Systems and methods for the manufacture of flat panel devices

A method for manufacturing an active matrix device, comprising:

• electrographically forming a first conductive array pattern on an insulating substrate;
• forming a dielectric array pattern over portions of the first conductive array pattern, by a process selected from an electrographic process and a raster deposition process;
• forming a second conductive array pattern over at least portions of the dielectric array pattern by a process selected from an electrographic process and a raster deposition process;
• forming an array of functional devices, each comprising a channel material portion, and a gate portion, by a raster deposition process;
• wherein a channel material of a respective functional device of the array of functional devices is selectively modulated based on signals in the first and second conductive arrays.

A method of forming an active matrix display device, comprising an array of rows and columns, having at each junction a cross-over dielectric separating the respective row and column electrodes, an active modulator selectively responsive to electrical signals in the row and column electrodes, and an electrically modulated optical composition, the method comprising:

• electrographically forming a column conductive array pattern on an insulating substrate;
• forming a cross-over dielectric array pattern over portions of the column conductive array pattern, by a process selected from an electrographic process and a raster deposition process;
• forming a row conductive array pattern over at least portions of the dielectric array pattern by a process selected from an electrographic process and a raster deposition process;
• forming an array of active modulators, each comprising a channel material portion, and a gate portion, by a raster deposition process, proximate to each junction;
• and
• depositing the electrically modulated optical composition configured to be selectively spatially modulated by the array of active modulators dependent on electrical signals in the column conductive array pattern and the row conductive array pattern.
