Explore our engineering capabilities across varied sizing, custom cover glasses, and rugged bonding configurations.
Founded in 2010 in Guangzhou, China, we are an integrated high-tech enterprise specializing in the design, engineering, and manufacturing of premium industrial-grade resistive and capacitive touch panels. With a decade of technical refinement, our core competencies span the manufacturing of cover glass, sensor patterning, micro-soldering of controller circuits, and optical bonding services.
We provide comprehensive OEM and ODM services, catering custom touchscreen geometries to system integrators globally. Our management systems are audited and certified to ISO 9001 (Quality Management) and ISO 14001 (Environmental Management). Whether optimizing for extreme operating temperatures, low-power medical devices, or vandal-resistant kiosks, we execute tailormade solutions built to perform in the field.
Our 10,000 square meter modern facility leverages cleanroom production lines and highly automated optical inspection matrices to eliminate contaminants.
Our facility manages particulate control to the highest standards. Laminar flow stations guarantee that the critical gap between LCD screens and touch sensors is bonded with zero dust inclusion. This level of environmental control is essential for optical bonding technologies (using liquid optoelectronically clear adhesives, or LOCA) to maintain optimal transmission values and prevent visual distortion.
An architect's breakdown of Projective Capacitive (PCAP) and Resistive touch technologies, surface treatments, and stack integrations.
Engineered with double-sided ITO sensor layers for high-sensitivity multi-touch. Integrates industrial ICs (EETI, ILITEK, focalTech) to sustain operation through thick protective gloves, water droplets, and high EMI exposure.
Utilizes physical pressure-based actuation, making it completely immune to non-conductive interference. Optimized for heavy mechanical operations where stylus inputs or heavy insulated gloves are standard.
Eliminates the internal air gap between the touch layer and the LCD panel. Drastically improves sunlight readability, drop test resilience, and prevents condensation or fogging under high humidity.
The structural composition of a touch panel dictates its longevity and suitability for specific environments. We offer several design configurations:
Tailoring touch parameters to meet the regulatory, environmental, and operation challenges of diverse verticals.
Industrial environments present harsh conditions—heavy vibrations, dust, oils, and strong electrical currents. Our touch screens feature IP65-sealed front panels and high-noise immunity controllers. This prevents false touch triggers caused by nearby high-voltage machinery or liquid sprays.
Medical displays require cleanability. Our cover plates support continuous sanitization using harsh agents like isopropyl alcohol or bleach. In addition, the controller firmware is calibrated to register touches from sterile latex or nitrile surgical gloves.
For public interfaces and automated ticketing systems, we use tempered safety glass with chemically strengthened profiles. Anti-Glare (AG), Anti-Reflective (AR), and Anti-Fingerprint (AF) coatings improve visual readability in high-ambient glare settings.
Designed with UV block-out filters to prevent optical yellowing of the OCA and sensor layers. The wide temperature operations capability (-30°C to +85°C) prevents the screen from entering thermal lock under direct solar load.
As human-machine interaction evolves, touch screen technology is advancing from standard planar inputs to complex sensory systems. Our research and development focuses on the integration of silver nanowires (AgNW) and metal mesh sensors to support ultra-thin, flexible, and curved displays.
Additionally, we are pioneering the integration of haptic feedback systems using localized piezoelectric actuators. This simulates physical button presses on flat cover glass, enhancing tactile verification in safety-critical applications. By optimizing index-matching coatings, we are also enhancing readability under extreme direct solar radiation, achieving reflection percentages of less than 1.5%.
Key checkpoints for procurement managers, hardware engineers, and quality assurance leads during component qualification.
Industrial settings are full of RF noise. We ensure our touch screens meet FCC Class B and CE norms. The firmware features dynamic frequency hopping to automatically detect and avoid noise bands, ensuring reliable touch input.
For high-risk environments, we provide chemical strengthening processes (soda-lime or aluminosilicate glass) with thicknesses up to 10mm. This configuration passes IK10 ball drop impact testing for public systems.
Guangzhou Xiangrui Optoelectronics Technology Co., Ltd. secures raw material supply chains by partnering with global manufacturers of glass sheets, optical adhesives, and IC controllers. Our localized Field Application Engineering (FAE) program helps clients integrate and calibrate touch systems with their masterboards. We guarantee a minimum 7-year product availability lifecycle, avoiding redesign costs for industrial system developers.
Technical answers to common design and purchasing questions for engineers and purchasing managers.
Optical bonding uses LOCA or OCR adhesives to fill the internal air gap between the touch sensor and the display module. This eliminates reflection-prone surfaces, improving outdoor contrast by up to 400%. It also keeps out moisture, dust, and condensation, and enhances resistance to mechanical shocks.
Our capacitive controllers use custom firmware algorithms that distinguish between a concentrated touch finger and a flat water film. This allows the system to remain responsive and prevent false touches when wet, which is key for outdoor kiosks and medical equipment.
We offer customization for cover glass thickness (0.5mm to 10mm), shape cutting, 2.5D chamfered edges, customized printing (logo, buttons, border colors), and functional surface treatments like anti-glare, anti-reflection, and anti-fingerprint coatings.
Yes, all products comply with RoHS and REACH standards. Our factory processes follow ISO 9001 and ISO 14001 guidelines, ensuring traceablity and consistent quality control for each production batch.
