Explore our core industrial grade touch panels featuring IP65 resistance, optical bonding, and wide operating temperature profiles.
Setting Benchmarks in Resistive & Capacitive Interface Technologies Since 2010
Founded in 2010 in Guangzhou, China, Guangzhou Xiangrui Optoelectronics Technology Co., Ltd. stands as a premier specialized designer and manufacturer of high-durability human-machine interfaces. We focus on custom resistive touch panels, projected capacitive (PCAP) touch screens, bespoke cover glass decoration, and state-of-the-art optical bonding processes.
With an unwavering focus on research, development, and stringent quality control, we support industrial, medical, consumer, and transport systems around the world. We offer comprehensive OEM/ODM solutions tailored to exact physical parameters, environmental stresses, and electrical architectures.
Our plants operate under strict ISO 9001:2015 and ISO 14001:2015 systems. This ensures every raw glass sheet, sensor grid, and liquid optically clear adhesive (LOCA) undergoes standardized trace inspections to eliminate field failure risks.
Production facilities in Guangzhou featuring cleanroom spaces for precision optical-bonding operations.
Optical touch buttons project light paths beneath or along the glass panel. When a finger interrupts the light pattern, sensors immediately register a touch. This method eliminates physical wear and allows for operation under very thick cover lenses or with protective gloves.
By using conductive micro-fine grid matrices on ITO layers, capacitive sensors read tiny variations in electrostatic fields. This technology supports multi-touch tracking, high optical clarity, and swift response times, making it the industry standard for consumer and medical displays.
Optical bonding fills the air gap between the touch sensor and the display using LOCA or sheet adhesives. This setup reduces internal light reflection by up to 99%, enhances sunlight readability, prevents internal condensation, and boosts physical drop-test durability.
In standard consumer devices, basic capacitive touch is standard. However, industrial control, smart kiosks, and medical environments present unique challenges like chemical cleaners, high humidity, thick protective work gloves, and electrostatic discharge (ESD) spikes. Custom optical touch buttons solve these issues by isolating the sensor array behind solid protective cover glass, achieving extreme longevity without sacrifice.
Additionally, custom-configured optical touch buttons mitigate accidental actuation issues from falling dust, water spray, or grease. Our research indicates that using optical touch arrays can improve Human-Machine Interface (HMI) reliability in rugged field applications by up to 40% compared to traditional resistive films.
Minimizing particulates is crucial for optical bonding and touch panel lamination. The smallest dust mote can cause optical distortion, bubble formation, or micro-circuit breaks. To guarantee optimal performance, Guangzhou Xiangrui operates dedicated cleanrooms certified from Class 100 to Class 10000:
Our manufacturing plant spans over 3000 square meters, structured with separate operational units including Quality Assurance, R&D, Purchasing, and Marketing. This modular setup allows us to coordinate custom engineering requests, scale production, and deliver reliable solutions to global industrial OEMs.
As a seasoned supplier, Guangzhou Xiangrui is structured to meet the strict technical standards of various industries. We offer specialized layouts and material configurations based on industry needs:
Our capacitive panels support thick glass configurations, ensuring seamless operation even when doctors or nurses wear thick latex gloves. The sealed designs are fully compatible with regular medical alcohol and chemical sanitizers without degrade.
Designed to resist electromagnetic interference (EMI) from heavy machinery. Our wide-temperature operations run reliably from -40°C to +85°C, ensuring durability against industrial heat, vibrations, and grime.
Water droplets and sunlight readability are major issues for outdoor touchscreens. Our IP65/IP66 optical bonding, combined with UV filters and anti-glare coatings, guarantees reliable touch input in rain, snow, or direct sunlight.
We streamline sourcing for international buyers. With custom-engineered samples, detailed technical schematics, and ISO-compliant documentation, we simplify qualification cycles. Our products are exported to over 40 countries, and we partner with global logistics networks to offer secure packaging, customs clearance, and DDU/DDP delivery terms.
Our design approach centers on long-term reliability. We focus on building lasting relationships with top manufacturers by providing consistent product quality and on-time delivery.
We operate in strict accordance with ISO 9001 and ISO 14001 guidelines, meaning our panels go through rigorous quality control checks from raw materials to final functional tests.
Our dedicated R&D department regularly develops custom utility designs and structural enhancements, securing over 30 patents for touch technologies.
Recognized officially in 2022 as a High-Tech Enterprise of Guangdong Province, reflecting our commitment to materials research and HMI innovation.
As human-machine interfaces advance, simple touch detection is evolving into smarter, multi-functional control points. Our engineering roadmap targets four key developmental sectors:
Adding micro-vibrations to optical and capacitive buttons to give users tactile confirmation, making operations safer in industrial environments.
Smart firmware adjustments that automatically tune sensitivity depending on environmental factors like water spray, dust build-up, or glove thickness.
Developing flexible glass laminates and high-strength chemically strengthened glass to create ultra-thin, durable touch structures.
Using eco-friendly, lead-free processes and energy-efficient lamination systems to support corporate green initiatives.
