The Smartphone is becoming a necessity and not simply a luxury. Because of its advanced computing ability and connectivity, it is like owning a handheld computer with your mobile phone. Part of the capabilities of the phone is the presence of the touch screen technology. As people find it more convenient to use the fingers instead of the keypads, more customers are switching to the touch screen mobile phones. If you are an owner of the device, it is useful that you understand the process involved in its use.
Mobile phones use two technologies. You can choose from either the capacitive or the resistive type. Different cellular phone companies choose one over the other. To know their difference, here is how the technology works.
If the touch screen mobile phones use the capacitive technology, it means the panel consists of an insulator-like glass coated with a conductor. The smartphone works by the detecting the change in the electrostatic field and sending the signal to the controller for processing. Since the human body has electrical charge, the fingers create the needed electrostatic difference to start the electrical input. Generally, many companies find this technology more responsive to commands.
Resistive touch screen mobile phones involve the use of several thin layers of panel, including the two metallic conductors separated by a small gap. When an object touches the screen of the smartphone, the two metallic parts connect and create a change in the electrical current. The changes go to the controller and are processed as the data input. Unlike the capacitive technology where only contact with the human body can generate the input; in the resistive technology, you can use any object, like the stylus.
Whichever technology you opt for, the touch screen mobile phones are considered user-friendly. Even for computer beginners, the instructions to use the smartphone are very easy.
