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 only a part of the embodiments of the present invention, and not all of the embodiments. All other embodiments, which can be obtained by a person skilled in the art based on the embodiments of the present invention without any creative work, belong to the protection scope of the present invention.
Fig. 1 is a schematic cross-sectional structural view of a display panel according to an embodiment of the present invention, as shown in fig. 1, the display panel includes: a first surface 10 and a second surface 20 which are oppositely arranged, wherein the first surface 10 comprises a first frame area 101, and the second surface 20 comprises a second frame area 201;
the imaging module 30, the imaging module 30 is located between the first surface 10 and the second surface 20, and is disposed inside the display panel; a first end of the first optical waveguide 41 is located in the first frame region 101, and is configured to receive at least a portion of external light incident to the first frame region 101, and a second end of the first optical waveguide 41 corresponds to an imaging surface of the imaging module 30, and is configured to transmit the external light received by the first end of the first optical waveguide 41 to the imaging surface of the imaging module 30; a second optical waveguide 42, a first end of the second optical waveguide 42 is located in the second frame region 201, and is configured to receive at least a portion of the external light incident to the second frame region 201, and a second end of the second optical waveguide 42 corresponds to an imaging surface of the imaging module 30, and is configured to transmit the external light received by the first end of the second optical waveguide 42 to the imaging surface of the imaging module 30; the imaging module 30 is configured to image the object on the side of the first surface 101 away from the second surface 201 or the object on the side of the second surface 201 away from the first surface 101 according to the light transmitted by the first optical waveguide 41 or the second optical waveguide 42.
It can be understood that the first surface 10 and the second surface 20 of the display panel may correspond to a light emitting surface and a back surface of the display panel, respectively, or the first surface 10 and the second surface 20 may correspond to a back surface and a light emitting surface of the display panel, respectively, or both the first surface 10 and the second surface include the light emitting surface of the display panel, which is not limited in the embodiment of the present invention. Taking the first surface 10 as a light emitting surface and the second surface as a back surface as an example, the first surface 10 includes a first frame area 101, and the second surface 20 includes a second frame area 201, it can be understood that the first surface 10 further includes a display area except the first frame area 101, and a display screen (not shown in the figure) is correspondingly disposed in the display area.
The specific shape and material of the first optical waveguide 41 and the second optical waveguide 42 are not limited in the embodiments of the present invention. For example, the first optical waveguide 41 and the second optical waveguide 42 are made of an optical glass material or a resin optical material, and the first end and the second end of the first optical waveguide 41 and the first end and the second end of the second optical waveguide 42 have a polygonal or circular cross-section.
The specific type and material of the imaging module 30 are not limited in the embodiment of the present invention, and the imaging module 30 may be disposed at any position inside the display panel without affecting the display of the display panel.
Specifically, the first end of the first optical waveguide 41 is located in the first frame area 101, and when the external light enters the first frame area 101 of the first surface 10, the first end of the first optical waveguide 41 receives the external light, transmits the light to the second end of the first optical waveguide 41, and emits the light to the imaging surface of the imaging module 30 from the second end, so that the imaging surface of the imaging module 30 receives the light emitted from the second end of the first optical waveguide 41, and then images an object on a side of the first surface 101 away from the second surface 201. Based on the same principle, the first end of the second optical waveguide 42 is located in the second frame area 201, and when the external light enters the second frame area 201 of the second surface 20, the first end of the second optical waveguide 42 receives the external light, transmits the light to the second end of the second optical waveguide 42, and emits the light to the imaging surface of the imaging module 30 from the second end, so that the imaging surface of the imaging module 30 receives the light emitted from the second end of the second optical waveguide 42, and then images the object on the side of the second surface 201 away from the first surface 101. It can be understood that, after being injected into the first optical waveguide 41 or the second optical waveguide 42, the external light may be emitted from the second end of the first optical waveguide 41 or the second optical waveguide 42 through total internal reflection, and during the transmission process, the light is hardly attenuated, so that the image of the object finally presented on the imaging surface of the imaging module 30 is clear and has high brightness. Further, set up imaging module 30 between first surface 10 and second surface 20, need not to set up imaging module on display panel's surface, can greatly improve display panel's screen and account for the screen accounts for and is close 100%, and then makes display panel's outward appearance simple more, pleasing to the eye, improves user's use and experiences.
Alternatively, and with continued reference to FIG. 1, the imaging surface of the imaging module 30 faces a sidewall between the first surface 10 and the second surface 20.
