LG SELF-LIT OLED technology

LG self-lit OLED is the pinnacle of TV technology. All of the screen's pixels are self-lit allowing for perfect contrast, 100% colour accuracy and volume, and the sharpest pixel-perfect details, creating an astonishing viewing experience. LG OLED enables uncompromised picture quality at any viewing angle so everyone in the room can enjoy the same stunning images regardless of where they sit. OLED technology also provides a safer and more comfortable viewing experience thanks to its flicker-free technology and certified low blue light levels. This means less fatigue to your eyes during those boxset marathons, nail-biting championship games and intense gaming sessions.


Intelligent processor for optimised pictures and sound

LG OLED B4 features the new α8 AI Processor, the brain of the TV. This intelligent processor intuitively ensures optimised picture and sound quality and delivers image enhancement through AI Super Upscaling. It will also upscale audio for a more cinematic experience.


Smart Platform

Exceptional sport experience
LG OLED delivers you the realism and intensity of the sports stadium experience at home, with uncompromised picture quality at any viewing angle regardless of where you are sitting. Exceptional picture quality with immersive sound (AI sound Pro) is enhanced by the smoothest motion (OLED Motion) so no matter how intense the action is, OLED keeps every detail of the game in diamond sharp focus.
