Abstract:
The invention relates to a method of electronic contrast enhancement for an LCD panel for use in an imaging device. The method comprises the step of coupling the LCD panel with a trim retarder in a pre-determined azimuthal orientation for at least partially compensating the residual in-plane retardance, followed by the step of non-mechanical fine-tuning of a dark state of the LCD panel. In the preferred embodiment, the fine-tuning of the dark state of the LCD panel is realized by adjusting the dark-state magnitude of the LC voltage. The method can be used in batch, e.g. wafer-level manufacturing of integrated trim retarder/LCD panels assemblies that can be electronically tuned to provide high on/off contrast.
