The composite panel 30 has a first surface facing the front side of the electronic device 1 and a second surface facing the opposite side of the first surface. It can be said that the second surface faces the inner side of the electronic device 1. The first surface and the second surface are also referred to as a front surface and a back surface, respectively, when viewed from the front surface side of the electronic device 1.

  As shown in FIG. 2, the composite panel 30 includes a glass panel 31 and a scratch-proof resin panel 32. The damage prevention resin panel 32 is joined to the glass panel 31 so as to be positioned on the first surface side with respect to the glass panel 31. The glass panel 31 is joined to the housing 10 at the end on the second surface side. The display unit 20 is bonded to the second surface side of the glass panel 31. An internal structure 60 is provided in a region surrounded by the housing 10 and the composite panel 30. The internal structure 60 may be, for example, a battery or a substrate including a processor or an electronic circuit that functions as a control unit that controls each component of the electronic device 1. The internal structure 60 may include the in-camera 50 or the illuminance sensor 51.

  The control unit of the electronic device 1 is configured as a processor, for example. The control unit may include one or more processors. The processor may include a general-purpose processor that reads a specific program and executes a specific function, and a dedicated processor specialized for a specific process. The dedicated processor may include an application specific integrated circuit (IC). The application specific IC is also called ASIC (Application Specific Integrated Circuit). The processor may include a programmable logic device. The programmable logic device is also called a PLD (Programmable Logic Device). The PLD may include an FPGA (Field-Programmable Gate Array). The control unit may be any of SoC (System-on-a-Chip) and SiP (System In a Package) in which one or a plurality of processors cooperate.

  The display unit 20 displays characters, images, operation objects, pointers, and the like based on information acquired from the control unit or the like of the electronic device 1. The display unit 20 may be a display device such as a liquid crystal display, an organic EL (Electroluminescence) display, or an inorganic EL display, but is not limited thereto.

  The glass panel 31 may include a touch sensor. The glass panel 31 provided with a touch sensor is also called a touch panel. The touch panel can detect a touch by a user as an input. The touch panel to which the display unit 20 is bonded is also referred to as a touch panel display.

  The in-camera 50 images a subject located on the front side of the electronic device 1. The in-camera 50 may include an image sensor. The in-camera 50 may include an optical system such as a lens. The illuminance sensor 51 detects the illuminance on the front side of the electronic device 1. The electronic device 1 may control the luminance of the image displayed on the display unit 20 according to the illuminance.

  As shown in FIG. 3, the housing 10 includes an outer peripheral portion 11 and a support portion 12. The outer peripheral part 11 is also called a rim. The housing 10 may be made of a material such as metal or resin, for example. The housing | casing 10 may be comprised with the material which compounded materials, such as a metal or resin. The housing 10 may be made of various other materials.

  The composite panel 30 is disposed inside the outer peripheral portion 11. The composite panel 30 is joined to the housing 10 such that the glass panel 31 is supported by the support portion 12 at the end on the second surface side. In this case, the scratch-proof resin panel 32 faces the front surface of the electronic device 1. The display unit 20 is bonded to the second surface side of the glass panel 31. That is, the display unit 20 is joined to the inside of the housing 10. It can be said that the display unit 20 is joined to the housing 10 via the composite panel 30.

  When the damage prevention resin panel 32 faces the front surface of the electronic device 1, the glass panel 31 is less likely to be damaged even when the electronic device 1 receives an impact. As a result, the glass panel 31 is hardly cracked. The scratch-proof resin panel 32 may have a window that allows incident light to pass through corresponding to the position of the in-camera 50 or the illuminance sensor 51.

  As shown in FIG. 4, the front panel 40 is detachably disposed on the front surface side of the electronic device 1 so as to cover an end portion on the first surface side of the glass panel 31. By doing in this way, the impact to the edge part of the glass panel 31 can be relieved. As a result, the glass panel 31 is hardly damaged. The front panel 40 is positioned so that the end of the scratch-resistant resin panel 32 is exposed. By doing in this way, the front panel 40 is located side by side with the damage prevention resin panel 32 in the front surface of the electronic device 1. Compared with the case where the front panel 40 is positioned so as to overlap the damage prevention resin panel 32, the thickness of the electronic device 1 can be reduced.

