Ndị na-emepụta ngwa OLED zuru ụwa ọnụ na-ebupụta ihe ọhụrụ na ngosipụta
Teknụzụ Organic Light-Emitting Diode (OLED), nke a ghọtara dị ka ihe ngosi ngosipụta flat-panel nke ọgbọ na-esote na-esote CRT, PDP, na LCD, na-aga n'ihu na-agbanwe ụlọ ọrụ eletrọnịkị site na arụmọrụ ya dị elu yana ịdị iche iche. N'iji ihe semiconductor organic na-ebunye ọkụ n'okpuru ebe eletriki, OLED na-enye nhazi steeti siri ike zuru oke. na-ejikọta uru nke CRT's elu iche na LCD'profaịlụ slim, mgbe ị na-ewepụ ihe ndọghachi azụ nke nketa.
Ọdịdị OLED na arụmọrụ
Ngwa OLED nke na-ahụkarị nwere ọtụtụ ọkwa na-arụ ọrụ, gụnyere anode, oghere injection Layer (HIL), oghere njem oyi akwa (HTL), oyi akwa ikuku ikuku (EL), oyi akwa elektrọn (ETL), oyi akwa injection elektrọn (EIL), na cathode. Ndị a n'ígwé na-enginered ka ịmepụta a"steepụ”ike-larịị Ọdịdị (Fig. 1), ikwado ịrụ ọrụ nke ọma recombination nke oghere na electrons n'ime emisive oyi akwa na-emepụta ìhè. Usoro doping dị elu na-ebuli ọkwa ike (Tebụl 1-2), na-eme ka arụmọrụ ngwaọrụ na ogologo ndụ dịkwuo elu.
Ngwa nrụpụta igodo
Mmepụta OLED na-adabere na akụrụngwa pụrụ iche ahaziri maka matriks passive (PM-OLED) na matrix na-arụ ọrụ (AM-OLED). Sistemu dị mkpa gụnyere:
PM-OLED: Ngwa ikuku ikuku na ihe mkpuchi.
AM-OLED: Sistemụ nkwụnye ego: ikpo okwu na-agbapụ, plasma-akwalite kemịkalụ vapor deposition (PECVD), na vacuum thermal evaporation (VTE) maka obere ihe nkiri transistor (TFT).
Ngwaọrụ nhazi: mkpuchi mkpuchi, igwe mkpughe, na akọrọ / mmiri mmiri etchers maka imepụta sekit TFT.
Sistemụ mgbanaka: Igwe ọkụ, pipeline gas, na akụrụngwa na-ekpochapụ laser.
Nnwale & nrụzi: TFT eletriki testers, OLED optical analyzers, na igwe ndozi laser.
Ndị na-emepụta ihe pụrụ iche na South Korea na Japan na-achịkwa ụdọ akụrụngwa OLED zuru ụwa ọnụ, ebe ndị ọsụ ụzọ ụlọ ọrụ na-anya ihe ọhụrụ na ntinye ziri ezi, nhazi, na teknụzụ nnwale. Companieslọ ọrụ ndị na-edu ndú akwalitela ọkwá ha site na ọganiihu n'ichepụta ihe dị elu na njikarịcha mkpụrụ.. Ọ bụdị oke mkpa maka ogwe OLED na-emepụta ọtụtụ ihe ejiri na smartphones, TV, na ngwaọrụ wearable.
