Abstract
A display system includes a display medium which comprises a display layer providing a display area capable of converting coherent light into light of a shorter wavelength through a nonlinear optical effect and converting the coherent light into scattered light. The display area is illuminated imagewise with coherent light such as a scanning laser beam to form a display image with scattered light having a wavelength different from that of the coherent light at the illuminated part of the display area.
