Mid ka mid ah soo jiidashada weyn ee tignoolajiyada ayaa ah inay noo keentay bandhigyada OLED. Haddii aad suuqa ugu jirto bandhig casri ah oo aad rabto in ay yeelato sifooyinka aad filayso, markaa waa inaad xaqiiqdii sahamiso bandhigyada OLED. Xilligan degdegga ah, waxaa habboon in la ogaado faa'iidooyinka bandhigyada OLED.
Waa maxay OLED?
OLED waa soo gaabinta "diode iftiin-bixiya organic". Magac kale waa "diode elektroluminescent organic". Waxay si toos ah u iftiimisaa koronto, si ka duwan habka soo jireenka ah ee iftiiminta iftiinka iyadoo lagu kululeeyo fiilaha korontada. Bandhigyada OLED waxay ka kooban yihiin lakabyo khafiif ah oo quraarado ah, caag ah iyo unugyo dabiici ah oo gaar ah kuwaas oo ka falceliya kharashka korontada oo dhaliya kuleyl aad u hooseeya. Taabashada muraayadda OLED waxay ku dhowdahay inaysan diiranayn, taas oo badbaadisa tamar badan, taas oo ah horumar weyn oo ku saabsan bandhigyadii hore ee CRT ee tamarta-sare.
Taariikhda OLED
Helitaanka tignoolajiyada casriga ah ee OLED waxa dib loo raadin karaa ilaa 1987. Wakhtigaas, laba saynisyahano oo ka kala socday Donman Kodak, Steven Van Slyke iyo Ching Tang, ayaa helay qaar ka mid ah walxaha dabiiciga ah kuwaas oo soo saari kara iftiin yar. Horraantii 1960-kii, helitaanka daahitaanka fluorescence ayaa waddada u xaartay dhalashada OLED. In kasta oo walxaha hore ee organic u baahan yihiin danab sare si ay u iftiimiyaan iftiinka, saynisyahano Kodak ku guulaysteen in ay gaaraan fluorescence at danab hooseeya.
Saynis yahanadaan ayaa markii ugu horeysay soo saaray OLEDs leh jaale-cagaaran spectrum ah, ka dibna spectrum orange-cas, ugu dambeyntiina waxay ka gudbeen sharciga farqiga tamarta si ay si guul leh u gaaraan qiiqa gaduudka cas. Later, sida tignoolajiyadu soo hagaagtay, bandhigyo cusub oo OLED ah sida AMOLED (matrix firfircoon oo iftiin-bixiye organic ah) ayaa soo muuqday.
Qaybaha muhiimka ah ee Muujinta OLED
Wadnaha soo bandhigida OLED waa Emitter OLED. Waa qayb dabiici ah oo ifaysa marka laydhka la isticmaalo. Qaab dhismeedka aasaasiga ah waxaa ka mid ah lakabka walxaha u dhexeeya anode iyo cathode. Aaladaha casriga ah ee OLED waxay leeyihiin lakabyo badan si loo hagaajiyo adkeysiga iyo waxtarka, laakiin shaqada aasaasiga ah ayaa weli ah sidii hore. Dabaqyada OLED waxay ka kooban yihiin guddi hore, guddi danbe, korantada, lakabka daboolka, iyo substrate. Nidaamkani wuxuu aad ugu nugul yahay qoyaanka iyo oksijiinta, sidaas darteed lakabka daboolka ayaa ah mid aad u adag.
Substrate
Saldhigga bandhigyada OLED waa muraayad ama caag, walxo hufan oo siinaya meel deggan oo qaybaha kale.
Lakabyada dabiiciga ah
Lakabyo badan oo walxo organic ah ayaa lagu shubaa substrate, oo ay ku jiraan:
Lakabka soo baxaya: Waxa ku jira molecules organic kuwaas oo ku sii daaya iftiinka hoos yimaada kicinta korantada.
Lakabka gaadiidka daloolka:Ku rarida kharashyo togan (goddaleedyada) lakabka soo baxaya.
Lakabka gaadiidka korantada: Ku rarida khidmadaha taban (electrons) ilaa lakabka soo baxaya.
Lakabka Waxqabadka hufan
Lakabkani waxa uu ku yaalaa labada dhinac ee lakabka organic waxana uu u shaqeeyaa sidii elektrode hufan, taas oo u ogolaanaysa hadda in uu soo galo kana baxo lakabka organic.
