[0003] [Patent Document 1] Japanese Patent Publication No. 2022-079985 Summary of the Invention [Problem to be solved by the invention]

[0004] The above-described electronic devices employ a lightweight and thin display panel, such as an OLED (organic light-emitting diode) panel, to reduce the overall thickness and weight of the device. Lightweight and thin display panels are prone to swaying, for example, during touch operations or when gripping the edge of the housing, and this swaying, particularly at the outer periphery, can be noticeable from the outside. In particular, when a bezel member is attached to the outer periphery of the display panel, there is a concern that gaps may form between the panel surface and the bezel member when the display panel moves.

[0005] One solution is to support the display panel by placing a cushioning material between the outer periphery of the display panel and the inner surface of the housing member. However, the inner surface of the housing member may not be uniformly flat due to factors such as the internal components and design. In this case, if a raised portion is formed in the cushioning material, this portion may push up the display panel, making it difficult to provide stable support.

[0006] The present invention has been made in consideration of the above-mentioned problems of the conventional technology, and has an object to provide an electronic device that can stably support a display panel. [Means for solving the problem]

[0007] An electronic device according to one embodiment of the present invention comprises a housing member and a display panel having a display surface and a back surface opposite the display surface supported by the inner surface of the housing member, wherein the edge of the housing member is provided with a first flat surface and a second flat surface arranged in a stepped pattern with a step between them and positioned opposite the back surface of the display panel, and further comprises a cushioning material attached to the first flat surface and the second flat surface across the step and supporting the back surface of the display panel with its surface, the cushioning material being provided on the surface of at least the portion across the step and having a slit formed along a second direction intersecting a first direction from the first flat surface to the second flat surface. [Effects of the Invention]

[0008] According to the above aspect of the present invention, the display panel can be stably supported. [Brief explanation of the drawings]

DETAILED DESCRIPTION OF THE INVENTION

[0010] DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Hereinafter, preferred embodiments of an electronic device according to the present invention will be described in detail with reference to the accompanying drawings.

[0011] 1 is a schematic plan view of an electronic device 10 according to one embodiment, viewed from above. As shown in FIG. 1, the electronic device 10 according to this embodiment is a clamshell-type notebook PC, and is configured such that a first housing 11 and a second housing 12 are connected by a hinge 14 so as to be rotatable relative to each other. In this embodiment, the electronic device 10 is a notebook PC, but the electronic device may be other than a notebook PC, such as a standalone display device, a tablet PC, a smartphone, or a portable game console.

[0012] The second housing 12 is a flat box-like body and is adjacent to the first housing 11. Inside the second housing 12, various electronic components such as a motherboard equipped with a CPU and the like, a battery device, memory, an antenna device, etc. are housed. A keyboard 16 and a touchpad 17 face the top surface 12a of the second housing 12. The second housing 12 may be equipped with a touch panel display on the top surface 12a, on which a software keyboard may be displayed.

[0013] The first housing 11 is a flat box. The first housing 11 is equipped with a display panel 18. Hereinafter, the first housing 11 and each component mounted thereon will be described with reference to the direction as seen by a user viewing a display surface 18a of the display panel 18, with the left-right direction referred to as the X1 and X2 directions, the up-down direction referred to as the Y1 and Y2 directions, and the depth direction (thickness direction) referred to as the Z1 and Z2 directions. The X1 and X2 directions may be collectively referred to as the X direction, and the Y1, Y2 directions and the Z1, Z2 directions may similarly be referred to as the Y direction and the Z direction.

[0014] The display surface 18a of the display panel 18 faces the Z1-side surface of the first housing 11. The first housing 11 has a housing member 20 that forms the Z2-side surface and a bezel member 22 that forms the outer periphery of the Z1-side surface. The top, bottom, left, and right side surfaces of the first housing 11 are formed by upright walls 23 that stand up from the four peripheral edges of the housing member 20. The bezel member 22 is a thin, frame-shaped plate that surrounds the outer periphery of the display surface 18a of the display panel 18. The hinge 14 is connected to the Y2-side edge of the first housing 11 and is covered with a rod-shaped hinge cover that extends in the X direction.

