Electroluminescent Display aging - Was : Re: Flat panel display rot - "tunnel vision" in electroluminescent and other displays- bad seals.

Update: I've swapped the displays and drivers around, and the "tunnel" effect seems to be a property of the panel and not drive electronics. Perhaps they are all high-hour examples? Anyone here an electroluminescent display expert? > > > On Wednesday, July 20, 2016, Ian Finder wrote: > >> No, I'

Hmm. I suppose recapping is a logical next step. There are also four adjustable inductors and a single trimpot inside the display assembly. I haven't been able to find a single clue about what they do. On Wednesday, July 20, 2016, Ian Finder wrote: > No, I'm not convinced the EL repro isn't a d

No, I'm not convinced the EL repro isn't a driver electronics issue. I'm just a little confused about why the issue congregates at the edges of the displays. Any ideas why that might be? I may try swapping the panels around this evening if I am feeling brave. On Wednesday, July 20, 2016, Brent H

If anyone has a plasma that *DOES* repro, that would be very interesting, but I expect the technology is different enough that that won't happen due to the pressurization.

I'm happy for everyone with great displays, but I have never seen a repro on plasma because they are pressurized. And I've seen plenty of EL displays that still look great... So far. So can we stay on topic a little :) On Wed, Jul 20, 2016 at 1:15 PM, Cameron Kaiser wrote: > > > Better yet, doe

Yes, but as I mentioned: "> I think all two-glass-pane displays that don't have a vacuum may eventually > succumb to this." I have plenty of good displays. It seems like it may happen eventually. Also aren't plasmas pressurized, unlike LCD and EL? On Wed, Jul 20, 2016 at 12:56 PM, Paul Koning w

I have a few GRiD compass systems and some are suffering from massively decreased contrast on the edges of the displays: [See the system on the left] https://www.instagram.com/p/BIGGzUzgat-/?taken-by=tr1nitr0n [Or this one:] http://www.ripstick.com/USCM/images/Grid_Compass_1101_Laptop_in_Box_002.
