The technical solutions disclosed in the embodiments of the present invention are described in detail below with reference to the accompanying drawings.

As shown in fig. 1, an embodiment of the present invention discloses an electronic device, which specifically includes a display module 100 and a camera module 200.

The display module 100 may specifically include a first substrate 110, a second substrate 120, and a routing structure 130, wherein the first substrate 110 and the second substrate 120 are stacked, and the routing structure 130 is disposed on a side of the second substrate 120 facing the first substrate 110. The first substrate 110 and the second substrate 120 may be glass plates, and the second substrate 120 may be provided with a thin film transistor. The routing structure 130 may be an annular structure, and the routing structure 130 is provided with a first light through hole through which light can pass, so that light in an external environment can enter the camera module 200. The display module 100 may further include a light emitting portion 140, a transparent cover plate 150, an optical adhesive 160, a polarizer 170, and a foam 180, wherein: the light emitting part 140 may be disposed between the first substrate 110 and the second substrate 120, and the light emitting part 140 may be an organic light emitting layer; the polarizer 170 may be disposed on a surface of the first substrate 110 facing away from the second substrate 120; the transparent cover 150 is located on a side of the first substrate 110 away from the second substrate 120, and the transparent cover 150 may be connected to the polarizer 170 through an optical adhesive 160; the foam 180 can be arranged on one side of the second substrate 120 deviating from the first substrate 110, the foam 180 can be bonded with the second substrate 120, a dodging hole can be formed in the foam 180, at least one part of the camera module 200 can be located in the dodging hole, and therefore the parasitic light in the display module 100 is prevented from influencing the normal work of the camera module 200, meanwhile, the space occupied by the camera module 200 can be reduced, and the thickness of the electronic equipment is reduced.

The camera module 200 may specifically include a camera body 210 and a light shielding layer 220, the camera body 210 is provided with a light inlet 211, the second substrate 120 is located between the first substrate 110 and the camera body 210, the light shielding layer 220 is located between the first substrate 110 and the second substrate 120, and the light shielding layer 220 is provided with a second light inlet. The camera body 210 may specifically include a bracket 212, a lens assembly and a photo sensor chip 213, where the lens assembly is disposed on the bracket 212, and the lens assembly may include lenses such as a convex lens and a concave lens to achieve the effects of converging light; the photosensitive chip 213 may be disposed in the support 212, the photosensitive chip 213 has a photosensitive area for photosensitive, and the photosensitive chip 213 may convert the optical signal into an electrical signal, so as to obtain corresponding image information. The second light through hole is also used for light to pass through, so that light in the external environment can enter the camera module 200 and reach the photosensitive area of the photosensitive chip 213, thereby realizing the shooting function.

Above-mentioned walk line structure 130 and light shield 220 and all can play the effect of shading, and above-mentioned first logical unthreaded hole, second logical unthreaded hole and light inlet 211 arrange on camera module 200's optical axis direction, and consequently light among the external environment can pass second logical unthreaded hole and first logical unthreaded hole, finally gets into camera module 200 through light inlet 211 in for camera module 200 can realize shooting the function. The orthographic projection of the second light passing hole on the surface perpendicular to the optical axis direction of the camera module 200 is located in the orthographic projection of the light entering hole 211 on the surface perpendicular to the optical axis direction. That is, when viewed in the optical axis direction of the camera module 200, the contour size of the second light passing hole is smaller than the contour size of the light entering hole 211. The size of the light inlet 211 is slightly larger, so that the screen occupation ratio of the display module 100 is not affected, and light rays in the external environment can be ensured to enter the camera module 200 as much as possible. The second light through hole may affect the screen occupation ratio of the display module 100, so that the second light through hole may be set as small as possible on the premise of meeting the shooting requirement of the camera module 200, thereby reducing the occupation ratio of the light shielding layer 220 to the display area and achieving the purpose of improving the screen occupation ratio of the electronic device.

In the electronic device, the light shielding layer 220 of the camera module 200 is disposed on the display module 100, so that on one hand, the distance between the light shielding layer 220 and the display module 100 is almost zero, and thus the first light passing hole can be smaller; on the other hand, there is no assembly error between the display module 100 and the light shielding layer 220, so the assembly error does not need to be considered when the first light through hole is formed, and the size of the first light through hole can be further reduced, so that the screen occupation ratio of the electronic device is higher. Meanwhile, after the size of the first light through hole is reduced, the appearance texture of the electronic equipment is improved, and the user experience is improved accordingly.

In an alternative embodiment, the light shielding layer 220 may be disposed on a surface of the second substrate 120 facing the first substrate 110, such that the light shielding layer 220 is located between the first substrate 110 and the second substrate 120. Because the area of the second substrate 120 is relatively large and the structural strength thereof is high, the embodiment can facilitate the forming of the light shielding layer 220, and simultaneously can optimize the forming quality of the light shielding layer 220, so that the light shielding effect of the light shielding layer 220 is better.

Further, the light shielding layer 220 and the routing structure 130 may be integrally disposed, so that the light shielding layer 220 and the routing structure 130 can be simultaneously obtained by one-step molding process. Relatively speaking, when the light shielding layer 220 and the routing structure 130 are integrally arranged, the forming process of the electronic device is simpler, the cost is lower, and the light shielding layer 220 and the routing structure 130 are not easy to dislocate, so that the whole light shielding area is not easy to enlarge.

