Patent ID: 6936335

Claim:
An addressable receptor, comprising: a rear conductive layer including a plurality of substantially parallel rear electrode strips, each of the rear electrode strips being individually substantially electrically isolated; a front conductive layer including a plurality of substantially parallel front electrode strips, each of the front electrode strips also being individually substantially electrically isolated, wherein a plurality of the front electrode strips comprise an electrically-conductive material that is at least partially transparent to radiation in a selected waveband; the front conductive layer superposed over the rear conductive layer and oriented with respect thereto so as to form an array of electrode regions of intersection corresponding to regions at which the rear electrode strips cross over the front electrode strips; and the rear and front conductive layers separated by a reactive layer, the reactive layer comprising a plurality of predetermined reactive regions, the reactive regions located in a reactive array substantially in register with the array of electrode regions of intersection so that the reactive regions are electrically addressable by coordinate pairs of rear and front electrode strips.
