Description

Technical Field

[0001] The utility model relates to the technical field of display structure, and in particular to a curved display module and a display device. Background Art

[0002] Currently, curved monitors are devices with curved edges, curving slightly toward the user for a closer fit. The curvature of the panel in curved monitors ensures an even distance between the panel and the eyes, achieving a similar viewing angle as the center of the panel, providing a wider field of view and a better viewing experience. Curved monitors are now widely acclaimed in the market and favored by many consumers, gradually becoming mainstream. They offer a great experience for gaming and watching TV in daily life. In response to market demand, various brands have begun designing competitive products, with narrow black borders, slight curvature, and ultra-wide screens becoming sought-after features. When designing a curved monitor, the overall size is determined by the size of the panel. As the black borders of the panel decrease, the overlap between the middle frame and the back panel of the curved monitor also decreases.

[0003] However, if Figure 1 As shown, the optical component 10 in the curved display includes a film 11, a light guide plate 12 and a reflective paper 13 stacked in sequence. Since the optical component 10 expands at high temperatures and contracts at low temperatures, and the bent edge 21 on the back panel 20 is perpendicular to the horizontal plane, and the side of the optical component 10 is perpendicular to the curved surface formed by the back panel 20, the gap reserved for expansion between the optical component 10 and the back panel 20, as well as the gap reserved for contraction between the optical component 10 and the middle frame 22 are very small. That is, the gap space reserved in the curved display is very small, and the expansion of the optical component 10 is limited when heated, and it will be pushed up, resulting in a poor picture on the curved display; after cooling to a low temperature, the contraction exceeds the size of the middle frame 22, and the optical component 10 will fall out. At a time when curved displays are being vigorously developed, poor quality will cause a sharp decline in brand competitiveness and increase production costs, which is not conducive to long-term development.

[0033] Below, the present invention is further described in conjunction with the accompanying drawings and specific implementation methods. It should be noted that, under the premise of no conflict, the various embodiments or technical features described below can be arbitrarily combined to form new embodiments.

[0034] See also Figure 2 As shown, the embodiment of the present invention discloses a curved display module, including a middle frame 30, a panel 40, a bending frame 50, a light source, a back plate 60 and an optical component 10. The panel 40 is an arc-shaped structure. The back plate 60 and the optical component 10 are both arc-shaped structures that match the panel 40, and their arc surfaces are basically the same. The panel 40 is fixed to the outer wall surface of the middle frame 30, and the bending frame 50 is clamped on the middle frame 30. The bending frame 50 and the middle frame 30 enclose a laterally arranged limiting groove 70. The light source is fixed in the limiting groove 70, and the back plate 60 is clamped on the bending frame 50. The middle part of the optical component 10 abuts against the back plate 60, and the side end of the optical component 10 is inserted into the limiting groove 70. The optical component 10 and the light source are arranged correspondingly at intervals, and the side end surface of the optical component 10 corresponds to its The inner side walls of the limiting groove 70 are arranged in parallel. At this time, the side end face of the optical component 10 and the inner side wall of the corresponding limiting groove 70 are perpendicular to the arc surface of the back plate 60, reserving enough gap space for the optical component 10. The gap space is the internal space of the limiting groove 70. When the temperature of the optical component 10 rises, the optical component 10 will expand due to heat in the limiting groove 70, and the optical component 10 will not be lifted up and the curved display module will not have a poor picture. When the optical component 10 is at a low temperature, the optical component 10 will shrink due to cold. Since the upper end face of the optical component 10 is limited by the middle frame 30 and the lower end face is limited by the bending frame 50, the size of the optical component 10 will not exceed the pressing range of the middle frame 30 after shrinking, and the optical component 10 will not fall out and jump out.

[0035] The back panel 60, the bending frame 50 and the middle frame 30 are assembled together. The bending frame 50 is made of plastic material. Compared with traditional curved displays, the gap space reserved for the curved display module is increased. The panel 40 includes a display area 41 and a black border 42 connected to the display area 41. The black border 42 is arranged at the edge of the panel 40 and is fixed on the middle frame 30. The projection of the black border 42 on the optical component 10 covers the projection of the middle frame 30 on the optical component 10. In the case of the same black border 42, when the optical component 10 undergoes thermal expansion effect, compared with traditional curved displays, the curved display module can greatly increase the overlapping part of the optical component 10 and the middle frame 30 in the back panel 60, and there will be no quality problems when the optical component 10 expands and contracts due to heat.

