Levensduur en Slijtage van Touchscreens

Life and Wear of Touchscreens

The lifespan of a touchscreen depends greatly on the technology used. Modern PCAP (Projected Capacitive) screens, such as those found in smartphones, have no moving parts and do not wear out from touch. The glass surface is durable and the sensor has a theoretically infinite lifespan. Loss of sensitivity is usually caused by external factors such as damage from drops, moisture, or a faulty controller, not by normal use. Older resistive screens, on the other hand, do wear out due to the physical pressure required to make contact between two conductive layers.

PCAP Sustainability

Projected Capacitive (PCAP) screens have no moving components that wear out physically. Detection is based on the disruption of an electric field by a finger, not on pressure. The hard glass surface does not degrade when touched, which means that the sensor itself does not wear out through use.

Resistant Wear

Unlike PCAP, resistive screens require physical pressure to bring two flexible, conductive layers into contact with each other. Repeatedly pressing the same location can permanently deform these layers or damage the conductive coating, resulting in a progressive loss of sensitivity.

External Failure Factors

Although the PCAP sensor itself does not wear out, its functionality can be impaired. Common causes of defects are physical damage (cracks), moisture infiltration, or a malfunction in the control electronics (the touch controller). Sensitivity is therefore more likely to be affected by external damage than by internal wear and tear.

Sensitivity over Time

An undamaged PCAP screen should not experience any noticeable loss of sensitivity during the economic life of the device. If sensitivity decreases, this is more likely to be due to a software problem, a faulty controller, or invisible damage than to the 'age' of the sensor.
