OLED TV technology uses Organic Light Emitting Diodes that display a bright picture with deep black levels vivid colors with higher contrast and faster refresh rates than other TV technologies. OLED TVs are also thinner allowing a very attractive and less bulky looking design. The OLED panel technology allows each pixel to control its brightness independently from other pixels. Since each OLED pixel is an independent light source it self-illuminates the image with precise details. Chameleon Extreme is SKYWORTH's advanced picture improvement technology. It intelligently optimizes contrast details and color tones to deliver the perfect picture. HDR10 is the original standard of HDR for Hollywood video production that is compatible with 4K Blu-ray discs 4K players and 4K streaming content. HLG is the broadcast standard for live HDR production. The Dolby Vision HDR format developed with Dolby Labs adjusts the picture on a scene-by-scene (and even frame-by-frame) basis to let you see a more dynamic picture with better detail and color accuracy. Dolby Atmos developed by Dolby Labs expands on existing surround sound systems by adding height channels allowing sounds to be interpreted as three-dimensional objects.
