Inquire NowSão Tomé and Príncipe is undergoing a structural digital transition. With investments rising in port logistics, automated meteorology, marine operations, and expanding hospitality networks, the need for robust Human-Machine Interfaces (HMIs) has never been higher. Unlike standard electronics, devices installed in STP face aggressive environmental factors: continuous high relative humidity (often exceeding 80%), intense UV exposure, and salt mist from the surrounding Gulf of Guinea.
Guangzhou Xiangrui Optoelectronics Technology Co., Ltd. addresses these operational obstacles. We manufacture and custom-tune capacitive touch panels to prevent water-droplet misoperation, support gloved operation in industrial fisheries, and provide exceptional legibility under direct sunlight. Our products act as the key bridge allowing local enterprises to deploy stable interactive hardware without fear of premature degradation from environmental corrosion.
Understanding the engineering parameters required to survive extreme maritime conditions and intense tropical UV exposure.
By utilising Glass-on-Glass architecture and Optically Clear Adhesive (OCA) full bonding, we eliminate the air gap between the LCD and touch sensor. This completely prevents moisture condensation, dust accumulation, and internal fogging under high humidity.
Equipped with industrial controller chipsets from ILITEK, EETI, and Cypress, our panels maintain precise performance even when the screen is wet. The firmware filters out electrical noise generated by generators, maritime power lines, or wireless antennas.
For outdoor kiosks and vessel controls in STP, we apply specialized Anti-Glare (AG), Anti-Reflective (AR), and UV-cut film coatings. This preserves screen readability under intense sunlight and prevents polarization degradation over long exposures.
Founded in 2010 in Guangzhou, China, we are an industry leader specializing in the research, development, and high-precision production of custom resistive and capacitive touch screens, cover glass assemblies, and complex optical bonding solutions.
Spanning a facility of 3,000 square meters, we host specialized cleanrooms spanning class 100, 1,000, and 10,000 standards to ensure absolute particulate control. Our operation is certified under ISO 9001 and ISO 14001, proving our dedication to consistent quality and strict ecological responsibility.

From CAD layout design to marine-ready functional validation, we follow a rigorous OEM/ODM process.
Clients submit dimensional, touch IC, interface (USB/I2C/RS232), and environmental requirements. Our R&D department creates CAD drawings and mockups within 48 hours.
Lamination occurs in Class 100 dust-free workshops. We customize cover glass parameters: Chemically tempered, thickness (0.7mm to 10mm), anti-shatter film, and custom colors/logos.
Every production batch undergoes climate chamber testing (ranging from -40°C to +85°C), 95% humidity simulation, salt mist spray testing, ESD resistance, and drop-ball impact validations.
Guangzhou Xiangrui Optoelectronics operates under highly standardized frameworks to manage and offset risks associated with complex optoelectronic manufacturing. From raw-material inspection (IQC) to production process control (IPQC) and final quality control (FQC), no panel leaves our facility unchecked.
We have earned numerous utility model patents and invention patents, being awarded the prestigious title of "Guangdong Province High-Tech Enterprise" in 2022. This demonstrates our capacity to develop next-generation touch solutions capable of integrating with marine radar equipment, agricultural IoT devices, and specialized medical diagnostic terminals.

Request QuoteWe understand that international sourcing into West Africa requires careful logistical oversight. Guangzhou Xiangrui provides customized export packaging (vacuum-sealed anti-static bags, thick high-density EPE foam cradles, and heavy-duty outer crates) to withstand ocean transit to the Port of São Tomé or air freight into São Tomé International Airport. We supply comprehensive documentation including certificate of origin, RoHS compliance reporting, and custom HS code declarations to ensure zero delays at customs checkpoints.

Glass-on-Glass (G+G) features a glass cover and a glass sensor. Unlike polyester films (G+F), glass does not expand or contract under intense heat and moisture. G+G displays resist chemical erosion from ocean spray (salinity) and maintain optical transparency without yellowing or bubbling under long-term solar UV exposure, which is critical in STP's tropical marine environment.
We use high-performance touch ICs (EETI or ILITEK) with advanced mutual capacitance configurations. The firmware is specifically written to recognize the difference between a conductive human touch and static water droplets, mist, or rain on the cover lens. This prevents "ghost touches" or total lockups on agricultural or marine boat terminals.
We provide comprehensive design support, including cover glass size, thickness (ranging from 0.7mm to custom thick vandal-resistant dimensions), custom color borders, and company branding. We also offer specialty coatings like Anti-Glare (AG) to reduce reflections outdoors, Anti-Reflective (AR) to maximize transparency, and Anti-Fingerprint (AF) coatings. Electronic interfaces (I2C, USB, RS232) can be designed to match your host motherboard.
We provide full documentation proving compliance with ISO 9001 and ISO 14001 guidelines. Our panels comply with RoHS and CE standards. We draft all required international trade declarations, shipping lists, and bill of lading documents to make port clearance as smooth as possible.
Yes. While capacitive touch is the standard for multi-touch performance and optical clarity, we also produce high-quality resistive panels (such as 12.1" and 15.6" options with IP65-rated bezels) suited for industrial machinery where workers must use gloves or plastic styling tools in dust-rich processing areas.
We source raw components with long life-cycle guarantees from top international vendors. If a specific IC chip or glass component undergoes generational changes, we provide notice at least one year in advance and offer pin-to-pin compatible replacement models, ensuring our partners in São Tomé and Príncipe have stable support for years to come.
