Summary of the Invention

Problems to be Solved by the Invention

[0004] An electronic device as described above employs a lightweight and thin display panel such as an OLED (Organic Light Emitting Diode) panel as the display panel, aiming to make the entire device thinner and lighter. A lightweight and thin display panel is likely to float and sink, for example, when touched or when the edge of the housing is gripped, and the floating and sinking at the outer peripheral edge in particular may be conspicuous in terms of appearance. In particular, when a bezel member is attached to the outer peripheral edge of the display panel, there is also a concern that a gap will occur between the panel surface when the display panel moves.

[0005] Therefore, it is conceivable to support the panel by interposing a cushioning material between the outer peripheral edge of the display panel and the inner surface of the housing member. However, the inner surface of the housing member may not be formed as a uniform flat surface due to relationships with internal components, design, etc. In this case, if a raised portion forms in the cushioning material, this portion may push up the display panel, making stable support difficult.

[0006] This invention has been made in consideration of the problems of the prior art described above, and aims to provide an electronic device that can stably support a display panel. [Means for solving the problem]

[0007] An electronic device according to one aspect of the present invention comprises a housing member and a display panel having a display surface, the back surface opposite to the display surface being supported on the inner surface side 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 manner with a step between them, positioned opposite to the back surface of the display panel, and further comprising a cushioning material attached to the first flat surface and the second flat surface, straddling the step, and supporting the back surface of the display panel on its surface, wherein the cushioning material is provided on the surface of at least the portion straddling the step, and has a slit formed along a second direction intersecting a first direction from the first flat surface toward the second flat surface. [Effects of the Invention]

[0008] According to the above-described embodiment of the present invention, the display panel can be stably supported. [Brief explanation of the drawing]

[Modes for carrying out the invention]

[0010] Hereinafter, preferred embodiments of the electronic device according to the present invention will be described in detail with reference to the attached drawings.

[0011] Figure 1 is a schematic plan view of an electronic device 10 according to one embodiment, viewed from above. As shown in Figure 1, the electronic device 10 of 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 able to rotate relative to each other. In this embodiment, a notebook PC electronic device 10 is used as an example, but the electronic device may be other than a notebook PC, for example, a standalone display device, a tablet PC, a smartphone, or a portable game console.

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

[0013] The first housing 11 is a flat box. The first housing 11 mounts a display panel 18. Hereinafter, regarding the first housing 11 and each component mounted thereon, based on the direction seen from a user who views the display surface 18a of the display panel 18, the left - right direction is respectively called the X1, X2 directions, the up - down direction is respectively called the Y1, Y2 directions, and the depth direction (thickness direction) is respectively called the Z1, Z2 directions for explanation. The X1, X2 directions may be collectively called the X direction, and the Y1, Y2 directions and Z1, Z2 directions may also be similarly called the Y direction and Z direction respectively.

[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 forming the Z2 - side surface and a bezel member 22 forming the outer periphery of the Z1 - side surface. The upper, lower, left, and right side surfaces of the first housing 11 are formed by standing walls 23 rising from the four - peripheral edges of the housing member 20. The bezel member 22 is a frame - shaped thin plate surrounding the outer - peripheral edge 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 by a rod - shaped hinge cover extending in the X direction.

[0015] The display panel 18 is composed of, for example, an OLED panel. The OLED panel is lightweight and thin. The display panel 18 is supported on the inner - surface 20a side of the housing member 20 with the back surface 18b facing the Z2 side on the opposite side of the display surface 18a.

[0016] FIG. 2 is a schematic side view of the housing member 20. FIG. 3A is a schematic plan view of the housing member 2 having been viewed from the inner - surface 20a side. In FIG. 3A, the outer shape of the display panel 18 is shown by a two - dot chain line. FIG. 3B is a view in which members for supporting the display panel 18 are installed on the housing member 20 shown in FIG. 3A.

[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 the present embodiment has a dome-shaped curved surface 20c that smoothly bulges 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 shape on the Z2 side by the curved surface 20c. The reference numeral 20c1 in FIG. 3A is 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 a part of the curved surface 20c.

[0019] The curved surface 20c also extends to the edge 20d of the housing member 20. The standing wall 23 constitutes a part of the edge 20d, and its height in the Z direction is substantially the same throughout the circumference. The edge 20d forms a part of the curved surface 20c by being formed to bulge toward the Z2 side from the Z2-side end of the standing wall 23 toward the vicinity of the central portion of the housing member 20. Therefore, as shown in FIG. 2, for example, the left and right edges 20d extending in the Y direction on both sides in the X direction are arcuately curved so as to gradually sink toward the Z2 side near the central portion in the longitudinal direction (Y direction).

