Projected capacitive touchscreens have become increasingly popular in recent years. You can find smartphones, tablets, smartwatches, computer monitors and other devices powered by this technology. Projected capacitive, of course, is a type of capacitive touchscreen technology. Like other capacitive touchscreen technologies, it measures capacitance to detect touch commands. But projected capacitive touchscreens offer several advantages over other technologies.

Supports High Resolutions

Projected capacitive touchscreens feature high-resolution displays. All touchscreens, of course, have an integrated display. They must project images so that you can control them by tapping or touching the display interface. Projected capacitive touchscreens, however, support high resolutions that aren’t found in other touchscreen technologies.

No Moving Parts

You can rest assured knowing that there are no moving parts in projected capacitive touchscreens. Projected capacitive touchscreens use a non-mechanical method of operation. They don’t detect touch commands mechanically. Instead, projected capacitive touchscreens leverage capacitance.

When turned on, projected capacitance touchscreens will produce a uniform electrostatic field. They will constantly measure this electrostatic field while looking for changes in capacitance. If you tap or touch the display interface with a conductive object, you’ll change the capacitance. The projected capacitive touchscreen will then register this change in capacitance as a touch event.

Scratch Resistant

Projected capacitive touchscreens are scratch resistant. They feature a top layer that’s made of tempered, scratch-resistant glass. Even when used on a daily basis, projected capacitive touchscreens typically won’t develop scratches. They can withstand constant, use while retaining their pristine and transparent top layer.

Multi-Touch Commands

You can perform multi-touch commands when using a projected capacitive touchscreen. Multi-touch commands involve multiple points of contact. You can always perform traditional touch commands by tapping or touching a single area of the display interface. If a device supports multi-touch commands, though, you can tap or touch multiple areas of the display interface at the same time.

Surface capacitive touchscreens typically don’t support multi-touch commands. Projected capacitive touchscreens, on the other hand, do support multi-touch commands.

Thin Gloves

It’s a common misconception that all capacitive touchscreens require direct contact with a conductive object. If you tap or touch the display interface with a nonconductive object, it won’t change the device’s capacitance. The good news is that many projected capacitive touchscreen support the use of thin gloves.

Gloves are nonconductive. If they are thin, however, electricity may be able to flow from the display interface of a projected capacitive touchscreen to your fingertips. Thin sugicial gloves, for instance, will typically work with projected capacitive touchscreens.
