Explore our high-performance capacitive and resistive panels engineered for extreme temperatures and severe environments.
Founded in 2010 and located in Guangzhou, China, Guangzhou Xiangrui Optoelectronics Technology Co., Ltd. is a premier manufacturer dedicated to the research, development, production, and custom integration of advanced HMI solutions. We specialize in high-durability resistive touch panels, projected capacitive (PCAP) touchscreens, customized cover glass, and precision module optical bonding products.
Over the past decade, we have built a fully integrated ecosystem providing custom OEM/ODM services to support complex commercial, medical, and industrial systems globally. Backed by both ISO 9001:2015 and ISO 14001:2015 certifications, we align our QA standards with international expectations, catering to applications from multi-parameter medical monitors to payment terminals, rugged outdoor kiosks, and home automation systems.
"We operate on a core foundation of people-oriented, honest, pragmatic, innovative, and enterprising corporate values. Our dedication to implementing advanced new materials and automated lamination processes keeps our clients ahead in fiercely competitive global markets."
A comprehensive technical deep-dive into our material choices, optical performance factors, and controller configurations.
For demanding applications, selecting the appropriate layer stack is critical. We manufacture both GG and GFF configurations depending on the design limits and optical requirements of your custom HMI project:
| Parameters | Projected Capacitive (PCAP) Specs | Resistive Touch Specs |
|---|---|---|
| Touch Detection Method | Electrostatic field disruption (Multi-touch up to 10 points) | Mechanical pressure contact (Single/Dual touch support) |
| Light Transmission Rate | ≥ 87% (Air Bonding), ≥ 90% (Optical Bonding) | ≥ 78% to 82% |
| Hardness Rating | ≥ 6H (Standard), Custom up to 9H (Tempered Cover Glass) | ≥ 3H (Polyethylene Film layer) |
| Operating Life | > 50 Million touches at a single point | > 1 Million touches at a single point |
| Interface Protocols | I2C, USB-HID, RS232 (Industrial EETI/Ilitek controller compatibility) | 4-Wire, 5-Wire analog raw outputs, or RS232/USB controller boards |
Industrial applications frequently introduce challenging operating variables such as water splashes, saline solutions, condensation, and operators wearing heavy protective gloves. Our OEM PCAP touch panels utilize advanced controller chips (specifically tuned EETI or ILITEK ICs) which employ proprietary firmware algorithms:
At Guangzhou Xiangrui Optoelectronics, we operate an advanced 3,000 square meter plant that implements strict cleanroom protocols to ensure the longevity and quality of our optical and capacitive laminate products. Our production floor contains dedicated cleanrooms designed for specific steps of the touch-screen assembly process:
By coupling advanced manufacturing technologies with an localized supply chain network in Guangdong, we provide consistent OEM capacity while minimizing transit and raw material procurement lead times.
Our custom capacitive touch modules are deployed across diverse sectors, engineered to meet specific technical standards.
Fully compliant with hospital sanitation protocols. Designed for multi-touch, glove compatibility, and resilience against continuous chemical cleaning, IPA rubbing, and bleach contact.
Resilient against machine vibrations, high electromagnetic interference (EMI), and ambient operating temperatures ranging from -30°C to +85°C.
Features ultra-thin structures, high optical performance cover glass, customized silkscreen prints, and curved surface integrations for modern consumer environments.
Sunlight-readable displays bonded with UV-resistant coatings. Heavy-impact cover glass certified for IK08 or IK09 mechanical protection against vandalism.
Discover our key developmental vectors designed to support next-generation interactive systems.
Our administrative infrastructure is configured to meet international trade regulations and industrial safety standards.
Guangzhou Xiangrui Optoelectronics holds valid ISO 9001 and ISO 14001 certifications. Our assembly, bonding, and functional test stages adhere to rigorous traceability requirements, confirming each batch matches design blueprints.
All finished products are designed and certified to comply with international RoHS, REACH, CE, and FCC criteria, removing regulatory friction for clients targeting European, North American, and Asian markets.
We provide long-term components supply guarantees (up to 7-10 years production lifecycle consistency) for medical and aviation sectors, preventing issues with component obsolescence.
