Equipped with a nozzle capable of wide-area and high-precision stripe coating
Stripe coater combines the technical know-how of high precision slit nozzles, equipped with large area and high precision stripe coating nozzles.
The stripe coating nozzle gathering ultra-precision processing technology has very small dispersion in the discharge amount from each nozzle hole, it is possible to intermittently apply a stripe-shaped ultrafine wire of minimum 50 μm in thin and with high accuracy .
By application of the coating using this stripe coating nozzle, compared with the photolithography process, the process and coating materials are greatly reduced.
Display field OLED: Light emitting layer (EML), hole injection layer (HIL), hole transport layer (HTL) etc.
