Display & OLED Manufacturing
Chemistry for Every Display Technology
Display panel manufacturing requires precision photolithography solvents, developers, and organic coating chemicals at every array patterning and organic deposition step.
Key Challenges
What Makes Display & OLED Manufacturing Chemistry Demanding
Large-Area Uniformity
Gen 10.5 substrates require photoresist solvent with uniform evaporation profile. PGMEA with controlled acidity and water ensures uniform film.
OLED Inkjet Printing
OLED organic layer inkjet printing requires ultra-pure DMSO and NMP as carrier solvents with zero metallic contamination.

FAQ
Frequently Asked Questions
What PGMEA grade is needed for TFT-LCD array lithography?
TFT-LCD typically uses G1 or G2 PGMEA (≥99.0–99.9% purity, metals ≤50–10 ppb). The I-line and G-line wavelengths are less sensitive to metal contamination than EUV. G3 PGMEA is recommended for AMOLED applications.
