezel 32 may be configured to carry the trim piece 20.
Based on this, the bezel of the electronic device 100 is mainly defined by the a-E dimensions shown in fig. 3.
The dimension a may be a border of the flexible screen 10, that is, a dimension of a distance between an edge of a display area of the flexible screen 10 and an edge of a contour of the flexible screen 10. This dimension is related to the dimension of the flexible screen 10 itself, i.e., the a dimension is not within the scope of the improved embodiment of the present application and therefore can be understood as a constant value.
The B dimension may be a design relief dimension between the flexible screen 10 and the center frame 30 (e.g., bezel 32) that is comprised of a fit tolerance between the flexible screen 10 and the center frame 30, a laminate dislocation when the flexible screen 10 is folded, and a bouncing of the flexible screen 10 relative to the center frame 30 when dropped.
Referring to fig. 4 in combination, fig. 4 is a schematic view of a stacked and staggered structure of the flexible screen 10 when the flexible screen 10 is folded, and the flexible screen 10 may include a substrate 110, a display layer 120, a polarizer 130, an ultra-thin glass 140, and a protective layer 150, which are stacked in order. The flexible screen 10 is prone to misalignment between the laminates when folded, which may range from 0.1mm to 0.4mm.
Referring to fig. 5 in combination, fig. 5 is a schematic structural diagram of the flexible screen 10 and the middle frame 30 according to some embodiments of the present application, when the electronic device 100 falls, the flexible screen 10 and the middle frame 30 are connected by bonding, and a bouncing phenomenon may occur during a falling impact, and the bouncing range is generally 0.2-0.4mm.
Based on this, in further combination, the fit tolerance between flexible screen 10 and bezel 30 is typically + -0.2 mm, and the B dimension may typically be in the range of 0.5-1.0mm.
The C-dimension may be a width of overlap support between the trim piece 20 and the middle frame 30 (e.g., the frame 32) to prevent the trim piece 20 from coming off the couch or even pinching the flexible screen 10. The general design range of the dimension C may be 0.3-0.8mm, so that the middle frame 30 has a better supporting effect on the decoration 20, and avoids deformation of the decoration 20.
The D dimension may be the width of the spot size of the decorative piece 20 adhered to the center 30. The general design range of the dimension D may be 0.5-1.0mm, so that a better adhesion effect is achieved between the decoration 20 and the middle frame 30, and a dislocation phenomenon of the decoration 20 is avoided.
The E size may be the overlap width between the decoration 20 and the outer side of the middle frame 30, so as to avoid the phenomenon of glue dispensing exposure, and influence the overall appearance of the product. The E size is generally designed to be 0.1-0.4mm, so as to cover the gap between the decoration piece 20 and the outer side of the middle frame 30 and avoid the outside of the glue body.
In summary, the dimensions of the bezel of the electronic device 100 (i.e., B+C+D+E) may be 1.4-3.2mm, excluding the size A of the bezel of the flexible screen 10 itself.
Referring again to fig. 3, in the display direction of the flexible screen 10, the decoration 20 is provided protruding from the flexible screen 10. I.e. the decorative piece 20 covers and protrudes beyond the edge of the flexible screen 10 to protect the edge of the flexible screen 10. In addition, the decoration 20 covers and protrudes out of the edge of the flexible screen 10, can play a sealing role on the gap between the flexible screen 10 and the middle frame 30, and can prevent foreign matters, water vapor and the like from entering the gap between the flexible screen 10 and the middle frame 30, and further can prevent the foreign matters from entering the gap to squeeze and damage the flexible screen 10. The height of the ornamental piece 20 protruding from the flexible screen 10 is generally 0.3-0.8mm. However, the arrangement of the structure of the decoration 20 protruding from the flexible screen 10 may affect the feel of use to some extent when the electronic device 100 is actually used.
Referring to fig. 6, fig. 6 is a schematic structural diagram of an electronic device 300 according to another embodiment of the present application, where the electronic device 300 may include a flexible screen 10, a middle frame 30, and a decoration 50. The electronic device 300 in the embodiment of the present application is different from the electronic device 100 in the foregoing embodiment in that: the decoration 50 is structured and arranged differently from the decoration 20, so that the frame of the electronic device 300 is narrower than the frame of the electronic device 100. It should be noted that the terms "first," "second," and the like herein are used for descriptive purposes only and are not to be construed as indicating or implying relative importance or implicitly indicating the number of technical features indicated. Thus, a feature defining "first," "second," etc. can include at least one such feature, either explicitly or implicitly.
