Kwicandelo langoku lobuchwepheshe bokubonisa, izikrini ze-OLED zibonakala ngombala wazo oqaqambileyo nonomtsalane, zithandwa kakhulu ngabavelisi bezikrini kunye nabathengi. Ngoko ke, kutheni izikrini ze-OLED zinokubonisa imibala ecacileyo kangaka? Oku akwahlulwa kwimigaqo yazo yobugcisa eyahlukileyo kunye neenzuzo ezibalulekileyo.
I-OLED, okanye i-organic light-emitting diode, yiteknoloji yokubonisa apho izinto ze-semiconductor ze-organic kunye nezinto ezikhupha ukukhanya zikhupha ukukhanya ngokuzimela phantsi kwe-current drive. Ngokungafaniyo neziboniso ze-liquid crystal zemveli (ii-LCD), i-OLED ayifuni ukukhanya kwangasemva, njengoko i-pixel nganye inokukhupha ukukhanya ngokuzimela. Olu phawu lokuzikhupha lolunye lwezinto eziphambili ezibangela imibala eqaqambileyo ye-OLED. Kwii-LCD, ukukhanya okukhutshwa sisibane sangasemva kufuneka kudlule kumaleko we-liquid crystal kunye nezihluzi zemibala ukuze kuvele imibala, inkqubo ekhokelela ekulahlekelweni kokukhanya okuncinci, okuchaphazela ubumsulwa bombala kunye nokuqaqamba.
Ngokwahlukileyo koko, ii-pixel ze-OLED zikhupha ukukhanya ngokuthe ngqo, ziphepha ukulahleka kokukhanya kwaye zenze ukusebenza kombala kube msulwa kwaye kukhanye ngakumbi. Ngokwembono yobuchwephesha, ezinye iiteknoloji ze-OLED, ezifana ne-WRGB OLED, zisebenzisa isakhiwo se-subpixel enemibala emine, oko kuthetha ukuba i-pixel nganye inee-subpixel ezine: W (mhlophe), R (bomvu), G (luhlaza), kunye no-B (luhlaza okwesibhakabhaka). Xa kuthelekiswa nee-pixels zemveli zemibala emithathu, le teknoloji yemibala emine inokuqhuba ii-subpixels ezininzi. Ukuthatha i-HD epheleleyo njengomzekelo, izikrini eziqhelekileyo zinokuba nee-subpixels ezizigidi ezi-6.2 kuphela, ngelixa i-WRGB OLED inee-subpixels ezifikelela kwizigidi ezi-8.3 zokumelwa kombala, okwenza imibala ibe nomtsalane kwaye ibe neenkcukacha ngakumbi.
Kwangaxeshanye, i-WRGB OLED isebenzisa iteknoloji yokuphucula umbala, ithintela ngempumelelo into yokutshintsha kombala enokwenzeka kwii-OLED zendabuko ze-RGB ezinemibala emithathu xa zibonisa oluhlaza okwesibhakabhaka, ngaloo ndlela iveza imibala ecacileyo eyi-100% esondele kwiithoni zendalo kwaye iphucula kakhulu ukukhanya kombala kunye nokuchaneka. Kubavelisi bezibonisi, iingenelo zobuchwepheshe be-OLED zibanika isikhundla esihle kukhuphiswano lwemarike.
Abavelisi abaninzi batyala imali kuphando, uphuhliso, kunye nemveliso yee-OLED displays, beqhubeka nokwenza ngcono iinkqubo kunye nokuphucula umgangatho wemveliso. Umzekelo, umgca wokuqala wemveliso ehlabathini osebenzisa iteknoloji ye-OLED eprintiweyo uqalile ukwakhiwa kumzi-mveliso eWuhan. Iteknoloji ye-OLED eprintiweyo inika inzuzo ye-wide color gamut, iphucula ngakumbi ukusebenza kombala wee-OLED displays. Ngaphezu koko, le teknoloji, efana nokuprinta i-inkjet, ivumela ukuprintwa ngokuchanekileyo kwezinto ezikhupha ukukhanya, kungekuphela nje ngokuphindwe kabini ukusebenza kakuhle kwezinto kodwa kunye nokuvumela imveliso phantsi kweemfuno eziphantsi zokusingqongileyo, kunciphisa ngokufanelekileyo ukusetyenziswa kwamandla kwifektri. Oku kubaluleke kakhulu kubavelisi ukunciphisa iindleko kunye nokuphucula ukusebenza kakuhle kwemveliso.
Kwicandelo leemiboniso ezenziwe ngokwezifiso, imibala eqaqambileyo ye-OLED ikwabonisa ukutsala okukhethekileyo. Ngenxa yokusebenza kwayo okutyebileyo nokucacileyo kwemibala, ii-OLED ziyakwazi ukuhlangabezana neemfuno zombala ezifunekayo kwiimfuno ezenziwe ngokwezifiso, ezifana neemveliso ze-elektroniki eziphezulu kunye nezixhobo zokubonisa zobungcali. Iimpawu zazo ezibalaseleyo kunye nemibala ebanzi zivumela ukubonakaliswa okucacileyo kweenkcukacha zomfanekiso kunye nevidiyo, kunye neeleya zemibala ezicacileyo ngakumbi, ezibonelela abasebenzisi ngamava okubona anzulu.
Ngamafutshane, izibonisi ze-OLED, ngomgaqo wazo wokuzikhupha, iimpawu zobugcisa eziphambili, kunye nokuqhubela phambili okuqhubekayo kwiinkqubo zemveliso, ziye zafana nemibala eqaqambileyo. Nokuba zezemveliso enkulu ngabavelisi bezibonisi okanye iimfuno ezenzelwe wena zezibonisi ezenziwe ngokwezifiso, i-OLED ibonisa ukusebenza okugqwesileyo kunye nobuchule obukhulu, iqhubeka nokukhokela uphuhliso lwetekhnoloji yezibonisi ukuya kwikamva eliqaqambileyo nelinemibala.
