Kuyamba kwa mawonekedwe a OLED

Zowonetsera za OLED (Organic Light-Emitting Diode) zimayimira ukadaulo wosinthira, pomwe mwayi wawo waukulu uli pamalo awo odziyimira pawokha, ndikupangitsa kuwongolera kwapamwamba kwa pixel popanda kufunikira kwa module yowunikira kumbuyo. Kapangidwe kameneka kamakhala ndi maubwino odabwitsa monga ma ultra-high kusiyana, ma angles apafupi ndi 180-degree, ndi nthawi yoyankhira ma microsecond, pomwe mawonekedwe awo owonda kwambiri komanso osinthika amawapangitsa kukhala abwino pazida zopindika. Chiwonetsero chodziwika bwino cha OLED chimakhala ndi miyandamiyanda yambiri kuphatikiza magawo, magawo a ma elekitirodi, ndi zigawo zogwirira ntchito, zokhala ndi organic emissive layer yomwe imakwaniritsa ma electroluminescence kudzera pakuphatikizanso ma electron-hole. Kusankhidwa kwa zinthu zosiyanasiyana zama organic kumapangitsa kuti pakhale mitundu yotulutsa kuwala.

Kuchokera pamalingaliro ogwirira ntchito, OLED imawonetsa mabowo ndi ma elekitironi kudzera mu anode ndi cathode, motsatana, ndi zonyamulira izi zomwe zimalumikizananso mu organic emissive wosanjikiza kupanga ma excitons ndikutulutsa ma photon. Kachipangizoka kamene kamatulutsa kuwala kolunjika sikumangopangitsa kuti mawonekedwe aziwoneka mosavuta komanso kuti azitha kusiyanitsa mitundu. Pakadali pano, ukadaulo wasintha kukhala machitidwe akulu akulu awiri: ma OLED ang'onoang'ono ndi ma OLED a polima, okhala ndi njira zolondola za doping zomwe zimapititsa patsogolo luso lowala komanso kuyera kwamitundu.

Pamlingo wogwiritsa ntchito, ukadaulo wowonetsera wa OLED walowa m'magawo osiyanasiyana monga zamagetsi ogula, magalimoto, ndi zida zamankhwala. Mafoni apamwamba komanso ma TV amatsogola pamsika chifukwa cha mawonekedwe awo apamwamba, pomwe zowonetsera zamagalimoto zimakulitsa kusinthika kwawo kuti athe kupanga mapangidwe opindika a dashboard. Zida zamankhwala zimapindula ndi mawonekedwe awo apamwamba. Ndi kuwonekera kwa mitundu yatsopano monga ma OLED owonekera ndi ma OLED otambasulidwa, ukadaulo wowonetsera wa OLED ukukulirakulira m'magawo omwe akubwera monga makina anzeru apanyumba ndi zenizeni zowonjezera, zomwe zikuwonetsa kuthekera kwakukulu kwachitukuko.