The flexible screen 10 and the decoration 50 may form a folding screen assembly of the electronic device, so as to be capable of being folded synchronously with the middle frame 30 under the driving of the middle frame 30.
Alternatively, the flexible screen 10 has a folded region 102 and an unfolded region 103 of unitary construction, the unfolded region 103 being attached to the side edges of the folded region, see in particular the previous embodiments.
Alternatively, the trim piece 50 may include a carrier portion 51 and a trim portion 52 extending from an edge of the carrier portion 51, the carrier portion 51 being configured to carry the non-folded region 103 of the flexible screen 10. The ornamental portion 52 surrounds the periphery of the edge of the flexible screen 10. Preferably, the decorative portion 52 surrounds the periphery of the non-folded region 103 of the flexible screen 10. In other words, one side of the non-folded region 103 of the flexible screen 10 is integrally connected with the folded region 102, and the periphery of the non-folded region 103, to which the folded region 102 is not connected, is surrounded by the ornamental portion 52. Wherein the carrying portion 51 and the ornamental portion 52 may be divided into two portions which are located on both sides of the folding region 102 in the above-described long axis direction, i.e., the position of the ornamental portion 50 corresponding to the folding region 102 is broken to facilitate folding.
The non-folded area 103 of the flexible screen 10 may be connected to the carrier portion 51 of the decoration 50 by one or a combination of fastening, gluing, welding, and the like.
Further, the middle frame 30 is configured to carry the decoration 50, i.e. the middle frame 30 may be connected to the decoration 50 by one or a combination of assembly methods such as clamping, gluing, welding, etc.
Referring to fig. 7 in combination, fig. 7 is a schematic diagram of a partial cross-sectional structure of the electronic device 300 in the embodiment of fig. 6. The gap 104 is provided between the decorative portion 52 and the flexible screen 10, and the gap 104 is set with reference to the fit tolerance between the flexible screen 10 and the decorative portion 50 and the lamination misalignment when the flexible screen 10 is folded. Further, the buffer member 60 is disposed in the gap 104, and the buffer member 60 is filled in the gap 104, so that the edge of the flexible screen 10 of the decorative portion 52 can be shielded to present a better appearance, and external foreign matters, water vapor and the like can be prevented from entering the gap 104.
The buffer member 60 is made of a soft material, so as to provide a certain buffer space for the flexible screen 10 to fold and move, and further protect the edge of the flexible screen 10 to a certain extent. For example, as shown in FIG. 7, the cushioning member 60 may be made of a low density foam, which may have a density of 0.1-0.7g/cm 3.
Referring to fig. 8, fig. 8 is a schematic diagram illustrating a partial cross-sectional structure of an electronic device 300 according to other embodiments of the application. The embodiment of fig. 8 differs from the embodiment of fig. 7 in that: the material of the buffer 60 is different. In the embodiment of fig. 8, the material of the buffer 60 may be a low-modulus silicone adhesive, that is, the silicone adhesive may be filled into the gap 104 by way of glue filling to form the buffer 60.
Of course, in other embodiments, the material of the buffer member 60 may be foam, silica gel, glass cement, rubber or other flexible buffer materials that can fill the gaps 104, not easily crush and damage the side edges of the flexible screen 10, and can absorb the laminated dislocation of the flexible screen 10 during folding. Of course, it will be appreciated that the material of the bumper 60 may be one or more of a blend, without limitation.
In one embodiment, a first connector 71 for connecting the flexible screen 10 and the decoration 50 is provided between the flexible screen 10 and the decoration 50, and a second connector 72 for connecting the decoration 50 and the middle frame 30 is provided between the decoration 50 and the middle frame 30. Preferably, the second connecting member 72 is disposed between the bearing portion 51 and the middle frame 30 and is used for connecting the bearing portion 51 and the middle frame 30. For example, the first connecting member 71 may be a first adhesive 71, and the second connecting member 72 may be a second adhesive 72. Of course, the first connecting member 71 and the second connecting member 72 may be other structural members capable of performing a connecting function, which is not limited in the embodiment of the present application.
