However, with this packaging structure, the driver chip is susceptible to external signal interference, and the driver chip can also easily cause signal interference to other components on the circuit board during operation, affecting the normal use of the LED packaging unit.

[0037] This application provides a packaging structure and a display device including a plurality of such packaging structures, and by improving the packaging structure, the performance of the related products is greatly improved.
[0038] Example 1:
[0039] like Figures 1-8 As shown, this application provides a packaging structure 100, including a metal bracket 10, a driver chip 20, a light-emitting component 30, a package 40, and a metal cover plate 50.
[0040] like Figure 1 , Figure 5 and Figure 7 As shown, the metal support 10 includes a plurality of pins 11 and a first surface (e.g., facing each other) arranged opposite to each other. Figure 5 (as shown in A) and the second side (e.g.) Figure 5 (As shown in side B).
[0041] like Figure 5 and Figure 7 As shown, the driver chip 20 is disposed on the first surface of the metal bracket 10, and the driver chip 20 is used to control the light-emitting state of the light-emitting component 30. Specifically, the driver chip 20 is used to receive external electrical signals and send the control information carried by the electrical signals to the light-emitting component 30.
[0042] like Figure 5 , Figure 6 and Figure 7 As shown, the light-emitting component 30 is disposed on the second surface of the metal bracket 10 and is electrically connected to the driver chip 20 through the metal bracket 10. The driver chip 20 is used to control the light-emitting state of the light-emitting component 30, specifically including the brightness and color temperature of the light-emitting component 30.
[0043] like Figure 3 , Figure 4 and Figure 7As shown, the package 40 is disposed on the metal bracket 10. The package 40 fixes the metal bracket 10 and covers the driver chip 20 and the light-emitting component 30. Several pins 11 surround the driver chip 20 and are partially exposed outside the package 40. The pins 11 are used to receive external electrical signals and transmit the electrical signals to the driver chip 20. The electrical signals carry control information.
[0044] like Figure 3 , Figure 5 and Figure 7 As shown, the metal cover plate 50 is disposed on the side of the driver chip 20 away from the light-emitting component 30 and covers the entire surface of the driver chip 20. It can be understood that the metal cover plate 50 is a planar cover plate, and the size of the metal cover plate 50 is larger than the size of the driver chip 20. Figure 2 , Figure 3 and Figure 4 The area covered by the metal cover plate 50 is shown in the dashed box.
[0045] The packaging structure 100 provided in this application includes a metal bracket 10, a driver chip 20, a light-emitting component 30, a package 40, and a metal cover plate 50. The driver chip 20 and the light-emitting component 30 are respectively disposed on opposite sides of the metal bracket 10 and electrically connected through the metal bracket 10 to form a vertical packaging structure 100. The package 40 is used to fix the metal bracket 10 and cover the driver chip 20 and the light-emitting component 30. Several pins 11 surround the driver chip 20. The metal cover plate 50 is disposed on the side of the driver chip 20 away from the light-emitting component 30 and covers the entire surface of the driver chip 20. That is, the metal bracket 10, the several pins 11, and the metal cover plate 50 are respectively disposed on different sides of the driver chip 20, so that all six sides of the driver chip 20 can be covered by metal, and the driver chip 20 is located within the space enclosed by the metal. This improves the signal shielding capability of the packaging structure 100, reduces signal interference to the driver chip 20, and reduces signal interference generated by the driver chip 20 to external components, thereby improving the stability and reliability of the packaging structure 100.
[0046] In the embodiments provided in this application, such as Figure 1 , Figure 2 and Figure 5 As shown, the metal support 10 and the metal cover 50 are an integral structure. The first surface of the metal cover 50 faces the first surface of the metal support 10, and a receiving gap is formed between the metal cover 50 and the first surface of the metal support 10 to accommodate the driver chip 20. With this design, the package structure 100 has high integrity, the metal cover 50 is not easily detached, and manufacturing is convenient. Furthermore, as... Figure 1 , Figure 5 and Figure 7As shown, the metal bracket 10 may have a connecting portion, which extends to connect to the metal cover plate 50. The metal cover plate 50 can be used to shield the signal interference on the side of the driver chip 20 away from the light-emitting component 30, and the connecting portion can be used to shield the signal interference on the periphery of the driver chip 20, thereby effectively ensuring the anti-signal interference capability of the packaging structure 100.
