Abstract

The embodiment of the invention provides electronic equipment and a method for carrying out projection display by utilizing the electronic equipment. The electronic equipment comprises a luminous source and a lens, wherein the luminous source comprises at least one visible light luminous source and at least one infrared luminous source; the visible light luminous source is used for emitting visible light; the infrared luminous source is used for emitting infrared light; and the lens is used for projecting out the visible light subjected to blending color mixing processing and the infrared light emitted by the infrared luminous source, so that a first projection image is protected and displayed in a projection region, wherein the visible light and the infrared light are respectively emitted into projection regions corresponding to each pixel of the first projection image. The visible light and the infrared light are respectively emitted into the projection regions corresponding to each pixel of the projection image transmitted by the electronic equipment provided by the invention, so the position of the projection region can be conveniently determined through infrared light rays reflected in the projection region, and the gesture recognition is accurately carried out.

Description

technical field [0001] The invention relates to the field of electronic equipment, in particular to an electronic equipment and a projection display method. Background technique [0002] The current mobile terminal has integrated a projection module and has a projection function. The projection module of the mobile terminal can be used to project the content displayed on the terminal on a plane, such as a wall or a desktop, so that the user can obtain a larger image display. The mobile terminal in the prior art can only realize the function of projecting the content displayed on the terminal onto the plane, and the operations on the displayed content are all performed on the screen of the terminal, so that the user's line of sight needs to switch repeatedly between the terminal screen and the projection plane , which is not convenient for users to apply. In the prior art, there is no method and device that enables the user to operate the projected content on the projected ...