The second connecting member 72 has a first connecting surface 721 connected to the carrying portion 51 and a second connecting surface 722 connected to the middle frame 30, and the first connecting surface 721 and the second connecting surface 722 can relatively move in a staggered manner. That is, when dropped, the ornamental piece 50 and the center 30 can be relatively moved to absorb the destructive energy generated when dropped.
In one embodiment, the flexible screen 10 and the trim 50 are adhesively connected by a first gel 71 having a first modulus of elasticity, and the trim 50 and the center 30 are adhesively connected by a second gel 72 having a second modulus of elasticity. Preferably, the non-folded region 103 of the flexible screen 10 is adhesively attached to the carrier portion 51 of the trim piece 50 by the first glue 71.
Wherein the first elastic modulus of the first gel 71 is not less than the second elastic modulus of the second gel 72. Namely, the flexible screen 10 and the decoration 50 are bonded by using colloid with higher elastic modulus, so that the relative bouncing between the flexible screen 10 and the decoration 50 can be reduced or avoided when the flexible screen falls; the lower modulus glue bond between the trim piece 50 and the center 30 allows for relative movement between the trim piece 50 and the center 30 during a drop and absorbs the destructive energy generated during a drop.
Optionally, the flexible screen 10 and the decoration 50 are bonded by using a first colloid 71 with a normal temperature elastic modulus, that is, a first elastic modulus not smaller than 10MPa, where the thickness of the first colloid 71 may be 0.1-0.5mm, so as to ensure the bonding stability between the flexible screen 10 and the decoration 50, and make the flexible screen 10 and the decoration 50 not easy to relatively move when falling, so that the edge of the flexible screen 10 is damaged due to collision.
Optionally, the decoration piece 50 and the middle frame 30 are bonded by using a second glue 72 with a normal temperature elastic modulus, that is, a second elastic modulus not greater than 3MPa, and the thickness of the second glue 72 may be 0.1-0.5mm, so that the decoration piece 50 can perform bouncing relative to the middle frame 30 when falling, and further absorb the damage energy generated when falling.
The bonding shape of the first colloid 71 and the second colloid 72 may be a strip shape, an annular shape, a regional shape or other shapes, which is not particularly limited in the embodiment of the present application, and a person skilled in the art may flexibly adjust the bonding shape according to actual needs, so that stable bonding can be ensured.
Referring again to fig. 6, the carrier portion 51 of the trim piece 50 is provided with a relief area 510, the relief area 510 being configured to relieve structural members on a side of the flexible screen 10 adjacent to the carrier portion 51. Specifically, the non-display surface side of the flexible screen 10 is generally provided with structural members such as a flexible circuit board, a hard circuit board, an electronic component, a display chip, an auxiliary support or a filling material, and the flatness of the flexible screen 10 is ensured by providing the avoiding area 510 on the bearing portion 51 to avoid the structural members when the flexible screen 10 and the bearing portion 51 are adhered.
Referring to fig. 9, fig. 9 is a schematic diagram illustrating a partial cross-sectional structure of an electronic device 300 according to other embodiments of the application. The embodiment of fig. 9 differs from the embodiment of fig. 8 in that: the folding screen assembly further comprises a protective layer 80 arranged in correspondence of the gap 104, i.e. the buffer 60 is provided with a protective layer 80. Specifically, when the buffer 60 is provided in the gap 104, friction or abrasion is easily generated during use because the buffer 60 is exposed to the outside of the electronic apparatus 300. Based on this, the protective layer 80 may be formed on the surface of the buffer member 60 by spraying, dispensing, or the like, to protect the buffer member 60 from friction or abrasion during use. The material of the protective layer 80 may be UV glue or hot melt glue with higher hardness to ensure scratch resistance; in other words, the material elastic modulus of the protective layer 80 is not less than the material elastic modulus of the cushioning member 60.