  The front panel 40 is joined to the housing 10 by a front panel joining portion 41. The front panel 40 may be configured to be detachable from the housing 10. The front panel joint portion 41 may be composed of a joining member such as a screw, for example. With the front panel 40 removed from the housing 10, a jig 33 (see FIG. 9) for peeling the scratch preventing resin panel 32 can be inserted into the interface where the glass panel 31 and the scratch preventing resin panel 32 are joined. May be configured. In other words, the electronic device 1 may be configured to be able to access the interface where the glass panel 31 and the damage preventing resin panel 32 are joined in a state where the front panel 40 is removed from the housing 10.

  As shown in FIG. 5, the scratch-proof resin panel 32 includes a surface portion 321 and a base material 322. The surface portion 321 is located on the front side of the electronic device 1 and is directly touched with a user's finger or the like. The surface portion 321 may be a material having a relatively high hardness. The surface portion 321 may be made of a material that is resistant to a touch such as a finger. The surface portion 321 may be made of a material that is not easily damaged by collision of an object or the like. The surface portion 321 may be made of a material that is difficult to penetrate the colliding object. The surface portion 321 may have a predetermined thickness. The predetermined thickness may be a thickness determined according to the material so that the colliding object is difficult to penetrate. The surface portion 321 may be, for example, an acrylic resin. The surface portion 321 is not limited to an acrylic resin, for example, and may be an organic resin.

  The scratch-proof resin panel 32 has a first adhesive material 323 between the surface portion 321 and the base material 322. The surface portion 321 and the base material 322 are joined by the first adhesive material 323. The first adhesive material 323 may be a material having a high bonding strength with respect to the surface portion 321. When the surface portion 321 is an acrylic resin, the first adhesive material 323 may be an acrylic adhesive material or the like. When the surface portion 321 is an organic resin, the first adhesive material 323 may be an organic adhesive material or the like.

  The scratch-proof resin panel 32 has a second adhesive material 324 on the second surface side of the base material 322. The damage prevention resin panel 32 is bonded to the glass surface 311 of the glass panel 31 by the second adhesive material 324. The glass surface 311 is a surface on the first surface side of the glass panel 31. The second adhesive material 324 may be a material having a high bonding strength with respect to the glass surface 311. The second adhesive material 324 may be a silicon-based adhesive material or the like.

  The base material 322 may be a material having high bonding strength with respect to both the first adhesive material 323 and the second adhesive material 324. When the first adhesive material 323 and the second adhesive material 324 are an acrylic adhesive material and a silicon adhesive material, respectively, the base material 322 may be made of, for example, PET (Polyethylene Terephthalate).

  The surface portion 321 has an antifouling layer 325 on the first surface side corresponding to the front surface side of the electronic device 1. The antifouling layer 325 makes it difficult for oil and fat components such as fingerprints due to a user's touch to adhere thereto. As a result, the composite panel 30 can be difficult to get dirty. The antifouling layer 325 may be a layer formed by various surface treatments such as fluorine coating.

  Since the composite panel 30 includes the scratch-resistant resin panel 32, the glass panel 31 is less likely to be scratched as compared to a panel made of only glass. As a result, the panel can be difficult to break. The composite panel 30 can be hardly contaminated by having the antifouling layer 325 on the front side of the electronic device 1. Unlike the panel formed only of glass, the composite panel 30 does not have a possibility that dirt will adhere to the glass surface 311 covered with the scratch-proof resin panel 32. The glass surface 311 may not be provided with an antifouling coat such as a fluorine coat. By bonding the scratch-resistant resin panel 32 directly to the glass surface 311, the bonding strength between the glass panel 31 and the scratch-resistant resin panel 32 can be increased.

  For example, in a device such as a smartphone provided with a panel made of only glass, an antifouling coat may be applied to the surface of the panel. A user may use a device by attaching a protective sheet to a panel provided with an antifouling coating. The antifouling coat is a process that makes it difficult for dust and the like to adhere. The adhesive strength of the protective sheet with respect to the panel to which the antifouling coating is applied can be lower than the adhesive strength with respect to the panel to which the antifouling coating is not applied.

