FAQs

Frequently Asked Questions

Contact Us
What’s the difference between resistive and capacitive touch screens?

Resistive uses pressure; capacitive (like PCAP) uses the electrical properties of the human body.

Can the screen be operated with wet fingers?

Yes, our wet-touch PCAP technology allows operation even with water droplets on the surface.

Which interfaces are available for your touch panels?

We offer I2C and USB touch interfaces depending on the application.

What types of touch screens do you offer?

We provide both resistive and projected capacitive (PCAP) touch screens.

What is an “active area” in a TFT display?

It refers to the portion of the screen that actually displays content (excluding bezels).
