Engineered to operate seamlessly across high-altitude and humid tropical environments, serving Bogota, Medellin, and coastal logistics hubs.
Colombia’s unique geographic diversity poses direct engineering challenges for electronic Human-Machine Interfaces (HMIs). From the high altitude and lower barometric pressure of Bogotá D.C. (2,640m elevation) to the high humidity, temperature fluctuation, and salinity of coastal port cities like Barranquilla and Cartagena, standard touch panels often fail prematurely due to optical fogging, condensation, or air-gap compression.
At Guangzhou Xiangrui Optoelectronics Technology Co., Ltd., we customize our touch button sensors and resistive/capacitive overlays using advanced LOCA (Liquid Optically Clear Adhesive) Optical Bonding and custom ITO coating thickness. This prevents atmospheric moisture condensation inside the display layers, ensures robust resistance against salt spray in maritime terminals, and guarantees reliable operation of resistive screens in high-altitude packaging applications without false touch registrations.
Specially designed ventilation and air-gap equalization membranes for resistive touch panels deployed in Bogotá, ensuring sensor grids do not collapse under altitude shifts.
Capacitive touch controllers programmed with advanced water-rejection algorithms to prevent ghost touches caused by water droplets in high-humidity agricultural settings.
A globally recognized ISO 9001:2015 and ISO 14001:2015 certified manufacturer of high-performance custom touch panels.
Founded in 2010, our 3,000 square meter state-of-the-art facility integrates advanced research, development, and vertical production for resistive touch panels, projected capacitive (PCAP) touch sensors, custom cover glass printing, and high-precision module bonding. With class 100, class 1,000, and class 10,000 dust-free workshops, we regulate every stage of screen laminating and glass tempering to supply fault-tolerant displays for heavy-duty deployments.
By utilizing automated glass-cutting, high-precision chemical etching, and cleanroom vacuum thermal bonding, we consistently achieve an assembly yield rate that surpasses standard industrial thresholds, earning the trust of tier-1 industrial clients across more than 40 countries, including localized supply support for Colombia's emerging industrial zones.
Understanding the engineering details that differentiate high-grade touch systems from consumer screens.
Eliminates the air gap between the touch sensor and the LCD screen by applying optically clear liquid gel. This blocks dust infiltration, prevents internal fogging, enhances contrast ratio by 400%, and increases structural impact resistance to withstand vandal impacts in public spaces.
Available with AG (Anti-Glare) to diffuse light reflections in outdoor settings; AR (Anti-Reflective) film to maximize visibility under high ambient sunlight; and hydrophobic AF (Anti-Fingerprint) coating to reduce oil buildup and allow easy cleaning.
Equipped with customized controller ICs (EETI, Ilitek, and FocalTech chips) that are tuned to filter high-frequency electrical noise from high-voltage motors, power supplies, and inverters found in modern Colombian factories.

How our custom touch buttons and panels solve real-world problems in key regional industries.
In Colombia’s coffee roasting, sorting, and sugar refining factories, fine organic dust is common. We offer robust IP65-sealed, wide-temperature resistive touch interfaces that prevent airborne particles from entering behind the display bezel, ensuring uninterrupted operation in dust-heavy environments.
Serving clinics in Medellín and Bogotá, our capacitive touch controllers support surgical glove operations and are chemical-resistant, enabling sanitization with isopropyl alcohol and bleach without surface degradation.
For mass transport terminals (like TransMilenio stations), we deliver IK08 and IK10 vandal-proof cover glass layouts, featuring custom capacitive touch buttons that endure constant high-volume use and sudden physical impacts.
We recognize the logistical and regulatory framework required by the Colombian Ministry of Commerce, Industry and Tourism (MinCIT) and technical standards like RETIE (Reglamento Técnico de Instalaciones Eléctricas).
Every touch button component and screen module we ship into Colombia conforms with RoHS directives, CE testing, and FCC electromagnetic compliance. To facilitate seamless customs clearance at key sea entry ports including Barranquilla, Cartagena, and Buenaventura, we provide complete, structured HS Code declarations (typically under tariff heading 8471.60 / 8537.10) and robust dual-wall packaging to protect delicate optoelectronic modules from moisture during long ocean transit routes.
For high-priority industrial projects, we coordinate fast air freight delivery to El Dorado International Airport in Bogotá, backed by virtual 24-hour engineering alignment and technical support SLAs.

Expert technical answers to assist industrial engineers, procurement leads, and product designers.
High ambient humidity can introduce parasitic capacitance on the surface of PCAP panels, potentially causing "ghost touches." To prevent this, we configure our capacitive touch controllers (such as EETI and Ilitek) with advanced firmware algorithms that distinguish between a dynamic finger touch and static moisture patterns. Additionally, we recommend optical bonding to eliminate moisture condensation inside the air gap.
Traditional resistive touch panels rely on an air gap between two layers. At Bogotá’s elevation of 2,640 meters, lower atmospheric pressure can cause the air inside the gap to expand, pushing the layers outward or creating uneven surface tension that results in touch failure. We solve this by using custom pressure-equalization vents or true-flat projected capacitive (PCAP) glass designs, which do not rely on internal air gaps.
We offer three primary glass treatments: Anti-Glare (AG) chemical etching, which reduces specular reflection; Anti-Reflective (AR) physical vapor deposition coating, which minimizes surface reflections; and Anti-Fingerprint (AF) hydrophobic nano-coatings, which repel skin oils. For outdoor ticketing terminals, combining AR glass with optical bonding ensures high visibility under bright direct sunlight.
Yes, our capacitive touch controllers can be tuned to detect touches through latex, nitrile, and surgical gloves. For environments requiring heavy leather or thermal safety gloves, we recommend our specialized resistive touch panels, which register input from physical pressure rather than electrical capacitance.
For prototype designs, standard manufacturing and air freight to Bogotá take approximately 3 to 4 weeks. For bulk orders shipped by ocean to Barranquilla, Buenaventura, or Cartagena, lead times are typically 6 to 8 weeks. We provide detailed commercial invoices, packaging list details with proper HS code categorization, and certificates of origin to assist with import clearance and RETIE regulations.