[0020] The plate portion 26 is a plate that serves as the base of the housing member 20 and forms most of the central portion of the housing member 20. The plate portion 26 is a carbon fiber reinforced resin plate (CFRP plate) formed by laminating a plurality of layers of prepregs impregnated with a matrix resin (e.g., a thermosetting resin such as an epoxy resin or a thermoplastic resin) in a carbon resin. The plate portion 26 may be configured to sandwich an intermediate material such as a foam 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 a carbon fiber reinforced resin. The plate portion 26 may be formed of the same or different types 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 them together. The frame portion 27 is laminated on the inner surface of the outer peripheral edge of the plate portion 26, and the portion that covers the outer peripheral end surface of the plate portion 26 becomes the edge portion 20d. The frame portion 27 can be formed from, for example, PCCF (carbon fiber reinforced polycarbonate). A plate portion 26 made of CFRP is light and high strength, but it has problems in terms of workability for machining and shaping. Therefore, the housing member 20 is provided with a frame portion 27 made of resin material around the plate portion 26, and various shapes such as the edge portion 20d and screw holes are formed on this frame portion 27.

[0022] The embedded plate portion 28 is formed to fill an opening formed in a part of the plate portion 26. The embedded plate portion 28 can be integrally formed from the same resin material as the frame portion 27. 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 or a small lamp on the outer surface 20b of the housing member 20. The logo displays the product name or manufacturer name of the electronic device 10 by string of characters, a figure, or a mark, or a combination thereof. The lamp is formed by, for example, an LED and can display the operating status of the electronic device 10.

[0023] The enclosure member 20, with its curved shape 20c, can secure a certain amount of height space between its inner surface 20a and the back surface 18b of the display panel 18. As shown in Figures 3A and 3B, the central part (bottom) of the curved shape 20c, which is most recessed towards Z2, serves as the 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 the motherboard etc. on the second enclosure 12 side via an FPC (flexible printed circuit board).

[0024] Reference numeral 32 in Figure 3 indicates a metal bracket for connecting the hinge 14 to the housing member 20. The bracket 32 ​​is fixed to the Y2-side edge 20d of the inner surface 20a of the housing member 20, and is provided in pairs, for example, on the left and right sides.

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

[0026] As shown in Figure 3B, the display panel 18 can be supported by the housing member 20 via double-sided adhesive tape 34 installed on the inner surface 20a. The double-sided adhesive tape 34 can be made of, for example, a stretch-release tape, stretch double-sided tape, or Lala tape. The double-sided adhesive tape 34 has the property of being peelable by tensile force by pulling a tab at one end. The double-sided adhesive tape 34 has, for example, a strip shape extending along the Y direction, and a pair is provided on the left and right sides in the X direction. The double-sided adhesive tape 34 is fixed at a position offset towards the center from the end faces 18c on both sides in the X direction of the display panel 18 (see Figures 3A and 3B). The edges 20d at both the left and right ends of the inner surface 20a have shapes processed or screw holes formed to follow the inner wall of the vertical wall 23. Therefore, the double-sided adhesive tape 34 is installed at a position that avoids these. Specifically, the double-sided adhesive tape 34 on the X1 side is installed at a position offset towards the X2 side from the edge 20d on the X1 side. Similarly, the double-sided adhesive tape 34 on the X2 side is installed in a position offset towards 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 either directly fixed to the inner surface 20a or indirectly fixed to the inner surface 20a via a predetermined base or the like. The display panel 18 in this embodiment is a thin OLED panel, and there is a certain amount of space 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 Figure 3B, the display panel 18 can be supported by multiple cushioning materials 36 on the back surfaces 18b of the four peripheral edges near the end face 18c. The cushioning material 36 can be made of a sponge made from, for example, polyurethane or polyester. The cushioning material 36 has appropriate flexibility and elasticity and stably supports the display panel 18. The cushioning material 36 can also be made of soft rubber or the like. The Z2 side surface of the cushioning material 36 is fixed to the edge 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 cushioning material 36 contacts and supports the back surface 1ba of the display panel 18.

[0029] Incidentally, as described above, the housing member 20 has a curved shape 20c, and this curved shape 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 becomes the fixing surface (adhesion surface) of the cushioning material 36. For this reason, it is preferable that the inner surface 20a of the edge portion 20d be a flat surface.

[0030] If the inner surface 20a of the edge portion 20d were a curved surface (offset surface) parallel to the outer surface 20b, the cushioning material 36 might not be able to support the display panel 18 with a sufficient contact area. In addition, the edge portion 20d on the X2 side is formed integrally with the frame portion 27 and the bridge portion 28a with 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 sufficient thickness of 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 the 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 becomes heavier due to the excessive thickness of the edge portion 20d near the most recessed central part of the curved shape 20c. Furthermore, the frame portion 27, which is thicker than the others, may develop sink marks during injection molding of the resin material, causing warping and dents due to shrinkage of the resin material, and raising concerns that streaks and other patterns may appear on the outer surface 20b.

