The demand for display technology is being increased with the continuous invention of portable electronic devices and with the emergence of flexible, wearable, and transparent display devices. Touch screens have now become the part and parcel of our lives. We barely focus on the working of it while scrolling through Instagram or Facebook on our screens. we all have smartphones now in our hands, and we use them with ease and for entertainment. In today's generation, there is hard to find a person without an electronic gadget containing touch screens. This touchscreen have been used for a variety of different purposes since the first touch screen prototypes [2] saw the light of the day. Touch screens can at least be tracked back to the early 1970s. This touch screen critical component in display technologies that gear user interface operations. The next generations of touch screens are expected to sense multiple levels of pressure that 3-d touch screens do. To gear these 3-d touchscreens, transparent pressure sensors with high linearity over a working range that encompasses the pressure range of human touch i.e., 10 to 100kpa are required. In this work, the transparent and linear capacitive pressure sensor is reported with a transmittance of over 85% and high linearity over 5-100 kPa of pressure.[1] As years passed there are multiple types of touchscreen’s invented that made exceptional changes with upgradation in the types of touchscreens.Some of them can be listed as a) Resistance touchscreen b) Capacitive touchscreen c) Surface capacitive touchscreen d) Project capacitive touchscreen e) Surface Acoustic Wave (SAW) f) Infrared touchscreen screen
