High-performance custom panels and assemblies built to withstand industrial-grade noise, extreme temperatures, and continuous usage.
Projected Capacitive (PCAP) and Resistive touch technologies are at the heart of human-machine interaction. While standard consumer displays require simple glass setups, industrial and professional environments demand robust mechanical construction, advanced optical treatments, and high electromagnetic compatibility (EMC).
To achieve multi-touch performance in environments exposed to moisture, heavy electromagnetic interference (EMI), or high temperatures, the engineering integration between the sensor pattern, the controller firmware, and the mechanical cover lens must be perfectly aligned. Using top-tier controller ICs from industry leaders (such as EETI, Ilitek, and Goodix), our engineering teams develop custom firmware matrices that allow water-rejection, glove-touch capabilities, and multi-touch recognition of up to 10 points simultaneously.
Moreover, optical bonding (LOCA/OCA) is utilized to eliminate the internal reflection layer between the touch sensor and the LCD. This enhances readability under direct sunlight, protects the display from internal condensation, and significantly increases impact resistance to meet stringent IK ratings (IK08 to IK10).
Founded in 2010 and strategically based in the industrial manufacturing hub of Guangzhou, China, we are a leading specialist in the design, research, development, and vertical manufacture of projected capacitive touch panels, resistive touch panels, cover glass, and full module optical bonding. We cater to high-reliability applications, providing fully tailored OEM and ODM services. Our quality management system and environmental practices are fully certified under ISO 9001 and ISO 14001.
Spanning an advanced production area of 3,000 square meters, our facility integrates cleanroom manufacturing environments ranging from Class 100 to Class 10,000. This ensures dust-free production essential for bubble-free optical bonding and sensor fabrication. With over 30 utility patents and a dedicated engineering team, we assist global clients from design prototype phase to mass manufacturing.
Unparalleled speed-to-market, raw material accessibility, and cost efficiencies managed by advanced engineering systems.
Located in the heart of Southern China's display cluster, we source raw ITO films, specialized glass substrates (such as Corning Gorilla Glass, AGC Dragontrail), and controller chipsets directly from primary sources, reducing overall material lead times.
China's highly optimized tooling and mechanical prototype systems allow for rapid sensor patterning modifications. Low NRE (Non-Recurring Engineering) costs and scalability let us support small production batches and high-volume rollouts.
From initial customer mechanical drawing (CAD) step-files to first prototype optical bonding evaluation samples, we offer quick turnaround times (within 2-3 weeks), keeping global project deadlines ahead of schedule.
When sourcing touch sensors from an OEM factory, procurement divisions within medical, aerospace, and kiosk industries prioritize long-term component availability, stable material supplies, and traceability.
We offer detailed product lifecycle management (PCN/EOL processes), guaranteeing sensor model support for at least 7 to 10 years, which is critical for long-lifecycle medical diagnostics and industrial control platforms. Furthermore, we maintain complete manufacturing logs for each batch (traceable by barcode from raw glass supplier to finished, bonded modules).
Seamless overseas communication coupled with engineering certifications for global deployment.
Our touch panel components are designed to meet RoHS, REACH, CE, FCC, and UL safety standards, allowing smooth integration into devices bound for North American and European markets.
We bridge timezone gaps with dedicated application engineers fluent in English, offering remote assistance for software debugging, driver integration, and chip tuning (EETI/Ilitek toolsets).
Through partnerships with global logistics hubs, we provide customized packaging to prevent static discharge and moisture damage during sea, air, or rail transport.
Engineered to perform in harsh, real-world operating environments.
Wide-temperature touch panels designed for factory floor controllers. Our screens support thick glove operation and reject electromagnetic noise generated by heavy industrial machinery, ensuring zero accidental touches.
Ensuring compliance with medical sanitation standards, our flat-surface touch modules resist chemicals, saline exposure, and cleaning solutions, while supporting precision latex glove control.
Using specialized cover glass coatings (Anti-Glare, Anti-Reflective, Anti-Fingerprint) and full UV-blocking optical adhesives, our touch displays prevent sun glare, moisture condensation, and LCD damage from UV exposure.
Custom cover lenses with custom shapes, colored bezels, and complex cutouts designed to seamlessly blend into home automation networks, kitchen environments, and smart appliances.
Custom touch panels with integrated palm print scanning window geometries and high scratch-resistant cover glass, built to handle continuous public use in modern transit and banking terminals.
The technological shifts defining the next generation of touch surfaces.
Modern HMIs are moving away from simple audio cues towards physical haptic responses, utilizing localized actuators to simulate tactile clicks on touch displays.
Flexible plastic substrates are replacing rigid glass, enabling curved designs for automotive consoles, modern smart home controls, and ergonomic industrial cockpits.
Display, touch panel, and single-board computer (SBC) architectures are merging into singular mechanical sub-assemblies, optimizing assembly times for OEMs.
Insights into multi-touch engineering, customized options, and ordering processes.
OCA (Optically Clear Adhesive) uses a dry film adhesive sheet pre-cut to the display size, ideal for small-to-medium panels. LOCA (Liquid Optically Clear Adhesive) is a liquid-based resin cured under UV light, preferred for large displays, curved interfaces, and designs with high structural tolerances. Both eliminate internal reflections, improve outdoor readability, and boost overall impact resistance.
Yes. Our engineering team customizes the drive-and-sense frequency configuration inside the touch controller (e.g., EETI/Ilitek). By boosting the sensor sensitivity (gain parameters) and adjusting signal-to-noise ratio (SNR) thresholds, we support multi-touch operation with latex, nitrile, leather, or insulated winter work gloves.
We provide three major surface treatments: Anti-Glare (AG), which diffuses light reflections; Anti-Reflective (AR), which uses optical thin-film interference to reduce reflectance below 1%; and Anti-Fingerprint/Anti-Smudge (AF), which provides a hydrophobic/oleophobic layer to make cleanings easier.
Our operations are certified under ISO 9001 and ISO 14001. We use cleanrooms rated from Class 100 to Class 10,000, and perform automated optical inspections (AOI), environmental thermal chamber testing (-40°C to +85°C), and drop testing to guarantee strict compliance with industry specifications before shipping.
MOQ varies depending on size, starting from 100 to 500 units for fully customized screens. Tooling costs (NRE) cover the lithographic masks for the ITO sensor and cover glass printing plates, and are kept highly competitive compared to Western manufacturers. Contact our engineering team for a detailed quote.
We address EMI issues by using custom touch sensor routing layouts, ground shielding layers on the flexible printed circuit (FPC), and advanced controller-level frequency hopping algorithms. This ensures stable operation near high-frequency medical machinery, electric motors, or switching power supplies.
