Ndị na-emepụta ngwaọrụ OLED zuru ụwa ọnụ na-akwalite ihe ọhụrụ na ngosipụta
Teknụzụ Organic Light-Emitting Diode (OLED), nke a maara dị ka ngwọta ngosipụta flat-panel ọgbọ na-esote na-esochi CRT, PDP, na LCD, na-aga n'ihu na-agbanwe ụlọ ọrụ eletrọniki site na arụmọrụ na mgbanwe dị elu ya. Site na iji ihe semiconductor organic nke na-ewepụta ìhè n'okpuru ubi eletrik, OLED na-enye imewe siri ike zuru oke. ijikọta uru nke CRT'ọdịiche dị elu na LCD'profaịlụ dị gịrịgịrị, ebe ọ na-ewepụ ihe ndọghachi azụ ndị a mụrụ.
Nhazi na Ọrụ OLED
Ngwaọrụ OLED nkịtị nwere ọtụtụ akwa ọrụ, gụnyere anode, oyi akwa ntinye oghere (HIL), oyi akwa nnyefe oghere (HTL), oyi akwa emissive organic (EL), oyi akwa nnyefe electron (ETL), oyi akwa ntinye elektrọn (EIL), na cathode. E mepụtara oyi akwa ndị a iji mepụta"steepụ"nhazi ọkwa ike (Foto 1), na-eme ka njikọta nke oghere na elektrọn dị irè n'ime oyi akwa na-ewepụta ọkụ. Usoro doping dị elu na-eme ka ọkwa ike dịkwuo mma (Tebụl 1-2), na-eme ka arụmọrụ ngwaọrụ na ndụ ya ka mma.
Ngwa Mmepụta Isi
Mmepụta OLED dabere na akụrụngwa pụrụ iche nke ahaziri maka teknụzụ passive matrix (PM-OLED) na active matrix (AM-OLED). Sistemụ dị mkpa gụnyere:
PM-OLED: Ngwa eji ekpochapụ ihe na-eme ka ihe dị n'ime mmiri jupụta.
AM-OLED: Sistemụ mwepụ ihe: Ikpo okwu sputtering, nchekwa anwụrụ kemịkalụ emelitere na plasma (PECVD), na ikuku okpomọkụ vacuum (VTE) maka oyi akwa transistor dị gịrịgịrị (TFT).
Ngwaọrụ nhazi ihe osise: Ihe mkpuchi, igwe na-ekpughe ihe, na ihe e ji agba ihe nkụ/mmiri mmiri maka imepụta sekit TFT.
Sistemụ mmịpụta ọkụ: Ngwa mmịpụta ọkụ, ọkpọkọ gas, na ngwa mmịpụta ọkụ laser.
Nnwale na ndozi: Ihe nnwale eletriki TFT, ihe nyocha anya OLED, na igwe ndozi laser.
Ndị nrụpụta pụrụ iche na South Korea na Japan na-achịkwa usoro nnyefe ngwa OLED zuru ụwa ọnụ, ebe obibi nke ndị ọsụ ụzọ ụlọ ọrụ na-akwalite ihe ọhụrụ na teknụzụ nchekwa, nhazi, na nnwale. Ụlọ ọrụ ndị isi emeela ka ọnọdụ ha sikwuo ike site na ọganihu na mmepụta na nhazi mmepụta dị elu.Ọ bụdị oke mkpa maka panel OLED ndị na-emepụta ọtụtụ ihe eji eme ihe na ekwentị mkpanaaka, TV, na ngwaọrụ ndị a na-eyi.
