Isisindo sibulala amaphrojekthi amaningi kunesabelomali.
Izikrini ezisobala zinesisindo3-12 kg/m²futhi gijimani10 mm ubukhulu. Izikrini zendabuko ezinamakhabethe zinesisindo30-50 kg/m²kanye nesilinganiso50-150 mm ukujula. Isakhiwo esiyigugu esinamafasitela angempela ngokuvamile asikwazi ukusekela isisindo se-LED esivamile ngaphandle kokuqiniswa kwensimbi okungacekela phansi izinhlu zamagugu. Izikrini ezibonisa ngale zigibela ngqo endaweni yengilazi yangaphakathi ngaphandle komsebenzi wesakhiwo. Ukufaka kuthatha izinsuku kunezinyanga.
Iketango lezitolo elinangaphambili kwesitolo sengilazi engu-500 likhiphe izikrini ezibonisa ngale kuyo yonke inethiwekhi ngaphandle kokuthinta izakhiwo zesakhiwo. Ukuzama okufanayo ngezikrini ezivamile kuzodinga ubunjiniyela besakhiwo ngokwezifiso kuyo yonke indawo{2}}ububanzi bephrojekthi obubulala iziphakamiso eziningi ngaphambi kokuba zifinyelele ukugunyazwa kokugcina kwesabelomali.
Esikuqhathanisayo Empeleni
Emashumini eminyaka, izikrini zendabuko ze-LED bezikuyo yonke indawo-amabhodi womphumela wenkundla, izimpawu zokudayisa. Basebenza kahle: imibala ekhanyayo, enembile, enokwethenjelwa. Kepha beza ne-tradeoff akekho owayenganjiniyela nxazonke: sonke isikrini sasiwudonga. Ukukhanya okuvinjiwe, ukubukwa okuvinjiwe, kuthathe isikhala.
I-LED ekhanyayo iphenya leyo zibalo. Isigaba esihlukile somkhiqizo ngokuphelele.
Uhlelo lokusebenza lokudayisa yilo olushayela iningi lokukhula okwamanje. Amafasitela ezitolo abelokhu eyizindlu ezithengiswayo. Ufuna ukukhombisa imikhiqizo futhi wenze izinyuso kanyekanye. I-LED yosiko iphoqa ukukhetha-isikrini noma iwindi. I-Transparent LED isusa lokho kukhetha ngokuphelele. Amakhasimende abona okuqukethwe kokuphromotha nokuthengiswayo ngesikhathi esisodwa. Izindawo eziphambili ze-Nike ne-Zara zithole lokhu kusenesikhathi. Lesi simo sokusetshenziswa okukodwa sichaza ukuthi kungani i-LED ebonisa ngale isuka ekubeni nelukuluku lokufuna ukwazi yaya ekucatshangelweni okujulile kwezohwebo phakathi neminyaka emihlanu.
Indlela Akhiwa Ngayo
Izikrini zendabuko zibeka phambili into eyodwa: ukuminyanisa amaphikseli amaningi ngangokunokwenzeka endaweni ethile. Ama-LED chips{1}ukuthiI-SMD (Surface Mount Device), I-COB (I-Chip on Board), noma omdalaI-DIP (Iphakheji Elihlanganisiwe-lomugqa)format-pakishwa ngokuqinile kuma-PCB substrates. Imaski emnyama noma i-epoxy coating imboza yonke into ukuze imanzise ukukhanya kwe-ambient futhi ithuthukise ukugqama.
Imiphumela iyazikhulumela. Amaphaneli e-COB ashaya izilinganiso zokungafani ngenhla20,000:1. Ama-pixel pixel ahamba kahleP0.6mmngezibonisi ze-4K ne-8K. Amayunithi angaphandle aphusha10,000 nithi.
Kodwa izikrini zendabuko ze-LED zivimba u-100% wokukhanya okudlula kuzo. Ziyizindonga zedijithali. Kuhle ukuba nomthelela, kubi kunoma yini lapho udinga ukukubona khona.