[0015] The display panel 18 is configured, for example, by an OLED panel. OLED panels are lightweight and thin. The display panel 18 has a back surface 18b, which faces the Z2 side and is opposite to the display surface 18a, supported by the inner surface 20a of the housing member 20.

[0016] Fig. 2 is a schematic side view of the housing member 20. Fig. 3A is a schematic plan view of the housing member 20 as seen from the inner surface 20a side. In Fig. 3A, the outline of the display panel 18 is indicated by a two-dot chain line. Fig. 3B is a diagram showing the housing member 20 shown in Fig. 3A with a member for supporting the display panel 18 installed thereon.

[0017] As shown in FIGS. 2 and 3A, the housing member 20 can have a rectangular plate portion 26, a frame-shaped frame portion 27, and an embedded plate portion 28 embedded in a part of the plate portion 26.

[0018] As shown in FIG. 2, the housing member 20 of this embodiment has a dome-shaped curved surface 20c that bulges smoothly from the outer edge toward the center. The curved surface 20c is formed by curving the plate portion 26 and the frame portion 27 so that the outer surface 20b bulges in a dome shape from the outer peripheral edge toward the center. The inner surface 20a is recessed in a dish-like shape toward the Z2 side by the curved surface 20c. Reference numeral 20c1 in FIG. 3A denotes an inclined surface formed along the peripheral edge of the plate portion 26 and inclined toward the Z2 side from the outer edge toward the center. The inclined surface 20c1 is part of the curved surface 20c.

[0019] The curved surface shape 20c also extends to an edge portion 20d of the housing member 20. The standing wall 23 constitutes a part of the edge portion 20d, and its height in the Z direction is substantially constant all around. The edge portion 20d is formed so as to bulge in the Z2 direction from the Z2-side end of the standing wall 23 toward the center of the housing member 20, thereby forming a part of the curved surface shape 20c. Therefore, as shown in FIG. 2, for example, the left and right edge portions 20d extending in the Y direction on both sides in the X direction are curved in an arch shape so as to gradually recess toward the Z2 side toward the center in the longitudinal direction (Y direction).

[0020] The plate portion 26 is a base plate of the housing member 20 and forms most of the housing member 20, including the central portion. The plate portion 26 is a carbon fiber reinforced resin plate (CFRP plate) formed by laminating multiple layers of prepreg, which is carbon resin impregnated with matrix resin (e.g., thermosetting resin or thermoplastic resin, such as epoxy resin). The plate portion 26 may be configured such that an intermediate material, such as foam, is sandwiched between the prepreg layers. The plate portion 26 forms substantially the entire outer surface 20b of the housing member 20. The plate portion 26 may be formed of a metal, such as aluminum or titanium, instead of carbon fiber reinforced resin. The plate portion 26 may be formed of the same or a different type of resin as the frame portion 27 or the embedded plate portion 28.

[0021] The frame portion 27 is joined to the outer peripheral edge of the plate portion 26. The frame portion 27 is formed by injection-molding a resin material onto the outer peripheral edge of the plate portion 26 and joining the resin material to the outer peripheral edge of the plate portion 26. The frame portion 27 is laminated on the inner surface of the outer peripheral edge of the plate portion 26, and the portion covering the outer peripheral end face of the plate portion 26 becomes the edge portion 20d. The frame portion 27 can be formed, for example, from PCCF (carbon fiber reinforced polycarbonate). The plate portion 26 formed from CFRP is light and strong, but has problems with workability in machining and shaping. Therefore, the housing member 20 has a frame portion 27 formed from a resin material around the plate portion 26, and various shapes such as the edge portion 20d and screw holes are formed in the frame portion 27.

