Abstract
A reflector applied in a projector including a projection control circuit, a light source unit, a beam combiner, and a lens is disclosed. The reflector includes a transparent electrode layer, an electrophoresis layer and a pixel electrode layer. The electrophoresis layer includes a plurality of micro cups, each micro cup contains suspension therein and a plurality of charged particles. The pixel electrode layer includes a plurality of pixel electrodes corresponding to the micro cups. The projection control circuit provides voltages between each pixel electrode and the transparent electrode layer to drive the charged particles to migrate. When the charged particles arrive at the transparent electrode layer, the lights from the light source unit are reflected by the charged particles to the beam combiner to be combined into an image to be transmitted to the lens to project an image.
