Capacitive has become the world’s leading touchscreen technology. More touchscreen devices use capacitive technology than any other type of touchscreen technology. As the name suggests, it involves the use of capacitance. Capacitive technology measures changes in capacitance. If it detects a change in capacitance, capacitive technology will register it as a touch event.
Whether you currently own a capacitive touchscreen or are planning to buy one in the near future, however, there are several tips you should follow when using it.
Preserve the Oleophopbic Layer
You should preserve the oleophobic layer on the capacitive touchscreen. Most capacitive touchscreens have a glass top layer, which is covered in a layer of oil-repelling liquid. Known as an oleophobic layer, it protects the glass layer from fingerprints.
Cleaning the capacitive touchscreen with rubbing alcohol or other solvents may dissolve the oleophobic layer. To preserve it, avoid using solvents such as these to clean the capacitive touchscreen. Instead, use a microfiber cloth to clean the capacitive touchscreen.
Wear Thin Gloves
Depending on the particular type of capacitive touchscreen, you may not be able to use it while wearing thick gloves. There are surface capacitive touchscreens, and there are projected capacitive touchscreens. Surface capacitive touchscreens only feature conductive contacts on one side of the insulator layer.
Projected capacitive touchscreens are more advanced than their surface capacitive counterparts. They can often detect touch commands through thin gloves, such as surgical gloves. Surface capacitive touchscreens, conversely, require direct contact with a conductive object. If you wear globes — even thin gloves — surface capacitive touchscreens may fail to register your touch commands.
Choose a Capacitive Stylus
There are styluses available specifically for capacitive touchscreens. They are called “capacitive styluses.” Capacitive styluses look like most other styluses: They are pen-shaped devices with a blunt tip that you can use to perform touch commands.
Capacitive styluses are different from other styluses, though, because they contain a conductive tip. The conductive tip allows them to mimic the conductive properties of the human body. Your finger is conductive. When you touch a capacitive touchscreen with a bare finger, your body will absorb some of its electrical charge.
Capacitive styluses work in this same way. They have a conductive tip that’s able to absorb the electrical charge of a capacitive touchscreen. Therefore, if you want to use a stylus with a capacitive touchscreen, you should choose a capacitive stylus. Only capacitive styluses will work with capacitive touchscreens.
