[Category] Viewing Angle [Winner] Plasma (for now) [Explanation] 
Plasma wins this category for now, but only because the few OLED TVs on the market right now are curved, which complicates things. If we were comparing plasma and OLED on flat displays, it’d likely be a tie between the two – both technologies offer excellent viewing angles because they don’t rely on LCD panels to block out light, but the currently available curved OLEDs introduce the following problems: First of all, the side that is curved away from an off-axis viewer will be less visible than the side curved toward that viewer, and second because of the curve, anti-glare coatings can tend to tint the image when viewed from extreme angles.
