Details
Inventors: Yevick, George J.;
Assignee: Izon Corporation (Stamford, CT)
Primary Examiner: Bauer; Edward S.
Assistant Examiner:
Attorney, Agent or Firm: Greer, Jr.; Thomas J.

An electro-optic device having utility in (a) the display of parallel information such as a projected microimage, and (b) both the display and recording of series information such as TV signals. The device includes a photoconductive sheet and an electro-optic sheet (and may also employ a gravure lattice member) and carries X and Y addressors.

DETAILED DESCRIPTION What is claimed is: 1.
An electro-optic device of the type having a photoconductive sheet and an electro-optic sheet both generally planar, the improvement comprising, generally planar X and Y sets of transparent and conductive addressor strips, the X and Y sets sandwiching the photoconductive sheet and the electro-optic sheet.
2.
The device of claim 1 including means for illuminating the X addressor strips from a direction exteriorly of the sandwich towards the sandwich and into the plane of the X addressor strips.
3.
The device of claim 2 wherein said illuminating means does not illuminate the interstices between the X addressor strips.
4.
The device of claim 1 wherein the photoconductive sheet is in the form of a rectangular array of discrete photoconductive elements, the columns of the array being aligned with the X addressor strips.
5.
The device of claim 4 wherein the discrete photoconductive elements respond to different colors, and including a reflecting sheet positioned between the photoconductive sheet and the electro-optic sheet.
6.
The device of claim 4 wherein the discrete photoconductive elements respond to different colors, and including a generally rectangular array of electrically conducting rods mirrored at their ends which face the electro-optic medium.
7.
The device of claim 1 wherein the electro-optic sheet is in the form of a rectangular array of discrete electro-optic elements, the columns of the array being aligned with the X addressor strips.
8.
The device of claim 7 wherein the electro-optic elements are normally opaque and changing to a scattering color state when impressed with an electric field, and wherein the X addressor strips are themselves color filters of different colors.
9.
The device of claim 1 including means for defining a gravure lattice array of points of rectangular form, said means defined by an array of electrically conducting cylinders, each column of the gravure array being aligned with an X addressor strip.
10.
The device of claim 1 including an opaque sheet positioned between the photoconductive sheet and the electro-optic sheet, the opaque sheet precluding ambient light from passing through the electro-optic sheet to the photoconductive sheet
