Ever wonder what happens when you rub a rubbery material, such as a rubbery finger or a soft rubbery material, against your touch screen? What happens? The interaction between the material and the electric field that are produced by the contact makes a friction (or force) between the two. When the finger makes contact with the screen the electric field generated by the display is produced by the device, causing it to create an electric current. How does rubber work on touch screen?
The working mechanism behind this phenomenon is simple. When the finger applies pressure to the rubbery material it creates a slight amount of pressure behind the material. This slight amount of pressure is picked up by the electronic circuit board, which then causes a current. The more of this current that is generated the more the battery can charge. Without the rubber glove the finger would just graze against the screen rather than applying any pressure at all.
This same principle also explains why rubber gloves make the skin of our hands itchy. If you rub your fingers together it feels really uncomfortable, but if you just put your hands inside a rubber glove it doesn’t cause any pain. This is the same for a touch screen TV. When you press a screen it feels great, but it’s not until you put a little bit of pressure there that it registers.
When manufacturers are designing new touch screens, they have to keep these principles in mind. This is why many screens now come with a built-in rubber coating on the back. This coating can help to reduce the discomfort of using the screen. However, sometimes you just don’t want to use the built-in glove.
Many people like to purchase their own special glove to use when handling the touch screen. They may choose to get a small, lightweight rubber material so that they can feel much more comfortable using the device. You can find gloves made from a wide variety of materials including, but not limited to: rubber, vinyl, and satin.
The last question that we need to answer is, does rubber work in the case of liquid spillages? Well, in the case of liquid spills, no. In most cases you are going to want to find some type of absorbent material to catch the liquid. So, again, the rubber isn’t going to work in this situation.
