Detailed Description

Reference will now be made in detail to embodiments of the present application, examples of which are illustrated in the accompanying drawings, wherein like or similar reference numerals refer to the same or similar elements or elements having the same or similar function throughout. The embodiments described below with reference to the accompanying drawings are illustrative and are only for the purpose of explaining the present application and are not to be construed as limiting the present application.

Referring to fig. 1-2, an electronic device 100 according to an embodiment of the present disclosure includes a display 10, a cover 20, a light sensor 30, and a light function 40. The cover plate 20 covers the display screen 10. The light sensor 30 is disposed on a side corresponding to the side of the display screen 10. The light function 40 is disposed between the light sensor 30 and the cover plate 20. The optical function member 40 is used for absorbing the reflected light emitted from the display screen 10 and reflected to the light sensor 30, and for making the light sensor 30 sense the target light through the optical function member 40 and the cover plate 20.

In the electronic device 100 of the embodiment of the application, since the optical function component 40 can absorb the reflected light and enable the optical sensor 30 to sense the target light, the interference of the light emitted from the display screen 10 to the optical sensor 30 can be avoided, and thus the accuracy of sensing the target light by the optical sensor 30 is improved.

In addition, the light sensor 30 is disposed at a side corresponding to the side of the display screen 10, so that light emitted from the display screen 10 can be prevented from directly entering the light sensor 30, information of target light can be prevented from being finally obtained by calculating according to the optical signal sensed by the light sensor 30 and the optical signal of the display screen 10, the calculation amount of the electronic device 100 is reduced, the display screen 10 is prevented from being stuck, and power consumption of the electronic device 100 can be reduced.

Specifically, the electronic apparatus 100 may be any of various types of computer system devices (an example in fig. 1 is a cellular phone) that is mobile or portable and performs wireless communication. Specifically, the electronic apparatus 100 may be a mobile phone, a portable game device, a laptop, a portable internet device, and the like, and the electronic apparatus 100 may also be a wearable device, such as a smart watch or a head-mounted device.

The display screen 10 is for example an OLED display screen. The Organic Light-Emitting Diode (OLED) display 10 is Light, thin and bendable. Therefore, the OLED display screen can also satisfy the curved surface modeling of the electronic device 100 when exhibiting the content effect. The display screen 10 can also adopt a Micro LED display screen or a liquid crystal display screen. Of course, these display screens 10 are merely exemplary, and embodiments of the present application are not limited thereto.

The material of the cover plate 20 may be made of a light-transmitting material such as glass, ceramic, or sapphire. Since the cover plate 20 covers the display screen 10, in order to protect the display screen 10, the cover plate 20 may be made of a material with a relatively high hardness, such as a sapphire material, or a hardened layer may be formed on the surface of the cover plate 20 to improve the scratch resistance of the cover plate 20.

The light sensor 30 is, for example, an ambient light sensor, and it can be understood that the ambient light sensor can sense the brightness of the ambient light, and the electronic device 100 can adjust the brightness of the display screen 10 according to the brightness of the ambient light. Of course, the light sensor 30 may also be a receiver of a proximity sensor, and the receiver of the proximity sensor may receive the light reflected by the target object, so that the electronic device 100 can determine the distance between the target object and the electronic device 100.

As shown in fig. 1 and fig. 3, the light sensor 30 is located on the top of the electronic device 100, but in other embodiments, the light sensor 30 may be located on the bottom or the side of the electronic device 100. It should be noted that, here, the "top" of the electronic device 100 refers to the end of the electronic device 100 facing the front of the user in the state of normal use of the electronic device 100 by the user.

In the embodiment of the present application, the light sensor 30 is covered by the cover plate 20, or the light sensor 30 is disposed below the cover plate 20. The light sensor 30 is disposed under the cover plate 20, which means that the light sensor 30 is disposed under the cover plate 20, and the projection of the light sensor 30 on the plane of the cover plate 20 is located in the cover plate 20.

The light function 40 may be made of a black material so that the light function 40 may absorb light reaching the light function 40. The material used for the optical function member 40 is, for example, foam, Polyethylene terephthalate (PET), or the like. The light function has a light-transmitting structure, so that the target light of a specific angle range can pass through the light function 40 from the light-transmitting structure to be sensed by the light sensor 30.

