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 light.The basic structure ofOLED ndiko kugadzira chidimbu che organic light-emitting material makumi e nanometers akakora pa indium tin oxide (ITO) girazi sechiedza-emitting layer.Pamusoro pechiedza-emitting layer pane chidimbu chesimbi electrodes ine basa rakaderera rekushanda, richigadzira chimiro chakafanana nesangweji.
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 kusimuka kwekufambisa kuchaitika nekuda kwekusimbisa gradient.
⑤Exciton radiation inoshatisa mafotoni: An exciton radiative shanduko inoburitsa mafotoni uye inoburitsa simba.
