Goobta hadda jirta ee tignoolajiyada soo bandhigida, shaashadaha OLED waxay la soo baxaan waxqabadkooda midab leh oo firfircoon oo indho-qabad leh, iyagoo ka helaya raallinimo baahsan soo saarayaasha bandhigyada iyo macaamiisha. Marka, waa maxay sababta bandhigyada OLED ay u soo bandhigi karaan midabada muuqda? Tani waa mid aan ka go'in mabaadi'dooda farsamo ee gaarka ah iyo faa'iidooyinka muhiimka ah.
OLED, ama diode organic-ga iftiimiya, waa tignoolajiyada soo bandhigta halkaas oo walxaha semiconductor-ka organic iyo walxaha iftiimiya ay si iskood ah u iftiimiyaan darawalka hadda socda. Si ka duwan bandhigyada dareeraha dareeraha ah ee dhaqameed (LCDs), OLED uma baahna iftiin dambe, maadaama pixel kasta uu si madax bannaan u iftiimin karo iftiinka. Sifadan is-tustuska leh waa mid ka mid ah qodobbada muhiimka ah ee ka dambeeya midabada firfircoon ee OLED. LCD-yada, iftiinka ka soo baxa nalka dambe wuxuu u baahan yahay inuu dhex maro lakabka dareeraha ah ee crystal iyo filtarrada midabka si ay u soo bandhigaan midabada, habka keena iftiinka qayb ahaan, saameeya nadiifnimada midabka iyo firfircoonaanta.
Taas bedelkeeda, pixels OLED waxay si toos ah u sii daayaan iftiin, iyagoo si wax ku ool ah uga fogaanaya luminta iftiinka iyo samaynta waxqabadka midabka mid saafi ah oo firfircoon. Marka loo eego dhinaca farsamada, tignoolajiyada OLED qaarkood, sida WRGB OLED, waxay qaataan qaab-dhismeed hoose oo afar midab ah, taasoo la macno ah pixel kastaa wuxuu ka kooban yahay afar-pixels: W (cad), R (cas), G (cagaaran), iyo B (buluug). Marka la barbar dhigo piksels saddex-midab ah ee dhaqameed, tignoolajiyadan afarta midab leh waxay wadi kartaa subpixels badan. Qaadashada HD buuxa tusaale ahaan, bandhigyada caadiga ah waxay lahaan karaan kaliya 6.2 milyan subpixels, halka WRGB OLED uu leeyahay ilaa 8.3 milyan subpixels ee matalaadda midabka, taasoo ka dhigaysa midabo qani ah oo faahfaahsan.
Isla mar ahaantaana, WRGB OLED waxay shaqaaleysiisaa tikniyoolajiyada kobcinta midabka, si wax ku ool ah uga fogaato ifafaalaha isbeddelka midabka ee laga yaabo inay ku dhacaan RGB saddexda midab ee OLEDs marka ay soo bandhigayaan midab buluug ah, taas oo soo bandhigaysa 100% midabyo qeexid sare ah oo u dhow dhawaaqyada dabiiciga ah oo si weyn u hagaajinaya firfircoonida midabka iyo saxnaanta. Soosaarayaasha soo bandhigida, faa'iidooyinka tignoolajiyada OLED waxay siinayaan boos wanaagsan tartanka suuqa.
Soosaarayaal badan oo badan ayaa maalgalinaya cilmi baarista, horumarinta, iyo soo saarista bandhigyada OLED, si joogto ah u wanaajiya hababka iyo hagaajinta tayada alaabta. Tusaale ahaan, khadka wax soo saarka ugu horreeya adduunka ee isticmaalaya tignoolajiyada OLED ee daabacan ayaa ka bilowday dhismaha warshad ku taal Wuhan. Tiknoolajiyada OLED ee daabacan waxay bixisaa faa'iidada gamut midabka ballaaran, taasoo sii wanaajineysa waxqabadka midabka ee bandhigyada OLED. Intaa waxaa dheer, tignoolajiyadan, oo la mid ah daabacaadda inkjet-ka, waxay u oggolaaneysaa daabacaadda saxda ah ee alaabta iftiinka, ma aha oo kaliya laba-laabashada waxtarka isticmaalka walxaha, laakiin sidoo kale awood u leh wax soo saarka hoos yimaada shuruudaha deegaanka ee hooseeya, si wax ku ool ah u yareeya isticmaalka tamarta warshadaha. Tani waxay muhiimad weyn u leedahay soosaarayaasha si ay u yareeyaan kharashaadka una hagaajiyaan waxtarka wax soo saarka.
Dhinaca bandhigyada gaarka ah, midabada firfircoon ee OLED waxay sidoo kale muujinayaan soo jiidasho gaar ah. Thanks to waxqabadkooda midabka hodanka ah iyo muuqaalka, bandhigyada OLED waxay buuxin karaan shuruudaha midabka aadka u baahan ee baahiyaha gaarka ah, sida alaabada elektiroonigga ah ee dhamaadka-sare iyo qalabka bandhig xirfadeed. Kala duwanaanshahooda sare iyo sifooyinka gamut midabka ballaaran ayaa awood u siinaya soo bandhigid cad oo muuqaal ah iyo faahfaahinta fiidiyooga, oo leh lakabyo midab kala duwan, oo siinaya isticmaalayaasha khibrad muuqaal leh.
Marka la soo koobo, bandhigyada OLED, oo leh mabda'ooda is-tusaha ah, sifooyin farsamo oo horumarsan, iyo horumarada joogtada ah ee hababka wax soo saarka, waxay noqdeen kuwo isku mid ah midabyo firfircoon. Hadday tahay wax-soo-saarka baaxadda leh ee soo-saareyaasha soo-bandhigista ama baahiyaha gaarka ah ee bandhigyada gaarka ah, OLED waxay soo bandhigaysaa waxqabad aan caadi ahayn iyo karti weyn, si joogto ah u horseedda horumarinta tignoolajiyada bandhigga xagga mustaqbal ifaya oo midab leh.
