Perfect excuse for getting that colour LCD or LED :) Michi. Link to comment Share on other sites More sharing options...

I do not leave my machine on when I'm not playing it, so hopefully I can get good mileage from the LCD before burn-in begins to show.

Cheers, Matthew Have a look at any ATM or POS screen that has been installed for more than 5 years and there is a chance you will see it. I wouldn't worry too much, it has taken 20 years for DMDs to screen burn, I would expect about the same from LCD so it really isn't an issue.

0 Michi Posted July 3, 2017 Share Posted July 3, 2017 what about LED? They do get dimmer as they age. But the 70% luminosity point takes something like 20,000 to 40,000 hours to reach. If you have a machine switched on eight hours a day, seven days a week, it'll take around ten years to get to that point, so I wouldn't worry about it all that much :) Michi.

True that they do lose light output intensity with age BUT they won't exhibit the same "screen burn" effects that CRT and LCD do. Link to comment Share on other sites More sharing options...
0 maxi Posted July 3, 2017 Share Posted July 3, 2017 Best way to see this is too look at an old pokie CRT. The reels are almost always burnt into the screen. Link to comment Share on other sites More sharing options...

It's still deterioration, but of a different kind. At any rate, at the life span of LEDs, I don't expect it will ever be an issue, except maybe for games on location that are on 16 hours a day. Even then, it'll be years before they will noticeably dim. Michi. Link to comment Share on other sites More sharing options...

0 razorsedge Posted July 18, 2017 Share Posted July 18, 2017 The "outgassing" can also create excessive load for your dmd high voltage supply and other components. It's a good idea to replace it asap. I can vouch for the LED ColorDMD, you don't get the high res modes etc. but boy are the colous brilliant and bright... and I would figure they may have better longevity than LCD. Also they are a bit closer to original dmd size and also are slightly less costly. :) Link to comment Share on other sites More sharing options...

I see these panels all the time with a single pixel out, VERY common and unrepairable in the majority of cases. Link to comment Share on other sites More sharing options...
0 razorsedge Posted July 19, 2017 Share Posted July 19, 2017 Yes of course. I have heard of numerous premature LCD panel failures also though. I have two of each (LCD and LED) and have experienced no problems with any of them so far, I do prefer the appearance of the LED version I suppose I meant. :) Link to comment Share on other sites More sharing options...

I love it, I wouldn't go back to dots on a TAF no matter how vibrant the colours are on the LED. The larger size panel on the LCD does not worry me at all, and I'll worry about failure if/when it happens, not now when it is working perfectly!

0 razorsedge Posted July 20, 2017 Share Posted July 20, 2017 I do have to admit I really love the hi-res on my Whitewater! :cool: . Still, the serious lack of brightness makes them look very washed out alongside the plasmas and LEDs in the arcade environment I have here. I know LED segments can go out, I guess I will just have to keep fingers crossed that reliability is still on the improve. Either preference, ColorDMD is Great in my experience! :023: Link to comment Share on other sites More sharing options...
