friends,
we daily see so many touch screen mobiles,some are having easy touch sensor and some are difficult to operate...
And also we notice capacitive or resistive touch screen on any touch screen devices reviews...
then what is difference between CAPACITIVE TOUCH SCREEN AND RESISTIVE TOUCH SCREEN???
There are several touchscreen technologies available in the market these days. Out of them 2 are very popular with mobile phones and PDA’s . “Resistive” and “Capacitive” touch screen.
Resistive touchscreen are comparatively lower in price than active touchscreens. They are built with two flexible sheet coated with a resistive material and separated by microdots or air gaps. when pressed the sheets come in contact and register the contact location. Resistive technology works great with screens mostly used with stylus or any pointing object. But not very efficient in registering the pin point location when used with finger.
Capacitive touchscreen on the other hand is a glass surface coated with transparent conductors like indium tin oxide . As the human body is also a conductor, touching the screen with finger creates a electrostatic field, measurable as a change in capacitance. This location is then registered and action is made.
Most of the new touchscreen available in the market are now equipped with Capacitive touchscreen (pretty much all android and Apple phones).
iPad,iPhone,iPod, Android Phones,Nokia N97 and All New touch screens with multi touch have touch screens which are capacitive or something more superior than that.
In this generation, touchscreen mobile phones are the most popular gadgets used by most people for texting, calling and even for email and update our social media accounts by only touching the screen. But we have limited understanding on the type of touchscreen technology they have used in that smartphone or maybe tablet PC right now. Many touchscreen technologies are available in the market these days but there are 2 very popular for mobile phone touch screen technology are being used, the resistive and capacitive touchscreen. This blog explained the difference between the two. Resistive touchscreen has a 2 flexible layers coated with resistive material that separated by microdots or air gaps. We may use a stylus, our fingertips or any pointing objects, upon pressing or touching the top layer of the screen the 2nd layer contact and registered the input. On the other hand, the capacitive touchscreen has a surface glass coated with indium tin oxide (ITO). Our very fingertips can become a conductor running through touchscreen, so if we touch on the screen, it will register and command the function of a specific software application on that device.
