Plastic retina

To build a full plastic retina, the polymer grid triode image enhancement array would be fabricated directly onto the output (back) side of a photodetector array (for example an infrared detector array) using each detector output pad as the anode or cathode of the PGT at that node. The semiconductor layers would be cast sequentially from solution and applied onto the detector array much like an antireflection coating. The final contrast enhanced output would be connected to a demultiplexer by bump-bonding that is by cold-welding indium bumps arrayed reciprocally on die PGT array output and on e demultiplexer input.
