Referring to fig. 1, some embodiments of the utility model provide a mirror display panel 100, in which the mirror display panel 100 has a plurality of light emitting regions 101 and a non-light emitting region 102 separating the light emitting regions 101.

The plurality of light emitting areas 101 may include a plurality of red light emitting areas, a plurality of green light emitting areas, and a plurality of blue light emitting areas. The mirror display panel 100 can realize a display function by driving the light emitting devices in the plurality of light emitting regions 101 to emit light. The present invention does not limit the number of the light emitting regions 101, the arrangement of the light emitting regions 101 of different colors, and the size of the light emitting regions 101, as long as the mirror display panel 100 can display images.

In some embodiments, with reference to fig. 1, the mirror display panel 100 includes a substrate 10, a plurality of light emitting devices 20, a light shielding structure 30, at least one barrier layer 40, and a mirror reflection layer 50.

It is noted that the type of substrate 10 includes a variety of types, including, for example, but not limited to, the following examples.

In some examples, substrate 10 may be a rigid substrate. The rigid substrate may be, for example, a glass substrate or a PMMA (Polymethyl methacrylate) substrate.

In other examples, substrate 10 may be a flexible substrate. The flexible substrate may be, for example, a PET (Polyethylene terephthalate) substrate, a PI (Polyimide) substrate, or a PEN (Polyethylene naphthalate) substrate.

With continued reference to fig. 1, a plurality of light emitting devices 20 are disposed on one side of the substrate 10, and one light emitting device 20 is located in one light emitting region 101. On the basis, referring to fig. 2 and fig. 3, the mirror display panel 100 further includes a pixel driving circuit 11, and the pixel driving circuit 11 may be located on a side of the light emitting device 20 close to the substrate 10 and electrically connected to the light emitting device 20. The pixel driving circuit is coupled to one gate scanning signal line and one data signal line. The pixel driving circuit transmits the data signal transmitted from the data signal line to the light emitting device under the control of the gate scan signal transmitted from the gate scan signal line, thereby driving the light emitting device 20 to emit light.

For example, referring to fig. 2 and 3, the structure of the pixel driving circuit 11 may include various structures, which are not limited in the present invention. For example, the structure of the pixel driving circuit 11 may be "6T 1C", "7T 1C", "6T 2C", or "7T 2C"; here, "T" indicates a thin film transistor, the number preceding "T" indicates the number of thin film transistors, "C" indicates a storage capacitor, and the number preceding "C" indicates the number of storage capacitors. For another example, the thin film transistor included in the pixel driving circuit 11 may be a thin film transistor of a bottom gate structure or a thin film transistor of a top gate structure. Only one thin film transistor 111 and one storage capacitor 112 are illustrated in the drawings of some embodiments of the present invention.

For example, with continued reference to fig. 2 and 3, the light emitting device 20 may include an anode (anode)201, a light emitting functional layer 202, and a cathode (cathode) 203. The anode 201 is electrically connected to the drain of the thin film transistor 111 serving as a driving transistor in the pixel driving circuit 11.

In some examples, the light emitting function layer 202 may include a light Emitting Layer (EL). In other examples, the light emitting function layer 202 includes one or more of an Electron Transport Layer (ETL), an Electron Injection Layer (EIL), a Hole Transport Layer (HTL), and a Hole Injection Layer (HIL) in addition to the light emitting layer. In the case where the mirror display panel 100 is an organic electroluminescence display panel, the light emitting layer is an organic light emitting layer. In the case where the mirror display panel 100 is a quantum dot electroluminescent display panel, the light-emitting layer is a quantum dot light-emitting layer.

With reference to fig. 1, the light shielding structure 30 is disposed on one side of the substrate 10, and the light shielding structure 30 is located in the non-light emitting region 102.

The light blocking structure 30 may be composed of a black material or other color light absorbing material so that the light blocking structure 30 may absorb most of the light irradiated thereto.

And at least one barrier layer 40 disposed on a side of the plurality of light emitting devices 20 and the light shielding structure 30 away from the substrate 10 as a whole. The structure of at least one barrier layer 40 includes a plurality of kinds, and can be selected according to actual conditions. For example, the barrier layer 40 may be formed as a single layer, a double layer, or multiple layers.

The specular reflection layer 50 is disposed on a side of the barrier layer 40 away from the substrate 10, and the specular reflection layer 50 is located in the non-light emitting region 102. I.e. the process is repeated. The specular reflection layer 50 has a plurality of openings, one opening corresponding to one light emitting region 101.

Illustratively, the specular reflection layer 50 may be a metal reflection layer 51, and the metal reflection layer 51 is located in the non-light emitting region 102. With this arrangement, not only can the light incident on the mirror display panel 100 be effectively reflected by the metal reflective layer 51, but also the situation that the mirror display panel 100 cannot normally display because the light emitted by the light emitting region 101 is blocked by the mirror reflective layer 50 can be avoided.