Izikrini ezibonisa ngale ziqala ngakolunye uhlangothi. Esikhundleni sokukhulisa isibalo samaphikseli, aklanyelwe ukuvumela ukukhanya kudlule kuyilapho kugcinwa ikhwalithi yesithombe yamukelekile. Izindlela ezintathu eziyinhloko zikhona.Imiklamo{0}esuselwe ku-stripfaka ama-LED chips ku-aluminium encane noma emicu ye-PCB enezikhala phakathi kwazo-ukukhanya kudlula izikhala, kushaya u-60-90% obala kuye ngesikhala.Izinguqulo{0}ezisekelwe kwifilimushumeka ama-micro-ama-LED kuma-Ultra-ama-substrates akhanyayo azacile kakhulu (cishe ugqinsi ongu-4mm, anesisindo esingu-3-6 kg/m²) anamathela ngqo engilazini ekhona.Imiklamo{0}}ehlanganisiwe yengilaziisangweji ama-elementi e-LED phakathi kwezendlalelo zengilazi ezimbili, ukuguqula ingilazi yezakhiwo ibe indawo eboniswayo.
Izikhala eziningi phakathi kwamapheshana zisho ukuthi ukukhanya okuningi kudlula, kodwa amaphikseli ambalwa ngemitha yesikwele. Sonke isikrini esisobala siwukuvumelana phakathi kwalezi zinto ezimbili.
Izinhlobo zokupakisha ze-LED
I-SMD-Idivayisi ye-Surface MountSekungamashumi eminyaka ikhona. Ama-chips angawodwana ezindlini zepulasitiki ezincane, adayiswa kuma-PCB. Ubuchwepheshe buqondile, okuyinzuzo yayo ngqo. Amaketanga okunikezwayo avuthiwe, ochwepheshe bayakwazi ukusebenza ngawo, futhi uma i-LED eyodwa ifa ingashintshwa ngaphandle kokufaka yonke imojula. Lobu ubuchwepheshe be-LED obufakazelwe futhi obuthembeke kakhulu: abukhiqizi-unqenqema, busebenza ngokungaguquki, kubiza-okusebenzayo ukubunakekela. Ukugqama kuhlezi nxazonke1,200-1,800:1. Amayunithi amaningi ahlala cisheAmahora angu-50,000ngaphambi kokuba ukukhanya kwehle ngokuphawulekayo. Kunoma yini engu-P1.2 noma eqinile, i-SMD ihlala iyinketho ezenzakalelayo ngesizathu esihle.
I-COByilapho izinto ziba mnandi-futhi zibiza. I-Chip on Board yeqa izindlu zepulasitiki ngazinye ngokuphelele. Ama-chips amaningi e-LED afakwa aqonde ku-substrate, bese embozwa ngelendlalelo elilodwa le-resin. Ubunjiniyela buzuza i-cascade kusuka lapho: ukushisa kushabalalisa cishe izikhathi ezi-3x kangcono (azikho izindlu zepulasitiki ezibamba ukufudumala), umehluko weqa udlule.20,000:1(leyo ndawo ehlanganisiwe idonsa ukukhanya kwe-ambient ngempumelelo kakhudlwana), futhi ubude bempilo budlulela ngaleAmahora angu-100,000. Iyona kuphela inketho esebenzayo-yezinga eliphezulu elingaphansi kuka-P1.0. I-tradeoff: uma okuthile kwehluleka, yonke imojula idinga ukushintshwa ku$200-300 ngesigameko ngasinye. Futhi izindleko zangaphambili zikhuphuka kakhulu. Ubuchwepheshe bufanela izitudiyo zokusakaza kanye{2}}nezindawo zezinkampani eziphezulu. Imelela ukutshalwa kwezimali okweqile kwendawo yokwamukela izivakashi ehhotela.
Bese kuba khonaI-GOB-I-SMD enento evikelayo. Glue ebhodini. Ubuchwepheshe obufanayo obuyisisekelo, kodwa ngongqimba lweglue optical elimboze indawo ye-LED. Lokhu kunikeza ukuqina okungcono ngokumelene nokuxhumana ngokomzimba kanye nomswakama ngenkathi kugcinwa umnotho wokulungisa we-SMD. Ezinye izihlanganisi zincoma kakhulu{4}ezindaweni zokuthengisa zethrafikhi eziphezulu. Abanye bakubheka njengokungadingekile ezinhlelweni eziningi. Imiphumela iyahlukahluka kuye ngezimo ezithile zokusetshenziswa.
Izikrini eziningi ezibonisa ngale zisebenzisa umugqa oguquliwe{0}osekelwe ku-SMD ukukhweza noma ama-substrates abonisa ngale akhethekile. Amanye amamodeli e-premium asebenzisa izindlela ze-COB{2}}eziyingxube esobala esobala.
Imininingwane Ebalulekile (Naleyo Engenakho)
Akuwona wonke ama-specs afanele ukunakwa ngokulinganayo.
