<p>Display (A) based on photoluminescence display element (PQD), with substrate (1) and emitter layer (4) between front transparent and back electrode layers (2, 5), has hole-blocking layer (7), between (4) and (2), with highest occupied molecular orbital of lower energy than that of (4). (7) consists of zirconium, hafnium, tin, tantalum, titanium or zinc oxide and/or zinc sulfide and (5) of gold, palladium, platinum, transparent conductive oxide and/or nickel. Independent claims are also included for the following: (1) display (B) based on photoluminescence display element (PQD; photoluminescence quenching device), with substrate (1), emitter layer (4) and electrode layers (2, 5) as in (A), which has a hole-blocking layer (7) between (4) and (5) and/or an electron-blocking layer (6) between (4) and (2), with highest occupied molecular orbital of (7) of lower energy than that of (4) and /or lowest unoccupied molecular orbital of (6) of higher energy than that of (4), where electrode (2) acts as cathode and (5) as anode of the display; (2) PQD as in (A), with organic light-emitting material; (3) PQD as in (B), with organic light-emitting material; (4) method of converting signal voltages into optical image data.</p> |
