Izikrini ze-LED ezingabonakali, njengeminye imikhiqizo ye-elektroniki, zinempilo yonke. Yize impilo yethiyori ye-LED ingamahora ayi-100,000, ingasebenza iminyaka engaphezu kwengu-11 ngokuya ngamahora angama-24 ngosuku, izinsuku ezingama-365 ngonyaka, kepha isimo sangempela nedatha yezinkolelo zimbi kakhulu. Ngokwezibalo, impilo yesikrini se-LED esobala emakethe imvamisa iyiminyaka eyi-4 ~ 8, izikrini ze-LED ezisobala ezingasetshenziswa iminyaka engaphezu kwengu-8 bezizinhle kakhulu. Ngakho-ke, impilo yesikrini se-LED esobala ingamahora ayi-100,000, okutholakala ngokufanele. Esimweni sangempela, kuhle ukusebenzisa amahora angama-50,000.
Izici ezithinta impilo yesikrini se-LED esobala yizici zangaphakathi nezangaphandle. Izici zangaphakathi zibandakanya ukusebenza kwezingxenye zomngcele, ukusebenza kwamadivayisi wokukhanyisa ukukhanya kwe-LED, kanye nemikhiqizo yokukhathala yokukhathala. Imvelo yangaphandle transparent LED screen working environment.
1. Umthelela wezinto ezisemaphethelweni
Ngaphezu kwamadivayisi wokukhanyisa we-LED, izikrini ze-LED ezisobala zisebenzisa nezinye izinto eziningi zokuxhuma, kufaka phakathi amabhodi wesifunda, izindlu zepulasitiki, ukushintsha amandla kagesi, izixhumi, i-chassis, njll., Noma iyiphi inkinga nganoma iyiphi into, kungaholela empilweni yesikrini esobala ukunciphisa. Ngakho-ke, impilo ende kakhulu yokuboniswa okusobala inqunywa yimpilo yengxenye ebucayi efushane kakhulu. Isibonelo, i-LED, ukushintshwa kwamandla, kanye nobukhulu bezinsimbi konke kukhethwe ngokuya ngeminyaka engu-8, futhi ukusebenza kwenqubo yokuvikela ibhodi lesifunda kungasekela umsebenzi wayo iminyaka emithathu kuphela. Ngemuva kweminyaka emi-3, izokonakala ngenxa yokugqwala, lapho-ke singathola kuphela isiqeshana seminyaka emi-3 yesikrini esobala sempilo yonke.
2. Umthelela wokusebenza kwedivayisi yokukhanyisa kwe-LED
Ubuhlalu bezibani ze-LED yizinto ezibucayi kakhulu nezisobala esikrinini esobala. Kobuhlalu bezibani ze-LED, izinkomba ezilandelayo ikakhulukazi: izici zokuncishiswa komoya, izici zokungeniswa kwamanzi okuhwamuka, nokumelana ne-UV. Uma umkhiqizi wesikrini we-LED esobala ehlola ukusebenza kobuhlalu be-LED yesibani, uzosetshenziswa esikrinini esisobala, okuzoholela enanini elikhulu lezingozi zekhwalithi futhi kuthinte kakhulu impilo yesikrini se-LED esobala.
3. Umthelela wokukhathala komkhiqizo
Ukusebenza kokulwa nokukhathala kwemikhiqizo ebonakalayo ye-LED ebonakalayo kuncike kwinqubo yokukhiqiza. Ukusebenza kokulwa nokukhathala kwemodyuli okwenziwe inqubo yokwelashwa engaqinisekisi kathathu kunzima ukukuqinisekisa. Lapho ukushisa nomswakama kuguquka, indawo evikelayo yebhodi lesifunda izonqamphuka, okuholele ekwehleni kokusebenza okuvikelayo.