Referring to fig. 4, in some embodiments, the light function member 40 may include a light absorbing portion 41 and a plurality of light transmitting portions 42 formed in the light absorbing portion 41, the light absorbing portion 41 being used for absorbing the reflected light, and the light transmitting portions 42 being used for allowing the light sensor 30 to sense the target light through the cover plate 20 and the light transmitting portions 42.

Thus, the light absorbing portion 41 can prevent the reflected light emitted from the display screen 10 from interfering with the light sensor 30, and the light transmitting portion 42 can enable the light sensor 30 to normally sense the target light.

Specifically, the light absorbing portion 41 may be made of the black material such as the foam described above. The light-transmitting portion 42 may be solid or virtual. In one example, the light transmitting portion 42 is a light transmitting hole 421, and the light transmitting hole 421 penetrates the light absorbing portion 41. It is understood that the environment can be received by the light sensor 30 after passing through the cover plate 20 and the light passing hole 421 in sequence. The cross-sectional shape of the light passing hole 421 may be circular, square, or the like. In the example of fig. 4, the cross-sectional shape of the light passing hole 421 is a rectangle. In the example of fig. 5, the cross-sectional shape of the light passing hole 421 is circular.

Further, the depth direction of the light passing hole 421 may coincide with the thickness direction of the cover plate 20. This makes it easier for the object light perpendicular to the cover plate 20 to pass through the light passing hole 421 and be sensed by the light sensor 30. Of course, in some embodiments, the depth direction of the light passing hole 421 may form a certain angle with the thickness direction of the cover plate 20 as long as the light function member 40 can absorb the reflected light and the target light can pass through.

Note that, in the case where the light-transmitting portion 42 is a solid body, the light-transmitting portion 42 may be made of a light-transmitting material, and for example, the light-transmitting portion 42 may be formed of a light-transmitting resin.

Referring to fig. 2 again, in some embodiments, the electronic device 100 includes an optical adhesive 50 disposed between the cover plate 20 and the display screen 10, and the light functional element 40 is used for absorbing the reflected light reflected by the optical adhesive 50 and the cover plate 20 to the light sensor 30. It is understood that the optical glue 50 and the cover plate 20 both have light transmittance, and light rays emitted from the display screen 10 at a specific angle can be totally reflected in the optical glue 50 and the cover plate 20 after entering the optical glue 50 and the cover plate 20, and these reflected light rays can be emitted out of the optical glue 50 and the cover plate 20 to the light sensor 30 again. Therefore, the optical function 40 absorbs the reflected light, so that the interference of the reflected light with the target light sensed by the sensor 30 can be reduced. As discussed above, light reflected by the optical glue 50 and the cover plate 20 may be absorbed by the light absorbing portion 41 of the light function 40.

As shown in fig. 2, the light beam forming total reflection in the cover plate 20 is L1, the light beam forming total reflection in the optical glue 50 is L2, and both the light beam L1 and the light beam L2 reaching the optical function 40 are absorbed by the optical function 40.

Referring to fig. 2, in an example, the optical adhesive 50 and the optical functional element 40 are attached to the lower surface of the cover plate 20 and are arranged in parallel, and the thickness of the optical functional element 40 is greater than or equal to the thickness of the optical adhesive 50. Generally, the light entering the optical cement 50 and forming the total reflection in the optical cement 50 is finally emitted from the side of the optical cement 50, and the emitted light may reach the light sensor 30 to interfere with the normal operation of the light sensor 30. Therefore, the optical glue 50 and the optical function member 40 are arranged in parallel, and the thickness of the optical function member 40 is greater than that of the optical glue 50, so that the optical function member 40 can absorb the light emitted from the side surface of the optical glue 50, and the interference of the light to the light sensor 30 is reduced, thereby improving the accuracy of the light sensor 30 for sensing the target light.

The optical function member 40 may be fixed to the lower surface of the cover plate 20 by adhesive bonding. Of course, in other embodiments, the optical function 40 may be fixed in position in other ways, for example, the optical function 40 may be fixedly connected to the side of the optical glue 50.

Further, in some embodiments, the electronic device 100 may include a polarizer 60 disposed between the display screen 10 and the optical glue 50, as shown in fig. 2. The optical glue 50 adheres the cover plate 20 and the polarizer 60. The polarizer 60 may prevent some light rays with specific phases in the target light rays from entering the display screen 10, so as to reduce interference of the target light rays on the light rays emitted from the display screen 10, thereby enabling a user to more clearly see contents displayed by the display screen 10.

