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 application.

It is to be understood that the data so used is interchangeable under appropriate circumstances such that the embodiments of the application are capable of operation in sequences other than those illustrated or described herein. In addition, "and/or" in the specification and claims means at least one of connected objects, a character "/", and generally means that the former and latter related objects are in an "or" relationship.
The electronic device provided in the embodiments of the present application is described in detail with reference to the accompanying drawings through specific embodiments and application scenarios thereof.
Referring to fig. 1 and fig. 2, an embodiment of the present application discloses an electronic device, which includes a display module and a camera module 500.
The display module is used for displaying information such as images and characters of the electronic equipment. The display module includes a transparent cover plate 100 and a display layer 400, and the transparent cover plate 100 and the display layer 400 are stacked. At this time, the light-transmissive cover plate 100 covers the surface of the display layer 400. The transparent cover plate 100 can be used to protect the display layer 400 and enable the display module to have better display performance. Alternatively, the transparent cover plate 100 may be made of a transparent plastic or a transparent glass.
The camera module 500 is used to implement a shooting function of the electronic device. The camera module 500 is disposed on a side of the display layer 400 departing from the transparent cover plate 100.
The display layer 400 has a light-transmitting area 410 and a display area 420. The display area 420 is used for displaying information such as images and characters of the electronic device. The light transmittance of the light transmissive region 410 is greater than that of the display region 420, so that external light can enter the camera module 500 through the display region 420.
The display region 420 is disposed around the light-transmitting region 410, and the light-transmitting region 410 has a light-entering surface and a light-emitting surface opposite to each other, and it should be noted that the light-entering surface and the light-emitting surface are both solid structures, that is, the light-transmitting region 410 is a non-opening structure. The light inlet surface is disposed opposite to the transparent cover plate 100, and the light outlet surface is disposed opposite to the camera module 500.
In a specific operation process, the external light firstly passes through the transparent cover plate 100, then the light enters the display layer 400 from the light entrance surface, and then exits the display layer 400 from the light exit surface, and finally the light enters the camera module 500.
The display module has a diaphragm 700, and the diaphragm 700 has a through hole disposed opposite to the light-transmitting region 410. As can be known from the prior art, the diaphragm 700 is used to limit the field range of the camera module 500, and therefore, the detailed structure and function of the diaphragm 700 are not described herein.
In the embodiment of the present application, the light-transmitting area 410 has a light-emitting surface and a light-entering surface that are opposite to each other, the light-entering surface is opposite to the light-transmitting cover plate 100, and the light-emitting surface is opposite to the camera module 500. At this time, the light-transmitting region 410 has a non-open structure. For the light-transmitting area 410 having an opening structure, the lens end surface of the camera module 500 is not limited by the opening, so that the diameter of the lens end surface of the camera module 500 can be designed to be larger, and the electronic device has better shooting performance.
The diaphragm 700 is disposed in the display module, and the diaphragm 700 is used for limiting the field range of the camera module 500. At this time, the distance between the image principal point of the camera module 500 and the light-transmitting cover plate 100 is reduced, so that on the premise that the shooting field angle of the camera module 500 is the same, the diameter of the field of view of the camera module 500 is reduced, the area of the light-transmitting area 410 is correspondingly reduced, the area of the display area 420 is increased, and the screen area ratio of the electronic device is increased.
In addition, light-transmitting area 410 is the structure of not opening a hole, so electronic equipment's display module assembly is under the screen state of breathing, and display area 420 that the user saw and light-transmitting area 410 are a whole, and display area 420 and light-transmitting area 410 do not have obvious split sense to make display module assembly's appearance quality better, and then improved electronic equipment's appearance quality.
In addition, the light-transmitting region 410 is a non-open structure, so that the display layer 400 is an integral structural member, and the display layer 400 has better mechanical properties, so that the strength of the display layer 400 is higher.
The main point of the camera module 500 mentioned above is the intersection point of the perpendicular line between the photographing center and the image plane. It should be noted that the light-transmitting area 410 is only a part of the non-display area of the display module, and the non-display area further includes the light-shielding portion 210 and the trace portion 430.
