OLED puts LED in the shade.
To put it simply: OLED TVs have millions of self-illuminating pixels that can be switched on and off and can thus achieve perfect black and infinite contrast. This black is deeper than that of mini LED and LED TVs. So it doesn't matter how many LED light sources are built into the backlight or how many dimming zones they are organized in - LED televisions are always in the shadow of OLED televisions.
