Detailed Description

Reference will now be made in detail to embodiments of the present invention, examples of which are illustrated in the accompanying drawings, wherein like 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 only for the purpose of explaining the present invention, and are not to be construed as limiting the present invention.

Electronic devices, such as mobile phones or tablet computers, generally detect a distance between the electronic device and a user by installing a proximity sensor and a light sensor and adjust screen brightness according to surrounding environments. Taking a mobile phone as an example, a proximity sensor is provided in an upper region of the mobile phone. When a user carries out voice call or related operation, the mobile phone is close to the head, the proximity sensor feeds distance information back to the processor, and the processor executes corresponding instructions, such as closing light of the display screen assembly. The light sensor is also arranged in the upper area of the mobile phone, and is used for feeding back the light intensity of the environment to the processor when a user is under the sun or in a dark environment, and the processor executes corresponding instructions, such as increasing or reducing the light brightness of the display screen assembly.

In the related art, a proximity sensor or an optical sensor arranged on an electronic device needs to be provided with a corresponding hole on a housing for transmitting and receiving an optical signal, but with the rapid development of the electronic device, people have higher and higher requirements on the appearance and the operation experience of a mobile phone. The mobile phone is developed towards a full-screen mobile phone, and the full-screen mobile phone forms an ultra-narrow frame between a shell and a display screen assembly, and due to the fact that the width of the ultra-narrow frame is too small, the ultra-narrow frame may not have enough space for forming holes, and the strength of the whole frame is reduced even if the holes are formed.

Referring to fig. 1 to fig. 3, an electronic device 100 according to an embodiment of the invention may be a mobile phone or a tablet computer. The electronic device 100 according to the embodiment of the present invention is described by taking a mobile phone as an example, but it is to be understood that the specific form of the electronic device 100 may be other, and is not limited herein.

The electronic device 100 includes a receiver 12, a cover 11, and a function 14. The cover plate 11 is provided with a through hole 111 corresponding to the receiver 12, the functional element 14 covers the receiver 12, and the functional element 14 is used for preventing dust of the receiver 12 and receiving visible light or infrared light through the through hole 111.

The functional element 14 can be used for both receiving visible and infrared light and for dust protection of the receiver 12, while the electronic device 100 further comprises an infrared light emitter 16, and the cooperation of the functional element 14 and the infrared light emitter 16 can replace the functions of a proximity sensor and a light sensor for distance detection and ambient light detection. When distance detection is performed, for example, when a user is answering or making a call, the electronic device 100 is close to the head, the infrared light emitter 16 emits infrared light, when the emitted infrared light meets an obstacle in a detection direction, a part of the infrared light is reflected back to be received by the functional part 14, because the functional part 14 is a photoelectric conversion device made by using a semiconductor photovoltaic effect, when the infrared light irradiates on the diode 142 of the functional part 14, an electromotive force is formed at two ends of a PN junction in the diode 142 to generate a current, and the processor calculates the time from the infrared light emitter 16 emitting the infrared light to the PN junction in the diode 142 to generate the current, so that the distance between the electronic device 100 and the obstacle can be determined and corresponding adjustment can be made, for example, a corresponding instruction is sent to turn off a screen light. When the electronic device 100 is far away from the head, the processor calculates again according to the feedback data and sends an instruction to turn on the screen light again. Therefore, misoperation of a user can be prevented, and the electric quantity of the mobile phone can be saved.

When the ambient light detection is performed, for example, when the user is under the sun, the ambient light is strong, and the visible light irradiates on the diode 142 of the function element 14, the current generated at the PN junction in the diode 142 is large, the function element 14 feeds back the magnitude of the generated current to the processor, and the processor executes a corresponding instruction, such as enhancing the brightness of the display screen to adapt to the light intensity of the current environment, so that the content of the screen viewed by the user is clearer. When the user is in a dark environment, the ambient light is weak, the current generated by the visible light irradiating the PN junction is small, the functional part 14 feeds the current back to the processor again, and the processor executes corresponding instructions such as reducing the brightness of the display screen to adapt to the light intensity of the current environment, so that the user does not feel dazzling when watching the screen content, the eyesight of the user can be protected, the electric quantity of the mobile phone can be saved, and the effect of prolonging the service life of the battery can be further achieved. In actual operation, the function 14 receives infrared light and visible light in a time-sharing manner, for example, performs distance detection when performing a relevant operation such as answering a call, and performs ambient light detection when performing an operation such as browsing display contents.

The housing 20 is used to house components and assemblies for protection. By providing the housing 20 to enclose the components and assemblies within the electronic device 100, direct damage to these components from external factors is avoided. The housing 20 may be formed by CNC machining of an aluminum alloy, or may be injection molded using Polycarbonate (PC) or PC + ABS material.

As described above, the functional element 14 of the electronic device 100 according to the embodiment of the present invention can be used for both receiving visible light and infrared light and preventing dust of the receiver 12, and can perform distance detection and ambient light detection by using the functions of the proximity sensor and the optical sensor that can be replaced by the infrared light emitter 16, thereby eliminating the need to mount the proximity sensor element and the optical sensor element on the electronic device 100, reducing the position occupied above the screen, and improving the screen occupation ratio of the electronic device 100.

Referring to fig. 3, in some embodiments, the functional element 14 includes a substrate 141, and a diode 142 is disposed on the substrate 141 to receive visible light or infrared light.

Specifically, receiver 12 is used to output sound, and dust particles attached to receiver 12 may degrade performance of receiver 12, resulting in poor output sound effect and poor user experience. In order to maintain the stability of the operation performance of receiver 12 and to prolong the life of receiver 12, a dust-proof net is formed by opening a mesh on substrate 141 covering receiver 12, and the mesh can be formed on substrate 141 by photolithography or chemical etching.

The display screen 13 may also be a Micro LED display screen. Of course, these display screens are merely exemplary and embodiments of the present invention are not limited in this respect.

Referring to fig. 6, in some embodiments, the electronic device 100 further includes a cover buffer layer 18, and the buffer layer 18 is disposed below the display 13.
