Description

Technical Field

[0001] The present application relates to the field of terminal technology, and in particular to an electronic device. Background Art

[0002] With the development of science and technology, the application of electronic devices such as mobile phones is becoming more and more popular. Current electronic devices have various screens. In the process of manufacturing, delivery, assembly and subsequent use of electronic devices, in order to prevent the screen from being scratched, scratched or broken, a protective film is generally attached to the screen surface.

[0003] However, during the use of electronic devices, the protective film attached to the screen surface often comes into contact with the user's hands, face, etc., and the grease on the user's hands, face, etc. usually rubs onto the protective film. For example, for an outward-folding electronic device, when grease intrudes into the edge of the protective film, the protective film may be displaced as the electronic device is bent, causing the grease to more easily enter the inside of the protective film from the edge of the protective film, causing some areas, such as the edge area of ​​the protective film, to peel off or warp.

[0004] Therefore, it is urgent to provide an electronic device to effectively prevent the protective film on the screen surface from peeling off or warping. Summary of the invention

[0005] The present application provides an electronic device, in which even if the edge of a protective film in the electronic device is invaded by grease, sweat, etc., the grease and sweat will not directly contact the adhesive layer in the protective film, and the erosion of the adhesive layer by grease, sweat, etc. can be reduced or avoided through the grooves at the edge of the non-display area of ​​the protective film and / or the first cover plate and the glue therein, and a sealing effect can be achieved through the glue, with very good performance.

[0158] Figure 2 The circuit board assembly 103 includes two electronic components 1032. Of course, the number of the electronic components 1032 is not limited to two, which depends on the actual application.

[0159] In applications, the main circuit board 1031 may include printed circuit boards (PCB), flexible printed circuits (FPC), etc.

[0160] It should be understood that the electronic components 1032 may include but are not limited to chips, resistors, capacitors, inductors, potentiometers, electron tubes, heat sinks, electromechanical components, connectors, semiconductor discretes, sensors, power supplies, switches, micro motors, electronic transformers, relays, subscriber identity module (SIM) card sockets, etc.

[0161] In practical applications, the rear shell 102 may include a back cover (not shown in the figure), a frame (not shown in the figure) and other structures.

[0162] The back cover may be disposed on a side of the display screen 100 away from the light-transmitting cover plate 105 , and may be stacked with the light-transmitting cover plate 105 and the display screen 100 .

[0163] The frame can be disposed between the back cover and the light-transmitting cover plate 105 and fixed on the back cover.

[0164] The light-transmitting cover plate 105 can be fixed on the frame.

[0165] In application, when the electronic device does not include the middle frame 13, the circuit board assembly 103, the battery 104, etc. can be fixed to the surface of the display screen 100 close to the back cover; or, the circuit board assembly 103, the battery 104, etc. can also be fixed to the inner surface of the back cover.

[0166] In some embodiments, a battery mounting slot (not shown in the figure) may be provided on the surface of the middle frame 13 facing the back cover, and the battery 104 may be installed in the battery mounting slot, depending on the actual application.

[0167] In addition, the mobile phone 02 may also include other structures such as a microphone, a speaker, and a camera.

[0168] Only the contents related to the invention point are introduced here, and the rest are not described in detail.

[0169] The protective film provided by the related art is described below.

[0170] Currently, electronic devices, such as mobile phones, are increasingly used, and display screens are one of the components of electronic devices. In order to prevent the display screen from being scratched, slashed or broken during the production, delivery, assembly and subsequent use of electronic devices, a protective film is generally attached to the surface of the display screen to protect the display screen.

[0171] In practical applications, the protective film generally includes a protective film layer and an adhesive layer, wherein the protective film layer is bonded to the surface of the display screen through the adhesive layer.

[0172] With the development of smart phones and touch display technology, users need to have direct contact with the display screens in electronic devices. Therefore, during use, the protective film often comes into contact with the user's hands, face, etc., especially for some users with oily skin. When the protective film comes into contact with the hands, face, etc. of such users, the edge of the protective film is more likely to rub against the grease in the hands, face, etc. of the user.

