Electronics Companies Receive Darts and Laurels from Greenpeace

Philips and HP are bringing good things to the environment, according to Greenpeace’s latest Guide to Greener Electronics. The organization praises Philips for releasing the first television free of polyvinyl chloride (PVC) and brominated flame retardants (BFRs), both chemicals that persist in the environment after disposal and cause health problems. HP, Acer, Wipro, and HCL have also phased these substances out of several lines of computers, and HP has introduced its first PVC-free printer. Meanwhile, Nokia and Sony Ericsson remain at the top of the class, in first and second place respectively, for producing the most hazard-free products.

But Greenpeace isn’t happy with the entire electronics industry. The organization slapped Toshiba, LGE, Dell, and Lenovo for failing to stay on track in meeting their commitments to making their products greener. Toshiba got a second penalty point for misleading its customers, and Microsoft got slapped for actually backtracking on its commitments. The full Greenpeace Guide is here.

All these products use display panels manufactured by Samsung but have their own unique display assembly, operating system, and electronics.

I took apart a 55-inch Samsung S95B to learn just how these new displays are put together (destroying it in the process). I found an extremely thin OLED backplane that generates blue light with an equally thin QD color-converting structure that completes the optical stack. I used a UV light source, a microscope, and a spectrometer to learn a lot about how these displays work.
