What is the difference between Resistive and PCAP touch screens?

Resistive technology relies on pressure sensitivity, making it immune to noise and usable with any object (gloves, stylus). Projected Capacitive (PCAP) uses electrical capacitance, offering multi-touch support, higher transparency, and a durable glass surface similar to smartphones.

Why choose 5-Wire Resistive over 4-Wire?

5-Wire Resistive panels place the electrodes on the bottom glass layer rather than the top film. This means even if the top film is damaged or scratched, the touch panel continues to function accurately. It offers 35 million touches durability versus 1 million for 4-wire.

Is Infrared (IR) touch suitable for large displays?

Yes, IR touch is ideal for large formats (up to 100+ inches) like digital signage and interactive whiteboards. It offers high light transmission (no glass overlay needed) and works with gloved hands, but can be sensitive to strong sunlight interference.

Overview

Industrial Touch Panel Applications

Touch panels are the standard interface for modern Human-Machine Interfaces (HMI). From factory automation and ATMs to medical devices and rugged tablets, touch technology is ubiquitous.

AiM Touch provides a comprehensive portfolio including 4-Wire/5-Wire Resistive, Projected Capacitive (PCAP), Surface Capacitive (SCAP), Infrared (IR), and Surface Acoustic Wave (SAW). We help you select the right technology based on environmental factors like water resistance, glove operation, and electromagnetic interference (EMI).

Common Questions: Choosing the Right Tech

Q: Should I choose Resistive or PCAP touch?

A: Choose Resistive if your environment is dirty, oily, or requires input with heavy gloves or any object. It is cost-effective and noise-immune. Choose PCAP if you need a smartphone-like experience (swiping, zooming), high durability (glass surface), and superior optical clarity.

Q: Which touch technology is best for outdoor Kiosks?

A: For outdoor use, Projected Capacitive (PCAP) is generally preferred due to its ability to be sealed (IP65) and UV resistance. Infrared (IR) is also a good option for large displays as it is not affected by sunlight (if high-quality sensors are used) and has high light transmission.

Q: Does AiM Touch provide technical theory documents?

A: Yes, you can download detailed PDF guides for each technology (Resistive, Capacitive, IR, SAW, etc.) from the sections above. These documents cover operating principles, electrical specs, and mechanical characteristics.
