Iyintoni i-OLED elinde ubomi?

Njengoko izikrini ze-OLED (Organic Light-Emitting Diode) zisanda kwiindawo eziphathwayo, iiTV, kunye nee-elektroniki ezikumgangatho ophezulu, abathengi kunye nabavelisi ngokufanayo baphakamisa imibuzo malunga nobude bazo. Ezi zikrini ziphilayo nezisebenzisa amandla kakuhle zihlala ixesha elingakanani—kwaye zeziphi izinto ezigqiba ubomi bazo?

Isayensi Ebangela Ukuwohloka kwe-OLED

Itekhnoloji ye-OLED ixhomekeke kwiikhompawundi ze-organic ezikhupha ukukhanya xa umbane udlula kuzo. Ngokungafaniyo nee-LCD zemveli, ezisebenzisa isibane sangasemva, i-pixel nganye kwisibonisi se-OLED ikhanyisa ngokuzimeleyo. Oku kuvumela ubumnyama obunzulu kunye nomahluko ophezulu kodwa kwazisa ubuthathaka obuphambili: izinto ze-organic ziyawohloka ngokuhamba kwexesha.

Abavelisi badla ngokulinganisa ubomi be-OLED ngokwesiqingatha sobomi—ixesha elithathayo ukuba isikrini silahlekelwe yi-50% yokukhanya kwaso kokuqala. Uninzi lweephaneli ze-OLED zanamhlanje, ezifana nezo zikwii-smartphones kunye neeTV zexabiso eliphezulu, zilinganiswa iiyure ezingama-30,000 ukuya kwi-100,000 zokusetyenziswa ngaphambi kokuba zifikelele kwisiqingatha sobomi. Umzekelo:

Iifowuni: Kwiiyure ezi-5-6 zokusetyenziswa kwemihla ngemihla, isikrini se-OLED sinokuhlala iminyaka eli-10-15 ngaphambi kokuba sibonakale sifiphele.

IiTV: Ngokusebenzisa iiyure ezisi-8 zemihla ngemihla, iTV ye-OLED inokugcina ukusebenza kwayo okuphezulu kangangeminyaka esi-8 ukuya kweli-14.

Nangona kunjalo, ubomi obude bokwenyani buxhomekeke kakhulu kwiindlela zokusetyenziswa, iimeko, kunye neemeko zokusingqongileyo.

Izinto Eziphambili Ezichaphazela Ubomi be-OLED:

1. Ukukhanya kwesikrini: Ukukhanya okuphezulu kukhawulezisa ukuguguleka kwee-pixel. Ukusetyenziswa ixesha elide kukukhanya okuphezulu, ngakumbi ngezinto ezingashukumiyo (umz. iilogo okanye iibha zokuhambisa), kunokukhokelela ekutshisweni okanye ekwaluphaleni okungalinganiyo.

2. Ukusetyenziswa kombala: Ii-subpixels eziluhlaza okwesibhakabhaka ziwohloka ngokukhawuleza kunezo zibomvu okanye eziluhlaza, nto leyo enokubangela utshintsho lombala ekuhambeni kwexesha.

3. Ubushushu kunye nokufuma: Ubushushu okanye ukufuma okugqithisileyo kunokukhawulezisa ukuqhekeka kwezinto eziphilayo.

Utshintsho kuShishino ukuze kwandiswe ixesha lokuphila

Abavelisi basebenzise iindlela zokukhusela ukujongana nezi ngxaki. Ii-QD-OLED zeSamsung, iWRGB OLED zeLG, kunye nezikrini zeLTPO zeApple ziquka ubuchwepheshe obufana nobu:

- Ukutshintsha kwePixel: Izinto ezinganyakaziyo ezishukumayo ngokufihlakeleyo ukuthintela ukutsha.

- Iinkqubo zokuTshisa ubushushu: Ukunciphisa uxinzelelo lobushushu kwizinto eziphilayo.

- Ii-Algorithms eziPhambili: Ukulungisa ngokuzenzekelayo ukukhanya kunye nokulinganisela kombala.

 Ngokutsho kwe-DSCC (Display Supply Chain Consultants), iiphaneli ezintsha ze-OLED ezikhutshwe ngo-2023 zibonisa ukuphucuka kwe-15-20% kwixesha lokuphila xa kuthelekiswa neemodeli zika-2020.

Iingcali zicebisa indlela yokwandisa ukuqina kwe-OLED

- Ukusebenzisa useto lokukhanya okuzenzekelayo kunye nokuphepha ukukhanya okuphezulu okuhlala ixesha elide.

- Ukuvumela izigcini zesikrini okanye iindlela zokulala zomxholo ongashukumiyo.

- Ukuhlaziya i-firmware ukuze izuze kuphuculo lomenzi.

Ikamva le-OLED Ubude bexesha elide

Nangona kusekho iingxaki, iindlela zoshishino zibonisa ukuzithemba. I-LG Display isandula ukubhengeza iphaneli entsha ye-OLED enikwe i-150,000 iiyure (iminyaka eli-17 isetyenziswa iiyure ezingama-24 ngosuku, iintsuku ezisi-7 ngosuku), ijolise kwiimpawu zorhwebo. Okwangoku, i-UBI Research iqikelela ukuba ngo-2027, ii-subpixels ze-OLED eziluhlaza okwesibhakabhaka—eyona khonkco ibuthathaka—ziya kubona ubomi obuphindwe kabini ngenxa yokuphumelela kwezinto ze-phosphorescent.

Njengoko uGqr. Jessica Smith, ingcali yezobuchwepheshe bokubonisa eMIT, ephawula: “I-OLED ayigqibelelanga, kodwa ixesha layo lokuphila ngoku lidlula umjikelo wokuphucula oqhelekileyo kwizixhobo ezininzi. Kumsebenzisi oqhelekileyo, ukuveliswa kwescreen kuya kudlula ukuwohloka.”

Njengoko i-OLED isetyenziswa ngakumbi kwiilaptops, ii-automotive displays, kunye nee-foldables, ukuqonda imida yayo—kunye nezisombululo ezitshintshayo—kusabalulekile kubathengi abasebenzisa i-premium displays market.
