GreenTouch 21.5" 4-Wire Resistive Touch Screen for Reliable Industrial Applications

2026-09-04 10:52:25

As industrial automation, self-service systems, and embedded equipment continue to expand, reliable and flexible touchscreen technology remains essential for human-machine interaction. The GreenTouch 21.5" 4-Wire Resistive Touch Screen is designed to provide stable touch performance for industrial HMI systems, kiosks, POS terminals, control equipment, and other professional applications where durability, accurate input, and integration flexibility are important.

Based on proven 4-wire resistive touch technology, the 21.5-inch resistive touchscreen is available with ITO Film + ITO Glass or ITO Film + ITO Film structures. Its flat and slim construction has a total thickness of approximately 2.3 mm, making it suitable for integration into a wide range of embedded devices and industrial equipment.

The touchscreen supports both finger and pen stylus input, providing accurate touch response, high sensitivity, smooth writing, and stable operation. With light transmission of at least 75% and a surface hardness of 3H or higher, the screen is engineered for frequent-use environments. A mist hard coating and anti-Newton ring design help reduce scratches and unwanted optical interference. The touchscreen can also be sealed against contamination and supports NEMA 4/4X/12 requirements for applications requiring additional environmental protection.

Reliability is another key advantage of the GreenTouch 21.5" 4-wire resistive touchscreen. It is designed for more than one million touches and supports an operating temperature range from -20°C to 60°C and a storage temperature range from -30°C to 70°C. USB and RS232 interfaces are available, while compatibility with Windows, Android, and Linux makes integration easier across different industrial and commercial platforms.

For OEM and ODM projects, GreenTouch provides customization options including customer logos, FPC outlet locations, ITO glass thickness, touchscreen dimensions, and matte anti-Newton ring configurations.

Combining proven resistive touch technology, flexible input methods, industrial reliability, and customizable design, the GreenTouch 21.5-inch 4-Wire Resistive Touch Screen provides a cost-effective touch solution for industrial automation, self-service terminals, retail equipment, embedded HMI systems, and other professional touchscreen applications.
