The light emitted by the display unit is shown in the D1 direction of Figure 1 and Figure 3.

In one embodiment, the driving circuit layer 122 is connected to the side of the substrate 121 away from the body 111 by bending the peripheral side of the substrate 121; or the driving circuit layer 122 penetrates the substrate 121 away from the body 111. One side of the main body 111. It should be noted that the circuit board is not shown in Figures 1 and 3 .

In one arrangement, as shown in FIG. 1 , the driving circuit layer 122 is connected to the side of the substrate 121 away from the body 111 by bending the peripheral side of the substrate 121 . In other words, the driving circuit layer 122 is also provided on the peripheral side of the substrate 121 , and the driving circuit layer 122 is also provided on a part of the surface of the substrate 121 away from the body 111 to electrically connect to the circuit board.

In another arrangement, as shown in FIG. 3 , the driving circuit layer 122 penetrates the side of the substrate 121 away from the body 111 . In other words, the driving circuit layer 122 penetrates from the side surface of the substrate 121 close to the body 111 to the side surface of the substrate 121 away from the body 111 to electrically connect the circuit board.

Both of these arrangements can ensure the electrical connection between the driving circuit layer 122 and the circuit board without affecting the cooperation between the package 11 and the display component 12 , thereby improving the integration level of the display device 1 .

Specifically, in the display device 1 provided in this embodiment, each display component 12 is correspondingly fixed in a receiving space 11a of the package 11, so that multiple display components 12 can be spliced on the package 11. It can also be fixed in the receiving space 11a of the package 11 to achieve packaging. Furthermore, the light emitted by the display component 12 can pass through the package 11 so that the display device 1 can emit light, so that the display device 1 can display images, prompt information, etc. Compared with the display device 1 in the related art where the display component 12 is first packaged and then spliced and assembled, this embodiment can realize the splicing and packaging of the display device 1 at the same time, which not only simplifies the structure of the display device 1 but also reduces the display cost. The manufacturing process of the device 1 reduces the process difficulty of manufacturing the display device 1 .

In this embodiment, each display component 12 is correspondingly fixed in a receiving space 11a, so that a reinforcing part 112 is disposed between any two adjacent display components 12. In other words, one reinforcing part 112 is used to Any two adjacent display components 12 are separated. However, in the related art, a packaging structure is provided around the periphery of each display component 12 to produce a certain thickness. For example, the thickness of each packaging structure is approximately the thickness of one reinforcing portion 112 . Therefore, this embodiment uses a reinforcing part 112 to separate two adjacent display components 12, thereby reducing the splicing gap between the two adjacent display components 12 and improving the display performance of the display device 1.

For example, in the related art, the periphery of each display component 12 has a thickness of the reinforcement 112 , and there is a certain gap between two adjacent display components 12 , so any two adjacent display components 12 The distance between them is approximately greater than the thickness of the two reinforcing parts 112 . In this embodiment, the thickness of one reinforcing portion 112 is between any two adjacent display components 12, so the width of the splicing gap between the display components 12 is reduced, and the display performance of the display device 1 is improved. Moreover, in the related art, the spacing between the display components 12 is not equal, that is, the display components 12 are spliced unevenly. However, this application improves the uniformity of splicing of display components by installing multiple display components 12 on the package 11 .

In addition, the MiniLED and MicroLED display devices 1 in the related art are limited by the chip transfer and solidification process. The display device 1 is small in size and needs to be spliced to meet the needs of actual use. However, the splicing structure of the display device 1 is relatively complex, which not only causes obvious splicing gaps, but also requires ensuring the overall stability of the display device 1. In this embodiment, by correspondingly fixing each display component 12 in a receiving space 11a of the package 11, the LED chip packaging and splicing processes are integrated to form an integrated display device 1, which can reduce the size of the LED chip. The width of the splicing gap between the display components 12 can also achieve stable splicing of multiple display components 12 .

In one embodiment, a large-sized package 11 is used to fix and splice multiple display components 12 into an integrated display device 1 by attaching the whole surface, which can improve the visibility of the light-emitting unit 123 in the display component 12 , that is, the LED. Chip sealing and protection effect. In addition, the integrated display device 1 has better visual effects and improves overall rigidity. In addition, the display device 1 of this embodiment integrates packaging and splicing processes, reducing production processes and simplifying the module structure.

