As a specialist in ultraviolet (UV) curing technology, we know a great adhesive formulation is only half the solution. Pairing it with high-precision, ultra-stable UV-LED curing light sources and automated curing systems is the key to zero-defect production and high yields in optoelectronic display manufacturing.
To support the diverse bonding needs of the display industry — including UV adhesives 3789/3789L, 3761, 3791, 3768, 3730 and 3721 — we deliver tailored, fully automated UV-LED curing equipment for display panel and backlight module manufacturers. Our UV-LED spot, line and area curing systems help the full series of applications achieve second-level curing and automated production upgrades.
Case 1: Galvanized Sheet Fixing for Large LCD Backplates (3789/3789L)
- Challenge: Galvanized backplates dissipate heat quickly; traditional heat curing is slow and risks thermal deformation, and UV light must reach deep structural gaps.
- Solution: High-power UV-LED area/line curing systems with switchable 395nm/365nm wavelengths.
- Results: Deep curing of 3789/3789L in seconds with bonding strength exceeding 12 MPa; cold light source prevents thermal distortion, raising backplate assembly yields.
Case 2: Insulation and Anti-Corrosion for COG/ITO Bonding Areas (3761)
- Challenge: Micrometer-wide circuit lines and thin adhesive layers demand complete curing, otherwise moisture causes corrosion and short circuits.
- Solution: High-precision UV-LED fiber spot light source (365nm) integrated with automated dispensing.
- Results: Spot diameters of 1–5 mm, intensity up to 12,000 mW/cm²; adhesive cross-links in 1–2 seconds and passes Dual 85 (85°C/85% RH) reliability tests.
Case 3: Liquid Crystal Injection Port Sealing for Automotive & High-End LCD (3791)
- Challenge: Sealing adhesive contacts liquid crystals directly, requiring extremely low shrinkage and zero heat transfer to avoid contamination and dark spots.
- Solution: Water-cooled high-uniformity UV-LED curing system.
- Results: 95%+ light intensity uniformity minimizes shrinkage and stress concentration; temperature rise within 3°C delivers 100% leak-proof sealing.
Case 4: Foldable Screen & FPC Bonding Point Protection (3768)
- Challenge: Reinforcement adhesive at FPC bending zones needs both high adhesion and flexibility; under-curing peels and over-curing cracks.
- Solution: Smart-Cure multi-stage intelligent energy control system.
- Results: Dual-stage irradiation (low-intensity pre-curing then high-intensity main curing) matches 3768 flexibility; cured points withstand over 100,000 dynamic bending cycles.
Case 5: LED Lens Bonding for TV Light Strips (3730)
- Challenge: High-viscosity 3730 (40,000 mPa·s) needs rapid curing at 1200 mJ/cm² without yellowing.
- Solution: In-line continuous UV-LED conveyor curing tunnels and high-power line light sources.
- Results: Irradiance above 2000 mW/cm² reaches the curing threshold in seconds with zero lens displacement; pure 365nm/395nm spectrums keep transmittance above 99%.
Case 6: Micro-Encapsulation & Thin-Layer Protection for OLED / Micro-LED (3721)
- Challenge: Thin-layer encapsulation demands precise adhesive thickness and curing flatness on heat-sensitive substrates.
- Solution: Low-temperature ultra-thin UV-LED curing module with integrated water cooling.
- Results: Fanless operation eliminates vibration and surface ripples on micro-volume adhesive drops, forming an extremely thin, high-density moisture barrier for OLED and wearable devices.