[0036] Please see further Figures 2 to 5In this embodiment, the bending frame 50 includes a side arm 51, a support assembly 52 and a first support plate 53. The support assembly 52 and the first support plate 53 are convexly arranged on the same side of the side arm 51 at intervals. The side arm 51 is clamped on the middle frame 30. The first support plate 53 is located on the side of the support assembly 52 away from the panel 40. The first support plate 53 is connected to the end of the side arm 51. The middle frame 30, the support assembly 52 and a portion of the side arm 51 enclose the aforementioned limiting groove 70. The side arm 51 and its corresponding optical component The side end surfaces of 10 are arranged in parallel, and the support assembly 52, the first support plate 53 and the other part of the side support arm 51 are enclosed to form a laterally arranged slot 54. At least one card block 61 is protruded from the bottom of the back plate 60, and the first support plate 53 is penetrated by at least one card hole 531 connected to the slot 54. The back plate 60 is inserted into the slot 54, and the number of the card blocks 61 and the card holes 531 are both multiple, and each card block 61 is respectively inserted into each card hole 531 to achieve the preliminary fixation of the back plate 60 on the bending frame 50.

[0037] It should be noted that the block 61 and the hole 531 are clearance-fitted in the direction of the arc-shaped surface of the back plate 60. When the back plate 60 is inserted into the slot 54 and the side end face of the back plate 60 is pressed against the inner side wall of its corresponding slot 54, the block 61 is located in the hole 531 and close to the inner wall of the hole 531 on the side away from the side arm 51. No pressure is required, but the block 61 cannot have a large range of motion. In the direction perpendicular to the arc-shaped surface of the back plate 60, the thickness of the back plate 60 is smaller than the width of the hole 531. When removing the back plate 60, you can directly pull outward the side end of the first support plate 53 away from the side arm 51 to withdraw the block 61 from the hole 531.

[0038] The support assembly 52 includes a second support plate 521 fixed to the side support arm 51 and a supporting ridge 522 protruding from the end of the second support plate 521 away from the side support arm 51. The supporting ridge 522 abuts against the optical component 10. The supporting ridge 522 is spaced apart from the side end surface of the optical component 10 to further increase the reserved gap space. The middle frame 30, the second support plate 521, the supporting ridge 522 and a portion of the side support arm 51 together form the aforementioned limiting groove 70. The second support plate 521, the first support plate 53 and another portion of the side support arm 51 together form the aforementioned slot 54.

[0039] After assembling the back plate 60 and the bending frame 50, the optical component 10 is assembled. Due to the curved surface, the optical component 10 will not be unable to be assembled during assembly, and it can also be well fixed. After assembling the optical component 10, the middle frame 30 is assembled to fix it in the thickness direction of the optical component 10 to prevent the optical component 10 from arching or jumping off.

[0040] Please see further Figures 1 to 4 、 Figure 6 as well as Figure 7 The side support arm 51 includes a first side plate 511 and a limit block 512. The support assembly 52 and the first support plate 53 are both vertically arranged on one side surface of the first side plate 511. The limit block 512 is protruded from the middle position of the other side surface of the first side plate 511. The first side plate 511 is perpendicular to the curved surface of the back plate 60, while the traditional bent edge 21 is perpendicular to the horizontal plane. This embodiment can solve the dilemma and poor quality of the optical component 10 that cannot be demolded when the optical component 10 is perpendicular to the curved surface of the back plate 60 and the bent edge 21 is perpendicular to the horizontal plane, resulting in problems such as the optical component 10 jumping off and bright lines.

