Optical Engine - Epson EMP-TW1000 Service Manual

2.2 Optical Engine

The optical system consists of four components: the Lamp Unit, the Light Guide Unit, the
Panel-on-Prism (POP) Unit, and the projection lens. These four components together are called
the Optical Engine. This projector is equipped with the D6 series light valves using the brand-
new high-quality picture technology "Crystal Clear Fine (C
Features of D6 series (hybrid driving technology)
The hybrid driving technology enables downsizing of the driver circuit board by mounting
the horizontal driver IC and LCD driving controller IC on the FPC of each light valve
(Since the ICs with superior driving capabilities are used on the FPCs, only one controller
IC is used on the new circuit board. (16-18 ICs on the board of a conventional model.))
Along with this feature, the following is achieved.
1).Improved writing characteristics
The superior driving ability of ICs considerably reduces the variance in writing
characteristics onto pixels. Consequently achieved uniform writing to all the pixels
produces smoother images.
2).Low power consumption
Power consumption of the panel driving system is highly reduced. (Only about 10 % of
power consumption compared with a conventional EPSON 1080P panel.)
Features of "Crystal Clear Fine (C
• Adoption of inorganic LC alignment layer reduces unevenness of molecular orientation.
Improved evenness realizes smoother images.
• Use of vertical alignment technology achieves high contrast.
• Along with the above technology, adoption of the normally-black mode realizes jet-black
reproduction.
