Abstract
Description
Technical Field
[0001] This invention relates to the field of display panels, and in particular to light-emitting panels and display devices. Background Technology
[0002] In the display industry, panel utilization has always been correlated with cost. Improving panel utilization can reduce costs and increase efficiency, but it usually results in scrap materials that can only be used to make small-sized feature phones or glass-based light strips.
[0003] Currently, MiniLED / MicroLED is mostly made of PCBH or FR4 material, with glass substrates being less common. The reason for this is that the yield rate of large-size glass substrate direct-lit LED panels is low, and the yield rate decreases as the size increases. If splicing can be achieved, this problem can be solved effectively. Summary of the Invention
[0004] The main technical problem solved by this application is to provide a light-emitting panel and display device that enables the splicing of large-size light-emitting panels and improves the utilization rate of small-size glass-based lamp panels.
[0005] To address the aforementioned problems, this application provides a light-emitting panel in a first aspect. The light-emitting panel includes: a carrier, comprising a base plate and side plates arranged around the base plate structure, the base plate and the side plates forming a groove; a plurality of glass-based light strips arranged side by side in the groove, each glass-based light strip having a plurality of light-emitting devices and at least one first conductive element disposed on a side surface opposite to the carrier; and a circuit board disposed on the side surface of the glass-based light strips opposite to the carrier, the circuit board having a plurality of second conductive elements disposed on a side surface facing the plurality of glass-based light strips, the plurality of second conductive elements abutting against the first conductive elements on the plurality of glass-based light strips to form a circuit connection.
[0006] Both the first conductive element and the second conductive element are magnetically conductive, and a magnetic attraction is formed between the first conductive element and the second conductive element. The plurality of glass-based light strips are aligned and connected to the circuit board through the magnetic attraction between the first conductive element and the second conductive element. One of the first conductive element and the second conductive element is a magnetic coating, and the other is a magnetic sheet.
[0007] Each glass-based lamp strip is provided with two first conductive elements, which are disposed at opposite ends of each glass-based lamp strip along a first direction; and a plurality of light-emitting devices are disposed between the two first conductive elements along the first direction.
[0008] Each glass-based light strip also includes a circuit trace connecting the first conductive element and each light-emitting device, so that the circuit board provides a light-emitting signal to the light-emitting device through the second conductive element, the first conductive element, and the circuit trace; wherein the circuit trace includes a first circuit trace and a second circuit trace, the first circuit trace connecting one of the first conductive elements and the positive terminal of each light-emitting device, and the second circuit trace connecting the other first conductive element and the negative terminal of each light-emitting device.
[0009] The depth of the groove in the carrier is not higher than the thickness of the glass-based light strip, so as to facilitate the bonding of the circuit board with the surface of the glass-based light strip; the groove in the carrier is also provided with multiple partitions, which together with the side plate form multiple limiting grooves, and the multiple limiting grooves are respectively used to place multiple glass-based light strips so that adjacent glass-based light strips are spaced apart.
[0010] The groove of the carrier is coated with a first heat dissipation coating; the side of the glass-based lamp strip where the light-emitting device is located is coated with a second heat dissipation coating.
[0011] The circuit board is provided with multiple openings, which are corresponding to the light-emitting devices on the glass-based light strip, so as to facilitate the light-emitting devices to emit light through the openings.
[0012] The surface of the circuit board facing away from the glass-based light strip is coated with a reflective coating to reflect the light emitted from the opening by the light-emitting device.
[0013] The base plate of the carrier is provided with a plurality of first positioning structures; each glass-based light strip is provided with at least one second positioning structure that cooperates with the first positioning structure on the side surface near the carrier, and the glass-based light strip is automatically installed into the corresponding position of the carrier through the cooperation of the second positioning structure and the first positioning structure.
[0014] To address the aforementioned problems, this application provides a display device in a second aspect, wherein the display device includes a light-emitting panel as described in any embodiment of the first aspect.
[0015] The beneficial effects of this application are as follows: By placing multiple small-sized glass-based light strips in the grooves of the carrier, and then setting a circuit board on the surface of the glass-based light strips to fix the multiple glass-based light strips between the circuit board and the carrier, the splicing and fixing of multiple glass-based light strips can be achieved. By assembling multiple glass-based light strips between the carrier and the circuit board to form an integral direct-lit light panel, and placing the circuit board above the glass-based light strips, a circuit is formed using magnetic attraction, thus constituting a large-sized light-emitting panel. In this way, multiple small-sized glass-based light strips can be spliced together according to the required size to obtain the desired light panel, thereby no longer being limited by size restrictions in the manufacture of glass-based light panels.

