ABSTRACT:
The invention provides an improved projector screen structure. The improved screen structure is constituted by twist yarns from superfine single yarns and superfine nickel (Ni) chromium (Cr) alloy fiber. Through up-and-down weaving method for plain woven texture, all yarns are arranged in an organized and uniform fashion with tight spacing, so the fine screen constituted by such structure is suitable for any projectors that have different screen requirements and may be used to both front and back projection. The screen produced in this way can also deliver wide view angle, increased color saturation and contrast as well as better layer and three-dimensional effect. Moreover, the screen has zero radiation, low reflection, uniform light absorbance, flatness, antibacterial property, dustproof effect, water cleanability and durability, which are excellent attributes that traditional screens do not have. The present screen further improves comfort level for audiences and meets environmental requirements after disposal.
