Detailed Description
As used herein, an "electronic device" (or simply "terminal") includes, but is not limited to, an apparatus that is 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 (e.g., 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 arranged to communicate over 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, satellite or cellular telephones; a Personal Communications System (PCS) terminal that may combine a cellular radiotelephone with data processing, facsimile and data communications capabilities; PDAs that may include radiotelephones, pagers, internet/intranet access, Web browsers, notepads, calendars, and/or Global Positioning System (GPS) receivers; and conventional laptop and/or palmtop receivers or other electronic devices that include a radiotelephone transceiver. A cellular phone is an electronic device equipped with a cellular communication module.
Referring to fig. 1, fig. 1 is a schematic structural diagram of some folding screen devices.
The inventor finds that the screen module 1 of most folding screen equipment adopts a planar design, and aims to solve the problem of uneven surface of a folding screen. However, the side of the screen module 1 adopting the planar design does not have a curved surface radian, so that the visual effect of observing the screen module 1 from the side is poor. Meanwhile, as shown in fig. 1, when the flat panel screen module 1 and the decoration ring 2 are assembled, the decoration ring 2 is buckled on the surface of the screen module 1 in order to improve the firmness of the screen module 1 and the structural strength of the equipment. Such a design mode can make the rosette 2 protruding on screen module 1, has increased the thickness of equipment, has still influenced the outward appearance expressive force of equipment. Therefore, in order to make the side visual effect of the screen module better and make the appearance of the device stronger, the side edge of the screen module 1 needs to be made into a curved surface shape.
Further, in order to satisfy the characteristic of being foldable, the adhesive used by the screen module 1 is generally an optical adhesive. The bending property and the adhesion property of the optical cement are two contradictory points, and when the bending property of the optical cement is good, the adhesion property is poor, and vice versa. Therefore, if the side of the panel module 1 is curved, the optical adhesive cannot satisfy the adhesion required for the curved area. Particularly, when the screen module 1 is folded, a corresponding tensile force is generated, so that the film layer peeling phenomenon is easily generated in the curved surface area of the screen module 1.
In order to solve the above problem, an embodiment of the application provides a display module for a foldable screen and an electronic device thereof. The present application will be described in further detail with reference to the following drawings and examples. It is to be noted that the following examples are only illustrative of the present application, and do not limit the scope of the present application. Likewise, the following examples are only some examples and not all examples of the present application, and all other examples obtained by a person of ordinary skill in the art without any inventive work are within the scope of the present application.

As shown in fig. 2 to 4, the electronic device 10 provided in the present embodiment may be a mobile phone, a tablet computer, a smart watch, and the like, and the following description is given by taking the mobile phone as an example in the present embodiment. The electronic device 10 includes: a display module 11 and a housing 12. The display module 11 is covered on the housing 12 to form an accommodating space. The accommodating space may be used for installing functional devices of the electronic device 10, such as a camera, a battery, a motherboard, and the like, so as to implement functional applications related to the electronic device 10.
The display module 11 can display images by using an OLED (Organic Light-Emitting Diode) screen, and the OLED screen can also satisfy the folding performance of the display module 11. Meanwhile, the display module 11 of the embodiment may be rectangular in shape, and may specifically be a hyperboloid screen, or may also be a single-curved screen. In some embodiments, the display module 11 may not be rectangular, which is not limited in the embodiments of the present application.
The housing 12 may include a decorative ring 121 and a rear cover 122, and one side of the decorative ring 121 is connected to the rear cover 122, for example, by bonding, welding, and inserting. The other side edge of the decoration ring 121 is disposed on the curved surface area of the display module 11 and is flush with the planar area of the display module 11 in the thickness direction. By the design mode, the decorative ring 121 does not protrude out of the plane area of the display module 11, the thickness of the electronic device 10 is reduced, and the appearance delicacy of the electronic device 10 is improved. In some embodiments, the bezel 121 and the rear cover 122 may also be a unitary structure to improve the structural strength of the housing 12, which is not limited in the embodiments of the present application.

