Struggles with deep blacks and bright highlights.
One row of LEDs has to try and balance light through the whole picture. Dark parts are not as dark, bright parts are not as bright - more blooming is likely.
Brighter highlights deeper blacks.
Intensity of the LEDs will be adjusted depending on the scene – light where light is needed, dark where darkness is needed.
The real benefits of Full Array LED with local dimming is that you get more realistic peaks of brightness, more accurate shadow detail and deeper, inkier blacks. A good example of this would be seeing the moon in the night sky. On an Edge-lit or Direct-lit TV, you would sacrifice the brightness of the moon for a blacker night sky (or vice-versa) and the blacks would still likely stray into blue or grey. On a Full Array LED TV with local dimming (like the X95H) you get a beautiful, natural picture, with a clear, bright moon and a dark, authentic night sky.
By precisely balancing the light output across the screen, dimming some areas and boosting others, X-tended Dynamic Range™ PRO reveals a brightness range several times greater than our conventional LED-backlit TVs, ensuring dark scenes are darker and bright scenes are brighter.
