March 31, 2017, 01:04:52 PM
Touch Screen started with the discovery of the electronic touch interface in the year 1971 by Dr. Samuel C. Hurst. Touch screen technology became famous with retail systems when point of sale system was used there. Touch screen is basically a display screen which can recognize human touch. It allows the user to interact with the screen by touching pictures on the screen. Human touch is the same as when a button or a picture is clicked using mouse or keyboard click. It is used in many systems like ATM machine, coffee kiosks and many other user end systems. There are mainly three kinds of touch screen technology like surface wave, Capacitive and Resistive. The three main components of touch screen are controller, software drive and touch sensor.
  A touch screen sensor is a glass panel whose surface responses to touch. The touch sensor is layered on the display screen so that the responsive surface covers the viewable video screen area.
