Why does dust always collect on television and computer screens?

Answer 1

This is mostly true on the older ones, since the screens held an electrostatic charge. So the electron charge attracts dust that has the opposite charge. If the newer stuff is getting dusty, it is a static charge too, but the device is not actively creating it. Plastic can be prone to building a charge on its own or with rubbing.

Answer 2

Dust collects on television screens for two reasons. The first is that televisions generate heat and as they warm up, so air rises past the front and back of the television due to convection currents. The moving air delivers a stream of airborne dust to the television as it passes.

Next, the television builds up a little static charge when it is on. The charge was far greater with older CRT televisions but even with the later LCD televisions, and plasma screens, the charge is still present. It is this charge that encourages the dust particles to stick to the television.

There are a number of anti-static cleaning sprays that will reduce the problem of dust build up but they won't eliminate it. If you choose to use one, make sure it states that it is safe for use on television screens and electronic equipment.

Answer 3

It is because the static electricity that it gives off attracts the dust particles.
