Explore our diverse lineup of custom optical and frame-bonded touch panels engineered to excel across demanding conditions and extreme temperatures.
The 19-inch touch screen has emerged as a global HMI (Human-Machine Interface) benchmark size, striking a perfect balance between functional interface layout and compact physical footprints. Primarily configured in 5:4 square display orientations or modern 16:9 and 16:10 wide-screen formats, this dimension is uniquely positioned within heavy industrial instrumentation, commercial kiosks, healthcare monitors, point-of-sale systems, and interactive marine consoles.
As industrial sectors execute massive moves toward Automation 4.0, the requirement for robust input devices has shifted from basic push-buttons to advanced touch screens. In critical environments, a standard commercial tablet will fail due to high electrical noises, temperature fluctuations, and exposure to liquids or physical shocks. This is where customized 19-inch panels engineered with high-noise immunity controllers, thick safety glass, and custom anti-reflective coatings deliver stable performance.
Modern commercial and industrial interfaces favor PCAP systems for their multi-touch input capability (up to 10 points), crystal clear transparency, and superior mechanical durability. By utilizing localized electric fields, they register touches through cover plates exceeding 8mm in thickness.
In heavy manufacturing zones, marine vessels, or cleanroom labs where operators wear thick rubber or chemical-resistant gloves, specialized analog resistive screens remain indispensable. They operate flawlessly under pressure, unaffected by surface contaminants, liquids, or electromagnetic interference.
Founded in 2010 and based in Guangzhou, China, we are a premier high-tech enterprise dedicated to the research, development, custom engineering, and mass production of advanced resistive touch panels, capacitive touch panels, customized cover glass, and complete optical/frame bonding modules.
Our core mission is centered on high quality standards, persistent innovation, and custom tailoring capabilities. We hold certifications for ISO 9001:2015 and ISO 14001:2015, which form the bedrock of our quality system. In 2022, we were officially recognized as a "High-Tech Enterprise" in Guangdong Province, testament to our R&D prowess and growing collection of utility patents.
Whether you require deep customization (OEM/ODM), special optical coatings, or wide temperature limits, our dedicated engineers support your project from initial CAD design to production stages.
To prevent dust contamination during the laminating, printing, and bonding processes, our facility is equipped with specialized Class 100, Class 1,000, and Class 10,000 cleanrooms. This environment keeps particle counts under control, ensuring visual clarity and zero defects for high-resolution 19-inch touch modules.
Procuring custom 19-inch touch modules requires consideration of the stack-up layers, optical bonding, sensor configuration, and controller IC firmware. A properly designed screen must balance ruggedization against responsiveness.
We offer both LOCA (Liquid Optical Clear Adhesive) and OCA film optical bonding. Optical bonding fills the air gap between the display panel and the touch sensor, eliminating internal reflections, boosting ambient sunlight readability by up to 400%, and preventing internal fogging under high humidity.
Enhance user interface visibility with specialized chemistry: AG (Anti-Glare) to diffuse reflections, AR (Anti-Reflective) coatings to minimize reflectivity under direct sunlight, and AF (Anti-Fingerprint/Oleophobic) to repel oils and optimize smooth swiping gestures.
We work with industry-standard IC developers including EETI, Ilitek, and Goodix. Our engineers calibrate touch sensitivity to enable seamless operation through heavy multi-layered work gloves, thick protective cover glass (up to 10mm), or in environments prone to liquid spray.
Producing specialized, ruggedized optoelectronic systems requires a strong local supply chain. Located in Guangzhou, the industrial heart of Southern China, our factory leverages a highly optimized supply chain network. We source high-grade raw glass, specialized ITO sensors, flexible print circuits (FPC), and advanced controller ICs locally at competitive costs.
Additionally, our semi-automated assembly line, in-house screen printing, cleanrooms, and testing facilities reduce processing times. We can prototype custom 19-inch designs in 2 to 3 weeks, compared to industry lead times that often exceed 6 weeks.
Our custom 19-inch touch screen modules are deployed across diverse industries globally:
Guangzhou Xiangrui Optoelectronics adheres to highly standardized manufacturing procedures. Our quality control system is active at every step: from raw material inspection (IQC) to cleanroom processing, sensor integration, lamination, and final functionality testing.
Our manufacturing workflow is certified to ISO 9001 and ISO 14001, verifying that both our product quality control and environmental footprint meet strict international standards.
To ensure long-term reliability, our 19-inch touch modules undergo thermal cycle testing (-40°C to +85°C), high-humidity aging (85% RH at 60°C), and electrostatic discharge (ESD) testing.
