On the subject of displays. Life time is not only measured to half brightness it is also measured to where non-uniformities become obvious. So a color display's life can be over when one color fades quicker then another or where the screen image starts to become blotchy. Humans tend to be very sensitive to displays our eyes can pick up linear shifts of as little as 4 microns. I refer to this as being the image processing filter in our brain that eveolved to spot the tiger in the jungle.
I should mention my last non-elf employed job was developing test equipment for an fed company. They made really beautifull displays that had a life of a hundred hours or so.
