Njengobuchwepheshe obuvelayo bokuboniswa, izikrini ze-LED ezibonisa ngale, nezinzuzo zazo ezifana nokucaca okuphezulu, umklamo ongasindi, nokufakwa okuvumelana nezimo, zisetshenziswa kakhulu ekubonisweni kwezentengiselwano, imidlalo yasesiteji, izindonga zamakhethini ezakhiwo, nezinye izinkambu.Nokho, zibhekene nezinhlobonhlobo zemikhiqizo emakethe, ukukhetha isikrini se-LED esisobala esifanelana nezidingo zabo kuyinselele kubasebenzisi abaningi. Lesi sihloko sizohlaziya izici ezibalulekile ekukhetheni isikrini se-LED esibonisa ngale emibonweni eminingi ukuze sisize abasebenzisi benze isinqumo esinolwazi.
Khomba Isimo Sesicelo kanye Nezimfuneko
Ukukhethwa kwesikrini se-LED esibonisa ngale kufanele kuqala kusekelwe esimweni sangempela sohlelo lokusebenza. Izindawo ezihlukene zokusetshenziswa zinezidingo ezihlukile zokubonisa ngale kwesikrini, ukukhanya, izinga lokuvuselela, namanye amapharamitha. Ngokwesibonelo:
- Izibonisi zezentengiso (ezifana nezibonisi zamawindi nezitolo zomkhiqizo):Ukukhanya okuphezulu (ngaphezulu kuka-80%) nokukhanya okumaphakathi (2000-4000 nits) ngokuvamile kuyadingeka ukuze kuqinisekiswe kokubili ukudluliswa kokukhanya kwangemuva nokucaca kokuqukethwe.
- Amakhonsathi esiteji:Amazinga okuvuselela aphezulu (Amakhulu noma alingana no-1920Hz) nokuqhathanisa kuyadingeka ukuze kuqinisekiswe izithombe eziguquguqukayo ezibushelelezi ngaphandle kwama-artifact, kuyilapho kuqinisekiswa ukumelana kwamanzi nothuli (isilinganiso se-IP).
- Izindonga zamakhethini ezakhiwo:Cabanga ukumelana nesimo sezulu (i-UV nokumelana nokushisa), amandla esakhiwo, nokufaka kalula.
Ngemva kokucacisa ukusetshenziswa okuhlosiwe, usayizi wesikrini, ukulungiswa, nendlela yokufaka (isb., indawo-yokukhweza, usilingi{3}}okugxunyekiwe, noma okushunyekiwe) kunganqunywa ngokuqhubekayo.
Ukuhlaziywa Kwepharamitha Ebalulekile
1. Ukungafihli
Ukungafihli kwesikrini se-LED esibonisa ngale kuthinta ngokuqondile umphumela wokubuka futhi kuvame ukuvezwa njengephesenti. Imikhiqizo ejwayelekile inokukhanyela okuphakathi kuka-50% no-90%, kuyilapho amamodeli aphezulu{3}}angadlula u-90%. Uma udinga ukugcina ukubonakala okukhulu kwangemuva (isb, ekubonisweni kwamafasitela), kufanele ubeke kuqala imikhiqizo ngokukhanyela okuphezulu.
2. Iphikseli Pitch
Ukuphakama kwe-Pixel kubhekisela ebangeni eliphakathi kwama-LED futhi kuthinta ngokuqondile ukulungiswa nokucaca. Ukucaciswa okujwayelekile kufaka phakathi i-P3, i-P5, ne-P8 (inombolo encane, ukuphakama kwephikseli ephezulu). Ukuze-ubuke eduze (isb, izibonisi zekhawunta), i-P3-i-P5 iyanconywa; ukubuka kude (isb, izindonga zamakhethini amakhulu), i-P8 nangaphezulu kuyanconywa.
3. Ukugqama Nokugqama
Ukukhanya kukalwa ngama-nits. Izigcawu zasendlini ngokuvamile zidinga ama-nits angu-2000-4000, kuyilapho izigcawu zangaphandle zidinga ama-nits angu-5000 noma ngaphezulu ukuze zimelane nemisebe yelanga eqondile. Isilinganiso esiphezulu sokungafani sidala isendlalelo sesithombe esicace kakhudlwana. Sincoma ukukhetha umkhiqizo onesilinganiso sokungafani esingu-1000:1 noma ngaphezulu.
4. Vuselela Izinga
Izinga lokuvuselela linquma ukushelela kwezithombe eziguqukayo futhi likalwa nge-Hz. Nakuba izibonisi ezijwayelekile zinenani lokuvuselela elingu-60-120 Hz, izikrini ze-LED ezibonisa ngale zidinga izinga lokuvuselela elingu-1920 Hz noma ngaphezulu ukuze zigweme ukucwayiza nama-artifact. Lokhu kulungele ikakhulukazi ukudlalwa kwevidiyo noma ukunyakaza kwesivinini esikhulu.
