Izibonisi ze-LED zihlangana ezimpilweni zethu zansuku zonke ngesivinini esingakaze sibonwe, ngeI-SMD (Idivayisi Ekhwezwe Ngaphezulu)ubuchwepheshe bugqama njengenye yezingxenye zabo ezibalulekile. Yaziwa ngezinzuzo zayo eziyingqayizivele,Isibonisi se-SMD LEDbathole ukunakwa okubanzi. Kulesi sihloko,I-RTLEDintandohlola izinhlobo, izinhlelo zokusebenza, izinzuzo, nekusasa lesibonisi se-SMD LED.
1. Yini i-SMD LED Display?
I-SMD, emfushane ye-Surface Mounted Device, ibhekisela kudivayisi ebekwe phezulu. Embonini yokubonisa i-SMD LED, ubuchwepheshe be-SMD encapsulation buhlanganisa ukupakisha ama-chips e-LED, abakaki, umkhondo, nezinye izakhi zibe ubuhlalu be-LED obuncane, obungenamthofu, obufakwe ngokuqondile kumabhodi esekethe aphrintiwe (PCBs) kusetshenziswa umshini wokubeka ozenzakalelayo. Uma kuqhathaniswa nobuchwepheshe bendabuko be-DIP (Dual In-line Package), i-SMD encapsulation inokuhlanganiswa okuphezulu, usayizi omncane, nesisindo esilula.
2. Izimiso zokusebenza ze-SMD LED Display
2.1 Isimiso Sokukhanya
Umgomo we-luminescence wama-LED we-SMD usekelwe kumphumela we-electroluminescence wezinto ze-semiconductor. Lapho i-current idlula ku-semiconductor ehlanganisiwe, ama-electron nezimbobo kuhlangana, kukhulula amandla amaningi ngendlela yokukhanya, ngaleyo ndlela kufezeke ukukhanya. Ama-LED ama-SMD asebenzisa ukukhishwa kokukhanya okubandayo, esikhundleni sokushisa noma okuphuma ekukhishweni, okunikela esikhathini eside sokuphila kwawo, ngokuvamile ngaphezu kwamahora angu-100,000.
2.2 Ubuchwepheshe be-Ecapsulation
Umnyombo we-SMD encapsulation ilele "ekukhuphukeni" kanye "nokuthengisa." Ama-chips e-LED nezinye izingxenye zimbozwe kubuhlalu be-SMD LED ngezinqubo ezinembayo. Lobu buhlalu bese bufakwa buphinde buthengiswe kuma-PCB kusetshenziswa imishini yokubeka ezenzakalelayo kanye nobuchwepheshe bokuphinda bugcwale izinga lokushisa eliphezulu.
2.3 Amamojula e-Pixel kanye Nendlela Yokushayela
Kusibonisi se-SMD LED, iphikseli ngayinye yakhiwe ngobuhlalu obubodwa be-SMD LED. Lobu buhlalu bungaba yi-monochrome (njengobomvu, obuluhlaza, noma obuluhlaza okwesibhakabhaka) noma umbala ombili, noma umbala ogcwele. Ukuze uthole izibonisi ezinombala ogcwele, ubuhlalu be-LED obubomvu, obuluhlaza, nobuluhlaza okwesibhakabhaka buvame ukusetshenziswa njengeyunithi eyisisekelo. Ngokulungisa ukukhanya kombala ngamunye ngesistimu yokulawula, ukuboniswa kwemibala egcwele kuyafinyelelwa. Imojuli yephikseli ngayinye iqukethe ubuhlalu be-LED obuningi, obudayiswa kuma-PCB, okwakha iyunithi eyisisekelo yesikrini sokubonisa.
2.4 Uhlelo Lokulawula
Isistimu yokulawula yesibonisi se-SMD LED inesibopho sokwamukela nokucubungula amasiginali okokufaka, bese ithumela amasiginali acutshunguliwe kuphikseli ngayinye ukulawula ukukhanya nombala wayo. Isistimu yokulawula ngokuvamile ihlanganisa ukwamukela isignali, ukucubungula idatha, ukudluliswa kwesignali, nokuphathwa kwamandla. Ngokusebenzisa amasekhethi okulawula ayinkimbinkimbi nama-algorithms, isistimu ingakwazi ukulawula iphikseli ngayinye, yethule izithombe ezigqamile nokuqukethwe kwevidiyo.

