Description

technical field [0001] The invention relates to the technical field of projection display, in particular to a projection device. Background technique [0002] With the rapid development of semiconductor display technology, various portable electronic devices are continuously designed and manufactured. The widespread use of portable electronic devices has pushed the user's requirements for display devices to develop in the direction of miniature, high resolution, and mobility. Driven by these strong demands, projection technology has developed rapidly, and many portable projectors with small size and high performance have appeared on the market. At present, dynamic projection is required in various application scenarios, such as a home or a large stage. The projection device needs to perform multi-directional projection according to user instructions, and needs to be synchronized with the projected content to create an immersive experience through the combination of motion a...
