LCD screen burn in

Postby sylus » Wed Aug 24, 2016 1:29 pm

Yesterday i saw my LCD have a persistant ghosting screen even after shut off my printer for a while.
Is it normal? and is it possible to implement an a screen saver or pixel shifting?

I see the same at my printer. I deactivated the second extruder via the GUI - now I still see elements of the dual extruder GUI while the printer is switched on.

Noticed the same thing this morning. I did expect it would happen due to the brightness since always being on & running, just didn't expect it in 60 days. I guess I should get a spare or two.

It definitely needs a screen saver considering the lengthy print times we are all doing.

Well considering the R3d price point, it's a trade off I'm sure. It's not an issue for me until I turn it off & I examine the display. I guess it will be a year or two before it becomes a real display degradation issue, and it may never be a show stopper. Maybe by then R3D could have an upgraded controller display available, if time & finances warrants. I will eventually pickup another touch controller, just to have spares of most everything, just in case Murphy's law happens.

Man that sucks. Mine runs nearly nonstop anymore. This should have a screensaver mode. I hope they do a firmware update to make this happen.

So I guess until that happens maybe the best thing to do is not leave it on the home screen when its printing. Randomly select the print page, tune and other pages so the screens are in a bit of rotation while its on.

I'm not surprised this happen. My Samsung Galaxy tablet 3 also suffered burn in from playing Sim City for only a few weeks.

What I'm doing now is when I start a print and need to go to work or sleep. I go to the menu screen and hit Options then hit Camera. That clears off the 4 main button from the bottom of the screen and it mainly just shows black. Hopefully this will help prevent or hold off burn in for a while.

Yes. Raise3D. Please make a "Screen off" or a "Screen saver" on your next firmware update.

I‘m so sorry the next upgrade is almost finished. So it is hard to add this function in next firmware update. Maybe in later version.

I thought that only happened on CRTs!? First I've ever heard of an LCD and burn in, but given the machine runs for days on end I guess it makes sense. Is there a brightness setting?

Yes, you can adjust the brightness of the screen in Setting -> Other on screen.

On my N2 the brightness setting is not retained between power cycles. Every time the machine is turned on it resets brightness to level 6. Is this normal?

Thanks

Well noted. We will test whether we can add this function.

The N2 models does have. Reset switch right? Could you replace the switch with a toggle switch? To turn the screen off completely.

Screen saver has already been added in version 0.9.0 touchscreen firmware.

For the hardware, we are currently developing a new screen and display method. After complete designing and fully tests, it will be released in the next few months.

This topic have near one year and the statement from Raise3D:
Ghosting yes it is but we are not take in warranty this issue.
Sorry for that but you should regarding EU regulation (living in Eu) it's an defective LCD unit and you must cover for 2 years the printer (LCD are not consumable items).
Even it cover by hidden failure also cover by French regulation.

Finally Ghosting on LCD (LED or usual back lighting) is not a common failure as plasma or OLED does
you will be welcome to gently accept my demand of changing spare parts for an non defective one according to EU laws.
