1. Isingeniso
Iphaneli yokubonisa ye-LED evamile inokuvikela okubuthakathaka kumswakama, amanzi, nothuli, ngokuvamile ehlangabezana nezinkinga ezilandelayo:
Ⅰ. Ezindaweni ezinomswakama, amaqoqo amakhulu amaphikseli afile, izibani eziphukile, nezimo “zesibungu” zivame ukwenzeka;
Ⅱ. Ngesikhathi sokusetshenziswa isikhathi eside, umhwamuko womoya opholile kanye namanzi afafazayo kungaguguleka ubuhlalu besibani se-LED;
Ⅲ. Ukunqwabelana kothuli ngaphakathi kwesikrini kuholela ekunqanyulweni kokushisa okungekuhle kanye nokuguga kwesikrini okusheshayo.
Ngokuboniswa okujwayelekile kwe-LED yasendlini, amaphaneli e-LED ngokuvamile alethwa esimweni esingenaphutha efekthri. Kodwa-ke, ngemva kwesikhathi esithile sokusetshenziswa, izinkinga ezifana nezibani eziphukile nokukhanya komugqa kuvame ukwenzeka, futhi ukushayisana okungahlosiwe kungabangela amaconsi ezibani. Ezingosini zokufaka, izindawo ezingalindelekile noma ezingafaneleki ngezinye izikhathi kungase kuhlangatshezwane nazo, njengamaphutha amakhulu abangelwa ukuhluka kwezinga lokushisa elivela ezindaweni zokupholisa umoya ezivunguza ngokuqondile ebangeni eliseduze, noma umswakama ophezulu obangela ukwanda kwamazinga amaphutha esikrini.
Okwangaphakathiukukhanya okuhle kwe-LEDumphakeli onokuhlolwa okuyingxenye yonyaka, ukubhekana nezindaba ezinjengomswakama, uthuli, ukungqubuzana, namazinga amaphutha, nokuthuthukisa ikhwalithi yomkhiqizo kuyilapho kunciphisa umthwalo wesevisi yangemva kokuthengisa kanye nezindleko kuwukukhathazeka okubalulekile kubahlinzeki bokubonisa be-LED.
Umfanekiso 1. Isimo esibi sokukhanya kwe-short-circuit kanye nekholomu yesibonisi se-LED
2. Isixazululo se-AOB Coating se-RTLED
Ukuze sibhekane ngokuphumelelayo nalezi zinkinga,I-RTLEDyethula isisombululo se-AOB (Advanced Optical Bonding) sokumboza. Izikrini ze-AOB coating technology zihlukanisa amashubhu e-LED ekuthinteni kwamakhemikhali angaphandle, ukuvimbela ukungena komswakama nothuli, kuthuthukisa kakhulu ukusebenza kokuvikela kwethu.Izikrini ze-LED.
Lesi sixazululo sisekelwe kunqubo yamanje yokukhiqiza isibonisi se-LED efakwe ngaphakathi endlini, ehlanganisa ngaphandle komthungo nemigqa yokukhiqiza ekhona ye-SMT (Surface Mount Technology).
Umfanekiso 2. Umdwebo ohleliwe wezinto zokumboza ezingaphezulu (indawo ekhanyayo)
Inqubo ethize imi kanje: ngemuva kokuthi amabhodi e-LED enziwe kusetshenziswa ubuchwepheshe be-SMT futhi asebekhulile amahora angama-72, i-coating isetshenziswa endaweni yebhodi, yakha isendlalelo esivikelayo esifaka izikhonkwane ze-conductive, eziwafaka emswakama kanye nemiphumela yomusi, njengoba kubonisiwe. kuMfanekiso 3.
Ngemikhiqizo evamile yokubonisa i-LED enezinga lokuvikela le-IP40 (IPXX, i-X yokuqala ibonisa ukuvikelwa kothuli, futhi i-X yesibili ibonisa ukuvikelwa kwamanzi), ubuchwepheshe bokugqoka i-AOB buthuthukisa ngempumelelo izinga lokuvikelwa kwendawo ye-LED, inikeza ukuvikelwa kokushayisana, kuvimbela amaconsi ezibani. , futhi yehlisa isilinganiso sephutha lesikrini sisonke (PPM). Lesi sixazululo sihlangabezane nesidingo semakethe, sivuthiwe ekukhiqizweni, futhi asikhuphuli ngokwedlulele izindleko zizonke.
Umfanekiso 3. Umdwebo wohlelo lwenqubo yokumboza indawo
Ukwengeza, inqubo yokuvikela ngemuva kwe-PCB (Ibhodi Lesifunda Eliphrintiwe) igcina indlela yangaphambilini yokuvikela upende enobufakazi obuthathu, ithuthukisa izinga lokuvikela ngemuva kwebhodi lesifunda ngokusebenzisa inqubo yokufafaza. Isendlalelo sokuzivikela sakhiwe endaweni ehlanganisiwe (IC), evimbela ukwehluleka kwezingxenye zesifunda ezihlanganisiwe kumjikelezo wedrayivu.
