Leading touch technologies used in mobile phones are
1. Resistive Touch
Resistive touch screens are composed of two flexible sheets coated with a resistive material and separated by an air gap or microdots. When pressure is applied to the screen, by a finger or other objects, the sheets are brought into electrical contact whichcauses a switch closure and a command is registered.2. Capacitive Touch
Resistive Vs Capacitive Touch Screens
Clarity
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.
Responsiveness
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.
Durable
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.
Usability
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.
Versatility
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.
Price
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.
Multi-touch
In resistive touch there is no possibility of multi touch. Recently Nokia has delivered Multi-touch in resistive touch screen, All high end Capacitive touch devices will support multi-touch.
