It is to be noted that, unless otherwise specified, technical or scientific terms used herein shall have the ordinary meaning as understood by those skilled in the art to which this application belongs.
A first aspect of an embodiment of the present application provides a display panel, as shown in fig. 1 to 8, including: the display panel comprises a plurality of sub display areas arranged in an array manner and a non-display area arranged between every two adjacent sub display areas, wherein the display panel comprises a reflecting layer, the reflecting layer is arranged in the non-display area, and the reflecting layer is used for enabling light irradiated to the reflecting layer to be subjected to mirror reflection.
The display panel provided by the application can be an OLED display panel, the mirror display device is mainly applied to scenes such as markets, vehicle-mounted rearview mirrors and the like, the PPI (pixel density) of the display device is low, and therefore the metal wiring has a large space and is located in the non-display area 2, and therefore the area of the non-display area 2 is large. As shown in fig. 3, the sub-display regions 1 correspond to sub-pixels of the display device, and the sub-pixel regions can emit light, while the non-display region 2 between two adjacent sub-display regions 1 does not emit light. In this embodiment, the reflective layer 3 is disposed in the non-display region 2, and the reflective layer 3 can cause the light to generate specular reflection. In the prior art, the transflective film needs to be attached to the display device, so that the mirror display of the display device can be realized, but the transflective film can completely cover the sub-display area 1, so that the light transmittance of the display area can be reduced, and the display brightness can be reduced. Meanwhile, the reflective layer 3 disposed in the non-display area 2 can be equivalent to a whole reflective layer 3, thereby realizing the mirror reflection of the display panel.
Specifically, as shown in fig. 1, fig. 2, fig. 5 and fig. 6, the display panel includes a back plate 4, a photoresist layer 5 and a first encapsulation layer 6, which are sequentially stacked, where the back plate 4 includes an array substrate 41, a metal routing layer 42, a first buffer layer 43, an anode layer 44, an electroluminescent device light-emitting layer 45, a cathode layer 46 and a second encapsulation layer 47, which are sequentially stacked; the cathode layer 46 includes a plurality of cathode regions 461 arranged in an array, a reflective opening is formed between two adjacent cathode regions 461, the reflective opening is arranged in the non-display region 2, and at least a portion of the reflective layer 3 faces the reflective opening.
The display panel comprises a back plate 4 and a color film which are sequentially stacked, a light resistance layer 5 comprises light resistances of three colors of red, green and blue, the light resistance layer 5 is arranged on the back plate 4 through a COE (chip on film) process and is positioned in a sub-display area 1, a first packaging layer 6 covers one side of the light resistance layer 5, which deviates from the back plate 4, the light resistance layer 5 can be protected, the first packaging layer 6 covers the sub-display area 1 and a non-display area 2, the light resistance layer 5 is directly formed on the back plate 4, the problem of reflectivity reduction caused by attaching the POL (polar alcohol) can be avoided, the brightness and the color gamut of the display panel can be improved, the manufacturing process of the display panel is simplified, and the yield of. Wherein, the reflector layer 3 in the backplate 4 is located non-display area 2, and light can shine on reflector layer 3 through the part that first encapsulated layer 6 corresponds to non-display area 2, and reflector layer 3 can make light take place specular reflection. Wherein, a portion of the metal routing layer 42 may be connected to the source/drain layer 418 in the array substrate 41 through a via. And the cathode layer 46 includes a plurality of cathode regions 461, each cathode region 461 may correspond to a plurality of sub-pixels or a sub-pixel of the display device, and a light reflecting opening is formed between two adjacent cathode regions 461, and the light reflecting opening is located in the non-display region 2. The metal routing layer 42 and the anode layer 44 are made of metal material, so that the light can be specularly reflected. However, although the cathode layer 46 is made of a metal material, when light is irradiated on the cathode region 461, the light is partially reflected and partially passes through the cathode region 461, and the cathode layer 46 cannot cause the light to be specularly reflected. In the prior art, since the cathode layer 46 covers the sub-display area 1 and the non-display area 2 completely, even if the anode layer 44 and the metal wiring layer 42 can make the light generate the mirror reflection, the light intensity is not enough because only part of the light can irradiate on the anode layer 44 and the metal wiring layer 42, and the display panel still cannot realize the mirror reflection effect, and the mirror reflection of the display device can only be realized by attaching the semi-transparent and semi-reflective film. In the present application, the anode layer 44 in the non-display area 2 and the metal wiring layer 42 in the non-display area 2 can be used as the reflective layer 3 to implement the mirror reflection of the display panel. Specifically, a part of the anode layer 44 may be located in the non-display area 2, a part of the metal wiring layer 42 may be located in the non-display area 2, and light may irradiate the anode layer 44 located in the non-display area 2 and/or the metal wiring layer 42 located in the non-display area 2 through the light reflecting openings. In addition, in the prior art, since the cathode layer 46 covers the sub-display region 1 and the non-display region 2 in a whole, and the non-display region 2 and the sub-display region 1 both have power consumption when the VSS signal is transmitted to the cathode layer 46, wherein the non-display region 2 is not used for displaying, in the prior art, the part of the cathode layer 46 corresponding to the non-display region 2 generates unnecessary power consumption not used for displaying of the display panel, whereas in the present embodiment, the cathode layer 46 is patterned, a plurality of cathode regions 461 are formed in the cathode layer 46, the cathode regions 461 do not cover the whole of the non-display region 2, and compared with the prior art, the power consumption corresponding to the non-display region 2 is not required to be generated, so as to effectively reduce the power consumption, and meanwhile, since the coverage area of the cathode layer 46 in the prior art is large, the longer the transmission route of the VSS signal is, the larger the voltage difference between the VSS signal transmission start terminal and the VSS signal, that is, the larger the voltage drop, the more uneven the voltage difference of the cathode layer 46, the more obvious the display Mura phenomenon caused by the uneven driving, but in the embodiment, the cathode coverage area is smaller, so the voltage difference between the starting end and the tail end is reduced during the VSS signal transmission process, thereby reducing the voltage drop, and simultaneously, the more even the voltage difference of each area is, thereby solving the display Mura problem caused by the uneven driving. In addition, in the embodiment, since the light can enter the back plate 4 through the photoresist layer 5, a Black Matrix (BM) does not need to be disposed in the display panel provided in the embodiment, which not only saves BM materials, but also ensures that the light enters the back plate 4.

