Isbeddelka Bandhigyada OLED

OLED (Diode-ka Iftiinka Dabiiciga ah) waxaa loola jeedaa diode-yada iftiinka dabiiciga ah soo saara, kuwaas oo matalaya badeecad cusub oo ku jirta bandhigyada taleefannada gacanta. Si ka duwan tignoolajiyada LCD-ga dhaqameed, tignoolajiyada bandhigga OLED uma baahna iftiin gadaal ah. Taa beddelkeeda, waxay isticmaashaa dahaadh walxo dabiici ah oo aad u khafiif ah iyo substrate-yada galaaska (ama substrate-yada dabiiciga ah ee dabacsan). Marka koronto la mariyo, agabkan dabiiciga ah ayaa iftiin soo saara. Intaa waxaa dheer, shaashadaha OLED waxaa laga dhigi karaa kuwo fudud oo khafiif ah, waxay bixiyaan xaglo daawasho oo ballaaran, waxayna si weyn u yareeyaan isticmaalka awoodda. OLED waxaa sidoo kale loogu yeeraa tignoolajiyada bandhigga jiilka saddexaad. Shaashadaha OLED ma aha oo kaliya kuwo khafiif ah, fudud, iyo kuwo tamar badan leh laakiin sidoo kale waxay leeyihiin dhalaal sare, hufnaan iftiin oo heer sare ah, iyo awoodda lagu soo bandhigo madow saafi ah. Intaa waxaa dheer, waa la qaloocin karaa, sida lagu arkay TV-yada casriga ah ee shaashadda qaloocan iyo taleefannada casriga ah. Maanta, soosaarayaasha caalamiga ah ee waaweyn ayaa ku tartamaya inay kordhiyaan maalgashiga R&D ee tignoolajiyada bandhigga OLED, taasoo horseedaysa codsigeeda sii kordhaya ee ku baahsan TV-yada, kombiyuutarrada (kormeerayaasha), taleefannada casriga ah, kiniiniyada, iyo meelaha kale. Bishii Luulyo 2022, Apple waxay ku dhawaaqday qorshayaal ay ku soo bandhigayso shaashadaha OLED safka iPad-keeda sannadaha soo socda. Moodooyinka iPad-ka ee soo socda ee 2024 waxay soo bandhigi doonaan muraayadaha bandhigga OLED ee cusub ee la naqshadeeyay, taasoo ka dhigaysa muraayadahan kuwo xitaa khafiif ah oo fudud.

Mabda'a shaqada ee shaashadaha OLED wuxuu si weyn uga duwan yahay LCD-yada. Asal ahaan waxaa ka shaqeeya goob koronto, OLED-yadu waxay gaaraan qiiqa iftiinka iyagoo ku duraya oo dib u mideynaya qalabka korontada ku shaqeeya ee semiconductor-ka dabiiciga ah iyo walxaha iftiinka leh. Si fudud haddii loo dhigo, shaashadda OLED waxay ka kooban tahay malaayiin "nalalka iftiinka" oo yaryar.

Qalabka OLED wuxuu inta badan ka kooban yahay substrate, anode, lakabka duritaanka godka (HIL), lakabka gaadiidka godka (HTL), lakabka xannibaadda elektarooniga (EBL), lakabka emissive (EML), lakabka xannibaadda godka (HBL), lakabka gaadiidka elektarooniga (ETL), lakabka duritaanka elektarooniga (EIL), iyo cathode. Habka wax soo saarka ee tignoolajiyada bandhigga OLED wuxuu u baahan yahay xirfad farsamo oo aad u sarreysa, oo si ballaaran loogu qaybiyo hababka hore iyo kuwa dambe. Habka hore wuxuu inta badan ku lug leeyahay farsamooyinka sawir-qaadista iyo uumiga, halka habka dambe uu diiradda saarayo farsamooyinka daboolidda iyo jarista. In kasta oo tignoolajiyada horumarsan ee OLED ay inta badan ku takhasustay Samsung iyo LG, soosaarayaal badan oo Shiinees ah ayaa sidoo kale xoojinaya cilmi-baaristooda shaashadaha OLED, iyagoo kordhinaya maalgashiga shaashadaha OLED. Badeecadaha bandhigga OLED ayaa horey loogu daray alaabadooda. In kasta oo farqi weyn uu jiro marka la barbar dhigo kuwa waaweyn ee caalamiga ah, badeecadahani waxay gaareen heer la isticmaali karo.
