Itandukaniro riri hagati ya OLED na LCD

Mu myaka yashize, hamwe niterambere ryihuse ryikoranabuhanga ryerekana, OLED yerekanwe yagaragaye nkibintu byibanze mu gisekuru gishya cyerekana ikoranabuhanga ryerekana, bikurura ibitekerezo by’amasomo n'inganda. OLED yerekana ikoranabuhanga, rizwi kandi nka tekinoroji ya diode ikora ya tekinoroji, igaragaramo imiterere yihariye ya ecran kandi ifite ibyiza byinshi kurenza tekinoroji ya LCD (yamazi ya kirisiti yerekana). Iragenda ikoreshwa muburyo bwa elegitoroniki.

Imiterere ya ecran ya OLED irashobora kugereranywa neza na "hamburger itanga urumuri." Buri gice cya OLED gisa na sandwich, hamwe nibikoresho bitanga urumuri bikora nk'imboga rwagati. By'umwihariko, imiterere ya OLED yerekana igizwe ahanini na substrate (akenshi ikozwe muri plastiki ibonerana cyangwa icyuma kibonerana), anode, urwego kama (harimo urwego ruyobora hamwe na emissive layer), na cathode. Ubusanzwe imiyoboro ikoresha polymers kama nka polyaniline mu gutwara ibyobo, mugihe ibyuka byorohereza ubwikorezi bwa elegitoronike no gusohora urumuri.

Ukurikije uburyo bwo gutwara, ecran ya OLED irashobora gushyirwa mubikorwa-matrix (AMOLED) na passi-matrix (PMOLED). Active-matrix OLEDs ifite ibikoresho bya tristoriste yoroheje (TFTs), bigabanya neza gukoresha ingufu, mugihe passi-matrix OLEDs itwara neza mubikorwa bimwe na bimwe. Bitandukanye na LCDs, isaba module yinyuma, ecran ya OLED nikintu cyonyine cyohereza ibintu kidakeneye itara ryinyuma. Ibi bituma imiterere yacyo yoroshye kandi izana inyungu nyinshi, zirimo impande nini zo kureba, ibihe byihuta byo gusubiza, uburyo bworoshye bwo gutwara ibinyabiziga, gukora amabara yoroshye, hamwe nubushobozi bwo kugera kumpapuro zoroshye kandi zunamye.

Ukurikije amahame yo gushushanya yo kuba yoroheje, yoroheje, mugufi, na mato, tekinoroji ya OLED irakwiriye cyane cyane kubito bito n'ibiciriritse. Isanzwe ikoreshwa cyane mubacuranga MP3, terefone zigendanwa, hamwe nibikoresho bitandukanye bigendanwa. Nubwo ibicuruzwa bimwe na bimwe bya OLED bikiri muri prototype cyangwa imurikagurisha ryamamaza kandi bikaba bitarashyirwa mubikorwa byuzuye, imiterere yabyo ntagereranywa yamenyekanye cyane muruganda. Mugihe kizaza, nkuko ikoranabuhanga rikomeje gukura, OLED yerekanwe biteganijwe ko izasimbuza ecran gakondo ya LCD mubice byinshi hanyuma igahinduka inzira nyamukuru yerekana igisubizo.
