RESISTIVE TOUCH SCREENS
Comprised of several layers, resistive touch screens are the most common type of touch screen found in the market. Relying on resistance, the pressure applied by fingers causes the screen to respond. Due to the fact that slight pressure on the top layer of the touch screen transfers to the adjacent layer and causes a cascade of signals, anything can be used on resistive touch screens- including fingers (both bare and gloved), fingernails, and a stylus of any size or shape. By being able to offer excellent durability and resolution, resistive touch screen technology is used in a variety of applications and environments.
Advantages: low production cost, high resistance to dust and water, can be operated with more than just a finger, ideal for handwriting recognition.
Disadvantages: sensitivity is low – must press harder than when using a capacitive touch screen, poor contrast due to additional reflections caused by an extra layer of material placed over the screen, does not support multi-touch.Advantages: low production cost, high resistance to dust and water, can be operated with more than just a finger, ideal for handwriting recognition.
Popular Uses: most cell phones, PDAs, handheld consumer applications.
