Resistive vs Capacitive touchscreen

Touch screens are most often used these days. Those were the most interactive interfaces for small-sized Gadgets and Accessories.

These were classified into various kinds depending on the technology they are using.

1. Resistive
2. Surface acoustic wave
3. Capacitive
4. Infrared
5. Optical imaging
6. Dispersive signal technology
7. Acoustic pulse recognition

However, the most common and widely available ones are Resistive and Capacitive. Here are the differences between them.

	Resistive	Capacitive
Comprehension	Two different flexible electro-resistive sheets are used to achieve this. One is placed above the original LCD Display and the other is placed over the first one and both the sheets are separated by an air gap. A voltage is applied to one of the layers.	An insulator such as glass is placed over LCD Display and the insulator layer is coated with a transparent conductor. A small voltage is applied to the transparent conductor to create an electrostatic field.
How they work	When we touched the screen with the stylus, the two electro-resistive layers are brought into touch producing the electronic signal and the resultant signal will be handled accordingly by the gadget.	Since the human body is also an electrical conductor, touching the insulated layer results in electrostatic-distortion which is measured as capacitance. And the capacitance will be handled accordingly by the gadget.
Advantages	Low Cost of manufacturing Works with Stylus, Gloves, fingers and almost all apparatus. It can be used to create drawing pads, sketch pads, etc as the stylus will be sharp enough to draw thin lines.	No Reduction in contrast or brightness Works Great with bear fingers. It can be used for smartphones, tablets, etc. Best for games as the touch is very quick and smooth
DisAdvantages	Reduction of Contrast as well as brightness. (Due to the reflections between two layers and the reduction can be less when the gap between them is less) As we can use almost all sharper objects they Have a danger of breaking the screen. Touch will always be difficult as we must press it hard to produce a contact between two layers. Not good for games as the touch will be delayed and we’ll lose.	High Cost of manufacturing One cannot use objects like Gloves, Stylus. (A special conductive stylus should be used if needed) Touch will be a bit difficult when the weather is cold (due to the wrinkles formed on fingers) It will not be easy to draw thin lines when using it on drawing and sketch pads. (But some applications can handle this issue)
