Abstract

For potential applications in large-area organic light-emitting diode (OLED) displays, solar cells, sensors, and secondary batteries, we have developed a slot-die coating process that allows control of coating width and continuous coating. In a sheet-to-sheet (S2S) type coating system, coating width adjustment and continuous coating processing are highly demanded to improve productivity and automate the coating process. To control coating width, we have proposed a shim plate with a narrower outlet width and a dual plate slot-die head (DP-SDH) with a meniscus guide. For continuous coating process, we have attempted a lip dipping method and a motorized cleaning module method. Finally, using the DP-SDH and motorized cleaning module method, we have successfully fabricated a poly(3,4-ethylenedioxythiophene):poly(styrenesulfonate) (PEDOT:PSS) film with a width of 150 mm, despite the head-lip width being 200 mm.
