Abstract
Crosstalk is reduced in any type of active matrix electro-optical display system (10) by applying a compensating signal, the value of which is dependent upon multiple data drive signals. In a preferred embodiment, a single compensating signal, equal to the inverse weighted average of all of the data drive signals applied during a row address period, can be applied to all data electrodes (20) after the data drive signals are stored in display elements (16). Such a compensating signal simultaneously reduces side-to-side crosstalk and front-to-back crosstalk to levels previously achievable for only one type of crosstalk at a time.
