Detailed Description
In order to make the objects, technical solutions and advantages of the present invention more apparent, the technical solutions of the present invention will be clearly and completely described below with reference to the specific embodiments of the present invention and the accompanying drawings. It is to be understood that the described embodiments are merely exemplary of the invention, and not restrictive of the full scope of the 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 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 may specifically include a display screen and an optical device 300, where the display screen may include a display module 100 and a backlight module 200. The display module 100 may include a transparent cover plate 110 and a display screen main body 120, which may be bonded and fixed by bonding or the like. The backlight module 200 is connected to the display module 100, the backlight module 200 may be located at a side of the display screen main body 120 away from the transparent cover plate 110, and the backlight module 200 may emit light to perform display by cooperating with the display module 100. The optical device 300 is located below the display module 100, and the optical device 300 may include at least one of a camera, a sensor, and a fill-in light. When the optical device 300 includes a camera, the camera includes a bracket 310 and a camera body 320, and the camera body 320 is mounted through the bracket 310. Of course, the optical device 300 may also include other devices, which are not limited herein.
In an alternative embodiment, the backlight module 200 may include a light source (not shown), a frame 210 and a light guide plate 220. The light source may emit light, the frame 210 may serve as a base for mounting the light source and the light guide plate 220, and the frame 210 may be made of a metal material. The edge portion of the light guide plate 220 is disposed in the frame 210, and other portions of the light guide plate 220 can be located outside the frame 210, so that light emitted from the light source can be guided out to the display module 100 through the light guide plate 220.
As described above, the optical device 300 is located below the display module 100, so as to improve the screen ratio of the electronic device. Since the backlight module 200 is attached to the display module 100, in order to facilitate light rays in an external environment to enter the optical device 300 or facilitate light emitted by the optical device 300 to reach the external environment, the backlight module 200 is provided with the light through hole 230, the light through hole 230 penetrates through the frame 210, and at least a part of the optical device 300 is located in the light through hole 230, so that the light rays can be transmitted between the external environment and the optical device 300 through the light through hole 230.
The cross-sectional area of the light passing hole 230 decreases in a direction approaching the display module 100. In other words, the end of the light hole 230 away from the display module 100 is a first end, and the other end is a second end, and the cross-sectional area of the light hole 230 decreases in the direction from the first end to the second end, where the cross-section is perpendicular to the axial direction of the light hole 230. In other words, the light passing hole 230 becomes smaller and smaller in the direction approaching the display module 100. After the arrangement, the distance between the optical device 300 and the inner surface of the light through hole 230 is increased, if the electronic device falls or collides, the backlight module 200 is not easy to collide with the optical device 300, so that the optical device 300 is not easy to damage, the working quality of the optical device 300 is ensured, and the service life of the optical device is prolonged. Meanwhile, the size of the second end of the light passing hole 230 may be appropriately reduced, so that the screen occupation ratio of the electronic device is further improved.
After the backlight module 200 opens the light-passing hole 230, the light guide plate 220 can be exposed in the light-passing hole 230, that is, the light-passing hole 230 includes a first hole section opened in the frame 210 and a second hole section opened in the light guide plate 220. However, when so arranged, light entering the light guide plate 220 is likely to leak out through the light passing hole 230, thereby interfering with the normal operation of the optical device 300. To solve this problem, the frame 210 is provided with the light hole 230, and the light guide plate 220 is provided with a through hole 221, wherein the through hole 221 surrounds the light hole 230. In other words, the light guide plate 220 is not exposed at the light passing hole 230, thereby preventing light from leaking out to interfere with the optical device 300. The through hole 221 may be a cylindrical hole, and the size of the through hole 221 is larger at this time, which is not beneficial for the light guide plate 220 to guide light, so that the cross-sectional area of the through hole 221 is reduced in a direction close to the display module 100 (i.e. in a direction in which the first end of the light through hole 230 points to the second end), where the cross-section is perpendicular to the axial direction of the light through hole 230.
In an alternative embodiment, the inner surface of the light passing hole 230 may be a tapered surface, and the processing process of the light passing hole 230 is relatively simple. Of course, as shown in fig. 2, the inner surface of the light hole 230 may also be a stepped surface, and this structure may increase the structural strength of the light hole 230 while forming a hole. Similarly, the inner surface of the through hole 221 may be a tapered surface or a stepped surface.
Too large a change in the cross-sectional area of the light passing hole 230 may result in a decrease in the structural strength of the frame 210; conversely, if the cross-sectional area of the light passing hole 230 is changed too small, the distance between the optical device 300 and the inner surface of the light passing hole 230 is not significantly increased. In view of this, in the cross section where the axis of the light-passing hole 230 is located, a connection line between two ends of the light-passing hole 230 (i.e., between the first end and the second end of the light-passing hole 230) is a first connection line, and an included angle between the first connection line and the direction perpendicular to the axis is 25 ° to 45 °, so that the cross-sectional area of the light-passing hole 230 changes moderately, thereby not only ensuring the structural strength of the frame 210, but also effectively increasing the distance between the optical device 300 and the inner surface of the light-passing hole 230.
Similarly, in the cross section where the axis of the light passing hole 230 is located, the connection line between the two ends of the through hole 221 is a second connection line, and the included angle between the second connection line and the direction perpendicular to the axis is 25 ° to 45 °, so that the structural strength of the light guide plate 220 is ensured, and the distance between the optical device 300 and the inner surface of the light passing hole 230 is increased more effectively.
In a further embodiment, the backlight module 200 may further include a light shielding portion 240, the light shielding portion 240 is disposed at a seam between the frame 210 and the display module 100, that is, the light shielding portion 240 is disposed at a second end of the light through hole 230, which can be attached to the display module 100, and the light shielding portion 240 surrounds an axis of the light through hole 230. The light shielding portion 240 has a light shielding function, so as to effectively shield light emitted from the light source of the backlight module 200 from being transmitted into the optical device 300, thereby preventing the light from interfering with the optical device 300. Also, the light shielding portion 240 is disposed in a ring-shaped configuration, which can further optimize the light shielding effect thereof, so that the optical device 300 can operate more reliably. Alternatively, the light shielding portion 240 may be a light shielding glue.
In an alternative embodiment, the outer surface of the optical device 300 may be provided with a protection part 330, the protection part 330 protrudes with respect to the outer surface, and the protection part 330 faces the inner surface of the light passing hole 230. After the protection part 330 is added, the thickness of the part of the inner surface of the optical device 300 facing the light through hole 230 is increased, so that the capacity of bearing the acting force of the part is improved, even if the area of the backlight module 200 provided with the light through hole 230 collides with the optical device 300, the protection part 330 can better bear the impact force, so that the optical device 300 is less prone to damage due to the collision, and the service life of the optical device 300 is prolonged. Optionally, the protection part 330 may be configured as a ring structure, and the thickness thereof may be set to 0.1-0.5 mm, so that the space occupied by the optical device 300 is as small as possible. Alternatively, the protection part 330 may be integrally formed with other parts (e.g., the camera body 320) of the optical device 300, or may be separately disposed and then fixed together.
The electronic device disclosed by the embodiment of the invention can be a smart phone, a tablet computer, an electronic book reader or a wearable device. Of course, the electronic device may also be other devices, and the embodiment of the present invention is not limited thereto.
In the above embodiments of the present invention, the difference between the embodiments is mainly described, and different optimization features between the embodiments can be combined to form a better embodiment as long as they are not contradictory, and further description is omitted here in view of brevity of the text.
The above description is only an example of the present invention, and is not intended to limit the present invention. Various modifications and alterations to this invention will become apparent to those skilled in the art.
