Just due to their chemical nature, OLEDs are a whole lot less stable than their metal/metal oxide LED counterparts. Have they figured out a way around blue OLEDs from degrading faster than reds and yellows? IMO, since we keep TVs around a lot longer than our cellphones, OLED should just be restricted to "disposable" electronics
It seems that you just described an LCD using OLED as the backlight instead of LED or fluorescent. Pointless?i think LG's technique of using pure white OLED substrate with a colour filter in front is the most production efficient currently as only one chemical is required in the process.
I agree about the need for a curved display in the 55" range, however, I was talking to the audio / video manager of a local A/V shop, and he told me that the reason the screens are curved is not what us consumers would expect. It is a structural issue - the curved screen makes the display more rigid. He said that he was told this by one of the manufacturers at a recent show. Amazon has LG's 55" flat OLED TV, but it is more expensive than the 55" curved.I think one problem is that a 55 inch TV doesn't need to be curved, maybe an 80 inch, but not 55. They're just taking an unnecessary step there in manufacturing that's creating more expense.
I don't know how more recent models compare but I've had a 55" 7000 series samsung led/lcd tv and it's beautiful in lighted scenes but the moment the scene gets dark; backlight bleed on the edges. This is the main reason i would want to switch to an OLED, for the dark scenes, nothing else compares.
It is different because the White OLED sub pixels are actively controlled, unlike an LCD where you have a uniform or section dimmable backlight and an LCD matrix infront of it which limits the light through it and filters the colour and sections the backlight into sub pixels.It seems that you just described an LCD using OLED as the backlight instead of LED or fluorescent. Pointless?i think LG's technique of using pure white OLED substrate with a colour filter in front is the most production efficient currently as only one chemical is required in the process.
