Explore our top-tier capacitive and resistive screen models engineered for extreme environments, commercial kiosks, and industrial automation.
The global market for interactive touch screens has transitioned from simple consumer electronics integration to complex, heavy-duty industrial and public-access operations. Driven by the expansion of the Internet of Things (IoT), Industry 4.0, and interactive point-of-sale terminal displays, standard mechanical buttons are rapidly being replaced by capacitive and resistive touch panel matrices.
In modern manufacturing hubs and medical diagnostics, interactive screens require advanced glass tempering, custom sizes (from small 1.54-inch displays for wearables to large-format 15-inch modules for terminal controls), and exceptional touch precision. Industrial settings present challenges such as extreme temperature fluctuations, high humidity, chemicals, and electromagnetic interference. As a result, standard products often fall short, making high-quality, customized OEM and ODM services essential for international supply chains.
Guangzhou Xiangrui Optoelectronics Technology Co., Ltd. is positioned at the intersection of this technology curve. We design, prototype, and manufacture custom resistive and capacitive panels that comply with ISO standards. This ensures high optical performance, robust touch sensitivity, and durability across diverse industrial applications.
Founded in 2010 and located in Guangzhou, China, Guangzhou Xiangrui Optoelectronics Technology Co., Ltd. is a company dedicated to the research and development, production, sales, and service of resistive touch panels, capacitive touch panels, cover glass, and module bonding products. We provide customized production of various touch screens, as well as comprehensive OEM and ODM services.
Our company operates on the fundamental principle of being "people-oriented, honest, pragmatic, innovative, and enterprising." This philosophy unites our teams to maintain market competitiveness and drive stable development. Since our establishment, we have focused on the research, application, and development of new products, processes, and materials. Our professional R&D team, coupled with our production experience and service, ensures our clients receive reliable optoelectronic products tailored to their application requirements.
Our manufacturing systems are highly standardized. The company has obtained the prestigious ISO 9001 and ISO 14001 certificates, indicating that all processes—from raw material inspection to final product assembly and cleanroom manufacturing—conform to international quality and environmental management standards.
Understanding the fundamental differences in touch screen architecture allows industrial engineers to specify the correct display model for their operating environments.
Projected Capacitive technology utilizes an Indium Tin Oxide (ITO) sensor grid layer laminated behind a protective cover glass. When a finger approaches, it creates a capacitive coupling that alters the electrostatic field. This supports multi-touch, high optical clarity (exceeding 85% light transmission), and compatibility with tempered glass overlays for vandal protection.
Resistive touch screens consist of two flexible conductive layers separated by small spacer dots. Pressing the screen surface forces these layers to make electrical contact, registering a touch. Resistive panels are pressure-activated, meaning they can be operated with fingernails, heavy work gloves, or styluses. They are cost-effective and highly resistant to EMI and water droplets.
Optical bonding involves applying a liquid gel (OCR) or dry film (OCA) adhesive between the touch glass layer and the underlying LCD panel. This process eliminates the internal air gap, reducing ambient light reflection by up to 90%, preventing condensation in high-humidity environments, and enhancing the mechanical durability of the display.
To ensure dust-free laminations and prevent optical defects, our factory features dedicated cleanroom workshops structured by cleanliness requirements:
Our plant occupies 3,000 square meters, utilizing automated precision laminators, FPC bonding machinery, laser etching tools, and environment-controlled curing systems to guarantee consistent panel output.
Touch screen assemblies serve as the primary human-machine interface (HMI) across various technical fields. We design customized structures to meet the specific requirements of each sector:
Industrial automation PCs require IP65 ingress protection, chemical resistance, and support for gloved operation. Our wide-temperature industrial-grade capacitive touch panels deliver consistent performance, even in heavy dust or high vibration environments.
Medical monitors require anti-bacterial cover glass, compatibility with clinical cleaners, and precise touch response. We utilize optically clear adhesives (OCA/OCR) and custom cover glass to ensure clarity and reliability under harsh hospital lighting.
Domestic automation and kitchen appliances benefit from sleek glass-front interfaces. Our capacitive touch buttons and round cover glass designs feature custom silk-screen printing to match modern home aesthetics.
Atmospheric conditions demand UV filters, high-brightness readability, and impact resistance (IK08+ rating). Our optical bonding process prevents fogging, while special chemical treatments protect the screen from direct solar heat.
To maintain reliable performance in demanding environments, Guangzhou Xiangrui Optoelectronics applies strict quality control at every phase of the manufacturing process:
Our dedication to quality is supported by our ISO 9001:2015 Quality Management and ISO 14001:2015 Environmental Management certifications.
