Display Module Solutions
Gentle, high-efficiency chemistries for display module rework de-gumming, process cleaning, developing, etching and glass thinning without harming ITO/polarizer.
Process Chain
Rework De-gum / De-bond
ACF removal, OCA/LOCA residue removal, UV adhesive de-bonding and polarizer stripping via swelling-peel instead of aggressive dissolution to protect TAC and ITO.
Cold-soak removal of ACF adhesive residue without attacking ITO; works at room temperature with no heating equipment.
Removes OCA/LOCA adhesive residue during screen disassembly and rework without damaging the polarizer.
Rework debonding of UV-cured adhesives for optical and circuit-board parts; compliant alternative free of carcinogenic halogenated solvents.
Chemical stripping of polarizers during display-module disassembly/recycling; alkali bath separates polarizer from glass while protecting the glass substrate.
Process Clean / Develop
Pre-bonding clean, CF clean, PI pre-clean, LC-stage clean and CF developing with low ionic residue and phosphorus-free formulas.
Precision cleaning before IC/display bonding; halogen-free, phosphorus-free, nitrogen-free and flash-point-free, designed to a no-residue standard.
Process cleaning for color-filter lines; safe to ITO, phosphorus-free and APEO-free with a low-foam design.
Substrate cleaning before polyimide coating; respects the PI red line — no hydrolysis or swelling damage to cured alignment layers.
Cleaning for the liquid-crystal stage of panel processes; a three-no standard keeps the LC cell safe.
Color-filter development benchmarked against Nippon Kayaku; fills a near-empty domestic gap for color-filter lines.
Etch & Thinning
ITO patterning etch and Mo/Al line etch for copper processes, plus glass-thinning pre/post treatment across front-end to module.
Pattern etching of ITO for panels and touch; organic-acid route with excellent selectivity to glass, photoresist and black matrix.
Etches Mo/Al wiring in copper-process TFT-LCD lines for 4K2K panels; blended-acid mainstream route balancing etch rate and line profile.
Safety companion for glass thinning lines — pre-thinning pretreatment and post-thinning cleaning on a fluorine-free route.