[0173] With the development of science and technology, foldable electronic devices have been widely studied and applied. For foldable electronic devices, such as outward-folding mobile phones, if grease invades the edge of the protective film and when the surface of the mobile phone is subjected to tensile stress and folded outward, the protective film is displaced in a specific direction during the dynamic bending process, and the grease is more likely to enter the interior of the protective film under capillary action. When the grease erodes the interior of the protective film, the grease can act as a solvent and react with the adhesive material in the protective film, for example, crosslinking, swelling, etc., which can easily cause problems such as peeling or warping of the protective film at the bending axis and edges of the mobile phone.

[0174] So, based on the above, it can be seen that for electronic devices, especially foldable electronic devices, grease can easily invade the edge of the protective film and then enter the inside of the protective film, causing problems such as peeling or warping of the protective film, thereby causing performance defects of the electronic equipment.

[0175] In order to solve the above problems, there are currently some solutions, for example, adding oleophobic groups or oleophobic materials to the adhesive layer material of the protective film to reduce / avoid the invasion of grease into the protective film. However, adding oleophobic groups or oleophobic materials may cause the adhesive force of the adhesive layer to decrease, which has no positive effect on the adhesive effect of the protective film.

[0176] However, the relevant technology cannot effectively reduce or prevent grease from entering the protective film of electronic equipment, and may also cause problems such as complex process and increased cost.

[0177] In view of this, the present application provides an electronic device, in which at least one groove is arranged in a protective film and / or a cover plate located in a non-display area, and at least one of all the grooves contains glue. At the same time, the membrane layer covers all surfaces of the adhesive layer. In this way, even if grease, sweat, etc. invade the edge of the protective film, the grease and sweat will not directly contact the adhesive layer in the protective film, and the erosion of the adhesive layer by grease and sweat can be reduced or avoided through the groove and the glue inside. In addition, the protective film and the cover plate can be well sealed by the glue, thereby ensuring good performance of the electronic device.

[0178] Combine the following Figures 3 to 44 , the electronic device 01 provided in the embodiment of the present application is introduced in detail.

[0179] like Figures 3 to 44 As shown, the electronic device 01 provided in the present application may include: a display panel 1, a cover plate 2 and a protective film 3, the display panel 1 includes adjacent display area AA and non-display area BM; the cover plate 2 is arranged on the display panel 1, and the cover plate 2 is located in the display area AA and non-display area BM; the protective film 3 is arranged on the cover plate 2.

[0180] The cover plate 2 located in the non-display area BM is a first cover plate 21 .

[0181] The protective film 3 includes a film layer 31 and an adhesive layer 32 . The film layer 31 covers all surfaces of the adhesive layer 32 . The adhesive layer 32 is used to bond the film layer 31 to the cover plate 2 , and the adhesive layer 32 is at least located in the display area AA.

[0182] Along the direction perpendicular to the cover plate 2, the film layer arranged in the non-display area BM and without reduced thickness is the first film layer 311. A groove c is arranged in the first film layer 311 and / or the first cover plate 21, and the number of the groove c is at least one; at least one of all the grooves c has an adhesive dotted in it, and the adhesive has chemical resistance and sealing properties.

[0183] The chemical resistance mentioned above refers to the property that the adhesive is not very sensitive to foreign matter such as grease and sweat, and will not easily undergo chemical reactions such as cross-linking reactions even if it comes into contact with grease, sweat, etc.

[0184] The above-mentioned sealing property means that the adhesive can seal the gap between the protective film 3 and the cover plate 2 , and reduce or avoid the occurrence of holes between the protective film 3 and the cover plate 2 .

[0185] In practical applications, there is no limitation on the specific content of adhesive in each groove. For example, each groove may be partially filled with adhesive; or each groove may be completely filled with adhesive.

[0186] There is no limitation on the specific type of the adhesive. For example, the adhesive may include one or more combinations of silicone, ultraviolet rays curing adhesive (UV adhesive), acrylic adhesive, etc.

[0187] To achieve better effects, further optionally, all the grooves have adhesive, and each groove is completely filled with adhesive.

[0188] There is no limitation on the specific material of the adhesive layer. For example, the material of the adhesive layer may be optically clear adhesive (OCA) or the like.

[0189] It should be noted that glue is first applied in the groove and then a membrane layer is formed. This glue has good sealing and chemical resistance, and can prevent grease, sweat, etc. from corroding the internal OCA glue.

