ISO Class 5 Cleanroom Display Lamination

Optical Bonding Services

Premium custom optical bonding services custom-engineered to ruggedize LCD panels and touchscreens. Performed inside state-of-the-art ISO Class 5 (Class 100) cleanroom environments to eliminate airborne micro-particles. We provide advanced Liquid Optically Clear Adhesive (LOCA / OCR) and Dry Optical Clear Adhesive (OCA) gel lamination. By replacing the internal display air gap with index-matched optical resin, we minimize surface reflections to less than 0.5%, eliminate condensation fogging, and dramatically improve impact and vibration dampening for military, marine, medical, and industrial displays.

Optical bonding services features

Class 100 ISO 5 Cleanrooms

All display alignment, cleaning, and lamination tasks are executed under strict dust-free environmental standards.

Liquid LOCA/OCR Bonding

High-transparency liquid silicone encapsulation designed for large screens, uneven bezels, and custom edge cover glass.

Dry OCA Film Lamination

High-precision dry optical adhesive film sheets optimized for standardized, high-volume flat glass panels.

Multi-Component Stackups

Unified bonding of LCD panels with Projected Capacitive touch panels, transparent ITO heaters, and EMI mesh grid glass.

Index-Matched Compounds

Adhesive resins selected with refraction index (1.41-1.48) matching glass and polarizers to achieve reflections below 0.5%.

Professional Re-bonding

Expert restoration services to de-bond, clean, and re-lamine screens displaying bubble faults or damage.

Custom contract display lamination inside Class 100 cleanroom
ISO 9001:2015 Manufacturing

State-of-the-art contract display lamination and ruggedization

Keetronics provides comprehensive optical lamination solutions to convert standard LCDs into rugged displays. Operating inside our high-purity cleanroom facility, our process eliminates dust defects during the stackup. Liquid silicone lamination cushions the display cell against mechanical shock while maintaining maximum light transmission (>98%). This optical matching improves readability under solar load, increases outdoor contrast by 400%, and permanently eliminates internal condensation and fogging in freezing marine or high-altitude environments.

  • Strict Class 100 (ISO Class 5) cleanroom environments
  • Complete index-matched liquid and dry laminations
  • Integrated touch screens, heaters, and EMI glass layers
  • Complete testing validation under MIL-STD-810G profiles
