Ukusebenzisa i-TV yomthengi ngezinjongo zokuthengisa kwenza iwaranti yomkhiqizi ingasebenzi. Amathimba amaningi okuthenga athola lokhu ngemva kokushintshwa kwesibili noma kwesithathu-okuyilapho isisombululo sabo "sesabelomali" sesivele seqe izindleko zephaneli eyodwa yezohwebo.
Igebe lentengo phakathi kwe-TV yomthengi ka-$300 kanye nephaneli ye-LCD yezentengiso engu-$1,200 libukeka libalulekile ku-oda lokuthenga. Eshidini elicacisiwe, umehluko ubonakala umncane: ukulungiswa okufanayo, usayizi wesikrini ofanayo, zombili zifuna ukukhanya kwe-LED. Ukuhlukana kwangempela kubonakala cishe enyangeni yeshumi nane, lapho umthengi-ibanga elibonisayo eligijima amahora ayishumi nambili nsuku zonke endaweni yokuthengisa liqala ukwehluleka noma ukwehlisa isithunzi ngokusobala. Amaphaneli ezohwebo akhiwe amahora angu-50,000 kuya kwangu-100,000 okusebenza okuqhubekayo{11}kodwa leyo nombolo ithatha ukufakwa okufanele nokuphathwa kokushisa, okuyilapho ukuthunyelwa okuningi kungalungile.
Lapho Ubunjiniyela buhluke khona
Izilinganiso zokukhanya zixoxa kuphela ingxenye yendaba. Amaphaneli wabathengi ngokuvamile akhipha ama-nits angu-200-300; ezohwebo-amaphaneli e-LCD e-LCD okudayisa aqala ku-400-700 nits ukuze asetshenziswe endlini futhi afinyelele ku-2,500-5,000 nits wokufakwa okubheke efasiteleni. Uma ilanga lantambama lishaya ingilazi yangaphambili kwesitolo sakho, lokhu akuphathelene nobuhle—ukuthi amakhasimende angakwazi ukufunda amanani akho nhlobo.
Ukuphatha okushisayo kudala ukuhlukana kwangempela. Uma sihlola amasayithi okufaka, umbuzo wokuqala akuwona usayizi wesikrini{1}}ukugeleza komoya. Izinga lokushisa le-junction ye-LED ngaphezu kwama-degree angu-85 linciphisa ukusebenza kahle okukhanyayo ngo-3-5% nge-10℃eyengeziwe. Amaphaneli ezentengiselwano abhekana nalokhu ngamapulangwe angemuva okulahla ukushisa kwe-aluminium aminyene; amayunithi omthengi aweqa lapha ngoba ukusetshenziswa kwekhaya akulokothi kweqe imikhawulo yokushisa. Endaweni yokuthengisa evaliwe ene-HVAC engasebenzi kahle, lo mehluko unquma ukuthi isibonisi sakho siba mnyama yini phakathi namahora ashisa kakhulu ehlobo.
Kukhona ukucaciswa kwabathengi abaningi abangakaze bahlangabezane nakho: I-Tni, izinga lokushisa le-nematic-isotropic transition. Uma izinga lokushisa lephaneli lidlula lo mkhawulo, amabala amakhulu amnyama avela esikrinini. Ama-LCD ezentengiso-ezinga lezimboni asebenzisa{4}}ukwakheka kwekristalu ye-Tni ewuketshezi ephezulu ikakhulukazi ngoba ukufakwa kwamafasitela{5}}okubheke ezitolo ezindaweni ezishisayo kuzophusha amaphaneli ajwayelekile adlule umkhawulo wawo ehlobo lokuqala.
I-ROI: Lapho Izinombolo Zivela Ezindabeni
Izitolo zekhemisi ezingu-30-esisebenze nazo eMidwest zilandele u-11% wokuphakamisa izinto eziphromothiwe phakathi nekota yokuqala{4}}ngokuzungeziswa kokuqukethwe kwamasonto onke nokubekwa lapho usukhokha. Umthengisi onemfashini esheshayo onesibalo sesikrini esiphindwe kabili wabona umthelela ongenakulinganiswa ngoba okuqukethwe kokuphromotha akuzange kubuyekezwe ngemva kweviki lokuqalisa. Isigaba sehadiwe efanayo, imiphumela ephambene.
Izikhathi zokukhokha zokuthengisa izimpawu zedijithali ngokuvamile ziwela phakathi kwezinyanga eziyi-8 neziyi-18 lapho ukuphathwa kokuqukethwe kusebenza. Okuguquguqukayo okushintshashintshayo kulobu bubanzi: inani lokwenziwe (izitolo ezithengisa izinto ezilula zidinga ukuthengwa okuthonyeka kakhulu kunezitolo zefenisha ukuze zibe nomthelela wedola elifanayo), indlela yokulinganisa (imali yokulinganisa yezinto ezithuthukisiwe ibonisa amaphesenti amangalisayo; ukuthengiswa kwesitolo kukonke kubonisa amadijithi angawodwa anesizotha), kanye nesiyalo sokuvuselela.
Ukwenyuka kokubandakanyeka okungama-25-35% okukhulunywe ngakho emibikweni yemboni kumele ukuthunyelwa lapho othile empeleni ephethe okuqukethwe. Sicaphuna u-8-15% njengokuqagela kokuhlela kumakhasimende angakulungele ukwenza izinsiza ezinikelwe ekuzungezweni kokuqukethwe-kuyalandela, futhi kusaphuma ipensela phakathi neminyaka emibili emithonjeni eminingi yokudayisa.
