Excellence on Screen


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.


Slimline Design

Blends In. Stands Out.

Inspire your interiors with the ultra-slim OLED that adds minimalist charm to your space.



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.

TV and Soundbar in Harmony