Specifically, as shown in fig. 1, fig. 2, and fig. 4 to fig. 7, the light-reflecting layer 3 further includes a second light-reflecting layer 32, the second light-reflecting layer 32 is disposed on the same layer as the anode layer 44, and the first light-reflecting layer 31 is disposed in the non-display region 2; the orthographic projection of the first light reflecting layer 31 on the array substrate 41 is not overlapped or partially overlapped with the orthographic projection of the second light reflecting layer 32 on the array substrate 41.
The second light reflecting layer 32 in the light reflecting layer 3 is disposed on the same layer as the anode layer 44, and is made of the same material as the anode layer 44, so that light can be specularly reflected, and the second light reflecting layer 32 and the anode layer 44 can be formed at the same time, so that a mask plate can be used when the second light reflecting layer 32 and the anode layer 44 are formed. The first light reflecting layer 31 and the second light reflecting layer 32 are at most partially overlapped, i.e. they are not overlapped or partially overlapped, so that the coverage area of the light reflecting layer 3 can be increased by arranging the second light reflecting layer 32. The anode layer 44 includes a plurality of sub-pixel anodes 441, the sub-pixel anodes 441 are disposed in the sub-display region 1, and the array is disposed on the display panel.

The first reflective layer 31 partially or completely faces the gap between the second reflective layer 32 and the adjacent column of sub-pixel anodes 441, so that light passing through the gap between the second reflective layer 32 and the adjacent column of sub-pixel anodes 441 can irradiate the first reflective layer 31 to generate specular reflection, thereby increasing the coverage area of the reflective layer 3 and improving the specular reflection effect of the display panel. The first light reflecting layer 31 and the second light reflecting layer 32 extend in a first direction in the plane, that is, the first light reflecting layer 31 and the second light reflecting layer 32 are in the shape of stripes. Preferably, the first and second light reflecting layers 31 and 32 are capable of completely covering the first stripe-shaped areas extending in the first direction in the non-display area 2.

In this case, the first light emitting layer and the second light emitting layer can serve as the reflective layer 3 to cause mirror reflection of the display device, and can also serve as the cathode trace to transmit the VSS signal to the cathode region 461. When the first reflective layer 31 and the second reflective layer 32 transmit the VSS signal together, a double-layer wiring is implemented, so that the resistance is reduced, and thus, the voltage drop in the VSS signal transmission process can be reduced. The second light reflecting layer 32 is formed with a cathode connection hole, and the cathode layer 46 is connected to the first light reflecting layer 31 through the cathode connection hole.