  The adhesive strength can be measured as a force necessary for peeling two sheets adhered to each other at a constant speed. The glass panel 31 and the protective sheet can be regarded as a rigid material and a flexible material, respectively. When measuring the adhesive strength between the rigid material and the flexible material, the sheet may be peeled off by 180 degree peeling. 180 degree peeling is a method in which a flexible material is bent at an angle close to 180 degrees and peeled from a rigid material. According to the actual measurement results, the adhesive strength between the antifouling coated glass panel 31 and the protective sheet is 10 minutes of the adhesive strength between the glass panel 31 and the protective sheet that are not antifouling coated. 1 or less. That is, the antifouling coat reduces the adhesive strength of the protective sheet. The peeling method used for measuring the adhesive strength may be another form of peeling method such as T-type peeling.

  The protective sheet attached to the glass panel 31 with the antifouling coating may be easily peeled off when a nail or the like is caught on the end of the protective sheet when the electronic apparatus 1 is normally used. Further, the protective sheet attached to the glass panel 31 with the antifouling coating is easily peeled off due to a decrease in adhesive strength caused by oil or moisture entering the adhesive interface between the protective sheet and the glass panel 31. Sometimes. Moreover, the protective sheet affixed on the glass panel 31 to which the antifouling coating has been applied may be warped and deformed due to the influence of heat or humidity, and the adhesive strength may not be able to withstand the deformation and may be easily peeled off. On the other hand, the composite panel 30 according to the present embodiment joins the scratch-proof resin panel 32 to the glass surface 311 of the glass panel 31 on which the antifouling coating is not applied. By doing in this way, compared with the case where a user sticks a protection sheet, the damage prevention resin panel 32 becomes difficult to peel off.

  The damage prevention resin panel 32 makes the glass panel 31 difficult to be damaged. Although the glass panel 31 is not easily scratched, the scratch-resistant resin panel 32 may be scratched. The composite panel 30 is configured to be peelable while being configured so that the glass panel 31 and the scratch-resistant resin panel 32 are not easily peeled off. When the damage preventing resin panel 32 is configured to be peelable, when the damage preventing resin panel 32 is damaged, only the damage preventing resin panel 32 can be replaced. In this case, the glass panel 31 does not need to be replaced. As a result, repair can be facilitated.

  The glass panel 31 may have a curved shape in a region near the end of the housing 10. The scratch-resistant resin panel 32 joined to the glass panel 31 having a curved shape may be easily peeled off at an end portion where the curvature of curvature is increased. When the damage prevention resin panel 32 has relatively low flexibility, it is more easily peeled off from the curved glass panel 31. When the antifouling coat is applied to the glass panel 31, the scratch-resistant resin panel 32 is more easily peeled off from the glass panel 31. Even if it is a case where the damage prevention resin panel 32 has comparatively low flexibility by joining to the glass surface 311 of the glass panel 31 to which the antifouling coating is not applied, the damage prevention resin panel 32 is curved. It becomes difficult to peel off from the glass panel 31 which has a shape.

  The texture received by the user when touching a panel made of resin alone may be different from the texture received when touching a panel containing glass. The composite panel 30 according to the present embodiment can provide the texture received from the panel containing glass and can reduce the risk of occurrence of cracks in the panel containing glass.

  The second adhesive material 324 may be configured so that bubbles are less likely to remain at the joint when the scratch-resistant resin panel 32 is joined to the glass surface 311. For example, the second adhesive material 324 can be configured such that bubbles are easily removed from the joint portion by appropriately setting the ratio of the slightly adhesive component and the strong adhesive component.

  The glass panel 31 and the display unit 20 may be bonded with a photo-curing material that is cured by irradiation with UV (Ultra Violet) light or the like. When the glass panel 31 and the display unit 20 are bonded with a material that is cured by irradiation with UV light, the scratch-resistant resin panel 32 is bonded to the glass panel 31 after the glass panel 31 and the display unit 20 are bonded. May be. By doing in this way, the damage prevention resin panel 32 is not irradiated with UV light or the like. As a result, it is possible to prevent the damage prevention resin panel 32 from being deteriorated by irradiation with UV light or the like. Further, when the scratch-resistant resin panel 32 is an acrylic resin, the glass panel 31 and the display unit 20 are bonded by irradiation with UV light or the like in a state where the scratch-resistant resin panel 32 is bonded to the glass panel 31 first. If it tries to do so, the light of the wavelength of UV region will be absorbed by acrylic resin. As a result, the amount of light necessary for curing the photocuring material cannot be obtained. On the other hand, if the damage prevention resin panel 32 is joined to the glass panel 31 after the glass panel 31 and the display unit 20 are joined, such a situation can be prevented.

