The large screens are also very heavy, so flat-panel displays using plasma-addressed liquid crystal (PALC) displays were developed in the 1980s. These electron guns emit electron beams that are manipulated to become display images on a phosphorescent screen. There are plugins available to install that make use of the De-Esser software.

It would be almost 20 years after the first standby release was drafted before anyone outside the company understood the dangers of the chemical and how far it had spread beyond the plant. An assistant medical director named Vann Brewster suggested that an early draft of the study be edited to state that DuPont should conduct further liver test monitoring.
But the company forbade him from publishing some of his research and, according to epidemiologist and public health scholar David Michaels, fired him in 1937 before going on to use the chemicals in question for decades. "[Teflon cookware] is totally safe for consumer use and commercial use. DuPont's Clayton also observed that humans differ from animals in their response to Teflon fumes. "The data overwhelmingly indicate there are no adverse health effects". Smokers can be exposed to higher levels of Teflon fumes, and they also may be more susceptible to harm from Teflon fumes, since many smokers have diminished lung function stemming from their chronic exposures to tobacco smoke. In the 1974 study, 14 percent of the workers reported succumbing to the illness more than three times in the year preceding the survey. Officials for DuPont, which makes Teflon, claim the non-stick cookware is safe, if used correctly: "We try to make sure consumers understand proper use. At the hospital, doctors noted that her heart was racing, and she had high blood pressure, increased white blood cell count (leukocytosis) and was breathing heavily.

In 1977, the National Institute for Occupational Safety and Health (NIOSH) set workplace standards to protect smokers from polymer fume fever, banning smoking for all workers who come in contact with Teflon in the workplace. One of tens of thousands of unregulated industrial chemicals, perfluorooctanoic acid, or PFOA — also called C8 because of the eight-carbon chain that makes up its chemical backbone — had gone unnoticed for most of its eight or so decades on earth, even as it helped cement the success of one of the world's largest corporations.

DuPont then designed a second experiment to learn how many cigarettes a single worker would need to smoke, each laced with a lower dose of Teflon, to elicit the same illness. Humans develop polymer fume fever at an exposure of 0. "Toxic Substances Health Risks Warrant Ban of Chemical". Over the past 15 years, as lawyers have been waging an epic legal battle — culminating as the first of approximately 3, 500 personal injury claims comes to trial in September — a long trail of documents has emerged that casts new light on C8, DuPont, and the fitful attempts of the Environmental Protection Agency to deal with a threat to public health. A DuPont scientist reported that workers themselves first deduced how to avoid the illness prior to controls instituted by the government in 1977: "Workers carrying the hot sintered [Teflon] shapes from the ovens to cooling benches found that if they carried them close to their chest, they developed a condition which came to be known as the "shakes"...

The next year, an in-house DuPont attorney named Bernard Reilly helped open an internal workshop on C8 by giving "a short summary of the right things to document and not to document. " Three of five workers at a Mississippi plant that manufactured plastic signs and rubber and metal stamps developed several episodes of polymer fume fever over nine months which, after an extensive NIOSH investigation of many chemicals used in plant processes, were ultimately linked to the workers' periodic exposures to PTFE in a mold-release spray heated to 305 °F (152 °C).
Although DuPont has not studied the potential long-term health impacts of chronic exposures to Teflon fumes from home cookware, the studies the company has conducted, including their human experiments, contradict their frequent assertions that heated Teflon is known to be safe. Neither has the prevalence of polymer fume fever from the use of home cookware been studied, although cases are reported in the peer-reviewed literature. But Reilly — whose own emails about C8 would later fuel the legal battle that eventually included thousands of people, including Ken Wamsley and Sue Bailey — didn't heed his own advice. Several months later, they measured an unexpectedly high number of kidney cancers among male workers. As the federal government intensifies its review of a toxic Teflon-related chemical that widely contaminates human blood, researchers are raising questions about the scientific basis for DuPont's assertion that the brand-name product is itself safe in normal use, a claim the company has offered to the public and the media repeatedly over the past year. The executives, while conscious of probable future liability, did not act with great urgency about the potential legal predicament they faced. "I said, 'I was in Teflon. "And he said, 'No, no. '" Other times, he's somehow inexplicably back at work in the lab.

The top-secret document, which was distributed to high-level DuPont employees around the world, discussed the need to "evaluate replacement of C-8 with other more environmentally safe materials" and presented evidence of toxicity, including a paper published in the Journal of Occupational Medicine that found elevated levels of prostate cancer death rates for employees who worked in jobs where they were exposed to C8. "Fumes from heated Teflon kill birds, sicken humans: Environmentalists want warning label. Also, as he noted in another prescient email sent 15 years ago: "This will be an interesting saga before it's thru. A worker grinding a Teflon-coated surface developed polymer fume fever.
