Embodiment Construction
[0059] Embodiments of the present invention are described in detail below, examples of which are shown in the drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below by referring to the figures are exemplary only for explaining the present invention and should not be construed as limiting the present invention.
[0060] An electronic device, such as a mobile phone or a tablet computer, generally detects a distance between the electronic device and a user by installing an infrared sensor. Taking a mobile phone as an example, an infrared sensor is provided on the upper area of the mobile phone. When the user makes a voice call or related operations, the mobile phone is close to the head, and the infrared sensor feeds back the distance information to the processor, and the processor executes corresponding instructions, such as turning off the lights ...

Abstract
The invention discloses an optical sensor, an electronic device and a manufacturing method thereof. The light sensor includes a substrate, an emitter and a receiver, and the receiver surrounds the emitter and is also arranged on the substrate. Electronics include a light-transmitting display and a light sensor. Wherein, the light-transmitting display screen includes an upper surface and a lower surface opposite to the upper surface, the light-transmitting display screen is used for displaying light through the upper surface, and the light sensor is arranged opposite to the lower surface. The optical sensor, electronic device and manufacturing method thereof of the present invention can place the optical sensor under the light-transmitting display screen in the case of a full screen, avoiding the traditional opening operation, and ensuring the reliability of the overall strength of the frame area of the electronic device. The screen-to-body ratio of the electronic device is further improved. The integral arrangement of the transmitter and the receiver makes the overall structure of the components compact, which is beneficial to reducing the position occupied by the electronic device and improving the utilization rate of the space of the electronic device.
Description
technical field [0001] The invention relates to the field of electronic technology, in particular to an optical sensor, an electronic device and a manufacturing method thereof. Background technique [0002] In an electronic device, a proximity sensor and an ambient light sensor are usually integrated. In order to ensure the reliability of signal transmission and reception, it is usually necessary to open a large opening on the cover of the electronic device. However, the opening operation will reduce the screen-to-body ratio of the electronic device, and it is also not beautiful enough. Contents of the invention [0003] Embodiments of the present invention provide an optical sensor, an electronic device, and a manufacturing method thereof. [0004] The light sensor of the embodiment of the present invention comprises: [0005] Substrate; [0006] an emitter disposed on the substrate for emitting infrared light; and [0007] A receiver surrounding the transmitter for r...
