VIVID Storm rising projector screen

High Qualified Electric Floor Rising 4K ALR Grey Crystal Rollable Projector Screen Motorized Pull Up 4K Ambient Light 120''150'' is our newly upgraded retractable motorized electric floor rising screen that extends upwards from the floor with black diamond ALR ambient light rejecting technology. The black diamond.8 ALR is an angular reflective material that incorporates a high-contrast diffusion layer to provide contrast-rich images in ambient light room environments to combat the washout effect typically experienced with matte white materials. The projection screen surface ascends and descends into its housing for a non-invasive solution where permanent installations are not practical. In addition, it has a variety of intelligent control methods, as well as the only anti-trap design, human-sensor lighting function and so on.