[0025] This application provides a light-emitting panel; please refer to the details. Figure 1 , Figure 1 This is a schematic diagram of the structure of an embodiment of the light-emitting panel provided in this application. Figure 1 As shown, the light-emitting panel includes a carrier 10, glass-based LED strips 20, and a circuit board 30. The carrier 10 has a groove, and multiple glass-based LED strips 20 are placed within this groove. The circuit board 30 is disposed on the surface of the glass-based LED strips 20 facing away from the carrier 10, meaning the glass-based LED strips 20 are placed within the carrier 10 and the circuit board 30. The carrier 10 and the circuit board 30 fix the multiple glass-based LED strips 20 together, thereby improving the utilization rate of the glass substrate and obtaining a large-size light-emitting panel / display panel. The circuit board 30 enables the circuit connection of the multiple glass-based LED strips 20. The circuit board 30 acts as a hub connecting the individual glass-based LED strips 20, allowing them to be connected together to form a complete light-emitting display panel. The circuit board 30 can also be connected to external circuitry, providing light emission signals to each glass-based LED strip 20.
[0026] Specifically, each glass-based light strip 20 has at least one first conductive element 22 on its surface facing the circuit board 30. The circuit board 30 is a flexible circuit board, and its surface facing the glass-based light strip 20 has multiple second conductive elements 31. These multiple second conductive elements 31 are correspondingly connected to the first conductive elements 22 on the multiple glass-based light strips 20, thereby forming a circuit connection between the circuit board 30 and the glass-based light strip 20. Specifically, the second conductive elements 31 abut against the first conductive elements 22, thereby forming a circuit connection between the circuit board 30 and the glass-based light strip 20 through the second conductive elements 31 and the first conductive elements 22.
[0027] In this embodiment, both the first conductive element 22 and the second conductive element 31 are magnetically conductive. That is, the first conductive element 22 and the second conductive element 31 possess both electrical conductivity and magnetic permeability. The electrical conductivity enables signal connection between the circuit board 30 and the multiple glass-based LED strips 20, while the magnetic permeability enables alignment between the circuit board 30 and the multiple glass-based LED strips 20. Magnetic permeability refers to the magnetic attraction between the first conductive element 22 and the second conductive element 31. The multiple glass-based LED strips 20 are aligned with the circuit board 30 through this magnetic attraction, meaning they are connected to corresponding positions on the circuit board 30. On one hand, the first conductive element 22 and the second conductive element 31 align the multiple glass-based LED strips 20 one-to-one onto the circuit board 30; on the other hand, the circuit board 30 is fixed to the surface of the multiple glass-based LED strips 20.
[0028] In some embodiments, one of the first conductive element 22 and the second conductive element 31 is a magnetic coating, and the other is a magnetic sheet. Specifically, the first conductive element 22 is a magnetic coating applied to the surface of the glass substrate of the glass-based light strip 20, and the second conductive element 31 is a magnetic sheet disposed on the circuit board 30.
[0029] In some embodiments, the first conductive element 22 and the second conductive element 31 include two or more materials selected from iron, silver, gold, and copper.
[0030] In this embodiment, a plurality of light-emitting devices 21 are disposed on the glass-based light strip 20, including LEDs, etc. The side of the glass-based light strip 20 with the light-emitting devices 21 is placed in the groove 101 facing away from the support member 10, so that the light-emitting devices 21 are positioned towards the circuit board 30. The light-emitting devices 21 may protrude from the surface of the glass-based light strip 20 and extend towards the circuit board 30. In this specific embodiment, the light-emitting devices 21 may extend beyond the circuit board 30; in other embodiments, they may not extend beyond the surface of the circuit board 30, and this is not limited here.
