Abstract: A projection system includes a power supply device, a wireless charging transmission device, a projection system control assembly, a storage unit, and an optical system. The projection system control assembly controls a light valve thereof to convert illumination beam into image beam. A projection lens thereof projects the image beam to be a projection image. A user operation information is stored in the storage unit. The projection image includes an operation menu related to the user operation information. The projection system control assembly turns on or turns off the wireless charging transmission device according to the user operation information to wirelessly charge electronic device. A wireless charging method of the projection system is also provided.

Abstract: A projection device includes a light source, an optical engine and a controller. The light source provides a light beam according to a setting current. The optical engine includes a light combining module, an imaging module and a projection lens. The light combining module receives the light beam to generate an illumination beam. The imaging module includes a prism, a digital micromirror device and a light sensor. The prism transmits a portion of the illumination beam to the light sensor. The digital micromirror device converts the other portion of the illumination light beam into an image beam. The light sensor disposed between the prism and the digital micromirror device receives the portion of the illumination beam to generate a brightness data. The projection lens projects the image beam. The controller dynamically adjusts the setting current to calibrate a color point of the light beam according to the brightness data.
