A simple and robust device structure for a flexible, multicolor infrared (IR) display is described. The display operates by optical downconversion
of AC-driven blue phosphor electroluminescence using different-sized,
IR-emitting colloidal quantum dots. Deposition of the IR emissive layer
via inkjet printing facilitates side-by-side multicolor pixel definition
with low material losses.
