The OLED the World Wants to Watch

α7 AI Processor 4K Gen6

Evolution at Its Core

Enter the world of α-realism1. A portal to new universes and the sensation of feeling like you're really there. Be the main character surrounded by the exceptional picture and sound refinements of α7 AI Processor 4K Gen6.

AI Super Upscaling

The AI processing system uses AI Noise Reduction and AI Super Resolution to classify images and remove noise based on their category. Then, deep learning algorithms enhance faces and objects to make them look more defined, expressive, and multi-dimensional without appearing artificial.

OLED Dynamic Tone Mapping

OLED Dynamic Tone Mapping refines what's in the frame by applying the optimal tone curve for more natural HDR, contrast, and detail.

AI Sound Pro

Step Into a Realm of Cinematic Sound

The movie theater comes home with AI Sound Pro. Heart-pounding, room-filling, crystal-clear audio surrounds you for a level of immersion that's virtually unheard of.

Virtual 5.1.2 ch

Sound that surrounds you

Virtual 5.1.2 Surround Sound puts you at the heart of the story. Hear fighter jets zooming overhead, footsteps rustling behind you, and the swell of the orchestra as it reaches the crescendo.

Dynamic Sound Booster

A heart-pounding audio experience

Heighten home cinema with audio that packs a punch. Dynamic Sound Boost amps up the power, immersion, and impact of everything you hear.

A video of a person playing violin with a yellow bubble and wave depicting sound. The scene changes to a singer and band playing an intimate gig in a lounge. Blue sound waves surround the singer, turquoise soundwaves emit from the guitar, and purple soundwaves come from the cello.

Adaptive Sound Control

Sound tailored to what you watch

Whether it's a blockbuster movie, acoustic set, or family video call, sound is balanced in real time for optimal audio in any scenario.

A video opens showing an aerial shot of the remote control. A blue circle appears over the sensor. The scene pans out to show the remote control on a coffee table in a gray room. Blue soundwaves emit from the TV, and an image fills the screen showing a person kayaking over choppy waves. The blue sound waves reach the remote control, and waves depicting sound bounce from the wall, and then a blanket of sound covers the room.

AI Acoustic Tuning

Perfectly tuned from wall to wall

Your remote control detects the sound in real time and customizes it to fit the unique acoustics of your space and surround you in sound wherever you're sitting.

*Screen images simulated.

**Sound may vary according to the listening environment. 

***AI Acoustic Tuning must be activated in the AI Service menu.

****Remote control may vary by region.

SELF-LIT OLED

No Backlight Necessary

Pixels reach their brightest, most brilliant potential when they stand alone and shine without the dull glow of a backlight.

What Makes OLED Different?

While traditional LCD TVs feature bulky layers of backlights and color filters, OLED is made up purely of self-lit pixels for unrivaled contrast and sleek design.

Infinite Contrast

With deep dark blacks that can only be achieved by self-lit pixels, bold contrast reveals details your eyes usually miss with crisp, defined visuals.

100% Color Fidelity & 100% Color Volume

With 100% color fidelity and volume, colors are displayed exactly like the original, with rich tones in both bright and dark environments.
