What is touchscreen? And how do it works?

What is capacitive touchscreen??…

In the cell phone industry there are two major categories of touchscreen displays: capacitive touchscreens and resistive touchscreens. Capacitive touchscreen displays rely on the electrical properties of the human body to detect when and where on a display the user touches. Because of this, capacitive displays can be controlled with very light touches of a finger and generally cannot be used with a mechanical stylus or a gloved hand. 

Examples of devices with capacitive touchscreens are the Apple iPhone and the T-Mobile G1. However, some modern displays like the Nokia Lumia 1520 are designed to support ultra sensitivity that can detect touches while gloves are worn.

What is Amoled?

AMOLED (active-matrix organic light-emitting diode, /ˈæmoʊˌlɛd/) is a touchscreen display technology used in smartwatches, mobile devices, laptops, and televisions. OLED describes a specific type of thin-film-display technology in which organic compounds form the electroluminescent material, and active matrix refers to the technology behind the addressing of pixels.
As of 2008, AMOLED technology was used in mobile phones, media players and digital cameras, and continued to make progress toward low-power, low-cost and large-size (for example, 40-inch) applications.
