FAQs
What types of touch panels are available?
The two most common technologies are:
- Capacitive Touch Panels (PCAP):
Multitouch-capable, highly responsive, and transparent – ideal for smartphones, industrial displays, and medical devices. - Resistive Touch Panels:
Pressure-sensitive and operable with gloves or styluses – ideal for industrial environments or hygiene-critical applications.
What is the difference between capacitive and resistive touch technology?
Capacitive: Responds to touch from conductive objects such as fingers. Supports multitouch, but is not ideal for use with gloves.
Resistive: Responds to pressure – whether from a finger, stylus, or glove – and continues to function reliably in wet or dirty environments.
Are your touch panels multitouch-capable?
Yes, especially capacitive panels support two or more simultaneous touch points, enabling gesture control such as zooming and swiping.
Can touch panels be optically bonded?
Yes. With optical bonding, the gap between the display and the touch sensor is filled with a clear adhesive or resin, offering:
✔ Improved sunlight readability
✔ Reduced reflections
✔ Increased stability & protection against moisture
Are your touch panels suitable for harsh industrial environments?
Yes. We offer rugged touch solutions with:
- IP65 or IP67 protection
- Chemically and scratch-resistant surfaces
- Extended temperature range (–30 °C to +85 °C)
Can touch panels be integrated into custom housings?
Absolutely – our panels are available in various sizes, shapes, and mounting options to fit seamlessly into your enclosure design.
Are your touch panels operable with gloves?
✔ Resistive touch panels are always glove-compatible.
✔ Capacitive panels can be calibrated for glove or stylus operation upon request.
