Roll-to-Roll Fabrication of PEDOT:PSS Stripes Using Slot-Die Head With $mu$ -Tips for AMOLEDs

Stripe coating offers an approach to remove the pixel bank structure used to confine ink droplets. For potential application in solution-processable active-matrix organic light-emitting diode displays, we fabricate fine and dense stripes of poly(3,4-ethylenedioxythiophene): poly(4-styrenesulfonate)(PEDOT:PSS) using a slot-die head with the dual plate (shim plate with slit channels and meniscus-gui...
