You seem confused. I'm not questioning the resiliency of LCD, I'm commenting on your quote listed below:
Which I already stated, those displays are running on a continual loop for extended hours during the day. I'm not referring or questioning LCD all together.
And not to mention, that one poster that experienced burn in you indicated in your Post m, that's one device out of the millions of Galaxy devices that are sold that likely never will experience image retention. That's not much of a metric to go off on a tech forum, when it's not necessarily indicative of real world experience without knowing how many devices actually are subjected to image retention.
