ABSTRACT:
A display system utilizing a cross-sectionally shaped beam and electric signal to create a desired form by changing the optical characteristics of an electrooptic material. The beam is used to either raise the temperature of a blocking layer adjacent to the electrooptic material and thereby raise the temperature of the material in an area defined by the cross-sectional area of the beam, or it is used to create an electric potential by means of a photoconductor layer adjacent to the electrooptic material, the area of the electric potential being nearly identical to the cross-sectional area of the beam. The beam can be shaped by a template. The beam is directed across the surface of the display panel by means of an X-Y deflecting scanner. A method of manufacturing the display panel using Fezeau fringes is also presented.
