V polovici 2000-tych rokov bol Sharp l\u00eddrom vo v\u00fdrobe ve\u013ek\u00fdch telev\u00edznych panelov a ovl\u00e1dal viac ne\u017e polovicu trhu s LCD panelmi. Tento segment sa stal strategickou prioritou spolo\u010dnosti a Sharp do jeho rozvoja v\u00fdrazne investoval. Na za\u010diatku 2010-tych rokov predstavilo v\u00fdskumno-v\u00fdvojov\u00e9 oddelenie spolo\u010dnosti revolu\u010dn\u00fd koncept: pridanie \u0161tvrt\u00e9ho subpixela k \u0161tandardnej trojfarebnej matici. T\u00e1to technol\u00f3gia sa naz\u00fdvala YRGB alebo RGBY, no verejnosti bola zn\u00e1ma pod komer\u010dn\u00fdm n\u00e1zvom Quattron.<\/p>\n\n\n\n
Podstatou tejto technol\u00f3gie bolo pridanie \u017elt\u00e9ho subpixela k tradi\u010dn\u00fdm \u010derven\u00e9mu, zelen\u00e9mu a modr\u00e9mu subpixelu. Displeje s touto \u0161trukt\u00farou mali viacer\u00e9 v\u00fdhody \u2013 najm\u00e4 lep\u0161\u00ed jas pri zobrazen\u00ed odtie\u0148ov poko\u017eky, ktor\u00e9 prirodzene obsahuj\u00fa \u017elt\u00e9 zlo\u017eky. To tie\u017e prispievalo k zv\u00fd\u0161eniu celkov\u00e9ho jasu panela.<\/p>\n\n\n\n
Z\u00e1rove\u0148 v\u0161ak mali telev\u00edzory Sharp z tohto obdobia cite\u013en\u00e9 obmedzenie \u2013 relat\u00edvne n\u00edzky maxim\u00e1lny jas. I\u0161lo o vedom\u00fd technick\u00fd kompromis s cie\u013eom dosiahnu\u0165 lep\u0161\u00ed kontrast.<\/p>\n\n\n\n
Pou\u017eitie \u0161tyroch subpixelov si vy\u017eadovalo integr\u00e1ciu dodato\u010dn\u00e9ho modulu na spracovanie obrazu, preto\u017ee \u017elt\u00fd subpixel musel by\u0165 riaden\u00fd samostatne. V\u00fdroba t\u00fdchto panelov bola drah\u0161ia a preto sa pou\u017e\u00edvali len v modeloch vy\u0161\u0161ej triedy.<\/p>\n\n\n\n
Napriek svojim v\u00fdhod\u00e1m \u010delila technol\u00f3gia YRGB viacer\u00fdm v\u00fdzvam. Hlavn\u00fdm probl\u00e9mom boli vysok\u00e9 v\u00fdrobn\u00e9 n\u00e1klady. Pridanie \u0161tvrt\u00e9ho subpixela a v\u00fdvoj \u0161pecializovanej T-CON dosky na riadenie obrazu v\u00fdznamne zvy\u0161ovali n\u00e1klady. Ke\u010f spolo\u010dnosti Samsung a LG otvorili nov\u00e9 tov\u00e1rne na LCD panely, dopyt po paneloch Sharp za\u010dal klesa\u0165. V roku 2014 Sharp opustil segment v\u00fdroby telev\u00edzorov, \u010d\u00edm stratil hlavn\u00fd trh pre tieto panely. V\u00fdroba s\u00edce e\u0161te ur\u010dit\u00fd \u010das pokra\u010dovala, ale bez v\u00e4\u010d\u0161ieho \u00faspechu, preto\u017ee panely sa pou\u017e\u00edvali najm\u00e4 v telev\u00edzoroch vyr\u00e1ban\u00fdch tret\u00edmi stranami pod zna\u010dkou Sharp.<\/p>\n\n\n\n
V roku 2024 spolo\u010dnos\u0165 Sharp ofici\u00e1lne ukon\u010dila v\u00fdrobu ve\u013ek\u00fdch LCD panelov a 21. augusta zatvorila svoj z\u00e1vod v meste Sakai. Spolo\u010dnos\u0165 ozn\u00e1mila pl\u00e1n preda\u0165 v\u0161etky zost\u00e1vaj\u00face z\u00e1soby do marca 2025, \u010do nazna\u010duje, \u017ee vopred vyrobili zna\u010dn\u00e9 mno\u017estvo panelov. T\u00fdmto sa skon\u010dila \u00e9ra \u0161tvorfarebn\u00fdch LCD panelov Sharp \u2013 jedn\u00e9ho z najambici\u00f3znej\u0161\u00edch a najcharakteristickej\u0161\u00edch technologick\u00fdch projektov spolo\u010dnosti.<\/p>\n","protected":false},"excerpt":{"rendered":"
