V roku 2021 spolo\u010dnos\u0165 LG predstavila svoje nov\u00e9 displeje Evo OLED. Spolo\u010dnos\u0165 tvrd\u00ed, \u017ee t\u00e1to technol\u00f3gia pos\u00fava kvalitu obrazu na nov\u00fa \u00farove\u0148, ale tak\u00e9to vyhl\u00e1senia pre be\u017en\u00e9ho div\u00e1ka ve\u013ea neznamenaj\u00fa. V skuto\u010dnosti je Evo OLED v\u00fdsledkom kombin\u00e1cie pokrokov\u00fdch materi\u00e1lov s v\u00fdznamn\u00fdmi technick\u00fdmi vylep\u0161eniami, \u010d\u00edm vznikla nov\u00e1 gener\u00e1cia OLED displejov, ktor\u00e9 pon\u00fakaj\u00fa skuto\u010dne lep\u0161\u00ed v\u00fdkon \u2013 a to je to, o \u010dom s\u00fa displeje Evo v skuto\u010dnosti.<\/p>\n\n\n\n
K\u013e\u00fa\u010dovou v\u00fdhodou displejov LG OLED Evo je vy\u0161\u0161\u00ed jas. Tradi\u010dn\u00e9 panely OLED zvy\u010dajne dosahuj\u00fa jas okolo 800 nitov, zatia\u013e \u010do OLED Evo ho zvy\u0161uje pribli\u017ene o 20 %, \u010d\u00edm sa maxim\u00e1lny jas bl\u00ed\u017ei k 1000 nitom. V\u010faka tomu s\u00fa obrazy \u010ditate\u013enej\u0161ie v jasn\u00fdch miestnostiach a v\u00fdrazne sa zlep\u0161uje v\u00fdkon HDR, kde s\u00fa jasn\u00e9 \u010dasti obrazu \u017eiv\u0161ie a p\u00f4sobivej\u0161ie.<\/p>\n\n\n\n
Teoreticky je zv\u00fd\u0161enie jasu jednoduch\u00e9: sta\u010d\u00ed pou\u017ei\u0165 vy\u0161\u0161ie nap\u00e4tie a pixely svietia jasnej\u0161ie. V praxi sa technol\u00f3gia OLED spolieha na organick\u00e9 materi\u00e1ly, ktor\u00e9 sa pri vy\u0161\u0161om nap\u00e4t\u00ed r\u00fdchlej\u0161ie rozkladaj\u00fa. Skuto\u010dnou v\u00fdzvou je preto zv\u00fd\u0161enie jasu bez obetovania \u017eivotnosti panelu.<\/p>\n\n\n\n
Spolo\u010dnos\u0165 LG tento probl\u00e9m vyrie\u0161ila pou\u017eit\u00edm nov\u00fdch OLED materi\u00e1lov vyvinut\u00fdch spolo\u010dnos\u0165ou DuPont, ktor\u00e1 nahradila jej predch\u00e1dzaj\u00faceho dod\u00e1vate\u013ea, japonsk\u00fa spolo\u010dnos\u0165 Idemitsu. Po rozsiahlom testovan\u00ed spolo\u010dnos\u0165 LG zistila, \u017ee materi\u00e1ly spolo\u010dnosti DuPont pon\u00fakaj\u00fa lep\u0161\u00ed v\u00fdkon a v\u00e4\u010d\u0161iu dlhodob\u00fa stabilitu. K\u013e\u00fa\u010dovou inov\u00e1ciou je tu pou\u017eitie \u0165a\u017ek\u00e9ho vod\u00edka, alebo deut\u00e9ria, namiesto be\u017en\u00e9ho vod\u00edka. Deut\u00e9rium v\u00fdrazne zlep\u0161uje odolnos\u0165 modr\u00fdch OLED prvkov \u2013 najslab\u0161ieho \u010dl\u00e1nku v OLED paneloch \u2013 a umo\u017e\u0148uje im pracova\u0165 pri vy\u0161\u0161\u00edch nap\u00e4tiach. Tento prelom umo\u017enil dosiahnu\u0165 vy\u0161\u0161iu \u00farove\u0148 jasu v OLED Evo displejoch.<\/p>\n\n\n\n
