Embodiment Construction

[0027] The following panel will clearly and completely describe the technical solutions in the embodiments with reference to the drawings in some embodiments.

[0028] figure 1 A schematic diagram showing a device structure of a proximity sensing function in the prior art, including a display panel 10, a rear casing 20, and a emitting device 31 to emit detection light, which is emitted through a light guide column 33 and a first window 34 on the display panel 10. When there is When the object 40 approaches the device, it will form reflected light and enter the photosensitive device 32 through the second window 35 on the display panel 10. When the photosensitive device 32 receives the reflected light, it will send a sensing signal to the processor of the device. The sensing signal determines that there is an object approaching, and calls the preset command to execute the corresponding action to make the corresponding object approach.

Abstract

An electronic device for detecting the proximity of an object and a detection method thereof, wherein the optical path direction of probe light is adjusted by a first light guide bar (303) and a first optical path adjustment layer (304) with the use of an emission device (31) and a photosensitive device (32), so that the probe light can be emitted from a first panel (100) and a second panel (200) respectively; and the optical path direction of reflected light is adjusted by the first light guide bar (303) and the first optical path adjustment layer (304), so that reflected light reflected by an object approaching the first panel (100) and an object proximate to the second panel (200) can be received, thereby both the front and back sides of the electronic device can realise the function of proximity sensing. While the electronic device realises the function of two-sided proximity sensing by means of the same set of optical proximity devices, the cost and the area of the panel can be saved and the complexity of the internal layout within the device is reduced.

Description

technical field [0001] The invention relates to the field of electronic technology, in particular to an electronic device and method for detecting the approach of an object. Background technique [0002] Today's smartphones have a proximity sensing function. By emitting infrared light, the proximity sensor is reflected by an approaching object to sense the energy of infrared light, thereby realizing the proximity sensing function. [0003] The existing technology can only realize the proximity function on a single panel of the mobile phone, and cannot detect the approach of objects on the back panel, and the proximity sensing function is limited. Contents of the invention [0004] The electronic device provided by some embodiments of the present invention is used to eliminate the problem in the prior art that the proximity sensing function is limited due to a single-panel approach. [0005] According to some embodiments in one aspect, an electronic device for detecting th...
