Description

[Technical field]

[0001] The present invention relates to electronic devices. [Background technology]

[0002] Electronic devices such as notebook PCs are equipped with a display panel such as a liquid crystal display. It is desirable for the display panel to be removable for maintenance. Therefore, Patent Document 1 discloses a configuration in which the display panel is fixed using a double-sided adhesive tape that can be stretched and peeled off. [Prior art documents] [Patent documents]

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

[0004] In the above-mentioned configuration in which the display panel is fixed with double-sided adhesive tape, a handle (tab) for gripping during tensile peeling must be protruded from the side of the display panel. However, electronic devices such as the above-mentioned notebook PCs usually adopt housings with narrow frame structures that limit the space around the display panel. For this reason, a thin and small tab may stick to the inner wall surface of a vertical wall in this narrow space. In that case, it is difficult to smoothly grip the tab even with a thin tool such as tweezers, and the workability during tensile peeling of the double-sided adhesive tape is reduced.

[0005] The present invention has been made in consideration of the above-mentioned problems with the conventional technology, and has an object to provide an electronic device that can improve the ease of use when pulling and peeling a double-sided adhesive tape. [Means for solving the problem]

[0007] An electronic device according to a second aspect of the present invention comprises a housing member having a vertical wall on an edge, a display panel having a display surface, a back surface opposite the display surface supported by the inner surface of the housing member and an outer peripheral side surface arranged opposite the vertical wall, and a double-sided adhesive tape having a property that allows it to be pulled and peeled by pulling a tab, and fixing the back surface of the display panel to the inner surface of the housing member, and a protrusion having a width narrower than the width of the tab is provided on the inner wall surface of the vertical wall.

[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] Fig. 1 is a schematic plan view of an electronic device 10 according to an embodiment, seen from above. As shown in Fig. 1, the electronic device 10 according to the present embodiment is a clamshell-type notebook PC, in which a first housing 11 and a second housing 12 are connected by a hinge 14 so as to be relatively rotatable. In the present embodiment, the electronic device 10 is a notebook PC, but the electronic device may be, for example, a standalone display device, a tablet PC, a smartphone, a portable game machine, or the like, other than the notebook PC.

[0012] The second housing 12 is a flat box 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, a battery device, a memory, an antenna device, etc. are housed. A keyboard 16 and a touch pad 17 face the top surface of the second housing 12.

[0013] The first housing 11 is a flat box that is thinner than the second housing 12. 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 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 be similarly 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 (front surface 11a) of the first housing 11. The first housing 11 has a housing member 20 forming the Z2 side surface (rear surface 11b) and a bezel member 22 forming the peripheral portion of the front surface 11a. The top, bottom, left and right side surfaces of the first housing 11 are formed by upright walls 23 standing from the four peripheral portions of the housing member 20. The bezel member 22 is a frame-shaped thin plate that surrounds the outer peripheral portion of the display panel 18. The front surface 11a of the first housing 11, including the bezel member 22, is covered with a touch glass 24 almost entirely. The hinge 14 is connected to the Y2 side edge (lower edge 11c) of the first housing 11.

[0015] The display panel 18 is composed of, for example, a liquid crystal display or an organic EL display. The display panel 18 has a structure in which, for example, glass, a liquid crystal layer, a light guide plate, etc. are laminated and the outer peripheral edges of each layer are fixed to each other with double-sided tape, adhesive, etc. The touch glass 24 covers the display surface 18a to form a touch panel that accepts touch operations on the display panel 18.

[0016] Fig. 2 is a schematic front view of the first housing 11. Fig. 2 omits illustration of the touch glass 24 and the bezel member 22, and illustrates the outline of the display panel 18 by a two-dot chain line. That is, Fig. 2 mainly illustrates the inner surface 20a (the surface behind the rear surface 11b) of the housing member 20 and the double-sided adhesive tape 26 adhered to the inner surface 20a.