The specular reflection layer 50 may be a single metal reflection layer, and for example, the material of the specular reflection layer 50 may include at least one of aluminum, molybdenum, titanium, silver, and copper.

Alternatively, the specular reflection layer 50 may also be a structure including a plurality of metal reflection layers. Illustratively, the specular reflection layer 50 may include a titanium metal layer, an aluminum metal layer, and a titanium metal layer, which are sequentially stacked. Alternatively, the specular reflection layer 50 may include an indium tin oxide layer, a silver metal layer, and an indium tin oxide layer, which are sequentially stacked.

It should be noted that, the specular reflection layer 50 is located in the non-light emitting region 102, and therefore, in the process of fabricating the specular reflection layer 50 on the blocking layer 40, a whole reflection layer (for example, a metal thin film layer) needs to be fabricated on the blocking layer 40, then a layer of photoresist is fabricated on the metal thin film, and through exposure and development, a portion of the photoresist corresponding to a portion of the metal thin film that needs to be removed by etching (i.e., a portion of the metal thin film corresponding to the light emitting region 101) can be removed, however, in the prior art, by directly forming the specular reflection layer 50 on the surface of the light shielding structure 30 away from the substrate 10, the step difference between two ends of the light shielding structure 30 is large, so that not only the aperture ratio of the specular reflection layer 50 is limited by the aperture ratio of the light shielding structure 30, but also the fabrication process of the specular reflection layer 50 is complex, which easily causes that the portion of the metal thin film that needs to be removed by etching may have photoresist exposure, When the development is insufficient, metal remains are generated, and the mirror display effect of the mirror display panel 100 is reduced.

In the mirror display panel provided by some embodiments of the present invention, on one hand, by arranging at least one barrier layer 40 on one side of the light shielding structure away from the substrate, the surface of the barrier layer 40 away from the substrate 10 is relatively flat, and fabricating the mirror reflection layer 50 on the surface of the barrier layer 40 away from the substrate 10, the process difficulty of fabricating the mirror reflection layer 50 is reduced, and the problem of insufficient etching of a metal film is not easily caused, so that metal residue is not easily generated, and the edge of the mirror reflection layer 50 is relatively flat, thereby improving the mirror display effect of the mirror display panel 100; on the other hand, after the barrier layer 40 is disposed between the light shielding structure 30 and the specular reflection layer 50, the aperture ratio of the specular reflection layer 50 is no longer limited by the aperture ratio of the light shielding structure 30, as long as the specular reflection layer 50 is located in the non-light emitting region 102, and the light transmission efficiency of the specular display panel 100 can be improved.

In some embodiments, referring to fig. 2 and fig. 3, the mirror display panel 100 further includes an encapsulation layer 21 disposed on a side of the light emitting device 20 away from the substrate 10.

The Encapsulation layer 21 may be a Thin Film Encapsulation (TFE), or may be an Encapsulation substrate. The encapsulation layer 21 is configured to encapsulate the pixel driving circuit 11 and the light emitting device 20 on the substrate 10 to block water and oxygen, so as to prevent water and oxygen from corroding the light emitting device 20, thereby affecting the light emitting efficiency and the service life of the light emitting device 22.

In some examples, with continuing reference to fig. 2 and 3, encapsulation layer 21 may include: the organic light emitting device includes a first inorganic barrier layer 211, an organic barrier layer 212 disposed on a side of the first inorganic barrier layer 211 away from the substrate 10, and a second inorganic barrier layer 213 disposed on a side of the organic barrier layer 212 away from the substrate 10. The first inorganic barrier layer 211 and/or the second inorganic barrier layer 213 may be formed, for example, by using an inorganic insulating material and using a deposition process; the organic barrier layer 212 may be formed using an organic insulating material and prepared using an inkjet printing process, for example.

In some embodiments, referring to fig. 2, the light shielding structure 30 is located on the surface of the encapsulation layer 21 away from the substrate 10. On this basis, the at least one barrier layer 40 is located between the light shielding structure 30 and the specular reflection layer 50, and the at least one barrier layer 40 may include a first organic insulating layer 41.

In this embodiment, on one hand, by arranging the first organic insulating layer 41 between the light shielding structure 30 and the specular reflection layer 50, the surface of the first organic insulating layer 41 is relatively flat, and the specular reflection layer 50 is manufactured on the surface of the first organic insulating layer 41 away from the substrate 10, which not only reduces the process difficulty, but also is not easy to cause the problem of insufficient etching of a metal film, so that metal residue is not easy to generate, and the edge of the specular reflection layer 50 is relatively flat, thereby improving the specular display effect of the specular display panel 100; on the other hand, after the first organic insulating layer 41 is disposed between the light shielding structure 30 and the specular reflection layer 50, the aperture ratio of the specular reflection layer 50 is not limited by the aperture ratio of the light shielding structure 30, as long as the specular reflection layer 50 is located in the non-light emitting region 102, and the light transmission efficiency of the specular display panel 100 can be improved.

