Explore our industrial-grade, wide-temperature resistive and capacitive sensor solutions
Founded in 2010 and strategically positioned in the industrial hub of Guangzhou, China, Guangzhou Xiangrui Optoelectronics Technology Co., Ltd. is a leading manufacturer dedicated to the research, development, production, and worldwide distribution of resistive touch panels, capacitive touch panels, cover glass, and complete module bonding products. Over the past decade, we have established ourselves as an industry leader in customized touch screen solutions, providing comprehensive OEM and ODM services for global partners.
Driven by our core philosophy of being "people-oriented, honest, pragmatic, innovative, and enterprising," we are committed to constant research and engineering advancement. By continually introducing new processes and new materials, our professional R&D team and highly skilled production staff ensure that we remain competitive in a rapidly changing market.
A look at the infrastructure that enables us to support global touch screen supply chains.
Key considerations for technical buyers and procurement departments looking to integrate industrial touch panels.
Global enterprises face unique challenges when procuring touch control interfaces. Whether integration is planned for sterile medical equipment, harsh industrial settings, smart home ecosystems, or public payment kiosks, a one-size-fits-all approach is insufficient. Industrial products demand reliable lifespans (typically 5 to 10 years), mechanical resistance against impacts, and stable performance under extreme thermal and environmental conditions.
At Guangzhou Xiangrui, we bridge the gap between design concepts and physical touch panels. Our engineering staff collaborates with global system integrators to define parameters such as cover glass thickness, surface treatments (AG/AR/AF), controller IC protocols (I2C, USB, RS232), and optical bonding layers to guarantee optimal readability and durability.
Additionally, we understand that supply chain stability is critical for long-term production. With ISO 9001 and ISO 14001 standard systems implemented across our manufacturing processes, we minimize yield variances and guarantee structured traceability from raw material entry to the shipping dock.
Understanding which sensor technology matches your application requirements.
Utilizes a sensor grid embedded in glass or film layers to detect changes in electrical capacitance caused by human touch. Supports multi-touch features, boasts high transparency, and resists scratches, making it ideal for modern consumer electronics and high-use public kiosks.
Relies on physical pressure to join conductive layers. Because it does not require electrical conductive contact, it operates seamlessly when using gloved fingers, plastic styluses, or cards. It is highly resistant to EMI noise and liquids, making it perfect for manufacturing floors.
We fill the air gap between the touch sensor and the LCD panel using optical-grade resins (LOCA/OCA). This eliminates internal light reflection, boosts sunlight readability, improves impact resistance, and prevents condensation or dust infiltration behind the screen.
| Feature Parameter | Resistive Touch Modules | Projective Capacitive (PCAP) Modules | Guangzhou Xiangrui Solution Advantage |
|---|---|---|---|
| Operating Input | Glove, stylus, finger, any solid object | Bare finger, conductive stylus, thin gloves | Customized controller tuning for multi-input styles |
| Optical Clarity | ~75% - 85% light transmission | ~88% - 92% light transmission | Optical bonding increases clarity by up to 98% |
| Environmental Resistance | Resistant to liquids, dust, and EMI | Needs shield adjustments for wet/conductive environments | IP65-rated front panel seals with custom cover glass options |
| Scratch Hardness | 3H (PET polyester outer sheet) | 6H - 7H (Standard Cover Glass) | Chemical tempering upgrades to 9H cover glass protection |
| Multi-touch Support | Single-touch only (Standard) | Multi-touch (up to 10 points supported) | Controller options for custom gesture recognition protocols |

Supported by our in-house engineering lab, we consistently secure utility and invention patents. We were recognized as an official Guangdong High-Tech Enterprise in 2022.
Staying ahead of industry trends to ensure your products remain competitive and relevant.
Demand for compact capacitive interfaces is surging in home automation, appliances, and HVAC controls. Our slim, custom-printed cover glass solutions offer seamless integration into curved panels and textured glass structures.
Medical touch screens must support surgical gloves, endure sanitization chemicals, and maintain continuous, error-free operation. We configure customized touch sensitivity profiles that reject false inputs from fluids and gels.
Devices like payment stations, parking meters, and outdoor handhelds demand high UV resistance and wide operating temperature ranges. Our optical bonding solutions utilize UV-absorbing adhesives that protect displays from yellowing and thermal degradation under direct sunlight.
