Explore our highly-durable resistive and capacitive touchscreen solutions, manufactured to strict ISO certifications with customizable glass options.
Founded in 2010, Guangzhou Xiangrui Optoelectronics Technology Co., Ltd. has developed into a leading global pioneer in custom touch panel engineering. Based in Guangzhou, China, our company integrates deep material science research, hardware development, state-of-the-art production processes, and end-to-end quality assurance systems.
Our core capabilities center on custom touch screen development, covering resistive touch panels, projective capacitive (PCAP) touch screens, custom cover glass designs, and advanced optical module bonding. Guided by an engineering-first culture, we serve as a vital OEM and ODM partner for enterprises worldwide seeking highly customized human-machine interfaces (HMIs).
We operate from an ISO 9001 and ISO 14001 certified campus spanning a total facility footprint of approximately 10,000 square meters, featuring dedicated cleanroom manufacturing environments designed to limit contamination to negligible metrics.
Engineered for low-particle optical lamination and long product lifecycles in critical operating parameters.
Our main factory building houses over 3,000 square meters of specialized assembly zones. These are strategically divided into Class 100, Class 1,000, and Class 10,000 cleanroom workshops, meeting the dust-free environmental standards required for optical lamination, bonding, and defect-free ITO sensor production.
Navigating the complex technical requirements for HMI hardware in mission-critical applications.
Procurement specifications for outdoor and heavy industrial usage demand strict environmental resistance. Typical requirements include a wide operating temperature range (-30°C to +85°C) and resistance to UV degradation, thermal shock, moisture, dust ingress (IP65, IP67, or IP68), and mechanical impacts (IK08 to IK10 ratings).
In automation, medical engineering, and military deployment, electromagnetic interference (EMI) can trigger false touch inputs. Procurement engineers look for specialized sensor designs and shielding materials that comply with strict EMC regulations (such as IEC 60601-1-2 for medical devices).
Industrial designs typically require long product availability cycles (often 7 to 10+ years). Procurement teams require guarantees of component longevity, strict Change Control Processes (PCN), and reliable End-Of-Life (EOL) support to protect their engineering and testing investments.
How Guangzhou Xiangrui Optoelectronics addresses specialized touch challenges across key industrial sectors.
Medical HMIs require high precision, glove touch capability (even with thick surgical gloves), and resistance to biological fluids and harsh chemical cleaners.
Machinery environments subject equipment to vibration, grease, high humidity, and physical impacts. Our designs prioritize mechanical ruggedness and noise immunity.
Public installations experience constant usage and potential vandalism. The primary design goals here are wear resistance, readability, and multi-touch performance.
Modern smart appliances and high-end home control units rely on sleek, curved surfaces, dead-front optics, and fast, low-latency responsiveness.
Advancing human-machine interfaces through continuous material science and controller innovations.
We specialize in optical bonding using liquid optical clear adhesive (LOCA) or dry sheet adhesive (OCA). This method eliminates the air gap between the touch sensor and the LCD, reducing internal light reflections by up to 90%, improving contrast ratio, and eliminating internal condensation. Advanced surface treatments are standard, ensuring high visibility under bright ambient light.
Transitioning to alternative conductive layers, such as Metal Mesh or Silver Nanowires (AgNW). These materials provide lower sheet resistance, support curved and flexible overlay structures, and offer higher mechanical flex life for next-generation smart surfaces.
Integrating micro-actuators directly into the touch panel overlay stack-up to deliver localized physical click sensations to users. This technology is paired with on-board edge controllers that run filtering algorithms to eliminate invalid touch signals from water splashes or vibration.
Guangzhou Xiangrui Optoelectronics Technology Co., Ltd. operates with a core philosophy: reputation first, customer satisfaction, stable quality, on-time delivery, and long-term partnership. We maintain strategic relationships with component suppliers to ensure reliable, long-term support for our products.
To support international system integrators, we provide products that comply with RoHS, REACH, CE, and FCC standards. Our touch panel overlays are designed and certified to meet the technical standards of global markets, ensuring easy integration into your final products.
