Description

[Technical Field]

[0001] The present invention relates to a display device. [Background technology]

[0002] In recent years, there has been a demand for thinner display devices, and in Patent Document 1, this is achieved by removing the bezel. In order to protect the substrate and other components attached to the chassis that provide the strength of the display device, a cover is required. From the perspective of thinner covers and better appearance, instead of a box-shaped cover covering the display panel, a structure has been adopted in which the edge of the cover is positioned at an acute angle to the display panel.

[0003] [Patent Document 1] International Publication No. WO2019 / 123871 Summary of the Invention [Problem to be solved by the invention]

[0004] However, the above-mentioned conventional technology has a problem in that the chassis and cover thermally expand due to heat generated within the display device, and the difference in thermal expansion causes the cover to warp, resulting in a gap between the edge of the cover and the chassis. The gap has drawbacks such as a decrease in appearance quality, insulation problems, and the intrusion of dust, etc. Therefore, it is common to use an additional part on the edge to seal the gap.

[0005] One aspect of the present invention aims to reduce gaps that occur at the edges of the cover. [Means for solving the problem]

[0006] In order to solve the above problem, a display device according to one embodiment 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 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. [Effects of the Invention]

[0007] According to one aspect of the present invention, gaps that occur at the edges of the cover can be reduced. [Brief explanation of the drawings]

[0009] [Embodiment 1] Hereinafter, one embodiment of the present invention will be described in detail with reference to FIGS.

[0010] (Display device configuration) 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.

[0011] 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 be an organic EL (Electro-luminescence) display panel.

[0012] The chassis 100 is a metal sheet member that maintains the strength of the display device 1. The display panel 2 and the chassis 100 are integrated by some means such as engagement, fastening, or adhesion. For example, the display panel 2 and the chassis 100 may be integrated with an adhesive or double-sided tape. Alternatively, a fixing member fixed with an adhesive may be provided on the surface of the display panel 2 opposite the surface that displays images, and the chassis 100 may be fixed to the fixing member.

[0013] The stand 3 is made of metal and resin and is used to stand the display panel 2. The stand 3 is fixed to the chassis 100.

[0014] The substrate is a circuit board that includes a circuit for generating, from an input signal, a video signal to be output to the display panel 2. The substrate is fixed to a chassis 100.

[0015] The cabinet 200 is a resin member 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 FIG. 1, the cabinet 200 covers the lower half of the chassis 100.

[0016] (Configuration of cabinet 200) Fig. 2 is a front view of the cabinet 200 according to the embodiment 1. Fig. 3 is a top view of the cabinet 200 according to the embodiment 1.

[0017] 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.

[0018] The cabinet 200 has a flat cover portion 210 that extends substantially flat near the center when viewed from the front. The cabinet 200 has curved cover portions 220 that are curved so as to protrude in an arch shape toward the front from the left and right ends of the flat cover portion 210. Furthermore, the cabinet 200 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.

[0019] Cabinet 200 is provided with a number of bosses each having a bolt hole protruding from the rear side to the front side. The bosses can be broadly classified into two types: outer edge bosses (first fastening portions) 250 located only on the outer periphery of cabinet 200 (located along the outer edge), and internal bosses 260, which are bosses other than outer edge bosses 250.

[0020] 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 has the function of bringing the outer periphery (edge 240) of the cabinet 200 as close as possible to (bringing into intimate contact with) the chassis 100 by screwing together the cabinet 200 and the chassis 100 at the outer edge boss 250.

[0021] Furthermore, bolt holes 251 (holes for fastening) are provided in outer edge boss 250, and bolt holes are provided in inner boss 260. The shapes of bolt holes 251 and the bolt holes of inner boss 260 are not limited to round holes and may be any shape. For example, in consideration of thermal expansion, elongated holes extending radially from the center of the member (cabinet 200) may be provided.

