We know the limitations of lcd displays vs oled is that lcd screens are not emissive, they need a backlight to light up the pixels of the lcd screen. Some tvs have local dimming where they have zones of of the led backlight that can turn on and off. Well... what about going all the way to each individual pixel? Is it possible/feasible to have a per pixel led backlight that could turn on a backlight for each individual pixel to varying degrees as needed to achieve similar results to something like an oled and perhaps beyond with increased peak brightness?
Or is that not doable with current technology or has some other engineering challenges or just too expensive?
