Description

The present invention relates to a display device.

In recent years, there has been a demand for thinner display devices, and in Patent Document 1, this is achieved by removing the bezel. However, to protect the substrates and other components attached to the chassis that provide the strength of the display device, a cover is required. To achieve a thinner cover and improve appearance, a structure has been adopted in which the edges of the cover are positioned at an acute angle to the display panel, rather than a box-shaped cover encasing the display panel.

International Publication No. WO2019/123871

However, with the above-mentioned conventional technology, heat generated within the display device causes thermal expansion of the chassis and cover, and the difference in thermal expansion causes the cover to warp, creating a gap between the edge of the cover and the chassis. This gap has drawbacks, such as a reduction in appearance quality, insulation problems, and the intrusion of dust and other particles. For this reason, it is common to use additional parts on the edge to seal the gap.

One aspect of the present invention aims to reduce gaps that occur at the edges of the cover.

In order to solve the above problem, a display device according to one aspect of the present invention comprises a first member having a first fastening portion and a second member having a second fastening portion facing the first fastening portion, one of the first member and the second member being a chassis and the other being a cover that covers the chassis, the first member being made of resin, the direction from the first member to the second member being a first direction, and by screwing the first fastening portion and the second fastening portion together, a first edge of the first member is displaced in the first direction or pressed against a member on the first direction side.

One aspect of the present invention makes it possible to reduce gaps that occur around the edges of the cover.

[Embodiment 1]
Hereinafter, one embodiment of the present invention will be described in detail with reference to FIGS.

(Configuration of display device)
1 is a perspective view showing the appearance of a display device 1 according to embodiment 1. The display device 1 includes a display panel 2, a stand 3, a chassis (second member) 100, a substrate (not shown), and a cabinet (first member, cover) 200. A bezel (not shown) may be provided around the periphery of the display panel 2.

The display panel 2 is a liquid crystal display panel that displays images. The display panel 2 is not limited to a liquid crystal display panel, but may also be an organic EL (electroluminescence) display panel.

The chassis 100 is a metal sheet member that maintains the strength of the display device 1. The display panel 2 and chassis 100 are integrated by some means such as engagement, fastening, or adhesion. For example, the display panel 2 and chassis 100 may be integrated with adhesive or double-sided tape. Alternatively, a fixing member fixed with adhesive may be provided on the side of the display panel 2 opposite the surface that displays the image, and the chassis 100 may be fixed to this fixing member.

The stand 3 is made of metal and resin and is used to hold the display panel 2 upright. The stand 3 is fixed to the chassis 100.

The board is a circuit board equipped with a circuit that generates a video signal from an input signal and outputs it to the display panel 2. The board is fixed to the chassis 100.

The cabinet 200 is a resin component provided to prevent dirt, dust, and the like from adhering to the circuit board. Therefore, the cabinet 200 is fixed to the chassis 100 and covers at least a portion of the chassis 100. For example, in Figure 1, the cabinet 200 covers the lower half of the chassis 100.

(Configuration of cabinet 200)
Fig. 2 is a front view of the cabinet 200 according to the first embodiment. Fig. 3 is a top view of the cabinet 200 according to the first embodiment.

The height of the cabinet 200 may be about half the height of the chassis 100, in which case the cabinet 200 is a structure that covers only the lower half of the chassis 100.

The cabinet 200 has a flat cover portion 210 that extends almost flat near the center when viewed from the front. The cabinet 200 has curved cover portions 220 that curve so as to protrude in an arch shape toward the front from the left and right ends of the flat cover portion 210. The cabinet 200 also has upper and lower cover portions 230 that cover the top and bottom surfaces of the flat cover portion 210 and the curved cover portion 220. The edges of the curved cover portion 220 and the upper and lower cover portions 230 are edge portions 240. In other words, the edge portions 240 are the edges (top, bottom, left, and right edges) of the cabinet 200.

The cabinet 200 is provided with a number of bosses with bolt holes that protrude from the rear side to the front side. The bosses can be broadly classified into two types: outer edge bosses (first fastening parts) 250 that are located only on the outer periphery of the cabinet 200 (positioned along the outer edge), and internal bosses 260 that are the other bosses excluding the outer edge bosses 250.