[0047] In the embodiments provided in this application, the shape of the metal cover 50 is not unique. In some embodiments, such as Figure 1 As shown, the metal cover 50 has a similar shape to the main body (excluding pins 11) of the metal bracket 10, and the metal cover 50 can cover the first surface of the metal bracket 10. Alternatively, in some embodiments, such as Figure 6 and Figure 8 As shown, the size of the metal cover 50 is slightly larger than the size of the main body of the metal bracket 10, and the edge of the metal cover 50 can be bent to cover the periphery of the package 40.
[0048] In the embodiments provided in this application, the driver chip 20 and the light-emitting component 30 are welded to the metal bracket 10 and fixed by dispensing adhesive.
[0049] In the embodiments provided in this application, such as Figure 4 , Figure 5 and Figure 6 As shown, the package 40 includes an opaque first colloidal curing layer 41. The first colloidal curing layer 41 fixes the metal support 10, fills the accommodating gap between the metal cover plate 50 and the first surface of the metal support 10, and covers the driver chip 20. In this way, the first colloidal curing layer 41 can encapsulate the driver chip 20, provide physical protection for the driver chip 20, achieve insulation isolation of the driver chip 20, and support and connect the metal cover plate 50, thereby improving the safety and reliability of the package structure 100.
[0050] Furthermore, such as Figure 6 and Figure 7 As shown, the first colloidal curing layer 41 forms a receiving groove 60 on the second surface of the metal bracket 10, and the light-emitting component 30 is installed in the receiving groove 60. In this way, the sidewalls of the receiving groove 60 form a light-blocking structure, ensuring that the light beam emitted by the light-emitting component 30 can only exit from the unblocked area at the top of the receiving groove 60. This improves the light-gathering ability of the light-emitting component 30 and prevents light leakage from the bottom or sides. Furthermore, installing the light-emitting component 30 within the receiving groove 60 reduces the risk of damage to the light-emitting component 30, resulting in high reliability.
[0051] Understandable, such as Figure 6 and Figure 7 As shown, when the light-emitting component 30 is installed in the receiving groove 60, the light-emitting component 30 does not protrude from the receiving groove 60.
[0052] In the embodiments provided in this application, such as Figure 7 As shown, the encapsulation 40 includes a light-transmitting second colloidal curing layer 42, which fills the receiving groove 60 and covers the light-emitting component 30. In this way, the second colloidal curing layer 42 can encapsulate the light-emitting component 30, providing physical protection for the light-emitting component 30, achieving insulation isolation of the light-emitting component 30, and ensuring that the light beam emitted by the light-emitting component 30 can be emitted normally, thereby improving the safety and reliability of the encapsulation structure 100.
[0053] like Figure 6 The diagram shown is a schematic of the accommodating groove 60 before the second colloid curing layer 42 is filled. Figure 7 The diagram shows a second colloid curing layer 42 filled into the receiving groove 60. Figure 7 The center-point filling is a translucent second colloidal cured layer 42. It can be understood that the second colloidal cured layer 42 fills the receiving groove 60 and does not protrude from the receiving groove 60.
[0054] Furthermore, the second colloidal curing layer 42 is a light-transmitting colloidal material, specifically epoxy resin or silicone.
[0055] In the embodiments provided in this application, such as Figure 1 , Figure 4 and Figure 5 As shown, several pins 11 are exposed above the first gel-cured layer 41 and surround the outer surfaces of the first and second surfaces of the metal bracket 10. The pins 11 extend to the bottom surface of the first gel-cured layer 41 opposite to the first surface. With this design, the package structure 100 has high overall integrity and facilitates electrical connection between the pins 11 and the driver chip 20. Furthermore, the several pins 11 surrounding the sides of the driver chip 20, together with the metal bracket 10 and the metal cover plate 50, form a six-sided surrounding structure, which further enhances the signal interference immunity of the driver chip 20. In addition, the pins 11 being exposed above the first gel-cured layer 41 and extending to the bottom surface of the first gel-cured layer 41 opposite to the first surface of the metal bracket 10 provides a reasonable structure and facilitates connection with other components.
