Detailed Description
In the prior art, in order to improve the screen occupation ratio of the display device, the AA area of the display module is dug to form a hole for accommodating the camera, however, the arrangement of the hole brings about a new problem when the screen occupation ratio of the display device is improved. The evaporation coating functional layer is formed by evaporation coating on the whole surface, the accommodating holes are formed by cutting, water vapor and oxygen in the environment easily permeate into the display panel from the hole walls of the accommodating holes through the evaporation coating functional layer, and in order to solve the problem, the currently adopted mode is to separate the evaporation coating functional layer so as to cut off permeation paths of the water vapor and the oxygen. However, while this approach cuts off the moisture and oxygen permeation path, the partitions are prone to package failure when the film is packaged, which also adversely affects the display panel.
The embodiment of the invention provides a display panel and a display device, and aims to solve the problem that packaging failure is easily caused at a partition part when a thin film is packaged after the evaporation functional layer is partitioned in the prior art.

The display panel 100 includes: a substrate 10; the evaporation coating functional layer 20 is positioned on one side of the substrate 10, the non-display area NA comprises a partition area D surrounding the accommodating hole 1, and the partition area D comprises at least one partition groove 30 surrounding the accommodating hole 1; the evaporation function layer 20 includes a first evaporation function layer 201 and a second evaporation function layer 202, the first evaporation function layer 201 is located at the bottom of the partition groove 30, and the first evaporation function layer 201 is not connected to the second evaporation function layer 202. Referring to fig. 3, fig. 3 is a schematic view of a portion of the enlarged structure at H in fig. 2. As shown in fig. 3, the partition groove 30 includes a first sidewall 301 and a second sidewall 302 oppositely disposed, and the first sidewall 301 is located on a side of the second sidewall 302 close to the display area AA; the display panel 100 further includes: the thin film packaging layer 40 is positioned on one side of the evaporation function layer 20, which is far away from the substrate 10; the first metal layer 50 is located on a side of the film encapsulation layer 40 away from the evaporation functional layer 20, the first metal layer 50 includes a first metal encapsulation portion 501, the first metal encapsulation portion 501 at least covers the first sidewall 301 of the partition groove 30, and extends from the first sidewall 301 of the partition groove 30 to the bottom of the partition groove 30, that is, the first metal encapsulation portion 501 at least covers a part of the bottom of the partition groove 30 and the whole first sidewall 301.
In the film forming process of the inorganic layer, the partition groove has a special shape, and the section difference between the side wall of the partition groove and the bottom of the partition groove is large and is a weak point in the packaging process of the thin film packaging layer 40; because of the problem of film forming process, the package failure is easily generated at the side wall of the partition groove 30 and the joint of the side wall and the bottom of the partition groove.
Optionally, with continued reference to fig. 2, an orthographic projection of the thin film encapsulation layer 40 on the substrate 10 covers the isolation groove 30, and the first metal encapsulation portion 501 is in direct contact with the thin film encapsulation layer 40.

Further, the distance between the first sidewall 301 and the second sidewall 302 is gradually reduced along the direction of the substrate 10 pointing to the evaporation coating functional layer 20, and there is no sudden change, which is beneficial to uniform packaging of the thin film packaging layer 40 and the first metal layer 50 and the second metal layer, and is beneficial to achieving a better packaging effect, and reducing the possibility of water vapor and oxygen permeation.

The display panel is encapsulated by a thin film in which inorganic layers and organic layers are sequentially stacked, and Ink-jet printing (Ink-jet Printer) is one of the common processes for preparing organic layers, and the dam 90 is designed to allow Ink material to be printed in a designated area. In one embodiment, the cross-sectional shape of the retaining wall 90 may be trapezoidal, and the end of the retaining wall with the larger size is close to the substrate 10.

