Title:
PROJECTION SYSTEM AND PROJECTION METHOD APPLIED TO PROJECTION SYSTEM
Document Type and Number:
Japanese Patent JP2023070163
Kind Code:
A
Abstract:
To provide a projection system and a projection method.SOLUTION: A projection system includes projection devices and a control device. Each projection device is configured to provide first to third light beams of different wavelengths. The projection devices include processors and light valves. The processors include first to third processors. The light valves include first to third light valves. Each of the processors is connected to one of the light valves. The control device respectively provides first to third signals to the first to third processors. The first to third processors respectively control the first to third light valves to provide the first to third light beams in turn according to the first to third signals, so as to generate an image beam; in the same time sequence, the light beams provided by the first to third light valves controlled by the first to third processors have different wavelengths. According to the present invention, the projection system can reduce a rainbow effect on a projection screen.SELECTED DRAWING: Figure 1