[0056] Furthermore, a portion of pin 11 is perpendicular to the first surface of metal bracket 10.
[0057] The packaging structure 100, metal bracket 10 and metal cover plate 50 provided in this application are made of copper or copper alloy.
[0058] Optionally, in the embodiments provided in this application, the metal bracket 10 and the metal cover plate 50 are made of a copper sheet. Specifically, according to design requirements, the structure of the metal bracket 10, the pin 11 and the metal cover plate 50 is etched on a copper sheet.
[0059] In the embodiments provided in this application, the light-emitting component 30 includes a plurality of light-emitting chips. Specifically, the light-emitting component 30 includes red light-emitting chips, green light-emitting chips and blue light-emitting chips. These light-emitting chips are independent of each other, and the light emission of these light-emitting chips can be controlled separately by the driver chip 20.
[0060] The packaging structure 100 provided in this application embodiment has the following specific manufacturing process: S1, a copper sheet is provided and the required pattern is made on the copper sheet to form a metal bracket 10 and a metal cover plate 50 structure, wherein the metal bracket 10 includes a plurality of pins 11 and a first side and a second side arranged opposite to each other; S2, a driver chip 20 and a light-emitting component 30 are provided, and the driver chip 20 and the light-emitting component 30 are respectively mounted on the first side and the second side of the metal bracket 10; S3, a package 40 is provided on the metal bracket 10, and the package 40 fixes the metal bracket 10 and covers the driver chip 20 and the light-emitting component 30; S4, the metal cover plate 50 is folded so that the metal cover plate 50 covers the side of the driver chip 20 away from the light-emitting component 30; S5, the pins 11 are bent so that the pins 11 surround the driver chip 20.
[0061] In summary, the packaging structure 100 provided in this application, by improving the structure of the metal support 10 and providing a metal cover plate 50 on the side of the driver chip 20 away from the light-emitting component 30, allows the driver chip 20 to be located within the space formed by the metal support 10, several pins 11, and the metal cover plate 50. This improves the signal shielding capability of the packaging structure 100, thereby enhancing its stability and reliability. Furthermore, the metal support 10 and the metal cover plate 50 of the packaging structure 100 are an integral structure, resulting in high integrity, preventing the metal cover plate 50 from easily detaching, and facilitating manufacturing.
[0062] Example 2:
[0063] like Figures 9-13 As shown, this application provides a packaging structure 100, including a metal bracket 10, a driver chip 20, a light-emitting component 30, a package 40, and a metal cover plate 50.
[0064] In the embodiments provided in this application, such as Figure 9 , Figure 10 and Figure 13 As shown, the metal support 10 includes a plurality of pins 11 and a first surface (e.g., facing each other) arranged opposite to each other. Figure 9 (as shown on one side) and the second side (e.g.) Figure 13As shown on one side), a driver chip 20 is disposed on the first side, and a light-emitting component 30 is disposed on the second side. The light-emitting component 30 is electrically connected to the driver chip 20 through a metal bracket 10. The driver chip 20 is used to control the light-emitting state of the light-emitting component 30. A package 40 is disposed on the metal bracket 10, fixing the metal bracket 10 and covering the driver chip 20 and the light-emitting component 30. Several pins 11 surround the driver chip 20 and are partially exposed outside the package 40. The pins 11 are used to receive external electrical signals and transmit the electrical signals to the driver chip 20. A metal cover plate 50 is disposed on the side of the driver chip 20 away from the light-emitting component 30 and covers the entire driver chip 20.
[0065] In the embodiments provided in this application, such as Figure 9 , Figure 10 and Figure 11 As shown, the metal bracket 10 and the metal cover plate 50 are separate structures, and the metal cover plate 50 is connected to the side of the driver chip 20 away from the light-emitting component 30. This design facilitates the installation of the driver chip 20, effectively integrates space, and helps to reduce the overall volume of the packaging structure 100, resulting in a reasonable structure.