In the above embodiment, the display module may further include a polarizer 300 and an optical adhesive layer 200, and the transparent cover plate 100, the optical adhesive layer 200, the polarizer 300 and the display layer 400 are sequentially stacked. The polarizer 300 can improve the optical performance of the display module. Meanwhile, the transparent cover plate 100 and the polarizer 300 can be connected by the optical adhesive layer 200, and the optical adhesive layer 200 has better light transmittance, so that the optical performance of the display module is not affected, and meanwhile, the connection stability can be improved.
The stop 700 may be disposed between the transparent cover plate 100 and the optical adhesive layer 200, or the stop 700 may be disposed between the optical adhesive layer 200 and the polarizer 300, or the stop 700 may be disposed between the polarizer 300 and the display layer 400, or the stop 700 may be embedded in the optical adhesive layer 200. Of course, the stop 700 may be disposed at other positions of the display module, and is not limited herein.
In another alternative embodiment, the display layer 400 may be provided with a wire portion 430, the wire portion 430 is disposed around the light-transmitting region 410, and the wire portion 430 is electrically connected to the display region 420. The wire portion 430 is used for transmitting a display signal of the display module, and the wire portion 430 is electrically connected to a device for displaying an image on the display area 420, for example, the wire portion 430 is electrically connected to a device such as a thin film transistor.
In this scheme, walk line portion 430 and can play the effect of shading to the edge of light transmission area 410 to prevent the parasitic light scattering, and then improve electronic equipment's shooting performance.
In the above embodiments, the optical adhesive layer 200 may be disposed between the transparent cover 100 and the display layer 400, and the aperture 700 may be disposed between the display layer 400 and the optical adhesive layer 200. At this time, the diaphragm 700 may overlap the routing portion 430, and at this time, the stacking thickness of the diaphragm 700 and the routing portion 430 is larger, so that a larger gap needs to be reserved between the optical adhesive layer 200 and the display layer 400. In this regard, in an alternative embodiment, the aperture 700 may be located between the layer of optical glue 200 and the light-transmissive cover plate 100. At this time, the gap between the optical adhesive layer 200 and the display layer 400 is reduced, thereby enabling the display layer 400 to be more closely connected with the optical adhesive layer 200. The aperture 700 is positioned between the optical adhesive layer 200 and the transparent cover 100, and can prevent the wiring portion 430 from interfering with the electronic components in the display region 420.
In order to prevent light leakage at the edge of the light-transmitting region 410, the shooting performance of the camera module 500 is affected. In another alternative embodiment, a light shielding portion 210 is disposed between the light-transmissive cover plate 100 and the optical adhesive layer 200, and the light shielding portion 210 is disposed around the light-transmissive region 410. At this time, the light shielding portion 210 can prevent light leakage at the edge of the light transmission region 410, thereby improving the photographing performance of the camera module 500.
Further, an aperture 700 may be provided on an inner circumferential surface of the light shielding portion 210, and in this case, the light shielding portion 210 corresponds to the aperture 700.
In this scheme, the diaphragm 700 is integrated on the light-blocking portion 210, so that the installation position of the diaphragm 700 does not need to be reserved at other positions of the display module, and the size of the display module is smaller, thereby making the size of the electronic device smaller.
Optionally, the light shielding portion 210 may be an ink screen printing layer, and of course, the light shielding portion 210 may also be made of other materials, which is not limited herein. Diaphragm 700 may be a ring-shaped light shielding sheet embedded on the light shielding portion 210, or an ink layer silk-screened on an inner annular surface of the light shielding portion 210, and diaphragm 700 may be disposed on the inner annular surface of the light shielding portion 210 in other manners, which is not limited herein.
In another alternative embodiment, at least a portion of the projected contour of the trace 430 may be located within the projected contour of the diaphragm 700 in a direction perpendicular to the projected direction of the transparent cover plate 100. In this scheme, at least part of the routing portion 430 can be covered by the diaphragm 700, so that the routing portion 430 is not easily exposed, and thus a user cannot easily see the routing portion, and appearance performance of the electronic device is improved.
