The Red and Blue pictures are illuminated, in turn, by dedicated LEDs.
The 3LCD advantage
After Sony's laser and phosphor wheel, the remaining optical engine is largely based on
Sony's proven VPL-FH30 projector. This means the VPL-FHZ55 reaps all the benefits of
Sony's 3LCD system. And the FHZ55 goes further with a refined version of Sony's BrightEra®
LCD microdisplay.
In the 3LCD system, a pair of dichroic mirrors separates white light into Red, Green and Blue
beams. These pass through the LCD microdisplays, which reproduce the Red, Green and
Blue components of the video picture. These Red, Green and Blue components immediately
pass into an optical prism, which fuses them into a unified, full-colour image.
