HD Compatible Lens System and
New Optical Engine
The lens system plays a key role in getting
the best images possible from full-HD
video sources. To assure outstanding
quality in the new PT-AE1000E, Panasonic
developed a full-HD-compatible lens unit
comprising 16 lens elements in 12 groups,
including two large-diameter aspherical
lenses and two high-performance ED
(extra-low dispersion) lenses. We also
developed a “Clear Prism” to process the
three primary colours (red, green and blue)
that create the image. By controlling the
diffused reflection within the projector, the
Clear Prism reduces the chromatic
aberrations that can cause colour deviation.
The result is a sharp, high-contrast image
all the way to the edges. This sophisticated
new lens system contributes to the
PT-AE1000E’s remarkable 11,000:1
contrast ratio. Next-Generation Full-HD LCD Panels
The PT-AE1000E is equipped with next-
generation full-HD LCD panels*
1 . With their
native 1,920 x 1,080 resolution, these
panels are ideal for reproducing beautiful
full-HD images. The panels use inorganic,
vertically aligned liquid crystal molecules.
When no voltage is applied, the molecules
are aligned per-
pendicular to the
glass substrate,
so there is no
light leakage and
the substrate
remains black
(called normally
black operation).
Dynamic Iris
The Dynamic Iris helps provide the deeper,
richer blacks you need for true-to-life
images. This system works by analysing
histograms to determine the brightness
level of each image, then adjusting the
lamp power, iris and gamma curve*
2
accordingly to create the ideal image. The
adjustments are made 60 times every
second. In the PT-AE1000E we used a new
algorithm that further improves response
and stability. It helps the projector achieve
a wide dynamic range, with beautiful
display of both dark and bright scenes.
