Abstract

Disclosed is an instant-on ambient visual projection device including: a first projection assembly including a display screen, a first light source serving as backlight of the display screen, and a first optical path unit guiding content to be played to form dynamic images projected into space; a second projection assembly including a second light source, and a second optical path unit guiding light therefrom to form ripple light patterns projected into space; a third projection assembly including a third light source, and a third optical path unit guiding light therefrom to form light diffraction patterns projected into space; and a controller configured to control operations of the first, second and third light sources and the playback of the display screen, and including a storage unit for storing the content to be displayed. This allows, upon startup, minimization of user interaction and waiting time while enhancing user experience.

Dependent claims

An instant-on ambient visual projection device, comprising:

a first projection assembly, a second projection assembly, a third projection assembly and a controller;
wherein the first projection assembly comprises a display screen, a first light source and a first optical path unit, wherein the first light source serves as a backlight for the display screen, and a content displayed on the display screen, under a guidance of the first optical path unit, forms a dynamic image that is projected into space;
the second projection assembly comprises a second light source and a second optical path unit, wherein a light emitted by the second light source, under a guidance of the second optical path unit, forms a ripple light pattern that is projected into space;
the third projection assembly comprises a third light source and a third optical path unit, wherein a light emitted by the third light source, under a guidance of the third optical path unit, forms a light diffraction pattern that is projected into space;
and
the controller is configured to control operations of the first light source, the second light source and the third light source, and to control a playback of the display screen, wherein the controller comprises a storage unit for storing a content to be displayed on the display screen.