Ukucatshangelwa Kwempahla Nobuciko
1. Uhlobo lwesibani se-LED
Izikrini ze-LED ezibonisa ngale ezijwayelekile zisebenzisa ubuchwepheshe be-SMD (i-surface-mount) noma i-COB (i-chip-isikali sephakheji). Izibani ze-SMD ziyizindleko eziphansi kodwa zinikeza ukuvikeleka okuncane. Amalambu e-COB ahlanganiswe kakhulu futhi anikeza ukumelana okungcono kothuli namanzi (IP65 noma ngaphezulu), okuwenza afanelekele izindawo ezinokhahlo.
2. PCB kanye neKhabhinethi Design
Izikrini ze-LED ezibonisa ngale{0}eziphezulu zekhwalithi ephezulu zisebenzisa idizayini ye-PCB engenalutho, iqinisekisa ukunqanyulwa kokushisa okusebenzayo kuyilapho ithuthukisa ukudluliswa kokukhanya. I-aluminium alloy noma i-magnesium alloy inconywa kwikhabhinethi, ukulinganisa ukukhanya nokuqina.
3. Ukusebenza Kokukhipha Ukushisa
Ukusebenza okunwetshiwe kungase kubangele ukuthi isikrini sishise ngokweqile, sinciphise ubude baso bempilo. Beka kuqala imikhiqizo efakwe ukupholisa okusebenzayo (njengabalandeli) noma izindlela zokupholisa ezisebenzayo, futhi unake izixazululo zokupholisa ezihlinzekwa umenzi.
Ibhrendi kanye-Nesevisi Yangemuva Kokuthengisa
1. Iziqu Zomkhiqizi
Khetha umkhiqizi onolwazi olunzulu lwe-LED R&D. Hlola izitifiketi ezifanele (ezifana ne-CE, i-FCC, ne-RoHS) kanye nezifundo eziyimpumelelo. {{2}Imikhiqizo eyaziwayo ngokuvamile ihamba phambili ekulinganisweni kombala nasekulawuleni ukungaguquguquki.
2. Amakhono Okwenza ngokwezifiso
Ezinye izimo zidinga-osayizi abangajwayelekile noma umumo ongajwayelekile (njengezikrini ezigobile noma eziyisilinda), ngakho izinsiza zomenzi eziguquguqukayo zokwenza ngendlela oyifisayo zibalulekile.
3. Ngemuva-Usekelo Lokuthengisa
Izikrini ze-LED ezibonisa ngale zibandakanya ukufakwa nokusetshenziswa okuyinkimbinkimbi. Qinisekisa ukuthi umkhiqizi unikeza-ukufakwa kwesayithi, ukuqeqeshwa, kanye{2}}newaranti yesikhathi eside (okungenani{3}}kunconywa iwaranti yeminyaka emithathu).
Izindleko Zokulinganisa-Ukusebenza Nesabelomali
Intengo yesikrini se-LED esibonisa ngale ithonywa izici ezifana nokuminyana kwephikseli, ukukhanya, kanye nomkhiqizo, ngokuvamile osukela ezinkulungwaneni ezimbalwa kuya kumayuan ayizinkulungwane eziyishumi ngemitha yesikwele ngayinye. Kunconywa ukulinganisa ukusebenza nezindleko ngokusekelwe ezidingweni zangempela:
- Ileveli-Yokungena:Ifanele izibonisi ezimile, khetha imodeli ene-pixel density ye-P8 noma ngaphezulu kanye nokukhanya okumaphakathi (Ngaphansi noma kulingana nama-nits angu-3000).
- Uchwepheshe:Ngokudlala{0}}kokuphindaphinda kokuqukethwe okunamandla, isabelomali esiphezulu siyadingeka ukuze kuqinisekiswe amanani okuvuselela aphezulu nokuzinza.
Ukukhethwa kwesikrini se-LED esibonisa ngale kudinga ukucatshangelwa okuphelele kwesimo sohlelo lokusebenza, ukucaciswa okubalulekile, ikhwalithi yezinto ezibonakalayo, kanye{0}}nesevisi yangemva kokuthengisa. Ngokucacisa izidingo zakho, ukuqhathanisa ukucaciswa kobuchwepheshe, nokuhlola amakhono omkhiqizi, abasebenzisi bangakhetha umkhiqizo obhalansisa ukusebenza kanye nezindleko{2}}ezisebenza kahle. Ukunakekelwa okuvamile ngesikhathi sokufakwa nokusebenzisa (njengokuhlanza ama-LED nokuhlola ukujikeleza) nakho kunganweba ubude besikhathi sesikrini futhi kwandise imbuyiselo ekutshalweni kwezimali.
