Levensduur en Slijtage van Touchscreens

Life and Wear of Touchscreens

The lifespan of a touchscreen depends greatly on the technology. Resistive screens wear out from physical pressure, which can damage the conductive layers. Modern Projected Capacitive (PCAP) screens, as in smartphones, do not wear out from touch because they have no moving parts. The sensor has a theoretically infinite lifetime. Failure in PCAP screens is usually caused by external factors, such as a broken glass, a faulty controller or environmental damage from moisture or heat, rather than loss of sensitivity through use.

Projected Capacitive (PCAP)

PCAP displays, the standard in modern phones, operate through an electric field and have no moving parts. The sensor itself does not wear out from touch and has a virtually unlimited electrical life. As a result, sensitivity does not decrease with normal use. The hard glass surface provides excellent durability.

Wear Resistant Screens

Resistive touchscreens register input by physical pressure that contacts two conductive layers. Repeated pressing in the same location can physically wear down these layers, resulting in reduced sensitivity and accuracy. Longevity is often limited by a maximum number of touches.

External Causes of Failure

Although the PCAP sensor itself does not wear out, the screen can fail due to external factors. The most common causes are physical damage such as cracks, a faulty control electronics (controller), or the degradation of internal components due to exposure to moisture, extreme temperatures or UV radiation.

Wear Oleophobic Coating

Many modern screens have an oil-repellent (oleophobic) coating that can wear away over time. This does not affect the touch sensitivity of the sensor, but it does make the screen feel more rigid and fingerprints and smudges more easily left behind.
