| The incorporation of the new
Red-Rich Lamp increases
the luminance efficiency
of the projector, to
achieve 150% brighter
Cinema Picture modes compared
to its predecessor, the PT-AE3000. Prior to the development of the Red-Rich Lamp, much brightness was lost to attain the desired color purity/balance for the rich color reproduction of Cinema Picture modes due to the lack of red luminance. The newly engineered lamp successfully adds red luminance, 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-AE4000 unleashes the beauty of full HD expression for viewing on various screen sizes. |

| To assure maximum clarity and sharpness
in full HD images, this advanced optical system
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 (extralow
dispersion) lenses. Each lens is carefully aligned to assure a uniform focusing balance from the center to the edges of the screen. As a result, the PT-AE4000 produces stunningly clear and beautiful images. |

| The Pure Contrast Plate in the PT-AE4000 uses a newly engineered crystalline material that is carefully matched to the characteristics 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 dynamic range. It works together with the dynamic iris to achieve an astounding contrast ratio of 100,000:1. |
The optical filter 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 filter system improves color purity to cover a range that extends from the HDTV standard (Color 1 mode)*1 to the color gamut used in digital cinema*2. This gives images the deep, rich coloring that distinguishes movie images. *1 A setting that supports the 6,500K color temperature
recommended in the HDTV standard (ITU-R BT.709) |

| 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 with no gaps between them. Smooth Screen technology is designed to give you the kind of smooth, vivid, and three-dimensional like images you see in movie theaters. |

The fifth generation intelligent iris system works by analyzing the brightness level of each image using a histogram, then adjusting the lamp power, iris and gamma curve* 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. * Parameters for adjusting the output brightness gradation level according to the input signal. |
| The PT-AE4000'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 alignment 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. |
