A:Answer Generally, OLEDs have much better contrast then LED. OLEDs have an infinite contrast ratio because each pixel emits its own light, while LEDs rely on a backlight. This allows OLEDs to produce true black colors, while LEDs can't completely block out light. OLEDs have an infinite contrast ratio, while LED displays vary in quality. OLEDs produce pure black colors by turning off pixels entirely. LED displays use a backlight, so they can't achieve true black. LED displays can often achieve higher brightness levels than OLEDs. OLEDs typically have better color accuracy than LED displays.
