Explore our high-performance capacitive and resistive configurations engineered with wide-temperature capability, optical bonding, and IP65-rated structural integrity.
Established in 2010 in Guangzhou, China, Guangzhou Xiangrui Optoelectronics Technology Co., Ltd. has established itself as an authoritative leader in the research, development, and high-precision manufacturing of capacitive and resistive touch solutions. Our operations encompass complete custom touch panels, hardened cover glass, and state-of-the-art optical module bonding.
Guided by rigorous quality systems, our facilities operate under fully certified ISO 9001 and ISO 14001 frameworks. We cater to safety-critical sectors globally, ensuring our touch interfaces satisfy heavy-duty performance requirements across industrial HMIs, diagnostic medical equipment, complex smart home systems, interactive outdoor kiosks, and next-generation biometric palm print verification networks.
Operating from a modern 3,000 square meter facility utilizing Class 100, Class 1,000, and Class 10,000 cleanrooms, our engineering teams oversee every phase of hardware lifecycle from custom substrate design to environmental verification.
Industrial environments present harsh challenges to capacitive touchscreen performance. Electrical noise, moisture, dust, chemical exposure, and fluctuating operating temperatures present challenges to standard consumer-grade touch controllers. Our technological roadmap focuses on overcoming these limitations through material science and micro-engineering.
Utilizing high-density XY sensor grids within the Indium Tin Oxide (ITO) layers, our Projected Capacitive (PCAP) sensors leverage mutual capacitance principles. This detects proximity changes without physical pressure, allowing for multi-touch inputs (up to 10 points) through protective cover glasses exceeding 6mm in thickness.
Industrial deployment demands operation from -30°C to +85°C. We utilize customized optical adhesives (LOCA/OCA) that prevent delamination under extreme thermal cycling, alongside advanced sealing methods to achieve certified IP65 water/dust exclusion.
To mitigate high electromagnetic interference (EMI) from surrounding machinery, motors, or wireless relays, we integrate high-end controllers (such as EETI, Ilitek, and FocalTech chips) that use hardware-level frequency-hopping algorithms and digital noise filtering.

|---|---|---|---|
| Primary Input Method | Pressure-based (Glove, Stylus, Fingertip) | Conductive Contact (Bare hand, thin glove) | Conductive (Thick Glove, Water droplets immunity) |
| Optical Clarity & Luminance | ~75% - 80% (Higher reflectivity loss) | ~85% - 88% (Air-gap internal reflection) | ≥ 90% (Zero internal refractive loss) |
| Impact Resistance (IK Rating) | Low (Sensitive polymer top sheet) | Medium (Standard Cover Glass) | High (Up to IK10, structurally bonded) |
| Operational Lifespan | 35 Million actuations per single point | 50 Million+ actuations | 100 Million+ actuations (Scratch-resistant) |
| EMI/EMC Vulnerability | Highly Immune (Non-conductive detection) | Moderate (Susceptible to high EMI spikes) | Excellent (Active firmware shielding & grounding) |
Guangzhou Xiangrui leverages Southern China's mature optoelectronic ecosystem to ensure raw material availability, low lead times, and manufacturing flexibility. We run automated screen-printing, sensor etching, cover plate cutting, and baking cycles in-house to reduce supply chain delays.
Our cleanrooms (Classes 100 to 10,000) are equipped with constant temperature, humidity, and particle counter sensors. This strict monitoring prevents microscopic contamination, minimizing defects and bubbling during the display module bonding phase (OCR/OCA).
By optimizing the transition from raw ITO sheets to completed touch systems, we deliver cost benefits to our global partners without compromising product quality, helping them meet tight project timelines.
We design, calibrate, and manufacture high-reliability capacitive panels that meet the unique demands of global industrial sectors.
Our medical touch screens support surgical latex glove inputs and remain responsive in wet environments. They are compatible with anti-bacterial cleaning agents and feature chemical-strengthened cover lenses to ensure reliable performance in clinics and diagnostic labs.
Built for 24/7 manufacturing environments, these panels feature high electromagnetic interference (EMI) protection, IK8 to IK10 impact resistance, and wide operating temperature ranges. They ensure reliable, continuous operation alongside heavy industrial machinery.
Equipped with Anti-Glare (AG), Anti-Reflective (AR), and Anti-Fingerprint (AF) surface treatments, our outdoor touch screens maintain readability under direct sunlight. Anti-UV coatings help prevent yellowing and material degradation from long-term solar exposure.
For global procurement teams, choosing a touch screen manufacturer is not just about price. It is about consistent quality, regulatory compliance, and reliable engineering support. Guangzhou Xiangrui has developed a comprehensive support framework to address these needs.
We provide comprehensive CAD, step files, and schematic reviews within 48 hours of initial communication. Our design optimization targets custom cover lens dimensions, tail exit routing, FPC layouts, and tail shielding to streamline integration into your mechanical housing.
We maintain strict quality control by sourcing key materials—such as raw ITO glass, sensor films, control ICs (EETI, Ilitek), and adhesive layers—exclusively from verified partners, ensuring consistent batch-to-batch reliability.
All custom assemblies are manufactured using environment-friendly practices. Our production lines fully comply with RoHS, REACH, CE, and FCC guidelines, simplifying product import and licensing processes in North America and Europe.
We align our production practices with the high quality standards expected by top-tier global manufacturers and system integrators.
We prioritize quality and customer satisfaction, emphasizing on-time delivery and long-term partnerships. This collaborative approach has helped us build lasting relationships with leading global system integrators.
Our ISO 9001 quality management and ISO 14001 environmental management certifications ensure highly standardized processes. From raw materials to final QC inspection, every step is documented for transparency.
Recognized in 2022 as a High-Tech Enterprise in Guangdong Province, we hold over 30 utility and invention patents. Our R&D team continuously works to improve capacitive touch technology, providing innovative solutions for our customers.
