Enhanced Dynamic Range with Advanced Optical System
A vast accumulation of Panasonic projector
technology is further strengthened by the
new Red-Rich Lamp and a refi ned, high-
precision optical system to enrich your home
theater experience.
New Red-Rich Lamp
The incorporation of the new
Red-Rich Lamp increases
the luminance effi ciency of
the projector, to achieve
150% brighter Cinema
Picture modes compared
to its predecessor, the PT-AE3000U. Prior
to the development of the Red-Rich Lamp,
much brightness was lost to attain the de-
sired color purity/balance for the rich color
reproduction of Cinema Picture modes due
to the lack of red luminance. The newly en-
gineered lamp successfully adds red lumi-
nance, and enables the projector to produce
brighter images with excellent colors. With
the ability to produce a stunning brightness
of 1,600 lumens, the PT-AE4000U unleashes
the beauty of full-HD expression for viewing
on various screen sizes.
Full-HD Optimized Optical System
To assure maximum clarity and sharpness
in full-HD images, this advanced optical sys-
tem employs a full-HD-optimized lens unit
comprising of 16 lens elements in 12 groups,
including two large-diameter aspherical
lenses and two high-performance ED (extra-
low dispersion) lenses. Each lens is care-
fully aligned to assure a
uniform focusing balance
from the centre to the
edges of the screen. As
a result, the PT-AE4000U
produces stunningly clear
Large-diameter as-
and beautiful images.

New Pure Contrast Plates Deliver High
100,000:1 Contrast Ratio
The Pure Contrast Plates in the PT-AE4000U
use a newly engineered crystalline material
that is carefully matched to the character-
istics of the LCD panels to effectively correct
the passage of light exiting the panels. This
enables the projector to block unwanted light
leakage and successfully increases the dy-
namic range. It works together with the dy-
namic iris to achieve an astounding contrast
ratio of 100,000:1.
Pure Color Filter Pro for Rich, Vibrant
Colors
The optical fi lter optimizes
the light spectrum from
the UHM projector lamp,
helping to produce deeper
blacks while improving
purity levels in the three

primary colors (red, green and blue). This
advanced fi lter system improves color purity
to cover a range that extends from the HDTV

. This gives images
the deep, rich coloring that distinguishes
movie images.
Smooth Screen Technology Creates
Film-Like Texture
While many LCD projectors suffer from a
"chicken wire" effect, Panasonic's pursuit
of the highest possible image quality has
successfully overcome this device limitation
through the incorporation of Smooth Screen
technology. This uses the double refraction
property of crystals to arrange pixels on a

Screen technology is designed to give you the
kind of smooth, vivid, and three-dimensional-
like images you see in movie theaters.
Dynamic Iris Adds Beauty to Both Dark
and Bright Scenes
The fifth generation intel-
ligent iris system works by
analyzing the brightness
level of each image using
a histogram, then adjusting

accordingly
to create the ideal image. The adjustments
are made virtually frame by frame. This helps
the projector achieve a wide dynamic range
with swift smoothness for added beauty in
both dark and bright scenes.
Full-HD LCD Panels Enhance Motion
Response
The PT-AE4000U's full-HD LCD panels have
a double-speed drive capability that improves
the projection clarity of moving images. These
high-precision panels use vertically aligned
liquid crystal molecules with inorganic align-
ment layers. When no voltage is applied, the
molecules are aligned perpendicular to the
glass substrate, so there is minimal light
leakage and the substrate remains black
(called "normally black" operation), providing
higher contrast.