Specifically, considering that the first optical waveguide 41 and the second optical waveguide 42 need a certain light transmission path, the structures of the first optical waveguide 41 and the second optical waveguide 42 can be bent adaptively, so that the second end of the first optical waveguide 41 and the second end of the second optical waveguide 42 are perpendicular to the first surface 10 and the second surface 20, i.e. parallel to a certain sidewall between the first surface 10 and the second surface 20, and thus, the imaging plane of the imaging module 30 faces the certain sidewall between the first surface 10 and the second surface 20 and corresponds to the second end of the first optical waveguide 41 and the second end of the second optical waveguide 42, so as to reduce the overall thickness of the display panel, which is beneficial to the light and thin design of the display panel.
It will be appreciated that depending on the specific positions of the second end of the first optical waveguide 41 and the second end of the second optical waveguide 42 in the display panel, the side wall of the imaging plane of the imaging module 30 facing between the first surface 10 and the second surface 20 may be any side wall around the edge of the display panel, or the entire side wall around the edge of the display panel.
Optionally, with continued reference to fig. 1, the perpendicular projection of the second surface 20 on the first surface 10 coincides with the first surface 10; a perpendicular projection of the first end of the first optical waveguide 41 on the first surface 10 at least partially overlaps a perpendicular projection of the first end of the second optical waveguide 42 on the first surface 10.
Specifically, the first surface 10 and the second surface are disposed oppositely, the first surface 10 and the second surface are generally disposed in parallel, and the perpendicular projection of the second surface 20 on the first surface 10 is coincident with the first surface 10, i.e. both are the same size. The first end of the first optical waveguide 41 is located in the first frame region 101 of the first surface 10, the first end of the second optical waveguide 42 is located in the second frame region 201 of the second surface 20, and the first end of the first optical waveguide 41 and the first end of the second optical waveguide 42 may be parallel to the first surface 10 or inclined at a certain included angle. Since the first frame region 101 and the second frame region 201 are both located at the edge of the display panel, the perpendicular projection of the first end of the first light waveguide 41 on the first surface 10 and the perpendicular projection of the first end of the second light waveguide 42 on the first surface 10 are arranged to at least partially overlap, on one hand, the first light waveguide 41 and the second light waveguide 42 can play a role of mutual support; on the other hand, on the premise of ensuring that the first end of the first optical waveguide 41 and the first end of the second optical waveguide 42 can receive enough external light, the sizes of the first frame region 101 and the second frame region 201 are reduced, which is beneficial to the narrow frame design of the display panel. In other embodiments, the perpendicular projection of the first end of the first optical waveguide 41 on the first surface 10 and the perpendicular projection of the first end of the second optical waveguide 42 on the first surface 10 may also be set not to overlap, for example, the first end of the first optical waveguide 41 is set at the left frame, the first end of the second optical waveguide 42 is set at the right frame, and further, the first optical waveguide 41 and the second optical waveguide 42 may be set not to overlap in the direction perpendicular to the first surface, so that the arrangement manner of the first optical waveguide 41 and the second optical waveguide 42 is more flexible, which is beneficial to implementing the lightness and thinness of the display panel.
Optionally, fig. 2 is a schematic diagram of a first surface structure of a display panel according to an embodiment of the present invention, and fig. 3 is a schematic diagram of a second surface structure of a display panel according to an embodiment of the present invention, where the first frame region 101 includes a region located around an edge of the first surface 10, and the second frame region 201 includes a region located around an edge of the second surface 20; the first end of the first optical waveguide 41 is located in all regions of the first frame region 101 and the first end of the second optical waveguide is located in all regions of the second frame region.
Specifically, referring to fig. 2, the first frame area 101 is a region located around the edge of the first surface 10, and it can be understood that, taking the first surface 10 as a light-emitting surface of the display panel as an example, the first surface 10 further includes a display area 102 surrounded by the first frame area 101. The first end of the first optical waveguide 41 is located in all regions of the first frame region 101, and it can be understood that a projection of the first end of the first optical waveguide 41 on the first surface 10 completely overlaps or at least partially overlaps with the first frame region 101, which is not limited in this embodiment of the present invention. Preferably, the projection of the first end of the first optical waveguide 41 on the first surface 10 completely overlaps with the first frame region 101, so as to sufficiently obtain external light, improve the definition of imaging, and reduce the frame size, which is beneficial to the narrow frame design of the display panel.
Similarly, with reference to fig. 3, the second frame area 201 is a region located around the edge of the second surface 20, and it can be understood that if the first surface 10 is a light emitting surface of the display panel, the second surface 20 is a back surface of the display panel. The first end of the second optical waveguide 42 is located in all the areas of the second frame area 201, so that the second optical waveguide 42 can sufficiently obtain external light, so that the image of the object appearing on the imaging surface of the imaging module 30 is clearer, the size of the frame is reduced, and the narrow frame design of the display panel is facilitated.