[0066] In the embodiments provided in this application, such as Figure 9 , Figure 10 and Figure 13 As shown, the encapsulation 40 includes an opaque first colloidal curing layer 41, which fixes a metal bracket 10. A first groove 70 is formed on a first surface of the metal bracket 10, and a second groove 80 is formed on a second surface of the metal bracket 10. The driver chip 20 is installed in the first groove 70, and the light-emitting component 30 is installed in the second groove 80. The driver chip 20 and the light-emitting component 30 are respectively installed in the first groove 70 and the second groove 80, which reduces the risk of damage to the driver chip 20 and the light-emitting component 30, resulting in high reliability. Furthermore, the sidewall of the second groove 80 forms a light-blocking structure, ensuring that the light beam emitted by the light-emitting component 30 can only exit from the unblocked area at the top of the second groove 80. This improves the light-gathering ability of the light-emitting component 30 and prevents light leakage from the bottom or sides.
[0067] In the embodiments provided in this application, such as Figure 10 , Figure 12 and Figure 13As shown, the encapsulation 40 includes a light-transmitting second colloidal curing layer 42 and an insulating adhesive. The second colloidal curing layer 42 fills the second groove 80 and covers the light-emitting component 30. The metal cover plate 50 is fixed in the first groove 70 by the insulating adhesive. With this design, the second colloidal curing layer 42 can encapsulate the light-emitting component 30, providing physical protection and insulation for the light-emitting component 30, and ensuring that the light beam emitted by the light-emitting component 30 can be emitted normally, thereby improving the safety and reliability of the encapsulation structure 100. Furthermore, using the insulating adhesive to fix the metal cover plate 50 can achieve insulation isolation between the metal cover plate 50 and the driver chip 20, and can also provide physical protection for the driver chip 20.
[0068] Understandable, such as Figure 9 and Figure 10 As shown, the metal cover plate 50 is disposed in the first groove 70, and the metal cover plate 50 does not protrude from the first groove 70.
[0069] like Figure 12 The diagram shows the second groove 80 without the second colloid cured layer 42 filled. Figure 13 The diagram shows the second groove 80 filled with the second colloidal curing layer 42. Figure 13 The midpoint filler is a translucent second colloidal cured layer 42. This can be understood as... Figure 13 As shown, the light-emitting component 30 and the second colloidal curing layer 42 are disposed in the second groove 80, and the second colloidal curing layer 42 does not protrude from the second groove 80.
[0070] In the embodiments provided in this application, such as Figure 9 and Figure 13 As shown, a plurality of pins 11 extend from the first surface of the metal support 10 to the bottom surface of the first adhesive curing layer 41 opposite to the first surface, and the plurality of pins 11 surround the first groove 70. With the above design, the pins 11 do not protrude from the periphery of the first adhesive curing layer 41, do not occupy surface space, have a reasonable structure, and are easy to process and manufacture.
[0071] In the embodiments provided in this application, such as Figure 9 and Figure 13 As shown, the metal support 10 is made of etched copper blocks. A first groove 70 is formed on the first surface of the metal support 10, and a second groove 80 is formed on the second surface of the metal support 10. The encapsulation structure 100 has high support strength, is not easily deformed, and has a stable structure.
[0072] To facilitate fixing the metal cover plate 50, in the embodiments provided in this application, such as Figure 9 and Figure 10 As shown, the metal bracket 10 includes a plurality of positioning blocks 90, which are distributed around the first groove 70 and surround the metal cover plate 50.
[0073] In summary, the packaging structure 100 provided in this application, by improving the structure of the metal support 10 and providing a metal cover plate 50 on the side of the driver chip 20 away from the light-emitting component 30, allows the driver chip 20 to be located within the space formed by the metal support 10, several pins 11, and the metal cover plate 50. This improves the signal shielding capability of the packaging structure 100, thereby enhancing its operational stability and reliability. Furthermore, the metal support 10 and the metal cover plate 50 of the packaging structure 100 are separate structures, facilitating component installation and effectively integrating space, which helps to reduce the volume of the packaging structure 100, resulting in a rational structure.