[0022] (Chassis 100 configuration) Fig. 4 is a front view of the chassis 100 according to the embodiment 1. Fig. 5 is a top view of the chassis 100 according to the embodiment 1.

[0023] The chassis 100 has a plate-like portion 110 that extends almost flat. The outer edge of the plate-like portion 110 of the chassis 100 is folded twice at 90° so that it is 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 the ears 120 using double-sided tape.

[0024] Furthermore, a large number of convex shapes are formed on the chassis 100 when viewed from the rear. Of the many convex shapes, convex portions extending in the longitudinal or lateral direction are ribs 130, which are structures for maintaining the strength of the chassis 100.

[0025] Of the many convex shapes, the convex portions facing the outer edge boss 250 and the inner boss 260 of the cabinet 200 are convex portions (second fastening portions) 140 for fastening other structural members. For example, the convex portion 140 is formed with a tap 141 (see FIG. 7) in which a burring tap is cut from the rear side to the front side. The tap 141 is a female screw provided for fastening other members to the chassis 100. The tap 141 is formed on the convex portion 140 in order to ensure a place for the screw to escape when a bolt is fastened using the tap 141.

[0026] (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. 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 when they are not fastened with screws. 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.

[0027] 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 with respect 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.

[0028] The inclined surface 252 is inclined so that it approaches the chassis 100 as it approaches the center of the cabinet 200 and moves 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 protrusion 140 in a state where it is not fastened with the screws is smaller at the center of the cabinet 200 than at the edge (edge 240) side of the cabinet 200. The parallel surface 142 and the inclined surface 252 form an angle θ that is greater than 0°. In other words, the angle θ formed by the surface of the outer edge boss 250 facing the protrusion 140 and the surface of the protrusion 140 facing the outer edge boss 250 is greater than 0°. For example, the formed angle θ is preferably 3° or greater, and approximately 5°, before being fastened with the screws.

[0029] 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 may be 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, and therefore bolt 300 can be properly fastened.

[0030] The cabinet 200 (particularly the curved cover portion 220) may warp due to the difference in thermal expansion between the chassis 100 and the cabinet 200. Therefore, even if the edge 240 is designed to have dimensions such that the edge 240 exactly abuts the chassis 100, a gap 241 may be created between the chassis 100 and the edge 240 of the cabinet 200 during use due to the warping of the cabinet 200. This gap 241 causes defects such as a deterioration in appearance, insulation problems, or the intrusion of dust or the like.

[0031] 8 is a cross-sectional view of the outer edge boss 250 according to the first embodiment when the inclined surface 252 according to the first embodiment comes into contact with the parallel surface 142. As shown in FIG. 8, the chassis 100 and the cabinet 200 are fastened to each other by a bolt 300.

[0032] By fastening the outer edge boss 250 and the protrusion 140 with a screw, the angle θ that was formed in FIG. 7 becomes smaller, and in FIG. 8, θ becomes 0 or approximately 0. As a result, a displacement occurs in the cabinet 200 in a direction that changes the angle θ formed from the outer edge boss 250 to the outside (edge 240 side). That is, for example, in FIG. 8, by fastening the outer edge boss 250 and the protrusion 140 with a screw, the edge 240 of the cabinet 200 rotates toward the chassis 100, with the outer edge boss 250 as a fulcrum. It can be said that by fastening with a screw, the cabinet 200 is deformed so that the edge 240 approaches the chassis.

[0033] That is, by screwing the outer edge boss 250 and the protrusion 140 together, the edge 240 of the cabinet 200 is brought closer to the chassis 100 (displaced in the direction from the cabinet 200 to the chassis 100 (first direction, front direction), or pressed against a member on the first direction side), and the gap 241 caused by thermal expansion, etc. is reduced or eliminated.

[0034] Note that, in terms of design (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. Therefore, gaps 241 due to warping of the cabinet 200 are unlikely to occur. Note that the edge 240 may be displaced toward the display panel 2 or pressed against the display panel 2 by fastening with screws.