Meanwhile, at least part of the diaphragm 700 and the wiring portion 430 are overlapped, and the protruding size of the wiring portion 430 relative to the diaphragm 700 is small, so that the area of a non-display area of the display module is further reduced, and the screen occupation ratio of the electronic device can be increased.
Compared with the above-mentioned scheme that the diaphragm 700 is arranged on the inner annular surface of the light shielding portion 210, in this scheme, the diaphragm 700 is equivalent to the light shielding portion 210, and at this time, the diaphragm 700 may be an ink screen printing layer, and of course, the diaphragm 700 may also be made of other materials, which is not limited herein.
As shown in fig. 2, the size of the non-display area is L, the size of the light-transmitting area 410 is a, the size of the aperture 700 is C, and the protruding size of the routing portion 430 with respect to the aperture 700 is D, so that L = a +2c +2d. Compared with the opening structure of the display module in the prior art, the size of the non-display area of the display module further includes the size of the lens end surface and the packaging size of the routing portion 430, so that the size of the non-display area is larger. In the present application, the size of the non-display area is the sum of the size of the light-transmitting area 410, the size of the aperture 700, and the protruding size of the wiring portion 430 with respect to the aperture 700. The light-transmitting area 410 is a non-opening structure, so that the light-transmitting area 410 can encapsulate the wiring portion 430, thereby reducing the size of the lens end face and the encapsulation size of the wiring portion 430, and further enabling the size of the non-display area to be smaller.
Note that, when the diaphragm 700 is provided at the inner annular surface of the light shielding portion 210, the above dimension C is the dimension of the light shielding portion 210.
The non-display area of the display module is an area that cannot display images or text information, and the non-display area includes the light-transmitting area 410 and other areas that cannot be displayed, for example, the routing portion 430 on the display layer 400 or the area of the display layer 400 covered by the light-shielding portion 210 and the aperture stop 700.
Further, the outer side surface of the diaphragm 700 may be flush with the outer side surface of the wiring portion 430, and at this time, in a direction perpendicular to the projection direction of the light-transmitting cover plate 100, the projection profiles of the wiring portion 430 may all be located within the projection profile of the diaphragm 700, which further improves the appearance performance of the electronic device.
In addition, the outer side surface of the diaphragm 700 may be flush with the outer side surface of the routing portion 430, that is, the protruding dimension D of the routing portion 430 with respect to the diaphragm 700 is zero, so L = a +2C. Therefore, the size of the non-display area of the display module is further reduced, and the screen occupation ratio of the electronic equipment is further increased.
In the above embodiments, the aperture 700 may be located between the transparent cover plate 100 and the optical adhesive layer 200, and at this time, the stacking height of the transparent cover plate 100, the aperture 700 and the optical adhesive layer 200 is larger, so that the thickness of the display module is larger.
Based on this, in another alternative embodiment, at least one of the transparent cover plate 100 or the optical adhesive layer 200 is provided with a receiving groove, and the diaphragm 700 is located in the receiving groove. In this scheme, the diaphragm 700 can be hidden in the accommodation groove to make the height that the printing opacity apron 100, diaphragm 700 and optical adhesive layer 200 pile up is less, and then makes the thickness of display module assembly less. In addition, the transparent cover plate 100 is tightly contacted with the optical adhesive layer 200, so that the safety and reliability of the display module can be improved.
In order to further improve the security and reliability of the display module, in another alternative embodiment, the display module may further include the support layer 600 and the polarizer 300 mentioned above, and the light-transmissive cover plate 100, the polarizer 300, the display layer 400, and the support layer 600 may be stacked in sequence. The routing part 430 may be located between the polarizer 300 and the support layer 600. The diaphragm 700 may be located between the polarizer 300 and the support layer 600.
In this scheme, supporting layer 600 is used for supporting display layer 400 to can improve display layer 400's rigidity, and then make display layer 400 be difficult to damage, and then improve display module assembly's security and reliability.
In the above embodiment, the supporting layer 600 has a better light transmittance, so that the shooting performance of the camera module 500 is not easily affected. The supporting layer 600 may be a glass plate or a resin plate, and of course, the supporting layer 600 may also be made of other materials with high light transmittance, which is not limited herein.
