OLED vs IPS LCD: Battery Life

[Sweepr]

Interesting comparison by HotHardware:

Lenovo recently sent us a new model ThinkPad X1 Yoga, equipped with a beautiful OLED display. This display carries the same 2560X1440 native resolution and 14-inch size as the first model we tested that was equipped with an IPS panel. However, the specs for this OLED-powered machine are somewhat different as well, with a slightly faster Core i7-6600U processor (versus i7-6500U in the IPS enabled X1 Yoga) and 16GB of RAM versus 8GB (IPS model). Regardless, the configurations are similar enough that it gives us an opportunity to compare battery life results between the 14-inch OLED and IPS panel options in Lenovo's ThinkPad X1 Yoga line. We think you'll be pleased with the results...

Now let's appreciate this display:

Looks like power consumption is really dependent on the type of movie/video etc (which is not really surprising, given OLED).

Except for some burn-in ghosting (After keeping an image for 10 minutes), it looks really promising. Easily beating LCDs. Hopefully we'll see some more OLED monitors/laptops with cheaper prices soon.

How serious is the burn in problem? I'm guessing some progress has been made in the last few years?
