Touch Screen:
Basically there 2 types of Touch Screen phones
1.Resistive Touch Screen
2.Capacitive Touch Screen

>>The basic difference between the two is in the way they respond to the touch of your finger
>>The way they respond to the touch of your finger or stylus.

1.Resistive Touch Screen
           Resistive touchscreens work on the basis of pressure applied to the screen. A resistive screen consists of a number of layers. When the screen is pressed, the outer later is pushed onto the next layer — the technology senses that pressure is being applied and registers input. Resistive touchscreens are versatile as they can be operated with a finger, a fingernail, a stylus or any other object.

2.Capacitive Touch Screen
               Capacitive touchscreens work by sensing the conductive properties of an object, usually the skin on your fingertip. A capacitive screen on a mobile phone or smartphone usually has a glass face and doesn't rely on pressure. This makes it more responsive than a resistive screen when it comes to gestures such as swiping and pinching. Capacitive touchscreens can only be touched with a finger, and will not respond to touches with a regular stylus, gloves or most other objects.


==>Though resistive touchscreens are often quite responsive — especially in many new smartphones hitting the market — capacitive touchscreens usually provide a more pleasant user experience. Actions like swiping through contact lists, zooming in and out of Web pages and maps, typing e-mails and text messages and scrolling through photos are best suited to capacitive touchscreens; unlike resistive screens, you can swipe across them gently and still get a response. Resistive screens are often found in cheaper devices, as they cost significantly less to manufacture.

The foremost reason for the two touchscreen technologies to differ when used is the way they respond to your fingers command. Whether you press, poke or prod, the touchscreen will follow the input as per the technology inside. The Resistive technology simply works by sensing pressure.

To understand more about the this technology, you need to peel off its layers literally. In short, the resistive touchscreen is made up of several layers. When compressed, the first layer passes the sensation to the next layer. The top most layer when pressed passes on the vibe no the layer beneath it. This chain sequence completes a circuit, thus helping the phone know which part of the screen is being pressed.

On the other hand, the capacitive touchscreen works in a different way. It doens't rely on the pressure of the finger, rather the capacitive touchscreen uses electrodes to sense the conductive properties of objects, such as your finger. It simply means that a capacitive touchscreen device may very well understand the command by your finger but not that of a stylus. So, you won't be able to get any desired action on these devices if you prod it with any pointed objected.

To help you understand more, we have selected some popular smartphone devices that come equipped with capacitive or resistive touchscreen technology. In the table below, you can very well figure out which sort of touchscreen the devices available in the stores use. In fact, we have categorized them on the basis of the popular operating systems used on the smartphone as well for your ease.


Resistive vs capacitive

Resistive touchscreens are made of several layers, the topmost of which flexes under your finger or stylus, and is pushed back to touch a layer below it. This completes a circuit, telling the phone which part of the screen is being pressed.

Capacitive touchscreens don't rely on pressure, and instead use electrodes to sense the conductive properties of your finger. So they don't rely on having an object pressing particularly hard on their surface, and react only to touch of your finger.