In the embodiment of the present application, the cover plate 20, the optical cement 50, the polarizer 60, and the display screen 10 are stacked from top to bottom. The light emitted from the display screen 10 sequentially passes through the polarizer 60, the optical adhesive 50 and the cover plate 20 and then exits to the outside of the electronic device 100.

Referring to fig. 2, in some embodiments, the electronic device 100 may further include an ink layer 70 coated on the lower surface of the cover plate 20, wherein the ink layer 70 surrounds the optical functional element 40. The ink layer 70 may cover the content structure of the electronic device 100, so that the electronic device 100 is more beautiful. The ink layer 70 may be black or white.

Note that the ink layer 70 is formed with a through hole 71 corresponding to the light sensor 30, and the optical function member 40 is disposed at the through hole 71. The through-hole 71 may allow the object light to pass through the cover plate 20.

In some embodiments, the light function 40 at least partially shades the light sensor 30 along the thickness direction of the cover plate 20. That is, the optical function 40 may partially shield the light sensor 30, as shown in fig. 6 and 7; the light function 40 may also completely shade the light sensor 30, as shown in fig. 3. The light function 40 completely shields the light sensor 30 means that in the orthographic projection of the light sensor 30 and the light function 40 on the lower surface of the cover plate 20, the projection of the light sensor 30 is located in the projection of the light function 40.

When the light function 40 partially shields the light sensor 30, the light function 40 can make more target light reach the light sensor 30 to be sensed by the light sensor 30. At this point, it is only necessary to ensure that the light function 40 can absorb the reflected light.

Referring to fig. 2, in some embodiments, the electronic device 100 includes a housing 80, the housing 80 includes a bottom wall 81 and a side wall 82 extending from the bottom wall 81, the display screen 10 and the light sensor 30 are disposed on the bottom wall 81, and the cover plate 20 is disposed on the side wall 82.

Thus, the housing 80 can reduce the impact on the components such as the cover plate 20, and improve the service life of the electronic device 100. Specifically, the housing 80 is a substantially rectangular frame, so that the electronic device 100 formed by assembling the housing 80 and the cover plate 20 is rectangular. In order to make the electronic device 100 beautiful, the corner positions of the housing 80 may be rounded to make the electronic device 100 have a rounded rectangular shape. The housing 80 may be formed by machining an aluminum alloy using a numerical control machine, or may be formed by injection molding of a material such as Polycarbonate (PC).

In one embodiment, the bottom wall 81 and the side wall 82 may be integrally formed, for example, the bottom wall 81 and the side wall 82 may be formed by injection molding. Of course, the bottom wall 81 and the side wall 82 may be formed as separate bodies, for example, after the bottom wall 81 and the side wall 82 are formed as separate bodies, the bottom wall 81 and the side wall 82 are connected together by welding, bonding, or screwing.

The light sensor 30 may be connected to the motherboard of the electronic device 100 through a flexible circuit board, so that the battery of the electronic device 100 may supply power to the proximity sensor through the motherboard.

Further, the bottom wall 81 may be formed with a receiving groove 811, and the light sensor 30 is at least partially received in the receiving groove 811. Alternatively, the light sensor 30 may be partially or completely received in the receiving groove 811, such that the light sensor 30 and the housing 80 are more compactly engaged, and the electronic device 100 may be more miniaturized.

Specifically, the shape of the receiving cavity 811 may be similar to the shape of the optical sensor 30, for example, the receiving cavity 811 and the optical sensor 30 may be square, so that the optical sensor 30 and the receiving cavity 811 may be more compactly engaged. It is understood that the size of the receiving groove 811 is slightly larger than the size of the optical sensor 30, so that the optical sensor 30 can be placed in the receiving groove 811.

Of course, in some embodiments, the receiving groove 811 may be omitted, as shown in fig. 8.

Referring to fig. 2, in some embodiments, a buffer layer 90 is disposed between the display screen 10 and the bottom wall 81, and the display screen 10 is supported on the bottom wall 81 by the buffer layer 90. The buffer layer 90 is, for example, foam, and the buffer layer 90 can reduce the impact between the display screen 10 and the bottom wall 81, so as to prevent the display screen 10 from being damaged, thereby improving the service life of the display screen 10.
