Abstract
A dual and/or multi modulator display system is disclosed comprising at least a first modulator and a second modulator wherein one of modulators has a faster response time that the other modulator. The response of the slower modulator may be characterized according to various image data inputs and this characterized data may then be used by the display system to derive control and/or data signals to the faster modulator. These control/data signals may represent a fitted set of data matched to one or more characteristics of the slower modulator in order to reduce light produced during frame or other transition times of the modulators. One or more characteristics may be employed to reduce such undesirable visual effects.
