Iyiphi indlela enhle yokuqeda uhlobo lwamehlo lwe-OLED? Faka ukukhanya kokuchema.

Uma ungumhleli wombala noma umhleli wevidiyo, uyazi ukuthi ubunzima bamehlo bungaba bubi nakakhulu nge-OLED kunakwamanye ubuchwepheshe bokubonisa. Kepha uma ungumlindi we-TV okhuthele, kunethuba elihle lokuthi akukaze kwenzeke kuwe. Isizathu salokhu kungenxa yokuthi ubunzima bamehlo budalwa ngumahluko phakathi kwezigcawu ezimnyama nezigcawu ezikhanyayo esikrinini sakho- lokhu kusho ukuthi lapho ubuka okuqukethwe kusikrini se-OLED, abafundi bakho bahlala benwebeka futhi bexinana ukuze babhekane nababili abamnyama nabamhlophe abakhanyayo. Lokhu kubuyela emuva nangaphandle kudala ukucindezeleka okwengeziwe emehlweni ethu kunalokho okwenzekayo lapho ubuka okuqukethwe kwizibonisi zendabuko.

Ukungafani okungapheli kungahle kungabangeli ubunzima bamehlo obungenamkhawulo, kepha kungaba kubi kakhulu kunamaphaneli e-LED. 

Lapho-ke akukho nje amandla okubonisa, kepha futhi nalokho elikubonisayo. Okuqukethwe okuningi okwakukhona kwakungabekelwanga izibonisi ze-OLED, ngakho-ke abamnyama basengathuthukiswa ezimweni lapho izinga elimnyama kokuqukethwe lingaphezu kuka-zero.

Ama-colorists abamba abahloli be-OLED abangochwepheshe basebenzisa ukukhanya kwe-bias futhi. Akukona ngekhwalithi yesithombe yokubonisa kepha kunalokho okwethu ikhono ukubona leyo khwalithi yesithombe - yindlela izibuko zelanga (ezingezona ezikagqozi) ezingathuthukisa ngayo umbono wethu lapho ushayela imoto ngoba ithuthukisa ikhono lethu lokubona izithombe, ezibonakala zicace bha futhi zibukhali ngenxa yokwanda kwenkundla okuvela kubafundi abanciphile.

Njengoba wazi manje, i-OLED akuyona ubuchwepheshe obukhanya kakhulu. Ngakho-ke, izibani zokuchema zenza kanjani ukuthi ama-OLED abonakale ekhanya ngokwengeziwe? Ake sibonise isibonelo. 

Isiphi isikwele esimhlophe esibonakala sikhanya? Lowo one-dim eyenziwe uzungeze ngakwesobunxele noma lowo ongakwesokudla? 

Zombili ziyizinga lokukhanya okufanayo kodwa ubuchopho bethu bubona isikwele ngakwesobunxele njengokukhanya. 

Akekho owaziyo ukuthi ikusasa likuphatheleni, kepha kuphephile ukusho ukuthi amathiyetha ethu asekhaya azophelelwa yisikhathi eminyakeni eyishumi. Uyakhumbula lapho sathi asikwazi ngisho nokubona amaphikseli ku-10p? Khumbula i-1080i? Ngokusobala sonke siyazi ukuthi isithombe singaba ngcono ngoba sihlala senza, njengoba kunjalo nangekhono lethu lokusihlukanisa.

Ukwenza isibonelo, ukulandela eduze okunye ukusesha okudumile okuletha izivakashi kusayithi lethu, "ukugcinwa kwesithombe se-OLED" kanye "ne-OLED shadow banding" akusalele emuva kakhulu. Lokhu ukukhawulelwa kobuchwepheshe obukhona be-OLED obuye bancishiswa ukukhanyisa okufanelekile kokukhetha. Futhi ngaphandle kwaleyo mikhawulo, okuqukethwe okuningi bekungakhangiswanga ngombala wokuboniswa kwe-OLED, futhi lokhu okuqukethwe kuyazuzisa ngokukhanyisa kokukhetha. 

UJoel Silver ovela ku-ISF uthanda ukusho ukuthi wonke umuntu unemibono yokuthi angayisetha kanjani i-TV, kepha kunamazinga achaziwe amukelwa emhlabeni jikelele. Sonke sinelungelo lokuncamelayo nathi. Lapho ngisebenza kukhompyutha yami ngomsebenzi ongabaluleki kangako ngombala, ngisetha ukukhanya kwami ​​kokuchema kuphakeme kakhulu kunamazinga. Ngoba izibani zokuchema zisebenza kusibukeli hhayi ku-TV, kulungile ukuzama ukuthola izilungiselelo zakho zokukhanya okuhle. 

Uma uhlushwa ibala le-OLED, sincome ukwehlisa ukukhanya kwesibonisi sakho ngemuva kokufaka ukukhanya kwe-bias. Kuzwakala njengokuphikisana, kepha ukukhanya okuncane kokukhanyisa kwenza isibonisi sibonakale sikhanya, ngakho-ke awudingi ukusebenzisa i-TV ngezinga eliphakeme kangaka lokukhanya.
