In the case of a CRT, true "screensavers" light up the screen in pseudo-random patterns, which smooth out transitions to areas that have high burn-in.
For VFDs, what you're saying might be true near the end of pixel life, but it doesn't seem to work that way during the bulk of the lifespan. On my AV receiver, for example, which uses a VFD similar to what's in the Squeezebox, it's quite easy to see the intensity even out after all the pixels are lit for a few hours. There's no way that brighter pixels have worn themselves down in that time to the level of other pixels that might have been used hundreds or thousands of hours more. Perhaps it's not the phosphorous elements, but the driver circuitry, that's affected. -- TiredLegs ------------------------------------------------------------------------ TiredLegs's Profile: http://forums.slimdevices.com/member.php?userid=6201 View this thread: http://forums.slimdevices.com/showthread.php?t=63882 _______________________________________________ discuss mailing list discuss@lists.slimdevices.com http://lists.slimdevices.com/mailman/listinfo/discuss
