What are the differences between resistive and projected capacitive touch screens?sarah2019-11-12T12:03:06-08:00
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.
Projected Capacitive (PCAP)
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.
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
Good: Can be improved with additional options which increase cost.
Reflections from an extra layer of material placed over the screen result in reduced contrast.
