Detailed Description
Exemplary embodiments of the present disclosure will be described in more detail below with reference to the accompanying drawings. While exemplary embodiments of the present disclosure are shown in the drawings, it should be understood that the present disclosure may be embodied in various forms and should not be limited to the embodiments set forth herein. Rather, these embodiments are provided so that this disclosure will be thorough and complete, and will fully convey the scope of the disclosure to those skilled in the art.
It is noted that unless otherwise indicated, technical or scientific terms used herein should be given the ordinary meaning as understood by one of ordinary skill 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 light reflecting layer, wherein the light reflecting layer is arranged in the non-display area and is used for enabling light irradiated to the light reflecting layer to be subjected to specular reflection.
The display panel provided by the application can be an OLED display panel, and the mirror display device is mainly applied to scenes such as markets and vehicle-mounted rearview mirrors, and the PPI (pixel density) of the display device is low, so that the metal wiring has a larger space, and the metal wiring is positioned in the non-display area 2, so that the area of the non-display area 2 is larger. As shown in fig. 3, the sub-display area 1 corresponds to a sub-pixel of the display device, and the sub-pixel area may emit light, while the non-display area 2 between two adjacent sub-display areas 1 does not emit light. In this embodiment, the reflective layer 3 is disposed in the non-display area 2, and the reflective layer 3 can make light specularly reflected. In the prior art, the semi-transparent and semi-reflective film is attached to the display device to realize mirror surface display of the display device, but the semi-transparent and semi-reflective film can fully cover the sub-display area 1, so that the light transmittance of the display area is reduced, and the display brightness is reduced. Meanwhile, the reflective layer 3 arranged in the non-display area 2 can be equivalent to an entire reflective layer 3, so that the specular reflection of the display panel is realized.
Specifically, as shown in fig. 1, 2, 5 and 6, the display panel includes a back plate 4, a photoresist layer 5 and a first encapsulation layer 6, which are sequentially stacked, and the back plate 4 includes an array substrate 41, a metal wiring 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, and a reflective opening is formed between two adjacent cathode regions 461, the reflective opening is disposed in the non-display area 2, and the reflective layer 3 at least partially faces the reflective opening.
Wherein, display panel is including backplate 4 and the various membrane that stacks gradually the setting, light resistance layer 5 includes red, green, blue three kinds of light resistance, light resistance layer 5 passes through COE technology and sets up on backplate 4, and be located sub-display area 1, first encapsulation layer 6 covers in light resistance layer 5 one side that deviates from backplate 4, can protect light resistance layer 5, first encapsulation layer 6 covers in sub-display area 1 and non-display area 2, wherein, directly form light resistance layer 5 on backplate 4, not only can avoid pasting the problem that the reflectivity that POL brought reduces, can also improve display panel's luminance and colour gamut, simplify display panel's manufacturing process simultaneously, improve the yields of product. The reflective layer 3 in the back plate 4 is located in the non-display area 2, and light can be irradiated on the reflective layer 3 through a portion of the first encapsulation layer 6 corresponding to the non-display area 2, and the reflective layer 3 can enable the light to be specularly reflected. Wherein, a portion of the metal wiring 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 one 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 wiring layer 42 and the anode layer 44 are made of metal materials, so that light can be reflected in a specular manner. Although the cathode layer 46 is made of metal, when light irradiates the cathode region 461, a part of the light is reflected, and a part of the light passes through the cathode region 461, so that the cathode layer 46 cannot make the light specularly reflect. In the prior art, since the cathode layer 46 covers the sub-display area 1 and the non-display area 2 entirely, even if the anode layer 44 and the metal wiring layer 42 can make light rays specularly reflected, only part of the light rays can irradiate on the anode layer 44 and the metal wiring layer 42, the light rays are not strong enough, the display panel still cannot achieve the effect of specularly reflecting, and the specularly reflecting of the display device can only be achieved 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 realize the specular reflection of the display panel. Specifically, a portion of the anode layer 44 may be located in the non-display area 2, and a portion of the metal trace layer 42 may be located in the non-display area 2, so that light may be irradiated to the anode layer 44 located in the non-display area 2 and/or to the metal trace layer 42 located in the non-display area 2 through the reflective opening. In addition, in the prior art, since the cathode layer 46 covers the sub-display area 1 and the non-display area 2 entirely, when VSS signals are transmitted to the cathode layer 46, the non-display area 2 and the sub-display area 1 have power consumption, and therefore, in the prior art, the portion of the cathode layer 46 corresponding to the non-display area 2 will generate unnecessary power consumption that is not used for display of the display panel, whereas in the present embodiment, the cathode layer 46 is patterned, and a plurality of cathode areas 461 are formed in the cathode layer 46, the cathode areas 461 no longer cover the entire non-display area 2, compared with the prior art, the power consumption corresponding to the non-display area 2 is not required to be generated, so that the power consumption is effectively reduced, and meanwhile, because the coverage area of the cathode layer 46 is larger in the prior art, the longer the transmission route of VSS signals causes the difference between the starting end of VSS signal transmission and the end of VSS signal transmission to be larger, that is the more uneven in the voltage difference of the cathode layer 46, so that the uneven in driving causes display Mura phenomenon to be obvious, and the more in the embodiment, the coverage area is smaller, and the voltage difference between the starting end of VSS signal transmission is reduced, and the average voltage difference is reduced. In addition, in the present embodiment, since light will enter the back plate 4 through the photoresist layer 5, a Black Matrix (BM) is not required to be disposed in the display panel provided in the present embodiment, which not only saves BM materials, but also ensures that light enters the back plate 4.
