ABSTRACT:
A display system suitable for large color television type images in which a thin membrane is charged electrostatically in a pattern corresponding to the image. The membrane is deformed locally by electrostatic force and the image is rendered visible by an optical arrangement in which the deformation varies the light transmitted through the display, the rear of which is illuminated.