3. Ukuhlaziywa kwezici ze-AOB
3.1 Izakhiwo Zokuzivikela Ezingokoqobo
Izakhiwo zokuvikela ezingokomzimba ze-AOB zincike embotsheni yokugcwalisa engaphansi, enezici zokubopha ezifana ne-solder paste kodwa iyinto evikelayo. Lokhu kunamathela kokugcwalisa kugoqa yonke indawo engezansi ye-LED, okwandisa amandla okuxhumana phakathi kwe-LED ne-PCB. Ukuhlolwa kwelabhorethri kubonisa ukuthi amandla avamile we-SMT solder side-push yi-1kg, kuyilapho isixazululo se-AOB sifinyelela amandla e-side-push we-4kg, ukuxazulula izinkinga zokushayisana ngesikhathi sokufakwa nokugwema ukuhlukaniswa kwephedi okubangela ukuthi amabhodi wezibani angalungiseki.
3.2 Izakhiwo Zokuvikela Amakhemikhali
Izakhiwo zokuvikela amakhemikhali ze-AOB zifaka ungqimba oluvikelayo lwe-matte olubonisa ngale oluhlanganisa i-LED kusetshenziswa impahla ye-polymer ephezulu esetshenziswa ngobuchwepheshe be-nanocoating. Ukuqina kwalolu ungqimba kungu-5~6H esikalini se-Mohs, kuvimbela ngempumelelo umswakama nothuli, ukuqinisekisa ukuthi ubuhlalu besibani abuthintwa kabi imvelo ngesikhathi sokusetshenziswa.
3.3 Okusha Okutholakele Ngaphansi Kwezakhiwo Ezivikelayo
3.3.1 Ukwenyuka kwe-Engeli yokubuka
I-matte transparent protective layer isebenza njengelensi engaphambili kwe-LED, ikhulisa i-engeli ekhipha ukukhanya yobuhlalu besibani se-LED. Ukuhlola kubonisa ukuthi i-engeli yokukhipha ukukhanya inganyuswa isuka ku-140° iye ku-170°.
3.3.2 Ukuxuba Ukukhanya Okuthuthukisiwe
Amadivayisi abekwe phezulu e-SMD ayimithombo yokukhanya okukhomba, eyimbudumbudu kakhudlwana uma iqhathaniswa nemithombo yokukhanya okungaphezulu. Ukufakwa kwe-AOB kwengeza ungqimba lwengilazi ekhanyelayo kuma-SMD LED, kunciphisa ubumbudumbudu ngokubonakala nokuhlehla, ukunciphisa imiphumela ye-moiré, nokuthuthukisa ukuhlanganisa ukukhanya.
3.3.3 Isikrini Esimnyama Esivumelanayo
Imibala ye-inki yebhodi le-PCB engahambisani njalo ibilokhu iyinkinga ezibukweni ze-SMD. Ubuchwepheshe bokumboza be-AOB bungalawula ukujiya nombala wesendlalelo sokumboza, ixazulule ngempumelelo indaba yemibala kayinki ye-PCB engahambisani ngaphandle kokulahlekelwa ama-engeli okubuka, ibhekane kahle nendaba yokusebenzisa amaqoqo ahlukene amabhodi e-PCB ndawonye, nokuthuthukisa ukusebenza kahle kokuthunyelwa.
3.3.4 Ukwenyuka Ukuqhathanisa
I-Nanocoating ivumela ukulawula okunembayo, okunokwakheka kwezinto ezilawulekayo, okwandisa ubumnyama bombala wesisekelo sesikrini nokuthuthukisa ukugqama.
4. Isiphetho
Ubuchwepheshe bokuhlanganisa i-AOB buhlanganisa izikhonkwane ze-electrical conductive eziveziwe, zivimbele ngempumelelo amaphutha abangelwa umswakama nothuli, kuyilapho zinikeza ukuvikelwa kokushayisana. Ngokuvikelwa kokuhlukaniswa kwe-AOB nanocoating, amazinga amaphutha e-LED angehliswa abe ngaphansi kuka-5PPM, athuthukise kakhulu ukukhiqiza kwesikrini nokuthembeka.
Yakhelwe phezu kwesisekelo sokubonisa se-SMD LED, inqubo ye-AOB izuza njengefa izinzuzo zokulungisa isibani esisodwa kalula se-SMD, kuyilapho ithuthukisa ngokugcwele futhi ithuthukisa imiphumela yokusetshenziswa komsebenzisi nokwethembeka ngokomswakamo, uthuli, izinga lokuvikela, nezinga lokukhanya elifile. Ukuvela kwe-AOB kunikeza ukhetho oluphambili lwezisombululo zokubonisa zasendlini futhi kuyingqopha-mlando ekuthuthukisweni kobuchwepheshe bokubonisa i-LED.
I-RTLED entsha enobufakazi obuthathu endliniisibonisi esincane se-LED– akungeni manzi, kungangenisi uthuli futhi kungangeni - AOB Display.Xhumana nathi manjeukuthola isabelo esisemthethweni.
