ABSTRACT:
The system illuminates an active matrix EL device (AMEL) to provide a gray scale display. The device includes a first electrode layer comprising an active matrix of individually addressable pixel electrodes, a second electrode layer, and a thin film EL laminate stack including at least an EL phosphor layer and a dielectric layer. The stack is disposed between the first and second electrode layers. A first group of selected pixel electrodes are addressed with data signals during a first subframe time period where the first group includes fewer than all of the pixels electrodes of the display. The second electrode layer is driven during the first subframe time period with a first illumination signal. A second group of selected pixel electrodes are addressed with data signals during a second subframe time period where the second group includes only pixel electrodes not included within the first group. The second electrode layer is driven during the second subframe time period with a second illumination signal.
