Alternatively, the display device 1 is applied to MiniLED, microLED, electronic equipment, and the like. The display device 1 provided in this embodiment includes a package 11 for packaging the display assembly 12 to fix, seal, and protect the display assembly 12. The shape, material, and thickness of the package 11 are not limited in this application. Optionally, the material of the package 11 includes, but is not limited to, glass, polymethyl methacrylate (Polymethyl Methacrylate, PMMA), polycarbonate (PC), and the like.
The package 11 includes a body 111 and a plurality of reinforcing portions 112. In practical production, the body 111 and the reinforcing portion 112 may be integrally formed, but for convenience of understanding, the body 111 and the reinforcing portion 112 are named differently. In one embodiment, the body 111 may be understood as a flat plate, and the reinforcing portion 112 may be understood as a protrusion provided on the flat plate. The body 111 is provided with a plurality of reinforcing portions 112, and the side walls of the reinforcing portions 112 correspond to the inner walls of the housing space 11a. The body 111 corresponds to the bottom wall of the housing space 11a. It is also understood that the reinforcement portion 112 divides the package 11 into a plurality of regions, and the reinforcement portion 112 serves as a boundary of the plurality of regions. The reinforcement portion 112 has a guiding function for the splice assembly of the display module 12, and can also improve the rigidity of the package 11 and the display device 1.
The reinforcing portions 112 and the body 111 define a plurality of accommodating spaces 11a. For example, one reinforcing portion 112 is disposed on the body 111, and one accommodating space 11a is formed by enclosing one reinforcing portion 112 and the body 111, and the package 11 has two accommodating spaces 11a. For another example, a plurality of reinforcing portions 112 are disposed in an array on the main body 111, and at least two reinforcing portions 112 and the main body 111 enclose a housing space 11a. Specifically, two reinforcing portions 112 are disposed transversely, two other reinforcing portions 112 are disposed longitudinally, and two reinforcing portions 112 are disposed alternately with two other reinforcing portions 112, at this time, two arbitrary reinforcing portions 112 and the body 111 enclose one accommodating space 11a, and the package 11 has four accommodating spaces 11a.
Note that, the main body 111 corresponding to the display device 12 is the display area 11b, and at least part of the light emitted from the display device 12 can be emitted from the display area 11b to display a picture, provide information, and the like. The body 111 corresponding to the reinforcing portion 112 is a splice gap region 11c, and the splice gap region 11c corresponds to the gap between any two adjacent display modules 12, in other words, the splice gap region 11c corresponds to the splice gap between any two adjacent display modules 12.
The display device 1 provided in this embodiment further includes a plurality of display modules 12. The display component 12 is used for emitting light to display pictures, prompt messages and the like. As shown in fig. 1 and 3, in one embodiment, the display assembly 12 includes a substrate 121, a driving circuit layer 122, and at least one light emitting unit 123. The driving circuit layer 122 is disposed on a side of the substrate 121 near the body 111, and the driving circuit layer 122 is used for electrically connecting to a circuit board. And at least one light emitting unit 123 disposed on a side of the driving circuit layer 122 near the main body 111.
The display assembly 12 provided in this embodiment includes a substrate 121 for carrying other components. The shape, material, and thickness of the substrate 121 are not limited in this application. In addition, the display assembly 12 provided in this embodiment further includes a driving circuit layer 122 for electrically connecting the light emitting unit 123 with the circuit board, so as to control the display assembly 12 to emit light. The shape, material, and thickness of the driving circuit layer 122 are not limited in this application. Optionally, the circuit board is disposed on a side of the display assembly 12 facing away from the body 111.
The display assembly 12 provided in this embodiment further includes a light emitting unit 123 for emitting light to display a screen, a prompt message, and the like. The shape, material, thickness, and distribution of the light emitting unit 123 are not limited in this application. Alternatively, the light emitting unit includes, but is not limited to, an LED chip, an organic light emitting diode, and the like. Alternatively, the plurality of light emitting units 123 are disposed at intervals on one side of the driving circuit layer 122 near the body 111. Wherein, the light emitted from the display assembly 12 can pass through the package 11, i.e. the light emitted from the light emitting unit 123 can pass through the package 11. The light emitted by the display unit is shown in the direction D1 of fig. 1 and 3.
In one embodiment, the driving circuit layer 122 is connected to a side of the substrate 121 facing away from the body 111 by bending a peripheral side of the substrate 121; or the driving circuit layer 122 penetrates through the side of the substrate 121, which faces away from the body 111. It should be noted that the circuit board is not shown in fig. 1 and 3.
