An ambient light sensor configured in an electronic device can sense the external ambient light intensity, so the display brightness of the electronic device can be adjusted. Moreover, when the quantity of the ambient light sensors configured in the electronic device increases, the detection range of an ambient light field can be greatly increased to reflect the ambient light situation around a mobile phone more truly. How to increase the quantity of the ambient light sensors and optimize the layout space of the electronic device simultaneously has become a technical problem to be solved.
The disclosure relates to the technical field of terminals, and to an electronic device, to solve deficiencies in the related art.
According to an example of the disclosure, an electronic device is provided and includes: a shell; a display panel, the display panel or the shell including a light-transmitting area; an ambient light sensor; an infrared transmitter; and a light guiding piece including a light incident end and a light emitting end. The light incident end is arranged facing the light-transmitting area, and the light emitting end is arranged facing the ambient light sensor and the infrared transmitter.
The drawings herein are incorporated into the specification and constitute a part of the specification, which show examples consistent with the disclosure, and are used together with the specification to explain the principle of the disclosure.
Examples will be described in detail herein, implementations of which are illustrated in the accompanying drawings. When the following description refers to the accompanying drawings, the same numbers in different drawings represent the same or similar elements unless otherwise indicated. The implementation examples described in the following examples do not represent all implementation examples consistent with the disclosure. On the contrary, they are merely examples of an apparatus or a method consistent with some aspects of the disclosure as detailed.
The terms used in the disclosure are only for the purpose of describing specific examples, and are not intended to limit the disclosure. The singular forms of “a”, “an”, and “the” used in the disclosure are also intended to include plural forms, unless the context clearly indicates other meanings.
It should be understood that although the terms “first”, “second”, etc. may be used in the disclosure to describe various information, the information should not be limited to these terms. These terms are only used to distinguish the same type of information from each other. For example, without departing from the scope of the disclosure, the first information may also be referred to as second information, and similarly, the second information may also be referred to as first information.
The light guiding piece 5 may include a light incident end 51 and a light emitting end 52. The light incident end 51 is configured facing the light-transmitting area 21 of the display panel 2, and the light emitting end 52 may be configured facing the ambient light sensor 3 and the infrared transmitter 4, so that the external ambient light can be transmitted to the ambient light sensor through the light-transmitting area 21 and the light guiding piece 5, while the infrared light emitted by the infrared transmitter 4 can also be emitted to the outside of the electronic device 100 through the light guiding piece 5 and the light-transmitting area 21. Based on this, the ambient light and the infrared light can be transmitted simultaneously through the light guiding piece 5. The ambient light sensor 3 and the infrared transmitter 4 can share the same light guiding piece 5, which is conducive to increasing the quantity of the ambient light sensors 3 for the electronic device 100, so as to improve the detection accuracy of the ambient light intensity, and further save the internal space of the electronic device.
The above description takes the display panel 2 including the light-transmitting area 21 as an example. In fact, in other examples, the light-transmitting area may also be formed on the shell 1, for example, an opening may be processed and formed in the shell 1 as the light-transmitting area, or an opening may be formed in a top of the shell 1 as the light-transmitting area. Compared with the solution of forming the light-transmitting area 21 on the display panel 2, the display area of the display panel 2 does not need to be occupied in the solution where the light-transmitting area is formed on the shell 1, and the light-transmitting area need not be arranged on a display side of the electronic device 100, which can improve the visual effect. And, when the light-transmitting area is located at the top of the electronic device 100, it is conducive to increasing the light field range of the ambient light sensor 3 and greatly improving the detection accuracy.
In the example, the ambient light sensor 3 and the infrared transmitter 4 can guide light through different light guiding channels of the light guiding piece 5 respectively. In one example, as still shown in
Further, the light guiding piece 5 may further include a light guiding seat body 56, which is respectively connected with the first light guiding column 53, the second light guiding column 54 and the light-shielding body 55. The light guiding seat body 56 may further be connected with the shell 1 of the electronic device 100, so as to fix the light guiding piece 5 into the electronic device 100 and avoid moving. The ambient light sensor 3 and the infrared transmitter 4 may be connected to an end, facing away from the first light guiding column 53 and the second light guiding column 54 of the light guiding seat body 56, so as to achieve the purpose of light guidance through the first light guiding column 53 and the second light guiding column 54. The first light guiding column 53, the second light guiding column 54 and the light guiding seat body 56 may be integrally formed, or in other cases, the first light guiding column 53, the second light guiding column 54 and the light guiding seat body 56 may also be separately formed, and their relative positions and relationship may be fixed, e.g., by bonding or other means. The light guiding seat body 56 and the light-shielding body 55 may be fixedly connected by bonding.
In the example, as shown in
In another example, as shown in
In order to achieve the physical isolation of the ambient light path and the infrared light path on the shared part 57, as shown in
The shared part 57 includes a polycarbonate light-transmitting shared part. One part, connected with the first light guiding sub-part 58 and located on a side of the light-shielding boundary layer 571 of the polycarbonate light-transmitting shared part, may transmit the ambient light; and one part, connected with the second light guiding sub-part 59 and located on a side of the light-shielding boundary layer 571 of the polycarbonate light-transmitting shared part may transmit the infrared light. The first light guiding sub-part 58 may include a visible light guiding sub-part, and the second light guiding sub-part 59 may include an infrared light guiding sub-part.
Further, as still shown in
In other cases, the ambient light sensor 3 and the infrared transmitter 4 may also share the same light guiding channel of the light guiding piece 5, so as to simplify a structure of the light guiding piece 5. For example, as shown in
In the example, when the ambient light sensor 3 and the infrared transmitter 4 have the same height, as shown in
After considering the specification and practicing the disclosure disclosed herein, those skilled in the art will easily think of other embodiments within the scope of the disclosure. The disclosure is intended to cover any variations, uses, or adaptive changes within the scope of the disclosure. These variations, uses, or adaptive changes follow the general principles of the disclosure and include common knowledge or conventional technical means in the technical field that are not disclosed in the disclosure.
It will be appreciated that the disclosure is not limited to the exact construction that has been described above and illustrated in the accompanying drawings, and that various modifications and changes can be made without departing from the scope thereof. It is intended that the scope of the disclosure only be limited by the appended claims.
