The advantage is, it's cheaper, can provide better color accuracy, and won't burn in as bad as OLED since LEDs have much longer lifespan w.r.t. OLEDs.
I still can't accept to use OLEDs in TVs and computer screens. Both has much higher duty cycles w.r.t. phones and tablets, and I hate burn-in.
Having had OLEDs for a while now and never experiencing burn in even in my monitor I believe this issue is either very overblown by the small amount of bad experiences and requires a large amount of misuse before it becomes a problem.
RTings has done multi-year burn-in tests and OLED TVs have an exceptional lifespan before burn-in these days, I honestly don't know what motivates this particular concern any more. You'll probably have the caps fail before you notice anything, maybe even multiple rounds if you recap it.
