Rozdiel medzi UHD+ a \u0161tandardn\u00fdm UHD<\/strong><\/h2>\n\n\n\n

Hlavn\u00fdm rozdielom medzi UHD+ displejom (5120 \u00d7 2160) a \u0161tandardn\u00fdm UHD displejom (3840 \u00d7 2160) je zv\u00fd\u0161en\u00fd po\u010det horizont\u00e1lnych pixelov. Obe rozl\u00ed\u0161enia maj\u00fa takmer rovnak\u00fd po\u010det vertik\u00e1lnych pixelov, ale UHD+ pon\u00faka viac horizont\u00e1lnych pixelov, \u010do je ide\u00e1lne pre \u0161irokouhl\u00e9 monitory. Av\u0161ak displeje s touto rozl\u00ed\u0161en\u00edm neboli p\u00f4vodne navrhnut\u00e9 \u0161peci\u00e1lne pre \u0161irokouhl\u00e9 pou\u017eitie.<\/p>\n\n\n\n

Hist\u00f3ria 5K UHD<\/strong><\/h2>\n\n\n\n

5K rozl\u00ed\u0161enie bolo p\u00f4vodne vyvinut\u00e9 pre OLED a LED displeje, kde boli pridan\u00e9 \u010fal\u0161ie pixely na zlep\u0161enie kvality obrazu. Pri OLED displejoch bol zaveden\u00fd \u0161tvrt\u00fd biely pixel, aby sa zv\u00fd\u0161ila jasnos\u0165 a pred\u013a\u017eila \u017eivotnos\u0165 farebn\u00fdch pixelov. Napr\u00edklad prv\u00fd OLED telev\u00edzor od Samsungu, S9, uveden\u00fd na trh v roku 2014, mal 5K rozl\u00ed\u0161enie. Rovnako aj spolo\u010dnos\u0165 Sharp pon\u00fakala displeje so \u0161tvrt\u00fdm \u017elt\u00fdm pixelom.<\/p>\n\n\n

D\u00f4le\u017eit\u00e9 je pochopi\u0165, \u017ee farebn\u00fd obraz vo videu je tvoren\u00fd z troch prim\u00e1rnych farieb: \u010dervenej, zelenej a modrej (RGB), ktor\u00e9 spolo\u010dne vytv\u00e1raj\u00fa cel\u00fa \u0161k\u00e1lu odtie\u0148ov. V \u0161tandardnom UHD displeji je horizont\u00e1lne rozl\u00ed\u0161enie (3840) rozdelen\u00e9 na tri \u0161tandardn\u00e9 farby, \u010do vedie k 1280 pixelom na farbu. Av\u0161ak na displejoch so \u0161tyrmi subpixelmi pridanie \u0161tvrt\u00e9ho pixela zni\u017euje po\u010det pixelov pre ka\u017ed\u00fa farbu na 960 (3840 \u00f7 4), \u010do technicky nesp\u013a\u0148a skuto\u010dn\u00e9 UHD \u0161tandardy. Pri zobrazovan\u00ed UHD obsahu na tak\u00fdchto obrazovk\u00e1ch sa ka\u017ed\u00fd \u0161tvrt\u00fd pixel presko\u010d\u00ed, \u010do vedie k ni\u017e\u0161ej kvalite obrazu. Procesor to kompenzuje algoritmami, ktor\u00e9 rekon\u0161truuj\u00fa obraz s men\u0161\u00edm po\u010dtom pixelov.<\/p>\n\n\n\n

Zavedenie 5K displejov s 5120 horizont\u00e1lnymi pixelmi vyrie\u0161ilo tento probl\u00e9m t\u00fdm, \u017ee zachovalo skuto\u010dn\u00fa kvalitu UHD bez toho, aby ch\u00fdbal jedin\u00fd pixel.<\/p>\n\n\n\n
