Usoro ngosi OLED

OLED (Organic Light-Emitting Diode) na-ezo aka na diode ndị na-ewepụta ìhè organic, nke na-anọchite anya ngwaahịa ọhụrụ n'ihe ngosi ekwentị mkpanaaka. N'adịghị ka teknụzụ LCD ọdịnala, teknụzụ ngosipụta OLED anaghị achọ ọkụ azụ. Kama nke ahụ, ọ na-eji mkpuchi ihe organic dị gịrịgịrị na ihe ndị na-agbanwe agbanwe (ma ọ bụ ihe ndị na-agbanwe agbanwe na organic). Mgbe etinyere ọkụ eletrik, ihe ndị a na-emepụta organic na-ewepụta ìhè. Ọzọkwa, enwere ike ime ka ihuenyo OLED dị mfe ma dị gịrịgịrị, na-enye akụkụ ikiri sara mbara, ma belata oriri ike nke ukwuu. A na-akpọkwa OLED teknụzụ ngosipụta ọgbọ nke atọ. Ngosipụta OLED abụghị naanị na ọ dị gịrịgịrị, dị mfe, ma na-arụ ọrụ nke ọma karịa kamakwa ọ na-enwu nke ọma, arụmọrụ ọkụ dị elu, na ikike igosipụta oji dị ọcha. Na mgbakwunye, enwere ike ịgbagọ ha, dịka a na-ahụ na TV na ekwentị mkpanaaka nke oge a. Taa, ndị nrụpụta mba ụwa dị mkpa na-agba ọsọ iji kwalite itinye ego R&D na teknụzụ ngosipụta OLED, na-eduga na ojiji ya na-abawanye ụba na TV, kọmputa (ihe nlele), ekwentị mkpanaaka, mbadamba, na ubi ndị ọzọ. Na Julaị 2022, Apple kwupụtara atụmatụ iwebata ihuenyo OLED na usoro iPad ya n'afọ ndị na-abịa. Ụdị iPad nke afọ 2024 ga-enwe panel ngosi OLED ọhụrụ e mere atụmatụ ya, usoro nke na-eme ka panel ndị a dị gịrịgịrị ma dị mfe karị.

Ụkpụrụ ọrụ nke ihe ngosi OLED dị nnọọ iche na nke LCD. N'ịbụ nke ọkụ eletrik na-akwalite, OLEDs na-enweta mmịpụta ìhè site na ntinye na njikọta nke ihe ndị na-ebu chaja na semiconductor organic na ihe ndị na-enwu enwu. N'ikwu ya n'ụzọ dị mfe, ihuenyo OLED nwere ọtụtụ nde obere "bọọlụ ọkụ".

Ngwaọrụ OLED nwere ihe mejupụtara substrate, anode, oghere injection layer (HIL), oghere transport layer (HTL), electron blocking layer (EBL), emissive layer (EML), oghere blocking layer (HBL), electron transport layer (ETL), electron injection layer (EIL), na cathode. Usoro mmepụta nke teknụzụ ngosi OLED chọrọ nkà teknụzụ dị elu nke ukwuu, nke kewara n'ụzọ sara mbara na usoro azụ. Usoro ihu na-agụnyekarị photolithography na usoro evaporation, ebe usoro azụ na-elekwasị anya na encapsulation na teknụzụ ịkpụ. Ọ bụ ezie na Samsung na LG na-achịkwa teknụzụ OLED dị elu, ọtụtụ ndị na-emepụta ihe na China na-emekwa ka nnyocha ha na ihuenyo OLED dịkwuo elu, na-abawanye itinye ego na ngosipụta OLED. A na-etinyelarị ngwaahịa ngosipụta OLED na onyinye ha. N'agbanyeghị nnukwu oghere ma e jiri ya tụnyere ndị mba ụwa, ngwaahịa ndị a erutela ọkwa a na-eji eme ihe.
