<p>A position sensing display integrates a touch sensor with an active matrix LCD panel. The panel includes both coarse (12) and fine (4,6) sensing means. The fine sensing means includes fine sense electrodes combined together in groups, the groups being interdigitated i.e. alternating across the display. In use, the fine sensing electrodes determine the position of a sensed object such as a stylus or finger accurately but non-uniquely, and the coarse sensing means determines which of the plurality of non-unique positions is correct.
