All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.

It should be appreciated that reference throughout this specification to "one embodiment" or "an embodiment" means that a particular feature, structure or characteristic described in connection with the embodiment is included in at least one embodiment of the present invention. Thus, the appearances of the phrases "in one embodiment" or "in an embodiment" in various places throughout this specification are not necessarily all referring to the same embodiment. Furthermore, the particular features, structures, or characteristics may be combined in any suitable manner in one or more embodiments.

In various embodiments of the present invention, it should be understood that the sequence numbers of the following processes do not mean the execution sequence, and the execution sequence of each process should be determined by its function and inherent logic, and should not constitute any limitation to the implementation process of the embodiments of the present invention.

Fig. 1 is a schematic structural diagram of a vertical cross section of a polar panel 100 according to an embodiment of the present invention, referring to fig. 1, the polar panel 100 includes a cover plate 101, an optically transparent adhesive 102, a polarizing layer 103, a first glass layer 104, a gap layer 105, and a second glass layer 106, which are sequentially disposed, where the polarizing layer 103 includes a polarizer 1031 and an optically transparent resin 1032;

wherein the first surface 1041 of the first glass layer 104, the second surface 1061 of the second glass layer 106, and the third surface 1062 of the second glass layer 106 are coated with an anti-reflective film having a coverage area including a pole hole area of the pole screen, the first surface 1041 being opposite to the second surface 1061. The pole hole area can be a certain preset area in the pole screen, wherein incident light can penetrate through the pole screen to reach the camera under the screen.

In the embodiment of the present invention, taking an AMOLED (Active-matrix organic light-emitting diode) pole panel as an example, as shown in fig. 1, in the pole panel 100, a cover plate 101, an optically transparent adhesive 102, a polarizing layer 103, a first glass layer 104, a gap layer 105, and a second glass layer 106 are sequentially disposed to form the pole panel, where the polarizing layer 103 includes a polarizer 1031 and an optically transparent resin 1032. Wherein the discontinuous structure of the gap layer 105 is spaced from the first glass layer 104 and the second glass layer 105 to form a vacuum region, thereby forming a glass-vacuum-glass laminate. Since the refractive index of the vacuum medium is 1 and the refractive index of the glass medium is 1.5 during the light transmission process, the difference is large, when the camera is placed under the pole screen in the prior art, the incident light enters from the cover plate 101 and passes through the optical transparent adhesive 102, the polarization layer 103, the first glass layer 104, the gap layer 105, and the second glass layer 106, due to the laminated form of glass-vacuum-glass of the first glass layer 104, the gap layer 105, and the second glass layer 106, the incident light is reflected, the optical path interference is generated, and finally the phenomenon of a mottled aperture appears during the photographing process.

In the embodiment of the present invention, the direction of the incident light entering the pole screen, that is, the direction from the cover plate 101, the optically transparent adhesive 102, the polarization layer 103, the first glass layer 104, the gap layer 105, and the second glass layer 106 is regarded as from top to bottom, and the antireflection films are plated on the first surface 1041 of the first glass layer 104, the first surface 1061 of the second glass layer 106, and the second surface 1062 of the second glass layer 106, so as to avoid the reflection phenomenon of the incident light when the incident light enters media with different refractive indexes, and eliminate the problem of the camera under the pole screen that a mottled aperture occurs during the shooting process. Optionally, for the purpose of saving the manufacturing cost and reducing the thickness of the pole screen, an anti-reflection film may be plated on at least one of the first surface 1041 of the first glass layer 104, the second surface 1061 of the second glass layer 106, and the third surface 1062 of the second glass layer 106 to partially eliminate the reflection phenomenon and reduce the occurrence of the mottled aperture problem. In addition, the pole hole region may be a region where incident light can pass through the pole screen to the under-screen camera, and in the polarizing layer 103 as shown in fig. 1, the incident light can pass through the optically transparent resin 1032 and cannot pass through the polarizer 1031 to the under-screen camera. Accordingly, the pole aperture region of the polarizing layer 103 includes the region covered with the optically transparent resin 1032 except for the polarizing plate 1031. In the first glass layer 104, the gap layer 105 and the second glass layer 106 below the polarizing layer 103, the pole hole area of each layered layer can be larger than or equal to the pole hole area of the polarizing layer, so that the antireflection film covering the area including the pole hole area can better eliminate the reflection phenomenon and avoid the generation of the mottled aperture.

Optionally, the anti-reflection film comprises a first film layer and a second film layer which are alternately superposed; the refractive index of the first film layer is lower than the refractive index of the second film layer.

In the embodiment of the invention, the action mechanism of the anti-reflection film is that the film layers with different refractive indexes are alternately superposed, so that the reflected light is mutually counteracted, and the phase of the transmitted light is mutually enhanced, therefore, in the coating process of the anti-reflection film, only the first film layer plated firstly needs to be kept to be alternately superposed with the second film layer, and the refractive index of the first film layer plated firstly is lower than that of the second film layer plated later, and the specific material can be selected by the process conditions and the process cost.

Optionally, the number of the first film layers and the number of the second film layers which are alternately stacked is greater than or equal to 5.

In the embodiment of the present invention, in order to ensure the antireflection effect of the antireflection film, optionally, the number of the alternately stacked first film layers and second film layers is greater than or equal to 5, so as to enhance the antireflection effect of the antireflection film by increasing the number of the alternately stacked first film layers and second film layers in the antireflection film, in general, the greater the number of the alternately stacked first film layers and second film layers, the thicker the antireflection film is, but the thickness of the antireflection film is also related to the thickness of the first film layers and the second film layers themselves. Therefore, in order to avoid the problem that the thickness of the anti-reflection film is too thick, which causes the increase of the thickness of the pole screen, the number of layers of the first film layer and the second film layer can be controlled.

Optionally, the first membrane layer comprises a silicon dioxide layer.

Optionally, the second film layer includes any one of a titanium dioxide layer, a niobium pentoxide layer, a lanthanum titanate layer, and a silicon nitride layer.

Taking the titanium dioxide layer and the silicon dioxide layer as an example, the embodiment of the present invention does not limit the material of the specific coating film.

Optionally, the thickness of the anti-reflection film is 100-500 nm.
