Detailed Description
For the purposes of making the objects, technical solutions and advantages of the present application more apparent, the present application will be further described in detail below with reference to the accompanying drawings.

As described in the background, the width of a seam is an important issue for tiled display devices that has been a constant concern in the industry. For a spliced display device with metal frame bending, the bending edge width can influence the width of the splice and the stability of the display panel. When the backlight source is in a high-temperature state, the backlight source can expand outwards, the display panel is mainly made of glass, the expansion amount is extremely small, and therefore the narrower the width of the bending edge of the metal frame is, the greater the risk of tripping of the display panel after the backlight source expands at high temperature is. Therefore, when the width of the folded edge is wider, the risk of tripping off the display panel can be effectively avoided, but the width of the splice is too wide, so that the display effect is affected; when the width of the folded edge is narrower, the width of the seam can be effectively reduced, the display effect is ensured, but the risk of tripping of the display panel after the backlight source expands at high temperature is increased. Therefore, in the prior art, in order to avoid the display panel from slipping off, the width of the folded edge is wider, so that the width of the splice is larger. In recent years, the spliced products with metal frame bending are continuously improved in the aspects of technology, structure, optics and the like, the continuous reduction of the widths of the spliced seams is realized, and spliced display devices with the widths of the spliced seams of 5.5mm, 3.9mm and 3.5mm are produced in a continuous mass production mode, but compared with other spliced display devices, the spliced display device with the width of 3.5mm is still a larger size. Accordingly, there is a constant effort in the industry to reduce the splice width of spliced products with metal bezel bends, but this research has not yet been further broken through due to the risk of display panel jump-out.
Based on the above-mentioned problem, this application provides a display device and splice display device, sets up elastic component 7, connects display panel 3 and glues frame 5 through elastic component 7, increases the connection fastness between display panel 3 and the gluey frame 5, so, even frame 1's the edge width that bends reduces, after backlight high temperature inflation, display panel 3 and glues frame 5 firm connection to it can not take place to jump and take place.

The connection mode between the elastic member 7 and the display panel 3 and the adhesive frame 5 may be an adhesive connection mode, a negative pressure adsorption mode, an electrostatic adsorption mode, or the like. When the elastic member 7 is bonded to the display panel 3 and the adhesive frame 5, the bonding may be performed by bonding the elastic member 7 itself to the display panel 3 and the adhesive frame 5, or by coating a layer of adhesive on the elastic member 7, and then bonding the elastic member 7 coated with the adhesive to the display panel 3 and the adhesive frame 5.

Specifically, the thickness of the light shielding foam 2 is less than or equal to the distance between the frame bending part 1-1 and the display panel 3. Further, the thickness of the light shielding foam 2 is 0.8mm or less, specifically, the thickness of the light shielding foam 2 may be 0.8mm, 0.75mm, 0.7mm, 0.5mm, or the like.

