Advanced Plasma TV Technologies Pioneer developed Crystal Emissive Layer technology to achieve deep black reproduction, and for our latest plasma panels, we've made it even better. We also refined the structure of the light emitting cells and employed a new electron source material to speed up the discharge rate in order to prevent spark discharge during black reproduction. As a result, we succeeded in reducing the minimum brightness to one-fifth of previous models. This enables the highest contrast ever achieved in the industry, so you can enjoy truly a vibrant and natural picture, even during dark scenes. 　New Direct Colour Filter The colour filter is also a key element determining picture quality. Pioneer's proprietary high performance filter, the New Direct Colour Filter, effectively reduces reflections, ensuring solidblacks, optimum contrast and brilliant colours regardless of the light conditions -- from bright sunlight to dark home theatre rooms. It also cuts annoying glare. All Pioneer PDP models use New Direct Colour Filters that provide enhanced chromatic purity for superior colour reproduction. 　Deeper Blacks Mean More Vivid Colours When blacks are deep and solid, colour reproduction also improves, with colours standing out sharply and brilliantly. Even at low brightness levels, the three primary colours of red, green, and blue are deeply and vividly produced, meaning that in night-time or shadowy scenes, colours will stand out beautifully without being assimilated into the darkness.
