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.

*Screen images simulated.

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.

Infinite Contrast

OLED puts LED in the shade.

Put simply, OLED has millions of self-lit pixels that can turn on and off to achieve perfect black and infinite contrast. That black is better than both mini-LED and LED TVs. So it doesn't matter how many thousands of backlights they have, LED TVs will still be in OLED's shadow.

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 bright scene, A girl is lying on the grass and the entire color gets clearer and more vivid as color volume rises from 70% to 100%. 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%.

*Display Color Gamut Volume (CGV) is equivalent or exceeds the CGV of the DCI-P3 color space as verified independently by Intertek.
**70% Color Volume refers to LG's UHD TVs.

Dolby Vision IQ & Dolby Atmos

A transformative TV experience.

Dolby Vision IQ intelligently adjusts picture settings based on content genre and ambient surroundings, while Dolby Atmos delivers multi-dimensional surround sound — a powerful combination that produces breathtakingly cinematic results.

Partnerships with Game Industry Leaders

An unbeatable combo.

LG continues to work with industry-leading companies to ensure you get the best possible gaming experience.

Combine all this with the stunning picture quality and ultra-fast response times of OLED and you're guaranteed to get the most out of gaming every time you play.

The Latest Gaming Specs

Play at the highest standard.

LG OLED TVs are capable of a 1ms response time, while support for VRR, ALLM, and eARC meets the latest HDMI 2.1 specifications. These features allow fast-moving content in higher resolution and smooth, synchronized graphics to give you a more lifelike experience and a better chance of winning. Additionally, OLED C1 and G1 are now the world's first TVs to support the incredible Dolby Vision® HDR at 4K 120Hz for gaming, enhancing the playing experience to previously unseen levels.