The internal boss 260 is a general boss for mechanically screwing together the cabinet 200 and the chassis 100 or other structural members. In contrast, the outer edge boss 250 is a special boss provided only on the outer edge of the cabinet 200. The outer edge boss 250 functions to bring the outer periphery (edge 240) of the cabinet 200 as close as possible to (closely contact) the chassis 100 by screwing together the cabinet 200 and the chassis 100 at the outer edge boss 250.

Furthermore, bolt holes 251 (holes for fastening) are provided in the outer edge boss 250, and bolt holes are provided in the internal boss 260. The shapes of the bolt holes 251 and the bolt holes in the internal boss 260 are not limited to circular holes and may be any shape. For example, in consideration of thermal expansion, elongated holes extending radially from the center of the component (cabinet 200) may be provided.

(Configuration of chassis 100)
Fig. 4 is a front view of the chassis 100 according to the first embodiment. Fig. 5 is a top view of the chassis 100 according to the first embodiment.

The chassis 100 has a plate-like portion 110 that extends almost flat. The outer edge of the plate-like portion 110 is folded twice at 90° angles so that it appears concave when viewed from the front, and the four corners of the chassis 100 form protruding ears 120. The display panel 2 may be attached to these ears 120 using double-sided tape.

In addition, the chassis 100 has many convex shapes formed when viewed from the rear. Of these many convex shapes, the convex portions extending in the longitudinal or lateral directions are ribs 130, which are structures that maintain the strength of the chassis 100.

Of the many convex shapes, the convex portions facing the outer edge boss 250 and the internal boss 260 of the cabinet 200 are convex portions (second fastening portions) 140 for fastening other structural components. For example, convex portion 140 is formed with tap 141 (see Figure 7) in which a burring tap is cut from the rear side to the front side. Tap 141 is a female screw provided for fastening other components to the chassis 100. Tap 141 is formed on convex portion 140 to ensure a space for the screw to escape when a bolt is fastened using tap 141.

(Outer edge boss 250)
FIG. 6 is a perspective view showing the appearance of the outer edge boss 250 according to the first embodiment. FIG. 7 is a cross-sectional view showing the function of the outer edge boss 250 according to the first embodiment. As shown in FIG. 7 , the chassis 100 and the cabinet 200 are stacked, and the outer edge boss 250 and the protrusion 140 face each other. Note that in the cross section of FIG. 7 , the right side (center side) of the protrusion 140 is connected to an even higher protrusion (such as a rib). FIG. 7 shows the relationship between the chassis 100 and the cabinet 200 in an unscrewed state. Furthermore, FIG. 7 illustrates an example of the outer edge boss 250 provided on the curved cover portion 220, but this is not limiting, and the outer edge boss 250 may also be provided on the flat cover portion 210.

The parallel surface 142 around the tap 141 of the convex portion 140 is a plane parallel to the plate-shaped portion 110 and the display screen of the display panel 2. In contrast, an inclined surface 252 inclined relative to the plate-shaped portion 110 and the display screen of the display panel 2 is formed on the front side of the outer edge boss 250.

The inclined surface 252 is inclined so that it is closer to the chassis 100 as it approaches the center of the cabinet 200, and so that it is farther away from the chassis 100 as it approaches the outer edge of the cabinet 200. In other words, the distance between the outer edge boss 250 and the convex portion 140 when not fastened with screws is smaller at the center of the cabinet 200 than at the edge (edge portion 240) of the cabinet 200. The parallel surface 142 and the inclined surface 252 form an angle θ greater than 0°. In other words, the angle θ formed by the surface of the outer edge boss 250 facing the convex portion 140 and the surface of the convex portion 140 facing the outer edge boss 250 is greater than 0°. For example, the angle θ is preferably 3° or greater, and around 5°, before being fastened with screws.

The surface of outer edge boss 250 opposite inclined surface 252 is referred to as fastening surface 253. Fastening surface 253 may be parallel to parallel surface 142 or parallel to inclined surface 252. When fastening surface 253 is parallel to the tap plane, a mold for cabinet 200 can be easily made. On the other hand, when fastening surface 253 is parallel to inclined surface 252, when chassis 100 and cabinet 200 are fastened with a bolt, the thickness of outer edge boss 250 (the distance from inclined surface 252 to fastening surface 253) is uniform, allowing bolt 300 to be fastened appropriately.

