参考翻译:10年2月4日松下对该问题的官方回应:
“使用期内的自动对比度调整”
松下Viera等离子电视机在其使用期间提供出众的画质表现。所有显示设备的元件和材料特性会在使用过程中发生改变。为了让产品在整个使用期内达到最佳的画面效果,松下Viera等离子电视使用了一种自动控制,它按照预先设定的使用间隔期调整内部驱动电压。
这种自动电压调整的结果是,背景亮度会比初始值增加。经过几年的正常(原文Typical)使用,内部材料特性将会稳定,也不再需要额外的电压调整。在这个稳定点上的黑位就会产生极佳的图像效果。
最新的Viera等离子电视使用了改进的自动控制,电压调整幅度更小。这导致黑位随着时间的变化更缓慢了。

Panasonic's Official Response to the Issue as of 2/4/10
"Automatic Control of Contrast over Operational Lifetime."
Panasonic Viera plasma HDTVs deliver exceptional picture performance throughout the lifetime of these products. Various elements and material characteristics of all electronic displays change with use over time. In order to achieve the optimal picture performance throughout the life of the set, Panasonic Viera plasma HDTVs incorporate an automatic control which adjusts an internal driving voltage at predetermined intervals of operational hours.
As a result of this automatic voltage adjustment, background brightness will increase from its initial value. After several years of typical use, the internal material characteristics will stabilize and no additional automatic voltage adjustments are required. The Black Level at this stabilized point will yield excellent picture performance.
The newest Viera plasma HDTVs incorporate an improved automatic control which applies the voltage adjustments in smaller increments. This results in a more gradual change in the Black Level over time."
