Modern\u00e9 LED telev\u00edzory s\u00fa postaven\u00e9 na LCD paneloch s LED podsvieten\u00edm, ktor\u00e9 nahradilo star\u0161ie a menej efekt\u00edvne CCFL lampy. LED di\u00f3dy vy\u017earuj\u00fa svetlo, ktor\u00e9 prech\u00e1dza bunkami naplnen\u00fdmi kvapaln\u00fdmi kry\u0161t\u00e1lmi v troch z\u00e1kladn\u00fdch farb\u00e1ch: \u010derven\u00e1, zelen\u00e1 a modr\u00e1.<\/p>\n\n\n\n
Ke\u010f sa aplikuje nap\u00e4tie, kvapaln\u00e9 kry\u0161t\u00e1ly menia svoju polohu. T\u00e1to zmena ovplyv\u0148uje polariz\u00e1ciu svetla, ktor\u00e9 nimi prech\u00e1dza, \u010do umo\u017e\u0148uje prep\u00fa\u0161\u0165anie r\u00f4zneho mno\u017estva svetla. V\u00fdsledkom je, \u017ee sa na obrazovke vytvor\u00ed obraz.<\/p>\n\n\n\n
LED telev\u00edzory poskytuj\u00fa ostr\u00fd a detailn\u00fd obraz, ale maj\u00fa obmedzenia v kontraste a reprodukcii \u010diernej. Preto\u017ee podsvietenie je v\u017edy zapnut\u00e9, svetlo m\u00f4\u017ee presakova\u0165 okolo okrajov pixelov, \u010do znemo\u017e\u0148uje dosiahnutie dokonal\u00e9ho \u010dierneho.<\/p>\n\n\n\n
\u010eal\u0161ou gener\u00e1ciou LED telev\u00edzorov boli QLED telev\u00edzory. QLED je v podstate marketingov\u00fd term\u00edn, ktor\u00fd popisuje vylep\u0161en\u00e9 LED panely. Tieto telev\u00edzory pou\u017e\u00edvaj\u00fa \u010distej\u0161ie pixelov\u00e9 materi\u00e1ly na zlep\u0161enie kvality obrazu, hoci z\u00e1kladn\u00e1 technol\u00f3gia zost\u00e1va rovnak\u00e1 ako pri \u0161tandardn\u00fdch LED telev\u00edzoroch.<\/p>\n\n\n\n
V\u00fdrobcovia st\u00e1le experimentuj\u00fa s r\u00f4znymi typmi podsvietenia \u2013 Edge LED, Direct LED, Mini LED a Micro LED. Av\u0161ak ve\u013ek\u00e9 spolo\u010dnosti, ako LG<\/strong> a Samsung<\/strong>, nepova\u017euj\u00fa tradi\u010dn\u00e9 LED displeje za perspekt\u00edvne z dlhodob\u00e9ho h\u013eadiska a predali svoje LCD tov\u00e1rne \u010d\u00ednskym firm\u00e1m.<\/p>\n\n\n\n OLED technol\u00f3gia (organick\u00e1 sveteln\u00e1 di\u00f3da) funguje inak. Ka\u017ed\u00fd pixel vy\u017earuje vlastn\u00e9 svetlo, \u010d\u00edm sa eliminuje potreba \u010fal\u0161ieho podsvietenia. Ke\u010f\u017ee ka\u017ed\u00fd pixel m\u00f4\u017ee by\u0165 \u00faplne vypnut\u00fd, OLED telev\u00edzory poskytuj\u00fa dokonal\u00fa \u010diernu, v\u00fdnimo\u010dn\u00fd kontrast a presn\u00e9 farebn\u00e9 podanie.<\/p>\n\n\n\n OLED panely s\u00fa ten\u0161ie a \u013eah\u0161ie ako LED panely a poskytuj\u00fa vy\u0161\u0161iu kvalitu obrazu.