[0035] Note that, in terms of design, a gap may be formed between edge portion 240 and chassis 100 when not fastened with screws. In this case, by fastening outer edge boss 250 and protrusion 140 to each other with screws, edge portion 240 comes into contact with or is slightly pressed against chassis 100. In this case, too, because cabinet 200 is deformed in advance in the direction opposite to the warpage due to fastening with screws, gap 241 due to warpage of cabinet 200 is unlikely to occur. Note that a configuration in which edge portion 240 comes into contact with or is pressed against the display panel 2 side due to fastening with screws may also be used.

[0036] (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.

[0037] 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 portion where the gap between the outer edge boss 250 and the protrusion 140 is wide to the portion where it is narrow varies depending on the position of the outer edge boss 250 relative to the edge 240.

[0038] Specifically, there are first outer edge boss 2501 and 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 is made to face 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 shorter distance has a second direction, from the widest part to the narrowest part of the spacing between the outer edge bosses 2501, 2502 and the protrusion 140 in the outer edge bosses 2501, 2502, facing the edge 242, compared to the one with the larger distance.

[0039] Although the description 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 a vertex (corner) near the edge 240. However, for the outer edge boss 250 located at a position corresponding to the center of the edge 240, the direction (vector) is perpendicular to the edge 240 because the nearby vertices are equidistant.

[0040] 9, the first outer edge boss 2501 is located at one of 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) that faces the vertex where two sides of the neighboring edge 240 intersect. Therefore, V1 faces the edge 242 more than V2.

[0041] Furthermore, the direction of the inclined surface may be determined not only based on the distance to the edge 240 but also based on, for example, 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 with respect to the chassis 100 may also be taken into consideration.

[0042] By determining the inclined surface 252 based on its positional relationship with the cabinet 200 or its positional relationship with the edge 240, it becomes easier to bring each edge 240 close to the chassis 100.

[0043] [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.

[0044] Fig. 10 is a perspective view showing the appearance of the outer edge boss 250a according to embodiment 2. Fig. 11 is a cross-sectional view showing the function of the outer edge boss 250a according to embodiment 2. As shown in Fig. 11, the chassis 100 and the cabinet 200 are stacked, and the outer edge boss 250a and the protrusion 140 face each other.

[0045] Unlike outer edge boss 250, outer edge boss 250a does not have inclined surface 252, and instead has protrusion 254. Outer edge boss 250a has protrusion 254 closer to the center of cabinet 200 than bolt hole 251, which is a hole for fastening.

[0046] Protrusion 254 and imaginary plane 252a passing through the opposite side of protrusion 254 across bolt hole 251 correspond to inclined surface 252 in embodiment 1. That is, parallel surface 142 and imaginary plane 252a form an angle θ that is greater than 0°. Furthermore, outer edge boss 250a contacts parallel surface 142 at protrusion 254, and the distance between outer edge boss 250a and convex portion 140 due to protrusion 254 is smaller on the central side of cabinet 200 than on the edge (first edge) side of cabinet 200.

[0047] 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.

[0048] In the second embodiment, it is easier to create the angle θ between the outer edge boss 250a and the protrusion 140 than in the first embodiment. Specifically, in a mold for the cabinet 200, a recess is made in a portion corresponding to the outer edge boss 250a, and the protrusion 254 can be formed by injection molding.

[0049] Furthermore, protrusion 254 may be a member that engages with outer edge boss 250a. Specifically, outer edge boss 250a may have a recess, into which a member that abuts protrusion 254 is inserted. In this case, by replacing the part of protrusion 254, the angle θ formed between parallel surface 142 and imaginary plane 252a can be changed, which has the advantage of enabling adjustment.

[0050] [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.

[0051] Fig. 12 is a perspective view showing the appearance of the outer edge boss 250b according to embodiment 3. Fig. 13 is a cross-sectional view showing the function of the outer edge boss 250b according to embodiment 3. As shown in Fig. 13, the chassis 100 and the cabinet 200 are stacked, and the outer edge boss 250b and the protrusion 140 face each other.

