Abstract

An embodiment of the present invention provides an electronic device and a projection display method using the electronic device, the electronic device includes a light source and a lens, wherein the light source includes at least one visible light source and at least one infrared light source , the at least one visible light source is used to emit visible light, and the at least one infrared light source is used to emit infrared light; the lens is used to project the mixed visible light and the infrared light emitted by the infrared light source to project and display the first projected image in the projected area; wherein, the projected area corresponding to each pixel of the first projected image is incident by visible light and infrared light. Since the projection area corresponding to each pixel of the projection image transmitted by the electronic device provided by the present invention has visible light and infrared light incident, it is convenient to determine the position of the projection area through the infrared light reflected in the projection area, and then accurately perform Gesture Recognition.

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 ...