[0022] The embedded plate portion 28 is formed so as to fill an opening formed in a part of the plate portion 26. The embedded plate portion 28 can be formed integrally with the frame portion 27 using the same resin material. The embedded plate portion 28 is connected to the frame portion 27 by, for example, two bridge portions 28a. The embedded plate portion 28 can be used to provide a logo, a small lamp, or the like on the outer surface 20b of the housing member 20. The logo displays the product name, manufacturer name, etc. of the electronic device 10 using a character string, a figure, a mark, or a combination of these. The lamp is formed, for example, by an LED and can display the operating status, etc. of the electronic device 10.

[0023] The curved surface 20c of the housing member 20 ensures a certain amount of space between the inner surface 20a and the rear surface 18b of the display panel 18. As shown in FIGS. 3A and 3B, the area near the center (bottom) of the curved surface 20c that is recessed furthest toward the Z2 side provides an installation space for the control board 30. The control board 30 is a board that controls the display on the display panel 18. The control board 30 is connected to a motherboard or the like on the second housing 12 side via an FPC (flexible printed circuit board).

[0024] 3 denotes a metal bracket for connecting the hinge 14 to the housing member 20. The brackets 32 are fixed to the edge 20d on the Y2 side of the inner surface 20a of the housing member 20, and are provided in pair, for example, on the left and right.

[0025] Next, the support structure for the display panel 18 will be described.

[0026] As shown in FIG. 3B , the display panel 18 can be supported on the housing member 20 via double-sided adhesive tape 34 attached to the inner surface 20a. The double-sided adhesive tape 34 can be, for example, stretch release tape, stretch double-sided tape, or lala tape. The double-sided adhesive tape 34 has a characteristic that allows it to be stretched and peeled by pulling a tab at one end. The double-sided adhesive tape 34 has a strip shape extending, for example, along the Y direction, and a pair of double-sided adhesive tapes 34 are provided on the left and right sides in the X direction. The double-sided adhesive tape 34 is fixed at a position offset toward the center from the end faces 18c on both sides of the X direction of the display panel 18 (see FIGS. 3A and 3B ). The left and right edge portions 20d of the inner surface 20a are formed with shaping or screw holes, etc., to fit along the inner wall of the standing wall 23. Therefore, the double-sided adhesive tape 34 is positioned to avoid these. Specifically, the double-sided adhesive tape 34 on the X1 side is positioned offset toward the X2 side from the X1-side edge portion 20d. Similarly, the double-sided adhesive tape 34 on the X2 side is disposed at a position offset toward the X1 side from the edge 20d on the X2 side.

[0027] The Z2-side adhesive surface of the double-sided adhesive tape 34 is fixed directly to the inner surface 20a, or indirectly to the inner surface 20a via a predetermined base or the like. The display panel 18 of this embodiment is a thin OLED panel, and a certain amount of space is created between it and the inner surface 20a. Therefore, the double-sided adhesive tape 34 is installed via a base (bracket) that fills this space. The Z1-side adhesive surface of the double-sided adhesive tape 34 is fixed to the back surface 18b of the display panel 18.

[0028] As shown in FIG. 3B, the display panel 18 can be supported by a plurality of cushion materials 36 on the back surface 18b of the four peripheral edges near the end surface 18c. The cushion materials 36 can be formed of sponge made of polyurethane, polyester, or the like. The cushion materials 36 have appropriate flexibility and elasticity and stably support the display panel 18. The cushion materials 36 can also be formed of soft rubber or the like. The Z2-side surface of the cushion materials 36 is fixed to the edge portion 20d of the inner surface 20a of the housing member 20 with double-sided adhesive tape or the like. The Z1-side surface (surface 36b) of the cushion materials 36 contacts and supports the back surface 1ba of the display panel 18.

[0029] As described above, the housing member 20 has a curved surface 20c, and the curved surface 20c is also formed on the edge portion 20d. Therefore, the outer surface 20b of the edge portion 20d is curved. On the other hand, the inner surface 20a of the edge portion 20d serves as the fixing surface (attachment surface) of the cushioning material 36. Therefore, it is preferable that the inner surface 20a of the edge portion 20d is flat.

