      OLED pixels are self emissive, which means each pixel emits its own light. Normal LED screens need a backlight (usually coming in from the edges) so you get light bleeding into what should be black pixels. OLEDs just turn off the pixel entirely. Some new LED screens are starting to be fully backlit which eliminates the light bleed problem but they are not widespread yet.
