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.
