Highly ruggedized touch systems compatible with embedded Linux architectures (Debian, Yocto, Ubuntu, Android) for industrial, medical, and outdoor setups.
Founded in 2010 and based in Guangzhou, China, Guangzhou Xiangrui Optoelectronics Technology Co., Ltd. has established itself as an authoritative leader in the research, development, and high-volume manufacture of capacitive touch panels, resistive touch panels, cover glass customizations, and complete display module bonding integrations.
Through our dedicated ISO 9001 and ISO 14001 certified manufacturing facilities, we deliver high-reliability OEM/ODM touch screen configurations that seamlessly interface with microcontrollers and single board computers running various kernel distributions of the Linux Operating System.
Whether for high-precision surgical instruments, heavy industrial factory automation, high-traffic retail systems, or marine navigation consoles, we tailor panel shapes, surface treatments (AG, AR, AF), shielding layers, and driver controllers to meet strict field performance metrics.
Integrating Touch controller ICs into standard Linux systems requires specialized kernel module implementation, signal noise isolation, and hardware matching.
We supply fully-compliant touch controllers supporting interfaces such as I2C (Inter-Integrated Circuit), USB, and SPI. Our systems integrate cleanly with standard Linux kernel modules like evdev, tslib, and modern graphical servers run by libinput, ensuring smooth pointer tracking, gesture recognition, and low-latency interaction.
Industrial settings pose heavy electromagnetic interference (EMI). Our engineering teams utilize high-end controller chips from Ilitek, EETI, Goodix, and FocalTech, configured with hardware-level digital filters, active shield configurations, and physical grounding trace layers to maintain touch accuracy under high-voltage ambient fields.
We provide both Frame Fitting (Air Bonding) and Optical Bonding (LOCA/OCA). Optical bonding removes the air gap between the display panel and the cover glass, eliminating internal light reflection, increasing outdoor contrast ratios up to 300%, and preventing condensation or moisture intrusion under extreme environments.
Our commitment to precision engineering requires strict control over particle contamination. To support this, our facility employs dedicated cleanroom layers configured for distinct stages of processing:
Guangzhou Xiangrui Optoelectronics is a certified high-tech enterprise of Guangdong Province (awarded in 2022). Our products pass ISO 9001 quality management standards and ISO 14001 environmental frameworks, guaranteeing robust longevity in global field environments.
We work closely with global design engineers to align custom hardware with software-defined requirements. Our core design competencies include:
Connecting system-level design requirements with optimized components for standard hardware platforms.
Providing multi-touch capacitive assemblies fitted with heavy shielding layers to withstand factory vibrations, voltage surges, and electromagnetic fields near heavy motors.
Supporting chemical resistance against aggressive disinfectants (alcohol, IPAs) and precise multi-touch accuracy when operated with latex or sterile surgical gloves.
Integrating low-profile capacitive interfaces, custom capacitive buttons, and optical lamination for clean aesthetics and reliable integration into modern smart building systems.
Using high-brightness displays with full optical bonding, UV protective filters, and IP65 dust/waterproof ingress protection ratings for continuous public use.
Navigating the dynamics of contemporary device lifecycles requires a reliable manufacturing partner. Our facilities in Guangzhou prioritize supply chain stability and process traceability:
By focusing on customer satisfaction, structured deadlines, and mutual growth, we maintain long-term partnerships with leading global enterprises and local system integrators.

As embedded devices evolve, we continuously align our manufacturing processes with the following industry developments.
We are developing touch surfaces with integrated tactile vibration actuators. This provides users with direct, localized physical validation of inputs on screen surfaces, which is particularly beneficial in high-vibration aerospace or industrial workspaces.
Transitioning from traditional flat panel geometries, we offer curved (2.5D and 3D) chemical-tempered cover glass lamination. This allows screens to conform to ergonomic console designs for vehicle dashboards and medical device enclosures.
By implementing sleep-to-wake hardware routines directly inside custom microcontrollers, we support energy-efficient operations. Devices remain in sleep states until dynamic proximity or capacitance wakes the underlying system.
As a global OEM partner, Guangzhou Xiangrui Optoelectronics ensures all products comply with international certification benchmarks and localization requirements:
