SVGA LCD PROJECTOR

10.1
SLB - SMALL, LIGHT AND BRIGHT
The projector was designed to be the ultimate portable projector.
The advanced, miniaturized optical design and the use of a relatively low
power, high efficiency illumination system combined with optimalized
electronics has yielded a very compact, lightweight projector.

AUTOMATIC SETUP
The projector always seeks to adjust the projected image automatically. The
user may also at any time invoke the autoadjust function by pressing
RESET. When auto is operating, the image will be shifted to different
positions on screen for about 5 seconds before it is stabilized.

POLYSILICON TFT LCD TECHNOLOGY
The light valve technology employed in the projector is based on small TFT
(Thin Film Transistor) LCDs (Liquid Crystal Displays) manufactured in a
high temperature process enabling the formation of so called PolySilicon
transistors. These transistors are used both as switching elements at each
picture element (pixel), and for other electronic signal handling.

BASIC OPTICAL SYSTEM
The projector is based on three PolySilicon TFT LCD light valves, one each
for the primary red, green and blue colors of the spectrum. Any other color
may be produced by combining various amounts of these primary colors.
High brightness is made possible by novel techniques for improved light
collection in the illumination system and better distribution through the
optical system. A special PBS (Polarized Beam Splitter) is employed to
reduce the traditional loss of light that is normally associated with LCD
systems using polarized light.
