Abstract

A projection system includes projection devices and a control device. Each projection device is configured to provide first, second, and third light beams of different wavelengths. The projection devices include processors and light valves. The processors include first, second, and third processors. The light valves include first, second, and third light valves. Each of the processors is connected to one of the light valves. The control device respectively provides first, second, and third signals to the first, second, and third processors. The first, second, and third processors respectively control the first, second, and third light valves to provide the first, second, and third light beams in turn according to the first, second, and third signals, so as to generate an image beam; in the same time sequence, the light beams provided by the first, second, and third valves controlled by the first, second, and third processors have different wavelengths.
