There are two technologies used in the majority of all projectors: 1-chip DLP and 3-chip 3LCD.
All Epson projectors use 3-chip 3LCD technology because they offer power-efficient projection that delivers bright, true-to-life images. 3LCD projectors have high colour brightness as well as high white brightness. 1-chip DLP technology uses a spinning colour wheel to render colour which produces a lower colour light output than 3LCD technology. 3LCD engines have no colour wheel, and therefore, so there are no tradeoffs between white and colour brightness.
