large interactive touch screen monitors.Surface-capacitive ITO coatings usually require linearized metal electrodes on the periphery of the screen to reduce the effect of corner / edge effects on the electric field. Sometimes there is an ITO shielding layer under the ITO coating to block noise. Surface capacitive touch screens need to be calibrated at least once before they can be used.
