정전식 vs 저항막식 터치
산업용 TFT LCD 모듈용 정전식(CTP) 및 저항막식(RTP) 터치 패널 비교。How Each Technology Senses Touch
Resistive panels measure pressure: two conductive layers touch where you press, so any object works — finger, gloved hand, stylus, even a pen cap. PCAP measures changes in an electrostatic field, so it needs a conductive input (bare finger or special capacitive stylus/glove), but it delivers true multi-touch and far better optics.
Side-by-Side Comparison
| Criterion | Resistive (RTP) | Capacitive (CTP) |
|---|---|---|
| Touch points | Single | Multi-touch |
| Gloves / any stylus | Works with anything | Needs conductive input |
| Optical clarity | Good (~80%) | Excellent (90%+) |
| Water / contaminants | Tolerant | Can false-trigger |
| Actuation life | Moderate | Very high (glass front) |
| Unit cost | Lower | Higher |
Choose RTP When…
- Operators wear heavy gloves — food processing, field service, cold chain
- The UI is menu-driven and single-touch is enough
- Budget is tight and volumes are moderate
- Wet or dusty environments would disturb capacitive sensing
Choose CTP When…
- Customers expect smartphone-like interaction — pinch, swipe, zoom
- The display is a selling point of the product, not just a component
- High actuation life and glass-front durability matter
- The enclosure benefits from a flush, modern look