[0030] This is because if the inner surface 20a of the edge portion 20d were a curved surface (offset surface) parallel to the outer surface 20b, there is a possibility that the cushion material 36 would not be able to support the display panel 18 with a sufficient contact area. Also, the edge portion 20d on the X2 side is formed integrally with the frame portion 27 and the bridge portion 28a between the embedded plate portion 28. For this reason, it is difficult to form the edge portion 20d on the X2 side as a curved surface (offset surface) parallel to the outer surface 20b in order to ensure a sufficient thickness for the bridge portion 28a.

[0031] It is also difficult to form the inner surface 20a of the edge portion 20d as a flat surface of the same height along its entire length. For example, consider a case where the entire length of the edge portion 20d extending in the Y direction on both sides in the X direction is a uniform flat surface. In this case, the frame portion 27 would be excessively thick near the center, where the curved shape 20c is most recessed, resulting in an increase in weight. Furthermore, a thicker frame portion 27 than the other portions would produce sink marks during injection molding of the resin material, and warping or dents due to shrinkage of the resin material could appear on the outer surface 20b, raising concerns about streaks or other imperfections.

[0032] Therefore, as shown in Figure 3A, the housing member 20 can have a plurality of flat surfaces 38-44 arranged in a stepped manner on the edge portion 20d. The flat surfaces 38-44 are planes along the X and Y directions. The stepped flat surfaces 38-44 can be provided at least on both sides of the edge portion 20d in the X direction, which are greatly influenced by the curved shape 20c and have a long overall length. Flat surfaces with appropriate steps can also be formed on both sides of the edge portion 20d in the Y direction. The number of flat surfaces 38-44 provided can be changed as appropriate depending on the curvature of the curved shape 20c and the length of the edge portion 20d.

[0033] Of the flat surfaces 38-44, flat surface 42 located at the bottom of curved shape 20c is located at the position furthest toward the Z2 side. Flat surfaces 38-41 located on the Y1 side of flat surface 42 are gradually offset toward the Z1 side in the Y1 direction. Similarly, flat surfaces 42 and 43 located on the Y2 side of flat surface 42 are gradually offset toward the Z1 side as they approach the Y2 side. For example, near the Y1-side end of edge portion 20d extending in the Y direction, flat surface 38 located furthest toward the Y1 side is at the highest position on the Z1 side. Flat surface 39 adjacent to flat surface 38 is located one step lower toward the Z2 side than flat surface 38. Flat surface 40 adjacent to flat surface 39 is located one step lower toward the Z2 side than flat surface 39.

[0034] A step 46 is provided at each boundary between the flat surfaces 38 to 44. The step 46 can be formed as an inclined surface that gradually slopes from one flat surface to the other. The step 46 can also be formed as a vertical surface in the Z direction.

[0035] The cushion material 36 is installed across the step 46 between at least some of the flat surfaces 38 to 44. If cushion material 36 were installed individually on all of the flat surfaces 38 to 44, the number of components for the cushion material 36 would increase, and the installation work would also increase. Furthermore, if the gap between the cushion materials 36, 36 lined up along the edge 20d increases, the stability of supporting the display panel 18 may decrease.

[0036] 3 denotes a conductive gasket attached to the flat surface 41. The conductive gasket 48 is a component that electrically contacts the rear surface 18b of the display panel 18 and electrically connects it to the hinge 14 for frame grounding.

[0037] Next, the structure of attaching the cushioning material 36 across the flat surfaces will be described, taking as an example the flat surfaces 39, 40 and their surrounding areas, in particular, where the difference in height of the step 46 is large.

[0038] Fig. 4A is a perspective view of the flat surfaces 39, 40 on the X1 side and their surrounding areas. Fig. 4B is a view showing a cushion material 36 placed across the flat surfaces 39, 40 shown in Fig. 4A. Fig. 5 is a schematic side cross-sectional view of the flat surfaces 39, 40 on the X1 side and their surrounding areas shown in Fig. 4B. The configuration of the flat surfaces 39, 40 on the X2 side and their surrounding areas is the same or similar to that shown in Figs. 4A to 5, except that they are bilaterally symmetrical.