In some embodiments, with reference to fig. 2, the thickness d1 of the first organic insulating layer 41 is less than or equal to 2.5 um. For example, the thickness d1 of the first organic insulating layer 41 may be 0.5um, 1um, 1.5um, 2um, 2.5um, etc.

In this example, through setting up first organic insulation layer 41, not only can reduce the technology degree of difficulty of the preparation of specular reflection layer 50, guarantee that the edge of specular reflection layer 50 is level and smooth relatively, improved mirror surface display effect of mirror surface display panel 100, thickness d1 less than or equal to 2.5um of first organic insulation layer 41 can prevent that mirror surface display panel 100 from taking place the cross color at the in-process that realizes the mirror surface display function in order to improve user experience.

In some embodiments, referring to FIG. 3, the mirror display panel 100 further comprises a pixel defining layer 31. The pixel defining layer 31 has a plurality of openings defined for receiving the plurality of light emitting devices 20. That is, one light emitting device 20 is located within one opening.

In some examples, with continued reference to fig. 3, the pixel definition layer 31 is multiplexed into the light blocking structure 30. At this time, the pixel defining layer 31 may be composed of a black material or a light absorbing material of other colors so that the pixel defining layer 31 may absorb most of the light irradiated thereto.

In this example, the pixel defining layer 31 is multiplexed into the light shielding structure 30, so that not only the mirror display can be realized, but also the manufacturing process of the mirror display panel 100 can be reduced, and the manufacturing cost can be saved.

Based on this, and by way of example, with continued reference to fig. 3, the encapsulation layer 21 is reused as the barrier layer 40 described above. In this case, the at least one barrier layer 40 includes a multi-layer structure composed of a first inorganic barrier layer 211, an organic barrier layer 212, and a second inorganic barrier layer 213.

In this embodiment, the manufacturing process of the mirror display panel 100 is reduced and the manufacturing cost is saved by reusing the encapsulation layer 21 as the barrier layer 40.

In some embodiments, with continued reference to FIG. 3, the distance d2 between the pixel defining layer 31 and the specular reflective layer 50 is between 10um and 14 um. For example, the distance d2 between the pixel defining layer 31 and the specular reflective layer 50 can be 10um, 11um, 12um, 13um, 14um, and so on.

In this embodiment, when the distance d2 between the pixel defining layer 31 and the specular reflection layer 50 is equal to or close to 14mm, color cross-talk of the specular display panel 100 during the process of implementing the specular display function can be prevented to a certain extent, and meanwhile, it is more favorable to prevent water and oxygen from corroding the light emitting device 20, thereby affecting the light emitting efficiency and the service life of the light emitting device 22. When the distance d2 between the pixel defining layer 31 and the specular reflection layer 50 is equal to or approximately equal to 10mm, color cross-talk of the specular display panel 100 during the implementation of the specular display function can be better prevented, and the light emitting device 20 can be prevented from being corroded by water and oxygen to a certain extent, thereby affecting the light emitting efficiency and the service life of the light emitting device 22.

In some embodiments, referring to fig. 1-3, an orthographic projection of the specular reflective layer 50 on the substrate 10 at least partially overlaps an orthographic projection of the light blocking structure 30 on the substrate 10.

In this example, in the case of providing at least one barrier layer 40, the aperture ratio of the specular reflection layer 50 is no longer limited by the aperture ratio of the light shielding structure 30. In some examples, an orthographic projection of the specular reflective layer 50 on the substrate 10 may completely cover an orthographic projection of the light blocking structure 30 on the substrate 10. In other examples, an orthographic projection of the specular reflective layer 50 on the substrate 10 may completely overlap with an orthographic projection of the light blocking structure 30 on the substrate 10. In still other examples, a portion of an orthographic projection of the specular reflective layer 50 on the substrate 10 overlaps a portion of an orthographic projection of the light blocking structure 30 on the substrate 10.

In some embodiments, with continued reference to fig. 1 to 3, the mirror display panel 100 further includes a second organic insulating layer 60 disposed on a side of the mirror reflective layer away from the substrate 10. The second organic insulating layer 60 may protect the mirror reflective layer 50.

In summary, in the mirror display panel 100 provided in some embodiments of the present invention, on one hand, by providing at least one barrier layer 40, the surface of the barrier layer 40 away from the substrate 10 is relatively flat, and fabricating the mirror reflection layer 50 on the surface of the barrier layer 40 away from the substrate 10, the process difficulty of fabricating the mirror reflection layer 50 is reduced, and the problem of insufficient etching of the metal film is not easily caused, so that metal residue is not easily generated, and the edge of the mirror reflection layer 50 is relatively flat, thereby improving the mirror display effect of the mirror display panel 100; on the other hand, after the barrier layer 40 is disposed between the light shielding structure 30 and the specular reflection layer 50, the aperture ratio of the specular reflection layer 50 is no longer limited by the aperture ratio of the light shielding structure 30, as long as the specular reflection layer 50 is located in the non-light emitting region 102, and the light transmission efficiency of the specular display panel 100 can be improved.
