Energy savings of OLED TVs worthwhile investment?

This is my understanding of OLED technology. Smart phones started using OLED screens years ago because:
Better picture - blacker blacks etc
More energy efficient
Less expensive

OLED technology has steadily worked itself into big screens but the price remains pretty high at this time. I don't know how much energy savings, if any, they represent at this time.

I'm considering an ~ 40" TV to replace the current screen but OLED technology is far too expensive at that picture size.

Perhaps someone here has more up to date findings on OLED television sets? 

Off gridders should usually be pretty interested in energy savings. Especially considering that TVs are often viewed after the sun has set. Between the modem streaming data and the TV the night time energy usage is significant.

    Energy savings appear quite strong. Price remains quite high. Probably much more efficient to make smart phone OLED screens than big screen OLEDs. The manufacturing process is very, very different. I suspect OLEDs are the future of the better and larger TVs.

    UPDATE: Seems OLED TVs use more energy than LED TVs. Watching dedicated video right now.

    I've never seen any company state that OLED consumes less energy than LED. When I observed the consumption with a kill a watt meter on a job site, the OLED consumed 30% more power than the LED that was replaced. 38watts vs 51 watts. The OLED screen was slightly smaller also. Another item to watch for is how bright the light is entering the room the OLED is placed in. Curtains need to be adjusted to reduce admittance of light.

    Originally smart phone oled screens were both cheaper and more energy efficient. Now it appears that some are back to using led screens so they must now be cheaper. Though led screens may get brighter than oled screens the oled screens have much better contrast via truly black blacks and a few other features. 

    Yes, oled screens use more energy than led screens on television sets. Technology marches along and things change. Oled screens generally rate a G on Energy Usage while comparable led screens rate a slightly better F. Both would have earned an A under previous energy usage guidelines according to one study. 

    Very roughly speaking one can figure that a 55" tv uses an average of roughly 55 watts during use. 1 1/2 watts when unpluggged. Don't unplug some oled sets because they run mtce procedures while unplugged. The technology is a bit impressive. 

    I recently could not give away a 65" Samsung with stand that cost over $3000 in 2007. That felt a bit "oddish". 

    No telling how good tv's will get in the future. Though the EU recently scrapped the idea of 8K tv sets.
