[0004] Sometimes, electronic devices such as lamps are housed within the housing. The lamp is fixed to the inner surface of the housing, with only the projection part exposed on the back surface. The lamp is connected to a cable. If adhesive tape is used to secure the display panel to such a housing, there is a concern that the tape may interfere with the cables of the electronic devices when it is stretched and peeled off. Summary of the Invention

[0005] The present invention was made in view of the above-mentioned problems, and its object is to provide an electronic device that does not interfere with the cables of electronic devices when stretching and peeling adhesive tape.

[0006] To solve the aforementioned problems and achieve the objective, the present invention relates to an electronic device having a rectangular housing on the back surface of a display panel. The housing has a first edge, a second edge opposite to the first edge, and a third and fourth edge orthogonal to the first and second edges. The electronic device includes: a stretchable and peelable first adhesive tape for fixing the display panel to the housing; electronic components disposed on the inner surface of the housing; and a cable connected to the electronic components. The first adhesive tape includes: a first adhesive portion along the first edge; and a first pull tab for stretching operations connected to the first adhesive portion. It comprises: a lateral extension extending further from the end of the first adhesive portion toward the third edge; and a longitudinal extension directly or indirectly connected to the lateral extension, extending along the third edge to the second edge, wherein the electronic device is disposed on the extension line of the lateral extension or on a side closer to the second edge than the extension line, and on the extension line of the longitudinal extension or on a side closer to the third edge than the extension line, wherein the cable, from a region closer to the second edge than the first adhesive portion and the lateral extension and closer to the fourth edge than the longitudinal extension, crosses the first pull tab at the portion including the lateral extension and detours to a region near the first edge to connect with the electronic device.

[0007] According to the above-described method of the present invention, there is no interference with the cables of electronic devices when stretching and peeling the adhesive tape. Attached Figure Description

Detailed Implementation

[0015] Hereinafter, embodiments of the electronic device according to the present invention will be described in detail with reference to the accompanying drawings. However, the present invention is not limited to these embodiments.

[0016] Figure 1 This is a schematic top view obtained from above, showing an electronic device 10 according to one embodiment. For example... Figure 1As shown, the electronic device 10 of this embodiment is a clamshell laptop PC, which is a structure in which the first housing 12 and the second housing 14 are rotatably connected relative to each other by a hinge 16. The first housing 12 is equipped with a display panel 18. The second housing 14 is equipped with a keyboard 20, a touchpad 21, etc., facing the upper surface 14a, and contains a motherboard, etc. Besides a laptop PC, the electronic device involved in this invention may also be a standalone display device, a tablet PC, a mobile phone, a smartphone, or a portable game console, etc.

[0017] Hereinafter, regarding the electronic device 10, based on the state where the first housing 12 is opened from the second housing 14 and the surfaces of the two are orthogonal (the angle between housings 12 and 14 is 90 degrees), from the perspective of a user visually recognizing the display panel 18, the left-right direction will be referred to as X1 and X2, the up-down direction as Y1 and Y2, and the depth direction as Z1 and Z2. Sometimes X1 and X2 are collectively referred to as the X direction, and Y1 and Y2, as well as Z1 and Z2, are sometimes also referred to as the Y direction and Z direction.

[0018] The first housing 12 is a flat box that is thinner than the second housing 14. The display surface 18a of the display panel 18 faces the Z1 side surface (front surface 12a) of the first housing 12. The first housing 12 has a housing cover 24 forming the Z2 side surface (back surface 12b) and a frame member 26 forming the peripheral portion of the front surface 12a. The top, bottom, left, and right side surfaces 12c of the first housing 12 are formed by upright walls 27 rising from the four peripheral portions of the housing cover 24. A hinge 16 connects the Y2 side edge of the first housing 12 to the Z2 side edge of the second housing 14.

[0019] The display panel 18 may be composed of, for example, a liquid crystal display (LCD) or an organic EL display (OLED). The display panel 18 may be constructed by laminating glass, a liquid crystal layer, and a light guide plate, and then fixing the outer edges of each layer together using double-sided tape, adhesive, or the like. The display panel 18 may also be a touch panel.

