Izikrini ze-LED ezibonisa ngale, njengeminye imikhiqizo kagesi, zinempilo yonke. Nakuba ukuphila kwethiyori kwe-LED kungamahora angu-100,000, kungasebenza iminyaka engaphezu kwengu-11 ngokusho kwamahora angu-24 ngosuku, izinsuku ezingu-365 ngonyaka, kodwa isimo sangempela kanye nedatha yethiyori kubi kakhulu. Ngokwezibalo, impilo yesikrini se-LED esisobala emakethe ngokuvamile yiminyaka engu-4 ~ 8, izikrini ze-LED ezibonisa izinto ezingasetshenziswa iminyaka engaphezu kwe-8 zibe zinhle kakhulu. Ngakho-ke, impilo yesikrini se-LED esobala amahora ayi-100,000, okufinyelelwa kahle. Esimeni sangempela, kuhle ukusebenzisa amahora angama-50,000.
Izinto ezithinta impilo yesikrini se-LED esibonisa ngale izinto zangaphakathi nangaphandle. Izici zangaphakathi zifaka phakathi ukusebenza kwezingxenye ze-peripheral, ukusebenza kwemishini ekhipha ukukhanya kwe-LED, kanye nokumelana nokukhathala kwemikhiqizo. Imvelo yangaphandle inendawo yokusebenza yesikrini se-LED esobala.
1. Umthelela wezinto ezisemaphethelweni
Ngokungeziwe kumadivayisi okukhanyisa kwe-LED, izikrini ze-LED ezibonisa ngale zisebenzisa nezinye izakhi eziningi ezizungezile, okuhlanganisa amabhodi wesifunda, izindlu zepulasitiki, izinto zamandla ezishintshayo, izixhumi, i-chassis, njll., noma iyiphi inkinga nganoma iyiphi ingxenye, ingaholela empilweni yesikrini esibonisa ngale. nciphisa. Ngakho-ke, impilo ende kakhulu yesibonisi esisobala inqunywa impilo yengxenye ebalulekile eyimfushane kakhulu. Isibonelo, i-LED, i-switching power supply, kanye ne-casing yensimbi konke kukhethwa ngokwezinga leminyaka engu-8, futhi ukusebenza kwenqubo yokuzivikela yebhodi lesifunda kungasekela umsebenzi wayo iminyaka engu-3 kuphela. Ngemva kweminyaka engu-3, izolimala ngenxa yokugqwala, khona-ke singathola kuphela ucezu lweminyaka emi-3 yesikrini esisobala impilo yonke.
2. Umthelela wokusebenza kwedivayisi yokukhanyisa kwe-LED
Ubuhlalu besibani se-LED buyingxenye ebaluleke kakhulu futhi esobala yesikrini esibonisa ngale. Ngobuhlalu besibani se-LED, izinkomba ezilandelayo ikakhulukazi: izici zokuncisha, izici zokungangeni kwamanzi komhwamuko, nokumelana ne-UV. Uma umenzi wesikrini se-LED ebonisa izinto ehlola ukusebenza kobuhlalu besibani se-LED, sizosetshenziswa esikrinini esibonisa ngale, okuzoholela enanini elikhulu lezingozi zekhwalithi futhi kuthinte kabi impilo yesikrini se-LED esisobala.
3. Umthelela wokukhathala komkhiqizo
Ukusebenza okuvimbela ukukhathala kwemikhiqizo yesikrini se-LED esobala kuncike kwinqubo yokukhiqiza. Ukusebenza okulwa nokukhathala kwemojuli okwenziwa inqubo yokwelapha enobufakazi obuthathu obumpofu kunzima ukuqinisekiswa. Lapho izinga lokushisa nomswakama kushintsha, indawo evikelayo yebhodi lesifunda izoqhekeka, okuholela ekunciphiseni kokusebenza kokuzivikela.
Ngakho-ke, inqubo yokukhiqiza yesikrini se-LED esisobala nayo iyisici esibalulekile ekunqumeni impilo yesikrini esisobala. Izinqubo zokukhiqiza ezihilelekile ekukhiqizweni kwesikrini esisobala zifaka phakathi: ukugcinwa kwengxenye kanye nenqubo yokwelashwa kusengaphambili, inqubo yokushisela esithandweni somlilo, inqubo yobufakazi obuthathu, kanye nenqubo yokuvala amanzi angangeni. Ukusebenza kwenqubo kuhlobene nokukhethwa kwezinto kanye nesilinganiso, ukulawulwa kwepharamitha kanye nekhwalithi yomsebenzisi. Kubakhiqizi abakhulu besikrini se-LED ababonakalayo, ukuqoqwa kokuhlangenwe nakho kubaluleke kakhulu. Imboni enesipiliyoni seminyaka eminingi izosebenza ngempumelelo kakhulu ekulawuleni inqubo yokukhiqiza. .