[0190] It should be understood that in actual applications, the structure of the cover plate is a three-dimensional structure. However, for the sake of convenience, the embodiment of the present application can regard the cover plate as a two-dimensional structure. Therefore, the direction perpendicular to the cover plate in the present application is Figures 4 to 43The OY direction shown is parallel to the cover plate. Figures 4 to 43 OX direction shown.

[0191] In application, the protective film may include only a film layer and an adhesive layer; of course, the protective film may also include other film layers in addition to the film layer and the adhesive layer, which depends on the actual application.

[0192] There is no limitation on the specific material of the membrane layer. For example, the material of the membrane layer may be polyethylene terephthalate (PET), thermoplastic polyurethane (TPU), or the like.

[0193] It should be understood that the above-mentioned adhesive layer is at least located in the display area means: Figure 4 and Figure 6 As shown, the adhesive layer 32 may be located only in the display area AA; or Figure 5 , Figure 7 , Fig. 9 , Fig.12 , Fig.14 , Fig.16 , Fig.18 , Fig. 20 , Fig. 22 , Fig.24 , Fig.26 , Fig.28 , Fig.30 , Fig.32 , Figures 34 to 43 As shown, the adhesive layer 32 is located in the display area AA and a portion of the non-display area BM, which is not specifically limited here.

[0194] In applications, such as Figure 7 , Fig. 9 , Fig.12 , Fig.14 , Fig.16 , Fig.18 , Fig. 20 , Fig. 22 , Fig.24 , Fig.26 , Fig.28 , Fig.30 , Fig.32 , Figures 34 to 43 As shown, along the OY direction, the film layer arranged in the non-display area BM and not thinned is the first film layer 311; the film layer arranged in the non-display area BM, thinned in thickness, and overlapping with the adhesive layer 32 is the second film layer 312; the film layer arranged in the non-display area BM, thinned in thickness, and not overlapping with the adhesive layer 32 is the third film layer 313.

[0195] It should be noted that, along the OY direction, the film layer disposed in the display area, with a reduced thickness, and overlapping with the adhesive layer is the fourth film layer (not marked in the figure).

In this case, the number of grooves in the first diaphragm layer and the number of grooves in the first cover plate may be completely the same, partially the same, or completely different, depending on the actual application.

[0197] As another example, at least one groove may be provided in both the first diaphragm layer and the second diaphragm layer, and no groove may be provided in the first cover plate.

In this case, the number of grooves in the first diaphragm layer, the number of grooves in the first cover plate, and the number of grooves in the second diaphragm layer may be completely identical, partially identical, or completely different, which shall be subject to actual application.

[0198] As another example, at least one groove may be provided in both the first diaphragm layer and the third diaphragm layer, and no groove may be provided in the first cover plate.

[0200] In application, there is no specific limitation on the shape, thickness, width, etc. of the groove. For example, the shape of the cross section of the groove along the direction perpendicular to the cover plate can be a rectangle, a regular trapezoid, an inverted trapezoid, etc.

[0201] Exemplarily, the thickness of the groove along the direction perpendicular to the cover plate may range from 20 μm to 40 μm. Specifically, the thickness of the groove along the direction perpendicular to the cover plate may be 20 μm, 30 μm or 40 μm.

[0202] Exemplarily, the width of the groove along the direction parallel to the cover plate ranges from 0.2 mm to 0.4 mm. Specifically, the width of the groove along the direction parallel to the cover plate may be 0.2 mm, 0.3 mm or 0.4 mm.

[0203] The specific preparation process of the above-mentioned groove is not limited. For example, the groove can be made by an etching process. Specifically, the groove can be made by a wet etching process.

[0204] In the application, there is no limitation on the specific type of the above-mentioned display panel. For example, the display panel can be a rigid display panel, such as a twisted nematic (TN type), vertical alignment (VA type), in-plane switching (IPS type), advanced superdimension switch (ADS type), and other types of liquid crystal display (LCD) display panels; or, the display panel can be a flexible display panel (i.e., bendable and foldable), such as an organic light-emitting diode (OLED) display panel, a mini light emitting diode (Mini LED) display panel, a micro light emitting diode (Micro LED) display panel, and the like.

[0205] It should be understood that the display panel including adjacent display area and non-display area means that the display panel includes a display area and a non-display area arranged around the display area.

