Single-layer organic-light-emitting devices fabricated by screen printing method
Single-layer organic-light-emitting devices (OLEDs) have been fabricated by screen printing method. Using the screen printing method, a polystyrene (PS) film doped with NPB, Alq3, and rubrene was deposited to have the thickness of 100 nm. The film was used for the fabrication of single-layer OLEDs. In order to estimate the performance of the devices, single-layer OLEDs of the same structure were also fabricated by spin coating and compared with those fabricated by screen printing. The spin-coated OLEDs were turned on at 10 V and reached a maximum brightness of 1,100 Cd/m2 at 21 V. The screen-printed OLEDs showed the same turn-on voltage but with a maximum brightness of 110 Cd/m2 at 14 V.