[0020] The housing cover 24 is a rectangle whose dimension in the Y direction is smaller than its dimension in the X direction when viewed from the front. The display panel 18 is a rectangle slightly smaller than the housing cover 24. In this application, the edge on the Y1 side is referred to as the first edge 28a, the edge on the Y2 side is referred to as the second edge 28b, the right edge is referred to as the third edge 28c, and the left edge is referred to as the fourth edge 28d when viewed from the front. In other words, the housing cover 24 is a rectangular component having the first edge 28a, the second edge 28b opposite to the first edge 28a, and the third edge 28c and the fourth edge 28d orthogonal to the first edge 28a and the second edge 28b, and covers the back surface of the display panel 18.

[0021] Multiple electronic devices 30 are disposed in the center of the frame member 26 along the first edge 28a, oriented toward the front surface. These electronic devices 30 include, for example, cameras, microphones, and infrared ports. The left and right ends of the frame member 26 along the second edge 28b are cut open and blocked by covers 31.

[0022] Figure 2 This is a top view showing the back surface of the first housing 12. A small lamp (electronic device) 32, indicating the power status, is positioned near the corner where the first edge 28a and the third edge 28c intersect on the housing cover 24. The lamp 32 is located on the inner surface of the housing cover 24, with the light-emitting portion 32a exposed on the outer surface. The lamp 32 is located at a corner, making it less likely to be obstructed by other objects. The lamp 32 is positioned above the first housing 12 when it is open relative to the second housing 14, making it easily visible from the rear. The distance from the lamp 32 to the first edge 28a is almost equal to the distance to the third edge 28c, resulting in a good design balance. It is preferable that the lamp 32 is positioned at the corner of the housing cover 24. The lamp 32 is, for example, an LED.

[0023] Figure 3 This is a schematic front view of the first housing 12 with the frame component 26 and display panel 18 removed. Figure 4 yes Figure 3 Enlarged view of the area around the intersection of the first edge 28a and the third edge 28c.

[0024] As described above, electronic components 30 are disposed along the first edge 28a of the housing 24. Multiple electronic components 30 are assembled together into a module 33. The first housing 12 and the second housing 14 are electrically connected via a flat cable 34. The flat cable 34 is, for example, an FPC, but may also be other types of cable. The flat cable 34 connects to the second housing 14 in the first housing 12 at a slightly rightward position, slopes midway towards the center, extends again along the Y1 direction, and reaches the vicinity of the first edge 28a to connect with the module 33.

[0025] In this embodiment, the flat cable 34 branches into a first branch cable 36, a second branch cable 38, and a third branch cable 40. The first branch cable 36 and the second branch cable 38 extend parallel to each other near the first edge 28a. The second branch cable 38 is adjacent to the right side of the first branch cable 36 and is thinner than the first branch cable 36. The third branch cable 40 further branches from near the front end of the second branch cable 38 and connects to the lamp 32. The third branch cable 40 is also simply referred to as cable 40. Cable 40 will be further described later.

[0026] The housing 24 and the display panel 18 are secured by a first adhesive tape 42, a second adhesive tape 44, a third adhesive tape 46, and a fourth adhesive tape 48. These adhesive tapes are double-sided tapes and have stretchable peel-off properties; they are referred to as stretch-release tapes, stretchable double-sided tapes, or stretchable tapes. Such components exhibit high adhesive strength when not stretched, while their adhesive strength decreases when stretched. Each adhesive tape is essentially separate.

[0027] The first adhesive tape 42 includes a first adhesive portion 42a and a first pull tab 42b. The second adhesive tape 44 includes a second adhesive portion 44a and a second pull tab 44b. The third adhesive tape 46 includes a third adhesive portion 46a and a third pull tab 46b. The fourth adhesive tape 48 includes a fourth adhesive portion 48a and a fourth pull tab 48b. Each adhesive portion is a part that has an adhesive function. Each pull tab is a part used for stretching operations and does not have an adhesive function. Each adhesive portion is shown in a dotted pattern.