[0206] The active area (AA) refers to an area used for display.

[0207] The non-display area BM refers to the area other than the AA area. The BM area is generally used to set drive wiring, drive circuits, etc. For example, a gate driver on array (GOA) circuit can be set; or an in-screen camera, receiver, speaker, etc. can be set.

[0208] As an example, Fig.44 As shown, the display panel may include a substrate 14 , and a middle frame 13 , a bonding layer 12 , and a light shielding layer 11 sequentially stacked on the substrate 14 .

[0209] The substrate 14 is located in the display area AA and the non-display area BM.

[0210] In applications, the substrate may be a rigid substrate, such as a glass substrate, etc.; or, the substrate may be a flexible substrate, such as a polyimide (PI) substrate, etc., which is not specifically limited here.

[0211] The light shielding layer 11 , the bonding layer 12 and the middle frame 13 are all located in the non-display area BM. The middle frame 13 is disposed on the substrate 14 . The bonding layer 12 is used to bond the middle frame 13 to the light shielding layer 11 .

[0212] In application, there is no limitation on the specific type of the light-shielding layer. For example, the light-shielding layer may be a black ink layer.

[0213] Of course, other properties of the above-mentioned film layers can be determined according to the display panel and will not be described in detail here.

[0214] like Figures 4 to 43 As shown, the electronic device may further include an AF coating 4, which is a surface coating that can effectively reduce the adhesion of fingerprints and various stains and is easy to clean.

[0215] The electronic device provided by the embodiment of the present application digs grooves at least in the first film layer and / or the first cover plate near the edge of the non-display area, and glue is dispensed in at least one groove. Since the film layer covers the entire surface of the adhesive layer, even if foreign matter, such as grease, sweat, etc., invades the edge of the protective film, the foreign matter will not directly contact the adhesive layer, and the erosion of the adhesive layer by the foreign matter can be reduced or avoided by the glue in the groove. Moreover, the protective film and the cover plate can be better sealed by the glue, thereby improving the performance of the electronic device.

[0216] Alternatively, as an implementable approach, such as Figure 3 , Figure 5 , Figures 7 to 43 As shown, the non-display area BM is arranged around the display area AA; each groove c located in the non-display area BM is arranged around the display area AA.

[0217] The adhesive layer 32 is located in the display area AA and a portion of the non-display area BM.

[0218] The film layer 31 covers all surfaces of the adhesive layer 32 and the upper surface of the first cover plate 21 .

[0219] Along the OY direction, the difference between the thickness h1 of the first film layer 311 and the thickness h2 of the second film layer 312 is equal to the thickness h3 of the adhesive layer 32 .

[0220] It should be understood that the second film layer is thinned relative to the first film layer, and the thinning height is the same as the thickness of the adhesive layer.

[0221] The electronic device provided in the embodiment of the present application has an adhesive layer that penetrates into the BM area of ​​the display panel and a light-shielding layer of black ink is coated under the cover plate, so that after subsequent glue is dispensed in the groove, the protective film will not affect the display effect of the electronic device.

[0222] Alternatively, as an implementable approach, such as Fig.15 and Fig.16 , Fig.29 and Fig.30 , Figure 31 to Figure 34 , Fig.36 and Fig.37 As shown, the number of the first grooves c1 is the same as the number of the second grooves c2, and each first groove c1 is connected to one second groove c2.

[0223] In the application, the width and height of the first groove and the second groove are not specifically limited. For example, Fig.15 and Fig.16 As shown, the orthographic projection E1 of the outer contour of the first groove c1 on the cover plate 2 is located within the orthographic projection E2 of the outer contour of the second groove c2 on the cover plate 2, that is, along the OX direction, the width d3 of the first groove c1 is smaller than the width d5 ​​of the second groove c2.

[0224] For example, Fig.15 and Fig.16 , Fig.29 and Fig.30 , Figure 31 to Figure 34 , Fig.37 As shown, along the OY direction, the height h4 of the first groove is greater than the height h6 of the second groove; or Fig.36 As shown, along the OY direction, the height h4 of the first groove is smaller than the height h6 of the second groove.

[0225] In applications, the shapes of all the first grooves may be the same; or, the shapes of all the first grooves may be partially the same; or, the shapes of all the first grooves may be different, which is not specifically limited here.