Specifically, as shown in fig. 1, 2 and 4 to 7, the light reflecting layer 3 includes a first light reflecting layer 31, the first light reflecting layer 31 and the metal routing layer 42 are disposed on the same layer, and the first light reflecting layer 31 is disposed in the non-display area 2.
As shown in fig. 4, the direction indicated by the arrow a is a first direction, the direction indicated by the arrow B is a second direction, the first reflective layer 31 may extend along the first direction along the plane where the first reflective layer 31 is located, and the material of the first reflective layer 31 may be the same as that of the metal routing layer 42, and may enable the light to be specularly reflected, so that the first reflective layer 31 may be formed simultaneously with the metal routing layer 42, and a mask may be used when forming the first reflective layer 31 and the metal routing layer 42.
Specifically, as shown in fig. 1, 2 and 4 to 7, the light reflecting layer 3 further includes a second light reflecting layer 32, the second light reflecting layer 32 is disposed in the same layer as the anode layer 44, and the first light reflecting layer 31 is disposed in the non-display area 2; the front projection of the first reflective layer 31 on the array substrate 41 is not coincident with or partially coincident with the front projection of the second reflective layer 32 on the array substrate 41.
The second light reflecting layer 32 and the anode layer 44 in the light reflecting layer 3 are arranged in the same layer, and are 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 simultaneously formed, 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., not overlapped or partially overlapped, and therefore, by providing the second light reflecting layer 32, the coverage area of the light reflecting layer 3 can be increased. The anode layer 44 includes a plurality of sub-pixel anodes 441, the sub-pixel anodes 441 are disposed in the sub-display area 1, and the array is disposed in the display panel. The first reflective layer 31 may not be connected to the sub-pixel anode 441, the second reflective layer 32 may extend along the first direction in the plane of the anode layer 44, and gaps are formed between the second reflective layer 32 and the plurality of sub-pixel anodes 441 in adjacent columns, where each column of sub-pixel anodes 441 is disposed along the first direction. The first reflective layer 31 is partially or completely opposite to the gaps between the second reflective layer 32 and the adjacent row of sub-pixel anodes 441, so that the light passing between the second reflective layer 32 and the adjacent row of sub-pixel anodes 441 can be irradiated on the first reflective layer 31 to be specularly reflected, thereby improving the coverage area of the reflective layer 3 and the specular reflection effect of the display panel. The first light reflecting layer 31 and the second light reflecting layer 32 extend along a first direction in a plane where the first light reflecting layer 31 and the second light reflecting layer 32 are located, that is, the first light reflecting layer 31 and the second light reflecting layer 32 are in a strip shape. Among them, it is preferable that the first light reflecting layer 31 and the second light reflecting layer 32 can entirely cover the first stripe-shaped region extending in the first direction within the non-display area 2.
Specifically, the cathode region 461 is connected to the first light reflecting layer 31 through a via, and the first light reflecting layer 31 is used for transmitting a negative cathode pressure signal.

Alternatively, as shown in fig. 1, 2 and 7, since the second reflective layer 32 is located between the first reflective layer 31 and the cathode layer 46, the sub-pixel cathode via hole can be connected to the second reflective layer 32, and the second reflective layer 32 is connected to the first reflective layer 31 again via hole, in this embodiment, since the material of the second reflective layer 32 is the same as that of the anode layer 44, and since the anode layer 44 is not suitable for long-distance routing, the second reflective layer 32 needs to be connected to the first reflective layer 31 via hole. At this time, the first light emitting layer and the second light emitting layer may not only serve as the light reflecting layer 3 to cause the display device to be specularly reflected, but also serve as a cathode wiring 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 through which the cathode layer 46 is connected to the first light reflecting layer 31.
Specifically, as shown in fig. 5, the cathode region 461 has a bar shape and extends in the first direction in the cathode layer 46, and the cathode region 461 covers a plurality of sub-display areas 1 arranged in the first direction; the light reflecting layer 3 extends along the first direction on the plane of the light reflecting layer; the orthographic projection of the cathode region 461 on the array substrate 41 is alternately arranged with the orthographic projection of the light reflecting layer 3 on the array substrate 41.

The non-display area 2 of the display panel includes a first stripe-shaped area extending along a first direction and a second stripe-shaped area extending along a second direction, wherein the first direction is a column direction of the sub-display area 1, and therefore, the first stripe-shaped area is the non-display area 2 between two adjacent columns of the sub-display areas 1, and in this embodiment, the reflective layer 3 covers the first stripe-shaped area to achieve a specular reflection effect of the display panel.
