Panasonic will release plasma panels with its NeoPDP tech in Spring 2008. NeoPDP is a 5 lumen/watt technology that improves the luminance efficiency of plasma panels. This doubling of efficiency can be used to double panel brightness, halve power consumption, and/or improve image performance by using blanking and timing tricks that would of been too resource expensive with the prior technology. The final embodiment of 5 lumen/watt tech will probably be a balanced combination of all of those attributes. This technology may also lead to thinner and lighter panels.
Pioneer and Panasonic are sharing numerous plasma patents. Next years Pioneer Kuro 10G plasma displays will be using Panasonic glass and are expected to use this new 5 lumen/watt technology. So will the next generation Panasonics be as black as the next generation Pioneer Kuros? Or does Pioneer still have some tricks up its sleeves?
I've heard that the zero idle luminance of the Extreme Contrast Concept requires the 5 lumen/watt technology. It is unknown whether this new technology is the sole source of the zero idle luminance or if darker filters coupled with increased brightness are to be credited with this significant "extreme" improvement. Zero idle luminance will likely be a combination of these two techniques which will question the accuracy of "absolute zero" and "infinite contrast" claims. Does black enough really require a divide by zero error?
For comparison reference the current Pioneer Kuro 9Gs utilize a 3 - 4 lumen/watt technology and achieve a 0.001 fL idle luminance. This is low level of idle light is beyond the current measurement limit of many calibration tools. In a completely dark room human eyes have no problem discerning it though.
