Iyini Impilo Elindelekile Ye-OLED?

Njengoba izikrini ze-OLED (Organic Light-Emitting Diode) ziba yonke indawo kuma-smartphone, ama-TV, nezinto zikagesi ezisezingeni eliphezulu, abathengi nabakhiqizi ngokufanayo baphakamisa imibuzo mayelana nokuphila isikhathi eside. Ihlala isikhathi esingakanani ngempela le mibukiso ephilayo, ewonga amandla—futhi yiziphi izici ezinquma ubude bayo besikhathi sokuphila?

Isayensi Ngemuva Kokucekelwa phansi kwe-OLED

Ubuchwepheshe be-OLED buncike ezintweni eziphilayo ezikhipha ukukhanya lapho umsinga kagesi udlula kuwo. Ngokungafani nama-LCD omdabu, asebenzisa i-backlight, i-pixel ngayinye kusibonisi se-OLED izikhanyisa ngokuzimela. Lokhu kuvumela okumnyama okujulile nokugqama okuphakeme kodwa kwethula ubungozi obuyinhloko: izinto eziphilayo ziwohloka ngokuhamba kwesikhathi.

Abakhiqizi ngokuvamile bakala ubude bempilo ye-OLED ngokwengxenye yempilo—isikhathi esisithathayo ukuze isikrini silahlekelwe u-50% wokukhanya kwaso kwasekuqaleni. Amaphaneli amaningi esimanje e-OLED, njengalawo akuma-smartphones aphambili nama-TV, alinganiselwe amahora angu-30,000 kuya kwangu-100,000 okusetshenziswa ngaphambi kokufinyelela uhhafu wempilo. Ngokwesibonelo:

Ama-Smartphones: Ngamahora angu-5–6 okusetshenziswa nsuku zonke, isikrini se-OLED singahlala iminyaka engu-10–15 ngaphambi kokufiphala okuphawulekayo.

Ama-TV: Ngamahora angu-8 okusetshenziswa nsuku zonke, i-OLED TV ingase igcine ukusebenza okuphezulu kakhulu iminyaka engu-8–14.

Nokho, ukuphila okude komhlaba wangempela kuncike kakhulu emaphethini okusetshenziswa, izilungiselelo, nezici zemvelo.

Izinto Ezibalulekile Ezithinta Ukuphila Kwe-OLED:

1. Ukukhanya Kwesikrini: Ukukhanya okuphezulu kusheshisa ukugqokwa kwe-pixel. Ukusetshenziswa isikhathi eside ekukhanyeni okuphezulu, ikakhulukazi ngezinto ezimile (isb, amalogo noma amabha okuzulazula), kungaholela ekushiseni noma ekugugeni okungalingani.

2.Ukusetshenziswa Kombala: Amaphikseli aluhlaza sasibhakabhaka ehla ngokushesha kunawobomvu noma aluhlaza, okungenzeka abangele ukushintsha kombala ngokuhamba kwesikhathi.

3. Ukushisa Nomswakama: Ukushisa okudlulele noma umswakama kungasheshisa ukuwohloka kwezinto eziphilayo.

Ukusungulwa Kwemboni Ukunweba Ubude Besikhathi Sokuphila

Abakhiqizi basebenzise izindlela zokuvikela ukubhekana nalezi zinkinga. I-QD-OLED yakwaSamsung, i-LG's WRGB OLED, kanye nezibonisi ze-Apple's LTPO zifaka ubuchwepheshe obufana nokuthi:

- I-Pixel Shifting: Izinto ezinyakazayo ezihamba kancane ukuvimbela ukusha.

- Amasistimu Wokukhipha Ukushisa: Ukunciphisa ukucindezeleka okushisayo ezintweni eziphilayo.

- Ama-Algorithms Athuthukile: Ukulungisa ngokuzenzakalelayo ukukhanya nokulinganisela kombala.

 Ngokusho kwe-DSCC (Display Supply Chain Consultants), amaphaneli amasha e-OLED akhishwe ngo-2023 abonisa ukuthuthuka okungu-15-20% esikhathini sokuphila uma kuqhathaniswa namamodeli ango-2020.

Ochwepheshe batusa indlela yokukhulisa ukuqina kwe-OLED

- Ukusebenzisa izilungiselelo zokukhanya okuzenzakalelayo nokugwema ukukhanya okukhulu okude.

- Ivumela izilondolozi zesikrini noma izindlela zokulala zokuqukethwe okumile.

- Ukubuyekeza i-firmware ukuze uzuze ekuthuthukisweni komkhiqizi.

Ikusasa Lokuphila Okude kwe-OLED

Nakuba ukukhathazeka kuqhubeka, izitayela zemboni ziphakamisa ukuzethemba. I-LG Display isanda kumemezela iphaneli entsha ye-OLED elinganiselwe amahora angu-150,000 (iminyaka engu-17 ekusetshenzisweni okungu-24/7), eqondise izimpawu zokuthengisa. Ngaleso sikhathi, Ucwaningo lwe-UBI lubikezela ukuthi ngo-2027, ama-subpixels e-OLED aluhlaza okwesibhakabhaka—isixhumanisi esibuthaka kakhulu—azobona ubude bempilo buphindwe kabili ngenxa yempumelelo yezinto ze-phosphorescent.

Njengoba uDkt. Jessica Smith, uchwepheshe wezobuchwepheshe e-MIT, ephawula: “I-OLED ayiphelele, kodwa isikhathi sayo sokuphila manje sedlula umjikelezo ovamile wokuthuthukisa amadivaysi amaningi.

Ngokutholwa kwe-OLED kunwebeka kumalaptop, izibonisi zezimoto, nezinto ezigoqekayo, ukuqonda imikhawulo yayo-nezixazululo eziguqukayo-kusabalulekile kubathengi abazulazula emakethe yokubonisa i-premium.