[0052] Unlike outer edge boss 250, outer edge boss 250b does not have inclined surface 252 formed therein. Instead, a spacer 256 having an inclined surface 252b corresponding to inclined surface 252 is added between outer edge boss 250b and protrusion 140. In other words, 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 holes or notches through which bolts pass, at positions corresponding to bolt holes 251 of outer edge boss 250b.

[0053] Spacer 256 and outer edge boss 250b are fixed at joint surface 255 with double-sided tape or the like. Joint surface 255 is the surface of spacer 256 opposite inclined surface 252b. Joint surface 255 may be parallel to parallel surface 142. In other words, the surface of outer edge boss 250b on which bolt hole 251 is formed may have a typical boss shape that is parallel to parallel surface 142.

[0054] The inclined surface 252b and the parallel surface 142 form an angle θ that is greater than 0°. 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.

[0055] 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, and the edge 240 of the cabinet 200 can be brought closer to the chassis 100.

[0056] In the third embodiment, unlike the first embodiment, the angle θ can be adjusted by replacing the spacer 256. Also, unlike the second embodiment, the screws are fastened by the surfaces, so that strong screw fastening can be achieved. Furthermore, since it is only necessary to insert the spacer 256 between the parallel surface 142 and the general outer edge boss 250b having a surface parallel to the parallel surface 142, there is also the effect of reducing the gap by retrofitting the spacer 256 in a device that was not designed to reduce the gap.

[0057] Here, spacer 256 is fixed to outer edge boss 250b, but this is not limiting and spacer 256 may be fixed to protrusion 140. The reason why spacer 256 needs to be fixed to either outer edge boss 250b or protrusion 140 is to prevent spacer 256 from rotating as bolt 300 rotates and to prevent the direction of inclined surface 252b from changing.

[0058] [Modification] In the first to third embodiments, the inclined surfaces 252, 252a, and 252b are provided on the cabinet 200 side, but the present invention is not limited to this, and the protrusion 140 of the chassis 100 may be inclined.

[0059] Furthermore, although the cabinet is made of resin and the chassis is made of metal in the above embodiment, the present invention is not limited to this. For example, the cabinet may be made of metal and the chassis may be made of resin.

[0060] Furthermore, although the direction of the inclined surface 252 is described as being 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.

[0061] 〔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, a first edge of the first member is displaced in the first direction or pressed against a member on the first direction side.

[0062] According to 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 makes it possible to prevent 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.

[0063] A display device according to aspect 2 of the present invention may be such that, in the above-mentioned aspect 1, the first fastening portion and the second fastening portion are screwed together, so that the first edge of the first member rotates toward the second member, with the first fastening portion as a fulcrum.

[0064] According to the above configuration, by screwing together the first fastening portion and the second fastening portion, the first member can be rotated using the first fastening portion as a fulcrum, and the first edge of the first member can be brought closer to the second member.

[0065] A display device according to aspect 3 of the present invention may be such that, in aspect 1 or 2 above, 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.

[0066] According to the above configuration, the distance between the first fastening portion and the second fastening portion is smaller on the central side of the first member than on the first edge side of the first member, so that by fastening with a screw, the edge of the first member can be brought closer to the second member.

[0067] A display device according to aspect 4 of the present invention, in any of aspects 1 to 3 above, may be such that 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 becomes smaller by fastening with the screw.

[0068] According to the above configuration, 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 becomes smaller by screw fastening, and the edge of the first member can be brought closer to the second member.

[0069] A display device according to a fifth aspect of the present invention is based on the first or second aspect, and the first fastening portion may include a protrusion located closer to the center of the first member than the fastening hole.

[0070] According to 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 on the center side of the first member than on the first edge side of the first member, and therefore, by fastening with a screw, the edge of the first member can be brought closer to the second member.