[0031] Please refer to further details. Figure 2 , Figure 2 This is a top view structural diagram of a specific embodiment of the glass-based light strip provided in this application. Figure 2As shown, the glass-based light strip 20 includes a transparent glass substrate, a plurality of light-emitting devices 21 disposed on the glass substrate, and at least one first conductive element 22. Further, the glass-based light strip 20 is also provided with circuit traces 23, which connect the first conductive element 21 and each light-emitting device 21, thereby allowing the circuit board 30 to transmit light emission signals to the glass-based light strip 20 via the first conductive element 22, and then to each light-emitting device 21 via the circuit traces 23, so that each light-emitting device 21 emits light. The circuit traces 23 can be disposed in the inner layer of the glass substrate or on the surface of the glass substrate. In one embodiment, two first conductive elements 22 are included, respectively disposed at opposite ends of each glass substrate along a first direction. The plurality of light-emitting devices 21 are arranged side-by-side along the first direction. The circuit traces 23 also include two traces, specifically a first circuit trace and a second circuit trace. The first circuit trace connects one of the first conductive elements 22 to the positive terminal of each light-emitting device 21, and the second circuit trace connects the other second conductive element 22 to the negative terminal of each light-emitting device 21, thereby providing a light-emitting signal to the light-emitting device 21 through the two first conductive elements 22 and the two circuit traces 23. In another embodiment, the first conductive element 22 may include one, and the circuit trace 23 may also include one, grounding the negative terminal (or one of the electrodes) of the light-emitting device 21. Light emission can also be achieved by providing a voltage signal for light emission to the positive terminal of the light-emitting device 21 through one first conductive element 22 and the circuit trace 23. In other embodiments, the first conductive element 22 may include three or more, which is not limited here. In this embodiment, the first conductive element 22 also has magnetic properties and a positioning function. Multiple first conductive elements 22 are aligned and connected to the circuit board 30, which can fix the glass-based lamp panel 20 at the corresponding position on the circuit board 30.
[0032] In some embodiments, the first conductive element 22 may protrude from the surface of the glass-based lamp strip 20 and extend toward the circuit board 30, specifically extending to abut against the second conductive element 31 on the circuit board 30. The second conductive element 31 on the circuit board 30 also has conductive properties, thereby enabling the transmission of electrical signals to the light-emitting device 21 on the glass-based lamp strip 20 through the first conductive element 22 and the circuit trace 23. The first conductive element 22 protrudes from the surface of the glass-based lamp strip 20 to form a pin, which has both conductive and magnetic properties.
[0033] In one specific embodiment, each glass-based light strip 20 is provided with at least two first conductive elements 22. The two first conductive elements 22 are preferably provided at the two opposite edges (ends) of the glass-based light strip 20, so as to fix the glass-based light strip 20 to the circuit board 30 by means of the two first conductive elements 22.
[0034] In one specific embodiment, preferably, the circuit board 30 can be a flexible printed circuit board (FPC), which allows for a certain degree of bending. In other embodiments, the circuit board 30 can also be a printed circuit board, and this is not limited thereto.
[0035] Please refer to further details. Figure 3 , Figure 3 This is a schematic diagram of a specific embodiment of the circuit board provided in this application. Figure 3 As shown, the surface of the circuit board 30 facing the glass-based light strip 20 is provided with a plurality of second conductive elements 31 corresponding to the first conductive element 22. The second conductive elements 31 can be made of a silver / copper plated magnetic material. Specifically, a layer of conductive material (such as silver, copper, gold, etc.) is electroplated onto the surface of the magnetic material, thus giving the second conductive element 31 both magnetic and electrical properties. It should be noted that the materials of the second conductive elements 31 and the first conductive elements 22 can be the same or different, and this is not limited here.
[0036] In a further embodiment, to ensure automated assembly of the glass-based light strips 20 and the circuit board 30, a second conductive element 31 can be provided at a corresponding position on the circuit board 30 and each glass-based light strip 20 where a first conductive element 22 is provided. When the circuit board 30 approaches the glass-based light strips 20, the first conductive element 22 and the second conductive element 31 automatically align and fix the circuit board 30 to the multiple glass-based light strips 20. On the other hand, the multiple glass-based light strips 20 located between the carrier 10 and the circuit board 30 can also be automatically aligned and arranged. In particular, when there is a gap between the glass-based light strips 20, the alignment between the first conductive element 22 and the second conductive element 31 can prevent the glass-based light strips 20 from being placed at an angle.
[0037] Furthermore, the circuit board 30 is also provided with an opening 32 for allowing light from multiple light-emitting devices 21 on the glass-based light strip 20 to pass through the opening 32 and emit light outwards. In this specific embodiment, there are multiple openings 32, each corresponding to one light-emitting device 21. Preferably, the size of the opening 32 can be larger than the size of the light-emitting device 21 to facilitate the light-emitting device 21 extending outwards (towards the display panel) through the opening 32. In one embodiment, the height of the light-emitting device 21 protruding from the surface of the glass-based light strip 20 can be greater than the thickness of the circuit board 30, so that the light-emitting device 21 extends outwards through the opening 32 to form the light-emitting surface of the light-emitting panel. The shape of the opening 32 is adapted to the shape of the light-emitting device 21. In one embodiment, the opening 32 can be a square opening or a circular opening on the projection plane perpendicular to the glass-based light strip 20, which is not limited here. In other embodiments, one opening 32 can also correspond to multiple light-emitting devices 21, so that multiple light-emitting devices 21 emit light through the opening 32. In other embodiments, the light-emitting device 21 may not protrude from the surface of the glass-based light strip 20 and / or the surface of the circuit board 30.
