Iyini I-COB LED Display Ngempela?

Ngenxa yokuphishekela komuntu isibonisi esiholayo sokuchazwa okuphezulu kakhulu, ukuphakama kwephikseli kwezibonisi ze-LED kuhlala kuncipha.

Njengesizukulwane sokuqala sobuchwepheshe bokuboniswa, isibonisi se-SMD esivamile sesivuthwe kakhulungemva kweminyaka engaphezu kweyishumiukuthuthukiswa.

Ngakho-ke, yimuphi umzila wezobuchwepheshe ozogcina ufisa ukuwuthola esikhathini sokuboniswa kwe-micro led?

Ngokuthuthukiswa kobuchwepheshe bokubonisa i-LED, imizila yobuchwepheshe efana ne-COB (Okufushane kokuthi Chip On Board) iyaphuma.

Futhi, imizila ehlukene yokupakisha ingafaniswa nezakhiwo ezihlukene ze-chip.

I-SMD, eyaziwa ngokuthi amadivaysi afakwe phezulu, ibhekisela ekusebenziseni ubuchwepheshe bokukhweza phezulu ukupakisha imikhiqizo ye-LED.

Ingakwazi ukufaka inkomishi yesibani, ubakaki, i-crystal element, nezinye izinto ezichazwe ngokucacile zobuhlalu besibani.

Lapho ukhiqiza iyunithi yokubonisa enezikhala ezihlukene zezikrini zokubonisa ze-LED ezincane, ubuhlalu besibani bushiselwa ebhodini lesifunda ngomshini we-SMT onesivinini esikhulu one-high-temperature reflow welding. 

Ngokucabangela ubunzima bobuchwepheshe ngesikhathi sokuhlanganisa, abakhiqizi bakhetha i-SMD ukuthi ikhiqize isikrini sokubonisa se-LED esinezikhala esincane.

I-SMD iwubuchwepheshe obuyinhloko bezikrini zokubonisa ze-LED ezincane ezinezikhala zamaphikseli ezingaphansi kuka-10mm emakethe.

Ngakolunye uhlangothi, i-COB, emfushane ye-Chip On Board, ubuchwepheshe obusha bokupakisha obuhlanganisa ama-LED chips, kunokuba izibani ze-LED, ngqo ku-PCB.

Ngakho-ke, i-COB-LED izokhululwa kusayizi obonakalayo we-SMD ukuze uthole ukulungiswa okuphezulu okufana no-P0.9375.

Idijithaliizikrini zokubonisa eziholayo ezincane ku-P0.9375mm, P1.25mm, P1.5625 mm kanye ne-P1.875 ziyatholakala nge-COB.

Ngaphezu kwalokho, akunakuphikwa ukuthi i-COB inezakhiwo zomzimba ezingcono.

Amamojula ahlanganiswe ne-COB awagcini nje ngokulula kunalokho nge-SMD kodwa futhi anombono omkhulu.

Uma kuqhathaniswa ne-SMD, isiphi isibonisi esiholwa yi-COB esingakulethela inzuzo njengoba ngezansi:

1; Ukukhipha ukushisa okuhle kakhulu

Enye yezinhloso zalobu buchwepheshe ukubhekana nenkinga yokukhishwa kokushisa kwe-SMD ne-DIP.

Isakhiwo esilula sinikeza izinzuzo ngaphezu kwezinye izinhlobo ezimbili zemisebe yokushisa.

2; Ifanele isibonisi se-LED sephikseli ewumngcingo

Njengoba ama-chips exhunywe ngokuqondile ebhodini le-PCB, amabanga phakathi kweyunithi ngayinye mancane ukuze kwehliswe ukuphakama kwephikseli ukuze kuhlinzekwe amakhasimende izithombe ezicacile.

3; Yenza ukupakishwa kube lula

Njengoba sishilo ngenhla, isakhiwo se-COB LED silula kune-SMD ne-GOB, ngakho-ke inqubo yokupakisha ilula, futhi.

4; Izinga eliphezulu elingangeni manzi

Nge-chip emisha ebhodini lemojula enamathiselwe, ingavikela kahle i-LED kumojula ye-LED emanzini noma kumswakama.

5; I-Anti-collision engcono

Idizayini ekhethekile ye-modular ene-gluing evimbela ukushayisana ekwazi ukuba nomsebenzi wokufakazela ukushaqeka, enikeza ukuvikeleka okuphezulu kakhulu kwama-LED emithelela eyahlukahlukene.

6; Yeqa Ukuvikela uthuli.

Ngokusebenza kokuvala okuphezulu kwezinto ezintsha, iphaneli yesikrini ye-COB LED evela ku-YONWAYTECH LED ayinalo uthuli ngokuphelele futhi icace kahle kakhulu futhi inikeza ukusebenza okuhle kakhulu kokubuka ngezinga eliphezulu lokuvuselela kanye nombala ofanayo.

Isizathu sokuthembeka okuphezulu ukuthi ubuchwepheshe be-COB bungaqeda isixhumanisi sokulawula ohlelweni olulodwa lokukhiqiza isibani.

Ngaphezu kwalokho, iphinde isuse ubuhlalu besibani phezu kwenqubo ye-welding ye-reflow, ukuze izinga lokushisa eliphezulu ngendlela yendabuko lingeke lithinte i-chip ye-LED kanye ne-welding line.

Ukukhipha ukushisa okuhle kakhulu kanye nokumelana ne-oxidation nakho kunomthelela ekuthembekeni okuphezulu.

Ngaphezu kwalokho, i-COB isebenzisa ubuchwepheshe obusezingeni eliphakeme bokunamathela ukuze kuvinjelwe ukwehluleka kwesibonisi se-LED okubangelwa amanzi, umswakama, i-UV, neminye imonakalo.

Isekela ukusebenza kwesimo sezulu sonke futhi isengasebenza emazingeni okushisa aphezulu ku -30 kuya +80 degrees.

Inqubo yokuvikela ebanzi ivimbela ukungqubuzana noma ukuklwebheka.

Izikrini ezincane ze-LED zingahlanzwa nangendwangu emanzi uma zingcolile.

Ngolwazi olungenhla, ungabona ukuthi ubuchwepheshe be-COB buphakeme kunobuchwepheshe be-SMD esikrinini sokubonisa se-LED. 

Futhi uma ufunaIzibonisi ze-Micro LED, ungase ubhekisele kweminye imikhiqizo ye-YONWAYTECH LED DISPLAY.

Sicela uxhumane nethimba le-YONWAYTECH LED DISPLAY ukuze uthole imininingwane eyengeziwe.
