Dispensing for Flat Panel Display

Asymtek’s patented jetting technology offers an overall lower cost of ownership by exceeding the dispensing speed of traditional needle dispensing, allowing fewer heads and requiring less tuning and less maintenance.

Jetting is a paradigm shift in dispensing technology:

• Fluid is ejected at high speed out of a nozzle rather than pushed slowly through a needle
• Jetting enables:
• Faster dispensing
• Dispensing into smaller spaces
• Gentle dispensing
• Height insensitive dispensing

Jetting liquid crystal (LC) with Asymtek’s FPD G-4000 system and DJ-100 LC jet:

• ± .5% dispense weight accuracy
• Bottled LC material is attached directly to the jet, eliminating problems with contamination and material waste associated with fluid transfer to syringes
• Up to 16 times faster than needle dispensing

Jetting cell sealant lines and optical fill materials for OLED applications with the DJ-9000 jet:

• 300 mm/sec jetting sealant lines and fill
• Shot rates up to 400 dots/second

Before and After Lamination: 0.6 mm dots