As shown in fig. 5, the display module 11 includes: a main display area 111 and a curved display area 112 for displaying an electronic image desired by a user. Wherein the main display area 111 is foldable with respect to the axis 113. The curved display area 112 includes: the display device includes a first curved surface display area 112a and a second curved surface display area 112b, and the first curved surface display area 112a and the second curved surface display area 112b are respectively disposed on two sides of the main display area 111 parallel to the axis 113. For example, in this embodiment, the axis 113 is a symmetry line of the main display area 111, the main display area 111 can be symmetrically folded with respect to the axis 113, and the first curved display area 112a and the second curved display area 112b are also symmetrical with respect to the axis 113, so that the design manner not only enables the display module 11 to have a symmetrical aesthetic feeling, but also reduces the size of the display module 11 after being folded. In some embodiments, the display module 11 may also be configured as a single-sided curved surface, which only needs to ensure that the curved surface side of the display module 11 is parallel to the axis 113, and this embodiment does not limit this.
In some embodiments, the axis 113 may not only be longitudinally disposed as shown, such that the main display area 111 folds side-to-side based on the axis 113. It may also be placed laterally such that the main display area 111 folds up and down based on axis 113. Meanwhile, the axis 113 may also be a third line or a quarter line of the main display area 111, so that the main display area 111 is asymmetrically folded, and the position of the axis 113 may be set according to actual requirements.
The terms "first", "second" and "third" in this application are used for descriptive purposes only and are not to be construed as indicating or implying relative importance or implying any indication of the number of technical features indicated. Thus, a feature defined as "first," "second," or "third" may explicitly or implicitly include at least one of the feature.
Referring to fig. 6 to 9 in conjunction with fig. 4, the display module 11 includes: a support plate 114, an adhesive layer 115, a display film layer 116, a limiting plate 117, a mounting portion 118 and a driving chip 119. The supporting plate 114, the adhesive layer 115 and the display film layer 116 are sequentially stacked in the thickness direction of the display module 11. The stopper plate 117, the mounting portion 118, and the driving chip 119 are stacked in this order in a direction away from the supporting plate 114.
Specifically, the supporting plate 114 may be a metal plate having a certain structural strength and bending performance, and may not only support each film layer stacked on the display module 11, but also satisfy the foldability of the display module 11. For example, in the present embodiment, the supporting plate 114 may be a plate made of stainless steel.
The adhesive layer 115 is used to adhere the supporting plate 114 and the display film layer 116, and the adhesive layer 115 includes an optical glue 1151 and a structural glue 1152. The optical adhesive 1151 is disposed in the main display area 111, so that the supporting plate 114 and the display film layer 116 have a certain adhesive force in the main display area 111, and the folding performance required by the supporting plate 114 and the display film layer 116 in the main display area 111 can be satisfied. The structural adhesive 1152 is disposed on the first curved surface display area 112a and the second curved surface display area 112b, so that the supporting plate 114 and the display film layer 116 have stronger adhesive force and structural strength in the curved surface display area 112, and the problem that the supporting plate 114 and the display film layer 116 are peeled off in the curved surface display area 112 due to the influence of tensile force generated by folding the display module 11 based on the axis 113 or the elastic force of the display film layer 116 is avoided. The stability of the display module 11 in the curved display area 112 is improved. From this, display module assembly 11 can also make the side curved surface form when satisfying the foldability for the visual effect of display module assembly 11 side is better. For example, in this embodiment, the material of the optical glue 1151 may be polymethyl methacrylate or epoxy acrylate. The structural adhesive 1152 may specifically be Tesa61365 double-sided adhesive. The optical glue 1151 may completely cover the main display area 111, and the structural glue 1152 may also completely cover the first curved display area 112a and the second curved display area 112 b. Due to the design mode, the coverage area of the optical cement 1151 and the structural cement 1152 is increased, the adhesion of the optical cement 1151 and the structural cement 1152 is improved, and the adhesion reliability of the supporting plate 114 and the display film layer 116 is further improved. In some embodiments, when the display module 11 is a single-sided curved surface, the structural adhesive 1152 only covers a single-sided curved surface region, and the rest positions are covered by the optical adhesive 1151.
