New Dynamic Iris realizes world's first* 5500:1 contrast ratio with a brightness of 1,100 lumens
for deeper, richer blacks
New Smooth Screen technology
Other LCD home cinema projectors can suffer from the
“chicken wire effect”—black lines between pixels that mar the
smoothness of the images. New Smooth Screen technology,
developed exclusively by Panasonic, virtually eliminates this
problem by providing the high contrast ratio and other
improvements that complement the new LCD panel of the PT-
AE900. Also, blurriness and flickering have been removed during
vertical panning, giving the PT-AE900 a sharp and detailed high-
definition picture that is remarkably smooth and realistic.

Cinema Colour Management technology
The colour correction system Cinema Colour Management
(CCM) was developed to enable free control of colours and has a
proven track record. Previously it had been difficult to reflect the
colourist’s intentions, because correcting one colour affected
certain others. With CCM technology, individual correction of
approximately 1,070,000,000 colours without affecting other
colours became possible. Colour control usually includes
control of contrast, but CCM technology goes even further and
controls brightness too. Incorporating CCM moves colour
correction closer to the process used for motion pictures.
Rendering deep, rich blacks is essential to faithful video
reproduction. With this in mind, Panasonic added further
refinements to the highly regarded Dynamic Iris with scene-
tracking capability for the PT-AE900. Using data obtained
from frame-by-frame histogram analysis of brightness,
digital image processing technology controls the light
intensity, iris, and gamma curve in real time. Now the iris
range of the new Dynamic Iris has been extended by about
60% compared to conventional models. This, combined with
histogram analysis employing algorithms for both brightness
and darkness, enables the PT-AE900 to render bright scenes
more brightly and dark scenes with deeper, richer blacks.
Histogram analysis can detect as many as 3,000,000,000
scene types. At the same time, Dynamic Gamma boosts the
brightness of picture details that would otherwise be
swallowed up in the dark portions. The contrast ratio has
been further increased by an optical system upgrade that
includes a new coating for the prism. The result of all these
improvements is the high contrast ratio of 5500:1 along with
the high brightness of 1,100 lumens. Enjoy the deep, crisp
blacks you've previously only experienced at the cinema.
