此文是GMT时间08年2月22日11:19am在avsforum上发的(北京时间今天凌晨2:19发的)。原文也是转自其他网站,且原文很长,所以我就只主要翻译avsforum上转载的部分,其他部分我会大概翻译(其中有对等离子电视的使用方面的建议)。因为本人不是英语专业的(学工的),若是翻译的不好,请高手指点,呵呵。

The Myth of Plasma "Burn-In"
In the "early" days of plasma TV, image retention, or "burn in" was a real concern. Fortunately, modern sets are far less susceptible thanks to a few new safeguards.
Plasma TVs have been around now for several years now. They were the original flat-panel display designed for hanging on the wall or over the fireplace. From the beginning, they were the darling television of interior designers. In fact, the plasma has always had a certain cache, mystery, myth about it. In some ways, they represented the future with their “floating” appearance, which culled up visions of H.G. Wells’ prophetic novel “Things to Come.”
The perceived problem with plasma, however, is something called “burn-in” or more technically called “image retention.” This means that if you keep an image “frozen” on the screen too long, a ghost of the image will stay with the display forever. A good example of things that could leave permanent images on the screen could be news or stock tickers, or station logos or icons – sometimes called “bugs.” In the beginning, this was certainly an issue. Now, several years later, all of the leading manufacturers of plasma TVs – Panasonic, LG, Samsung, Pioneer, and Hitachi – have all taken several steps to greatly reduce or eliminate completely any signs of image retention.
According to Jim Palumbo, President of the Plasma Display Coalition (PDC), “New plasma advancements in cell structure and phosphor formulations have virtually eliminated image retention, also known as ghosting. Tests verify that any residual ghosting generally disappeared with normal use after a relatively short time. If you haven’t burned images into your CRT television, there is little chance that you will with plasma. As with any electronic product, you should follow the usage guidelines in your owner’s manual.” Basically the PDC 观点 is that image retention (burn-in) has been virtually eliminated and is no longer an issue.
在等离子出现的初期,余像或是烧屏确实是一种顾虑,让人担忧。但幸运的是,得益于一些新的保护措施现在的显示设备烧的可能性很小了
等离子已出现了若干年了,它作为起初被设计来挂在墙上或壁炉上(欧式建筑,围着壁炉看电视,爽啊)的平板电视,在一开始备受室内装潢者的追捧。事实上,关于pdp,一直就有一些神秘的,虚构的说法(不知如何翻译myth更为贴切)。在某些方面,等离子以其悬浮的外观展示着未来。这种视觉效果取材于 H.G. Wells的未来小说“things to come”
然而,人们在等离子上发现了一个问题,叫烧屏,或用专业术语“余像”。这意味着若长时间在屏幕上固定一个图像,就会永久性的在电视上留下影像。举几个常见的容易留下永久图像的例子,播新闻或证券价格的机子,或站名或标志,-有时被称作bugs.一开始,这确实是一个问题。而现在,也就是(等离子出现)几年之后(的今天),所有等离子制造业的领导者们-Panasonic, LG, Samsung, Pioneer,日立-都采取了一些步骤措施大大减少了,或完全去除了余像所留下的痕迹。
依照等离子显示设备联盟(PDC)主席的话,“等离子在气室结构和荧光粉配方的方面的新改进,实际上已消除了余像,或称作残影。试验证明任何残影通常都会在相对短时间的正常使用后消失。如果你没有在crt上烧上图像,那么在等离子上烧出来的可能性也很小。(最后)对于你身边的任何电子产品,你最好遵照你的说明书上的话去做。”基本上pdc的观点是余像(烧屏)现象实际上已经消除,而且也算不上什么问题了。
