What is about Touch Screen and Resistive Screen? Explained!

When touch screen technology first hit the mass market the general opinion was that it was a useless technology that would pass much like any other with many people clinging tightly to be analog buttons on their phones and claiming that things like texting could never be the same without them. But fast forward to today and it is practically impossible to find any of those previous skeptics who don't currently have their faces buried in a new touchscreen device tapping and swiping away. Now the question arise how did it all get started? Well the first touch screens were developed all the way back in the 1960s using a capacitive design which works by coating glass with an electrically conductive surface now as we all remember from the first matrix film, human beings are basically just batteries waiting around to be harvested by the machine so whenever on of our conductive little digits comes in contact with this types of screen the processor can sense the difference in charge as an input and although this technology was developed decades ago it is still used in highest end smartphones today. But just like anything else these wonderful devices don't function well under certain adverse conditions like condensation from cold damp weather can get to your screen and get it wet causing it to register random presses and surface material such as dirt or even the oil from your fingers can also impede a capacitive touchscreens functionality mean not to mention that they can't normally be used with a gloved hand. So in case where speed and sensitivity are not as important as reliability and functionality, resistive screens can be a better option you'll often see these on ATMs, cash registers, etc. where durability really counts so these operate by having two thin sheets set apart by a small gap one of which has a current applied to it while other is connected to voltage sensors. Whenever the screen is touched it causes the current and sensors layers to make contact registering an input because the outer surface of the screen does not contain any sensitive electronics resistive touchscreen stand up very well to environmental hazards and careless users and can be used with gloves. Usually you won't see resistive screens on portable devices due to their bulk and the lack of precision.

What's the future of touch screen? Well you can expect more than just allowing touching and swiping from the touch screen. What you say if somebody tells you that touch screen can touch you back. Yes, some researchers are now trying to answer that very question with a number of new approaches for instance the prototype FUSA2 display from Japan is made of optical fibers likewise Ultra Haptics from England is launching a new system that enables both touch inputs and feedback in the air using ultrasonic pulses and Disney research is working on similar system that uses precisely directed blown air for virtual reality experiences, gaming, etc. They are also developing the Tesla Touch system which uses minute changes in voltage on the touch screen itself to actually make the screen with different textures, imagine a picture of sand paper that feels rough when you touch it.

The future of touchscreen is bright and let us hope we get a good, reliable and a dope touchscreen in near future.
