LOCA & Dry-Film Optical Lamination

Optically Bonded Displays

High-performance optically bonded displays and rugged touchscreen monitors engineered with advanced Liquid Optically Clear Adhesive (LOCA) or Optical Clear Resin (OCR) face-to-face lamination. By completely filling the internal air gap between the LCD panel and the touch sensor or protective cover glass, we achieve index-matched refraction that slashes specularity reflection from 8% down to less than 0.5%. This delivers unmatched readability under direct sunlight and high-ambient lighting, blocks moisture condensation, dust, and internal fogging, and dramatically improves impact resistance by distributing shock energy across the laminated stack.

Optically bonded display features

Eliminated Internal Air Gap

Fills the space between LCD and glass with index-matched optical adhesive, blocking dust ingress and internal condensation.

Ultra-Low Reflection

Reduces light reflection from ~8% down to less than 0.5%, keeping images sharp and readable in high-glare environments.

Superior Impact Resistance

The elastic bonding layer acts as a mechanical shock absorber, dispersing impact forces and preventing glass shattering.

Reduced Parallax Error

Brings the display pixels closer to the front glass surface, optimizing tactile touch precision and viewing angles.

Advanced UV Filtration

Integrates UV blocking filters inside the adhesive gel to prevent solar yellowing and panel degradation.

Extreme Ingress Protection

Fully sealed IP67/IP68 structures guard sensitive optical layers against water splash, salt mist, and pressure washing.

LOCA & Dry-Bond Technology

Engineered to eliminate glare, fogging, and parallax

Standard air-gap displays suffer from internal light refraction, causing severe washout under daylight. Our optical lamination process bonds the glass and panel into a single unified stack. Using index-matched refractive compounds, we ensure that light travels cleanly through the layers, enhancing contrast ratio by up to 400% in bright sun. Additionally, the complete absence of air makes it impossible for moisture to condense between layers, guaranteeing crystal-clear vision in freezing humidity, naval bridges, and aerospace cabins.