In one arrangement, as shown in fig. 1, the driving circuit layer 122 is connected to a side of the substrate 121 facing away from the body 111 by bending the peripheral side of the substrate 121. In other words, the driving circuit layer 122 is further disposed on the peripheral side of the substrate 121, and the driving circuit layer 122 is further disposed on a portion of the surface of the substrate 121 facing away from the main body 111, so as to electrically connect to the circuit board.
In another arrangement, as shown in fig. 3, the driving circuit layer 122 penetrates through a side of the substrate 121 facing away from the body 111. In other words, the driving circuit layer 122 penetrates from a side surface of the substrate 121 near the body 111 to a side surface of the substrate 121 far from the body 111 to electrically connect the circuit board.
Both of these arrangements can ensure that the driving circuit layer 122 is electrically connected with the circuit board, and do not affect the cooperation between the package 11 and the display assembly 12, so that the integration level of the display device 1 is improved.
Specifically, in the display device 1 provided in this embodiment, each display component 12 is correspondingly and fixedly arranged in one accommodating space 11a of the package 11, so that the plurality of display components 12 can be spliced on the package 11 and can be fixedly arranged in the accommodating space 11a of the package 11 to realize packaging. And, the light emitted by the display assembly 12 can pass through the package 11, so that the display device 1 can emit light, and the display device 1 can display images, prompt information and the like. Compared with the display device 1 in which the display assembly 12 is packaged first and then spliced and assembled in the related art, the present embodiment can simultaneously realize the splicing and packaging of the display device 1, which simplifies the structure of the display device 1, reduces the manufacturing process of the display device 1, and reduces the process difficulty in preparing the display device 1.
In this embodiment, each display module 12 is correspondingly fixed in one receiving space 11a, so that one reinforcing portion 112 is disposed between any two adjacent display modules 12, in other words, one reinforcing portion 112 is used to separate any two adjacent display modules 12. However, in the related art, the peripheral edge of each display module 12 is provided with a corresponding package structure so as to have a certain thickness, for example, the thickness of each package structure is about the thickness of one reinforcing portion 112. Therefore, the present embodiment employs one reinforcing portion 112 to separate two adjacent display modules 12, so as to reduce the splice gap between two adjacent display modules 12 and improve the display performance of the display device 1.
For example, in the related art, the periphery of each display assembly 12 has a thickness of one reinforcing portion 112, and a certain gap exists between two adjacent display assemblies 12, so the distance between any two adjacent display assemblies 12 is greater than the thickness of two reinforcing portions 112. In the present embodiment, the thickness of one reinforcing portion 112 is between any two adjacent display modules 12, so that the width of the splice gap between the display modules 12 is reduced, and the display performance of the display device 1 is improved. Also, the pitches between the display modules 12 in the related art are not equal, that is, the display modules 12 are not spliced uniformly. However, the present application improves the uniformity of display assembly stitching by employing the mounting of multiple display assemblies 12 to the enclosure 11.
In addition, the MiniLED and micro led display device 1 in the related art is limited to a chip transfer die bonding process, and the display device 1 has a smaller size and needs to be spliced to meet the requirements of practical use. However, the display device 1 has a relatively complex structure, which not only brings about a relatively remarkable splice gap, but also needs to ensure the overall stability of the display device 1. In this embodiment, each display component 12 is correspondingly and fixedly arranged in one accommodation space 11a of the packaging member 11, so that the integration of the packaging and splicing processes of the LED chips is realized, and the integrated display device 1 is formed, so that the width of the splicing gap between the display components 12 can be reduced, and the stable splicing of a plurality of display components 12 can be realized.
In one embodiment, the plurality of display modules 12 are fixedly connected to form the integrated display device 1 by using the large-sized package 11 in a manner of attaching the whole surface, so that the sealing and protecting effects on the light emitting units 123, i.e., the LED chips, in the display modules 12 can be improved. In addition, the integrated display device 1 has a better visual effect while improving the overall rigidity. The display device 1 of the present embodiment integrates packaging and splicing processes, reduces production processes, and simplifies a module structure.
Referring to fig. 4, fig. 4 is a schematic structural diagram of a display device according to another embodiment of the present disclosure. In one embodiment, the display device 1 further includes an adhesive member 13, at least part of the adhesive member 13 is adhered between the display assembly 12 and the body 111, and the light emitted from the display assembly 12 can pass through the adhesive member 13.