Tieto materi\u00e1ly sa degraduj\u00fa r\u00f4znou r\u00fdchlos\u0165ou, \u010do vedie k nerovnomern\u00e9mu opotrebeniu a krat\u0161ej \u017eivotnosti panelu. Napriek tomuto probl\u00e9mu investovali LG<\/strong> a Samsung<\/strong> do v\u00fdroby OLED.<\/p>\n\n\n\n V roku 2013 Samsung predstavil svoj prv\u00fd ve\u013ek\u00fd OLED telev\u00edzor, model S9, ale model sa komer\u010dne neosved\u010dil. V d\u00f4sledku toho Samsung do\u010dasne pozastavil v\u00fdvoj OLED. LG pokra\u010dovala vo v\u00fdvoji technol\u00f3gie a v roku 2016 uviedla na trh svoj prv\u00fd OLED telev\u00edzor.<\/p>\n\n\n\n Aby sa zn\u00ed\u017eilo riziko vyp\u00e1lenia obrazu, LG vyvinula WRGB panely, ktor\u00e9 obsahuj\u00fa biely subpixel, \u010d\u00edm sa zni\u017euje z\u00e1\u0165a\u017e farebn\u00fdch pixelov. \u010eal\u0161\u00edm vylep\u0161en\u00edm, ktor\u00e9 v\u00fdrazne zv\u00fd\u0161ilo jas, bolo pou\u017eitie mikroskopick\u00fdch \u0161o\u0161oviek, ktor\u00e9 presmerov\u00e1vaj\u00fa svetlo z vn\u00fatra panela smerom von. Tieto vylep\u0161en\u00e9 panely nes\u00fa ozna\u010denie Evo.<\/p>\n\n\n\n Nesk\u00f4r sa Samsung vr\u00e1til na OLED trh s in\u00fdm pr\u00edstupom. Ich panely pou\u017e\u00edvaj\u00fa v\u00e4\u010d\u0161ie RGB pixely s organick\u00fdmi di\u00f3dami, ktor\u00e9 vy\u017earuj\u00fa \u0161pecifick\u00e9 farby, doplnen\u00e9 farebn\u00fdmi filtrami na vytvorenie hlavnej farebnej palety.<\/p>\n\n\n\n O\u010dak\u00e1va sa, \u017ee OLED zostane dominantnou technol\u00f3giou vo v\u00fdrobe telev\u00edzorov v nasleduj\u00facich rokoch. Z\u00e1rove\u0148 sa n\u00e1klady na v\u00fdrobu OLED v posledn\u00fdch rokoch v\u00fdrazne zn\u00ed\u017eili, \u010do rob\u00ed tieto telev\u00edzory pre spotrebite\u013eov \u010doraz atrakt\u00edvnej\u0161ie.<\/p>\n\n\n\n Bezpochyby bud\u00facnos\u0165 patr\u00ed OLED. Napriek p\u00fatav\u00fdm n\u00e1zvom ako QLED a Micro LED, LED technol\u00f3gia prakticky vy\u010derpala svoj potenci\u00e1l. Aj pri rozsiahlej kampani \u010d\u00ednskych v\u00fdrobcov na podporu Micro LED v roku 2026 m\u00e1 technol\u00f3gia sama o sebe viacero technick\u00fdch obmedzen\u00ed, ktor\u00e9 br\u00e1nia LED dosiahnu\u0165 \u00farove\u0148 OLED. Hlavn\u00fdm d\u00f4vodom je absencia skuto\u010dnej \u010diernej.<\/p>\n\n\n\n OLED panely vyrie\u0161ili mnoh\u00e9 probl\u00e9my s vyp\u00e1len\u00edm obrazu, ktor\u00e9 boli charakteristick\u00e9 pre predch\u00e1dzaj\u00face verzie. V\u00fdrobcovia zaviedli \u00fadr\u017ebov\u00e9 syst\u00e9my pre OLED panely \u2013 programy, ktor\u00e9 kontroluj\u00fa \u010dinnos\u0165 pixelov. Pri spusten\u00ed tak\u00fdto program analyzuje aktu\u00e1lnu spotrebu pixelov a vykon\u00e1va \u00fapravy. To odstra\u0148uje zvy\u0161kov\u00e9 obrazy a predl\u017euje \u017eivotnos\u0165 panela.<\/p>\n\n\n\n Ni\u017e\u0161ie v tabu\u013eke m\u00f4\u017eete vidie\u0165 podrobn\u00e9 rozdiely medzi telev\u00edzormi.<\/strong><\/p>\n\n\n\n Pred tridsiatimi rokmi boli farebn\u00e9 telev\u00edzory s CRT obrazovkami pova\u017eovan\u00e9 za \u0161pi\u010dkov\u00fa technol\u00f3giu.
