EDGE podsvietenie:<\/strong>
Pri tejto konfigur\u00e1cii s\u00fa LED di\u00f3dy umiestnen\u00e9 pozd\u013a\u017e spodn\u00e9ho okraja displeja.

      \n
    • EDGE podsvietenie:<\/strong> Lok\u00e1lne stmievanie je takmer nefunk\u010dn\u00e9, preto\u017ee funguje iba vertik\u00e1lne odspodu nahor \u2013 scen\u00e1r, ktor\u00fd len zriedka zodpoved\u00e1 typick\u00e9mu video obsahu.<\/li>\n\n\n\n

      Supreme UHD Dimming je obchodn\u00e1 zna\u010dka registrovan\u00e1 spolo\u010dnos\u0165ou Samsung v janu\u00e1ri 2016. Ide o jeden z n\u00e1zvov technol\u00f3gie lok\u00e1lneho stmievania<\/em> pre UHD telev\u00edzory.<\/p>\n\n\n\n

      T\u00e1to technol\u00f3gia bola prv\u00fdkr\u00e1t implementovan\u00e1 v modeloch s\u00e9rie 9 s SUHD displejmi zalo\u017een\u00fdmi na kvantov\u00fdch bodoch. V roku 2018 bola pou\u017eit\u00e1 aj v modeloch s\u00e9rie 7. Do roku 2024 sa Supreme UHD Dimming pou\u017e\u00edva v telev\u00edzoroch s EDGE podsvieten\u00edm a Mini Direct LED podsvieten\u00edm.
