Improved contrast. The AE3000 was rated at 60,000:1, and the AE4000 is 100,000:1. Can you see the difference, you may wonder? Absolutely. When viewed in a dark room side by side, the AE4000 is obviously higher in contrast and deeper in black level than its predecessor. And with higher contrast comes the other typical benefits driven by contrast -- deeper color saturation, an improved sense of image depth, and the impression of increased image sharpness.

The improvement in contrast was not achieved by reducing the aperture on the auto iris. Rather, Panasonic has redesigned what they call the Pure Contrast Plate, an optical component located right after the LCD panels to improve the contrast level. This component effectively allows the polarization filters to block the light leakage caused from the panels, for deeper blacks.

As with the AE3000, the AE4000 uses inorganic LCD panels which also contribute to the higher contrast in these models. In inorganic panels, the liquid crystals are vertically aligned, making it easier for polarizers to filter out almost all light for deeper blacks.
