In our recent look at the state of OLED televisions, we focused on the present—but what about the future?
[...] LG isn't the only OLED player in the world, mind you, but it is currently the only OLED TV manufacturer in the United States, and it also makes the panels sold by Panasonic, the only other OLED TV player in the international market.
LG has said on the record that the white OLED technology purchased from Kodak gave it a giant lead over other companies' "RGB OLED" TV panels. LG says its panels cost far less to manufacture than the competition's—the panels' crystals are easier to line up in a cost-effective manner.
Others may well catch up in the larger-screen OLED space in the near future, of course. When that happens, it stands to reason that competitors, particularly the deluge of Chinese companies entering the TV manufacturing space, will combine aggressive discounts and other innovations to steal attention away from LG.
For now, many manufacturers do produce panels with OLED technology—though you may better know these as AMOLED displays. (You'll find them in smartphones from Samsung, Huawei, and Google.) Their main difference from larger-panel OLED displays comes from that "AM" prefix, which means "active matrix." This refers to the process of sending electrical current through the panel for the sake of pixel illumination, which used to be a less-efficient "passive matrix" process. The older way proved too power-hungry and slow for the kind of quick-performance screen refreshes needed in a smartphone. (LG doesn't advertise the kind of matrix employed in its latest OLED TVs, but based on what we know, it can probably be described as a combination of AMOLED and WOLED (white-emitting OLED).)
In the mobile-screen space, AMOLED and in-plane switching (IPS) LCDs continue to battle for supremacy, with each offering different color, brightness, darkness, thinness, power, and performance advantages.

Yes, burn in is a problem, but that what screen savers are for.
No, that's what using power management to turn off the damned display is for. Screen savers are a joke and a waste, just let them die already.

They were quite handy on CRTs though. Especially after a few years of use, a CRT might well take 5-20 minutes to "fully warm up" during which time color calibration and other properties would be different than in steady state.
But yeah, they were mostly an amusing distraction and a way to avoid having a large black rectangle filling your field of view while you were working on other things.
