Abstract
A projector has a light source, a phosphor wheel, a digital mirror device (DMD) and a control unit. The phosphor wheel has a plurality of color sections. The light source projects a light source beam with a specific intensity onto a specific color section of the phosphor wheel when the DMD is operated at a specific duty cycle. By adjusting at least one of the specific duty cycle and the specific intensity, the control unit can adjust real brightness to approach specific target brightness of the specific color section so as to optimize white balance of the projector.
