subject: Why Resistive Touch Screen Is A Popular Choice? [print this page] Touch Screen is a two-dimensional sensing device and is constructed out of two sheets of material that are separated slightly by spacers. The two sheets are coated with a resistive substance called indium tin oxide (ITO). The ITO is uniformly and thinly sputtered onto both the glass and the PET Layer (Polyethylene as a flexible top layer). Then tiny bumps called spacer dots are added to the glass side to protect the PET film from sagging and creating an accidental or false touch.
The two main types of Touch Screens commonly used in phones nowadays are Resistive and Capacitive Touch Screen. Resistive Touch Screen uses pressure to work on a circuit telling the device the location of a particular pressure. On the other hand, Capacitive Touch Screen uses electrode and not pressure to sense the conductive properties of an object.
Touch Screen Display are the most affordable type of touch screens and are applied in PDAs and various digital devices. They are known for their high durability but the clarity is not in par with other touch-screen types of course. The other concern is that they are very sensitive to sharp objects and can be easily damaged.
The various types of Resistive Touch Screens in use are 4-wire, 5-wire, 7-wire or 8-wire screens. Out of these, the 4-wire resistive touch screen is the most common. The various layers of a 4-wire resistive touch screen panel are a rectangular flexible top layer, a transparent conductive coated layer, air-gap or isolation spacers, another transparent ITO layer and in the end a stable layer.
Cost Effectiveness of Analog Resistive Touch Screen is a reason for its immense popularity. Additionally, the screen is immune to different variations in temperature and pollution in environment that makes it the most suitable and in-demand touch screens. Another interesting plus point is that the electrical current running through the layers is not affected by fluctuations in temperature. Other than the use of fingers, one can also use styluses, pencils, etc. because the screen does not depend on the conductive potential of the object that is used to register a touch on screen.
