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.
|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|
|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.|
