Stripe coater

Application for Large OLED TV etc, Large area and high precision micro-stripe-coating capable

Stripe coater is a high-precision coater equipped with a high-precision and wide-area coating capable stripe-nozzle: the cream of slit-nozzle technology and know-how. Forming block-shaped coated area by intermittent coating realizes multi-panel production from a large mother-glass. High-precision alignment technology is incorporated in the stripe coater to perform stripe-coating on a large substrate.

Schematic view

The stripe coater can perform coating of a coating-type organic EL material (wet process OLED material), forming the thin and divisional film of emission layer (EML), hole-injection layer (HIL), and hole-transfer layer (HTL).