Lakabka Encapsulation
Si loo ilaaliyo lakabka dabiiciga ah ee jilicsan ee qoyaanka iyo ogsijiinta, lakabka daboolka ayaa badanaa lagu dabaqaa dusha sare, kaas oo ka kooban walxaha xannibaadda kaas oo ka hortagaya arrimaha deegaanka inay saameeyaan lakabka organic.

Goorma ayaa la dooranayaa Muujinta OLED ee Codsiyada Ganacsiga?
Bandhigyada OLED waxay bixiyaan tayada muuqaal wanaagsan oo loogu talagalay codsiyada ganacsiga halkaasoo muuqaallada cajiibka ah ay mudnaanta siinayaan. Waa kuwan qaar ka mid ah tixgelinnada muhiimka ah:
Waxyaabaha ka kooban xal sare:Bandhigyada OLED waa doorasho aad u fiican marka sawirada, fiidiyowyada, ama garaafyada la rabo in la soo bandhigo heerka sare.
•Xaglo daawasho ballaadhan:Bandhigyada OLED waxay bixiyaan xaglo daawasho joogto ah, iyadoo la hubinayo in nuxurka si sax ah loo soo bandhigay marka laga eego dhinacyo kala duwan.
•Naqshad khafiif ah oo khafiif ah:Bandhigyada OLED waa ka khafiifsan yihiin oo ka fudud yihiin bandhigyada LCD-ga caadiga ah, taas oo ka dhigaysa inay ku habboon yihiin codsiyada meelaha bannaan ee xaddidan ama naqshad jilicsan ayaa loo baahan yahay.
•Isticmaalka koronto yar:Bandhigyada OLED ayaa ka tamar badan ka waxtar badan bandhigyada LCD, yaraynta kharashaadka hawlgalka iyo saamaynta deegaanka.
Haddii codsigaaga ganacsi uu u baahan yahay tayada muuqaal aad u wanaagsan, xaglo daawasho oo ballaadhan, iyo nashqad qurxoon, bandhiga OLED ayaa noqon kara doorashada ugu fiican.
Farqiga u dhexeeya OLED Vs LED/QLED
Bandhigyada LED-ga ee dhaqameedku waxay ku saleysan yihiin tignoolajiyada LCD, qaab-dhismeed waqti la tijaabiyay. Shaashado LCD waxay ka kooban yihiin shabag dhuuban oo transistor ah oo ku shaqeeya isticmaalka walxo yaryar oo crystal ah. Habkani wuxuu ku lug leeyahay nidaaminta pixels mugdiga iyo dhalaalaya, laakiin iftiinka dhabta ah ee iftiiminta wuxuu ka yimaadaa kaydinta LED-yada. Habka ugu fiican ee lagu tijaabiyo shaashadda LCD waa in la isticmaalo iftiinka dambe ee LED, kaas oo u oggolaanaya kala duwanaansho sare iyo hoos u dhac wanaagsan, taas oo ka dhigaysa muuqaal ka fiican noocyadii hore. Tiknoolajiyada OLED waxay sii socotaa tallaabo dheeraad ah, oo bixisa ilaalinta indhaha oo aan keenin daal aragga.
Dhismaha bandhigyada QLED aad ayuu uga duwan yahay bandhigyada OLED. Bandhigyada QLED waxay isticmaalaan dhibco quantum ah, kuwaas oo soo saara iftiin marka la shido, oo la mid ah OLED. Laakiin QLED waxay u beddeshaa iftiinka buluugga ah ee ay hesho iftiin cad, kaas oo lagu gaaro iyadoo la adeegsanayo dhibcaha quantum ee casaanka iyo buluugga ah. Bandhigyada QLED way ka iftiimeen, laakiin sidoo kale way ka qaalisan yihiin OLED waxayna weli ku jiraan marxaladaha hore ee horumarka. Taa bedelkeeda, bandhigyada OLED waa kuwo iskood u iftiimaya, midabkoodana soo bandhiga, waana ka qaalisan yihiin. Bandhigyada LED-ka, dhanka kale, waa guddi ka sameysan daroodhyo iftiin leh, waxaana inta badan loo adeegsadaa boorarka iyo calaamadaha.
