Problems solved by technology

[0002] The digital cinema machine applies the digital micromirror switch device DMD—digital optical switch array and digital signal processing technology, and adopts the new digital film projection mode of the digital light processing technology DLP, which replaces the film image reproduction mode of the traditional film film projector, and realizes no film Projection, the projector needs to be protected by a protective device when it is in use, but there are some problems with the projector: 1. Because there is a protective shell on the outside of the projector, it is not convenient to debug the projector; 2. The protective shell cannot be adjusted according to the plane on which it is placed. Adjusting the angle will cause the projected picture to be incorrect; 3. The dust in the air will easily affect the picture quality during the use of the projector
