What makes OLED unlike anything else?

The answer is self-lit pixels. A self-luminous display technology that makes all the difference to your viewing experience. Unlike LED TVs that are restricted by backlight technology, LG OLED TVs are capable of extreme realism and unique designs.

SELF-LIT PiXELS.
100 million reasons to love OLED.

When it comes to picture quality, OLED beats LED hands down. That's because OLED has millions of self-lit pixels capable of producing perfect black and accurate color. The result is a viewing experience like no other.

100% Color Fidelity

OLED passes with flying colors.

Global testing agency Intertek has confirmed that LG OLED displays have 100% color fidelity. This means that the colors you see on the screen closely match the colors of the original image. So everything you watch looks as the creator intended.

*Color fidelity determines whether a display's color accuracy is Delta E ≦2 across 125 color samples.
**83-inch LG OLED panel will be certified in the first half of 2021.
100% Color Volume

A dazzling display of color.

LG OLED TVs achieve full Color Volume thanks to the excellent color reproduction technology of LG TVs. With 100% Color Volume, LG OLED can express 100% of the DCI-P3 spectrum across a 3D color space that covers the TV's full luminance range. This means that colors remain vivid and lifelike with full saturation no matter how bright or dark the display.

In dark scene, a girl is holding a colorful umbrella and the entire color gets clearer and more vivid as color volume rises from 70% to 100%.