According to the electronic equipment and the folding screen assembly thereof, the decorating part is arranged into the bearing part and the decorating part which are of the integrated structures, the bearing part is used for bearing the flexible screen, the decorating part surrounds the periphery of the edge of the flexible screen and is provided with the gap with the flexible screen, and the buffer part is arranged in the gap, so that the frame width of the electronic equipment in the related technology can be reduced, and the technical effect of a narrow frame is realized. Meanwhile, the gap between the flexible screen and the decorative part can provide space for the dislocation of the flexible screen when the flexible screen is folded, and the buffer part is arranged inside the gap, so that the gap can be filled, and the gap is avoided from being formed by external foreign matters or water vapor and the like. To further illustrate the magnitude of the bezel width reduction for the electronic device, further examples are provided below in connection with fig. 6 and 7.
Wherein the bezel of the electronic device 300 is primarily defined by the a-c dimensions shown in fig. 7.
The a-dimension may be the size of the border of the flexible screen 10, i.e. the distance between the edge of the display area of the flexible screen 10 to the edge of the outline of the flexible screen 10. This dimension is related to the dimension of the flexible screen 10 itself, i.e. the a-dimension is understood to be comparable or identical to the dimension a in the previous embodiment.
The b dimension may be the dimension of the gap 104 between the flexible screen 10 and the decorative portion 52, which is comprised of the fit tolerances between the flexible screen 10 and the decorative portion 50, the laminate misalignment when the flexible screen 10 is folded. Wherein the fit tolerance between the flexible screen 10 and the trim 50 is typically + -0.2 mm.
When the electronic device 300 is folded along the long axis direction, the magnitude of the dislocation of the laminate of the flexible screen 10 on opposite sides in the long axis direction is generally larger than the magnitude of the dislocation of the laminate of the flexible screen 10 on opposite sides in the short axis direction. Based on this, there is a first interval b1 between the flexible screen 10 and the decorative portion 52 in the long axis direction, and a second interval b2 between the flexible screen 10 and the decorative portion 52 in the short axis direction. Specifically, the decoration portion 52 includes a first decoration portion 521 and a second decoration portion 522 connected by bending, the first decoration portion 521 being located on a side of the non-folding region 103 facing away from the folding region 102; the first decorative portion 521 and the flexible screen 10 have a first interval b1 therebetween, and the second decorative portion 522 and the flexible screen 10 have a second interval b2 therebetween.
As previously mentioned, flexible screen 10 is prone to misalignment between the layers when folded, which may range from 0.1 mm to 0.4mm. Based on this, the first interval b1 may be designed to be 0.3-0.8mm, and the second interval b2 may be designed to be 0.2-0.5mm.
The c-dimension may be the width of the decorative portion 52, i.e. the width of the decorative portion 52 in the direction of the decorative portion 52 away from the flexible screen 10. In other words, the dimension c may be a width of the decoration portion 52 exposed outside the electronic device 300, and may be flexibly set according to the structural strength required by the decoration portion 52 and the appearance requirement of the whole electronic device 300. Alternatively, the c-size may be designed to be 0.3-3mm.
The material of the decoration 50 may be polycarbonate, glass fiber, aluminum alloy, magnesium alloy, etc., and specifically may be flexibly selected according to different strength requirements. Of course, when the material strength of the ornamental member 50 is selected to be high, the width of the ornamental member 52 may be relatively narrow.
In summary, in the long axis direction of the electronic device 300, the dimensions (i.e. b1+c) of the frame except the frame dimension a of the flexible screen 10 itself may be 0.6-3.8mm; the dimensions of the bezel of the electronic device 300 (i.e., b2+c) may be 0.5-3.5mm in the short axis direction, except for the size a of the bezel of the flexible screen 10 itself. That is, the electronic device 300 may have a minimum of 0.6mm for the frame-removed flexible screen 10 itself in the long axis direction and a minimum of 0.5mm for the frame-removed flexible screen 10 itself in the short axis direction, which is a significant improvement over the minimum of 1.4mm for the frame-removed flexible screen 10 itself of the electronic device 100.
It should be understood that the above-mentioned minimum frame size of the electronic device 300 is merely illustrative, and the minimum frame size may be changed when the structural form of the electronic device 300 or the form of the decoration changes, and the above-mentioned embodiment illustrates the reduction of the frame size of the electronic device 300 compared with the frame size of the electronic device 100 by the above-mentioned structure according to the embodiment of the present application, but is not limited thereto.
