Njengobuchwepheshe obusha bokuboniswa, izikrini ze-LED ezibonisa ngale zisanda kuthola ukusetshenziswa okubanzi emibukisweni yezentengiso, izindonga zamakhethini ezakhiwo, imidlalo yasesiteji, neminye imikhakha. Izici zabo eziyinhloko zisemandleni abo okuhlanganisa ukukhanya okuphezulu nekhwalithi yokubonisa enhle kakhulu, okubenza bakwazi ukwethula izithombe eziguqukayo noma ividiyo ngaphandle kokuthinta umbono wangemuva. Izimiso zokuklama zezikrini ze-LED ezibonisa ngale zibandakanya ukulungiselelwa okuhlanganisiwe kwesakhiwo sokubona, ukwakheka kwesekethe, isayensi yezinto ezibonakalayo, nezinhlelo zokulawula. Okulandelayo imininingwane yezindlela zokusebenzisa ubuchwepheshe ngokwemibono eminingi.
Optical Transparency Design Izimiso
Ukukhanyela kwezikrini ze-LED ezibonisa ngale kufinyelelwa ngokuyinhloko ngohlelo lwe-pixel oluyingqayizivele kanye{0}}nezinto zokudlulisa ukukhanya. Izibonisi ze-LED zendabuko zinokuminyana kwamaphikseli aphezulu futhi zimbozwe ngezinto ezi-opaque (njenge-epoxy noma i-silicone), okuholela ekukhanyeni okuphansi kakhulu kukonke. Izikrini ze-LED ezibonisa ngale, ngakolunye uhlangothi, zisebenzisa ukwakheka kwephikseli "okugobile{3}}ngaphandle" noma "okunezikhala{4}}ngaphandle", lapho ama-LED ahlakazwa khona ku-matrix ku-substrate ebonisa ngale. Izikhala phakathi kwama-LED zivumela ukukhanya ukuthi kudlule, ngaleyo ndlela kuthuthukiswe ukudluliswa kokukhanya kukonke.Izinketho ezijwayelekile zokuklama zihlanganisa:
1. Idizayini ye-PCB egobile{1}}: Ibhodi lesekethe eliphrintiwe (PCB) lisebenzisa isakhiwo esingenalutho{2}noma esinegridi ukuze kuncishiswe ukuvinjwa{3}ezindaweni ezingakhanyi.
2. Uhlangothi-Ama-LED akhiphayo: Sebenzisa izinhlangothi-ezikhipha ama-chips e-LED ukuze ukhiqize ukukhanya endaweni ethile, unciphise ukuvinjwa kwangemuva.
3. Izinto Zokuhlanganisa Okungafihli: Ama-Optical-ama-resin ebanga noma ama-substrates engilazi asetshenziswa ukuze kuqhutshekwe nokunciphisa ukumuncwa kokukhanya ezindaweni{2}}okungezona ezikhanyayo.
Ngokulungiselela lezi zakhiwo, izikrini zesimanje ze-LED ezibonisa ngale zingafinyelela amazinga okukhanya angama-70% kuya ku-95%, kuye ngephikseli yephikseli nokukhethwa kwezinto.
I-Crcuit and Driver Architecture
Idizayini yesiyingi yezikrini ze-LED ezibonisa ngale kufanele ibhalansile-isibonisi sokucaca okuphezulu nokusetshenziswa kwamandla okuphansi. I-core circuitry ngokuvamile ihlanganisa:
1. I-Modular Driver Circuit: Sisebenzisa indlela yedrayivu yokuskena esabalalisiwe, isikrini sihlukaniswa ngamamojula e-LED amaningi azimele, ngalinye lifakwe i-chip yalo yomshayeli-yamanje engaguquki ukuze kuqinisekiswe ukugqama okungaguquki nombala.
2. Ubuchwepheshe Bokuskena Komugqa/Ikholomu: Ukuhlanganisa ukuskena komugqa namakheli ekholomu kunciphisa inani lemigqa yokudluliswa kwedatha nobunkimbinkimbi besekethe. Eminye imikhiqizo-ephezulu isebenzisa-imodi ye-LED esebenzayo (AM-i-LED), lapho iphikseli ngayinye ye-LED ifakwe khona iswishi ezimele ezacile-ye-film transistor (TFT), enika amandla ukulawula okumpunga okunembe kakhudlwana.
3.Ukunikezwa kwamandla kagesi-okuncane: Ukuze kuthuthukiswe ukuphepha nokunciphisa izimfuneko zokulahla ukushisa, izikrini ze-LED ezibonisa ngale ngokuvamile zisebenzisa amandla aphansi-angu-voltage DC (afana ne-5V noma i-12V) futhi athuthukise ukusetshenziswa kwamandla ngamamojula okuphatha amandla asebenzayo.
Ngaphezu kwalokho, ukusetshenziswa kobuchwepheshe be-flexible printed circuit (FPC) kunika amandla izikrini ze-LED ezibonisa ngale ukuthi zivumelane nezidingo zokufakwa kwendawo egobile, futhi zandise izimo zohlelo lwazo.
