JIC_V1_N1_A01 Arun S Raj Mani R. Vasagam Meenakshi B. Sundaram Habibullah H. Sait Journal on Instrumentation & Control Engineering 2321 – 1148 1 1 1 8 Capacitive, Infrared, Multi-Touch, Resistive, Transistor, Sustainability, Touch Screens In our day to day life, we physically interact with electronic devices is changing through our technological research. This change has led to recent techniques, including the development of touch screen technology. In touch screen technology, the operator is given an other method of how we can interact with a device. This technology already operates in three distinct ways: resistive systems, capacitive systems, and infrared systems. This paper will propose, focus and compare these technologies with a new concept of touch screens which works using transistors, focusing on the differences in application.