[0017] As shown in Fig. 2, the housing member 20 has a configuration in which, for example, a frame portion 20B is joined to the outer peripheral edge portion of a plate portion 20A (see also Figs. 4A to 5B). The standing wall 23 is formed on the frame portion 20B. The plate portion 20A is, for example, a laminated plate made of carbon fiber reinforced resin. The frame portion 20B is a resin frame joined to the edge portion of the plate portion 20A by injection molding. The housing member 20 may have a configuration in which the plate portion 20A and the frame portion 20B are integrally formed from the same resin material or the like.

[0018] The standing wall 23 forms the outer peripheral side surface of the first housing 11, and its Z1 side surface becomes the attachment surface of the bezel member 22. The housing member 20 has a part of the standing wall 23 on the lower edge portion 11c side cut out, and a pair of left and right brackets 28 are adhesively fixed to the inner surface 20a of the cutout. The brackets 28 are metal parts for screwing the hinges 14.

[0019] On the inner surface 20a of the housing member 20, a pair of double-sided adhesive tapes 26 extending in, for example, the Y direction are provided on the left and right sides. The double-sided adhesive tape 26 is an adhesive tape for fixing the display panel 18 to the housing member 20. The double-sided adhesive tape 26 adhesively fixes the back surface 18b opposite the display surface 18a of the display panel 18 to the inner surface 20a of the housing member 20 (see Figs. 4A to 5B). In this embodiment, the left and right double-sided adhesive tapes 26, 26 have different shapes and arrangements, but each has the same or similar functions and effects. The number of double-sided adhesive tapes provided may be one or three or more.

[0020] 5A and 5B, steps and curved surfaces are formed on the inner surface 20a of the housing member 20. The steps are formed, for example, between the plate portion 20A and the frame portion 20B. The curved surface is formed on the inner surface of the plate portion 20A, which is curved in a dome shape. Therefore, the double-sided adhesive tape 26 may be indirectly fixed to the inner surface 20a via a bracket or the like that corrects the steps and curved surface to a flat surface.

[0021] The double-sided adhesive tape 26 is, for example, what is called a stretch release tape, a stretch double-sided tape, or a lara tape. The double-sided adhesive tape 26 has a property that it can be pulled and peeled off by pulling a tab 26a at one end. The double-sided adhesive tape 26 has an adhesive layer 26b on both sides of the portion other than the tab 26a. The tab 26a does not have an adhesive layer 26b or the adhesive layer 26b is covered with a film or the like to prevent it from being adhered to other parts. This allows the user to smoothly grab and pull the tab 26a. The tab 26a may be made of a sheet member separate from the double-sided adhesive tape 26, and this sheet member may be connected to the end of the double-sided adhesive tape 26.

[0022] 2, the tabs 26a of each double-sided adhesive tape 26 are disposed on the sides of the outer peripheral side surface 18c of the display panel 18, and are disposed in recessed portions 30 formed in the standing wall 23. The recessed portions 30 in this embodiment are formed in the standing wall 23 constituting the Y1-side edge portion (upper edge portion 11d) of the first housing 11. The recessed portions 30 may be provided in the lower edge portion 11c of the first housing 11 or in the standing wall 23 on the left and right edges extending along the Y direction.

[0023] Next, the configuration of the recessed portion 30 and its surroundings, and the manner in which the tab 26aa is disposed in the recessed portion 30 will be described.

[0024] FIG. 3 is an enlarged perspective view of the recessed portion 30 and its periphery. In FIG. 3, the touch glass 24 and the bezel member 22 are omitted, and the outer shape of the double-sided adhesive tape 26 is illustrated by a two-dot chain line. FIG. 4A is an enlarged plan view of the recessed portion 30 and its periphery. FIG. 4B is a plan view showing a state in which the display panel 18 is attached to the housing member 20 shown in FIG. 4A using the double-sided adhesive tape 26. FIG. 5A is a schematic cross-sectional view along the line VA-VA in FIG. 4B. FIG. 5B is a schematic cross-sectional view along the line VB-VB in FIG. 4B. FIGS. 3 to 5B representatively show the double-sided adhesive tape 26 on the left side in FIG. 2, and the recessed portion 30 on the left side where the tab 26a is arranged, and its periphery, but the right side can be a symmetrical structure or the same or similar structure as the left side.