The cabinet 200 (particularly the curved cover portion 220) may warp due to differences in thermal expansion between the chassis 100 and the cabinet 200. Therefore, even if the dimensions of the edge 240 are designed so that the edge 240 exactly abuts the chassis 100, during use, a gap 241 may form between the chassis 100 and the edge 240 of the cabinet 200 due to the warping of the cabinet 200. This gap 241 can cause defects such as a decrease in appearance quality, insulation problems, or the intrusion of dust, etc.

Figure 8 is a cross-sectional view of the outer edge boss 250 according to embodiment 1 when the inclined surface 252 and the parallel surface 142 according to embodiment 1 are in contact. As shown in Figure 8, the chassis 100 and the cabinet 200 are fastened to each other by bolts 300.

By screwing the outer edge boss 250 and the protrusion 140 together, the angle θ that was present in Figure 7 is reduced, and in Figure 8, θ becomes 0 or nearly 0. As a result, a displacement occurs in the cabinet 200 in a direction that changes the angle θ from the outer edge boss 250 to the outside (edge 240 side). In other words, for example, in Figure 8, by screwing the outer edge boss 250 and the protrusion 140 together, the edge 240 of the cabinet 200 rotates toward the chassis 100, with the outer edge boss 250 as the fulcrum. It can be said that by screwing, the cabinet 200 is deformed so that the edge 240 approaches the chassis.

In other words, by fastening the outer edge boss 250 and the protrusion 140 together with screws, the edge 240 of the cabinet 200 is brought closer to the chassis 100 (displaced in the direction from the cabinet 200 toward the chassis 100 (first direction, front direction) or pressed against a member on the first direction side), thereby reducing or eliminating the gap 241 that occurs due to thermal expansion, etc.

Note that, from a design perspective (when there is no difference in thermal expansion between the chassis 100 and the cabinet 200), the edge 240 may just abut against the chassis 100 without being fastened with screws. In this case, the edge 240 is pressed against the chassis 100 by fastening the outer edge boss 250 and the protrusion 140 to each other with screws. This makes it less likely that gaps 241 will occur due to warping of the cabinet 200. Note that the edge 240 may be displaced toward the display panel 2 or pressed against the display panel 2 when fastened with screws.

Note that, by design, a gap may exist between the edge 240 and the chassis 100 when not screwed. In this case, by screwing the outer edge boss 250 and the protrusion 140 together, the edge 240 will abut or be slightly pressed against the chassis 100. In this case, too, the cabinet 200 is deformed in advance in the direction opposite to the warp due to the screw fastening, so gaps 241 due to warping of the cabinet 200 are less likely to occur. Note that the edge 240 may be configured to abut or be pressed against the display panel 2 side when screwed.

(Direction of inclined surface 252)
9 is a model diagram showing the direction of inclination of the inclined surface 252 according to the first embodiment. In FIG. 9 , the base of the arrow corresponds to the portion where the gap between the outer edge boss 250 and the protrusion 140 is narrow, and the tip of the arrow corresponds to the portion where the gap between the outer edge boss 250 and the protrusion 140 is wide. As shown in FIG. 9 , the inclined surface 252 of each of the plurality of pairs of outer edge bosses 250 and protrusions 140 faces in a different direction for each of the outer edge bosses 250. That is, the cabinet 200 and the chassis 100 have a plurality of pairs of outer edge bosses 250 and protrusions 140, and the direction (second direction) from the portion where the gap between the outer edge boss 250 and the protrusion 140 is wide to the portion where the gap is narrow varies depending on the position of the outer edge boss 250 on the cabinet 200.

The second direction of the inclined surface 252 may vary depending on the distance from the edge 240. In other words, the second direction from the widest part to the narrowest part between the outer edge boss 250 and the protrusion 140 varies depending on the position of the outer edge boss 250 relative to the edge 240.

