This presentation gives a brief insight to the world of Touch Screen Technology. Every common man in the 21st century is bounded by this ground breaking revolution in the digital world, yet only a countable number of them is fully aware of this vast topic in details. This presentation is a small step to enlighten people of the technology which they use in their day to day life.

3. TOUCH SCREEN TECHNOLOGY
Four different technologies used to make touch screens today:
Resistive
Capacitive
Surface Acoustic Wave (SAW)
Infrared LED or Optical
4. RESISTIVE SYSTEM
Consists of a glass panel with two layers,
conductive and resistive metallic layers
Electrical current runs between both layers when
operational
The two layers make contact when touched,
sending coordinates to the driver
11. CAPACITIVE SYSTEM
One layer that stores electrical
charges on the panel
When touched with a finger, the
electrical charge is transferred to user
Computer then coordinates where
touch took place
