① The operational principle of rear projection hard screens involves positioning the projection display behind the screen, with the anti-reflection layer facing the audience. By controlling the optical path, a clear and realistic image is projected into the viewer’s visible area.

② Optical characteristics of rear projection hard screens

A key feature of these rear projection hard screens is their high contrast. The light-blocking layer is distributed with translucent black particles that enhance the visual contrast of the projected images. The matte and anti-glare surface of the screen effectively absorbs reflections from surrounding light.

③ Technical advantages of rear projection displays

Completely overcoming the sun effect, these scatter screens offer an ideal display solution for brightly-lit environments. Rear projection screens exhibit four distinct advantages over traditional front projection screens:

●High contrast and bright colors

●Display bright and vibrant images in high-luminance environments

●Avoid harsh projection light on presenters

●Projection equipment is concealed behind the screen, significantly reducing noise and creating a neat environment.

④ Technical advantages of hard screen

Hard screens are made with unsaturated resin as the base material. They are rollable for easy transportation and installation, and due to their high flexibility, the arc images do not deform. In contrast, long-term use of soft screens leads to elongation due to tension, resulting in localized sagging. Consequently, their lifespan is significantly shorter than that of hard screens.
