ABSTRACT:
An optica image forming screen which comprises a multiplicity of light-transmitting elements in a matrix of light-absorbing elements so that light incident upon the elements at an angle greater than a predetermined angle will be internally absorbed by the elements, with no significant reflection internal to the elements and with element size conducive to a scattering effect by using diffraction in the image space.
