  • 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.

    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.
