Touch input is a technology that is widely used today in almost all electronic devices right from mobile phones to tablets and personal computers. Touch sensitive display is offered in two variants today – Capacitive and Resistive.
Resistive touch screens consist of two resistive materials with an air gap in between them. Touching the screen causes the two materials to come closer, which is then detected as an input by the electronic device. Resistive touch screens are somewhat cheaper when compared to capacitive ones. Moreover, a resistive touch screen can sense the touch not just from a palm or a finger, but also from stylus like objects as the sensing is just dependent on the pressure applied on the screen.
Capacitive touch screens use a different technology in sensing touch than a resistive screen. These screens use electrodes to sense the touch of an object that simply has the dielectric value different than that of air. This gives the capacitive screens a slighter edge with respect to sensitivity of the screen. Even a small swipe by the tip of a finger is enough to generate a response whereas its counterpart requires a heavy touch to get the necessary response.
By the looks of it, one might be captivated to go towards a capacitive screen but resistive screen also scores higher in certain aspects. One is that it’s definitely a cheaper technology thus making it possible for Nokia to manufacture its low end touch phones (with pricing as low as 4,500 INR). Due to the fact that resistive screens operate on the basis of a different technology, it is not required for a resistive screen to be touched solely by a bare finger. Even a stylus or any pointed objects for that matter work. But that isn’t so for a capacitive touch screen. As a matter of fact, capacitive screens rely on a bare finger to detect a conductivity difference between the screen and it to take the input successfully. This makes it impossible to use them with gloved fingers or a traditional stylus albeit a conductive stylus can be used to overcome this problem.(Samsung Galaxy Note is shipped with such a stylus that can be operated upon capacitive touch screens). Resistive screens are better in terms accuracy when compared to capacitive screens, which can give a first time user a horrid time, especially when trying to scroll up or down.
Conclusion:Resistive touch screens are less sensitive and cheaper than capacitive but can sense the touch not just from a palm or a finger, but also from stylus like objects as the sensing is just dependent on the pressure applied on the screen. But if you are well situated to using your bare finger, then capacitive screens shouldn’t pose you any kind of problems since they respond pretty well even to the slightest of touches.
