Explore our leading industrial capacitive and resistive touch panels integrated with premium cover glass and advanced optical bonding.
The global commercial and industrial sectors are shifting dynamically toward complex, multi-touch Human-Machine Interfaces (HMIs). Modern industrial processes are no longer confined to clean air-conditioned control rooms. Today, high-quality industrial touch panels are deployed in extreme outdoor marine environments, sterile medical operating rooms, high-vibration manufacturing plants, and heavy-duty logistics systems.
To satisfy the rigorous operating standards of modern factories, touch screens must withstand mechanical abuse, electrostatic discharges (ESD), water droplets, chemical washes, and broad temperature fluctuations. The integration of Projected Capacitive (PCAP) and advanced Resistive touch screens represents the cutting edge of industrial hardware, ensuring fail-safe reliability where system downtime can cost thousands of dollars per minute.
Furthermore, the addition of optical bonding (OCA/LOCA) directly eliminates internal air gaps between the LCD panel and the cover glass, dramatically reducing light refraction, eliminating condensation issues, and offering exceptional anti-glare, anti-reflective, and impact-resistant properties.
Guangzhou Xiangrui Optoelectronics Technology Co., Ltd. is a global pioneer in custom industrial touch screen manufacturing.
Founded in 2010 and located in Guangzhou, China, we are a company dedicated to the research and development, production, sales, and service of resistive touch panels, capacitive touch panels, cover glass, and module bonding products. We provide customized production of various touch screens, as well as comprehensive OEM and ODM services to global customers.
Our corporate philosophy is based on the fundamental purpose of being people-oriented, honest, pragmatic, innovative, and enterprising. Sincere and united, our team strives continuously to expand our technologies. Since its establishment, the company has been committed to the development, research, and application of new products, new processes, and new materials, relying on a professional R&D team, rich production experience, and high-quality service. This dedication ensures that our enterprise maintains its competitive edge in fierce global market competitions, achieving rapid and stable long-term development.
To satisfy specialized manufacturing standards, the total plant area of the company is about 3000 square meters (with overall facility capabilities extending up to 10,000 square meters). We feature structured business units including our dedicated R&D department, Production department, Marketing department, Quality department, Finance department, Purchasing department, and Human Resources department.
Our cleanroom facilities are uniquely designed to fulfill the dust-free level requirements for different production processes. Optical bonding of touch modules and cover glasses requires an environment free from microscopic airborne particles. Dust particles trapped inside a laminated touch display degrade optical performance, leading to visual defects and elevated failure rates in high-reliability fields.
Guangzhou Xiangrui Optoelectronics utilizes advanced air filtration, positive pressure control, and static dissipation systems. Each operator complies with strict cleanroom protocols, wearing anti-static garments. By maintaining strict control over temperature, humidity, and particle levels, we ensure every capacitive and resistive touch panel exceeds international quality guidelines.
How our customized HMI panels address high-reliability, compliance, and design requirements across global industries.
Equipped with IP65-rated bezel-free designs, our touch screens withstand industrial fluids, constant vibrations, and intense electromagnetic interference. Built-in wide temperature tolerances (-20°C to +70°C, and custom -40°C to +85°C options) prevent lockups or responsiveness failures in extreme environments.
We customize glass surfaces using Anti-Glare (AG), Anti-Reflective (AR), and Anti-Fingerprint (AF) coatings. Our capacitive sensors support gloved operation (latex, nitrile, heavy surgical gloves) and fluid rejection, allowing safe operation with liquids on the screen surface, certified to medical safety standards.
With high optical transmittance and durability, our glass-on-glass and film-on-glass custom capacitive screens are widely adopted in smart retail kiosks, access points, and palm print recognition systems, ensuring fast, accurate scanning under varied indoor and outdoor lighting.
Procurement teams face difficulties sourcing HMIs that balance technical compliance with supply chain longevity. Industrial projects often require a continuous supply of identical components for 5 to 10 years.
Our company addresses this need through strict lifecycle management. We provide full customization, including custom cover glass thickness (from 0.7mm to over 6mm), chemically strengthened glass, IK08 to IK10 impact protection, custom FPC routing, Controller IC brand selection (EETI, Ilitek, FocalTech), and bespoke bezel printing.
By sourcing raw materials directly and performing key processes in-house, we secure stable pricing, reliable manufacturing schedules, and consistent product delivery for our global partners.
A dedication to high quality, regulatory compliance, and customized technology.
Our business strategy is defined by a dedication to quality first, customer focus, timely delivery, and long-term partnership. We maintain stable relationships with top-tier industrial firms and component suppliers to ensure reliable component availability.
We have passed ISO9001 quality management system and ISO14001 environmental management system qualification certification. Our production processes are standardized to guarantee that products conform to high quality standards from raw materials to final QC inspection.
Under the leadership of our R&D department, we have repeatedly obtained utility model patents and invention patents, winning the Guangdong Province title of "High-Tech Enterprise" in 2022.
Our production processes conform to RoHS and REACH directives, ensuring all products are free from restricted hazardous materials and meet environmental standards.

The future of industrial touch screens is defined by the integration of smart sensors, haptic feedback, and flexible designs. Our R&D team is developing hover-sensing capacitive technology, allowing operation without physical surface contact. In addition, we are designing antimicrobial cover glasses to reduce surface contamination risks in medical HMIs and public-use kiosks.