Further, the thickness of the optical glue 1151 and the structural glue 1152 may be 0.1mm to 0.25 mm. For example, in the present embodiment, the optical glue 1151 and the structural glue 1152 have a thickness of 0.1mm, which satisfies the adhesion, flexibility and peeling resistance required between the supporting plate 114 and the display film layer 116. In addition, there is a gap 110 at the interface of the optical glue 1151 and the structural glue 1152. The width of the gap 110 is 0.2mm to 0.6mm, and the gap 110 is disposed in the area near the junction of the main display area 111 and the curved display area 112, so as to prevent the structural adhesive 1152 from being excessively adhered to the main display area 111, thereby affecting the folding performance of the main display area 111. For example, in this embodiment, the specific width of the gap 110 may be 0.4mm to space the optical glue 1151 and the structural glue 1152, so as to avoid chemical reaction caused by mixing between the optical glue 1151 and the structural glue 1152, which affects the adhesion, flexibility, peeling resistance, and the like of the optical glue 1151 and the structural glue 1152. In some embodiments, the width of the gap 110 between the optical glue 1151 and the structural glue 1152 may be other values than 0.4mm, and it is only necessary to ensure that the optical glue 1151 and the structural glue 1152 are spaced apart, and the gap 110 does not affect the normal image display of the display module 11. The optical glue 1151 and the structural glue 1152 may have a thickness value other than 0.1mm, and the thickness value may be specifically set according to the actually required adhesiveness, bendability, peeling resistance, and thickness. The embodiments of the present application are not described in detail herein.
The display film layer 116 includes, stacked in the thickness direction: a back film 1161, a flexible display substrate 1162, a polarizer 1163 and a protection film 1164. The back film 1161 is disposed between the adhesive layer 115 and the flexible display substrate 1162, so that the flexible display substrate 1162 is not in direct contact with the adhesive layer 115, and the flexible display panel 1162 is protected from the adhesive in the adhesive layer 115. The flexible display substrate 1162 may be specifically an OLED screen to meet the folding performance of the display module 11. The polarizer 1163 is a circular polarizer and is used for preventing reflection in the main display area 111 of the display module 11, so as to prevent the display module 11 from reflecting and shining. The protective film 1164 may be a CPI (color Polyimide) film, which has heat resistance superior to other plastic materials such as polyethylene Terephthalate (PET), Polycarbonate (PC), etc., and is not fragile after being bent like glass, so that not only can the folding performance of the display module 11 be satisfied, but also the display module 11 can be protected from external interference.
The stopper plate 117 and the mounting portion 118 may be specifically a metal plate having a certain structural strength and bending property, and its specific material is the same as or similar to that of the support plate 114. In the present embodiment, the position-limiting plate 117 is disposed on the surface of the supporting plate 114 away from the adhesive layer 115, and a partial region of the position-limiting plate 117 is disposed in the curved display region 112. The mounting plate 118 is disposed on the surface of the limiting plate 117 away from the supporting plate 114. Wherein, the limiting plate 117 is bent by 180 degrees and overlapped with itself to increase the distance between the mounting plate 118 and the supporting plate 114. The perpendicular distance from the limiting plate 117 and the mounting plate 118 to the axis 113 is equal to or less than the perpendicular distance from the gap 110 to the axis 113, so that the limiting plate 117 and the mounting plate 118 are prevented from being too close to the main display area 111, and the folding performance of the main display area 111 is prevented from being affected. The driving chip 119 is disposed on the mounting plate 118, away from the limiting plate 117, and is configured to drive the flexible display substrate 1162 to work. The driving chip 119 may be specifically mounted near the gap 110, so as to avoid that the driving chip 119 is too close to the main display area 111, which affects the folding performance of the main display area 111. Further, the flexible display substrate 1162 extends towards the curved display area 112 away from the axis 113, and is bent to a surface of the mounting plate 118 away from the limiting plate 117, and is connected to the driving chip 119. The limiting plate 117 is bent by 180 degrees and overlapped to control the bending radius of the flexible display substrate 1162, so that damage caused by excessive bending of the flexible display substrate 1162 is avoided. In the embodiment, the bending radius of the flexible display substrate 1162 to the driving chip 119 is 0.35mm, so as to ensure the normal connection between the flexible display substrate 1162 and the driving chip 119. In some embodiments, the limiting plate 117, the mounting plate 118 and the driving chip 119 may not be limited by the gap 110, and only the limiting plate 117, the mounting plate 118 and the driving chip 119 need to be ensured not to affect the bending property of the display module 11. The mounting positions of the stopper plate 117, the mounting plate 118, and the driver chip 119 may be not only the second curved display region 112b shown in the drawings but also the first curved display region 112a, which is not limited in the embodiment of the present invention.
