Explore our leading industrial capacitive and resistive touch screen modules, engineered with high optical clarity, IP65 protection, and optical bonding technologies.
Evaluating CTP vs. RTP Technologies for Mission-Critical Engineering Projects
Modern touch screen interface architectures are divided into Projected Capacitive (PCAP/CTP) and Resistive (RTP) technologies. Selecting the proper technology requires analyzing environmental variables, durability thresholds, and user interaction mechanics.
Projected Capacitive (PCAP): Utilizes a sensor grid to measure changes in capacitance when a conductive object (like a finger) approaches. Supports multi-touch, gestural inputs, and features superior optical transmissivity (>90%). Ideal for medical HMIs and interactive outdoor kiosks.
Resistive Technology: Operates on pressure-sensitive contact between conductive ITO layers. Extremely cost-effective, immune to EMI/RFI interference, and fully responsive to gloved fingers, styluses, and non-conductive tools. Highly suited for heavy industrial machining and harsh factory floors.
Founded in 2010 and located in Guangzhou, China, we are a high-tech company dedicated to the research, development, production, sales, and service of resistive touch panels, capacitive touch panels, cover glass, and module optical bonding products. We provide customized production of various touch screens, as well as OEM and ODM services.
Our facility spans a total plant area of 3,000 square meters, utilizing dedicated R&D, production, marketing, quality control, purchasing, and human resource departments. To meet rigorous quality controls across multiple touch sensor configurations, we operate state-of-the-art Class 100, Class 1,000, and Class 10,000 dust-free workshops.
Quality Assurance & Compliance: Our manufacturing processes are fully certified to ISO 9001:2015 and ISO 14001:2015, ensuring every unit meets environmental and international performance specifications.