I-TCO Yeminyaka Emihlanu{{0}: Izibalo Ezivala Ingxoxo
| I-Cost Element | I-TV yabathengi | I-LCD yezentengiso |
|---|---|---|
| Ihadiwe yokuqala | $300/iyunithi | $1,200/iyunithi |
| Ukushintshwa okungaphezu kweminyaka emi-5 | 2-3 amayunithi + abasebenzi | 0 |
| Izindleko zehardware yeminyaka emi-5 | $1,100-1,800 | $1,200 |
| Ukufakwa kwewaranti | Ayisebenziswanga ukusetshenziselwa ukuhweba | Iminyaka engu-3 ejwayelekile |
| Umehluko wamandla | Isisekelo | 15-25% ngaphansi |
Iphaneli yezohwebo ibiza kancane kuso sonke isimo lapho usebenzisa khona izikrini ngaphezu kwamahora ayisithupha nsuku zonke. Emsebenzini-wamahora angu-8, i-crossover iyenzeka cishe inyanga engu-30. Emahoreni ayishumi nambili, yinyanga engu-18. Siyekile ukucaphuna ezinye izindlela zabathengi kunoma yikuphi ukuhlelwa kweklayenti okungaphezu kwezinyanga ezingu-24-zokusetshenziswa kwezinyanga-umthwalo wosekelo uwodwa awuwufanele umkhawulo.
Ukwehluleka Ukufaka Siyabona Ngempela
Amaphesenti angamashumi ayisithupha ezingcingo zesevisi yethu ezinsukwini zokuqala ezingu-90 alandelela ekucushweni, hhayi ihadiwe. Okuvame kakhulu: ukungafani komthombo wokufakwayo lapho izifaki zixhuma i-HDMI embobeni 2 futhi zilungiselele isidlali semidiya sembobo 1. Ukulebula izimbobo ekufakweni kuqeda lesi sigaba ngokuphelele. Manje sesifaka imibhalo yemephu yembobo njengokulethwa okujwayelekile{5}}akubizi lutho futhi inciphisa umthamo wesevisi yangaphambi kwesikhathi ngesigamu.
Ukuhlelwa kwesekethe yamandla kwehluleka cishe kaningi ezindaweni zokubuyiselwa imali. Izibonisi zezimpawu-zezentengiso ze-lcd zidweba u-2.5-4.5 amps ngeyunithi ngayinye ekukhanyeni okugcwele. Hlanganisa izibonisi ezine kusekethe engu-15A ngaphandle kokubala inani eliphakeme kakhulu futhi uthola ukucima kukagesi okubukeka njengokuhluleka kwehadiwe kodwa akunjalo. Ikhodi kagesi ye-NEC icacisa u-80% omkhulu womthwalo osimeme-incazelo elandelwa abahlanganisi be-AV kodwa osonkontileka abavamile bavame ukukushaya indiva lapho "bengeza izikrini ezimbalwa."
Izikhala ezishisayo azinakwa ezindaweni zokuthengisa eziqinile. Sibhale imibukiso ehlulekayo ezinyangeni eziyi-18 obekumele ithathe iminyaka eyisikhombisa, ngenxa yezinqumo ezikhulayo ezenziwe ukonga amayintshi amane esikhala. Ukuhlolwa kwethu kwesayithi okujwayelekile manje kuhlanganisa ukuthwebula izithombe ezishisayo phakathi namahora okusebenza aphezulu{3}}isinyathelo esengeziwe esivimbele izingxabano ezintathu zesiqinisekiso onyakeni odlule kuphela.
I-Supplier Ecosystem: Esikuncomayo Empeleni
Ngokuthengwa kwephaneli yesibonisi se-lcd esitolo esidayisa yonke impahla, isinqumo siza ngokuthi ufuna ukuguquguquka kwe-CMS noma ukuhlanganiswa kwe-ecosystem. I-MagicINFO yakwaSamsung ikuvalela ku-hardware yayo kodwa yenza{1}}ukuphathwa kwamasayithi kube lula. Izingxenyekazi zenkampani yangaphandle-njenge-BrightSign zidinga umsebenzi owengeziwe wokuhlanganisa kodwa zikuvumela ukuthi uhlanganise abathengisi bephaneli ngokusekelwe ezimfuneko ezithile zesayithi-izindawo ezibheke ewindini{5}}zingase zidinge ukukhanya okuphakeme kunasemuva--zesitolo, futhi ukuphoqelela umdayisi oyedwa kuzo zombili izidrayivu izindleko ezingadingekile.
Sicacisa i-Samsung ngamaklayenti anezinsiza ze-IT ezizinikele ezifuna umphimbo owodwa uminyaniswe. Sicacisa ukufakwa okuxubile -ne-CMS yenkampani yangaphandle kumakhasimende abeka phambili izindleko zezingxenyekazi zekhompuyutha futhi abe nobudlelwano bokuhlanganisa ukuze alawule ubunzima. Ayikho impendulo evamile-kodwa kunempendulo engalungile, ekhetha ngokusekelwe enanini lephaneli iyodwa kanye nokuthola imodeli yokubhaliselwe ye-CMS ezinyangeni eziyisithupha kamuva.