[0032] As shown in Figure 3A, the housing member 20 can have a plurality of flat surfaces 38-44 arranged in a stepped manner along the edge 20d. The flat surfaces 38-44 are planes along the XY direction. The stepped flat surfaces 38-44 can be provided at least on the edges 20d on both sides in the X direction, where the influence of the curved shape 20c is significant and the overall length is long. Flat surfaces with appropriate steps can also be formed on the edges 20d on both sides in the Y direction. The number of flat surfaces 38-44 installed can be appropriately changed depending on the curvature of the curved shape 20c and the length of the edge 20d.

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

[0034] Steps 46 are provided at the mutual boundaries between the flat surfaces 38 to 44. The steps 46 can be formed by inclined surfaces that gradually slope from one flat surface to the other. The steps 46 can also be formed by vertical surfaces in the Z direction.

[0035] The cushioning material 36 is installed across the step 46 between two flat surfaces 38-44 for at least a portion of each flat surface 38-44. If the cushioning material 36 were installed individually on all flat surfaces 38-44, the number of parts for the cushioning material 36 would increase, and the labor required for installation would also increase. Furthermore, if the gap between the cushioning materials 36, 36 arranged along the edge 20d increases, the support stability of the display panel 18 may decrease.

[0036] Reference numeral 48 in Figure 3 indicates a conductive gasket attached to the flat surface 41. The conductive gasket 48 makes electrical contact with the back surface 18b of the display panel 18 and is a component that electrically connects it to the hinge 14 to form a frame ground.

[0037] Next, the structure for attaching the cushioning material 36 across flat surfaces will be explained, with particular emphasis on the flat surfaces 39 and 40 and their surrounding areas where the height difference of the step 46 is large.

[0038] Figure 4A is a perspective view of the flat surfaces 39 and 40 on the X1 side and their surrounding areas. Figure 4B shows the cushioning material 36 installed so as to span the flat surfaces 39 and 40 shown in Figure 4A. Figure 5 is a schematic side cross-sectional view of the flat surfaces 39 and 40 on the X1 side and their surrounding areas shown in Figure 4B. The configuration of the flat surfaces 39 and 40 on the X2 side and their surrounding areas is the same or similar as those shown in Figures 4A to 5, except that it is symmetrical.

[0039] As shown in Figures 4A to 5, the cushioning material 36 has a cut 36a in the portion that straddles the step 46. The cut 36a is formed on the support surface (surface 36b) that supports the back surface 18b of the display panel 18. The cut 36a is provided to prevent the cushioning material 36 from unintentionally bulging at the position where it straddles the step 46 and pushing up the display panel 18.

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

[0041] As shown in Figure 5, multiple cuts 36a can be provided in a row along the longitudinal direction of the cushioning material 36. The cuts 36a can be formed on the surface 36b of the portion (range R1) that straddles the step 46. Range R1 is, for example, the range in the longitudinal direction of the cushioning material 36 that covers the step 46 and the portion of the flat surfaces 39, 40 that is close to the step 46. Preferably, the cuts 36a can be formed on the surface 36b of the portion (range R2) that straddles the boundary B between the step 46 and the flat surface 39 on the side closer to the back surface 18b. In the example configuration shown in Figure 5, the flat surface 39 is on the Z1 side of the flat surface 40 and is at a high position close to the back surface 18b of the display panel 18. Range R2 is the range in the longitudinal direction of the cushioning material 36 that covers the step 46 and the portion of the flat surface 39 that is close to the step 46. Furthermore, it is preferable that the cuts 36a be formed at least on the portion directly above the boundary B.

[0042] Here, we will explain one procedure for attaching the cushioning material 36 shown in Figures 4A to 5. The cushioning material 36 is attached to the flat surfaces 39 and 40 using double-sided adhesive tape 36c provided on the side of Z2. When attaching the cushioning material 36 to the flat surfaces 39 and 40, first, the cushioning material 36 is attached to the flat surface 40 at the lower position on the Z2 side. Next, while pulling the cushioning material 36, which is partially fixed to the flat surface 40, towards the Y1 side, the cushioning material 36 is attached to the flat surface 39 at the higher position on the Z1 side. At this time, the cushioning material 36 has a cut 36a on the surface 36b of the area R1 or R2 that straddles the step 46. As a result, the portion of the cushioning material 36 that straddles the step 46 is pulled in the longitudinal direction, causing the cut 36a to expand in the longitudinal direction and form a tear. This allows the cushioning material 36 to smoothly overcome the step 46 and be smoothly fixed to follow the flat surfaces 39 and 40 (see Figure 5).