[0038] Furthermore, a reflective coating 301 is applied to the surface of the circuit board 30 facing away from the glass-based light strip 20. Preferably, the reflective coating 301 is a white coating used to reflect light refracted back by the display panel, thereby improving the overall brightness of the display panel. Preferably, the thickness of the circuit board 30 is 0.1~0.5mm, and the thickness of the reflective coating 301 is approximately 0.05~0.2mm. Ideally, the thickness of the reflective coating 301 accounts for 20~50% of the total thickness of the circuit board 30. The thickness of the circuit board 30 does not exceed the height of the light-emitting device 21.
[0039] In this embodiment, the support member 10 is specifically used to support multiple glass-based light strips 20. In one specific embodiment, the support member 10 includes a base plate 11 and a side plate 12, the side plate 12 being arranged around the base plate 11 and perpendicular to the base plate 11. The base plate 11 and the side plate 12 form a groove 101, thereby facilitating the placement of multiple glass-based light strips 20 in the groove 101, and restricting the glass-based light strips 20 through the groove 101. For details, please refer to [reference needed]. Figure 4 , Figure 4 This is a top view of a first specific embodiment of the support member provided in this application. The base plate 11 has a square (rectangular / square) structure, and four side plates 12 are arranged around the base plate 11. In other embodiments, the support member 10 may only include the base plate structure 11, which is not limited here.
[0040] Further, please refer to Figure 5 , Figure 5 This is a top view of a second specific embodiment of the carrier provided in this application. Figure 5 As shown, the carrier 10 includes a base plate 11 and side plates 12, as well as a plurality of partitions 13 disposed within a groove 101. The partitions 13 are perpendicular to the base plate 11 and parallel to two of the side plates 12. Specifically, the partitions 13 and the side plates 12 form a plurality of limiting grooves 102 that are similar in shape and size to the glass-based light strips 10. The plurality of glass-based light strips 20 are respectively placed in each limiting groove 102 and separated from each other by the partitions 13, thereby avoiding damage caused by direct contact between adjacent glass-based light strips during assembly and improving assembly stability.
[0041] In some embodiments, the side plate 12 of the carrier 10 may also be provided with fixing holes or fixing members for fixed connection with the circuit board 30, which is not specifically limited here.
[0042] In some embodiments, the glass-based light strip 20 is a strip-shaped, light-emitting glass-based light strip formed by fabricating light-emitting devices on the scrap material of a glass substrate. The limiting groove 102 is similar in shape to the glass-based light strip 20, and is also a rectangular groove. The size of the limiting groove 102 is slightly larger than that of the glass-based light strip 20 to accommodate each glass-based light strip 20.
[0043] More preferably, the depth of the groove 101 formed in the carrier 10 is not greater than the thickness of the glass-based light strip 20, so that the circuit board 30 is fitted to the surface of the glass-based light strip 20. This also facilitates the contact between the first conductive element 22 on the glass-based light strip 20 and the second conductive element 31 on the circuit board 30. Preferably, the depth of the groove 101 is the same as the thickness of the glass-based light strip 20. In another embodiment, the depth of the groove 101 may be less than the thickness of the glass-based light strip 20. The circuit board 30 is a flexible circuit board, and the area of the circuit board 30 is larger than the area of multiple glass-based light strips 20 spliced together. The portion of the circuit board 30 larger than the glass-based light strip 20 bends towards the carrier 10 and abuts against the side plate 12 of the carrier 10, and is then fixed by a fastener.
