I-OLED ithetha ntoni kwaye iseyiphi indawo?
I-OLED, ifom ye-LED ephakamileyo, imele idiode ekhanyayo yokukhanya . Ngokungafani ne-LED, esebenzisa umkhanya wokukhanyisa ukubonelela ukukhanya kwiipekseli, i-OELD incike kwizinto eziphilayo ezenziwe ngamaketanga e-hydrocarbon ukuze zikhanye xa zidibana nombane.
Kukho iingenelo ezininzi kule nkqubo, ngokukodwa ukukwazi ukuba nganye iipikseli zikhanyise ngokwabo, zivelise umlinganiselo wokungafani ophezulu, okuthetha ukuba abamnyama bangabomnyama ngokupheleleyo kwaye abamhlophe baqhakazile.
Esi sizathu esona sizathu sisisiseko sezixhobo ezininzi zisebenzisa izikrini ze-OLED, kubandakanywa ii-smartphones, izixhobo ezinxibekayo ezifana ne-smartwatches, iiTV, iipilisi, i-desktop kunye ne- monitor , kunye neekhamera zedijithali. Phakathi kwezixhobo kunye nabanye ziintlobo ezimbini zeziboniso ze-OLED ezilawulwa ngezindlela ezahlukeneyo, ezibizwa ngokuba yi- active matrix (AMOLED) kunye ne -matrix-matrix (PMOLED).
Indlela OLED isebenza ngayo
Iskrini se-OLED siquka inani lezinto. Ngaphakathi kwesakhiwo, esibizwa ngokuba yi- substrate , yindlela yokufumana i-electron, i-anode ethi "idonsa" i-electrons, kunye nesahlulo esiphakathi (i-layer layer) eyahlula.
Ngaphakathi kwinqanaba elingaphakathi lithenda ezimbini ezongezelelweyo, enye yazo enoxanduva lokuvelisa ukukhanya kunye nelinye ukufumana ukukhanya.
Umbala wokukhanya obonwayo kwi-OLED ubonakaliso luchaphazelekayo ngokubomvu, okuluhlaza, kunye noluhlaza okomnxweme. Xa umbala ube ngumnyama, i-pixel inokucinywa ukuze kuqinisekiswe ukuba akukho ukukhanya okwenzelwe loo pixel.
Le ndlela yokwenza umnyama ihluke kakhulu kuneyasetyenziswa nge-LED. Xa i-pixel emnyama ibekwe kumnyama kumboniso we-LED, i-shutter ye-pixel ivaliwe kodwa ukukhanya kwakhona kusasaza ukukhanya, oku kuthetha ukuba akukaze kuhambe yonke indlela.
I-OLED Pros ne-Cons
Xa kuthelekiswa ne-LED kunye nezinye ubuchwepheshe bokubonisa, i-OLED inika ezi ntlawulo:
- Amandla asebenzayo ukususela emva kwesikrini asivuli amandla. Kwakhona, xa kusetshenziswe abamnyama, loo pixel ayifuni amandla kuwo onke, ukugcina amandla angaphezulu.
- Izinga lokuvuselela likhawuleza kuba iifayile zeepixel zisetyenzisiweyo.
- Ngamacandelo amancinci, umboniso, kunye naso sonke isixhobo, sinokuhlala sisincinci kwaye sinzima.
- Umbala omnyama ubumnyama ngokwenene kuba loo pixels inokuvalwa ngokupheleleyo kwaye akukho ukukhanya okukufutshane okuvela kumva okubonelela ukukhanya okungapheliyo kuloo ndawo. Oku kuvumela ukuba umlinganiselo ophezulu ophezulu (oko kukuthi abamhlophe abamhlophe ngaphezu kwamnyama abamnyama).
- Uncedisa i-angle ebonakalayo ebanzi ngaphandle kokulahleka kombala njenge-LED.
- Ukungabi naluphi na uluhlu olugqithiseleyo luvumela iimbonakaliso ezibukhali nezikhenkcelayo.
Nangona kunjalo, kukho ukuphazamiseka kwiziboniso ze-OLED:
- Ekubeni inxalenye yesibonakaliso i-organic, i-OLED ibonisa ukuchithwa kombala ngexesha, elichaphazela ukukhanya kwesikrini jikelele kunye nokulinganisela kombala. Oku kuqhubeka ngakumbi ngelixesha ukususela kwimpahla efunekayo ekwenzeni i-blues ephazamisayo ngokukhawuleza kunokuba i-reds kunye nemifino.
- Izikrini ze-OLED zindleko zokwenza, ubuncinane ngokuthelekiswa nobuchwepheshe obudala.
- Bobabini i-OLED kunye ne-LED ibonisa amava okutshintshwa kwesikrini xa kukho iipekseli ezithile zisebenzise ixesha elide ixesha elide, kodwa umphumo mkhulu kwi-OLED. Nangona kunjalo, esi siphumo siyinxalenye enqunywe inani lamaphikseli nge intshi .
Ulwazi olungakumbi kwi-OLED
Azikho zonke izikrini ze-OLED ezifanayo; Ezinye izixhobo zisebenzisa uhlobo oluthile lwepaneli ye-OLED kuba banokusetyenziswa okuthe ngqo.
Ngokomzekelo, i-smartphone efuna izinga eliphezulu lokuhlaziywa kweemifanekiso ze-HD kunye nolunye umxholo oshintshayo rhoqo, unokusebenzisa i-AMOLED ukubonisa. Kwakhona, kuba ezi ziboniso zisebenzisa i-transistor yefayili encinci ukutshintsha iipixelli / / ukucima ukubonisa umbala, ziyakwazi nokuba zicacile kwaye ziguquguquke, ezibizwa ngokuba yi- OLED (okanye i-FOLED).
Ngakolunye uhlangothi, i-calculator ngokuqhelekileyo ibonisa ulwazi olufanayo kwesikrini ixesha elide kunefowuni, kwaye ivuselela rhoqo, ingasebenzisa iteknoloji enika amandla kwiindawo ezithile zefilimu kude ihlaziywe, njenge-PMOLED, apho ngamnye umqolo wesibonakaliso ulawulwa endaweni yepikseli nganye.
Ezinye iifowuni ezisetyenzisiweyo ze-OLED zivela kubavelisi ukuba imveliso ye-smartphones kunye ne-smartwatches, njengeS Samsung, i-Google, i-Apple kunye neMveliso ebalulekileyo; iikhamera zedijithali ezifana ne-Sony, iPanasonic, i-Nikon kunye ne-Fujifilm; amaphilisi avela kwiLenovo, HP, Samsung, kunye noDell; ii-laptops ezifana ne-Alienware, i-HP kunye ne-Apple; ihlola i-Oxygen, i-Sony, ne-Dell; kunye neethelevishini ezivela kubakhiqizi abanjengoToshiba, iPanasonic, iBhan & Olufsen, i-Sony kunye no-Loewe. Kwaye ezinye ii-radios zemoto kunye nezibane zisebenzisa i-OLED iteknoloji.
Sisiphi isibonakaliso esenziweyo asiyi kuchazi isigqibo sayo. Ngamanye amagama, awukwazi ukuba isisombululo sesiskrini (4K, HD, njl njl) nje ngokuba uyazi ukuba yi-OLED (okanye i- Super AMOLED , i- LCD , i-LED, i- CRT , njl.).
I-QLED lixesha elifanayo elisebenzisa i-Samsung ukuchaza iphaneli apho ii-LED zidibanisa kunye neendwangu zamachashaza eninzi ukuze ikhefu likhanyise ngemibala eyahlukahlukeneyo. Imela i -diode-dot dot-emitting diode .
