Abstract
An optical electrical system that converts a photo image pattern to a conductance pattern comprises a photoconductive layer for receiving light image patterns and a conversion layer for converting an electrostatic voltage into a conductance pathway for a current flow. The light image pattern can be generated into a page sized area and generated from a light source comprising an array of projectors coupled together.

An optical electrical device for converting a photo image pattern to a conductance pattern providing virtual electrodes and virtual interconnects, comprising:
- a lighting arrangement for generating a predetermined optical image in the form of a virtual electrode and virtual interconnect pattern;
- a photoconductive component including a photoconductive layer, and active semiconductor layer and an insulating layer, the photoconductive component positioned to receive the optically induced virtual electrode and virtual interconnect pattern projected therein, and configured to form a charge where the virtual electrode and virtual interconnect pattern is received;
- a positioning arrangement configured to position the virtual electrode and virtual interconnect pattern at a predetermined location on the photoconductive component to allow for connection to connection points of discrete components;
- and
- an erasure component positioned and configured to erase the images on the photoconductive component.
An optical based system having virtual electrodes and virtual interconnects:
- a light beam source for generating a light beam;
- a microdisplay chip configured to receive the light beam from the light beam source, wherein the microdisplay chip is positioned and configured to project an image of a virtual electrode and virtual interconnect pattern;
- a focusing component configured to generate a projection beam of the virtual electrode and virtual interconnect pattern from the projected image of the microdisplay chip;
- a photoconductive component positioned to receive the projection beam, to create a projected light image pattern in the photoconductive component, the projected light image defining a virtual electrode and virtual interconnect pattern;
- and
- a camera arrangement positioned to image a top surface of the photoconductive component.
