      HDR uses multiple images to process an image with more contrasting colours. Because lenses can only bet set for low light, medium light or high light. You can’t mix them up.

      Similarly on displays they can only dim brightness per area of the panel and the light leaks to other areas.

      Micro led can turn each pixel off individually so you get the true value of brightness displayed.

        That’s composite or stacked HDR, a photography technique - ‘High’ is a pretty arbitrary term but plenty of camera sensors are capable of capturing a super wide dynamic range now.

        HDR in displays is a different thing though.

      Essentially in OLED every pixel can turn off. So instead of displaying black. It’s actually just off, so pure black. This leads to really clear pictures. No light around a cursor. Also allows you to have a always on display because you’re only using 200 pixels instead of 1million
