The embodiment of the application provides a display panel for promoting adhesion of rete and base plate and adhesion between the rete, and then make the product have the ability of anti falling. The display panel 100 includes a first substrate 110, a second substrate 120, a frame glue 130, a shielding layer 111, a first insulating layer 112, a second insulating layer 113, a planarization layer 114, and a metal film layer 115.
The present application is further described with reference to the accompanying drawings and specific examples:
specifically, referring to fig. 3 and 4, a display panel 100 is provided in the embodiment of the present application, which includes a first substrate 110 and a second substrate 120 disposed opposite to each other. And the first substrate 110 and the second substrate 120 are connected. Specifically, the display panel further includes a sealant 130, and the first substrate 110 is connected to the second substrate 120 through the sealant 130.
Referring to fig. 3, the display panel 100 includes a first insulating layer 112, a second insulating layer 113, and a planarization layer 114 disposed between the first substrate 110 and the second substrate 120. The first insulating layer 112, the second insulating layer 113, and the planarization layer 114 are sequentially stacked on the surface of the first substrate 110. That is, the first insulating layer 112 is directly disposed on a side surface of the first substrate 110 facing the second substrate 120, the second insulating layer 113 is disposed on a side surface of the first insulating layer 112 facing away from the first substrate 110, and the flat layer 114 is disposed on a side surface of the second insulating layer 113 facing away from the first insulating layer 112.
In this embodiment, a metal film layer 115 is disposed on a side of the flat layer 114 facing away from the second insulating layer 113, and the metal film layer 115 extends toward the first substrate 110 to form a plurality of metal pillars 1152 spaced apart from each other. Specifically, fig. 4 is a schematic view of the shielding layer 111 and the metal film layer 115, and fig. 4 can be regarded as a schematic view as viewed from the direction of the shielding layer 111 toward the metal film layer 115 in fig. 3. Referring to fig. 3 and 4, the metal film 115 has a plane and a plurality of metal pillars 1152 extending from the plane to one side. Since the metal film layer 115 penetrates through a plurality of film layers, it can be seen that the metal film layer 115 has a significant effect on improving adhesion between film layers and a substrate.
In this embodiment, the display panel 100 has a plurality of through holes, and the through holes penetrate through the first insulating layer 112, the second insulating layer 113 and the flat layer 114. That is, the via holes are formed in the first insulating layer 112, the second insulating layer 113, and the planarization layer 114.
The metal pillar 1152 extends to the first substrate 110 through the planarization layer 114, the second insulating layer 113, and the first insulating layer 112 in this order. It is conceivable that the metal film layer 115 is used to enhance the adhesion between the planarization layer 114, the second insulating layer 113, and the first insulating layer 112, and to enhance the adhesion between the first insulating layer 112 and the first substrate 110 by using the metal film layer 115 to pass through the through hole. That is, the through hole is used for the metal pillar 1152 to pass through, and the size of the through hole is adapted to the metal pillar 1152, preferably, the through hole just allows the metal pillar 1152 to pass through.
In an embodiment, the display panel 100 further includes a shield disposed between the first substrate 110 and the second substrate 120Layer 111 (LS layer). The shielding layer 111 is disposed on a surface of the first substrate 110 facing the second substrate 120. The shielding layer 111 is provided in the first insulating layer 112. The shielding layer 111 has holes, each metal pillar 1152 passing through the shielding layer111A corresponding hole is formed. Further, each hole is in fluid connection with a through hole such that one metal post 1152 passes through and connects to the first substrate 110.
At this time, the metal posts 1152 sequentially penetrate through the planarization layer 114, the second insulating layer 113, the first insulating layer 112, and the shielding layer 111 and then extend to the first substrate 110. It can be seen that the shielding layer 111 and the metal film layer 115 are both connected to the first substrate 110, so as to further improve the adhesion between the film layer and the first substrate 110.
In one embodiment, the shielding layer 111 is divided into a plurality of ring structures with holes. Further, the loop structures are disposed discontinuously on the surface of the first substrate 110, and ensure that the metal posts 1152 are disposed within each hole. It is conceivable that the loop-like structure resembles a ring-like structure. Preferably, the ring-shaped structure is a circular ring structure.
Alternatively, the hole shape may be circular, oval or square, so long as a ring-like structure is achieved and the metal posts 1152 can be wrapped. Preferably, the holes are circular.
The metal pillar 1152 is disposed in the hole near an end of the first substrate 110, and a size of the end of the metal pillar 1152 is adapted to a size of the hole.
In one embodiment, the first substrate 110 is a TFT glass substrate. The second substrate 120 is a CF glass substrate.
In this embodiment, in the display panel 100, there is a very complex film structure between the first substrate 110 and the second substrate 120, and the peripheral film structure of the display panel 100 is mainly shown in fig. 3. It should be understood that, in the portion of the display panel 100, which is not shown in the drawings, some other conventional structures are further included between the first substrate 110 and the second substrate 120, so as to implement the embodiments of the present application.
In one embodiment, the metal posts 1152 may be wedge-shaped structures. In other words, the through holes may be wedge-shaped structures, resembling "inverted triangular" structures. In another embodiment, the metal posts 1152 may also be cylindrical in configuration. In other words, the through hole may be cylindrical.
In an embodiment, the material of the first insulating layer 112 may be a non-metal nitride or a non-metal oxide. For example, the material of the first insulating layer 112 is silicon nitride or silicon oxide
In an embodiment, the material of the second insulating layer 113 may be a non-metal nitride or a non-metal oxide. For example, the material of the second insulating layer 113 is silicon nitride or silicon oxide.
In summary, the existing display panel may have poor adhesion of glass on the peripheral non-metal film layers and poor adhesion between the film layers, and the panel is very prone to peeling off the film layers under the action of external force. In contrast, the adhesion between the metal film 115 and the substrate of the display panel 100 provided in the embodiment of the present application is stronger than the adhesion between the non-metal film and the substrate, so that the adhesion between the film and the substrate can be significantly improved, and the adhesion between the film and the film can be improved, thereby greatly improving the anti-falling and anti-falling properties of the product.
The embodiment of the application also provides a display device, which comprises the display panel 100. In this way, the display device also has good anti-drop and anti-drop capabilities.
The foregoing has described in detail a display panel and a display device provided by embodiments of the present application, and specific examples are applied to illustrate the principles and embodiments of the present application, where the foregoing description of the embodiments is only for helping to understand the technical solution and core ideas of the present application; those of ordinary skill in the art will appreciate that: the technical scheme described in the foregoing embodiments can be modified or some technical features thereof can be replaced by equivalents; such modifications and substitutions do not depart from the spirit of the corresponding technical solutions from the scope of the technical solutions of the embodiments of the present application.