\u010eal\u0161\u00edm d\u00f4le\u017eit\u00fdm vylep\u0161en\u00edm je pou\u017eitie mikrozrkadlov\u00fdch \u0161trukt\u00far v bl\u00edzkosti pixelov. V konven\u010dn\u00fdch OLED paneloch sa \u010das\u0165 generovan\u00e9ho svetla str\u00e1ca vn\u00fatri displeja v d\u00f4sledku rozptylu a absorpcie. Mikrozrkadl\u00e1 presmeruj\u00fa toto inak nevyu\u017eit\u00e9 svetlo smerom k div\u00e1kovi, \u010d\u00edm zvy\u0161uj\u00fa vn\u00edman\u00fd jas bez zv\u00fd\u0161enia spotreby energie.<\/p>\n\n\n\n
Predch\u00e1dzaj\u00face gener\u00e1cie OLED obrazoviek mohli tie\u017e \u010dasom vykazova\u0165 farebn\u00e9 posuny, \u010dasto nadob\u00fadali \u010dervenkast\u00fd odtie\u0148. Tento efekt bol sp\u00f4soben\u00fd najm\u00e4 r\u00fdchlej\u0161\u00edm starnut\u00edm modr\u00fdch OLED materi\u00e1lov. Vylep\u0161en\u00e9 materi\u00e1ly a optimalizovan\u00fd dizajn panelov pou\u017eit\u00fdch v OLED Evo displejoch v\u00fdrazne zni\u017euj\u00fa tento probl\u00e9m a pom\u00e1haj\u00fa udr\u017ea\u0165 farebn\u00fa presnos\u0165 po dlh\u0161iu dobu.<\/p>\n\n\n\n
Stru\u010dne povedan\u00e9, OLED Evo nie je len jasnej\u0161\u00ed \u2013 je to efekt\u00edvnej\u0161ia a odolnej\u0161ia evol\u00facia technol\u00f3gie OLED, ktor\u00e1 poskytuje vylep\u0161en\u00fa kvalitu obrazu a z\u00e1rove\u0148 zachov\u00e1va dlhodob\u00fa spo\u013eahlivos\u0165.<\/p>\n\n\n\n
Spolo\u010dnos\u0165 LG prv\u00fdkr\u00e1t predstavila svoje telev\u00edzory OLED Evo s\u00e9ri\u00ed W a G v roku 2021, pri\u010dom spo\u010diatku vyr\u00e1bala tieto panely len v troch ve\u013ekostiach: 55, 65 a 77 palcov. Do roku 2026 sa ponuka panelov v\u00fdrazne roz\u0161\u00edrila a spolo\u010dnos\u0165 LG vyr\u00e1bala panely OLED Evo vo ve\u013ekostiach 42, 48, 55, 65, 77, 83 a 97 palcov.<\/p>\n\n\n\n
Odvtedy bolo uveden\u00fdch na trh nieko\u013eko gener\u00e1ci\u00ed panelov Evo. V\u00e4\u010d\u0161ina v\u00fdvoja sa zameriavala na vylep\u0161enie vrstvy MLA (Micro Lens Array) a pred\u013a\u017eenie \u017eivotnosti panelu. \u010eal\u0161\u00edm d\u00f4le\u017eit\u00fdm m\u00ed\u013enikom bol pribl\u00ed\u017eenie sa OLED displejov k hranici 100 palcov. Spolo\u010dnos\u0165 LG uviedla na trh 97-palcov\u00e9 panely, ale ich cena zost\u00e1va extr\u00e9mne vysok\u00e1: tak\u00e9to panely s\u00fa nieko\u013ekon\u00e1sobne drah\u0161ie ako 83-palcov\u00e9 panely. Ak 83-palcov\u00fd telev\u00edzor stoj\u00ed pribli\u017ene 70 USD za palec, 97-palcov\u00fd telev\u00edzor m\u00f4\u017ee st\u00e1\u0165 pribli\u017ene 250 USD za palec. To znamen\u00e1, \u017ee ke\u010f si k\u00fapite 97-palcov\u00fd telev\u00edzor, zaplat\u00edte pribli\u017ene 20 000 USD za 14 palcov.<\/p>\n","protected":false},"excerpt":{"rendered":"