Optionally, fig. 4 is a schematic cross-sectional structure view of another display panel according to an embodiment of the present invention, and as shown in fig. 4, the display panel further includes a transparent frame 50, and the transparent frame 50 covers the first end of the first optical waveguide 41 and the first end of the second optical waveguide 42.
Specifically, the transparent frame 50 includes, but is not limited to, Polyethylene terephthalate (PET) or Polyimide (PI), the transparent frame 50 includes a first frame region 101, a second frame region 201, and sidewalls of the display panel, and can cover the first end of the first optical waveguide 41 and the first end of the second optical waveguide 42 to protect the first end of the first optical waveguide 41 and the first end of the second optical waveguide 42, and external light can enter the first end of the first optical waveguide 41 and the first end of the second optical waveguide 42 through the transparent frame without affecting the imaging of the object.
It should be noted that, in the case that the transparent frame 50 covers the first end of the first light waveguide 41 and the first end of the second light waveguide 42, the smaller the size of the transparent frame 50, the better, so as to further improve the screen occupation ratio of the display panel.
Optionally, fig. 5 is a schematic cross-sectional structure view of another display panel according to an embodiment of the present invention, and as shown in fig. 5, the display panel further includes a first lens group 61, where the first lens group 61 is located at a first end and/or a second end of the first optical waveguide 41, and is used for coupling external light into the first optical waveguide 41 and/or coupling light output by the first optical waveguide 41 into the imaging module 30.
It will be appreciated that fig. 5 only shows an exemplary configuration of the first lens group 61 at the first and second ends of the first optical waveguide 41. The first lens group 61 includes, but is not limited to, a spherical lens, an aspherical lens, a free-form surface lens, a diffractive optical lens, or the like, and the specific material of the first lens group 61 is not limited in the embodiments of the present invention, for example, a glass lens.
Specifically, after entering the first lens assembly 61 located at the first end of the first optical waveguide 41, the external light is refracted and coupled into the first optical waveguide 41, then reflected by the reflection surface inside the first optical waveguide 41, enters the first lens assembly 61 at the first end of the first optical waveguide 41 again, and is refracted by the first lens assembly 61 again to output the light, and finally coupled into the imaging module 30, and an image of an object is displayed on the imaging surface of the imaging module 30. In this way, the first lens group 61 is adopted to finally couple light into the imaging module 30, so that an image displayed by the imaging module 30 can be clearer. It should be noted that the first lens group 61 may be disposed only at the first end of the first optical waveguide 41 or the second end of the first optical waveguide 41, and the final coupling of the external light into the imaging module 30 may also be achieved to achieve the imaging of the object.
Optionally, fig. 6 is a schematic cross-sectional structure view of another display panel according to an embodiment of the present invention, and as shown in fig. 6, the display panel further includes a second lens group 62, where the second lens group 62 is located at a first end and/or a second end of the second optical waveguide 42, and is used for coupling external light into the second optical waveguide 42 and/or coupling light output by the second optical waveguide 42 into the imaging module 30.
It will be appreciated that fig. 6 is merely exemplary of the structure of the second lens group 62 at the first and second ends of the second optical waveguide 42. The second lens group 62 includes, but is not limited to, a spherical lens, an aspherical lens, a free-form surface lens, a diffractive optical lens, or the like, and the specific material of the second lens group 62 is not limited in the embodiments of the present invention, for example, a glass lens.

In this way, the second lens group 62 is used to couple light into the imaging module 30, so that the image displayed by the imaging module 30 is clearer. It should be noted that the second lens group 62 may be disposed only at the first end of the second optical waveguide 42 or the second end of the second optical waveguide 42, and the final coupling of the external light into the imaging module 30 may also be achieved to achieve the imaging of the object.
Optionally, fig. 7 is a schematic cross-sectional structure diagram of another display panel provided in an embodiment of the present invention, as shown in fig. 7, the display panel further includes a first optical switch 71 and a second optical switch 72, where the first optical switch 71 is located at the first end of the first optical waveguide 41, the second optical switch 72 is located at the first end of the second optical waveguide 42, when the first optical switch 71 is turned on and the second optical switch 72 is turned off, the imaging module 30 images an object on a side of the first surface 10 away from the second surface 20, and when the first optical switch 71 is turned off and the second optical switch 72 is turned on, the imaging module 30 images an object on a side of the second surface 20 away from the first surface 10.
