Basic knowledge of electric projection screen
Electric screen is currently the most widely used screen, which are relatively inexpensive, easy to use, wired and wireless remote control two control modes, the general synchronous motor or tubular motor control movements, lifting slow synchronous motor, faster than tubular motor for fast, for the curtain, the latter life or whether the results are far better than the former. Curtain material commonly used white plastic or cloth made of fiberglass cloth material. White plastic screen because of its low cost, low-end curtain in Bristol most widely used, because of its material properties of glass fiber cloth is more stiff, so often used in high-grade curtain. Flatness electric curtain curtain almost entirely dependent on the quality of the substrate, after a period of use, the screen surface as the ambient temperature and humidity changes, coupled with the lifting several times wound, prone to the screen surface on both sides of the bead, V-striped , vertical stripes and other irregularities phenomenon.
Another branch is the electric tab tension screen, its screen surface are made of flexible PVC material, and the general difference is that the bracing wire is on both sides of the screen, there will be two arcuate side cable stretched to live screen surface giving a horizontal screen surface tension, coupled with longitudinal tension rod sagging, which stretched across the flat screen surface. This screen structure, to ensure long-term use screen surface are smooth as a mirror, and more generally for the screen surface flatness demanding reflection type optical screen, because the structure and production are more complex, so the price is also more expensive. There are a number of low-cost electric cable screen is often used hard texture of matte white or fiberglass cloth as the screen surface, the side code would not achieve the basic fundamental role of stretching, only have their table it.
