Founded in 2010 and located in Guangzhou, China, we are a high-technology enterprise dedicated to the research, development, custom engineering, and mass production of resistive touch panels, capacitive touch panels, cover glass, and complete module optical bonding. We specialize in robust customized designs for critical environments, serving global clients via professional OEM and ODM services.
Through active investment in advanced technology, our corporate operations have achieved ISO 9001:2015 Quality Management and ISO 14001:2015 Environmental Management certifications. Our high-durability displays are integrated daily into advanced industrial automation, high-precision medical machinery, IoT home appliances, smart home access panels, ruggedized outdoor kiosks, and palm-print recognition payment terminals.
The 12.1-inch display size has long been the global industrial standard due to its versatile aspect ratio (traditionally 4:3 with SVGA/XGA resolutions, and increasingly 16:10 in wide format). It provides the optimal balance of visibility and space-saving integration. However, not all 12.1-inch touchscreens are built equal. When procuring for high-reliability commercial, industrial, or medical operations, design engineers must navigate complex technical variables including sensor architectures, optical treatments, and driver IC tuning.
PCAP (Projected Capacitive) technology provides premium durability, 10-point multi-touch, and excellent optical clarity (>90% light transmission). Utilizing Glass-on-Glass (G+G) stackups, it resists scratching and chemical degradation. Resistive panels (such as 4-wire or 5-wire architectures) offer physical pressure activation, allowing seamless operability with heavy industrial gloves, stylus, or in environments heavily prone to liquid droplets and electrical EMI noise.
Standard air-bonding leaves an air gap between the touch layer and LCD, which causes reflections and condensation in changing climates. Xiangrui’s advanced optical bonding (OCR / LOCA) eliminates the internal air gap. This process improves sunlight readability by reducing reflections up to 70%, increases physical impact strength by up to 300% (IK08-IK10 compliance), and prevents dust or moisture ingress inside the display assembly.
We source industrial-grade controller ICs from leading silicon providers (EETI, Ilitek, and Microchip). These controllers are flashed with customized firmware to accommodate special requirements, including water rejection algorithms, glove touch support (up to 5mm thick leather/latex), and specific electromagnetic compatibility (EMC) parameters for medical or avionics applications.
Used heavily in factory automation systems, PLCs, and CNC machines. Under severe vibration, airborne particulates, and grease exposure, our IP65-rated 12.1" wide-temperature resistive touchscreens maintain error-free touch coordinates and resist wear from continuous mechanical pressure.
Integrated into anesthesia machines, ventilators, and clinical monitors. The capacitive touchscreen surfaces resist aggressive chemical disinfectants (IPA, bleach) and support single-touch or multi-touch input even when operators wear surgical latex gloves.
Our screens are designed for outdoor parking meters, ticket kiosks, and palm-print payment systems. They feature high scratch resistance (7H-9H hardness), vandal-proof cover glass, and high-brightness backlights for reliable outdoor operations.
Our OEM/ODM process provides engineers with tailored integration options. For marine and avionics systems, we supply sunlight-readable panels equipped with high-brightness backlights (up to 1,500 nits) and ultraviolet (UV) blocking films to prevent yellowing. For secure kiosk applications, we offer customized privacy filters integrated directly into the display stack-up during lamination.
All finished products undergo stringent performance validation, including temperature testing in thermal chambers, humidity tests, and electrostatic discharge (ESD) exposure limits to ensure survival in demanding industrial environments.
Development is focused on decreasing touch response latency to under 5 milliseconds. Active pen protocol compatibility (like USI or Microsoft Pen Protocol) is being integrated directly into our 12.1" PCAP sensor arrays, enabling high-precision coordinate input alongside multi-finger gesture recognition.
We are incorporating piezo-electric haptic actuators into custom touchscreen assemblies. This permits tactile feedback (simulating clicks or vibrations) when the operator touches an on-screen button, improving safety in critical automotive, aerospace, and medical monitoring systems.
Using Metal Mesh and Silver Nanowire (AgNW) technologies to replace brittle ITO (Indium Tin Oxide) sensors. This allows for lighter modules, higher transmission rates, and seamless compatibility with under-display fingerprint sensors or biometric optical readers.
Based in Guangzhou, China—the global hub for flat-panel displays—Xiangrui benefits from an integrated supply chain. We maintain direct, long-standing relationships with chemical glass manufacturers, ITO film coaters, driver IC suppliers, and LCD panel manufacturers, ensuring stable components and minimal lead times.
Our 3,000-square-meter facility houses modern cleanroom workshops (Class 100 to Class 10000). The assembly, optical bonding, and cover glass lamination processes are completed under controlled particle counts, maintaining high yield rates and clean optical displays. Our production capacity allows us to efficiently manage large-scale OEM runs while remaining flexible for custom, low-volume ODM projects.
Through robust logistics networks in Guangzhou, Shenzhen, and Hong Kong, we ship customized touch modules globally with secure packaging and complete customs clearance documentation.
To successfully integrate touchscreens into global industrial hardware, compliance with international regulatory frameworks is essential. At Guangzhou Xiangrui, we design and validate our touch modules to meet strict quality and environmental standards across target markets.
Our touchscreens are manufactured using RoHS-compliant and REACH-certified raw materials, ensuring chemical safety and environmentally-responsible disposal. Standard production builds conform to CE, FCC, and UL safety standards to simplify the certification process for your end products.
We provide localized technical assistance for hardware and software integration. Our engineering team assists with USB, I2C, and RS232 driver integration across major operating systems including Windows, Linux, Android, and RTOS, facilitating faster product development.
Industrial lifecycles typically span 5 to 10 years. We protect our customers from premature component obsolescence by offering backward-compatible touch controller firmware and form-fit-function mechanical consistency over the lifetime of your product lines.