[0028] The second adhesive strip 44 is straight. The second adhesive portion 44a is disposed almost along the entire length in immediate vicinity of the third edge 28c. The second pull tab 44b extends a short distance from the Y2 side end of the second adhesive portion 44a towards the second edge 28b. The second adhesive portion 44a is located between the first adhesive strip 42 and the third edge 28c.

[0029] The first adhesive portion 42a extends to the right along the first edge 28a from near the right side of module 33. The first pull tab 42b includes: a lateral extension 42ba, which extends shortly from the end of the first adhesive portion 42a towards the third edge 28c; a longitudinal extension 42bb, which extends along the third edge 28c to the second edge 28b; and a bent portion 42bc, which bends away from the first edge 28a and the third edge 28c between the lateral extension 42ba and the longitudinal extension 42bb. That is, the lateral extension 42ba and the longitudinal extension 42bb are indirectly connected via the bent portion 42bc. As will be described later, a lamp 32 is provided in the inner circumferential region of the curve formed by the bent portion 42bc. That is, the bent portion 42bc is a path that avoids the lamp 32. However, depending on the arrangement of the lamp 32, the bent portion 42bc may be omitted and the lateral extension 42ba and the longitudinal extension 42bb may be directly connected.

[0030] The third adhesive tape 46 omits the bent portion 42bc of the first adhesive tape 42 and is arranged symmetrically with the first adhesive tape 42. The fourth adhesive tape 48 has the same shape as the second adhesive tape 44 and is arranged symmetrically with the second adhesive tape 44.

[0031] The front ends 42c, 44c, 46c, and 48c of each pull tab 42b, 44b, 46b, and 48b extend to a position on the second edge 28b that does not overlap with the display panel 18. The front ends 42c, 44c, 46c, and 48c are typically covered by a cover 31, which is removed to expose them, allowing for the pulling operation. To save space, the front ends 42c and 44c, and 46c and 48c, may overlap.

[0032] As described above, the lamp 32 is located within the area avoided by the buckled portion 42bc. Specifically, it is partially or entirely located within the extended width of the transverse extension 42ba and within the extended width of the longitudinal extension 42bb. Thus, the lamp 32 can be appropriately positioned at the corner of the housing cover 24.

[0033] Cable 40 is composed of a shorter first portion 40a connected to the second branch cable 38 in a crank-like manner, a longer second portion 40b extending laterally, and an inverted U-shaped third portion 40c connected to the lamp 32. The second portion 40b connects the first portion 40a and the third portion 40c. At least the third portion 40c and its vicinity of the cable 40 are not bonded to the housing cover 24. The second portion 40b is located in region A1 (see reference) of the area closer to the Y2 side (one side of the second edge 28b) than the first bonded portion 42a and the lateral extension 42ba and closer to the X1 side (one side of the fourth edge 28d) than the longitudinal extension 42bb. Figure 4 Extending within. In this embodiment, the second portion 40b is adjacent to and parallel to the first adhesive portion 42a on the Y2 side (one side of the second edge 28b) compared to the first adhesive portion 42a. Figure 4 In this embodiment, taking the intersection point C of the extension line L1 of the horizontal extension 42ba and the extension line L2 of the vertical extension 42bb as a reference, region A1 roughly corresponds to the lower left side. In this embodiment, due to reasons such as the branching of the third cable 40 from the second cable 38 and its positional relationship with the module 33, the second part 40b is located in region A1 instead of region A2 (see reference). Figure 4 Region A2 is located on the Y1 side (closer to the first edge 28a) than the first adhesive portion 42a and the transverse extension portion 42ba. Figure 4 The intersection point C is roughly equivalent to the upper left side.

[0034] The third part 40c is a detour section that bypasses the transverse extension 42ba and the bend 42bc of the first pull tab 42b, detours to region A2, and connects to the lamp 32. The layering arrangement in this part is: housing 24, first pull tab 42b, third part 40c, and display panel 18. That is, in the assembly process of the electronic device 10, the adhesive tapes 42, 44, 46, and 48 are already attached to the housing 24. A flat cable 34, including the cable 40, is then configured, and the display panel 18 is installed. Since the third part 40c of the cable 40 does not need to pass under the first pull tab 42b, it can directly cover the first pull tab 42b, thus shortening the operation time.

