Projector and reflector thereof

A projector comprising:

• a projection control circuit;
• a light source unit to emit a plurality of colored lights;
• a beam combiner;
• a lens;
• a reflecting unit comprising a plurality of reflectors, each of the reflectors being correspond to one colored light emitted by the light source unit and being controlled by the projection control circuit to reflect the colored light, each of the plurality of the reflectors comprising:
• a transparent electrode layer;
• an electrophoresis layer comprising a plurality of micro cups arranged in a matrix, each of the micro cups comprising suspension therein and a plurality of charged particles dispersed in the suspension;
• and
• a pixel electrode layer comprising a plurality of pixel electrodes, each of the plurality of pixel electrodes corresponding to one of the micro cups, the electrophoresis layer being electrically connected between the transparent electrode layer and the pixel electrode layer;
• wherein, the projection control circuit is to provide voltages between each pixel electrode of the pixel electrode layer and the transparent electrode layer of each reflector to drive the charged particles to migrate to the transparent electrode layer;
• when the charged particles arrive at the transparent electrode layer, the lights from the light source unit are reflected by the charged particles, the beam combiner is to combine the lights reflected by the reflectors into an image and then the image is transmitted from the beam combiner to the lens to project an image.
