✋ Touch Technology Types
Here are the common touch technologies you’ll find in 19-inch displays:
| Touch Type | How It Works | Pros | Cons |
|---|
| Projected Capacitive (PCAP) | Detects touch via changes in an electrostatic field | Fast, multi-touch, durable, works with light gloves | Higher cost |
| Resistive | Two layers press together when touched | Works with stylus or gloved hands, cheaper | Not very durable, limited multi-touch |
| Infrared (IR) | Light beams across screen broken by finger | Durable, works with anything | Less precise, bezel required |
| Surface Acoustic Wave (SAW) | Acoustic waves interrupted by touch | Clear image | Can be affected by dust or water |
Most modern 19″ touch displays use PCAP for responsiveness and multi-touch support.
