Quantum dots siv hauv QLEDs yog semiconductor nanocrystals. Thaum stimulated los ntawm lub teeb los hluav taws xob, cov quantum dots emit xim lub teeb. Cov xim ntawm lub teeb yog txiav txim siab los ntawm kev sib sau thiab qhov loj ntawm cov quantum dots. Yog li ntawd, los ntawm kev hloov cov duab ntawm quantum dots, high-peak ntshiab lub teeb nrog rau lub teeb liab kom xiav lub teeb yuav muab tau.
Quantum dot technology thawj zaug tshwm nyob rau xyoo 1970s. Nws tau pom los ntawm Western lub teb chaws nyob rau hauv kev cia siab ntawm kev nrhiav kev yees duab tshuab hluav taws xob zoo dua thaum lub sijhawm muaj roj teeb. Tam sim no, kev tshawb fawb ntawm quantum dots yog ib qhov chaw nrov heev hauv ntiaj teb. Muaj kaum tawm txhiab tus cov ntaub ntawv luam tawm nyob rau hauv ib xyoos.
"Quantum dots tej zaum yog qhov zoo tshaj plaws cov ntaub ntawv zoo tshaj plaws uas tau pom los ntawm tib neeg." Peng Xiaogang, xib fwb ntawm chemistry ntawm Zhejiang University, hais tias quantum dots yog tov semiconductor nanocrystals. Txhua qhov me me yog ib qho siv lead ua, thiab qhov loj ntawm cov plaub hau me heev. Ib qho ntawm. Tsuas yog yuav tsum tau hloov qhov loj ntawm cov quantum dot, koj tuaj yeem hu mus rau yam xim, thiab xim purity siab, qhov ruaj ntseg ntawm cov siv lead ua los kuj siab, uas nyuaj rau lwm cov ntaub ntawv, thiab tsis tas yuav txhawj xeeb txog kev pab cuam lub neej.
Cov xim gamut yog ib qho qauv uas txiav txim tias ntau npaum li cas xim rau tib neeg qhov muag pom. "Raws li lub siab tshaj plaws BT2020 tus qauv, Kua lub xov tooj txawb tsuas yog li 50%, txhais tau hais tias ib nrab ntawm cov xim tsis tau tso tawm kom pom, tab sis quantum dots yuav ncav cuag 100% xim gamut thiab restore tag nrho cov xim peb yuav perceive," Peng Xiaogang hais.