[0025] 3 to 5B, the standing wall 23 has a recessed portion 30 at a position facing the outer peripheral side surface 18c of the display panel 18. The recessed portion 30 in this embodiment is provided in the standing wall 23 that forms the upper edge portion 11d, and therefore faces the outer peripheral side surface 18c on the Y1 side extending in the X direction along the upper edge portion 11d.

[0026] The recessed portion 30 has a shape in which the inner wall surface 23a of the standing wall 23 facing the outer peripheral side surface 18c is cut out in a recessed shape in the Y1 direction. The width of the recessed portion 30 along the longitudinal direction (X direction) of the standing wall 23 is larger than the width of the tab 26a. In other words, the width of the recessed portion 30, which is the sum of the widths W2 to W4 in FIG. 3, is larger than the width W1 of the tab 26a. This allows the tab 26a to be smoothly accommodated in the recessed portion 30.

[0027] The recessed portion 30 has a protruding portion 32 on an inner wall surface 30a facing the outer peripheral side surface 18c. The protruding portion 32 has a width W2 smaller than the width of the recessed portion 30, and is a rib extending approximately in the Z direction along the inner wall surface 30a. The width W1 of the tab 26a is, for example, 6 mm. The width W2 of the protruding portion 32 is, for example, 0.5 mm, which is narrower than the tab 26a. In addition, the widths W2 and W3 of the gaps between the pair of side wall surfaces 30b and 30c on both sides of the recessed portion 30 in the X direction and the protruding portion 32 are both narrower than the width W1 of the tab 26a. The widths W2 and W3 are, for example, 5 mm. Therefore, the tab 26a is always installed in contact with the tip surface 32a of the protruding portion 32 without fitting into the gaps of widths W2 and W3 in the recessed portion 30.

[0028] It is preferable that the width W2 of the protrusion 32 is 0.5 mm or a value close to this. This makes it possible to prevent sink marks from appearing on the outer surface of the standing wall 23 during injection molding of the frame portion 20B, which are caused by a difference in thickness of the standing wall 23 between a portion of the inner wall surface 30a of the recessed portion 30 where the protrusion 32 is present and a portion where the protrusion 32 is not present.

[0029] 4A, the protrusion 32 in this embodiment is disposed at the center of the inner wall surface 30a in the longitudinal direction (X direction). However, as long as the magnitude relationship of the widths W1 to W4 described above is ensured, the protrusion 32 does not necessarily have to be disposed at the center of the inner wall surface 30a.

[0030] As shown in FIG. 5A, the tip surface 32a of the protrusion 32 extends in a ridge-like shape while gradually inclining in the Y1 direction away from the outer peripheral side surface 18c of the display panel 18 toward the rising direction (Z1 direction) of the standing wall 23 from the inner surface 20a of the housing member 20. It is preferable that the tip surface 32a has an inclination change portion 32b in the middle of its extension direction, where the inclination angle in the Y1 direction changes. With the inclination change portion 32b as a reference, the tip surface 32a has a larger inclination angle in a portion farther from the inner surface 20a (portion 32d on the Z1 side of the inclination change portion 32b) than in a portion closer to the inner surface 20a of the housing member 20 (portion 32c on the Z2 side of the inclination change portion 32b). Therefore, the portion 32c of the tip surface 32a rises at a steep angle close to a right angle with respect to the inner surface 20a, and the portion 32d extends so as to lie down at an angle more gentle than the portion 32c.

[0031] Next, the operation of pulling and peeling the double-sided adhesive tape 26 via the tab 26a and the effect thereof will be described.

