Abstract

The present invention discloses a display, which includes a back plate, a cover plate, a light-transmitting plate and a light-emitting mechanism. The back plate and the light-transmitting plate form a storage cavity. The cover plate is arranged on the side of the back plate away from the light-transmitting plate. The cover plate and the back plate cooperate to form a storage space. The storage cavity and the storage space are arranged along the extension direction of the light-transmitting plate. The light-transmitting plate includes a coating layer and a transparent substrate layer that are stacked. The light-emitting mechanism is installed on the back plate, and the light emitted by the light-emitting mechanism is incident on the light-transmitting plate. Since the cover plate and the back plate form a storage space, and the storage space and the storage cavity are arranged along the extension direction of the light-transmitting plate, the electronic components of the display can be placed in the storage space, so the thickness of the display will not be increased. The light-transmitting plate composed of the coating layer and the transparent substrate layer is used, so that the light emitted by the light-emitting mechanism is incident on the light-transmitting plate, and the light can propagate in the transparent substrate layer, and then diffused by the coating layer, so that the display has uniform luminous brightness.

When the combination of technical solutions is contradictory or cannot be implemented, it should be deemed that such combination of technical solutions does not exist and is not within the scope of protection required by the present invention.

[0030] The present invention provides a display 10, such as Figure 1 and Figure 3 As shown, the display 10 includes a back plate 110, a cover plate 120, a light-transmitting plate 130 and a light-emitting mechanism 140. The back plate 110 and the light-transmitting plate 130 form a receiving cavity 111. The cover plate 120 is arranged on a side of the back plate 110 away from the light-transmitting plate 130. The cover plate 120 and the back plate 110 cooperate to form a storage space 112. The receiving cavity 111 and the storage space 112 are arranged along the extension direction of the light-transmitting plate 130. The light-transmitting plate 130 includes a coating layer 131 and a transparent substrate layer 132 that are stacked. The light-emitting mechanism 140 is installed on the back plate 110, and the light emitted by the light-emitting mechanism 140 is incident on the light-transmitting plate 130.

[0031] Among them, since the cover plate 120 and the back plate 110 form a storage space 112, and the storage space 112 and the accommodating cavity 111 are arranged along the extension direction of the light-transmitting plate 130, the electronic components 170 of the display 10 can be placed in the storage space 112, and there is no need to add an additional storage space 112 on the outside of the back plate 110 of the display 10 to place the electronic components 170 of the display 10. Therefore, the thickness of the display 10 will not be increased, which is in line with the design trend of the display 10 to be lighter and thinner. At the same time, the light-transmitting plate 130 composed of the coating layer 131 and the transparent substrate layer 132 is adopted, so that the light emitted by the light-emitting mechanism 140 is incident on the light-transmitting plate 130, the light can be transmitted in the transparent substrate layer 132, and then the light is diffused by the coating layer 131, so that the display 10 has uniform brightness. It should be noted that the storage space 112 and the accommodating cavity 111 can extend along the width direction of the display 10. When the storage space 112 extends along the width direction of the display 10, the accommodating cavity 111 is divided into two parts along the length direction of the display 10; when the storage space 112 extends along the length direction of the display 10, the accommodating cavity 111 is divided into two parts along the width direction of the display 10; according to a preferred embodiment of the present invention, the storage space 112 is close to the edge of the back panel 110 and extends along the length direction of the display 10, so that the storage space 112 can extend along the length direction of the display 10 to obtain a larger volume when the width is consistent, thereby accommodating more electronic components 170 of the display 10, which is more conducive to the lightweight design of the display 10.

