Detailed Description
In order to make the objects, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are some, but not all, embodiments of the present invention. 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.
The terminology used in the embodiments of the invention is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention. As used in the examples of the present invention and the appended claims, the singular forms "a," "an," and "the" are intended to include the plural forms as well, unless the context clearly indicates otherwise.
As shown in fig. 1, fig. 2 and fig. 3, fig. 1 is a schematic structural diagram of a display panel in an embodiment of the present invention, fig. 2 is a schematic partial enlarged view of a region a in fig. 1, and fig. 3 is a schematic structural diagram of a cross section in a direction BB' in fig. 2, and an embodiment of the present invention provides a display panel, including: a light-transmitting region 1, a light-transmitting edge region 11 surrounding the light-transmitting region 1, a display region 2 surrounding the light-transmitting edge region 11; a display film layer 3, the display film layer 3 including a light emitting device 30 in a display area; the reflective layer 4, the reflective layer 4 sets up in the light-emitting side of showing rete 3, and is located between display area 2 and the printing opacity region 1, is located printing opacity border region 11 promptly, and in printing opacity border region 11, from printing opacity region 1 to display area 2's orientation, from B ' to B ' in fig. 2 promptly, the surface that the reflective layer 4 is close to one side of showing rete 3 is the undulation structure.
Specifically, the light-transmitting area 1 is a light-transmitting portion of the display panel, and in the display device having the display panel, a light-sensing unit is disposed inside the light-transmitting area 1 of the display panel or at a position corresponding to the light-transmitting area 1 on the non-light-emitting side of the display panel, and is configured to obtain light from the light-emitting side of the display panel through the light-transmitting area 1, so as to implement corresponding functions, such as a fingerprint unlocking unit, a light control switch, a front camera, and the like. In addition, the light transmission region 1 may be a region where a physical through hole is located on the display panel to realize light transmission, or the light transmission region 1 may also be a region where a transparent film structure is located on the display panel, that is, the light transmission region 1 does not need to dig a physical through hole, but realizes light transmission in the region with the transparent film, when the display panel is applied to a display device, for example, applied to a mobile phone, the back of the display panel is provided with, for example, a front camera at a position corresponding to the light transmission region 1, and the front camera realizes a front shooting function through the light transmission region 1, including shooting and shooting video. It should be noted that, in the embodiment of the present invention, for example, as shown in fig. 1, the light-transmitting area 1 may be located in the middle of the display area 2 and is completely surrounded by the display area 2, but in other realizable embodiments, the light-transmitting area may also be located at the edge of the display area, that is, the light-transmitting edge area surrounds the light-transmitting area halfway, and the display area surrounds the light-transmitting edge area halfway and the light-transmitting area halfway. As shown in fig. 3, the light emitting device 30 is disposed in the display region 2, and light emitted from the light emitting device 30 at the edge of the display region 2 near the light transmitting region 1 is emitted toward all sides of the light emitting side.
In the prior art, no reflective layer is provided, and other components are provided at the periphery of the light-emitting side light-transmitting region of the display film layer, and these components reflect light emitted from the light-emitting device, so that a large amount of light is directly reflected into the light-transmitting region.
In the embodiment of the present invention, since the light-emitting side of the display film 3 is provided with the reflective layer 4, and the reflective layer 4 is located between the display region 2 and the light-transmitting region 1, when light is emitted toward the light-transmitting region 1, the light is emitted to a surface of the reflective layer 4 close to the display film 3, and the surface of the reflective layer 4 close to the display film 3 is in a relief structure, so that the relief structure has a surface facing a side other than the light-transmitting region 1, when the light is irradiated onto the surface, the direction of the reflected light is changed, so that more reflected light is emitted in a direction deviating from the light-transmitting region 1 (the arrow in fig. 3 is in the light direction), thereby reducing the light reflected to the light-transmitting region 1, and improving adverse effects caused by the pixel light being emitted to the photosensitive unit of the light-transmitting region.
Alternatively, as shown in fig. 2, the light reflecting layer 4 is disposed around the light transmitting region 1 to reflect light from the light emitting device 30 in the display region 2 to the outside of the light transmitting region 1 as much as possible.
Alternatively, the material of the light-reflecting layer 4 comprises a metal, which has good reflective properties and is relatively easy to fabricate to form the surface of the relief structure.
Alternatively, as shown in fig. 3, the cross section of the light reflecting layer 4 is zigzag in a direction perpendicular to the plane of the display panel and extends from the light transmitting region 1 to the display region 2.
Specifically, in the zigzag structure, the light reflecting layer 4 necessarily has a surface facing a side away from the light transmitting region 1, and when light from the light emitting device 30 in the display region 2 is irradiated to the surface, more light is reflected to the outside of the light transmitting region 1, and in the zigzag structure, on one hand, the space occupied by the light reflecting layer 4 in a direction perpendicular to the plane of the display panel is small, and on the other hand, the zigzag structure has more surfaces capable of reflecting light to the outside of the light transmitting region 1.
Alternatively, as shown in fig. 4 and fig. 5, fig. 4 is another schematic cross-sectional structure diagram of the direction BB' in fig. 2, and fig. 5 is an enlarged structural diagram of the light reflecting layer in fig. 4, the zigzag shape includes "V" shaped structures 40 arranged periodically, the openings of the "V" shaped structures 40 face the side of the display film layer 3, the "V" shaped structures 40 include a first side L1 close to the light transmitting region 1 and a second side L2 far away from the light transmitting region 1, wherein an included angle α 1 between the first side L1 and the plane of the display panel is larger than an included angle α 2 between the second side L2 and the plane of the display panel.