[0039] 4A to 5, the cushion material 36 has a slit 36a at the portion spanning the step 46. The slit 36a is formed on the support surface (front surface 36b) that supports the back surface 18b of the display panel 18. The slit 36a is provided to prevent the cushion material 36 from unintentionally bulging at the position spanning the step 46 and pushing up the display panel 18.

[0040] The slits 36a are formed along the width direction (X direction) that intersects with the longitudinal direction (Y direction) of the cushion material 36. In other words, the cushion material 36, which straddles the flat surfaces 39 and 40, has the slits 36a formed along a direction that intersects (is perpendicular to) the direction from one flat surface 39 toward the other flat surface 40, which are arranged in a stepped manner. Because the cushion material 36 of this embodiment is installed linearly, the slits 36a are formed along the width direction that is perpendicular to the longitudinal direction of the cushion material 36. The slits 36a have a slit shape that is formed by cutting the surface 36b of the cushion material 36 with a sharp blade such as a cutter. The depth of the slits 36a (depth in the Z direction) can be set to a depth that does not completely cut through the cushion material 36, for example, approximately half the thickness of the cushion material 36.

[0041] As shown in FIG. 5, multiple slits 36a can be provided in a row along the longitudinal direction of the cushion material 36. The slits 36a can be formed on the surface 36b in at least a portion (range R1) spanning the step 46. The range R1 is, for example, a range covering the step 46 and portions of the flat surfaces 39, 40 close to the step 46 in the longitudinal direction of the cushion material 36. Preferably, the slits 36a can be formed on the surface 36b in a portion (range R2) spanning a boundary B between the step 46 and the flat surface 39 closer to the back surface 18b. In the configuration example shown in FIG. 5, the flat surface 39 is located closer to the Z1 side than the flat surface 40 and at a higher position closer to the back surface 18b of the display panel 18. The range R2 is a range covering the step 46 and portions of the flat surface 39 close to the step 46 in the longitudinal direction of the cushion material 36. Furthermore, the slits 36a should be formed at least directly above the boundary B.

[0042] Here, one procedure for attaching the cushion material 36 shown in FIGS. 4A to 5 will be described. The cushion material 36 is attached to the flat surfaces 39 and 40 using the double-sided adhesive tape 36c provided on the Z2 side. When attaching the cushion material 36 to the flat surfaces 39 and 40, the cushion material 36 is first attached to the flat surface 40 located at a lower position on the Z2 side. Next, while pulling the cushion material 36, with a portion thereof fixed to the flat surface 40, toward the Y1 side, the cushion material 36 is attached to the flat surface 39 located at a higher position on the Z1 side. At this time, the cushion material 36 has a slit 36a on the surface 36b in the range R1 or R2 that straddles the step 46. Therefore, the portion of the cushion material 36 that straddles the step 46 is pulled in the longitudinal direction, and the slit 36a expands in the longitudinal direction, forming a tear. This allows the cushion material 36 to smoothly overcome the step 46 and be smoothly attached so as to conform to the flat surfaces 39 and 40 (see FIG. 5).

[0043] FIG. 6 is a schematic cross-sectional side view showing a cushion material 36A according to a comparative example that does not have a slit 36a, placed on flat surfaces 39 and 40. As shown in FIG.

[0044] In actual work, it has been confirmed that cushion material 36A, which does not have slit 36a as shown in FIG. 6, may form mountain-shaped portions 36A1 in portions spanning step 46 (particularly boundary B) that are stretched when attached to flat surface 39 after being attached to flat surface 40. That is, when cushion material 36A is secured to flat surface 39 and then stretched to secure to flat surface 40, the portion spanning step 46 becomes excess length and rises, forming mountain-shaped portions 36A1. Mountain-shaped portions 36A1 push back surface 18b of display panel 18 toward Z1. As a result, display panel 18, pushed up by mountain-shaped portions 36A1, pushes back bezel member 22. As a result, bezel member 22 may lift off display surface 18a, forming gap G between them.

