Technology  Touch Panel
 
 
Definition
  • Touch Panel functions as a transparent switch which provides an easy access to generate electronic devices by touching illustrated images on a display.
 
 
Classification of Touch Panel based on Driving Mode
 
Resistive Touch Panel Capacitive Touch Panel
 
  • Resistive Touch Panel consisted of front and rear glass aligned between dot spacers detects the external touch transmitted from the ITO layer by sensing the pressure from electrodes.
 
  • Resistive Touch Panel delineates consecutive handwritings or small icons with a use of a tool or physical touch such as a stylus pen or finger.
 
 
 
 
Principle
  • Resistive Touch Panel detects a contact location from ITO coated glass by identifying an electrical signal from sensors of which measures the external force by sensing the change of pressure.
 
  Applications : Electronic Signature Pad, Automotive Navigation, PDA, Security Device, POS, Videophone, and so forth
