4. Main Components / Functions
1. Touch screen
• Principle : voltage (電壓) is applied at each screen corner -> draw current to the
contact point when fingers touch on the screen -> calculate coordinates of
pressurized area -> produce outputs
• Much more user-friendly because touch screens give out more direct and immediate
responses to users than feature phones (with only 12 keys)

6. Main Components / Functions
3. Fingerprint Recognition
• Fingerprint-sensor technologies : optical readers and capacitance readers
• Optical readers take a picture of your fingerprint with a camera (less complicated)
• Capacitance readers measure the difference in electrical conductivity caused by
the raised parts of your fingerprint (complicated but more secured)
• Commonly used in :
Unlocking the phone
