Abstract
There is provided a projection system that includes a light source, a display panel, a projection optical system, and a controller. The light source outputs light of a plurality of colors. The display panel includes a light modulation element provided for each pixel, and modulates the light outputted from the light source. The projection optical system projects light having passed through the display panel, and the controller controls light output of each color of the light source in a time-axis direction. This configuration is adopted to achieve an improvement in brightness of a projected image/a screen and prevention of color mixing in field sequential driving.
