Kugwiritsa ntchito ma TV ogula pazinthu zamalonda kumalepheretsa chitsimikizo cha wopanga. Magulu ambiri ogula zinthu amapeza izi pambuyo polowa m'malo wachiwiri kapena wachitatu-panthawi yomwe njira yawo ya "bajeti" yadutsa kale mtengo wa gulu limodzi lazamalonda.
Kusiyana kwamitengo pakati pa $300 ogula TV ndi $1,200 gulu lamalonda la LCD likuwoneka lofunikira pakugula. Pa pepala lodziwika bwino, kusiyana kumawoneka kocheperako: kusamvana komweko, kukula kwazenera kofananira, onse amati kuyatsa kwa LED. Kulekanitsa kwenikweni kumawonekera pafupifupi mwezi wakhumi ndi zinayi, pamene ogula{{5}magiredi amagetsi akuyenda maola khumi ndi awiri tsiku lililonse m'malo ogulitsa amayamba kulephera kapena kutsika mowonekera. Mapanelo azamalonda amapangidwa kwa maola 50,000 mpaka 100,000 akugwira ntchito mosalekeza{11}koma nambalayi imatengera kuyika koyenera komanso kuyang'anira kutentha, komwe ndi komwe ntchito zambiri zimalakwika.
Kumene Engineering Imasiyana
Kuwala kumangonena gawo lokha la nkhaniyi. Makanema ogula nthawi zambiri amatulutsa 200-300 nits; malonda-mapanelo owonetsera ma LCD a grade 400-700 nits kuti agwiritse ntchito m'nyumba ndikufikira 2,500-5,000 nits poyika mawindo. Dzuwa likamadzafika pagalasi lakutsogolo kwa sitolo yanu, izi sizikukhudzana ndi kukongola-ndi ngati makasitomala angathe kuwerengera mitengo yanu nkomwe.
Kuwongolera kutentha kumapanga kulekanitsa kwenikweni. Tikawunika malo oyikapo, funso loyamba si kukula kwa zenera{1}}ndi kayendedwe ka mpweya. Kutentha kwa mphambano ya LED pamwamba pa 85 digiri kumadula mphamvu yowala ndi 3-5% pa madigiri 10 owonjezera. Mapanelo azamalonda amathana ndi izi ndi zitsulo zokulirapo za aluminiyamu zowotcha kutentha; mayunitsi ogula amadumpha apa chifukwa kugwiritsa ntchito kunyumba sikumadutsa malire amafuta. M'malo ogulitsa osindikizidwa osayenda bwino a HVAC, kusiyana kumeneku kumatsimikizira ngati chiwonetsero chanu chizida nthawi yachilimwe.
Pali zomwe ogula ambiri sakumana nazo: Tni, kutentha kwa nematic-isotropic transition. Kutentha kwa gululi kukapitilira malire awa, mawanga akulu akuda amawonekera pazenera. Ma LCD a zamalonda aku Industrial- amagwiritsa ntchito-Tni liquid crystal formulations yokwera makamaka chifukwa mawindo-oyang'anizana ndi malo osungiramo malo otentha amatha kupitirira malire ake m'chilimwe choyamba.
ROI: Kumene Manambala Amachokera Kuzinthu
Malo 30-ogulitsa mankhwala omwe tidagwira nawo ntchito ku Midwest adatsata 11% kukweza zinthu zokwezedwa m'gawo loyamba{4}}ndikusinthana zinthu mlungu uliwonse ndikuziika polipira. Wogulitsa zinthu zotsogola kwambiri yemwe ali ndi chiwerengero chowonekera kawiri adawona kuti palibe chomwe chingayesedwe chifukwa zotsatsa sizinasinthidwe pambuyo pa sabata yotsegulira. Gulu la hardware lomwelo, zotsatira zosiyana.
Nthawi zobweza zama digito ogulitsa nthawi zambiri zimakhala pakati pa miyezi 8 ndi 18 pomwe kasamalidwe kazinthu kakugwira ntchito. Zosintha zomwe zimayenda mosiyanasiyana: mtengo wamalonda (malo ogulitsira amafunikira kugulidwa kochulukira kuposa ogulitsa mipando kuti akhudzidwe ndi dola imodzi), njira yofananira (kuyezera kukwezedwa kwazinthu zokwezedwa kumawonetsa kuchuluka kwakukulu; kugulitsa konse kwa sitolo kumawonetsa manambala ochepa), ndikuwongolera mwambo.
Kuwonjezeka kwa 25-35% ya kutanganidwa komwe kwatchulidwa m'malipoti amakampani kumayimira kutumiza komwe wina amayang'anira zomwe zili. Timatchula 8-15% ngati lingaliro lokonzekera makasitomala omwe sali okonzeka kudzipereka kuti agwiritse ntchito kasinthasintha-ndiwosamala, ndipo amatulukabe mkati mwa zaka ziwiri pazotsatira zambiri zamalonda.
