Engineered with advanced optical bonding to eliminate reflection and withstand harsh environments.
The Netherlands sits at the absolute epicenter of Europe’s high-tech machinery development. From the advanced semiconductor cluster in Eindhoven (Brainport Region) to maritime system integrations in Rotterdam, and computerized agricultural greenhouse technologies in the Westland region, the demands on Human-Machine Interfaces (HMIs) are exceptionally stringent.
Standard air-bonded displays suffer severely under Dutch maritime conditions, high-humidity agricultural greenhouses, and sterilized medical environments. When light transitions between different materials (e.g., from cover glass to the air gap, and then to the LCD panel), the changes in refraction index cause severe light scattering and reflection, rendering displays unreadable in outdoor sunlight or bright operating theaters.
Guangzhou Xiangrui Optoelectronics Technology Co., Ltd. bridge this technical gap. By using high-performance optical bonding (using refractive-index-matched LOCA/OCR or OCA), we eliminate the air gap between the touch layer and the display. This optimization reduces light reflections from roughly 4.5% down to less than 0.2%, dramatically improving readability, contrast, and structural ruggedness.
A comparison of structural approaches designed to meet strict European quality standards.
| Parameter | Air Bonding (Tape Bonding) | OCA Bonding (Dry Process) | LOCA / OCR Bonding (Wet Process) |
|---|---|---|---|
| Optical Performance | Moderate (4.5% reflection) | Excellent (<0.5% reflection) | Outstanding (<0.2% reflection) |
| Condensation & Dust Ingress | Highly Susceptible | Hermetically Sealed | Hermetically Sealed |
| Mechanical Shock Resistance | Poor (Air gap cushions nothing) | Good (Polymer film padding) | Superior (Liquid adhesive shock absorption) |
| Suitable Sizes | All sizes | Generally <15.6 inches | All sizes (Up to large industrial sizes) |
| Reworkability | High | Difficult | Moderately Reworkable (Highly controlled) |

For applications within the Netherlands’ industrial sector, selecting the precise adhesive medium is critical:
Our custom optical bonding solutions are optimized for several demanding Dutch market applications.
Designed for Rotterdam’s extreme maritime conditions. Prevents internal condensation (fogging) in marine bridges and features saltwater corrosion resistance, high UV stability to prevent yellowing, and high sunlight readability.
Optimized for medical equipment in Dutch hospitals. Optical bonding prevents dynamic light scattering inside operating theaters, while supporting gloves-on capacitive touch and chemical resistance to aggressive disinfectants.
Engineered for high-temperature and high-humidity environments. Features full IP65 rating compatibility, specialized condensation avoidance, and high touch accuracy under running moisture.
Established in 2010, we are a leading developer and manufacturer of industrial-grade touch screens and optical bonding technologies. Our facilities in Guangzhou, China span 3,000 square meters of production space (part of our 10,000 square meter factory layout), tailored for the high-end European export market.
Unlike standard assembly shops, we control every step of the processing lifecycle: from raw cover glass cutting and tempering to ITO sensor design, and the final optical bonding assembly. Our class-certified cleanrooms eliminate dust and particulates down to 0.1 microns, guaranteeing that zero artifacts are trapped between the glass and the display panel.
By obtaining ISO 9001 and ISO 14001 certifications, we conform strictly to international quality and environmental management standards. In recognition of our technical innovations, we were awarded the official title of **Guangdong Province High-Tech Enterprise** in 2022.
Optical bonding quality is directly tied to the cleanliness of the air. Microscopic dust particles can cause display failure, pixel occlusion, and delamination over time. We maintain dedicated cleanrooms designed for different production stages:
Used for liquid resin dispensing and core optical layering steps.
Used for touch panel pre-alignment, laminating, and autoclave treatment.
Used for incoming component preparation, test staging, and packaging.

High-humidity environments are prone to severe condensation inside the air gap of traditional displays. By completely filling this space with an optical adhesive layer, moisture cannot penetrate the assembly. This eliminates internal fogging, protects the electronics from moisture damage, and ensures reliable touch performance under humid conditions.
LOCA is a liquid resin that conforms to surface variations, such as ink steps or bezel designs on cover glass. This ensures complete wetting and bubble-free adhesion, even on uneven surfaces. For large screens (above 15.6 inches) or thicker cover glass with high print steps, LOCA provides superior stress relief, helping prevent display distortion and bubbles during thermal expansion.
In a standard air-bonded display, light reflections occur at each material interface (glass-to-air, air-to-LCD), resulting in a reflection rate of about 4.5% that degrades visibility in bright environments. Optical bonding index-matches the adhesive to the glass and display layer, eliminating the air gap. This reduces reflection to less than 0.2%, maintaining readability without requiring high-backlight, energy-intensive displays.
Our optical bonding is performed inside Class 100, Class 1,000, and Class 10,000 cleanrooms. Dispensing and laminating are completed in Class 100 areas to keep the optical interface free of microscopic dust. Our facilities are certified to ISO 9001 and ISO 14001 standards, ensuring consistent, high-yield production that meets European import regulations.
Yes, we provide full customization options, including custom shapes, holes, printing designs, glass thickness, surface coatings (Anti-Glare, Anti-Reflective, Anti-Fingerprint), and specialized display interfaces to suit your application requirements.
