3D holographic air dynamic projection device

Technical Field

The utility model relates to the technical field of projection, in particular to a 3D holographic air dynamic projection device.

Background

The 3D holographic air dynamic projection mainly adopts a DLP Link technology of TI, and the principle is that a DMD chip outputs a picture with a refresh rate of 120Hz, and left eyes and right eyes are alternately used, so that the eyes form an 'illusion' of 3D. The existing tools for students to learn are many, such as mobile phones and computers, especially students to train, coact, learn, show and the like outside class, the mobile phones and the computers obviously cannot meet the use requirements, and the school training cost is high, common families cannot bear the tools, so that the students can learn in a projection mode, the application of the existing projection equipment is wider and wider, in the process of not using the projection equipment at ordinary times, the lens of the projector is exposed in the air, the projection effect of the projector is affected, the heat dissipation effect is poor, and the service life is affected.
