OLED ndiyo chidimbu cheOrganic Light Emitting Diode,zvinoreva kuti "Organic Light Emitting display technology" muchiChinese.Pfungwa ndeyokuti organic light-emitting layer iri pakati pemaelectrode maviri.Kana maerekitironi akanaka neasina kunaka asangana muorganic material,anoburitsa chiedza.Chimiro chekutanga cheOLED ndeyekugadzira jira re organic light-emitting material makumi e nanometers gobvu pa indium tin oxide (ITO) glass as light-emitting layer.Pamusoro pe light-emitting layer pane layer ye metal electrodes ine low work function, inogadzira chimiro. kunge sandwich.
high tekinoroji OLED kuratidza
Substrate (purasitiki yakajeka, girazi, foil) - Iyo substrate inoshandiswa kutsigira iyo OLED yese.
Anode (TRANSPARENT) - Iyo anode inobvisa maerekitironi (inowedzera erekitironi "maburi") sezvo ikozvino inoyerera nemuchina.
Hole transport layer - Iyi layer inoumbwa ne organic material mamorekuru anotakura "maburi" kubva kune anode.
Luminescent layer - Iyi layer inoumbwa nema organic material molecules (kusiyana ne conductive layer) kunoitwa luminescence process.
Electron transport layer - Iyi layer inoumbwa neorganic material mamorekuru anotakura maerekitironi kubva mucathode.
Macathodes (anogona kuve akajeka kana opaque, zvichienderana nerudzi rweOLED) - Kana ikozvino ichifamba nemumudziyo, ma cathodes anopinza maerekitironi mukati medunhu.
Iyo luminescence process yeOLED kazhinji ine anotevera matanho mashanu ekutanga:
① Jekiseni remutakuri:pasi pekuita kwemunda wemagetsi wekunze, maerekitironi nemakomba anoiswa muiyo organic inoshanda layer yakaiswa pakati pemaelectrodes kubva kucathode uye anode, zvichiteerana.
② Mutakuri wekutakura: maerekitironi akaiswa jekiseni nemakomba anotama kubva kune erekitironi yekutakura layer uye gomba rekutakura dhiza kuenda kune luminescent layer, zvichiteerana.
③ Carrier recombination: mushure mekunge maerekitironi nemakomba abaiwa murunescent layer, anosungwa pamwechete kuti aumbe ma electron hole pairs, kureva, excitons, nekuda kwekuita kwesimba reCoulomb.
④ Exciton migration: Nekuda kwekusaenzana kweelectron uye gomba kutakura, iyo huru exciton yekugadzira dunhu kazhinji haifukidze iyo luminescence layer, saka kupararira kutama kuchaitika nekuda kweiyo concentration gradient.
⑤Exciton radiation inoshatisa mafotoni: An exciton radiative shanduko inoburitsa mafotoni uye inoburitsa simba.
