Capacitive Touch VS. Resitive Touch

Capacitive touch screen:

Pros:
  • Multi touch support available
  • Visibility good even in sunlight
  • Highly sensitive to finger touch leading to ease of use
  • Not prone to dust particles
  • Glossy look and feel
Cons:
  • Need to have atleast 5% humidity to achieve capacitive effect
  • More expensive than Resistive touch screen
  • Doesn't work with inanimate objects/fingernails/gloved fingers
  • Latest technology, may need to evolve a bit more!

Resistive touch screen:

Pros:
  • Relatively cheaper
  • Can operate with any pointing devices like stylus, pen, nail etc
  • Can operate at any level of humidity
  • Ease of use, as it could be used even with your winter gloves on!
  • Very useful for people using handwriting recongition system, due to ease of use with a stylus!
  • More accurate than capacitive touch screen!
  • Old technology and hence more reliable!
Cons:
  • Multi touch support not available. Though technology did evolve after some modifications with the existing resistive touch screen circuitry, its still not 100% developed yet!
  • Highly sensitive. As it can operate with almost any sort of pointing devices, can be more vulnerable with dust particles!
  • Poor visibility in sunlight, mostly due to multiple layers reflecting light!
  • Screen, being sensitive at the upper layer, can be more vulnerable to scratches!
