Cathode ray tube with touch-sensitive display panel

A touch panel assembly comprising

• an insulating plate having an outer surface and an inner surface,
• a plurality of narrow column conductors on said outer surface and a column of first relatively large-area transparent electrodes disposed adjacent to each of said column conductors, said first electrodes also being aligned in rows,
• a plurality of conductive fingers extending from each column conductor to a first electrode adjacent to it, and a plurality of conductive fingers extending from each first electrode toward the column conductor adjacent to it, said first and second fingers being interleaved with each other and disposed in good capacitive coupling relationship while spaced apart a small distance,
• a plurality of rows of second large-area transparent electrodes on the inner surface of said plate, each second electrode lying beneath a first electrode on the outer surface and being capacitively coupled thereto, and
• a narrow row conductor extending along and coupling together the second electrodes in each row on said inner surface.

A cathode ray tube including

• a face plate,
• a touch panel assembly on said face plate comprising
• an insulating plate, adjacent to said face plate, having an outer surface and an inner surface,
• a plurality of narrow column conductors on said outer surface and a column of first relatively large-area transparent electrodes disposed adjacent to each of said column conductors, said first electrodes also being aligned in rows,
• interleaved means intimately coupling each column conductor to the column of first large-area electrodes adjacent to it,
• a plurality of rows of second large-area transparent electrodes on the inner surface of said plate, each second electrode lying beneath a first electrode on the outer surface and being capacitively coupled thereto, and
• a narrow row conductor extending along and coupling together the second electrodes in each row on said inner surface.
