Kusiyana pakati pa OLED ndi QLED

Mu ukadaulo wapamwamba kwambiri wamakono wowonetsera, OLED (Organic Light-Emitting Diode) ndi QLED (Quantum Dot Light-Emitting Diode) mosakayikira ndi mfundo ziwiri zazikulu. Ngakhale mayina awo ndi ofanana, amasiyana kwambiri pa mfundo zaukadaulo, magwiridwe antchito, ndi njira zopangira, pafupifupi kuyimira njira ziwiri zosiyana kwambiri zopititsira patsogolo ukadaulo wowonetsera.

Mwachidule, ukadaulo wowonetsera wa OLED umachokera pa mfundo ya organic electroluminescence, pomwe QLED imadalira njira ya electroluminescent kapena photoluminescent ya madontho a inorganic quantum. Popeza zinthu zopanda chilengedwe nthawi zambiri zimakhala ndi kukhazikika kwa kutentha ndi mankhwala, QLED mwachiphunzitso ili ndi ubwino pankhani ya kukhazikika kwa gwero la kuwala komanso moyo wake. Ichi ndichifukwa chake ambiri amaona QLED ngati njira yabwino kwambiri yowonetsera ukadaulo wa m'badwo wotsatira.

Mwachidule, OLED imatulutsa kuwala kudzera mu zinthu zachilengedwe, pomwe QLED imatulutsa kuwala kudzera mu madontho a inorganic quantum. Ngati LED (Light-Emitting Diode) ikuyerekezeredwa ndi "mayi," ndiye kuti Q ndi O zikuyimira njira ziwiri zosiyana zaukadaulo wa "abambo". LED yokha, monga chipangizo chotulutsa kuwala cha semiconductor, imasangalatsa mphamvu ya kuwala pamene mphamvu yamagetsi imadutsa mu zinthu zowala, zomwe zimapangitsa kuti kuwala kusinthe kukhala kuwala kwa photoelectric.

Ngakhale kuti OLED ndi QLED zonse zimachokera ku mfundo yofunikira yotulutsa kuwala ya LED, zimaposa kwambiri ma LED achikhalidwe pankhani ya mphamvu yowala, kuchuluka kwa ma pixel, magwiridwe antchito amitundu, komanso kuwongolera mphamvu. Ma LED wamba amadalira ma electroluminescent semiconductor chips, omwe ali ndi njira yosavuta yopangira. Ngakhale ma LED ang'onoang'ono omwe ali ndi kuchuluka kwakukulu pakadali pano amatha kufikira pixel pitch yocheperako ya 0.7 mm. Mosiyana ndi zimenezi, OLED ndi QLED zonse zimafuna kafukufuku wapamwamba kwambiri wasayansi ndi miyezo kuyambira pa zipangizo mpaka kupanga zida. Pakadali pano, mayiko ochepa okha monga Germany, Japan, ndi South Korea ali ndi kuthekera kogwiritsa ntchito njira zawo zoperekera zinthu, zomwe zimapangitsa kuti pakhale zopinga zazikulu kwambiri paukadaulo.

Njira yopangira ndi kusiyana kwina kwakukulu. Pakatikati pa OLED yomwe imatulutsa kuwala ndi mamolekyu achilengedwe, omwe pakadali pano amagwiritsa ntchito njira yotulutsira nthunzi—kukonza zinthu zachilengedwe kukhala mamolekyu ang'onoang'ono pansi pa kutentha kwambiri kenako nkuziyikanso pamalo enaake. Njirayi imafuna malo okhala ndi chilengedwe chambiri, imaphatikizapo njira zovuta komanso zida zolondola, ndipo chofunika kwambiri, ikukumana ndi zovuta zazikulu pakukwaniritsa zosowa zopangira zowonetsera zazikulu.

Kumbali ina, malo otulutsira kuwala a QLED ndi ma nanocrystals a semiconductor, omwe amatha kusungunuka m'njira zosiyanasiyana. Izi zimathandiza kukonzekera pogwiritsa ntchito njira zothetsera mavuto, monga ukadaulo wosindikiza. Kumbali imodzi, izi zitha kuchepetsa bwino ndalama zopangira, ndipo kumbali ina, zimadutsa malire a kukula kwa sikirini, ndikukulitsa zochitika zogwiritsira ntchito.

Mwachidule, OLED ndi QLED zikuyimira ukadaulo wapamwamba kwambiri wa ukadaulo wotulutsa kuwala kwachilengedwe ndi kosapangidwa, uliwonse uli ndi mphamvu ndi zofooka zake. OLED imadziwika ndi chiŵerengero chake chapamwamba kwambiri cha kusiyana ndi mawonekedwe ake osinthika, pomwe QLED imakondedwa chifukwa cha kukhazikika kwake pazinthu komanso kuthekera kwake kogula. Ogwiritsa ntchito ayenera kusankha kutengera zosowa zawo zenizeni.