  As shown in FIG. 6, the glass panel 31 may have a chamfered portion 312 at the end of the glass surface 311. The chamfered portion 312 has a chamfered shape located at a ridge between the side surface of the glass panel 31 and the glass surface 311. The chamfered portion 312 is not limited to the C chamfered shape illustrated in FIG. 6, and may be another chamfered shape such as an R chamfered shape. When the glass panel 31 has the chamfered portion 312, the scratch-resistant resin panel 32 is joined to the inside of the chamfered portion 312. In other words, the end portion of the scratch-preventing resin panel 32 is located away from the chamfered portion 312 by a predetermined distance or more.

  As shown in FIG. 7, when the end portion of the scratch preventing resin panel 32 is located overlapping the chamfered portion 312, a part of the second adhesive material 324 of the scratch preventing resin panel 32 is exposed. When dust or the like adheres to the second adhesive material 324, the bonding strength at the interface between the glass panel 31 and the scratch-proof resin panel 32 can be reduced. Further, when dust or the like adheres to the second adhesive material 324, appearance quality can be deteriorated. The composite panel 30 according to this embodiment shown in FIG. 6 is more likely to maintain the bonding strength between the glass panel 31 and the scratch-proof resin panel 32 as compared with the configuration shown in FIG. Further, the composite panel 30 according to the present embodiment shown in FIG. 6 is more easily maintained in appearance quality as compared with the configuration shown in FIG.

  As shown in FIG. 8, the scratch-proof resin panel 32 may be superimposed on a position where the glass panel 31 is supported by the support portion 12. The position where the glass panel 31 is supported by the support portion 12 is also referred to as a fulcrum. In other words, the edge part of the damage prevention resin panel 32 may be located outside the outer peripheral part 11 of the housing 10 from the fulcrum. The glass panel 31 can receive a relatively large stress at the fulcrum. When the damage prevention resin panel 32 is superimposed on the fulcrum, the stress applied to the composite panel 30 at the fulcrum can be dispersed also in the damage prevention resin panel 32. As a result, the stress applied to the composite panel 30 at the fulcrum can be relaxed.

  The damage prevention resin panel 32 may be damaged depending on the usage state of the electronic device 1. Even if the damage prevention resin panel 32 is damaged, the glass panel 31 can be prevented from being broken by absorbing the impact by the damage prevention resin panel 32. The damage prevention resin panel 32 may be replaced when it is damaged. The damage prevention resin panel 32 can be replaced by being configured to be peelable from the glass panel 31.

  As shown in FIG. 9, the jig 33 is easily inserted into the joint between the glass panel 31 and the scratch-proof resin panel 32 in a state where the front panel 40 is removed. The damage preventing resin panel 32 can be peeled off by inserting the jig 33 into the joint between the glass panel 31 and the damage preventing resin panel 32. In other words, the composite panel 30 is configured to be accessible by the jig 33 to the joint between the glass panel 31 and the scratch-proof resin panel 32 in a state where the front panel 40 is removed.

  In the electronic device 1 according to another embodiment, the front panel 40 may cover the end portion of the scratch-proof resin panel 32 as shown in FIG. In other words, the joint between the glass panel 31 and the scratch-resistant resin panel 32 is not exposed in a state where the front panel 40 is attached. In a state where the front panel 40 is removed, the joint between the glass panel 31 and the scratch-proof resin panel 32 is exposed. By doing so, it is difficult for dust to adhere to or collide with objects at the end of the scratch-proof resin panel 32. As a result, the scratch-proof resin panel 32 becomes difficult to peel off from the glass panel 31 except when it is intentionally peeled off.
