1. A method of operating a display, the method comprising:
- applying a voltage difference across a first display element based on a first voltage level indicative of a portion of an image; and
selectively applying a current indicative of the portion of the image across a second display element based at least partly on the first voltage level and based at least partly on a second voltage level,wherein the voltage difference is applied so that the first display element substantially absorbs incident light when the current is below a specified level and reflects light when the current exceeds the specified level.

Abstract
One embodiment includes display comprising a light modulator configured to display a portion of an image such as a reflective light modulator, a light emitter configured to display the portion of the image and a circuit configured to selectively provide signals to at least one of the light modulator and the light emitter indicative of the portion of the image. In one such embodiment, an active matrix provides a simple, efficient drive for such devices. Other embodiments methods of making and driving such devices.