Specifically, there are a first outer edge boss 2501 and a second outer edge boss 2502, the distances from edge 242, which is a specific side of edge 240, being D1 and D2, respectively. D2 is a distance greater than D1. In this case, because second outer edge boss 2502 is farther from edge 242 than first outer edge boss 2501, the second direction of inclined surface 252 of first outer edge boss 2501 faces toward edge 242 more than the second direction of inclined surface 252 of second outer edge boss 2502. That is, of at least two outer edge bosses 2501, 2502 that are at different distances from the edge 242 (second edge) of the cabinet 200, the one with the smaller distance has a second direction, from the widest part of the outer edge boss 2501, 2502 to the narrowest part of the spacing relative to the protrusion 140, that faces the edge 242.

Although the explanation has been given with respect to a specific edge 242, the same applies to other edges of the edge 240. Therefore, the direction (vector) of the inclined surface 252 tends to point toward the vertex (corner) near the edge 240. However, for an outer edge boss 250 positioned at a position corresponding to the center of the edge 240, the nearby vertices are equidistant, so the direction (vector) is perpendicular to the edge 240.

For example, in Figure 9, the first outer edge boss 2501 is located at the four corners of the edge 240, and the second outer edge boss 2502 is located approximately in the center of the four sides of the edge 240. Due to the distance between the second outer edge boss 2502 and the neighboring edge 240, the inclined surface 252 of the second outer edge boss 2502 faces in a direction (V2) perpendicular to the nearest edge 240. In contrast, due to the distance between the first outer edge boss 2501 and the neighboring edge 240, the inclined surface 252 of the first outer edge boss 2501 faces in a direction (V1) facing the vertex where two sides of the neighboring edge 240 intersect. Therefore, V1 faces the edge 242 more than V2.

The direction of the inclined surface may be determined not only based on the distance to the edge 240, but also, for example, based on the relationship with the apex of the edge 240. Furthermore, in addition to the relationship with the distance to the edge 240, the structure of the cabinet 200 may also be taken into consideration. For example, the angle of the edge 240 relative to the chassis 100 may also be taken into consideration.

By determining the inclined surface 252 based on its position relative to the cabinet 200 or its position relative to the edge 240, it becomes easier to bring each edge 240 closer to the chassis 100.

[Embodiment 2]
Other embodiments of the present invention will be described below. For ease of explanation, the same reference numerals will be used to designate components having the same functions as those described in the above embodiment, and the description thereof will not be repeated.

Figure 10 is a perspective view showing the appearance of the outer edge boss 250a according to embodiment 2. Figure 11 is a cross-sectional view showing the function of the outer edge boss 250a according to embodiment 2. As shown in Figure 11, the chassis 100 and the cabinet 200 are stacked, and the outer edge boss 250a and the protrusion 140 face each other.

Unlike outer edge boss 250, outer edge boss 250a does not have an inclined surface 252. Instead, outer edge boss 250a has a protrusion 254. Outer edge boss 250a has protrusion 254 located closer to the center of cabinet 200 than bolt hole 251, which is a hole for fastening.

The protrusion 254 and the imaginary plane 252a passing through the opposite side of the bolt hole 251 from the protrusion 254 correspond to the inclined surface 252 in embodiment 1. That is, the parallel surface 142 and the imaginary plane 252a form an angle θ that is greater than 0°. Furthermore, the outer edge boss 250a contacts the parallel surface 142 at the protrusion 254, and the distance between the outer edge boss 250a and the convex portion 140 due to the protrusion 254 is smaller at the center of the cabinet 200 than at the edge (first edge) side of the cabinet 200.

Therefore, by screwing the outer edge boss 250a and the protrusion 140 together, the edge 240 of the cabinet 200 rotates toward the chassis 100, using the protrusion 254 as a fulcrum, allowing the edge 240 of the cabinet 200 to move closer to the chassis 100.

In embodiment 2, it is easier to create the angle θ between the outer edge boss 250a and the protrusion 140 than in embodiment 1. Specifically, in the mold for the cabinet 200, a recess is made in the area corresponding to the outer edge boss 250a, and the protrusion 254 can be formed by injection molding.

