The Touchscreen technology has been driving the market presently and every gadget is rushing to join
this bandwagon. While ATM machines and industrial control panels were the only place where we could
avail from a touch, the case is no more the same with every other gadget imbibing the touchscreen
technology today. Apple redefined the Touchscreen technology in 2007 with its iPad. The spontaneity
and effortlessness that Touchscreen grants is the key reason for its popularity.
The major components of Touchscreen technology are the touch sensor is a mantle that responds to
the touch either resistive or capacitive. A touch causes the change in the flow of electric current that
runs through the sensors in order to determine the location of the touch. The controller facilitates
conversion of these voltage sensors into signals that decodes the devices (computer, mobile). Software
comprehends the sensor with the necessary information imputed by the controller.
The two major kinds of Touchscreen technology available are:
Resistive Touchscreens: There exist two layers of electrically conductive material that is separated
by insulating dots. The circuit is completed when two layers touching each other. The information
regarding the point of contact is consequentially sent for processing to the computer controller for the
desired action to take place.
Advantages of Resistive touchscreen:
Longer life
Cheap
Durable with the protective layer on the glass panel
Easy to use
Responds to any object including finger, pen, stylus, etc
Disadvantages of Resistive touchscreen
Content isn’t clear and might appear bulky
Image isn’t sharp as it emits less light relatively
Requires increased pressure comparatively to operate
Does not respond to multi- touch
Poor visibility during sunlight
Consumes more power
Capacitive touchscreen: There are two major types of capacitive touchscreens where one can
respond to multiple touches while the other cannot. There is a single layer known as the grid sealed with
an electro conductive material. With a finger touch, the charge from the capacitive layer transfers to the
finger, determining the contact point resulting in the desired action to take place.
Advantages of Capacitive touchscreen:
Clear screen as it emits less light
Long life
Responds to multiple touch
Smoother response
Consumes less power
Clear visibility as there is only one layer
Disadvantages of Capacitive touchscreen:
Does not respond to anything other than finger generally
Expensive
Lesser durability
