Resistive vs. Projected Capacitive
A resistive touch screen is made of several layers. A capacitive touch screen consists of an insulator coated with a transparent conductor. Use the table below to determining which type of touch suits your project best.
If our standard modules are not a fit, we can provide customized modules if you have sufficient production volumes.
| Resistive | Projected Capacitive (PCAP) | |
|---|---|---|
| Cost | Lowest Cost | Additional Cost: Price difference depends on panel size, touch manufacturer, and annual production volume. |
| Touch Screen Control Type | Requires pressure on the touchscreen. | Can sense proximity of finger. |
| Need to touch with thick gloves or an object? |  | Dependent on the conductive nature of human body. PCAP only works with thin gloves or a finger. |
| Touch Points | Single Touch Only | Dual or Multi-Touch Possible |
| False Touch Rejection | False touches can result when two fingers touch the screen at same time. | |
| Immunity to EMI | Better | Good: Can be improved with additional options which increase cost. |
| Appearance | Reflections from an extra layer of material placed over the screen result in reduced contrast. | |
| Sliders or Rotary Knobs | Possible, but not graceful. | |
| Cover Glass | Not available. | See sample with imprinted black border and logo. |
| Immunity to Objects/Contaminants on Screen | | If water gets on the screen, PCAP can mistake it for a touch. Resistive has to be touched. |
| Resistant to Chemical Cleaners | No | |
| Durability | Good | Better |
| Impact Ball Drop Test | Shards contained. | Can be improved with additional options which increase cost. |
| Scratch Resistance | More easily scratched or damaged. | |
| UV Degradation Protection | Less protection. | |
