I'm new to Plasma technology, but am excited about the new Pioneers (I like the Pro-FHD1, except for its poor black level -- the 8G should be great).
However, looking closely at the screen, and moving my eyes around, I see waves of sparkles -- usually yellow, though the other colors are there too. I also see static patterns of colors in the darks -- almost like the days of 8-bit computer displays, where images had to be dithered.
I noticed this on all plasmas, though it seemed less noticeable on Fujitsus. It was clearly there on the Pro-FHD1 Pioneer, and was there on Panasonic panels.
I couldn't notice any problems from normal viewing distance (8-10 feet), but at less than about 4 or 5 feet, I could still see these sparklies.
Is this something inherent to the operation of plasmas that can never be improved? I realize source noise may have something to do with it but not much -- it doesn't show on LCD at all, with the same sources.
Is the problem that plasma pixels need to be driven to some minimum brightness level for them to work? If this is true, then to get darks, they need to do brightness dithering (turning on and off quickly, and in patterns)? However, I also notice the sparkling when I move my eyes around a smooth bright scene. Its as if there is a fast on-off pattern that is being retained on the retina as the eyes move - even from a solid whitish scene.
If so, it is a bit of minus for plasmas at close viewing distances, or in large panel sizes. I know I could not live with the sparklies at 5 feet. Only 8 feet totally cured the view on a 50" panel.
The Fujitsu panel I saw had it, but not as obviously. Do they just have better processing for driving the panel?