Please refer to FIG. 4 , which is a schematic structural diagram of a display device provided by another embodiment of the present application. In one embodiment, the display device 1 further includes an adhesive member 13. At least part of the adhesive member 13 is bonded between the display component 12 and the body 111. The display component 12 emits light can pass through the adhesive member 13 .

The display device 1 provided in this embodiment also includes an adhesive member 13 for bonding the display component 12 and the package 11 so that the display component 12 is fixed in the receiving space 11 a of the package 11 . This application does not limit the material of the adhesive member 13 . Optionally, the adhesive member 13 includes but is not limited to OCA optical glue (Optically Clear Adhesive), polyvinyl chloride (PVC) glue, black glue, etc. The light emitted by the display component 12 can pass through the adhesive member 13 to cause the display device 1 to emit light. In this embodiment, the display component 12 is fixed in the receiving space 11 a of the package 11 by arranging the adhesive member 13 , which is simple and convenient, has high operability, and improves the reliability of the display device 1 .

Optionally, when the adhesive member 13 is made of black glue, since the thickness of the black glue between the display component 12 and the body 111 is relatively thin, the light emitted by the display component 12 can pass through the black glue. Therefore, even if the adhesive member 13 is made of black glue, light can still be transmitted as long as the thickness is thin enough. Moreover, when the user looks at the display device 1 , the black glue allows the user to visually see that the body 111 corresponding to the display component 12 is black, thereby improving the user's visual effect.

Optionally, part of the adhesive member 13 is provided on a side surface of the light-emitting unit 123 close to the body 111 , and part of the adhesive member 13 is also provided between any two adjacent light-emitting units 123 to further improve the bonding effect.

Please refer to FIG. 5 , which is a schematic structural diagram of a display device provided by another embodiment of the present application. In one embodiment, there is a gap between the display component 12 and the reinforcing part 112 , and the adhesive member 13 is also disposed in at least part of the gap.

The adhesive member 13 is also provided in at least part of the gap. In one case, the adhesive member 13 is provided in a portion of the gap. In another case, the adhesive member 13 is filled in the gap. Optionally, the volume ratio of the adhesive member 13 provided in the gap to the gap is 60%-100%. Specifically, the volume ratio of the adhesive member 13 provided in the gap to the gap is 70%, 80%, and 90%.

In this embodiment, the adhesive member 13 is also disposed in the gap. In other words, the space between the main body 111 and the display component 12 is filled with the adhesive member 13 without any abnormal appearance such as bubbles, so the adhesive member 13 can still enter the gap. Therefore, disposing the adhesive member 13 in the gap can not only further improve the bonding effect between the display component 12 and the package 11 , but also reflect the coating uniformity of the adhesive member 13 disposed between the body 111 and the display component 12 And the amount of glue applied, in order to judge the product quality.

Please refer to Figure 2 again, and refer to Figures 6 to 11. Figure 6 is a cross-sectional view along line A-A in Figure 2. FIG. 7 is a cross-sectional view along line B-B in FIG. 2 .

FIG. 11 is a partial enlarged view of FIG. 10 .

In one embodiment, the display component 12 is in contact with the inner wall of the receiving space 11a, and the inner wall is provided with a communication groove 113 that communicates with the gap, and is provided between the display component 12 and the The bonding member 13 between the bodies 111 can enter the gap through the communication groove 113 .

In this embodiment, the package 11 is also provided with a communication groove 113 for accommodating the adhesive member 13 and allowing the adhesive member 13 to circulate. This application does not limit the shape or size of the communication groove 113 . In one embodiment, the inner wall of the receiving space 11a refers to the side wall of the reinforcement part 112. In another embodiment, the inner wall of the receiving space 11a refers to the side of the refractive part 114 close to the display component 12, that is, the side wall of the refractive part 114. The specific arrangement of the refracting portion 114 will be described in detail below.