Referring to fig. 4 and 5, fig. 5 is a schematic structural diagram of a touch electrode and a containing hole in an embodiment of the invention. The display panel 100 further includes an insulating layer 60 disposed on a side of the first metal layer 50 away from the film encapsulation layer 40, and a touch electrode layer 70 disposed on a side of the insulating layer 60 away from the first metal layer 50, where the touch electrode layer 70 includes a plurality of first touch electrodes 710 and a plurality of second touch electrodes 720, the first touch electrodes 710 extend along a first direction X and are arranged along a second direction Y, the second direction Y intersects the first direction X, the first touch electrodes 710 include two first sub-touch electrodes 711/712 located on two opposite sides of the accommodating hole 1 in the first direction X, that is, the first touch electrodes 710 include a first sub-touch electrode 711 located on one side of the accommodating hole 1 in the first direction and a first sub-touch electrode 712 located on the other side of the accommodating hole 1 in the first direction.

With reference to fig. 5, in an alternative embodiment, the first touch electrode 710 and the second touch electrode 720 are disposed on the same layer, and the accommodating hole 1 occupies one electrode block of the first touch electrode 710, at this time, the two first sub-touch electrodes 711/712 may be electrically connected through the first metal encapsulation portion 501; of course, in other implementation manners, the accommodating hole may also occupy one electrode block of the second touch electrode 720, and at this time, the two second sub-touch electrodes may be electrically connected through the first metal encapsulation portion. In the two arrangements, an additional layer for connecting the two first sub-touch electrodes or the two second sub-touch electrodes is not required, which is beneficial to reducing the thickness of the display panel 100.

Referring to fig. 4, the lap joint hole of the first metal layer 50 and the touch electrode layer 70 is located in the flat region between the retaining wall 90 and the partition region D, it can be understood that, in the retaining wall or the partition region, during the photolithography process for fabricating the lap joint hole, the thickness of the photoresist may have a non-uniform problem, which results in that the via hole cannot be completely exposed and formed. And the arrangement of the lap joint holes in the flat areas is beneficial to the realization of the lap joint holes.
Optionally, as shown in fig. 6, the first metal layer 50 further includes a second metal encapsulation portion 502 electrically insulated from the first metal encapsulation portion 501, and optionally, an orthographic projection of the second metal encapsulation portion 502 on the substrate 10 is located in the partition region D.

In the embodiment of the present invention, the first touch electrode 710 and the second touch electrode 720 are electrically connected through the first metal encapsulation portion 501 and the second metal encapsulation portion 502, so that an additional winding design is not required for connecting the two first sub-touch electrodes on the two sides of the accommodating hole 1 and the two second sub-touch electrodes on the two sides of the accommodating hole 1, which is beneficial to simplifying the touch electrode design in the display panel, and on the other hand, the second metal encapsulation portion 502 also has a certain encapsulation effect on the partition area, which is beneficial to improving the encapsulation reliability of the display panel. It is understood that, in other embodiments, one pair of the two second sub-touch electrodes and the two first sub-touch electrodes may be electrically connected through the corresponding first metal encapsulation portion or the second metal encapsulation portion, and the other pair may be electrically connected through the routing.
In some optional embodiments, the first touch electrode 710 and the second touch electrode 720 are disposed in different layers, and the accommodating hole is located at the intersection of the first touch electrode 710 and the second touch electrode 720.

Similarly, in the touch electrode layer 70: the second touch electrode 720 includes a plurality of electrode blocks, two adjacent electrode blocks need to be electrically connected to each other, when the first touch electrode and the second touch electrode are on the same layer, in order to reduce the number of layers in the display panel 100 and thus reduce the thickness of the display panel 100, in a specific implementation manner, two adjacent electrode blocks in the second touch electrode 720 may be connected by the first metal layer 50, specifically, the first metal layer 50 includes a second touch electrode bridging metal portion, and in the second touch electrode 720, except for the two second sub-touch electrodes, two adjacent electrode blocks are connected by the second touch electrode bridging metal portion.