[0226] It should be noted that the shape of the second groove may refer to the shape of the first groove, which will not be described in detail here.

[0227] In applications, the shape of the first groove may be completely identical to that of the second groove; or, the shape of the first groove may be partially identical to that of the second groove; or, the shape of the first groove may be completely different from that of the second groove.

[0228] It should be understood that each of the above-mentioned first grooves is connected to a second groove, which may include: each of the first grooves is connected to a portion of a second groove; or each of the first grooves is connected to a second groove in its entirety; or each of the first grooves is connected to a portion of a second groove, which is not specifically limited here.

[0229] In application, there is no limitation on the specific heights of the first groove and the second groove along the OY direction. For example, the first groove may be arranged on the side of the diaphragm layer close to the cover plate and does not penetrate the diaphragm layer, and / or the second groove may be arranged on the side of the cover plate close to the diaphragm layer and does not penetrate the cover plate; alternatively, the first groove may be arranged on the side of the diaphragm layer close to the cover plate and does not penetrate the diaphragm layer, and / or the second groove may be arranged in the cover plate and penetrate the cover plate; alternatively, the first groove may be arranged in the diaphragm layer and penetrate the diaphragm layer, and / or the second groove may be arranged on the side of the cover plate close to the diaphragm layer and does not penetrate the cover plate.

[0230] The electronic device provided in the embodiment of the present application has grooves arranged in the first protective film and the first cover plate at the same time, and at least one groove has glue in it, and when the first groove is connected to the second groove, the glue in the first groove is also connected to the glue in the second groove, thereby, the bonding area of ​​the glue is larger, the bonding strength is stronger, the effect of resisting grease, sweat, etc. is better, and the sealing effect of the protective film and the cover plate is also better, thereby further improving the performance of the electronic device.

[0231] It should be noted that the number of the first groove and the second groove is not limited to the above. For example, the number of the first groove and the second groove may be different, for example, the number of the first groove is greater than the number of the second groove; or the number of the first groove is less than the number of the second groove, which is subject to actual application.

[0232] The positional relationship between the first groove and the second groove is not limited to the above. For example, the first groove and the second groove may be staggered and not connected, for example, the orthographic projection of the outer contour of each first groove on the cover plate is located within the gap between two adjacent second grooves; or, the orthographic projection of the outer contour of each second groove on the cover plate is located within the gap between two adjacent first grooves, which is subject to actual application.

[0233] The widths of the first groove and the second groove are not limited to the above. For example, the orthographic projection of the outer contour of the first groove on the cover plate may completely overlap with the orthographic projection of the outer contour of the second groove on the cover plate; or, the orthographic projection of the outer contour of the first groove on the cover plate may partially overlap with the orthographic projection of the outer contour of the second groove on the cover plate; or, the orthographic projection of the outer contour of the second groove on the cover plate may be within the orthographic projection of the outer contour of the first groove on the cover plate, which shall be subject to the actual application.

[0234] The heights of the first groove and the second groove are not limited to the above. For example, the height of the first groove in the direction perpendicular to the cover plate can be smaller than the height of the second groove in the direction perpendicular to the cover plate; or, the height of the first groove in the direction perpendicular to the cover plate can be smaller than the height of the second groove in the direction perpendicular to the cover plate, which is the same as the height of the first groove in the direction perpendicular to the cover plate. The specific heights are subject to actual application.

[0235] Alternatively, as an implementable approach, such as Fig.10 As shown, the electronic device 01 includes a first area z1, and among all the grooves, the adhesive content in the grooves located in the first area z1 is the largest.

[0236] In applications, the first area refers to a high-risk area in an electronic device that is easily corroded by foreign matter such as grease and sweat.

[0237] As an example, Fig.10 As shown, the first area z1 may be a rotation axis area z11.

[0238] As another example, Fig.10 As shown, the first area z1 may be an earpiece area z12.

[0239] In applications, the volume of the grooves in the first region may be set larger than the volumes of the grooves in other regions, so that the content of the adhesive in the grooves in the first region is maximized.

