COMPUTER FUNDAMENTALS

Detailed explanation-1: -Tablet PCs, smartphones, and all-in-one computers are examples of input devices using a capacitive touch screen. A glass layer that resembles an insulator and is covered in a transparent conductor, such as indium tin oxide, makes up the capacitive touch screen (ITO).

Detailed explanation-2: -Capacitive Touch Screens These screens have three layers: a glass substrate, a transparent electrode layer and a protective layer. Their screens produce and store a constant small electrical charge or capacitance. Once the user’s finger touches the screen, it absorbs the charge and lowers the screen capacitance.

Detailed explanation-3: -Mainly we use two types of glass in TFT LCD displays, one is chemically strengthened glass, that we call CS type glass, the other is thermally tempered glass, hardened glass where we use hot temperature to make it stronger. For our standard products we typically use on the touch screens chemically strengthened glass.

Detailed explanation-4: -Touchscreens work using electricity. The screen is made of glass, an insulating material – it cannot carry an electric current. The surface of the screen is therefore coated with a thin layer of an electrically conducting material such as indium tin oxide. This is chosen because it is transparent.
