One  key  to  enhancing  picture  quality  is  black  reproduction.  Panasonic 
developed  the  new  Dynamic  Iris,  with  an  expanded  iris  range,  and  a 
new  optical  block  to  give  the  PT-AE900  deeper,  richer  blacks  than 
earlier  home  cinema  projectors  provided.  By  substantially  expanding 
the  dynamic  range  available  for  expressing  images,  we  achieved  a 
contrast  ratio  of  5500:1  along  with  the  brightness  of  1,100  lumen. 
What's  more,  new  Smooth  Screen  technology  combined  with  a  new 
LCD  panel  allows  the  projector  to  reproduce  smoother,  more  natural 
looking images.
All  this  hard  work  paid  off.  Today  the  PT-AE900  is  recognized  as  a 
cinema projector suitable for professional video reproduction. It is even 
used as a reference monitor on some movie sets.
New advanced technologies deliver the true 
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.  Using  data  obtained  from  frame-by-frame 
histogram  analysis  of  brightness,  digital  image  processing 
technology controls the lamp power, iris, and gamma curve every 
1/60 second, the industry’s fastest. 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.