[0032] 3 to 5B, in a state in which the display panel 18 is fixed to the housing member 20 with the double-sided adhesive tape 26, the tab 26a is disposed in the recessed portion 30 between the outer peripheral side surface 18c and the inner wall surface 30a. At this time, a part of the back surface of the tab 26a abuts against the tip surface 32a of the protruding portion 32, and the tab 26a is in a position standing up toward approximately the Z1 side.

[0033] In this state, most of the back surface of the tab 26a protrudes to the side of the protrusion 32, and the tab 26a does not contact the inner wall surface 30a at all (see FIG. 5B), or is slightly tilted so that only one side edge in the width direction is slightly in contact with the inner wall surface 30a. Therefore, a relatively large gap G1 in the Y direction is formed between the tab 26a and the inner wall surface 30a. Furthermore, in this state, the front surface of the tab 26a does not contact the outer peripheral side surface 18c of the display panel 18 at all (see FIG. 5B), or is slightly tilted so that only one side edge in the width direction is slightly in contact with the outer peripheral side surface 18c. Therefore, a relatively large gap G2 in the Y direction is also formed between the tab 26a and the outer peripheral side surface 18c.

[0034] When the double-sided adhesive tape 26 is pulled and peeled from this state, as shown in Figs. 5A and 5B, the touch glass 24 and the bezel member 22 are peeled off to expose the tab 26a. Then, the Z1 side openings of the gaps G1 and G2 are exposed. Then, a tool 34 such as tweezers is inserted from above into the gaps G1 and G2 to grasp the tab 26a. Then, the tab 26a is pulled in the Z1 and Y1 directions. Then, the double-sided adhesive tape 26 is gradually thinned while the adhesive layer 26b is peeled off from the back surface 18b of the display panel 18 and the inner surface 20a of the housing member 20, and the display panel 18 can be smoothly pulled out to the side.

[0035] In this case, in the electronic device 10 of this embodiment, the back surface 18b of the display panel 18 is fixed to the inner surface 20a of the housing member 20 by the double-sided adhesive tape 26 having a property that allows for tensile peeling by pulling the tab 26a. The standing wall 23 has a recessed portion 30 in which the tab 26a of the double-sided adhesive tape 26 is disposed, at a position facing the outer peripheral side surface 18c of the display panel 18. The inner wall surface 30a of the recessed portion 30 is provided with a protruding portion 32 having a width W2 narrower than the width W1 of the tab 26a.

[0036] Therefore, when the tab 26a is placed in the recessed portion 30, a part of the width W1 of the tab 26a is supported by the narrow protruding portion 32, and the remainder of the tab 26a protrudes laterally from the protruding portion 32 to form a gap G1 between the tab 26a and the inner wall surface 30a of the recessed portion 30. Therefore, when the double-sided adhesive tape 26 is pulled and peeled off, the electronic device 10 can smoothly grasp the tab 26a by inserting a tool 34 such as tweezers into this gap G1, improving the workability when pulling and peeling off the double-sided adhesive tape 26. As a result, the electronic device 10 improves reworkability in factories, maintenance services, and the like, and also improves production efficiency.

[0037] The electronic device 10 has a recessed portion 30 in the standing wall 23, and a protruding portion 32 in the recessed portion 30. Therefore, even though the electronic device 10 has a narrow frame structure in which the space between the outer peripheral side surface 18c of the display panel 18 and the inner wall surface 23a of the standing wall 23 is extremely narrow, the gap G1, which is the insertion space for the tool 34, can be more reliably secured.

[0038] In particular, the inner wall surface 30a of the recessed portion 30 is a smoothly curved surface to avoid stress concentration due to impact when the electronic device 10 is dropped. For this reason, without the protruding portion 32, there is a high concern that the tab 26a pressed by the display panel 18 will stick closely to the inner wall surface 30a as shown in the comparative example of FIG. 6. Therefore, by providing the protruding portion 32 in the electronic device 10, it is possible to prevent the thin and small tab 26a from sticking to the inner wall surface 30a of the recessed portion 30 as shown in the comparative example of FIG. 6, and to ensure the gap G1 as described above. Note that FIG. 6 shows a side cross-sectional view of a configuration according to a comparative example in which the tab 26a is arranged in the recessed portion 30 without the protruding portion 32.

