Why does the Rainbow Effect happen?
At the core of most 1-chip DLP projectors is a spinning color wheel which can only display one color at a time. When these individual, one-color images are shown in rapid succession, our brain usually merges them into a single, unified image. However, a viewer may perceive flashes of these individual color images, creating the Rainbow Effect. According to projectorreviews.com, this is “...a ‘stroboscopic’ effect that has some people seeing flashes of red green and blue....”
3-chip 3LCD vs. 1-chip DLP
Unlike 1-chip DLP projectors, all Epson projectors use 3 individual LCD chips to generate red, green, and blue light that is projected simultaneously.
This technology eliminates the conditions that can create the Rainbow Effect, thus making 3-chip LCD projectors immune to that phenomenon.
