Ib qho OLED (organic teeb emitting diode) muaj ib qho khoom noj khoom haus emissive, uas thaum nkag mus nrog ib qho hluav taws xob tam sim no, muaj peev xwm tsim tau ib qho xim siab puv npo vaj huam sib luag.
Muaj ntau yam ua OLED superior rau LCD lossis CRT tshuab. Qhov feem ntau pom tseeb yog tias OLED yog li ultra-nyias nws muaj peev xwm txawm muab tso rau hauv yas zaj duab xis! Qhov no ua rau nws sib zog dua li qub dua qub thiab muaj txiaj ntsim zoo rau kev tuav tes, cov laptops thiab phau ntawv sau. Nws txawm qhib qhov rooj rau cov lus qhia yooj yim . OLED tseem muaj zog thiab muaj kev sib ntau dua LCD, tab sis tsis tas yuav rov qab teeb pom kev zoo. Nws consumes txog 20% tsawg zog dua LCD, thiab muaj lub sij hawm teb txhua lub sij hawm sai li CRT qhia. Ntxiv rau daim ntawv teev npe no tau hais tias OLED cov lus qhia tau pom tseeb ntawm ze ntawm txhua lub kaum ntse ntse - tag nrho 170 degrees. Xws li yog qhov tsis txaus, lawv khav theem dua kom pom tseeb thiab ua kom tshiab dua 3 xuab moos sai dua yog tsim nyog rau cov kev siv video txheem!
Ib qho OLED zaub muaj cov ntaub qhwv cov ntaub qhwv cov txheej txheem. Thaum muaj hluav taws xob tam sim no, cov khoom xa tawm electrons hauv cathode txheej txav los ntawm cov khoom organic tawm ntawm qhov zoo txaus anode txheej. Qhov rov qab tshwm sim los ntawm qhov anode's sab, raws li zoo ntawm cov electrons raug kos rau ntawm cathode tawm hauv qhov chaw hauv cov khoom siv hluav taws xob. Cov khoom no zoo rau them rau cov khoom siv mus rau recombine nrog electrons, uas ua rau lub teeb ci electroluminescent. Cov tshuaj lom neeg muaj pes tsawg ntawm cov khoom siv cov organic dictates uas xim ntawm lub teeb tsim.
Eastman Kodak tau tsim technology hauv OLED thaum ntxov 1980s thiab tau txhim kho rau nws txij li thaum, nrog rau lwm lub tuam txhab. Sanyo Electric thiab Eastman Kodak sib koom ua ke rau kev sib koom ua ke, SK display , kom thawj OLEDs muaj muag nyob rau hauv cov koob yees duab digital tseem qhia hauv 2003, EasyShare LS633.
Lwm qhov kev tshwm sim tau tshwm sim hauv Lub Kaum Hli Ntuj xyoo 2004, thaum AUO Technology Center tshaj tawm thawj ob tog sib koom tes hauv OLED. Cov ntaub ntawv no muaj peev xwm ua kom pom ob qho duab rau ntawm ib qho dav hlau, tsiv los yog tseem, siv ob sab pem hauv ntej thiab tom qab ntawm lub vaj huam sib luag. Qhov no yog qhov zoo rau cov kev siv xws li hlua-tes uas muaj sab nraud thiab sab hauv.
Txhua yam khoom siv LCD lossis CRT technology yog ib tus neeg sib tw rau OLED, nrog rau kev sib tw, cov xov tooj ntawm tes, cov koob yees duab yees duab, DVD players, GPS, suab lus, PDAs, phau ntawv xov xwm, saib, thiab TV. Nrog rau kev siv zog tsawg, virtual weightlessness, clarity, ci ci thiab dav saib lub kaum ntse ntse, OLED yog lub cim ntxiv rau cov tshuab.
