The 3 ways to add PCAP touch?
The 3 ways to add PCAP touch?
1. Touch foil (also called touch film or touch skin)A touch foil is a thin, flexible PCAP sensor, only 100 microns thick, that is laminated behind a glass surface. The integrator builds it into the final product: a kiosk, a touch table, a vending machine or an interactive wall. Touch foils offer the most freedom: custom sizes, very thick glass, round and custom shapes, and outdoor use.
DISPLAX touch foils are the SKIN range:- SKIN ZEETO: 7" to 75", up to 10 touches, glass up to 20 mm, for harsh and demanding environments
- SKIN FIT: 32" to 135", up to 40 touches, glass up to 15 mm, for kiosks, signage and outdoor use
- SKIN ULTRA: 30" to 135", up to 100 touches, glass up to 10 mm, for premium large-format and multi-user experiences
- SKIN ROUND and SKIN SHAPES: round and custom-shaped touchscreens
For a ready-made glass module, the foil can be supplied pre-laminated with SKIN GLASS.
2. Touch module or touch overlayA touch module is a plug & play PCAP sensor with its glass, ready to add to a display. There are two kinds:- Integrated module: DISPLAX MESH is built into a display or kiosk during assembly. Standard sizes from 22" to 86", 10 touches, glass up to 5 mm. Read Metal Mesh Touch Panels: How They Work and When to Use Them.
- Overlay for existing displays: DISPLAX OVERLAY is a frame that fits over a signage display you already have (LG, NEC, Panasonic, Samsung, Sony, Philips), from 32" to 86". Read Touch Screen Overlay for LCD: How to Choose the Right One.
3. Touch display (all-in-one)A touch display is a finished product: display and touch together, ready to hang or install. Nothing to integrate.
