Abstract

The embodiment of the invention provides a control method and device which are applied to an electronic device. The electronic device comprises a display module and a projection module. Output contents can be displayed through the display module of the electronic device or can be projected to a projection screen through the projection module of the electronic device. The control method includes the steps of detecting the state of the projection module; when it is detected that the electronic device controls the projection module to conduct projection, obtaining first display luminance of the display module at present; controlling the display module to be switched from the first display luminance to second display luminance, wherein the second display luminance is lower than the first display luminance. By means of the control method and device, power consumption of the electronic device during projection is reduced.

Description

technical field [0001] The present application relates to the field of electronic technology, and more specifically relates to a control method and device. Background technique [0002] With the development of electronic technology, the functions realized by electronic devices are becoming more and more diversified. In order to better display display functions, electronic devices with projection modules emerge as the times require. [0003] However, the more functions the electronic equipment can realize, the greater the power consumption will be. The inventor found in the research that when the electronic equipment uses the projection module for projection, the power consumption of the electronic equipment will be further increased, which is not conducive to the development of electronic equipment. and use. Contents of the invention [0004] In view of this, the present application provides a control method and device to solve the problem of high power consumption of ele...
