While LCDs are not susceptible to burn-in the same way CRT monitors are, LCDs suffer from what manufacturers call image persistence. Like the burn-in on CRTs, image persistence on LCD monitors is caused by the continuous display of static graphics on the screen for extended periods.
Do LCD screens suffer from burn-in?
Although much less susceptible than Plasma TVs, LCD TVs are still subject to screen burn in (image retention). In general, you should avoid keeping a static picture (that is, a picture that contains no or few moving elements) or a picture with static elements (black bars, black borders, logos, etc.)
How long do LCD screens last?
LCDs have a lifespan of about 50,000 hours, or 5 years — half the lifespan of LED.
How long does it take for an LCD screen to burn?
5-15 minutes in susceptible panels with varying severity. That said, most LCDs do not suffer from image retention at all.
Does LCD burn-in go away?
Burn-in on the LCD screen is a form of image retention but is permanent and virtually impossible to fix. The prolonged use of static images would cause screen burn-in.
