Touchscreen Technology

Touchscreens are an electrical visual display that can defect the presence and location of a touch within the display area. The term generally refers to touching the display of the device with a finger or hand. Touchscreens can also sense other passive objects, such as pens/ stylus. 

The touchscreen has two main attributes. Firstly, it enables the user to interact directly with what is displayed, rather than having to use a mouse, stylus or touch-pad. Secondly, it allows one to interact with the display n the screen without requiring any intermediate device that would need to be held in the hand. Such displays can be attached to computers, or networks as terminals. They have gradually evolved from the stylus and screen setup and now play an prominent role in the design of appliances such as the personal digital assistant (PDA), satellite navigation devices, mobile phones, and video games, MP3 players ATM's etc.

Touchscreens are now very popular and successful in the digital world, and are still improving. The latest touchscreen technology can be found in appliances such as the iTouch, iPhone and iPad. These products are especially successful.
