Embodiment Construction

[0083] Reference will now be made in detail to the exemplary embodiments, examples of which are illustrated in the accompanying drawings. When the following description refers to the accompanying drawings, the same numerals in different drawings refer to the same or similar elements unless otherwise indicated. The implementations described in the following exemplary examples do not represent all implementations consistent with the present disclosure. Rather, they are merely examples of apparatuses and methods consistent with aspects of the present disclosure as recited in the appended claims.

[0084] Full screen has gradually become the trend of mobile terminal design. The difficulty in realizing the full screen lies in how to cancel or hide the front camera, distance sensor, microphone, etc. on the front of the mobile terminal. In order to realize a full screen, the above-mentioned front camera, distance sensor, earpiece, etc. must be placed under the screen of the mobile ...

Abstract

The invention relates to a distance sensor module, a mobile terminal, a distance detection method and device and a storage medium. The distance sensor module is arranged below a screen of the mobile terminal. The distance sensor module comprises a light emitter, a light receiver, an analog front end, an analog-digital converter and a micro-control unit. The method comprises the steps of: controlling the light receiver to generate a light signal after receiving reflected detection light emitted by the light emitter, wherein the detection light is detection light with the wavelength larger than1,300 nm; controlling the optical receiver to convert the optical signal into a first current signal; executing processing conversion on the first current signal to obtain a digital signal; and controlling the micro-control unit to detect the distance according to the digital signal. Because the wavelength of the detection light is increased and the frequency is reduced, the photon energy in the detection light is low, and the problem that the detection light is excited in the mobile terminal screen to generate bright spots is further solved.

Description

technical field [0001] Embodiments of the present disclosure relate to the technical field of terminals, and in particular, to a distance sensor module, a mobile terminal, a distance detection method, device, and storage medium. Background technique [0002] The mobile terminal is usually equipped with a distance sensor module for detecting the distance between the screen of the mobile terminal and the obstacle ahead. [0003] In the related art, in order to increase the screen-to-body ratio of the mobile terminal, it is necessary to arrange the distance sensor module under the screen of the mobile terminal. The distance sensor module includes a light transmitter and a light receiver. Light emitters emit light, such as lasers or infrared light, outwards. [0004] However, when the light emitter arranged under the screen of the mobile terminal emits light, bright spots will be excited on the screen of the mobile terminal, which will affect the display effect of the screen o...
