RTP Resistive Touch Panel

Product Description

The QIHAN RTP (Resistive Touch Panel) series is designed for industrial HMI, medical devices, automotive systems, POS terminals, and embedded control applications. Using pressure-sensitive touch technology, RTP generates coordinate signals through physical contact between conductive layers, enabling accurate operation with fingers, gloves, stylus pens, and other non-conductive objects.

QIHAN offers standardized resistive touch panels from 2.4 inch to 21.5 inch, supporting both 4-wire and 5-wire architectures. The RTP solution provides excellent anti-interference capability, stable operation in harsh environments, and long-term reliability for industrial applications. Technical characteristics including durability and touch accuracy are based on RTP structural behavior and calibration characteristics.