The display device 1 provided in this embodiment further includes an adhesive member 13 for adhering the display assembly 12 and the package member 11, so that the display assembly 12 is fixedly disposed in the accommodating space 11a of the package member 11. The material of the adhesive member 13 is not limited in this application. Alternatively, the adhesive 13 includes, but is not limited to, OCA optical cement (Optically Clear Adhesive), polyvinyl chloride (PVC) glue, black cement, and the like. The light emitted from the display assembly 12 can pass through the adhesive member 13 to illuminate the display device 1. In this embodiment, the adhesive member 13 is provided to fix the display module 12 in the housing space 11a of the package 11, which is simple and convenient, has high operability, and improves the reliability of the display device 1.
Alternatively, when the adhesive member 13 is a black glue, the thickness of the black glue between the display assembly 12 and the body 111 is thinner, so that the light emitted from the display assembly 12 can pass through the black glue. Therefore, even if the adhesive member 13 is black pepper, the light can be transmitted only by reducing the thickness to a certain extent. And, when the user looks at the display device 1, the black glue can make the user visually see that the body 111 corresponding to the display component 12 is black, thereby improving the visual effect of the user.
Optionally, a part of the adhesive member 13 is disposed on a surface of the light emitting unit 123 near the body 111, and the part of the adhesive member 13 is disposed between any two adjacent light emitting units 123 to further improve the adhesive effect.
Referring to fig. 5, fig. 5 is a schematic structural diagram of a display device according to another embodiment of the present disclosure. In one embodiment, a gap is provided between the display assembly 12 and the reinforcing portion 112, and the adhesive member 13 is further disposed within at least a portion of the gap.
The adhesive 13 is also provided in at least part of the gap. In one case, the adhesive 13 is provided at a portion of the gap. In another case, the adhesive 13 fills the gap. Alternatively, the volume ratio of the bonding member 13 provided in the gap to the gap is 60% to 100%. Specifically, the volume ratio of the adhesive member 13 provided in the gap to the gap was 70%, 80%, 90%.
In the present embodiment, the adhesive member 13 is also provided in the gap, in other words, the adhesive member 13 is filled between the main body 111 and the display unit 12, and no appearance abnormality such as air bubbles is caused, so that the adhesive member 13 can also enter the gap. Therefore, the adhesive member 13 is further disposed in the gap, so that not only the adhesive effect between the display assembly 12 and the package 11 can be further improved, but also the coating uniformity and the coating amount of the adhesive member 13 disposed between the body 111 and the display assembly 12 can be reflected, so as to facilitate the judgment of the product quality.

Fig. 11 is a partial enlarged view of fig. 10.
In one embodiment, the display assembly 12 is abutted against an inner side wall of the accommodating space 11a, the inner side wall is provided with a communication groove 113 communicating with the gap, and the adhesive member 13 disposed between the display assembly 12 and the body 111 can enter the gap through the communication groove 113.
In the present embodiment, the package 11 is further provided with a communication groove 113 for accommodating the adhesive 13 and allowing the adhesive 13 to circulate. The shape and size of the communication groove 113 are not limited in the present application. In one embodiment, the inner side wall of the accommodating space 11a refers to the side wall of the reinforcing portion 112. In another embodiment, the inner sidewall of the accommodating space 11a refers to a side of the refraction portion 114 near the display assembly 12, that is, a sidewall of the refraction portion 114. The specific arrangement of the refraction portion 114 will be described in detail below.
The communication groove 113 is provided on an inner side wall of a part of the housing space 11a. When the inner side wall of the accommodating space 11a refers to the side wall of the reinforcing portion 112, as shown in fig. 6, the display assembly 12 abuts against the side wall of the reinforcing portion 112, and the communication groove 113 is not illustrated in the sectional view of the line A-A. As shown in fig. 7 and 8, the display assembly 12 abuts against the side wall of the reinforcing portion 112, and the side wall of the reinforcing portion 112 is provided with a communication groove 113, so that the adhesive member 13 enters the gap, in other words, the adhesive member 13 is disposed between the display assembly 12 and the reinforcing portion 112.
When the inner side wall of the accommodating space 11a is referred to as a side wall of the refraction portion 114, as shown in fig. 9, the display assembly 12 is abutted against the side wall of the refraction portion 114, and the communication groove 113 is not illustrated in the cross-sectional view of the line A-A. As shown in fig. 10 and 11, the display assembly 12 abuts against the side wall of the refraction portion 114, and the side wall of the refraction portion 114 is provided with a communication groove 113, so that the adhesive member 13 enters the gap, in other words, the adhesive member 13 is disposed between the display assembly 12 and the reinforcement portion 112.