[0032] Furthermore, the light-emitting mechanism 140 includes a first light-emitting component 141 and a second light-emitting component 142. The first light-emitting component 141 is located in the accommodating cavity 111 and is installed on the back panel 110. The edge of the back panel 110 is provided with a bending portion 113 bent toward the light-transmitting plate 130. The second light-emitting component 142 is installed on the side wall of the bending portion 113 facing the light-transmitting plate 130. The light emitted by the second light-emitting component 142 is incident on the light-transmitting plate 130 from the side of the light-transmitting plate 130. The second light-emitting component 142 is mounted on the bending portion 113. On the one hand, since the second light-emitting component 142 is not mounted on the back plate 110 but on the bending portion 113, the position originally reserved for mounting the second light-emitting component 142 between the back plate 110 and the light-transmitting plate 130 can be reduced, which is conducive to the thin and light design of the display 10. On the other hand, by adding the second light-emitting component 142, the light emitted by the second light-emitting component 142 can be incident into the light-transmitting plate 130 through the side of the light-transmitting plate 130, and then diffused by the coating layer 131, so that the display 10 can also obtain a relatively uniform brightness near the second light-emitting component 142. It should be noted that the second light-emitting component 142 includes a second light-emitting element 1421 and a second PCB board 1422, the second PCB board 1422 is mounted on the bending portion 113, and the second light-emitting element 1421 is mounted on the second PCB board 1422, wherein the second light-emitting element 1421 can be an LED lamp. According to an embodiment of the present invention, the side of the transparent substrate layer 132 in the light-transmitting plate 130 close to the second light-emitting component 142 is a polished surface. Figure 3 and Figure 4 As shown, the light-transmitting plate 130 includes a back side 139 close to the accommodating cavity 111 and a front side 138 away from the accommodating cavity 111. The light emitted by the first light-emitting component 141 enters from the back side 139 of the light-transmitting plate 130 and is emitted from the front side 138 of the light-transmitting plate 130. The light emitted by the second light-emitting component 142 enters from the side of the light-transmitting plate 130 close to the second light-emitting component 142 and is emitted from the front side 138 of the light-transmitting plate 130.

[0033] like Figure 2As shown, the light-transmitting plate 130 includes a first light-transmitting area 135 and a second light-transmitting area 136 connected to each other. The light emitted by the first light-emitting component 141 is incident on the first light-transmitting area 135, and the light emitted by the second light-emitting component 142 is incident on the second light-transmitting area 136. The first light-transmitting area 135 includes a transparent substrate layer 132 and coating layers 131 respectively arranged on both sides of the transparent substrate layer 132, and the second light-transmitting area 136 includes a transparent substrate layer 132 and a coating layer 131 facing the outside of the display 10. Among them, the light-transmitting plate 130 located in the first light-transmitting area 135 includes two coating layers 131 and one transparent substrate layer 132. The light emitted by the first light-emitting component 141 is first diffused by the coating layer 131 close to the first light-emitting component 141, and then diffused twice by the coating layer 131 far from the first light-emitting component 141, so that the screen brightness of the display 10 is more uniform. It should be noted that the transparent substrate layer 132 can be made of transparent materials such as PMMA (polymethyl methacrylate), PS (Polystyrene), polyacrylate organic-inorganic nanocomposite materials or optical grade glass. The coating layer 131 is mainly composed of silicon dioxide and a resin diluent or titanium dioxide and a resin diluent, and is then cured by ultraviolet or IR.

[0034] According to an embodiment of the present invention, the light-transmitting plate 130 located in the first light-transmitting area 135 may be two coating layers 131 with a transparent substrate layer 132 sandwiched therebetween, or may be one transparent substrate layer 132 and one coating layer 131 disposed toward the outside of the display 10 .

[0035] like Figure 1 and Figure 5 As shown, the display 10 further includes a reflection mechanism 150, which includes a first reflection component 151 and a second reflection component 152. The first reflection component 151 is located on the side of the first light-transmitting area 135 facing the back plate 110, and the second reflection component 152 is located on the side of the second light-transmitting area 136 facing the back plate 110. By adding the reflection mechanism 150, on the one hand, the light emitted by the first light-emitting component 141 and the second light-emitting component 142 can be more effectively reflected to the light-transmitting plate 130, so that the screen of the display 10 has a more uniform brightness; on the other hand, by adding the reflection mechanism 150, part of the light emitted from the coating layer 131 toward the direction of the back plate 110 can be effectively reflected back to the coating layer 131, thereby reducing the loss of light energy.