[0240] Exemplarily, the width of the groove in the first area along the direction parallel to the cover plate can be set to be greater than the width of the groove in other areas along the direction parallel to the cover plate; or, the height of the groove in the first area along the direction perpendicular to the cover plate can be set to be greater than the height of the groove in other areas along the direction perpendicular to the cover plate; or, the width of the groove in the first area along the direction parallel to the cover plate can be set to be greater than the width of the groove in other areas along the direction parallel to the cover plate, and the height of the groove in the first area along the direction perpendicular to the cover plate can be set to be greater than the height of the groove in other areas along the direction perpendicular to the cover plate, and no specific limitation is made here.

[0241] As an example, the width of the groove in the first area can be set as the first width, the width of the groove in the area other than the first area and the second area can be set as the second width, and the difference percentage between the second width and the first width can range from 10% to 30%. Specifically, the difference percentage between the second width and the first width can be 10%, 20% or 30%, etc.

[0242] like Fig.10 As shown, along the direction parallel to the cover plate, the width of the rotation axis area z11 is k1, the width of the first groove c1 is k2, and the width of the earpiece area z12 is k3, k1 is greater than k2, and k3 is greater than k2.

[0243] The electronic device provided in the embodiment of the present application further improves the protective effect of the protective film by increasing the amount of glue dispensed in the groove set in the first area, thereby further preventing erosion by grease, sweat, etc.

[0244] Alternatively, as an implementable approach, such as Fig.11 As shown, the electronic device includes a second area z2, and among all the grooves, the adhesive content in the grooves located in the second area z2 is the smallest.

[0245] In application, the second area refers to: a low-risk area in the electronic device that is not easily corroded by foreign matter such as grease and sweat and where the protective film is easy to tear off.

[0246] As an example, Fig.11 As shown, the second area z2 may be a corner area in the electronic device.

[0247] The corner area may refer to an area that is indented by about 4 mm to 6 mm from the edge of the electronic device toward the display area in a direction parallel to the cover plate. Specifically, the corner area may be an area that is indented by 4 mm, 5 mm, or 6 mm from the edge of the electronic device toward the display area.

[0248] The adhesive content in the grooves in the second region can be set as the first content, and the adhesive content in the grooves in other regions except the first region and the second region can be set as the second content, and the difference percentage between the second content and the first content can range from 30% to 50%. Specifically, the difference percentage between the second content and the first content can be 30%, 40% or 50%, etc.

[0249] In applications, the volume of the grooves in the second area can be set smaller than the volumes of the grooves in other areas, so that the content of the adhesive in the grooves in the second area is minimized.

[0250] Exemplarily, the width of the groove in the second area along the direction parallel to the cover plate can be set smaller than the width of the groove in other areas along the direction parallel to the cover plate; or, the height of the groove in the second area along the direction perpendicular to the cover plate can be set smaller than the height of the groove in other areas along the direction perpendicular to the cover plate; or, the width of the groove in the second area along the direction parallel to the cover plate can be set smaller than the width of the groove in other areas along the direction parallel to the cover plate, and the height of the groove in the second area along the direction perpendicular to the cover plate can be set smaller than the height of the groove in other areas along the direction perpendicular to the cover plate, and no specific limitation is made here.

[0251] The electronic device provided in the embodiment of the present application can reduce the adhesive force by reducing the amount of glue set in the groove of the second area, so as to facilitate tearing off the protective film when replacing the protective film and meet the requirements for tearing off the protective film.

[0252] Alternatively, as an implementable approach, such as Figure 6 and Figure 7 , Fig. 9 , Fig.12 , Fig.14 , Fig.16 , Fig.18 , Fig. 20 , Fig. 22 , Fig.24 , Fig.26 , Fig.28 , Fig.30 , Fig.32 , Figures 34 to 43 As shown, the adhesive layer 32 is retracted by a first distance d1 relative to the first film layer 311 along the direction close to the display area AA; along the OY direction, the film layer 31 that does not overlap with the adhesive layer 32 also includes a third film layer 313, and the first film layer 311 is connected to the second film layer 312 through the third film layer 313; the width of the third film layer 313 along the OX direction is the first distance d1; the height of the third film layer 313 along the OY direction is the same as the height of the second film layer 312 along the OY direction, both of which are h2.

[0253] In the application, the first distance is not specifically limited. For example, the value range of the first distance may include 0.07 mm-0.09 mm. Specifically, the first distance may be 0.07 mm, 0.08 mm or 0.09 mm.
