Touch sensitive display

摘要

A touch sensitive display comprises pixels ( 18 ), each of the pixels ( 18 ) have a pixel electrode ( 22 ). An optical state of a pixel ( 18 ) depends on a drive voltage (VD) supplied to the pixel electrode ( 22 ). A touch sensitive elements (S 1 ) is arranged between the pixel electrode ( 22 ) and a further electrode ( 40;17 ). The touch sensitive element (S 1 ) has an impedance dependent on a mechanical force applied to it.