[0043] Figure 6 is a schematic side cross-sectional view showing the cushioning material 36A, which is a comparative example without a cut 36a, installed on flat surfaces 39 and 40.

[0044] In actual work, it has been confirmed that cushioning material 36A, which does not have the cut 36a shown in Figure 6, can form a mountain-shaped portion 36A1 in the part that crosses the step 46 (especially boundary B) that is stretched when it is attached to the flat surface 39 after being attached to the flat surface 40. That is, when the cushioning material 36A is stretched and fixed to the flat surface 40 after being fixed to the flat surface 39, the part that crosses the stretched step 46 becomes excess length and bulges, forming a mountain-shaped portion 36A1. The mountain-shaped portion 36A1 pushes the back surface 18b of the display panel 18 upward towards Z1. As a result, the display panel 18, which is pushed up by the mountain-shaped portion 36A1, pushes up the bezel member 22. As a result, there were cases in which the bezel member 22 lifted up from the display surface 18a, and a gap G was formed between them.

[0045] In particular, the display panel 18 in this embodiment is thin. As a result, the display panel 18 is easily deformed towards Z1 by the upward pressure of the mountain-shaped portion 36A1, and a gap G is easily created. The bezel member 22 is fixed to the display surface 18a with double-sided adhesive tape 22a provided on the side of Z2. On the other hand, the display panel 18 is an OLED panel, which has properties that make it difficult to adhere double-sided adhesive tape 22a to it. As a result, 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 cut 36a on the surface 36b of the cushioning material 36 at least in the portion that straddles the step 46. This allows the electronic device 10 to smoothly attach one cushioning material 36 to the flat surfaces 39 and 40 that are arranged in a stepped manner on either side of the step 46. As a result, the electronic device 10 can stably support the display panel 18 with the cushioning material 36, and the occurrence of gaps G due to peeling of the bezel member 22 can also be suppressed.

[0047] Figures 4A to 5 illustrate a configuration in which a cut 36a is formed in a cushioning material 36 that spans predetermined flat surfaces 39 and 40. The cut 36a may also be provided in other cushioning materials 36 if the cushioning material spans multiple flat surfaces across a step. For example, in Figure 3B, a cut 36a is also provided in the cushioning material 36 that spans flat surfaces 42 and 43. The cut 36a may also be formed in a cushioning material 36 that extends in the X direction, for example, in a cushioning material 36 along the edge 20d on the Y1 side.

[0048] At least one cut can suppress to some extent the occurrence of the mountain-shaped portion 36A1 shown in Figure 6. However, it is preferable that multiple cuts 36a are provided in a row along the direction in which the flat surfaces 39 and 40 are aligned. This allows the cushioning material 36 to be attached more smoothly along the step 46, and further suppresses the occurrence of the mountain-shaped portion 36A1.

[0049] The flat surface 39 is located closer to the back 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, it is preferable that the cut 36a is provided at least in the portion (range R2) where the cushioning material 36 straddles the boundary B between the step 46 and the flat surface 39. That is, the cushioning material 36 is prone to forming a mountain-shaped portion 36A1 in the portion where it crosses such a boundary B. Therefore, by forming the cut 36a at least in the range R2 that straddles the boundary B, the formation of a mountain-shaped portion 36A1 in the cushioning material 36 can be effectively suppressed.

[0050] In this embodiment, the edge portion 20d of the housing member 20 can have a concave curved surface shape 20c that is recessed toward the center and away from the back surface 18b of the display panel 18. In this case, the flat surfaces 39 and 40 are arranged in a stepped manner along the curved surface shape 20c of the edge portion 20d. As a result, the housing member 20 (frame portion 27) on which the flat surfaces 39 and 40 are formed can reliably form a flat surface on the inner surface 20a side that will serve as the surface for attaching the cushioning material 36, while avoiding problems such as shrinkage 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, serving as a support member for the back surface 18b. The double-sided adhesive tape 34 supports the display panel 18 at a position closer to the center than the cushioning material 36. This allows the double-sided adhesive tape 34 to reliably support the display panel 18 at a position that avoids steps and shape processing formed on the inner surface 20a of the edge 20d. Furthermore, since the outer peripheral portion of the display panel 18 closer to the end surface 18c than the double-sided adhesive tape 34 can be supported by the cushioning material 36, the support stability is further improved.

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

[0053] The cuts 36a may be formed to run along the entire length of the cushioning material 36. However, in order to improve the support stability of the display panel 18 by the cushioning material 36, it is preferable that the cuts 36a, which form the slits, be provided in the range R1 or R2.