Ngakho-ke, inqubo yokukhiqiza yesikrini se-LED esobala nayo iyinto esemqoka ekunqumeni impilo yesikrini esobala. Izinqubo zokukhiqiza ezibandakanyeka ekukhiqizweni kwesikrini esobala zifaka phakathi: ukugcinwa kwengxenye kanye nenqubo yokwelashwa kusengaphambili, inqubo yokushisela esithandweni somlilo ngaphezulu, inqubo yobufakazi obuthathu, nenqubo yokuvala amanzi. Ukusebenza kwenqubo kuhlobene nokukhethwa kwezinto ezibonakalayo kanye nokulinganisa, ukulawula ipharamitha kanye nekhwalithi ye-opharetha. Kubakhiqizi abakhulu besikrini se-LED esibonakalayo, ukuqongelela ulwazi kubaluleke kakhulu. Ifektri enesipiliyoni seminyaka eminingi izosebenza kangcono 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.
Impilo yesikrini se-LED esobala inqunywa yizinto ezahlukahlukene, kepha ukuphela kwempilo okubangelwa yizinto eziningi kunganwetshwa ngokuqhubekayo ngokushintshwa kwezakhi (njengokushintsha amandla). Ama-LEDs kungenzeka ukuthi angashintshwa ngobuningi bawo, ngakho-ke uma impilo ye-LED isiphelile, kusho ukuphela kwempilo yesikrini esibonakalayo. Ngomqondo othile, impilo ye-LED inquma impilo yesikrini esobala.
Sithi isikhathi se-LED sinquma isikhathi sokuphila kwesikrini esibonakalayo, kepha akusho ukuthi isikhathi se-LED silingana nesikhathi se-screen esobala. Njengoba isikrini esibonakalayo singasebenzi kumthwalo ogcwele njalo lapho isikrini esibonakalayo sisebenza, isikrini esibonakalayo kufanele sibe nempilo yezikhathi eziyi-6-10 zempilo ye-LED lapho uhlelo lwevidiyo luvame ukudlalwa. Ukusebenza ngamandla aphansi kungahlala isikhathi eside. Ngakho-ke, isikrini esibonakalayo somkhiqizo we-LED singahlala cishe amahora angama-50,000.
Ungasenza kanjani isikrini se-LED esibonakalayo sihlale isikhathi eside?
Kusukela ekuthengeni izinto zokusetshenziswa kuze kube semgomeni wenqubo yokukhiqiza nokufaka, ukusetshenziswa kwezikrini zokubonisa ze-LED kuzoba nomthelela omkhulu. Umkhiqizo wezinto zikagesi ezifana nobuhlalu besibani kanye nama-IC, kukhwalithi yokushintsha amandla kagesi, konke kuyizici eziqondile ezithinta impilo yezikrini ezinkulu ze-LED. Lapho sihlela iphrojekthi, kufanele sicacise ikhwalithi yobuhlalu bezibani ze-LED ezinokwethenjelwa, idumela elihle lokushintsha ukunikezwa kwamandla, kanye nohlobo oluthile nemodeli yezinye izinto zokusetshenziswa. Enkambisweni yokukhiqiza, kufanele unake izinyathelo zokulwa nokuqina, njengokugqoka izindandatho ze-anti-static, ukugqoka izingubo zokulwa, ukukhetha i-workshop engenaluthuli nomugqa wokukhiqiza ukunciphisa izinga lokwehluleka. Ngaphambi kokushiya ifektri, kuyadingeka ukuqinisekisa isikhathi sokuguga ngangokunokwenzeka, futhi izinga lokuphasa lefektri lingu-100%. Enqubeni yokuhamba, umkhiqizo kufanele upakishwe, futhi ukupakisha kufanele kube ntekenteke. Uma kuthunyelwa, kuyadingeka ukuvimbela ukubola kwe-hydrochloric acid.
Ngaphezu kwalokho, ukugcinwa kwansuku zonke kwesikrini se-LED esibonakalayo nakho kubaluleke kakhulu, hlanza njalo uthuli oluqoqwe esikrinini, ukuze lungathinti umsebenzi wokushabalalisa ukushisa. Uma udlala okuqukethwe kokukhangisa, zama ukungabi mhlophe ngokuphelele, uluhlaza ogcwele, njll isikhathi eside, ukuze ugweme ukukhuliswa kwamanje, ukufudumeza ikhebula nokwehluleka kwesifunda okufushane. Lapho udlala iholide ebusuku, ungalungisa ukukhanya kwesikrini ngokuya ngokukhanya kwemvelo, okungagcini nje ngokugcina amandla, kepha futhi okwandisa impilo yensizakalo yesibonisi se-LED.
