OLED ine chiedza chayo chinoburitsa chiedza chakakwirira, kona yakafara yekuona, mhinduro inokurumidza, kushandiswa kwesimba shoma, uye inogona kugadzirwa zvishandiso zvekuratidza zvinochinjika, inoonekwa seyakatsiva tekinoroji yekristaro yemvura yakakodzera chizvarwa chinotevera chetekinoroji yekuratidzira. Chikamu chikuru chechiratidziro cheOLED ipikisheni imwe neimwe ine kugona kuburitsa chiedza cheOLED. Chimiro chekutanga chechinhu chinoburitsa chiedza cheOLED chinosanganisira anode, cathode, uye yakasungirirwa pakati pechikamu chinoshanda chinoburitsa chiedza, icho chikamu chinoburitsa chiedza. Maererano nebasa rezvinhu zveOLED mumudziyo uye chimiro chemudziyo, zvinogona kusiyaniswa sehole injection layer (HIL), hole transport layer (HTL), light-emitting layer (EML) electron transport layer (ETL), electron injection layer (EIL) nezvimwe zvinhu.
MumaOLED, jira rekuisa maburi nejira rekufambisa maburi zvinoshandiswa kuvandudza kushanda kwemaburi, nepo jira rekuisa maerekitironi nejira rekufambisa maerekitironi zvichishandiswa kusimudzira kushanda kwemaerekitironi. Zvimwe zvezvinhu zvinoburitsa chiedza pachazvo zvine basa rekutakura maburi kana kutakura maerekitironi, zvinowanzonzi main luminescent; jira rekuisa chiedza muhuwandu hushoma hwemadhayi e organic fluorescent kana phosphorescent rinogona kugamuchira kubva kumuviri mukuru wesimba rekufambisa simba, uye nekubata nekutakura uye kuburitsa ruvara rwakasiyana rwechiedza, chinhu chinoburitsa chiedza chakapetwa chinowanzonziwo muviri we luminescent kana doped light-emitting.
2. Nheyo dzekutanga dzeOLED Device Light Emission
Voltage inoiswa pamudziyo weOLED, uye maburi nemaerekitironi zvinopinzwa muOLED layer kubva kuanode necathode yemudziyo, zvichiteerana. Maburi nemaerekitironi ari muzvinhu zvinoburitsa chiedza cheorganic zvinosanganisa uye zvinoburitsa simba, uye simba rinopfuudzwa rinoendesa mamorekuru ezvinhu zvinoburitsa chiedza cheorganic, kuitira kuti afare kuenda kumamiriro emufaro, uye ipapo exciton kubva kumamiriro emufaro kudzokera kumamiriro epasi, simba riri muchimiro chekusunungurwa, uye pakupedzisira rinoona electroluminescence yemudziyo weOLED.
Kazhinji, firimu iri muOLED rinosanganisira firimu remagetsi rinofambisa mhepo uye jira rega rega rezvinhu zvinoburitsa chiedza cheorganic. Parizvino, ma anode ezvishandiso zveOLED zvakawana kugadzirwa kwakawanda anowanzo gadzirwa uchishandisa tekinoroji yekudzivirira simba remagineti. Ma cathodes nema organic luminescent layers anowanzo gadzirwa ne vacuum evaporation.
