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.