[0036] like Figure 1 and Figure 4As shown, one side of the second reflective component 152 abuts against the side of the second light-transmitting area 136 facing the back plate 110, and the other side of the second reflective component 152 abuts against the back plate 110. One side of the second reflective component 152 abuts against the surface of the second light-transmitting area 136 close to the back plate 110, and the other side abuts against the back plate 110, thereby achieving a distance of zero between the back plate 110 of the display 10 and the reflective sheet, which is more conducive to the slim design of the display 10.

[0037] Among them, one side of the second reflective component 152 abuts against the side of the second light-transmitting area 136 facing the back plate 110, and the other side of the second reflective component 152 is set at a preset distance from the back plate 110. The side of the second reflective component 152 away from the second light-transmitting area 136 is spaced from the back plate 110 by a certain preset distance. Since the thickness of the transparent substrate layer 132 in the light-transmitting plate 130 is usually determined according to the size of the effective display area of ​​the display 10, a certain preset distance is left between the second reflective component 152 and the back plate 110 to adapt to light-transmitting plates 130 of different thicknesses. In one embodiment of the present invention, foam is added between the back plate 110 and the second reflective component 152, and the foam not only supports the second reflective component 152, but also has a light-shielding effect. According to another embodiment of the present invention, the second reflective component 152 abuts against the back plate 110 on one side facing the back plate 110, and the second reflective component 152 abutting against the back plate 110 is at a certain distance from the light-transmitting plate 130, and the distance is typically 5 mm, 10 mm, 12 mm, 15 mm, 18 mm, 28 mm or 38 mm.

[0038] like Figure 1 and Figure 5As shown, the first light-emitting assembly 141 includes a first PCB board 1412 installed on the inner side of the back plate 110, a plurality of first light-emitting elements 1411 installed on the first PCB board 1412, and lenses 1413 respectively covered on the periphery of each first light-emitting element 1411, and the first reflective assembly 151 includes a first reflective sheet 1511, a second reflective sheet 1512, and a third reflective sheet 1514 connected in sequence, the first reflective sheet 1511 is located on the side of the accommodating cavity 111 away from the storage space 112, the second reflective sheet 1512 is installed on the first PCB board 1412, the second reflective sheet 1512 is formed with a mounting hole 1513 for the first light-emitting element 1411 to pass through, the third reflective sheet 1514 is located on the side of the accommodating cavity 111 close to the second reflective assembly 152, and the third reflective sheet 1514 is provided with a plurality of light-transmitting holes at intervals. The light emitted by the first light-emitting assembly 141 is emitted at a large angle after secondary light distribution through the lens 1413, so that the screen brightness of the display 10 is more uniform. It should be noted that the intersection of the first light-transmitting area 135 and the second light-transmitting area 136 is a brightness superposition area 137. The brightness superposition area 137 can receive not only the light emitted from the first light-emitting component 141, but also the light emitted from the second light-emitting component 142. The light emitted by the first light-emitting component 141 and the second light-emitting component 142 are superimposed in the brightness superposition area 137, so that the brightness of the brightness superposition area 137 is brighter than the brightness of other areas. By opening a plurality of light-transmitting holes in the third reflective sheet 1514, the light emitted by the first light-emitting component 141 is reduced from being reflected into the brightness superposition area 137, thereby effectively alleviating the phenomenon that the brightness superposition area 137 has a higher brightness. According to an embodiment of the present invention, the distance between the side of the light-transmitting plate 130 facing the back plate 110 and the side of the second reflective sheet 1512 facing the light-transmitting plate 130 can generally be 5mm, 10mm, 12mm, 15mm, 18mm, 28mm or 38mm.