In another alternative embodiment, the light shielding layer 220 may be disposed on a side surface of the routing structure 130 facing the first substrate 110, so that the light shielding layer 220 is located between the first substrate 110 and the second substrate 120. For example, the trace structure 130 may be formed on a surface of the second substrate 120 facing the first substrate 110, and then the light-shielding layer 220 may be formed on a surface of the trace structure 130 facing the first substrate 110. In this structure, the light shielding layer 220 and the routing structure 130 can be distributed along the optical axis direction of the camera module 200, that is, the light shielding layer and the routing structure are stacked, so that the light shielding effects generated by the light shielding layer and the routing structure can be superposed, thereby exerting a better light shielding effect.

In other embodiments, the routing structure 130 may be disposed on a side surface of the light-shielding layer 220 facing the first substrate 110, so that the light-shielding layer 220 is located between the first substrate 110 and the second substrate 120. For example, the light shielding layer 220 may be formed on a surface of the second substrate 120 facing the first substrate 110, and then the routing structure 130 may be formed on a surface of the light shielding layer 220 facing the first substrate 110. Similarly, in this structure, the light-shielding layer 220 and the routing structure 130 can be distributed along the optical axis direction of the camera module 200, that is, they are stacked, so that the light-shielding effects generated by the two can be superimposed, thereby exerting a better light-shielding effect.

In addition, when the light shielding layer 220 and the routing structure 130 are stacked, the light shielding layer 220 and the routing structure 130 are in direct contact, so that the space occupied by the routing structure 130 and the light shielding layer 220 is smaller, and the overall thickness of the display module is reduced.

Alternatively, the orthographic projection of the light entrance hole 211 on the plane perpendicular to the aforementioned optical axis direction may be located within the orthographic projection of the first light entrance hole on the plane perpendicular to the optical axis direction, but in order to make the screen occupation ratio of the electronic apparatus higher, the orthographic projection of the first light entrance hole on the plane perpendicular to the optical axis direction may be located within the orthographic projection of the light entrance hole 211 on the plane perpendicular to the optical axis direction. At this time, the size of the first light passing hole is further reduced, thereby achieving the aforementioned object.

Since the first light-passing hole and the second light-passing hole affect the screen ratio of the display module 100, the first light-passing hole and the second light-passing hole can be set as small as possible. In an alternative embodiment, an orthographic projection of the first light passing hole on a plane perpendicular to the optical axis direction of the camera module 200 and an orthographic projection of the second light passing hole on a plane perpendicular to the optical axis direction may coincide. In other words, the shape of the first light passing hole is the same as that of the second light passing hole, and the two light passing holes have the same size. So set up and to make the size of first light hole and second light hole all as little as possible, can also make relative position between them can refer to each other when shaping display module assembly 100 simultaneously to be more convenient for process display module assembly 100.

The embodiment of the utility model provides an in, the outline shape of walking line structure 130 and light shield layer 220 can set up in a flexible way, and for example this outline shape can be rectangle, circular, oval, and simultaneously, the shape of first logical unthreaded hole and second logical unthreaded hole also can select in a flexible way, for example can be rectangular hole, round hole, oval hole etc.. In an optional embodiment, considering that the shape of the field range of the camera module 200 is generally circular, in order to adapt the camera module 200, thereby further increasing the screen occupation ratio of the electronic device, the routing structure 130 and the light shielding layer 220 may be set to be circular ring structures, and the radial width of the light shielding layer 220 may be smaller than the radial width of the routing structure 130, so as to prevent the situation that the light shielding area is too large due to too large radial width of the light shielding layer 220, thereby achieving the aforementioned purpose.

Referring to fig. 1, H is a size of a hole that cannot be used for displaying on the external appearance surface of the display module 100, a is an aperture of the second clear hole (or an aperture of the first clear hole), and D is a width of the routing structure 130, since the field angle β of the camera module 200 is a fixed value, a is substantially a fixed value, and D is substantially a fixed value.

In order to improve the shooting effect of the camera module 200, the distance between the focus of the camera body 210 and the light shielding layer 220 in the optical axis direction can be a preset value. That is, when the position of the light shielding layer 220 changes, the position of the camera body 210 changes accordingly, so as to ensure that the focus of the camera body 210 and the light shielding layer 220 maintain the mutually matched position, thereby achieving the purpose of improving the shooting effect. The embodiment of the utility model provides an in, because the light shield layer 220 shifts up to in the display module assembly 100, consequently the distance between camera body 210 and the display module assembly 100 can further reduce for the distribution of display module assembly 100 and camera module assembly 200 is compacter, thereby more is favorable to piling up of spare part in the electronic equipment.

The above-mentioned forming method of the light-shielding layer 220 has various embodiments, and in an optional embodiment, the light-shielding layer 220 may be formed by a plating process, that is, the light-shielding layer 220 may be a plated structure, which is convenient for forming, and the formed light-shielding layer 220 has a smaller thickness, thereby being more beneficial to controlling the thickness of the electronic device. Of course, the light-shielding layer 220 may also be formed by other processes, such as a printing process, so that the light-shielding layer 220 is a printed structure.

When the electronic Device is assembled, the light shielding layer 220 and the camera body 210 can be aligned and fixed in a manner of accurate positioning of a CCD (Charge-coupled Device) camera, dynamic alignment adjustment of the micro motor driving camera module 200 and the like, so that the relative position precision of the light shielding layer 220 and the camera body 210 is higher, the imaging effect of the camera module 200 is ensured, the size of the first light through hole is increased without considering alignment errors, and the screen occupation ratio of the electronic Device can be improved.

The embodiment of the utility model provides a disclosed electronic equipment can be for smart mobile phone, panel computer, electronic book reader or wearable equipment. Of course, the electronic device may also be other devices, and the embodiment of the present invention does not limit this.
