Resistive Vs Capacitive Touch Screen

No doubt touch screen is the making it nice rapidly in the field of technology. A device with touch screen is preferred as compared to the device without touchscreen. Everything with a display is now changed into touch display like watches, monitors, laptops, iPhones, MP3s; whatever you think with a display is available in touch screen mode.

Touchscreen is not only single module. There are different types of screens available in market whose touch mechanism is different from one another. Most known touch screen are two types and here we are supposed to discuss the comparison and contrast between the two. It is better to have enough knowledge about two of them so that we should be aware enough to make a right choice according to our demand.

These two types are Resistive and Capacitive touch screens.
Here are the Similarities and Dissimilarities between two types of touchscreens depending upon its various features;


General appearance of both types is same as both are used for display. While seeing them in off-mode there seem no particular difference.


Display of both types is available in various sizes but resistive has been even more versatile than capacitive. For example a projector with capacitive touchscreen is not as effective as of resistive touchscreen because our hand does not reach some of the areas on projector which are higher than our height.


Resistive touchscreen is Pressure sensitive while Capacitive touchscreen is HID (Human Interface Device or responsive to the conductive material. When we apply pressure on resistive touchscreen they strike because of the space between two layers and locate the point of touch to carry out the desired command while outer layer on the glass protect the screen from damaging its mechanism.


Capacitive touchscreen is made of capacitive layer with static charge. So glass panel in capacitive touchscreen is more exposed as compared to resistive touchscreen. Now see, resistive layer is made up of three layers so restrict the full emission of light (75 %) from screen which results into bulky image. On the other hand capacitive screen emits 90 % of light as there is only one layer. In short, capacitive touchscreen gives clearer image than resistive touchscreen.


Capacitive touchscreens are more responsive than resistive touchscreens. Pressure applies by different personae make its mechanism weak and with the passage of time it needs more pressure than normal.


Resistive touchscreen is durable than capacitive. Directly expose, the glass panel of touchscreen starts damaging while resistive touchscreens are made up of three layers which helps to protect the glass panel and therefore durable.


Resistive touchscreen is easy to use as it can be operated with any object in hand like stylus etc. But capacitive touchscreen is only operated by finger ouch because it is human interface device. Therefore it is not prefer to use at higher level where stylus is desired to use. Capacitive touchscreen is not responsive to stylus, gloves or other object. It just senses finger touch or an object made up of conductive material.


Touchscreen devices are in demand so are making in variety of range. Here again resistive touchscrens are available in wide rang because of its durability and easy to use but capacitive touchscreen devices like mobiles, laptops and watches are gaining much popularity.


When it comes to the price, capacitive win the race but winning this race loses its niche. People prefer to go for comparatively less expensive resistive touchscreen mobile or whatever they want to purchase.

A comparison of both types of touchscreen is before you, now it’s up to you which medium you like or prefer to purchase. Presently accessories are introducing with capacitive touchscreen so there is no doubt that if not the whole horizon even then for intimate use capacitive is gaining its niche in the future market.