[0045] In particular, the display panel 18 of this embodiment is thin. Therefore, the display panel 18 is easily deformed toward the Z1 side by the upward pressure of the mountain-shaped portion 36A1, easily generating a gap G. The bezel member 22 is fixed to the display surface 18a with double-sided adhesive tape 22a attached to the Z2 side. However, the display panel 18 is an OLED panel, which makes it difficult to adhere the double-sided adhesive tape 22a. Therefore, if the mountain-shaped portion 36A1 is formed on the cushioning material 36, the bezel member 22 is even more likely to peel off from the display surface 18a. Such a gap G can significantly impair the appearance quality of the electronic device 10.

[0046] Therefore, the electronic device 10 has a slit 36a on the surface 36b of the cushion material 36 at least in the portion spanning the step 46. This allows the electronic device 10 to smoothly attach one piece of cushion material 36 to the flat surfaces 39, 40 arranged in a staircase pattern with the step 46 in between. As a result, the electronic device 10 can stably support the display panel 18 with the cushion material 36, and can also prevent the occurrence of gaps G due to peeling of the bezel member 22.

[0047] 4A to 5 show an example of a configuration in which slits 36a are formed in cushion material 36 that straddles predetermined flat surfaces 39, 40. Slits 36a may be formed in other cushion material 36 as long as the cushion material straddles a step and spans multiple flat surfaces. For example, in FIG. 3B, slits 36a are also formed in cushion material 36 that straddles flat surfaces 42, 43. Slits 36a may also be formed in cushion material 36 that extends in the X direction, for example, cushion material 36 that extends along edge 20d on the Y1 side.

[0048] At least one slit can somewhat prevent the formation of mountain-shaped portions 36A1 as shown in Figure 6. However, it is preferable to provide multiple slits 36a aligned in the direction in which flat surfaces 39, 40 are aligned. This allows cushioning material 36 to be attached more smoothly along step 46, further preventing the formation of mountain-shaped portions 36A1.

[0049] The flat surface 39 is located closer to the rear surface 18b of the display panel 18 than the flat surface 40 in the thickness direction (Z direction) of the housing member 20. In this case, the slit 36a is preferably provided at least in a portion (range R2) of the cushion material 36 that straddles the boundary B between the step 46 and the flat surface 39. That is, the cushion material 36 is likely to form a mountain-shaped portion 36A1 in the portion that straddles such boundary B. Therefore, by forming the slit 36a at least in the range R2 that straddles the boundary B, it is possible to effectively prevent the formation of the mountain-shaped portion 36A1 in the cushion material 36.

[0050] In this embodiment, the edge 20d of the housing member 20 can have a concave curved surface 20c that is recessed toward the center in a direction away from the back surface 18b of the display panel 18. In this case, the flat surfaces 39, 40 are arranged in a stepped pattern along the curved surface 20c of the edge 20d. This allows the housing member 20 (frame portion 27) on which the flat surfaces 39, 40 are formed to reliably form a flat surface on the inner surface 20a side that serves as the attachment surface for the cushioning material 36 while avoiding problems such as sink marks during molding.

[0051] In this embodiment, a double-sided adhesive tape 34 can be provided between the inner surface 20a of the housing member 20 and the back surface 18b of the display panel 18 as a support member for supporting the back surface 18b. The double-sided adhesive tape 34 supports a position closer to the center of the display panel 18 than the cushion material 36. This allows the double-sided adhesive tape 34 to reliably support the display panel 18 at a position that avoids steps or shaping formed on the inner surface 20a of the edge portion 20d. Furthermore, the outer peripheral portion of the display panel 18 that is closer to the end face 18c than the double-sided adhesive tape 34 can be supported by the cushion material 36, further improving support stability.

[0052] It should be noted that the present invention is not limited to the above-described embodiment, and can be freely modified without departing from the spirit of the present invention.

[0053] The slits 36a may be formed along the entire length of the cushion material 36. However, in order to improve the stability of the cushion material 36 in supporting the display panel 18, it is preferable that the slits 36a that will become tears are provided in the ranges R1 or R2.
