Explore our highly reliable, optically bonded capacitive and resistive tactile panels engineered to elevate operational performance across demanding industries.
Founded in 2010 in Guangzhou, China, Guangzhou Xiangrui Optoelectronics Technology Co., Ltd. has established itself as an elite pioneer in the research, development, and manufacturing of high-performance resistive touch panels, projected capacitive (PCAP) touch screens, cover glass custom modifications, and advanced optical module bonding.
Spanning a state-of-the-art facility of 3,000 square meters (with a total operational factory layout expanding up to 10,000 square meters), our plant is equipped with ultra-clean, dust-free workshops operating across Class 100, Class 1,000, and Class 10,000 levels. This multi-tiered environment ensures optimal yields and guarantees that sensitive processes like optical bonding and micro-glass laminations are free from microscopic contaminants.
Through rigorous engineering audits, we have obtained prestigious certifications including ISO 9001:2015 for Quality Management and ISO 14001:2015 for Environmental Management. In 2022, we were officially recognized as a "High-Tech Enterprise" in Guangdong Province, backed by a robust intellectual property portfolio that features over 30 utility model and invention patents.
The 15-inch display diagonal has solidified its position as the golden standard for Human-Machine Interfaces (HMI). It represents the optimal equilibrium between visual real estate, power efficiency, and physical packaging constraints. In modern industrial ecosystems, we are witnessing rapid migration from basic tactile inputs to ruggedized, multi-layered capacitive and specialized 5-wire resistive sensor nodes.
Leveraging multi-touch matrices, PCAP sensors facilitate advanced gestures such as pinch-to-zoom, swipe, and rotation. Built with high-ion exchange aluminosilicate cover glass, these screens withstand extreme physical abuse while offering over 90% light transmittance.
For environments plagued by severe electromagnetic interference (EMI) or where operators wear heavy insulated gloves, 5-wire resistive screens remain the undisputed choice. Unlike capacitive sensors, they rely on pressure activation, rendering them immune to water droplets, oil splashes, and electrical noise.
Traditional air bonding (frame fitting) leaves a micro-gap between the LCD panel and the touch overlay. High-end industrial integrations utilize optical bonding (using Liquid Optically Clear Adhesive - LOCA or sheet OCA). This fills the internal air gap, mitigating reflections, preventing dust/moisture condensation, and increasing shock resilience by up to 300%.
Procuring 15-inch industrial touch interfaces is not merely a transaction; it is a long-term integration strategy. When enterprise procurement and design engineers evaluate potential suppliers, the technical criteria transcend standard consumer benchmarks. Sourcing directors must ensure that products meet stringent parameters to avoid expensive line shutdowns and recall cycles.

A touch interface must conform to the operational realities of its targeted deployment. Sourcing teams select 15-inch modules based on specialized compliance parameters unique to specific business fields.
In operating theaters and patient monitoring units, touch screens must tolerate chemical disinfectants (including isopropyl alcohol, bleach, and hydrogen peroxide) without surface erosion. Our PCAP products feature high-noise immunity controllers (EETI/ILITEK) configured to support thick multi-layer medical latex gloves, ensuring uninterrupted performance during life-critical operations.
Machining, chemical manufacturing, and assembly line terminals subject display components to heavy mechanical vibrations, fine metallic dust, and liquid splatters. By implementing 5-wire resistive and heavy-duty IK08-rated glass-on-glass capacitive sensors, our products prevent accidental touch events caused by grease buildup or surrounding magnetic interference.
Self-service ticketing machines, gas station pumps, and palm-print payment systems demand high sunlight legibility and physical security. We configure custom cover plates up to 6mm thick with anti-vandalism ratings (IK10) and combine them with 1000+ nits high-brightness LCD backlights and UV-blocking optical adhesives to prevent panel yellowing under direct sunlight.
Shipping custom electronic products across borders involves complex regulatory frameworks. An OEM supplier must not only possess raw manufacturing capabilities but also demonstrate conformity to international standards to prevent border customs seizures or end-user liability.
Our raw materials, cover glass, optical adhesives, flex cables, and controller assemblies undergo strict laboratory testing. They conform to environmental restrictions (RoHS/REACH) and emit electromagnetic radiation within safe limits (FCC Class B and CE standards).
Every phase of our production—from incoming quality control (IQC) of ITO film and glass substrates, to process quality control (IPQC) inside cleanrooms, to final quality assurance (FQA)—is recorded and traceable, minimizing post-shipment failure rates to < 0.2%.
We provide localized technical assistance. This includes custom firmware tuning for EETI, ILITEK, FocalTech, and Goodix ICs. We also optimize controllers to ignore water droplets, recognize thick gloves, and conform to target chassis designs.
Guangzhou Xiangrui Optoelectronics Technology Co., Ltd. prides itself on a foundation of integrity, practicality, and customer-first operations. We maintain long-term partnerships with leading domestic and international enterprises by ensuring deliveries are made on time, every time.
Our dedicated R&D department continues to win prestigious local contracts. Our 2022 high-tech enterprise designation reflects this commitment, guaranteeing that our clients receive the most advanced and cost-effective touch solutions available in China today.
The landscape of touch interaction is evolving beyond traditional 2D surface sensing. Our R&D pipeline is actively addressing next-generation interface technologies, ensuring that our OEM clients remain at the forefront of human-machine interaction.
To restore the tactile assurance of physical keys on glass surfaces, we are integrating piezo-electric and electrostatic actuators into 15-inch touch screen overlays. Operators receive localized vibrational confirmation upon virtual button presses, drastically reducing errors in medical and heavy industrial applications.
By utilizing metal mesh and silver nanowire technologies in place of traditional Indium Tin Oxide (ITO), we are creating lighter sensor sheets. These materials offer superior resistance to bending and micro-cracking under severe temperature swings.
Aligned with public hygiene standards and secure payment terminals, our display packages incorporate near-field optical sensors. These modules support both contactless hand gestures and biometric palm print identification, facilitating highly secure payment systems.
