Touch screen technology has been on the market for a while now – specifically for gaming devices – although it’s only in the last 10 years that this translated to mobile technology. It has boosted online gaming numbers because of the ease of use on mobile phones, but how exactly has touch screen technology improved? The primary type of touch screen currently used in mobile technology (especially the iPhone) is a capacitive screen; these work with anything that holds an electrical charge – including human skin. They’re made up of materials that hold charges in an electrostatic grid of either a surface or projective screen. Resistive screens are analog devices that create a connection between two flexible resistive screens. They use your finger’s pressure to create a change in the flow of electricity; when a finger is placed on the mobile, a voltage drop is registered that allows the screen to work.