[0044] Furthermore, a first positioning structure 111 is provided on the base plate 11 of the support member 10, for details please refer to Figure 6 , Figure 6This is a schematic diagram of the structure of an embodiment of the carrier and glass-based light strip provided in this application. A plurality of first positioning structures 111 are provided on the surface of the base plate 11 near the glass-based light strip 20, that is, multiple first positioning structures 111 are provided in the groove 101 or each limiting groove 102. Each glass-based light strip 20 also has at least one second positioning structure 201 that cooperates with the first positioning structure 111 on its side surface near the carrier 30. The first positioning structure 111 and the second positioning structure 201 are connected relative to each other. In one embodiment, one of the first positioning structure 111 and the other positioning structure 201 can be a boss and the other a groove of the same shape. Each glass-based light strip 20 is automatically installed onto the corresponding position on the base plate 11 of the carrier 10 through the relative positioning of at least one second positioning structure 201 with the first positioning structure 111. In other embodiments, the first positioning structure 111 and the second positioning structure 201 can have a structure with mutual magnetic attraction, similar to the first conductive element 22 and the second conductive element 31, and are not limited here. In one embodiment, the boss and the groove can be triangular, square, or other shapes, etc., and are not limited thereto. The size of the groove is slightly larger than the size of the boss to facilitate the accommodation of the boss. In a preferred embodiment, each glass-based light strip 20 has two second positioning structures 201 on its bottom surface. The second positioning structures 201 are located at two opposite corners, so that each glass-based light strip 20 can be fixed to the corresponding position on the base plate 11 by the two second positioning structures 201. In other embodiments, each glass-based light strip 20 can have more than two second positioning structures 201, or it can have only one second positioning structure 201. However, the positioning effect of only one second positioning structure 201 is not as good as that of two second positioning structures 201. In a preferred embodiment, two second positioning structures 201 are symmetrically arranged along the central axis of the glass-based light strip 20, two first conductive elements 22 are also symmetrically arranged along the central axis of the glass-based light strip 20, and two circuit lines 23 are also symmetrically arranged along the central axis of the glass-based light strip 20. This ensures that regardless of whether the glass-based light strip 20 is placed in the groove 101 or the limiting groove 102, the positions of the two first conductive elements 22 and the two circuit lines 23 on the front side of the glass-based light strip 20 relative to the circuit board 30 remain unchanged. It should be noted that the front side of the glass-based light strip 20 refers to the surface of the glass-based light strip 20 facing the circuit board 30, and the bottom or back side of the glass-based light strip 20 refers to the surface of the glass-based light strip 20 facing the base plate 11.
[0045] In a further embodiment, the side plate 12 of the carrier 10 facing the circuit board 30 has multiple fixing holes (such as screw holes 121). The circuit board 30 also has through holes 33 at positions corresponding to the screw holes 121. The circuit board 30 is fixedly connected to the carrier 10 through the through holes 33 and screw holes 121 by a fixing member 40, that is, the circuit board 30 is fixed to the carrier 10 by the fixing member 40, thereby fixing multiple glass-based light strips 20 between the circuit board 30 and the carrier 10. The fixing member 40 can be a bolt, screw, or rivet, etc., and is not limited here. In other embodiments, the fixing member 40 may not be provided. Specifically, the circuit board 30 and the glass-based light strips 20 can be fixed by the first conductive member 22 and the second conductive member 31, and the glass-based light strips 20 and the carrier 10 can be fixed by the second positioning structure 201 on the back of the glass-based light strips 20, thereby achieving the fixation of the three, which is not limited here.
[0046] The via 33 is a circular hole on the projection plane perpendicular to the glass-based light strip 20, so that the fastener 40 can pass through the through-hole 33. The size (diameter) of the via 33 is larger than the size of the portion of the fastener 40 that passes through the via 33 (stud portion), and smaller than the size of the portion of the fastener 40 that is disposed on the surface of the circuit board 30 away from the glass-based light strip 20 (nut portion).
[0047] It should be noted that the circuit board 30 is fixedly connected to the carrier 10 through the fastener 40 on the one hand, and fixedly connected to the glass-based light strip 20 through the second conductive element 31 on the other hand.
[0048] The carrier component 10 can be made of metal, such as SGCC, SECC, aluminum alloy, etc., or plastic, such as PMMA, PC, PET, etc., without limitation. Preferably, a metal component is used, as it improves the heat dissipation performance of the glass-based light strip 20.
[0049] In a preferred embodiment, a first heat dissipation coating, such as thermal grease, can be pre-applied in the groove 101 of the carrier 10 before the glass-based lamp strip 20 is placed in, thereby improving the overall heat dissipation effect of the display device and improving the reliability of the display device.
[0050] In a preferred embodiment, a second heat-dissipating coating is applied to the front surface of the glass-based lamp strip 20.

[0052] The beneficial effects of this application are as follows: By placing multiple small-sized glass-based light strips in the grooves of the carrier, and then setting a circuit board on the surface of the glass-based light strips to fix the multiple glass-based light strips between the circuit board and the carrier, the splicing and fixing of multiple glass-based light strips can be achieved. By assembling multiple glass-based light strips between the carrier and the circuit board to form an integral direct-lit light panel, and placing the circuit board above the glass-based light strips, a circuit is formed using magnetic attraction characteristics, thus constituting a large-sized light-emitting panel. In this way, multiple small-sized glass-based light strips can be spliced together according to the required size to obtain the required light panel, thereby no longer being limited by size restrictions in the production of glass-based light panels. Moreover, the production of a single glass-based light strip is simple, has a high yield, and low production cost, which has great significance for expanding the application of MiniLED (small-size light-emitting diode) and MicroLED (submillimeter light-emitting diode).