[0035] In this embodiment, the third portion 40c is not only on the transverse extension 42ba, but also partially on the bend 42bc, but essentially crosses the first tab 42b at the location including the transverse extension 42ba. The cable 40 is arranged to not contact the first adhesive portion 42a and the second adhesive portion 44a.

[0036] Figure 5 This diagram illustrates the steps for removing adhesive tapes 42 and 44. Figure 5 (a) indicates the first stage. Figure 5 (b) indicates the second stage. Figure 5 (c) indicates the third stage. Figure 5 (d) indicates the final stage. When removing adhesive tapes 42 and 44, remove cover 31 in advance to expose the front ends 42c and 44c.

[0037] like Figure 5 As shown in (a), firstly, the front end 44c is pulled forward and the second adhesive tape 44 is pulled. Figure 5 As shown in (b), grasp the front end 42c and pull it upwards to the upper right. The longitudinal extension 42bb of the first pull tab 42b is pulled out from the gap between the housing cover 24 and the display panel 18.

[0038] like Figure 5 As shown in (c), the longitudinal extension 42bb faces along the X direction, and the first adhesive strip 42 has a slightly undulating shape from the transverse extension 42ba to the buckled portion 42bc, but the first adhesive portion 42a and the first pull tab 42b are approximately straight along the X direction. At this time, for the first adhesive strip 42, the portion of the main buckled portion 42bc enters the inside of the U-shape formed by the third portion 40c, and no unreasonable force is applied to the third portion 40c and the lamp 32.

[0039] Furthermore, if the first pull tab 42b is pulled towards the X2 side, the adhesive force of the first adhesive portion 42a decreases, and the first adhesive portion 42a and the transverse extension portion 42ba are pulled apart through the inner side of the U-shape formed by the third portion 40c. At this time, unreasonable force will not be applied to the third portion 40c and the lamp 32. Figure 5 As shown in (d), with the first pull tab 42b pulled out, the cable 40 and lamp 32 are correctly maintained in their initial positions. Furthermore, the removal of the fourth adhesive tape 48 is the same as the removal of the second adhesive tape 44, and the removal of the third adhesive tape 46 is the same as the removal of the first adhesive tape 42. Once each of the adhesive tapes 42, 44, 46, and 48 is removed, the display panel 18 can be removed from the housing cover 24.

[0040] Thus, in the electronic device 10 according to this embodiment, the cable 40, from region A1, crosses the first pull tab 42b at the portion including the transverse extension 42ba and detours to region A2 to connect with the lamp 32. Therefore, as Figure 5 (b) Figure 5 As shown in (d), there is no interference with the cable 40 when the first adhesive tape 42 is stretched and peeled off. When the display panel 18 is reinstalled, the lamp 32 remains in the correct position without the need for reinstallation or replacement. In addition, the first adhesive portion 42a of the first adhesive tape 42 can be positioned in a predetermined position by passing under the second portion 40b of the cable 40.

[0041] As described above, lamp 32 is located within the extended width of the horizontal extension 42ba and within the extended width of the vertical extension 42bb. However, even when it is positioned on the extension line L1 of the horizontal extension 42ba or on the Y1 side of the extension line L1, and on the extension line L2 of the vertical extension 42bb or on the X2 side of the extension line L2 (in... Figure 4 When in region A3 (right side), the third portion 40c of cable 40 also crosses the first pull tab 42b from region A1 at the location including the transverse extension 42ba and detours to region A2, thereby avoiding interference with the first adhesive tape 42. Figure 4 As shown by the imaginary line, when lamp 32 is located in area A1 or area A2, there is no need for a avoidance path in the third part 40c. The connection destination of cable 40 is not limited to lamp 32, but can also be electronic devices such as microphones, sensors, and displays.

[0042] This invention is not limited to the above-described embodiments, and can of course be freely modified without departing from the spirit of this invention.