Specifically, since it is desired to reduce the light emitted from the light emitting device 30 and reflected to the light transmitting region 1, the angle α 1 between the first side L1 near the light transmitting region and the plane of the display panel is set to be large, so that the light emitted from the light emitting device 30 can be reflected at the first side L1 at a large angle to the side away from the light transmitting region 1; in addition, the angle α 2 between the second side L2 far away from the light-transmitting region and the plane of the display panel is small, so that more light emitted from the light-emitting device 30 is emitted to the first side L1. Note that, in the embodiment of the present invention, α 1 and α 2 are both smaller than 90 °. In other practical implementations, such as the structure shown in fig. 3, the angle between the first edge and the plane of the display panel may be equal to the angle between the second edge and the plane of the display panel.
Alternatively, as shown in fig. 6 and 7, fig. 6 is another schematic cross-sectional structure diagram of the direction BB 'in fig. 2, and fig. 7 is another schematic cross-sectional structure diagram of the direction BB' in fig. 2, and in a direction perpendicular to the plane of the display panel, the cross section of the light reflecting layer 4 is a circular arc-shaped structure that is periodically arranged and extends from the light transmitting region 1 to the display region 2.
Specifically, for example, in the structure shown in fig. 6, the circular arc in the cross section of the light reflecting layer 4 is convex toward the side away from the display film layer 3, and in the structure shown in fig. 7, the circular arc in the cross section of the light reflecting layer 4 is convex toward the side close to the display film layer 3.
It should be noted that, in the above drawings, only the example of the overall light reflecting layer 4 having the relief structure is illustrated, and this structure is relatively simple to implement in terms of process, and in other realizable modes, the light reflecting layer may have the relief structure only on the side close to the display film layer, for example, as shown in fig. 8, fig. 8 is another schematic sectional structure view along the direction BB' in fig. 2, and the side of the light reflecting layer 4 far from the display film layer 3 may have no relief structure, and only on the side of the light reflecting layer 4 close to the display film layer 3 may have the relief structure.
Optionally, as shown in fig. 8, the display panel further includes: the touch control film layer 5 is located on the light emitting side of the display film layer 3, the touch control film layer 5 comprises a touch control metal layer 50, and the reflecting layer 4 and the touch control metal layer 50 are arranged on the same layer. Thus, the touch metal layer 50 and the light reflecting layer 4 can be formed by the same patterning process, so that the cost is saved.
Optionally, a cushion layer 6 is disposed between the reflective layer 4 and the display film layer 3, and the cushion layer 6 is used for setting a suitable distance between the reflective layer 4 and the display film layer 3, so that the light reflection can be realized at an optimal angle by the relief structure on the side of the reflective layer 4 close to the display film layer 3.
Optionally, as shown in fig. 5, the undulation height of the reflective layer 4 is h, and h is greater than or equal to 0.1 μm and less than or equal to 10 μm, on one hand, a larger undulation height may result in a larger thickness of the display panel, on the other hand, a smaller undulation height may result in a poorer light reflection effect, and considering the above two aspects and the process influence, the undulation height of the reflective layer 4 is set to be between 0.1 μm and 10 μm. The width of the reflecting layer 4 from the light-transmitting area 1 to the display area 2 is n, and n is more than or equal to 1 mu m and less than or equal to 5 mm.
Optionally, as shown in fig. 3, the display panel further includes: the rigid cover plate layer 71 between the light emitting device 30 and the light reflecting layer 4, that is, the embodiment of the present invention is suitable for a rigid organic light emitting display panel.
Optionally, as shown in fig. 4, the display panel further includes: the flexible encapsulation layer 72 between the light emitting device 30 and the light reflecting layer 4, i.e., the embodiment of the present invention is also applicable to a flexible organic light emitting display panel.
In addition, in the embodiment of the present invention, the light emitting device 30 is not disposed in the light-transmitting edge region 11, so as to save cost, because the light-emitting side of the display film layer 3 is already disposed with the light-reflecting layer 4 in the light-transmitting edge region 11, the function of displaying a picture cannot be realized in this region.
As shown in fig. 9, fig. 9 is a schematic structural diagram of a display device according to an embodiment of the present invention, and the embodiment of the present invention further provides a display device including the display panel 100.
Specifically, the specific structure of the display panel 100 is the same as that of the above embodiments, and is not described herein again. The display device can be any electronic equipment with a display function, such as a mobile phone, a tablet computer, a notebook computer, an electronic paper book or a television.
In the display device in the embodiment of the invention, the light-emitting side of the display film layer is provided with the reflecting layer, the reflecting layer is positioned between the display area and the light-transmitting area, when light is emitted towards one side of the light-transmitting area, the part of light can be emitted to the surface of the reflecting layer close to the display film layer, and the surface of the reflecting layer close to one side of the display film layer is of the fluctuation structure, so that the surface facing the other side of the light-transmitting area is arranged in the fluctuation structure, when the light irradiates the surface, the direction of the reflected light can be changed, more reflected light can be emitted towards the direction deviating from the light-transmitting area, the light reflected to the light-transmitting area is reduced, and the adverse effect caused by the fact that pixel light is reflected to the photosensitive unit of the light-transmitting area.
Optionally, the display device further includes: an optical member 200, i.e., a photosensitive unit, is disposed corresponding to the light transmission region 1 of the display panel 100.