The communication groove 113 is provided on the inner wall of part of the receiving space 11a. When the inner wall of the accommodation space 11a refers to the side wall of the reinforcement part 112, as shown in FIG. 6, at this time, the display component 12 is in contact with the side wall of the reinforcement part 112. The cross-sectional view of the A-A line is not shown. Exit the communication slot 113. As shown in Figures 7 and 8, the display component 12 is in contact with the side wall of the reinforcement part 112, and the side wall of the reinforcement part 112 is provided with a communication groove 113 to allow the adhesive member 13 to enter the gap. In other words, The adhesive member 13 is disposed between the display component 12 and the reinforcement member.

When the inner wall of the accommodation space 11a refers to the side wall of the refracting part 114, as shown in FIG. 9, at this time, the display component 12 is in contact with the side wall of the refractive part 114. The cross-sectional view along the line A-A is not shown. Exit the communication slot 113. As shown in FIGS. 10 and 11 , the display component 12 is in contact with the side wall of the refractive part 114 , and the side wall of the refractive part 114 is provided with a communication groove 113 so that the adhesive member 13 can enter the gap. In other words, The adhesive member 13 is disposed between the display component 12 and the reinforcement member.

Specifically, when the display component 12 contacts the inner wall of the receiving space 11a, the adhesive member 13 provided between the display component 12 and the body 111 can flow into the communication groove 113, and then flow into the gap through the communication groove 113, that is, the display component 12 and the reinforcing part 112. Therefore, this embodiment adds a communication groove 113 to ensure that the adhesive member 13 can enter the gap, thereby determining the coating uniformity and glue amount of the adhesive member 13 provided between the body 111 and the display component 12 .

Please refer to FIG. 12 , which is a schematic structural diagram of a display device provided by another embodiment of the present application. In one embodiment, the surface of the reinforcement part 112 facing away from the body 111 is closer to the body 111 than the surface of the display component 12 facing away from the body 111 , and the adhesive member 13 The gap is filled, and the adhesive member 13 is also provided on the side of the reinforcement portion 112 away from the body 111 . The bonding member 13 is provided on the side of the reinforcement portion 112 away from the body 111 Part 13 can block light.

The surface of the reinforcement part 112 on the side away from the body 111 is closer to the body 111 than the surface of the display component 12 on the side away from the body 111. It can also be understood that the reinforcement part 112 is closer to the body 111 than the base of the display component 12; Or the distance from the surface of the reinforcing part 112 on the side facing away from the body 111 to the body 111 is smaller than the distance from the surface of the display component 12 on the side facing away from the body 111 to the body 111 . Therefore, when the adhesive member 13 fills the gap, the adhesive member 13 provided in the gap can also enter the side of the reinforcement portion 112 away from the body 111 to further improve the bonding effect between the display component 12 and the package 11 .

For example, when the display device 1 includes two adjacent display components 12 and a reinforcement part 112 disposed between the two adjacent display components 12 , the adhesive member 13 is filled with the two display components 12 and the reinforcement part 112 respectively. In the gaps between them, the adhesive member 13 can also be provided on the side of the reinforcing part 112 away from the body 111 to connect the adhesive members 13 respectively provided in the two gaps. Moreover, since the thickness of the adhesive member 13 provided on the side of the reinforcement part 112 away from the main body 111 is relatively thick, the adhesive member 13 can block light, so that when the user looks at the display device 1 , the user can visually see the reinforcement part 112 The corresponding main body 111 is black and blocks other components provided on the side of the reinforcing portion 112 away from the main body 111, thereby improving the user's visual effect.

Optionally, the thickness of the adhesive member 13 provided between the display component 12 and the body 111 is smaller than the thickness of the adhesive member 13 provided on the side of the reinforcing portion 112 away from the body 111 .

For example, when the adhesive member 13 is made of black glue, the light-shielding effect can be achieved by making the thickness of the black glue on the side of the reinforcing portion 112 away from the body 111 reach a preset thickness. To sum up, the present application can use black glue as the adhesive member 13. By controlling the thickness of the black glue, the black glue provided between the display component 12 and the body 111 has a light-transmitting effect, and the black glue provided in the reinforced part The black glue on the side of 112 facing away from the body 111 has a light-shielding effect.

In one embodiment, the package 11 further includes a light-shielding layer 14 , and the light-shielding layer 14 is provided on a surface of the reinforcing portion 112 facing away from the body 111 .

The package 11 of this embodiment also includes a light-shielding layer 14 for blocking components or light.
