Kedu ihe bụ Ngosipụta OLED?

OLED bụ abbreviation nke Organic Light Emitting Diode,nke pụtara "Organic Light Emitting ngosi technology" na Chinese.Echiche bụ na ihe organic ìhè-emitting oyi akwa na-sandwiched n'etiti abụọ electrodes. Mgbe nti na-adịghị mma electrons izute na organic ihe onwunwe, ha emit. ìhè.The isi Ọdịdị nkeOLED bụ ime ka a oyi akwa nke organic ìhè-emitting ihe iri iri nanometers oké na indium tin oxide (ITO) iko dị ka ìhè-emitting oyi akwa. dị ka Sanwichi.

elu technology OLED ngosi

Mkpụrụ (plastic transperent, iko, foil) - A na-eji mkpụrụ ahụ kwado OLED dum.

Anode (N'ụzọ doro anya) - Anọde na-ekpochapụ electrons (na-abawanye "oghere" electron) ka ugbu a na-agafe na ngwaọrụ.

Oghere mbufe oghere - Nke a bụ oyi akwa nke ihe ndị na-emepụta ihe na-ebufe "oghere" site na anode.

Igwe ọkụ na-egbuke egbuke - Nke a bụ ihe mejupụtara ihe ndị na-emepụta ihe na-emepụta ihe (na-emegide n'ígwé ndị na-eduzi) ebe usoro ìhè na-ewere ọnọdụ.

Igwe na-ebufe eletrọn - Nke a bụ oyi akwa nke ihe ndị na-ebuga eletrọn si na cathode.

Cathodes (nke nwere ike ịbụ transperent ma ọ bụ opaque, dabere na ụdị OLED) - Mgbe ugbu a na-agafe na ngwaọrụ ahụ, ndị cathodes na-agbanye electrons n'ime sekit.

Usoro luminescence nke OLED na-enwekarị usoro ise ndị a:

① Carrier injection: n'okpuru omume nke mpụga electric ubi, electrons na oghere na-injected n'ime organic ọtọ oyi akwa sandwiched n'etiti electrodes si cathode na anode, karị.

② Ụgbọ njem na-ebu: electrons injected na oghere na-esi na akwa ebufe eletrọn na oghere na-ebufe oghere gaa na oyi akwa luminescent, n'otu n'otu.

③ Carrier recombination: mgbe eletrọn na oghere gbanyere n'ime oyi akwa luminescent, a na-ejikọta ha ọnụ iji mepụta ụzọ abụọ electron oghere, ya bụ, excitons, n'ihi ọrụ nke Coulomb Force.

④ Exciton Mbugharị: N'ihi ahaghị nhata nke eletrọn na mbufe oghere, mpaghara a na-emepụta exciton anaghị ekpuchi oyi akwa luminescence niile, yabụ mbugharị mgbasa ga-eme n'ihi gradient ntinye.

⑤Exciton radieshon na-emebi photons: Ntugharị radieshon exciton nke na-ewepụta foton na-ewepụta ike.
