发明名称 Flexible screen for front and rear projection
摘要 A projection screen is constructed of an open mesh fabric central portion for imaging a projected image, a sturdier border, and hanging hardware at each of the corners of the border. The central portion is constructed of a knit of multiple synthetic fibers twisted together and provides a screen with high diffusion. The open mesh provides substantial transparency to the screen when no image is being projected onto the screen permitting the screen to be used in a manner in which it will not act as a significant visual barrier when installed but not in use. The screen is mounted with hanging hardware that pulls the border and central portion taut. The screen when installed and taut has high diffusion and permits both front and rear projection with substantially equal brightness at both sides of the screen.
