Engineered for extreme performance, featuring advanced IP65 protections, wide-temperature ranges, and precise optical bonding technologies.
Founded in 2010 and based in the high-tech manufacturing hub of Guangzhou, China, we are a premier national high-tech enterprise dedicated to the R&D, fabrication, sales, and full-service integration of resistive touch panels, projected capacitive (PCAP) touch screens, bespoke cover glass (CG), and comprehensive liquid optical bonding modules.
As a certified ISO 9001 and ISO 14001 manufacturer, we operate customized production lines to deliver advanced OEM and ODM services. Our hardware products are purpose-built to operate flawlessly in challenging applications across industrial controls, military-grade systems, high-precision medical diagnostics, rugged outdoor kiosks, smart home intelligence, and palmprint-recognition biometric payment systems.
To satisfy highly specialized application environments, we own and manage cleanroom facilities ranging from Class 100 (ISO 5), Class 1000 (ISO 6) to Class 10000 (ISO 7). This ensures strict airborne particulate control for precision optical processes such as OCA/LOCA optical bonding, film sensor lamination, and cover sheet structural integrations.
Critical selection criteria and technical parameters for procurement officers and engineering leads.
Industrial procurement teams require screens that withstand dust, chemical washing, and physical impacts. Our capacitive touch screens feature up to IP65 ingress protection ratings, utilizing thick, impact-resistant cover glass (IK08+ ratings) to withstand high mechanical shock, grease, and fluid exposures.
Industrial facilities contain severe EMI generated by heavy machinery. Using advanced IC solutions (such as EETI, Ilitek, and Microchip controllers), our custom capacitive panels deliver superior noise immunity (compliant with high EMS limits), enabling multi-touch functionality even when operating with thick safety gloves or water drops on the glass surface.
Unlike consumer-grade components, industrial control panels require product lifetimes spanning 7 to 10 years. Guangzhou Xiangrui provides extensive lifecycle protection programs. We establish strict component design control and backup channels to guarantee form-fit-function replacement availability for long production runs.
Analyzing the architectural parameters of Projected Capacitive (PCAP) vs. Resistive Touch Screen Technologies to optimize your engineering choice.
| Feature Spec | Projected Capacitive (PCAP) Touch Panel | Resistive Touch Panel (4-wire / 5-wire) | Selection Criteria Recommendation |
|---|---|---|---|
| Operating Mechanism | Electrostatic field changes caused by human finger proximity (multi-touch up to 10 points). | Pressure-activated physical contact between micro-spaced conductive layers (single point touch). | Select PCAP for modern gesture-controlled interfaces; select Resistive for pressure-based inputs. |
| Optical Bonding | Highly recommended (OCA/LOCA full-lamination) to eliminate reflection and moisture build-up. | Typically air-bonded due to flexural requirements of top polyester film sheet layers. | Full optical lamination prevents internal condensation and enhances outdoor display readability. |
| Scratch & Chemical Resistance | Extremely high. Tempered cover glass (up to 7H Mohs hardness) resists acids, alkalis, and solvents. | Moderate. Outer PET sheet is scratch-susceptible and can be damaged by sharp industrial elements. | Select PCAP for high-wear public kiosks or sterile chemical environments (medical/laboratory). |
| Glove / Input Compatibility | Requires tuned IC controllers for thick leather/latex gloves. Won't respond to non-conductive styluses. | Responds to all styluses, gloves, fingernails, and tools because activation is strictly pressure-based. | Resistive panels are highly suitable for heavy-duty factory floors where operators wear insulated gloves. |
| Extreme Temperature Range | Operating: -20°C to +70°C. Storage: -30°C to +80°C (wide temp custom ICs available). | Operating: -30°C to +85°C. Storage: -40°C to +90°C (highly stable mechanical behavior). | Wide-temperature designs are ideal for remote petroleum fields, cold-chain transport, and outdoor charging hubs. |
How our custom engineering address specialized regulatory and design challenges across core commercial markets.
Medical environments demand liquid resistance and bio-compatibility. Our capacitive panels support high-concentration chemical wash-downs (e.g., IPA, bleach). Featuring AG (Anti-Glare) and AR (Anti-Reflective) coatings, our panels ensure optimal visibility under operating room lamps. We configure custom touch controller ICs to detect inputs from double-layered surgical latex gloves, meeting surgical standards.
Outdoor panels face extreme sunlight, UV exposure, and moisture ingress. Our outdoor capacitive panels utilize specialized UV-blocking film filters to prevent yellowing or delamination. Optical bonding techniques eliminate the internal air gap to prevent condensation, while 3-6mm custom cover glass provides high vandal resistance (IK10 rated) in public locations.
Heavy industrial systems require high noise immunity. Our 5-wire resistive and custom capacitive touch solutions feature shielding and optimized firmware configurations to prevent false triggers in electromagnetic fields near heavy motors or inductive welders. The physical architecture is tested for thermal shock stability to ensure reliable performance on active factory floors.
From prototype design to full mass production, we customize touch screen specifications to match your exact application requirements.
Strict adherence to international industrial manufacturing processes to guarantee consistent batch-to-batch quality.
Guangzhou Xiangrui Optoelectronics Technology Co., Ltd. complies with the ISO 9001:2015 Quality Management System and ISO 14001:2015 Environmental Management System standards. Our cleanrooms are monitored online for dust concentration, ESD protection, temperature, and relative humidity.
Every step of our process—from incoming material inspection (IQC), in-process inspection (IPQC), to final quality control (FQC) before packaging—undergoes rigorous automated optical checking (AOI) alongside dynamic testing. This ensures our touch panels meet strict quality criteria for linearity, response time, optical transmission, and environmental reliability.