With continued reference to fig. 2, when the elastic member 7 is located on the COF (chip on film 8) side of the display device, the elastic member 7 is located between the COF and the frame body 1-2, and the elastic member 7 is connected with the COF and the adhesive frame 5, so as to ensure stable connection between the display panel 3 and the adhesive frame 5.
Referring to fig. 3, when the elastic member 7 is located on the non-COF side of the display device, the elastic member 7 is directly connected with the adhesive frame 5 to ensure a stable connection between the display panel 3 and the adhesive frame 5.
Further, referring to fig. 4, the ends of two adjacent elastic members 7 overlap. The overlapping connection mode enables the end parts of the two adjacent elastic pieces 7 to be partially overlapped, the attaching effect of the starting end of the elastic piece 7 can be improved through end part overlapping, and therefore the risk of glue opening and light leakage caused by expansion and pulling of the elastic piece 7 at high temperature of the backlight source is reduced. Specifically, the length of the overlap is 5mm or more, so that the overlap effect can be ensured. For example, the length of the overlap may be 5mm, 10mm, 15mm, etc.
In some embodiments, the elastic member 7 comprises an elastic light shielding tape.
Specifically, the elastic shading tape comprises three layers, namely a black elastic film, a PET release film and acrylic adhesive in sequence. The elastic shading tape is self-adhesive, and can be directly adhered to the display panel 3 and the rubber frame 5 when in use, so that stable connection among the elastic piece 7, the display panel 3 and the rubber frame 5 is realized. The elastic shading adhesive tape has good viscosity, shading performance and tensile breaking performance, can play a good connection role on the display panel 3 and the adhesive frame 5, can play a shielding role, avoid the leakage of backlight edge light, and meanwhile, can not easily break in the high-temperature expansion process of the backlight due to the good tensile breaking resistance, and can play a good and durable connection role to prevent the display panel 3 from tripping.
In some embodiments, to further reduce the width of the seam and further reduce the occurrence probability of the display panel 3 jumping and slit light leakage, the width of the frame bending portion 1-1 on the COF side is set to be larger than that of the frame bending portion 1-1 on the non-COF side.
Specifically, the width of the frame bending part 1-1 may be selected to be 0.9-2.5 mm, and further, the width of the frame bending part 1-1 may be selected to be 1.0-2.0 mm.
Wherein the width of the frame bending part 1-1 on the COF side can be selected to be 1.7-2.0 mm, and the width of the frame bending part 1-1 on the non-COF side can be selected to be 0.9-1.3 mm. Specifically, the width of the frame bent portion 1-1 on the COF side may be 1.7mm, 1.8mm, 1.9mm, 2.0mm, or the like, and the width of the frame bent portion 1-1 on the non-COF side may be 0.9mm, 1.0mm, 1.1mm, 1.2mm, 1.3mm, or the like.
In this embodiment, the length of the frame bent portion 1-1 on the COF side may be 1.5mm, and the length of the frame bent portion 1-1 on the non-COF side may be 0.8mm. The length dimension of the frame bending part 1-1 is far smaller than the bending edge width in the prior art, because the display panel 3 is connected with the rubber frame 5 through the elastic piece 7 in the application, the connection firmness between the display panel 3 and the rubber frame 5 is improved, and therefore, even if the bending edge width of the frame 1 is reduced, the display panel 3 cannot be tripped after the backlight source is expanded at high temperature. The metal frame bending part 1-1 width is reduced on the basis of original same-series product design, and the seam is reduced by about 20% on the basis of maintaining the product cost unchanged, and is equivalent to the seam level of a high-end product.
In some embodiments, referring to fig. 5 and 6, the frame 1 is provided with a plurality of frames; in two adjacent frames 1, a notch 1-3 is provided at a frame bending portion 1-1 of one frame 1 to accommodate the other frame bending portion 1-1 of the other frame 1.
Specifically, the frame 1 is provided with a plurality of frame bodies 1-2, and the frame bodies 1-2 of the frame 1 are sequentially connected end to end. In two adjacent frames 1, one of them frame 1 frame kink 1-1 is provided with breach 1-3, in order to hold another frame 1 frame kink 1-1 stretches into, so make two adjacent frame kink 1-1 with the distance between the display panel 3 can be the same, has promoted the planarization and the homogeneity of display device outward appearance, and compared other types of concatenation products, display device also is difficult for taking place the damage when carrying. By the design, the problem that in the prior art, the distance between two adjacent frame bending parts 1-1 and the display panel 3 is different due to the fact that the short sides of the frames 1 are pressed to form long sides is avoided, so that the appearance evenness and the picture uniformity of the whole display device are poor, and the visual effect is seriously affected is avoided.
Further, with continued reference to fig. 5 and fig. 6, the adjacent two frames 1 are respectively a first frame and a second frame, which will be described in detail. The first frame bending part of the first frame is provided with a notch 1-3 so as to accommodate the second frame bending part of the second frame to extend into the notch 1-3. Specifically, the size of the notch 1-3 is greater than or equal to the width of the second frame bending portion, so that the end portion of the frame bending portion can fully extend into the notch 1-3, and the flatness of the appearance of the whole display device is improved.
Further, the end part of the second frame bending part extends out of the second frame body and further extends into the notch 1-3, so that the connection between the first frame bending part and the second frame bending part is smooth, and meanwhile the connection between the first frame body and the second frame body is smooth.
In some embodiments, the display device further comprises: an optical film layer 4, wherein the optical film layer 4 is disposed between the first platform 51 and the display panel 3.
Specifically, the glue frame 5 further includes a second platform 52, and the height of the second platform 52 is smaller than that of the first platform 51. The second stage 52 is further provided with a diffusion plate 6, and the diffusion plate 6 is located between the second stage 52 and the optical film layer 4. Through placing the optical film layer 4 on the first platform 51, and be equipped with display panel 3 and diffuser plate 6 about it respectively, under the spacing effect of display panel 3 and diffuser plate 6, the wave perk of film layer can not appear after the expansion of optical film layer 4 under the high temperature state, also can not have the film layer fold phenomenon to take place. In particular, the optical film layer 4 may include, but is not limited to, a diffusion sheet, a prism sheet.
Further, the effective display area of the display panel 3 is located in the orthographic projection of the edge of the optical film layer 4 on the display panel 3. Thus, the edge of the optical film layer 4 is positioned outside the effective display area of the display panel 3, and the problem of bright lines at the edge can be solved.
In some embodiments, the vertex angle of the first platform 51 near the effective display area of the display panel 3 is a chamfer structure.
Specifically, if the BM (black matrix) Area of the display panel 3 is narrowed, the supporting surface of the first platform 51 of the frame 5 may enter the AA Area (Active Area), and there is a risk of darkening the edge. Therefore, the vertex angle of the first platform 51 near the effective display area of the display panel 3 is set to be a chamfer structure, so that the problem of dark frame at the edge can be avoided.
In some embodiments, referring to fig. 7, the display device further includes: a back plate 9; a plurality of light bars 10 arranged on the back plate 9; a plurality of lamp beads 10-1 are arranged on each lamp strip 10 at intervals, and the distances between at least two pairs of adjacent lamp beads 10-1 are different.
Specifically, the distances between at least two pairs of adjacent lamp beads 10-1 are different, so that the lamp beads 10-1 are distributed in a non-equidistant manner, and the picture uniformity of the display device can be improved.
Based on the same inventive concept, the application also provides a spliced display device, which is formed by splicing at least two display devices according to any one of the above.
Specifically, referring to fig. 8, the tiled display device shown in fig. 8 is tiled by four display devices as described in any of the above. Referring to fig. 9, the tiled display device shown in fig. 9 is formed by stitching two display devices according to any one of the above.