4. Umthelela wendawo yokusebenza
Ngenxa yokusetshenziswa okwehlukile, izimo zokusebenza zezikrini ezisobala ziyahlukahluka kakhulu. Ngokombono wezemvelo, umehluko wamazinga okushisa asendlini mncane, akukho mvula, iqhwa nokukhanya kwe-ultraviolet; umehluko wezinga lokushisa ongaphandle ungafinyelela kuma-degree angama-70, kanye nomoya nelanga nemvula. Imvelo enokhahlo izokhulisa ukuguga kwesikrini esobala, nokuyinto ebalulekile ethinta impilo yesikrini esobala.
Ukuphila kwesikrini se-LED esibonisa ngale kunqunywa izici ezihlukahlukene, kodwa ukuphela kwempilo okubangelwa izici eziningi kunganwetshwa ngokuqhubekayo ngokushintshwa kwezingxenye (njengokushintsha izinto zamandla). Ama-LED cishe ngeke ashintshwe ngobuningi, ngakho-ke uma impilo ye-LED isiphelile, kusho ukuphela kwempilo yesikrini esibonisa ngale. Ngomqondo othile, impilo ye-LED inquma impilo yesikrini esibonisa ngale.
Sithi ukuphila kwe-LED kunquma isikhathi sempilo yesikrini esibonisa ngale, kodwa akusho ukuthi ukuphila kwe-LED kuyalingana nempilo yonke yesikrini esibonisa ngale. Njengoba isikrini esibonisa ngale singasebenzi ngokugcwala okugcwele ngaso sonke isikhathi uma isikrini esibonisa ngale sisebenza, isikrini esibonisa ngale kufanele sibe nempilo yonke izikhathi ezingu-6-10 zempilo ye-LED uma uhlelo lwevidiyo ludlalwa ngokuvamile. Ukusebenza endaweni ephansi kungahlala isikhathi eside. Ngakho-ke, isikrini esisobala somkhiqizo we-LED singahlala cishe amahora angama-50,000.
Ungasenza kanjani isikrini se- yesikrini se-LED esobala sihlale isikhathi eside?
Kusukela ekuthengeni izinto zokusetshenziswa kuya ekumisweni kokukhiqizwa kanye nenqubo yokufaka, ukusetshenziswa kwezikrini zokubonisa ze-LED kuzoba nomthelela omkhulu. Uhlobo lwezingxenye ze-elekthronikhi ezifana nobuhlalu besibani nama-IC, kuya kwikhwalithi yokushintsha izinto zamandla, zonke izici eziqondile ezithinta impilo yezikrini ezinkulu ze-LED. Lapho sihlela iphrojekthi, kufanele sicacise ikhwalithi yobuhlalu besibani se-LED obuthembekile, idumela elihle lokushintshwa kwamandla kagesi, kanye nohlobo oluthile kanye nemodeli yezinye izinto zokusetshenziswa. Enqubweni yokukhiqiza, kufanele unake izinyathelo eziphikisana ne-static, njengokugqoka izindandatho eziphikisana ne-static, ukugqoka izingubo eziphikisana ne-static, ukukhetha indawo yokusebenzela engenalo uthuli kanye nomugqa wokukhiqiza ukuze unciphise izinga lokuhluleka. Ngaphambi kokushiya imboni, kuyadingeka ukuqinisekisa isikhathi sokuguga ngangokunokwenzeka, futhi izinga lokuphasa kwefektri liyi-100%. Enqubweni yokuthutha, umkhiqizo kufanele upakishwe, futhi ukupakishwa kufanele kube buthakathaka. Uma ithunyelwa, kuyadingeka ukuvimbela hydrochloric acid corrosion
Ngaphezu kwalokho, ukugcinwa kwansuku zonke kwesikrini se-LED esibonakalayo kubaluleke kakhulu, ukuhlanza njalo uthuli oluqoqwe esibukweni, ukuze ungaphazamisi umsebenzi wokukhipha ukushisa. Uma udlala okuqukethwe kokukhangisa, zama ukuthi ungabi mhlophe ngokugcwele, uluhlaza okotshani ngokugcwele, njll., ukuze ugweme ukukhulisa amandla kwamanje, ukushisisa ikhebula nokuhluleka kwesekethe emfushane. Uma udlala iholidi ebusuku, ungakwazi ukulungisa ukukhanya kwesikrini ngokuvumelana nokukhanya kwendawo, okungagcini nje ngokusindisa amandla, kodwa futhi kwandise impilo yesevisi yesibonisi se-LED.