Isayensi Yezinto Zokusebenza Nokuthuthukiswa Kokushabalalisa Ukushisa
Ukukhethwa kwezinto ezibonakalayo kwezikrini ze-LED ezibonisa ngale kuthinta ngokuqondile ukudluliswa kokukhanya kwazo, ukuqina, nokusebenza kwazo kokukhipha ukushisa. Izinto ezibalulekile zifaka:
1.I-substrate ekhanyelayo: Izinto ezisetshenziswa kakhulu zifaka ingilazi enkulu-encane, i-polycarbonate (PC), noma i-polymethyl methacrylate (PMMA), enikezela ngokudluliswa kokukhanya okuphezulu namandla amahle okusebenza.
I-2.LED chip packaging: Ukusebenzisa ubuchwepheshe bokupakisha be-COB (Chip on Board) noma i-GOB (Glue on Board), i-chip ye-LED igxiliswe ngokuqondile ku-substrate, futhi isendlalelo sokunamathisela obala sivikela amalunga e-solder futhi sithuthukise ukumelana nomthelela.
3.Isixazululo Sokukhipha Ukushisa: Ngenxa yokuthi ama-LED akhiqiza ukushisa ngesikhathi sokusebenza, izikrini ze-LED ezibonisa ngale ngokuvamile zisebenzisa amafutha ashisayo, ama-backplates ensimbi, noma amasistimu okupholisa asebenzayo (njengamafeni noma ukupholisa uketshezi) ukuze kuqinisekiswe{1}}ukuzinza kokusebenza kwesikhathi eside.
Isistimu Yokulawula kanye Nokudluliselwa Kwesiginali
Ikhwalithi yesibonisi yezikrini ze-LED ezibonisa ngale incike ohlelweni lokulawula olusebenzayo. Imisebenzi yayo eyinhloko ihlanganisa:
1.Ukucutshungulwa kwevidiyo: Iphrosesa yevidiyo iguqula isignali yokufaka (efana ne-HDMI, i-DP, noma ukusakaza kwenethiwekhi) ibe isignali yedijithali efanele isibonisi se-LED, yenza isikali, ukulungisa umbala, nokuthuthukisa izinga lokuvuselela.
I-2.Ukulawula Okuvumelanayo: Kusetshenziswa izikimu zokulawula ezivumelanisiwe noma ezingavumelaniyo. Ukulawula okuvumelanayo kulungele{2}}izimo-zesikhathi sangempela (ezifana nokusebenza kwesiteji), kuyilapho ukulawula okuvumelanayo (njengezibuyekezo zesilawuli kude nge-Wi-Fi noma i-4G) kulungele kakhulu izinhlelo zokusebenza ezimile noma eziphansi{6}}zokubuyekeza imvamisa.
3.Isilinganiso Sokuvuselela Nendawo Empunga: -Izikrini ze-LED ezibonisa ngale eziphezulu zingafinyelela amazinga okuvuselela angaphezu kuka-3840Hz futhi zisekele amaleveli e-grayscale wamabhithi angu-16 noma ngaphezulu, okuqinisekisa ukucwayiza{4}}kwezithombe eziguqukayo zamahhala nokushintsha kombala wemvelo.
Iziqondiso Zokuthuthukiswa Kwekusasa
Idizayini yezikrini ze-LED ezibonisa ngale iyaqhubeka nokuvela, futhi amathrendi wezobuchwepheshe wesikhathi esizayo angahlanganisa:
1.Ukukhanya okuphezulu okuphezulu: Ngokuthuthukisa ukwakheka kwephikseli, ukukhanya kunganyuswa kudlule ama-95%, kusondele ekubonakaleni kwengilazi evamile.
2.Idizayini eguquguqukayo negobekayo: Kuhlanganisa ubuchwepheshe be-elekthronikhi obuguquguqukayo ukuze kuthuthukiswe izibonisi ze-LED eziguquguqukayo noma ezigoqekayo.
3.Imisebenzi yokuthinta nokuzwa okuhlanganisiwe: Ukushumeka izendlalelo zokuthintwa kwe-capacitive noma izinzwa zemvelo kuzikrini ze-LED ezibonisa ngale kunika amandla izibonisi ezisebenzisanayo.
Kafushane, izimiso zokuklama zezikrini ze-LED ezisobala zihlanganisa i-optics, ubunjiniyela be-elekthronikhi, isayensi yezinto ezibonakalayo, nobuchwepheshe bekhompyutha. Umgomo wabo oyinhloko uwukuthola{1}}ukusebenza kokuboniswa kwekhwalithi ephezulu kuyilapho kugcinwa sobala okuphezulu. Ngokuthuthuka okuqhubekayo kwezobuchwepheshe, izikrini ze-LED ezibonisa ngale zizobonisa inani lazo lesicelo elihlukile emikhakheni eyengeziwe.
