I have a suggestion to extend life of oled TVs.
I have read many manufacturers are doing attempts to prevent permanent burn in or Image retention. the most stupid one with another manufacturer was to show a screen saver even if you are watching movie if you do not touch the remote buttons for 30 minutes.
One best approach is to show screen saver when there is no one watching TV, for example when the TV is in the Living Room, a very cheap motion detection sensor at wide angel can detect movements and if there is no one there you can show screen saver or whatever good for oled, the type of sensor is your business.
There are many times a person in the house turns our the TV and is doing his/her things and moving between rooms, the TV can rest bug just the audio is on.
This is also good if someone is working in the kitchen and just want to listen to the TV.
User should be able to customize or turn off this feature.