Specifically, when the display module 12 abuts against the inner side wall of the receiving space 11a, the adhesive member 13 disposed between the display module 12 and the body 111 can flow into the communication groove 113, and then flow into the gap between the display module 12 and the reinforcing portion 112 through the communication groove 113. In this embodiment, the communicating groove 113 is added to ensure that the adhesive member 13 can enter the gap, so as to determine the uniformity of coating and the amount of the adhesive member 13 disposed between the main body 111 and the display unit 12.
Referring to fig. 12, fig. 12 is a schematic structural diagram of a display device according to another embodiment of the present disclosure. In one embodiment, the surface of the reinforcing portion 112 facing away from the body 111 is closer to the body 111 than the surface of the display assembly 12 facing away from the body 111, the adhesive member 13 fills the gap, the adhesive member 13 is further disposed on the side of the reinforcing portion 112 facing away from the body 111, and the adhesive member 13 disposed on the side of the reinforcing portion 112 facing away from the body 111 can block light.
The surface of the reinforcing portion 112 on the side facing away from the body 111 is closer to the body 111 than the surface of the display assembly 12 on the side facing away from the body 111, and it is also understood that the reinforcing portion 112 is closer to the body 111 than the base of the display assembly 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 assembly 12 on the side facing away from the body 111 to the body 111. When the adhesive member 13 fills the gap, the adhesive member 13 disposed in the gap can also enter the side of the reinforcing portion 112 facing away from the body 111, so as to further enhance the adhesive effect between the display assembly 12 and the package 11.
For example, when the display device 1 includes two adjacent display modules 12 and the reinforcing portion 112 disposed between the two adjacent display modules 12, the adhesive members 13 fill the gaps between the two display modules 12 and the reinforcing portion 112, respectively, and the adhesive members 13 can also be disposed on the side of the reinforcing portion 112 away from the body 111, so that the adhesive members 13 disposed in the two gaps are connected to each other. In addition, since the thickness of the adhesive member 13 disposed on the side of the reinforcing portion 112 away from the main body 111 is relatively thick, the adhesive member 13 can block light, so that when a user looks at the display device 1, the user visually sees that the main body 111 corresponding to the reinforcing portion 112 is black, and blocks other components disposed on the side of the reinforcing portion 112 away from the main body 111, thereby improving the visual effect of the user.
Alternatively, the thickness of the adhesive member 13 provided between the display assembly 12 and the body 111 is smaller than the thickness of the adhesive member 13 provided on the side of the reinforcement portion 112 facing away from the body 111.
For example, when the adhesive member 13 is a 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 facing away from the body 111 reach a predetermined thickness. In summary, the present application can use the black glue as the adhesive 13, and control the thickness of the black glue to make the black glue between the display assembly 12 and the main body 111 have a light-transmitting effect, and make the black glue on one side of the reinforcing portion 112 away from the main body 111 have a light-shielding effect.
Referring to fig. 13, fig. 13 is a schematic structural diagram of a display device according to another embodiment of the present disclosure. In one embodiment, the package 11 further includes a light shielding layer 14, where the light shielding layer 14 is disposed on a surface of the reinforcing portion 112 facing away from the main body 111.
The package 11 of the present embodiment further includes a light shielding layer 14 for shielding a member or light. The shape, thickness, and material of the light shielding layer 14 are not limited in this embodiment. Alternatively, the light shielding layer 14 is black. In this embodiment, the light shielding layer 14 is additionally disposed on the side of the reinforcing portion 112 away from the main body 111, so that the light is shielded, and when a user looks at the display device 1, the user visually sees that the main body 111 corresponding to the reinforcing portion 112 is black, and other components disposed on the side of the reinforcing portion 112 away from the main body 111 are shielded, thereby improving the visual effect of the user.
Referring again to fig. 9, and 14-17, fig. 14 is a partially enlarged view of fig. 9, and fig. 15 is another partially enlarged view of fig. 9. Fig. 16 is a further enlarged partial view of fig. 9. Fig. 17 is a further enlarged partial view of fig. 9.
In one embodiment, the package 11 further includes a refraction portion 114, the refraction portion 114 is bent and connected between the body 111 and the reinforcement portion 112, and a portion of the light emitted from the display assembly 12 can be emitted from the body 111 directly corresponding to the reinforcement portion 112 through the refraction portion 114.
