[Category] Lifespan [Winner] Plasma [Explanation] 
OLED is unproven when it comes to lifespan, and there is some cause for concern here because the compound used to create the color blue in OLED televisions is known to have a shorter life span. As one color degrades, the rest will go out of whack. Samsung appears to be battling this issue by using a blue pixel that is twice the size of other colors and reducing the amount of voltage applied to it. LG uses white sub-pixels and lays a color filter over them to create the desired red, green and blue colors. These bandages may very well work, but only time and use in the public arena can tell how OLED will hold up on the long term. For that reason, we have to call LED/LCD the winner, as its lifespan has proven itself to be adequate
