A power-saving method with integrated photodiode light source. This device has a circuit board with a plurality of red, green and blue photodiodes as the device's light source. Additionally, a light control circuit is used to control light beam from the light source illuminating a reflector and then reflecting to a reflective display panel in order to reflect the light beam and generate an image. Thus, a projection module can project the image on a viewing plate. As cited, the inventive device includes: a light control circuit, a light source module, a polarizing beam splitter (PBS), a reflective display panel and a projection module.
