Mokhoa oa Lipontšo tsa OLED

OLED (Organic Light-Emitting Diode) e bolela di-diode tse ntšang khanya tsa tlhaho, tse emelang sehlahisoa se secha lefapheng la lipontšo tsa mohala oa thekeng. Ho fapana le theknoloji ea setso ea LCD, theknoloji ea ponts'o ea OLED ha e hloke leseli la morao. Ho e-na le hoo, e sebelisa liaparo tse tšesaane haholo tsa lintho tse phelang le li-substrate tsa khalase (kapa li-substrate tse tenyetsehang tsa tlhaho). Ha motlakase o sebelisoa, lisebelisoa tsena tsa tlhaho li ntša leseli. Ho feta moo, li-skrini tsa OLED li ka etsoa hore li be bobebe le ho ba tšesaane, li fane ka li-angle tse pharaletseng tsa ho shebella, 'me li fokotsa tšebeliso ea matla haholo. OLED e boetse e thoholetsoa e le theknoloji ea ponts'o ea moloko oa boraro. Lipontšo tsa OLED ha li tšesaane feela, li bobebe, 'me li boloka matla haholoanyane empa hape li na le khanya e phahameng, bokhoni bo phahameng ba khanya, le bokhoni ba ho bonts'a botšo bo hloekileng. Ho feta moo, li ka kobeha, joalo ka ha ho bonoa lithelevisheneng tsa sejoale-joale tse kobehileng le li-smartphone. Kajeno, bahlahisi ba ka sehloohong ba machaba ba matha ho eketsa matsete a R&D theknolojing ea ponts'o ea OLED, e leng se lebisang ts'ebelisong ea eona e ntseng e ata lithelevisheneng, lik'homphieutha (li-monitor), li-smartphone, matlapa le masimo a mang. Ka Phupu 2022, Apple e phatlalalitse merero ea ho hlahisa li-skrini tsa OLED lenaneng la eona la iPad lilemong tse tlang. Mefuta e tlang ea iPad ea 2024 e tla ba le liphanele tsa ponts'o tsa OLED tse entsoeng bocha, e leng ts'ebetso e etsang hore liphanele tsena li be tšesaane le ho feta.

Molao-motheo o sebetsang oa lipontšo tsa OLED o fapane ka ho feletseng le oa li-LCD. Haholo-holo li tsamaisoa ke tšimo ea motlakase, li-OLED li fumana tlhahiso ea leseli ka ho enta le ho kopanya lijari tsa chaja ka har'a lisebelisoa tsa semiconductor tsa organic le tsa luminescent. Ha re bua ka bonolo, skrine ea OLED e entsoe ka limilione tsa "mabone" a manyane.

Sesebelisoa sa OLED se na le substrate, anode, lera la ho kenya lesoba (HIL), lera la ho tsamaisa lesoba (HTL), lera la ho thibela lielektrone (EBL), lera la ho ntša metsi (EML), lera la ho thibela lesoba (HBL), lera la ho tsamaisa lielektrone (ETL), lera la ho kenya lielektrone (EIL), le cathode. Ts'ebetso ea tlhahiso ea theknoloji ea ponts'o ea OLED e hloka boiphihlelo bo phahameng haholo ba tekheniki, bo arotsoeng ka bophara ka lits'ebetso tsa front-end le back-end. Ts'ebetso ea front-end e kenyelletsa haholo-holo mekhoa ea photolithography le mouoane, ha ts'ebetso ea back-end e shebane le theknoloji ea encapsulation le ho seha. Le hoja theknoloji e tsoetseng pele ea OLED e sebelisoa haholo ke Samsung le LG, bahlahisi ba bangata ba Chaena le bona ba ntse ba matlafatsa lipatlisiso tsa bona ka li-skrini tsa OLED, ba eketsa matsete lipontšong tsa OLED. Lihlahisoa tsa ponts'o ea OLED li se li kenyelelitsoe linyehelong tsa bona. Ho sa tsotellehe lekhalo le leholo ha le bapisoa le linatla tsa machaba, lihlahisoa tsena li fihlile boemong bo ka sebelisoang.