[0041] The middle frame 30 includes a second side panel 31 and a frame body 32 perpendicularly connected to one end of the second side panel 31, and the panel 40 is fixed to the frame body 32, and a positioning groove 321 is provided on the side of the frame body 32 away from the panel 40, and the positioning groove 321 is arranged close to the second side panel 31. The second side panel 31 is penetrated by a positioning hole 311, and the first side panel 511 is located in the positioning groove 321. The width of the positioning groove 321 is greater than the width of the first side panel 511. The first side panel 511 can slide in the positioning groove 321 along the arc surface direction of the back panel 60, that is, the width direction of the positioning groove 321. The limit block 512 is located in the positioning hole 311. The width of the limit block 512 is less than the width of the positioning hole 311. The limit block 512 can slide in the positioning hole 311 along the arc surface direction perpendicular to the back panel 60, that is, the width direction of the positioning hole 311. When 511 abuts against the inner wall of the positioning groove 321 close to the second side panel 31, the limiting block 512 presses against the inner wall of the positioning hole 311 away from the panel 40, so as to realize the clamping of the bending frame 50 on the middle frame 30. The bending frame 50 does not rotate relative to the middle frame 30. The positioning groove 321 and the positioning hole 311 are required for assembly, and the bending frame 50 is made of plastic material, has a certain flexibility, and can withstand a certain range of deformation. During assembly, it is necessary to first assemble the back panel 60 on the bending frame 50, then assemble the optical component 10, and finally assemble the middle frame 30. Otherwise, the back panel 60 cannot be installed. The frame body 32, the support assembly 52 and a part of the first side panel 511 enclose the said limiting groove 70, and the support assembly 52, the first support plate 53 and another part of the first side panel 511 enclose the said slot 54.

[0042] In some embodiments, the curved display module further includes at least one fastener, the first support plate 53 is further provided with at least one through-hole 532, and the back plate 60 is provided with at least one threaded hole 62. The number of fasteners, through-holes 532 and threaded holes 62 is multiple. In order to prevent the connection strength between the back plate 60 and the bending frame 50 from being insufficient, fasteners can be used for strong fixation. The fasteners pass through the corresponding through-holes 532 and are threadedly connected to the corresponding threaded holes 62. The fasteners can be screws.

[0043] In some embodiments, the curved display module also includes a plurality of buffer cottons. A mounting groove 322 is provided on both sides of the middle frame 30. The buffer cottons are installed in the mounting groove 322. Buffer cottons are sandwiched between the panel 40 and the middle frame 30, and between the optical component 10 and the middle frame 30 to reduce the buffering force.

[0044] Please see further Figures 2 to 6 The back panel 60 includes an inserting plate 63 and a bent plate 64 that bulges toward the side close to the optical component 10. The inserting plate 63 is connected to the bent plate 64. The inserting plate 63 is inserted into the slot 54. The block 61 and the threaded hole 62 are both provided on the inserting plate 63. The middle part of the optical component 10 is connected to the bent plate 64.

[0045] In some embodiments, the back panel 60 also includes two folding edges 65, and the two folding edges 65 are both protruding from the side of the back panel 60 facing the panel 40. The two folding edges 65 are respectively located on the sky side and the ground side of the back panel 60. Each block 61 is respectively located on the left and right sides of the back panel 60, and each threaded hole 62 is also respectively located on the left and right sides of the back panel 60, which can facilitate better assembly of the back panel 60. The optical component 10 is located between the two folding edges 65, and the bending plate 64 is provided with multiple reinforcing ribs along its arc-shaped surface. The back panel 60 can be made using a stamping mold, and existing materials such as SECC, AL and SGCC can be applicable. During stamping, there is no need to set folding edges 65 on the left and right sides of the back panel 60. Only folding edges 65 are required on the sky and ground sides for attachment to the light source.

[0046] The optical component 10 includes a diaphragm 11, a light guide plate 12 and a reflective paper 13 stacked in sequence. The back plate 60 and the bending frame 50 are both connected to the reflective paper 13. The diaphragm 11 is arranged close to the panel 40, and the light source is arranged corresponding to the light guide plate 12. The light source emits light from the side of the light guide plate 12. Part of the light will propagate upward, and the other part of the light will propagate downward. The reflective paper 13 will deflect the downward light and propagate upward to form a dot matrix light. The diaphragm 11 will correct the propagation direction of the light and convert the dot matrix light into a plane array light. Finally, the light enters the panel 40, and the panel 40 is powered on to produce a picture.