[0039] like Figure 4As shown, the second light-transmitting region 136 further includes a light-distributing layer 133, the coating layer 131, the transparent substrate layer 132 and the light-distributing layer 133 are stacked, and a plurality of grid points 1331 are arranged at intervals on the side of the light-distributing layer 133 facing the transparent substrate layer 132, and the grid points 1331 are raised on the side of the transparent substrate layer 132. Since the light-distributing layer 133 is added to the light-transmitting plate 130 located in the second light-transmitting region 136, part of the light emitted by the second light-emitting element 1421 is transmitted through the transparent substrate layer 132 to the grid points 1331, and the grid points 1331 scatter the transmitted light, and the scattered light is then scattered again by the coating layer 131, thereby realizing the conversion of the point light source emitted by the second light-emitting element 1421 into a surface light source, and thus making the screen of the display 10 have uniform brightness. According to one embodiment of the present invention, one side of the second reflective component 152 is in contact with the light-distributing layer 133, and the other side of the second reflective component 152 is in contact with the back panel 110. Among the light emitted by the second light-emitting element 1421, part of the light is scattered by the grid dots 1331, and part of the light passes through the light-distributing layer 133 to the second reflective component 152. The second reflective component 152 reflects this part of the light again through the light-distributing layer 133, and then scatters it through the grid dots 1331 or the coating layer 131, thereby ensuring that the brightness of the display 10 is sufficient and the brightness distribution is uniform. This design does not require the use of a traditional optical film architecture, thereby simplifying the module and reducing costs.

[0040] Further, the density of the dots 1331 on the light-homogenizing layer 133 near the first light-transmitting area 135 is less than the density of the dots 1331 far from the first light-transmitting area 135. By reducing the density of the dots 1331 near the first light-transmitting area 135, the scattering of light by the dots 1331 located in the brightness superposition area 137 is effectively reduced, thereby reducing the brightness of the brightness superposition area 137, and thus making the brightness of the display 10 uniform. It should be noted that the density of the dots 1331 conforms to the preset design curve arrangement. Among them, reducing the density of the dots 1331 in the brightness superposition area 137 can be to control the distance between the dots 1331, reduce the size of the dots 1331, or control the size of the dots 1331 and increase the distance between the dots 1331.

[0041] In addition, the dots 1331 located in the brightness superposition area 137 can be set as dark dots 1331, so as to absorb part of the light energy, thereby reducing the light energy scattered by the dots 1331 located in the brightness superposition area 137, and effectively reducing the brightness of the brightness superposition area 137.

[0042] like Figure 6As shown, the thickness of the coating layer 131 near the second light-transmitting area 136 in the first light-transmitting area 135 facing the accommodating cavity 111 is greater than the thickness of the coating layer 131 far from the second light-transmitting area 136. By thickening the coating layer 131 located in the first light-transmitting area 135 and facing the back plate 110 near the second light-transmitting area 136, the diffusion effect of the light emitted by the first light-emitting element 1411 and the light reflected by the third reflective sheet 1514 is mainly increased, so that the brightness distribution of the brightness superposition area 137 is more uniform.

[0043] like Figure 1 As shown, the display 10 further includes a film 160, which is disposed on the side of the light-transmitting plate 130 away from the back plate 110. It should be noted that the film 160 may be a light-homogenizing film, which can make the brightness of the display 10 more uniform, or a light-condensing film, which can effectively improve the brightness of the display 10, wherein both the light-homogenizing film and the light-condensing film are made of existing technologies.

[0044] Among them, the back panel 110 located in the storage space 112 is provided with a positioning piece 134, wherein the positioning piece 134 can be a positioning column or a positioning protrusion. The electronic components 170 of the display 10 located in the storage space 112 can be installed on the back panel 110 of the display 10 through the positioning piece 134, thereby making the installation of the electronic components 170 more convenient.

[0045] The above are only preferred embodiments of the present invention, and are not intended to limit the patent scope of the present invention. All equivalent structural changes made using the contents of the present invention's specification and drawings, or directly / indirectly applied in other related technical fields, are included in the patent protection scope of the present invention.
