Engineered to withstand extreme temperatures, mechanical stress, and harsh electromagnetic environments.
Integrating state-of-the-art sensory technology with rugged construction for unmatched human-machine interfaces.
Modern industrial and medical applications require human-machine interfaces that can register complex gestures even through thick protective cover glasses, gloves, and under moisture conditions. We construct custom Projected Capacitive Touch (PCAP) panels leveraging mutual-capacitance matrix structures. This allows up to 10-point simultaneous touch control with high noise immunity.
By pairing high-SNR controller ICs (such as EETI, Ilitek, and Cypress solutions) with customized sensor designs, we guarantee seamless touch response and zero ghost touches under heavy industrial EMI interference.
For applications where electromagnetic compliance (EMC) is highly critical, or where operators wear heavy industrial gloves in variable environmental states, our 4-wire and 5-wire analog resistive touch panels present an ultra-reliable, cost-effective alternative. Our resistive touch solutions deliver high precision, linear response, and are physically immune to electrical noise.
We supply custom resistive overlays fitted with structural IP65 and IP67 frames, providing reliable performance in marine displays, military hardware, and factory floor monitoring systems.
Founded in 2010 in Guangzhou, China, we are an established enterprise dedicated to the high-precision manufacturing, research, development, and system integration of capacitive touch panels, resistive touch panels, custom cover glasses, and full optical bonding modules (LCM assembly). We cater specifically to high-reliability applications, supplying both OEM and ODM services worldwide.
To support advanced optical integration, we run a dedicated 3,000 square meter plant equipped with certified Class 100, Class 1,000, and Class 10,000 cleanrooms. This pristine dust-free atmosphere is vital for handling OCA (Optically Clear Adhesive) and OCR (Optically Clear Resin) bonding processes, eliminating microscopic dust particles that cause optical refraction errors.
With an emphasis on manufacturing excellence, we have secured ISO 9001:2015 and ISO 14001:2015 certifications, ensuring every component, from raw ITO film to finished sensor modules, undergoes comprehensive environmental validation tests.

Operating out of Guangzhou, China positioning us at the center of the global optoelectronics supply chain. This physical proximity allows us to source raw ITO films, specialized sensor controllers, microcontrollers, and chemically strengthened cover glasses (Corning Gorilla, AGC, Schott) with minimal lead times. We leverage local industrial clusters to execute rapid design changes and deliver high-yield production runs at optimized unit economics.
Global procurement teams prioritize reliability, long-term lifecycle support, and strict certification alignment. We manufacture all materials under ISO 9001 and ISO 14001 guidelines. Our touch displays satisfy RoHS, REACH, CE, and FCC criteria. By delivering custom FPCs, shielding layouts, and tailored controller firmware, we help clients ease regulatory compliance paths for medical, transportation, and industrial final systems.
Air gaps between the LCD display panel and touch glass lead to light reflections, high power draw, and dust collection. Our optical bonding service eliminates this gap with Optically Clear Adhesive (OCA) or liquid resin (OCR). The resulting display boasts superior contrast, sunlight readability, high shock absorption, and completely removes the risk of condensation under humid operation conditions.
How our custom touchscreens excel across challenging operating environments worldwide.
In high-vibration settings, machine control panels must perform under grease, water spray, and heavy debris. Our custom wide-temperature capacitive touchscreens feature thick cover glass (up to 10mm) and high mechanical resistance. Industrial HMIs utilizing our 12.1-inch IP65 resistive or capacitive solutions prevent false triggers from liquid spray, maintaining uninterrupted performance on automated assembly lines.
Hospital and clinical settings demand surgical-grade touch accuracy, support for gloved hand operations, and resistance to aggressive chemical disinfectants. We supply medical device manufacturers with custom optical bonded capacitive screens that feature Anti-Fingerprint (AF) and Anti-Glare (AG) chemical etchings. These sensors support precise calibration for multi-touch gestures, operating reliably near high-frequency electrosurgical equipment without electromagnetic interference.
Outdoor kiosks, palm-print scanners, and smart ticketing terminals are exposed to direct sunlight, temperature variations, and vandalism. We resolve readability and wear challenges with UV-resistant coatings, IK08/IK10 impact protection, and optical bonding. This guarantees readability under sunlight and reliable operation in temperatures from -30°C to +85°C.
Our proactive R&D addresses critical trends shaping the next decade of human-machine interfaces.
The demand for high-readability displays under ambient sunlight is rising. Standard displays act as mirrors, causing user eye fatigue. By chemically etching cover glass to form Anti-Glare patterns, or applying physical vapor-deposited Anti-Reflective thin-films, we minimize reflection to less than 1% while maximizing display contrast.
Security kiosks and payment systems are increasingly merging touch surfaces with optical biometric systems. We configure custom touch overlays with targeted transparency zones and custom-etched patterns to enable palm print and fingerprint scanning directly through the display panel, streamlining structural design and improving security.
Operating a touchscreen in rain or offshore maritime applications often leads to tracking errors as water droplets bridge the capacitance gap. We resolve this by tuning the controller firmware using self-capacitance sensing to register touch inputs, while mutual-capacitance tracking is used to reject large pools of water, ensuring safety-critical performance.
Modern cockpits and machinery consoles are replacing flat interfaces with curved displays. We design custom curved cover glasses using precision thermal bending molds. The touch sensor is laminated on 3D contoured surfaces, maintaining structural uniformity and seamless touch response across the entire curvature.
