ABSTRACT:
The present invention is a broadband projection-receiving surface that can function as a projection screen. This surface can, even in strong ambient light, provide high gain, prevent glare and speckle, provide high contrast, preserve of gray-scale linearity, provide a uniformity of brightness, provide rapid angular cut-off, preserve polarization, and provide the ability to function over a large spectral range. These achievements result from a production method that utilizes purposeful partitioning of the material processes used in sub-wavelength morphology (finish) from the processes used to make super-wavelength morphology (figure).