In another alternative embodiment, stop 700 may be located on the inner annular surface of wire running portion 430. In this case, the trace portion 430 corresponds to the aperture 700.
In this scheme, the diaphragm 700 can be integrated on the routing portion 430, so that the other positions of the display module do not need to reserve the installation position of the diaphragm 700, and further the volume of the display module is small, and the volume of the electronic device is small.
Alternatively, the diaphragm 700 may be an ink silk-screen layer applied to an inner annular surface of the routing portion, or may have another structure, which is not limited herein.
As shown in fig. 1, the size of the non-display area of the display module is the size of the light-transmitting area 410 plus the size of the wire portion 430, the size of the non-display area is L, the size of the light-transmitting area 410 is a, and the size of the wire portion 430 is 2B, so that L = a +2B. Compared with the structure of the opening of the display module in the background art, the size of the non-display area of the display module also includes the size of the lens end face, so the opening is larger. In the present application, the diaphragm 700 is disposed on the inner annular surface of the routing portion 430, and the size of the non-display area is the size of the light-transmitting area 410 plus the size of the routing portion 430, so that the size of the lens end surface is reduced, and further the size of the non-display area is smaller.
Optionally, the size that the size of the non-display area of display module assembly can set up is the same with the size of the icon that the display module assembly shows, and then can further improve electronic equipment's screen and account for than. For example, the size of the non-display area is the same as that of the signal icon or the power icon.
In another alternative embodiment, both the display layer 400 and the support layer 600 may be flexible structures. In this scheme, display layer 400 and supporting layer 600 are flexible structure, and display layer 400 can bend or curl with supporting layer 600 to can realize the rolling of display area 420, and then can adjust the size of display area 420 of display module assembly according to user's demand, and then improve electronic equipment's performance. The flexible structure in the above is a member that can be bent or curled. For example, the display layer 400 and the supporting layer 600 may be made of flexible materials such as plastic.
In another alternative embodiment, the wire traces 430 may be disposed between the display region 420 and the light-transmitting region 410, that is, the wire traces 430 are embedded in the display layer 400. The routing portion 430 may include a first surface and a second surface that are opposite to each other, where the first surface is flush with the light inlet surface, and the second surface is flush with the light outlet surface. In this embodiment, the first surface and the light-entering surface of the trace portion 430 and the upper surface of the display area 420 form a complete plane. The second surface and the light-emitting surface of the wire trace part 430 and the lower surface of the display region 420 form a complete plane. At this time, the trace portion 430 does not protrude from the light-transmitting area 410 and the display area 420, and a recess is not formed at the position where the trace portion 430 is located, so that the reliability of the display module is higher.
To further improve the shooting performance of the electronic device. In another alternative embodiment, the polarizer 300 may be provided with a light hole, and the light hole is disposed opposite to the light-transmitting region 410 and the through hole. In this scheme, the light hole has been seted up to polaroid 300 and the relative position of printing opacity district 410 to can improve the luminousness of the position that polaroid 300 and printing opacity district 410 correspond, and then make the light that gets into camera module 500 increase, and then make the image that electronic equipment shot more clear, further improve electronic equipment's shooting nature.
In the above embodiments, the polarizer 300 is provided with the light hole, so that the mechanical property of the opening of the polarizer 300 is reduced, the supporting force at the light hole is weaker, and the reliability of the display module is poorer. Based on this, in another alternative embodiment, the side of the optical adhesive layer 200 facing the polarizer 300 may be provided with an optical adhesive filling protrusion 220, and the optical adhesive filling protrusion 220 may be filled in the light-transmitting hole. The scheme can increase the supporting force at the position of the light-transmitting hole and cannot influence the light-transmitting performance of the display module.
Further, the optical adhesive filling protrusion 220 and the optical adhesive layer 200 may be an integral structure. In this scheme, the optical cement filling convex part 220 and the optical cement layer 200 are integrally formed, so that the manufacturing process of the display module is simplified, and the display module is simple to manufacture. In addition, the optical cement filling convex part 220 and the optical cement layer 200 are integrally formed, so that the optical cement filling convex part 220 is not easy to fall off from the optical cement layer 200, and the safety and the reliability of the display module are improved.