In the description of the present application, "plurality" means at least two, e.g., two, three, etc., unless explicitly specifically limited otherwise. All directional indications (such as up, down, left, right, front, and rear … …) in the embodiments of the present application are only used to explain the relative positional relationship between the components, the movement, and the like in a specific posture (as shown in the drawings), and if the specific posture is changed, the directional indication is changed accordingly.
Referring to fig. 10 to 12, fig. 10 is a schematic view of another cross-sectional structure of the display module 11 of fig. 5 along vi-vi, fig. 11 is a schematic view of another cross-sectional structure of the display module 11 of fig. 5 along vi-vi, and fig. 12 is a schematic view of another cross-sectional structure of the display module 11 of fig. 5 along vi-vi.
As shown in fig. 10-12, in some embodiments, the structural adhesive 1152 may not completely cover the curved display area 112. For example, the structural adhesive 1152 may cover only four corners of the display module 11, or the structural adhesive 1152 may be distributed in a segmented manner in the curved display area 112. The remaining locations of the curved display area 112 are covered by optical glue 1151. It is only necessary to ensure that the supporting plate 114 and the display film layer 116 have sufficient peel resistance in the curved display area 112. On the premise that the structural adhesive 1152 can satisfy the adhesiveness and peel resistance required by the display module 11 in the curved display area 112, the structural adhesive 1152 is reduced, and the influence of the structural adhesive 1152 on the foldability of the display module 11 can be weakened. The specific position and distribution mode of the structural adhesive 1152 can be specifically set according to the actual required bonding strength. In addition, in some embodiments, the shape of the structural adhesive 1152 may be square, rectangular, or circular. The embodiments of the present application do not limit this.
The terms "comprising" and "having," as well as any variations thereof, in this application are intended to cover non-exclusive inclusions. For example, a process, method, system, article, or apparatus that comprises a list of steps or elements is not limited to only those steps or elements listed, but may alternatively include other steps or elements not listed, or inherent to such process, method, article, or apparatus.
The display module assembly 11 for the foldable screen and the electronic device 10 thereof provided by the embodiment of the application are configured by disposing the adhesive layer 115 between the supporting plate 114 and the display film layer 116. And the adhesive layer 115 includes: optical glue 1151 and structural glue 1152. The optical glue 1151 is disposed in the main display region 111, and the structural glue 1152 is disposed in the curved display region 112. Therefore, the optical glue 1151 and the structural glue 1152 can not only adhere to the supporting plate 114 and the display film 116, but also meet the folding performance of the main display area 111 and the peeling resistance of the curved surface display area 112, and avoid the supporting plate 114 and the display film 116 from peeling off due to insufficient adhesion of the curved surface display area 112. Meanwhile, the design of the curved surface display area 112 also enables the visual effect of observing the display module 11 from the side surface to be better, and improves the delicacy of the product appearance and the core competitiveness of the product. Further, the decoration ring 121 is disposed in the curved surface area of the display module 11, and is flush with the planar area of the display module 11 in the thickness direction. By the design mode, the decorative ring 121 does not protrude out of the plane area of the display module 11, the thickness of the electronic device 10 is reduced, and the appearance delicacy of the electronic device 10 is improved.
The above description is only a part of the embodiments of the present application, and not intended to limit the scope of the present application, and all equivalent devices or equivalent processes performed by the content of the present application and the attached drawings, or directly or indirectly applied to other related technical fields, are also included in the scope of the present application.