[0039] Incidentally, when the display panel 18 is installed, the tab 26a is pushed toward the inner wall surface 30a. At this time, if the width W2 of the protrusion 32 is equal to or greater than the width W1 of the tab 26a, there is a concern that the tab 26a may stick to the protrusion 32, or may be pushed back from the protrusion 32 toward the outer peripheral side surface 18c and stick to the outer peripheral side surface 18c. In this regard, in the electronic device 10, the width W2 of the protrusion 32 is narrower than the width W1 of the tab 26a, and the width W2 is set to, for example, 10% or less of the width W1. Therefore, when the display panel 18 is installed, the tab 26a is in a position that is inclined moderately to the left or right of the protrusion 32 while abutting against the protrusion 32. As a result, the entire surface of the tab 26a does not stick to the tip surface 32a or the outer peripheral side surface 18c, and the gap G2 can be secured, which has the advantage of more reliably securing the space for inserting the tool 34.

[0040] In the recessed portion 30, it is preferable that the widths W2, W3 of the gaps between the left and right side wall surfaces 30b, 30c and the protruding portion 32 are both narrower than the width W1 of the tab 26a. This prevents the tab 26a from getting stuck in the gaps on the sides of the protruding portion 32 inside the recessed portion 30, and ensures the gap G1 even more reliably.

[0041] The tip surface 32a of the protrusion 32 may be configured to extend in a ridge-like shape while gradually inclining in a direction away from the outer peripheral side surface 18c of the display panel 18 in the direction in which the standing wall 23 rises from the inner surface 20a of the housing member 20. In this way, the thin and small tab 26a can be stably received by the protrusion 32, and the above-mentioned gaps G1 and G2 are stably secured.

[0042] In particular, the tip surface 32a of the protrusion 32 may have an inclination change portion 32b whose inclination angle changes, and the inclination angle of a portion 32d farther from the inner surface 20a may be greater than that of a portion 32c closer to the inner surface 20a, based on the inclination change portion 32b. In this case, as shown in Figures 5 and 5B, the tab 26a abuts against the portion 32c and takes an upright position, so that the above-mentioned gaps G1 and G2 are more stably secured.

[0043] The protrusion 32 may have a configuration other than the ridge-like configuration extending in the Z direction as shown in FIG. 5A. For example, instead of the protrusion 32, a protrusion-like or pin-like protrusion 32A shown by a two-dot chain line in FIG. 5B may be used. Even with such a protrusion 32A, it is possible to ensure the gaps G1 and G2 in a manner similar to that of the protrusion 32 described above. However, as described above, the protrusion 32 extending in a ridge-like configuration has the advantage that the gaps G1 and G2 can be formed more stably than the protrusion-like protrusion 32A. In addition, since the width W2 of the protrusion 32 is extremely small, for example, 0.5 mm, in the case of the protrusion-like or pin-like protrusion 32A, there is a problem that the protrusion 32A is taken by the mold or easily broken during injection molding of the frame part 20B. In this regard, the protrusion 32 extending in a ridge-like configuration has the advantage that such problems are unlikely to occur because sufficient strength can be ensured.

[0044] Fig. 7 is an enlarged plan view of a main part showing a mounting structure of the protrusion 32 according to a modified example. As shown in Fig. 7, the electronic device 10 may be configured to have the protrusion 32 (32A) directly on the inner wall surface 23a of the standing wall 23 without providing the recessed portion 30. However, in a configuration in which the space between the standing wall 23 and the outer peripheral side surface 18c is extremely narrow or in order to achieve a further narrowing of the bezel member 22, a configuration in which the recessed portion 30 is provided is more preferable, since it is easy to ensure the insertion space for the tool 34 while minimizing the space.

[0045] It should be noted that the present invention is not limited to the above-described embodiment, and can of course be freely modified without departing from the spirit and scope of the present invention. [Explanation of symbols]
