What is Resistive Touch Screen

Touch screen’s appliances are rapidly developing niche market. To better understand the durability of such appliances is necessary to have specific information about different types of touch screens. There are three types of touch screen of which resistive touch screen are widely used and considers somewhat reliable from the other types of touch screens.

Resistive Touch Screen Mechanism

The mechanism used in the resistive touch screen is pressure detector. It senses the pressure on a specific place and carried on the intended action. Resistive touch screen is made up of three layers. First layer is made up of conductive layer and second is sensitive layer.

These layers are placed upon one another with a space on the glass and further coated with the indium tin oxide a resistant chemical to protect the screen from scratches. When pressure is applied on the screen or the system comes into operational condition current passes through it. In response to the pressure both layers strike with each other and current passes through the space, detects the pressure point by the operating system which resultantly carries out the command.

Resistive Touch Screen Uses

Resistive touch screen mechanism replaces the use of mouse and keyboard for monitor’s direct use. Similarly, mobiles are also available with touch screen with the alternate mode of touch pad system. But complete touch screen enables mobile is more in demand. People are lot more busy and instead of tracing the menu through multiple buttons they better use the touch screen for quick approach. Everything is now just the matter of touch now whether with the finger or stylus.

Advantage and Disadvantages of Resistive Touch Screen

The first and the most important advantage of resistive touch screen is that it is long life. Its durability and reliability are the features which make it enable to incorporate in heavy industry machinery, commercial markets and electronic equipment’s. Another important advantage of this resistive touch screen is that we can touch and perform desired action by touching the screen with anything. There is no limitation to operate the screen with any special object. The screen can be touched by stylus, fingers or nail hence flexible enough as compared to other touch screen technologies. As it is pressure sensitive screen so anyone can use it.

While looking at the negative aspects of the resistive touch screen, the first thing comes into notice is its screen clarity. Due to the production of electric field in response of the touch it emits 75% of light which make the image relatively bulky and dim. Production of bulky image spoils its market.

Resistive Touch Screens are not expensive when compared to other touch screen technologies. Therefore used at commercial basis. In past when people were not aware of touch screen rather a limited number of people were introduced to this technique, Resistive touch screen was incorporated especially in heavy machine control unit to save the time and make the work easy. With the help of touch display switching system become more convenient and replace the big control unit with a compact touch display with all the touch buttons.

Resistive touch screens are pressure sensitive. This feature where lend a hand to perform different function easily and in less time there it does not allow the pressure of full hand on the screen. It is unable to sense touch of stylus and hand at a time. There is need to define the touch by activating the sensor for one and deactivating for the other. In another case multi-touch sensor can also be introduced. Resistive screen is passive mode so is better used with the active touch like finger and mostly avoid the touch of stylus which is also a passive medium.