In addition, the protrusion 254 may be a member that engages with the outer edge boss 250a. Specifically, the outer edge boss 250a may have a recess, into which a member that corresponds to the protrusion 254 may be inserted. In this case, by replacing the parts of the protrusion 254, the angle θ formed between the parallel surface 142 and the imaginary plane 252a can be changed, which has the advantage of enabling adjustment.

[Embodiment 3]
Other embodiments of the present invention will be described below. For ease of explanation, the same reference numerals will be used to designate components having the same functions as those described in the above embodiment, and the description thereof will not be repeated.

Figure 12 is a perspective view showing the appearance of the outer edge boss 250b according to embodiment 3. Figure 13 is a cross-sectional view showing the function of the outer edge boss 250b according to embodiment 3. As shown in Figure 13, the chassis 100 and the cabinet 200 are stacked, and the outer edge boss 250b and the protrusion 140 face each other.

Unlike outer edge boss 250, outer edge boss 250b does not have an inclined surface 252 formed therein. Instead, a spacer 256 having an inclined surface 252b equivalent to inclined surface 252 is added between outer edge boss 250b and protrusion 140. In other words, a spacer 256 is provided between outer edge boss 250b and protrusion 140, with the center side of cabinet 200 being higher and the edge (first edge) side of cabinet 200 being lower. Spacer 256 may be made of resin or metal. Spacer 256 has a hole or notch through which a bolt passes, at a position corresponding to bolt hole 251 of outer edge boss 250b.

The spacer 256 and the outer edge boss 250b are fixed at the joint surface 255 using double-sided tape or the like. The joint surface 255 is the surface of the spacer 256 opposite the inclined surface 252b. The joint surface 255 may be parallel to the parallel surface 142. In other words, the surface of the outer edge boss 250b on which the bolt hole 251 is formed may have a typical boss shape that is parallel to the parallel surface 142.

The inclined surface 252b and the parallel surface 142 form an angle θ that is greater than 0°. Furthermore, the distance between the spacer 256 and the protrusion 140 is smaller at the center of the cabinet 200 than at the edge of the cabinet 200.

Therefore, by screwing the outer edge boss 250b and the protrusion 140 together, the edge 240 of the cabinet 200 rotates toward the chassis 100, using the spacer 256 as a fulcrum, allowing the edge 240 of the cabinet 200 to approach the chassis 100.

In embodiment 3, unlike embodiment 1, the angle θ can be adjusted by replacing the spacer 256. Also, unlike embodiment 2, the screw fastening is performed using a surface, allowing for strong screw fastening. Furthermore, since it is only necessary to insert the spacer 256 between the parallel surface 142 and a general outer edge boss 250b having a surface parallel to the parallel surface 142, it is also possible to reduce the gap by retrofitting the spacer 256 in a device that was not designed to reduce the gap.

Here, the spacer 256 is fixed to the outer edge boss 250b, but this is not limited thereto and it may also be fixed to the convex portion 140. The reason why the spacer 256 needs to be fixed to either the outer edge boss 250b or the convex portion 140 is to prevent the spacer 256 from rotating as the bolt 300 rotates and to prevent the direction of the inclined surface 252b from changing.

[Modification]
In the first to third embodiments, the inclined surfaces 252, 252a, 252b are provided on the cabinet 200 side, but this is not limitative, and the convex portion 140 of the chassis 100 may be inclined.

Furthermore, although the cabinet is made of resin and the chassis is made of metal, this is not limiting. For example, the cabinet may be made of metal and the chassis may be made of resin.

Furthermore, although it has been described that the direction of the inclined surface 252 is determined by the distance from the edge 240, this is not limiting. For example, the inclined surface 252 may be provided radially from the center of the cabinet 200.

〔summary〕
A display device according to aspect 1 of the present invention comprises a first member having a first fastening portion and a second member having a second fastening portion opposite the first fastening portion, one of the first member and the second member being a chassis and the other being a cover covering the chassis, the first member being made of resin, the direction from the first member to the second member being a first direction, and by screwing the first fastening portion and the second fastening portion together, the first edge of the first member is displaced in the first direction or pressed against a member on the first direction side.

With the above configuration, by screwing the first member and the second member together using the first fastening portion and the second fastening portion, the first edge of the first member can be brought closer to the second member in the first direction. This prevents objects from getting between the first edge of the first member and the second member. For example, if the first member is a cover and the second member is a chassis, the member on the first direction side may be the chassis or a display panel.

