Screen Burn-In? [Archive] - Android Forums

I'm wondering if screen burn-in is possible/likely on the G1 if the screen is left on for a long period of time (i.e., 5-10 hours) with no activity. What do you guys think? Specifically, I'm talking about the "locked" screen that you get after hitting menu once (before hitting it a second time), where the brightness automatically dims after a few seconds (it will stay on indefinitely if you enable the development mode option).

I'm asking b/c I'm having a problem where my G1 intermittently locks up in sleep mode when I'm at my home (it is related to the cell tower(s) my G1 connects to when at home), so I've been thinking about leaving it on so that I don't miss any calls b/c my phone is unknowingly frozen. Can I do this w/o worrying about screen burn-in?

it is going to be more common in plasma screens and the good ole CRT tv's... LCD's can still be victim to burn in, but this typically takes a very extensive amount of time to actual start to show the "ghost" images that you may have seen...

i wouldnt' worry about it with most modern screens... i believe synaptics uses pixel-shift technology where an unoticeable shift in the screen is done at certain intervals, but i'm 50/50 with it on the screen on the g1... i'll try to take a deeper look into it, but it will more than likely take an e-mail to a technician at synaptics to get the correct answer, as its not readily advertised on most LCD screens/tvs

most modern LCD screens are also rated 20,000 hours+... as long asyou take care of the screen, the device is more likely to break down before the LCD screen does... theres really nothing you can do to protect against it other than making sure its off, or utilizing a screen saver that moves around the screen to "refresh" pixels, but that is obviously not a good battery saver... if you're going to be leaving your phone screen on because of your cell tower issue, i would recommend a low power consumption screen saver that moves around the screen as to not burn in any pixels, if such a thing exists on the g1 yet...

Wow, thanks for all of the info! I really appreciate it. Unfortunately, I don't believe there's any type of screensaver out for the G1 (at least I couldn't find anything), which sucks b/c I only want to leave the screen on when at home, which means I'll have it charging so battery life is not an issue. It sounds like I'm more than likely ok to leave the screen on for a few hours w/o a problem, so I think I may try that out. Thanks again!

np, i like to be thorough with my posts including backup information, tends to be the reason why people ignore them...

anyway, i still recommend using a screensaver app if ever released... better to be safe than sorry... cause well, it really does save the screen

Thanks again. I'm going to keep my eyes open for a screensaver app as this would obviously be the best choice. Hopefully someone decides to make one soon.

You could use the strobe light app on cycle colors. I don't know if that would work but its my best idea... does anyone know if that would work?

Thanks a lot - I think strobelight actually is a really good idea. Since it cycles the entire screen through all different colors, I'd imagine that would do the trick. Thanks!

Tread is correct, LCD screens don't suffer from burn-in as CRT & Plasmas do, rather they can suffer from what the manufacturers call image persistence. In most cases it isn't permanent and can be reversed by 'exercising' the pixels.

The effect is likely to take a very long time, like weeks/months of continuously displaying the same image.