The package 11 provided in this embodiment further includes a refraction portion 114, where the refraction portion 114 is configured to eject a portion of light emitted by the display assembly 12 from the body 111 corresponding to the reinforcing portion 112. The shape and size of the refraction portion 114 are not limited in this application. The refraction portion 114 may be understood as a means for changing the propagation direction of the light, so that more light propagates toward the body 111 corresponding to the reinforcement portion 112 and is emitted from the body 111 corresponding to the reinforcement portion 112.
Alternatively, the refraction portion 114 satisfies at least one of the following: as shown in fig. 14, the refraction portion 114 is convex in a direction away from the display module 12; as shown in fig. 15, or the refracting part 114 includes a plurality of sub-refracting parts 1141, the plurality of sub-refracting parts 1141 protruding in a direction away from the display assembly 12.
As shown in fig. 16 and 17, alternatively, the refractive indexes of the sub-refractive portions 1141 are different, so that more light is emitted from the body 111 corresponding to the reinforcing portion 112.
Optionally, the widths of the plurality of sub-refracting parts 1141 are different. Further alternatively, the width of the sub-refracting part 1141 near the display assembly is greater than the width of the sub-refracting part 1141 far from the display assembly. Further alternatively, the width of the sub-refraction portion 1141 near the display assembly 12 is smaller than the width of the sub-refraction portion 1141 far from the display assembly 12, so that part of the light near the center of the axis of the display assembly 12 passes through the sub-refraction portion 1141 with a larger refractive index, and part of the light far from the center of the axis of the display assembly 12 passes through the sub-refraction portion 1141 with a smaller refractive index, so that more light is emitted from the body 111 corresponding to the reinforcing portion 112.
In this embodiment, the widths of the sub-refractive portions 1141 are set to control the refractive indexes of the sub-refractive portions 1141, so that the refractive index of the sub-refractive portion 1141 close to the display module 12 is larger, and the refractive index of the sub-refractive portion 1141 far from the display module 12 is smaller, thereby allowing more light to be emitted from the main body 111 corresponding to the reinforcing portion 112.
In this embodiment, by adding the refraction portion 114, a portion of the light emitted by the display assembly 12 can be emitted from the body 111 corresponding to the reinforcement portion 112 through the refraction portion 114, so as to increase the light emitted from the body 111 corresponding to the reinforcement portion 112, and further increase the light intensity of the body 111 corresponding to the reinforcement portion 112, that is, the light intensity of the splice gap visually seen by the user, so as to achieve the effect of further reducing the width of the splice gap visually.
Specifically, as shown in fig. 14, the light emitted from the display module 12 in the D2 direction is directly emitted through the main body 111 without passing through the refraction portion 114. The light emitted from the display assembly 12 in the direction D3 passes through the refraction portion 114 and is emitted from the main body 111 corresponding to the reinforcement portion 112.
In this embodiment, by providing the refraction portion 114 at the connection position between the package 11 and the stiffener, the light emitting unit 123 near the splice gap, that is, the large-viewing-angle light of the MiniLED chip, can be refracted through the refraction portion 114 and enter the package 11, and is emitted from the splice gap through secondary refraction, that is, the refraction angle of the light emitted by the light emitting unit 123 is increased, so that the light is emitted from the body 111 corresponding to the stiffener 112. This can reduce the difference in brightness between the splice gap and the display area 11b, and thus can further reduce the width of the splice gap visually. Note that, the display area 11b refers to the body 111 corresponding to the display module 12; the splice gap refers to the body 111 that corresponds to the reinforcing portion 112.
Optionally, referring to fig. 18, fig. 18 is a schematic structural diagram of a display device according to another embodiment of the present application. In one embodiment, the package 11 further includes at least one flexible support portion 115, the flexible support portion 115 is disposed on a sidewall of the reinforcing portion 112, the flexible support portion 115 is further away from the body 111 than the display assembly 12, and the display assembly 12 abuts against the flexible support portion 115.
The package 11 provided in this embodiment further includes a flexible supporting portion 115, which is configured to support the display assembly 12 in an abutting manner, so that the display assembly 12 is fixed in the accommodating space 11a. In the process of entering the display assembly 12 into the accommodating space 11a, the flexible supporting portion 115 is in a deformed state at this time because the flexible supporting portion 115 has flexibility, so that the display assembly 12 enters into the accommodating space 11a. When the display assembly 12 enters the accommodating space 11a and the display assembly 12 is close to the body 111 compared with the flexible supporting portion 115, the flexible supporting portion 115 is restored to be formed and abuts against the display assembly 12 to support the display assembly 12. Therefore, in the present embodiment, the flexible support portion 115 is added, so that the display module 12 can be easily and conveniently fixed in the housing space 11a, and the display module 12 can be mounted on the package 11.