A display device according to Aspect 2 of the present invention may be similar to Aspect 1 above, in that the first fastening portion and the second fastening portion are fastened together with screws, so that the first edge of the first member rotates toward the second member, with the first fastening portion as a fulcrum.

With the above configuration, by fastening the first fastening portion and the second fastening portion together with screws, the first member can be rotated around the first fastening portion as a fulcrum, bringing the first edge of the first member closer to the second member.

A display device according to aspect 3 of the present invention may be the same as in aspect 1 or 2 above, wherein the distance between the first fastening portion and the second fastening portion when not fastened with screws is smaller at the center of the first member than at the first edge of the first member.

With the above configuration, the distance between the first fastening portion and the second fastening portion is smaller at the center of the first member than at the first edge of the first member, so the edge of the first member can be brought closer to the second member by fastening with a screw.

A display device according to Aspect 4 of the present invention is any one of Aspects 1 to 3 above, wherein the angle formed by the surface of the first fastening portion facing the second fastening portion and the surface of the second fastening portion facing the first fastening portion may be reduced by fastening with the screw.

With the above configuration, the angle formed by the surface of the first fastening part facing the second fastening part and the surface of the second fastening part facing the first fastening part is reduced by screw fastening, allowing the edge of the first member to be closer to the second member.

A display device according to aspect 5 of the present invention is the display device of aspect 1 or 2 above, wherein the first fastening portion may include a protrusion located closer to the center of the first member than the fastening hole.

With the above configuration, by providing a protrusion closer to the center of the first member than the fastening hole in the first fastening, the distance between the first fastening portion and the second fastening portion is smaller at the center of the first member than at the first edge of the first member, so that the edge of the first member can be brought closer to the second member by fastening with a screw.

A display device according to Aspect 6 of the present invention may be the same as Aspects 1 or 2 above, but may further include a spacer between the first fastening portion and the second fastening portion, the spacer being higher on the center side of the first member and lower on the first edge side of the first member.

With the above configuration, a spacer, in which the center side of the first member is higher and the first edge side of the first member is lower, can be inserted between the first fastening portion and the second fastening portion, and by fastening with a screw, the edge of the first member can be brought closer to the second member.

A display device according to aspect 7 of the present invention is any one of aspects 1 to 6 above, wherein the first member and the second member have multiple pairs of the first fastening portion and the second fastening portion, and the second direction, from the widest to the narrowest spacing of the first fastening portion relative to the second fastening portion, may vary depending on the position of the first fastening portion relative to the second edge of the first member.

With the above configuration, the direction in which the spacing of the first fastening portion relative to the second fastening portion changes from wide to narrow may be different for each of the multiple first fastening portions. This makes it possible to select an appropriate direction depending on the position of the first fastening portion relative to the second edge of the first member, efficiently bringing the second edge of the first member closer to the second member.

A display device according to aspect 8 of the present invention is the same as in aspect 7 above, wherein, of at least two of the first fastening portions that are at different distances from the second edge of the first member, the second direction of the one with the smaller distance may be directed toward the second edge rather than the one with the larger distance.

With the above configuration, the direction from the widest to the narrowest distance between the first fastening portion and the second fastening portion can be directed toward the second edge depending on the position of the first fastening portion relative to the edge of the first member. Therefore, even if there are multiple edges near the first fastening portion, an appropriate direction can be selected, efficiently bringing the second edge of the first member closer to the second member.

A display device according to Aspect 9 of the present invention is any one of Aspects 1 to 6 above, wherein the first member and the second member have a plurality of pairs of the first fastening portion and the second fastening portion, and the direction in which the spacing of the first fastening portions relative to the second fastening portions varies from a wide portion to a narrow portion depending on the position of the first fastening portions on the first member.

With the above configuration, the direction in which the spacing of the first fastening portion relative to the second fastening portion changes from wide to narrow may be different for each of the multiple first fastening portions. This makes it possible to select an appropriate direction depending on the position of the first fastening portion on the first member, efficiently bringing the edge of the first member closer to the second member.
