Introducing our high-performance optical bonded touchscreen displays, designed to deliver exceptional clarity and ruggedness in high-ambient and direct sunlight environments. By eliminating the air gap between the display panel and the touch sensor overlay using premium Liquid Optical Clear Adhesive (LOCA/OCR) or dry film (OCA), we reduce internal light reflections down to 0.2%. This prevents dust/moisture ingress and internal fogging, while enhancing mechanical impact absorption (up to IK09).
Replaces the internal air gap with a refraction-matched index adhesive, lowering internal reflection from 4.5% to under 0.2%.
Fully sealing the space between display and cover glass prevents humidity buildup, eliminating display fogging in sub-zero or humid conditions.
The cured elastomeric optical adhesive layer acts as a shock absorber, increasing the display's mechanical resistance up to IK09.
Improves luminance efficiency and contrast ratios under direct sunlight without requiring excessive LCD backlight power.
Formulated with adhesives possessing refractive indexes (n ≈ 1.41 - 1.49) tailored to perfectly match PMMA, cover glass, and polarizer substrates.
Employs non-yellowing polyurethane and silicone adhesives tested under intensive UV chamber exposures to ensure long-term clarity.
Optical bonding is the process of applying a layer of transparent adhesive between the touch sensor panel and the LCD cell. Standard displays have an air gap that causes multiple light refractions, reducing readability and letting in moisture. Keetronics uses Class 100 cleanroom environments and automated liquid dispensing systems to laminate display stacks, resulting in a single solid-state assembly with premium optical performance.
Uses micro-thin pre-cut pressure-sensitive sheet adhesives, ideal for flat, high-volume capacitive screens.
Liquid resin dispensing that conforms to uneven surfaces, bezel frames, and 3D display curves.
Tailored ultraviolet wave exposure profiles that cure the adhesive layers uniformly without inducing thermal stress.
Enhances the optical bond by adding a micro-thin metal oxide layer to the front cover glass to cancel reflections.
Tailor the industrial monitor enclosure, cover glass, and video card configurations to your system.
