Capacitive Touch Screen Technology


Capacitive touch screen technology is a popular and durable technology that is used in a wide range of applications. It has a higher clarity than resistive technology, but it only responds to finger contact and will not work with a gloved hand or pen stylus. A capacitive touch screen consists of a glass panel with a capacitive (charge storing) material coating its surface. Circuits located at corners of the screen measure the capacitance of a person touching the overlay.


Capacitive touch screen technology is often recommended to customers who would like the confidence of a brand name LCD such as NEC, which the capacitive touch screen would then be retrofitted to.

Limitations of capacitive touch screen technology:

  • Can not be used with a gloved hand
  • Can not be used with stylus
  • Requires periodic recalibration
  • Often retrofitted to standard non-touch LCD monitors which may not be as stable when touched
  • Not usually fitted to monitors when applications require dust, water, scratch or impact resistance

Popular Brands that often use capacitive touch screen technology:

  • 3M Microtouch
