Embodiment Construction

[0029] By providing a control method and an electronic device, the present application solves the technical problem in the prior art that the light-emitting device is turned on unnecessarily due to false detection, resulting in waste of electricity.

[0030] The technical solution of the embodiment of the present application is to solve the above-mentioned technical problem that the lighting device is turned on unnecessarily due to erroneous detection, resulting in a waste of electricity. The general idea is as follows:

[0031] When the light-emitting device is in the off state, the ambient light brightness value is first detected by the light sensor, and when the brightness value is less than a preset value, another sensor is turned on to detect a preset distance range near the electronic device Whether there is an obstacle inside, when an obstacle is detected, the light emitting device is controlled to keep the off state.

[0032] In order to better understand the above-men...

Abstract

The invention discloses a control method and an electronic device. The control method is applied to the electronic device. The electronic device comprises a data interface, and a light-emitting device is arranged at a position, close to the data interface, of the electronic device. The method comprises the steps that when the light-emitting device is in an off state, whether the brightness value of the environment where the electronic device is located is smaller than a preset brightness value or not is detected, when it is detected that the brightness value of the environment is smaller than the preset brightness value, a first sensing detection unit is triggered to be turned on, and whether an obstacle exists within a preset distance range is detected; when an obstacle is detected within the preset distance range, the light-emitting device is controlled to be in the off state.

Description

technical field [0001] The invention relates to the field of electronic technology, in particular to a control method and an electronic device. Background technique [0002] With the continuous development of science and technology, electronic equipment has also developed rapidly, and there are more and more types of electronic products. People have also enjoyed various conveniences brought by scientific development. Now people can use various types of electronic equipment , Enjoy the comfortable life brought by the development of science and technology. The types of existing electronic devices are becoming more and more complete, and the functions are becoming more and more perfect. For example, a smart phone can sense that when the user's face is close to the display screen, the display screen will be locked to avoid accidental touch; Intensity, automatically adjust the brightness of the display unit and so on. [0003] In the prior art, when in dark conditions, the user...
