Touch Screen Technologies
Capacitive Touch
The most common technology for commercial touch screens.
How It Works: An electrical field on the screen surface detects the conductive properties of a finger.
Types:
| Type | Touch Points | Durability | Best For |
|---|---|---|---|
| PCAP (Projected Capacitive) | 10-80+ | Excellent | Most commercial |
| Surface Capacitive | 1 | Good | Simple applications |
Advantages:
- Excellent responsiveness
- Multi-touch support
- Durable surface
- Good optical clarity
- Glove-compatible versions available
Limitations:
- Requires conductive touch (finger or special stylus)
- May not work with gloves (standard)
- Water on screen can cause issues
Best For:
- Indoor kiosks
- Retail applications
- Corporate environments
- Most touch applications
Infrared (IR) Touch
How It Works: LED beams create an invisible grid above the screen. Touching breaks the beams, registering location.
Advantages:
- Works with any object (finger, glove, stylus)
- No special screen coating needed
- Scalable to very large sizes
- Works in bright light
Limitations:
- Bezel frame required
- Can be affected by debris
- Parallax at edges
- Generally single-touch (multi-touch possible but expensive)
Best For:
- Large format displays (65"+)
- Interactive video walls
- Outdoor applications
- Rugged environments
Surface Acoustic Wave (SAW)
How It Works: Ultrasonic waves transmitted across the screen surface are absorbed when touched.
Advantages:
- Excellent optical clarity
- Durable
- Good resolution
Limitations:
- Requires direct touch (no gloves)
- Sensitive to contaminants
- Limited touch points
Best For:
- High-traffic indoor kiosks
- Gaming
- ATMs
Resistive Touch
How It Works: Two flexible layers separated by a gap; pressure pushes them together to register touch.
Advantages:
- Works with any object
- Low cost
- Works with gloves
- Tolerates contaminants
Limitations:
- Single-touch only
- Less durable
- Poorer optical quality
- Dated technology
Best For:
- Industrial environments
- Legacy systems
- Cost-sensitive applications
