The new 50-inch PDP5080XD
Plasma displays take another revision for the high-end

This week high definition TVs based on plasma technology receive a big boost in quality and performance thanks to newly developed technology by Pioneer. One of the primary concerns these days with flat panel TVs -- and other displays for that matter -- is the ability to produce rich, deep and dark blacks. LCDs have always had a problem with blacks as their backlights are on all the time as long as the display is turned on.

Since the battle between LCDs and plasmas started, plasma screens always held an edge over LCDs because each pixel on a plasma screen is self emitting, generating its own light. Despite this, many plasma screens still produce black levels that are off due to low grade electronics and other factors. Pioneer is introducing what it calls the eighth generation plasma TV, giving audiences blacks that are 80% darker than anything currently available.

Using what Pioneer calls "deep encased cell structure, crystal emissive layer and first surface color filter," its new screens boast a contrast ratio of 20,000:1.

According to Pioneer, "with significantly deeper black levels (80% deeper than before), which ultimately lead to richer colours and sharper details, the new screens are unrivalled in video and audio performance."

Pioneer will be featuring the new ultra black technology in a series of TVs it calls "Project KURO" -- kuro meaning "black" in Japanese. The lineup will include 42, 50 and 60-inch screen sizes supporting full 1080p resolutions. As of right now, no prices have been revealed and Pioneer only indicates that the new units are "coming soon."

LCD panels will soon receive a major change themselves in the form of LED backlighting. Apple announced earlier last week that all of its LCD screens will be based on LED backlight panels by the end of 2007.

Pixel pitch is a function of the ratio between native resolution vs. panel size; it's not dependent on image technology. A 50" 1080p panel will have the same pixel pitch, regardless of whether its LCD, Plasma, or anything else.

You may be referring to interpixel spacing, which refers to the portion of the panel not occupied by pixels (the area between them).

In any size panel, the smaller the pixel pitch, the better the image quality, which means really high resolutions. But I didn't want to say high resolution because a really big screen can have a really high resolution, but also a high pixel pitch.

Interpixel Spacing. Possibly yes, this might actually be the problem. I just assumed that having smaller pixels would have smaller spacings. The smallest Plasma pixel I've seen is about .6mm in comparison with LCDs which is about .255mm.