5. Umehluko phakathi kwe-SMD LED Display kanye ne-COB LED Display
5.1 Usayizi Wokuhlanganisa kanye Nokuminyana
I-SMD encapsulation inobukhulu obubonakalayo obukhulu uma kuqhathaniswa nokuphakama kwephikseli, ifanele amamodeli asendlini anokuphakama kwephikseli ngaphezu kuka-1mm namamodeli angaphandle angaphezu kuka-2mm. I-COB encapsulation iqeda i-LED bead casing, ivumela osayizi abancane be-encapsulation kanye nokuminyana kwe-pixel ephakeme, ilungele izinhlelo zokusebenza ezincane ze-pitch pitch, njengemodeli ye-P0.625 ne-P0.78.
5.2 Ukusebenza kwesibonisi
I-SMD encapsulation isebenzisa imithombo yokukhanya yephoyinti, lapho izakhiwo ze-pixel zingase zibonakale eduze, kodwa ukufana kombala kuhle. I-COB encapsulation isebenzisa imithombo yokukhanya okungaphezulu, enikeza ukukhanya okufanayo okwengeziwe, i-engeli yokubuka ebanzi, kanye nembudumbudu encishisiwe, okuyenza ifaneleke ukubukwa kwebanga eliseduze kuzilungiselelo ezifana nezikhungo zokuyala nezitudiyo.
5.3 Ukuvikelwa Nokuqina
I-SMD encapsulation inokuvikela okuphansi kancane uma kuqhathaniswa ne-COB kodwa kulula ukuyigcina, njengoba ubuhlalu be-LED obubodwa bungashintshwa kalula. I-COB encapsulation inikeza uthuli olungcono, umswakama, nokumelana nokushaqeka, futhi izikrini ze-COB ezithuthukisiwe zingafinyelela ubulukhuni bobuso be-4H, zivikele emonakalweni womthelela.
5.4 Izindleko Nokukhiqiza Okuyinkimbinkimbi
Ubuchwepheshe be-SMD buvuthiwe kodwa bubandakanya inqubo yokukhiqiza eyinkimbinkimbi kanye nezindleko eziphakeme. I-COB yenza inqubo yokukhiqiza ibe lula futhi inciphisa izindleko ngokwethiyori, kodwa idinga ukutshalwa kwezimali okubalulekile kokuqala.
6. Ikusasa Lezikrini Zokubonisa ze-SMD LED
Ikusasa lezibonisi ze-SMD LED lizogxila ekwenziweni okusha kwezobuchwepheshe okuqhubekayo ukuze kuthuthukiswe ukusebenza kwesibonisi, okuhlanganisa osayizi abancane be-encapsulation, ukukhanya okuphezulu, ukukhiqizwa kombala ocebile, nama-engeli okubuka abanzi. Njengoba isidingo semakethe sikhula, izikrini zokubonisa ze-SMD LED ngeke zigcine ubukhona obuqinile emikhakheni evamile njengokukhangisa kwezohwebo nezinkundla kodwa futhi zizohlola izinhlelo zokusebenza ezisafufusa njengokuthwebula ifilimu nokukhiqizwa okubonakalayo kwe-xR. Ukubambisana kulo lonke uchungechunge lwezimboni kuzothuthukisa ukuchuma okuphelele, okuzuzisa kokubili amabhizinisi akhuphukayo naphansi. Ngaphezu kwalokho, ukuvikelwa kwemvelo kanye nokuthambekela okukhaliphile kuzoshintsha intuthuko yesikhathi esizayo, kuphushe izibonisi ze-SMD LED ziye ezixazululweni eziluhlaza, ezonga amandla kakhudlwana, nezihlakaniphile.
7. Isiphetho
Kafushane, izikrini ze-SMD LED ziyinketho ekhethwayo yanoma yiluphi uhlobo lomkhiqizo noma uhlelo lokusebenza. Kulula ukusetha, ukunakekela, nokusebenza, futhi kuthathwa njengokufanelekile kunezinketho zendabuko. Uma uneminye imibuzo, zizwe ukhululekile ukuxhumana nathi manjeukuze uthole usizo.
