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
