Hauv tsab ntawv blog no, peb yuav tham txog cov hauv paus ntawm quantum dot zaj duab xis thiab yuav ua li cas nws tsim. Nyob twj ywm rau cov ntawv tshaj tawm yav tom ntej uas yuav nkag mus rau hauv kev nthuav dav ntxiv txog cov txiaj ntsig ntawm kev siv quantum dot zaj duab xis hauv cov duab!

Quantum dot tswvyim thiab lub hauv paus ntsiab lus

Quantum dots: quantum ua yog qhov tseeb nanoscale semiconductor, los ntawm kev siv qee qhov hluav taws xob los yog lub teeb siab rau cov khoom siv nano semiconductor, lawv yuav tawm ib lub teeb ntau zaus, thiab qhov zaus ntawm lub teeb tawm yuav hloov nrog qhov loj ntawm qhov semiconductor. , yog li los ntawm kev kho qhov loj ntawm no nano semiconductor tuaj yeem tswj cov xim ntawm lub teeb ci, vim tias qhov no nano semiconductor muaj cov cuab yeej ntawm kev txwv cov electrons thiab electron qhov, cov cuab yeej no zoo ib yam li cov atoms lossis molecules hauv qhov, thiab yog li ntawd hu ua quantum. dots.

Qhov me me ntawm quantum dots yog, qhov luv luv lub wavelengths tuaj yeem tsim tau, thiab qhov loj dua qhov quantum dots yog, qhov ntev lub wavelengths yuav generated; los ntawm kev sib pauv lub wavelengths ntawm lub teeb emitted los ntawm xiav LEDs, qhov xav tau wavelengths ntawm lub teeb yuav tau txais; los ntawm absorbing luv wavelengths ntawm lub teeb, ib tug neeg quantum dots radiate ib tug nqaim spectrum ntawm lub teeb ntawm kuj ntev wavelengths; los ntawm kev npaj thiab sib sau ua ke quantum dots ntawm tib qhov loj, luminous paj yeeb nrog cov xim purity siab thiab ntse spectra tuaj yeem tau txais, thiab xim reproducibility tuaj yeem ua tiav thiab txhim kho, thiab kev siv hluav taws xob txo.

Quantum Dot Film yog dab tsi?

Quantum dot zaj duab xis: Cov quantum dots yog dispersed ntawm resin khoom, dispersed thiab membranized, thiab encapsulated nrog 2 nplooj ntawv ntawm dej vapor siab barrier zaj duab xis los tsim ib tug sandwich-zoo li multilayer composite qauv.

Raws li qhov loj me me ntawm quantum dots nyob nruab nrab ntawm 1 thiab 10 nm, thaj chaw tshwj xeeb yog qhov loj heev, ua rau cov pa oxygen thiab dej vapor yooj yim puas rau saum npoo ntawm quantum dots, uas ua rau muaj fluorescence tawg. Ntawd yog quantum dot thev naus laus zis tam sim no ntsib cov ntsiab lus: tiv thaiv tshav kub, tiv thaiv oxidation, tsis muaj dej. Yog li ntawd, nws yog ib qho tsim nyog yuav tsum siv ob txheej ntawm cov yeeb yaj kiab siab thiab cov ntaub ntawv tshwj xeeb polymeric qhwv hauv quantum dots los daws cov teeb meem no.

Kev tiv thaiv tshav kub tiv thaiv: Txais yuav daim ntawv zaj duab xis thiab teeb tsa qhov kev ncua deb ntawm LED teeb qhov chaw ntawm qhov chaw tsim hluav taws xob.

Anti-oxidation/dej countermeasure: Txais dej vapor siab barrier zaj duab xis rau ib lub hnab qhwv ib ncig.

Khoom nta

Quantum dot zaj duab xis raws li cov khoom siv nano tshiab nrog cov yam ntxwv lub teeb tshwj xeeb, tuaj yeem ua kom raug thiab ua haujlwm zoo hloov lub zog xiav lub teeb rau hauv lub teeb liab thiab ntsuab, quantum dots tuaj yeem tsim ib zaj duab xis nyias ntawm LED backlight ntawm LCD zaub, nrog xiav LED irradiation tuaj yeem tawm tag nrho cov spectrum ntawm lub teeb, los ntawm kev hloov kho ntawm lub teeb pom kev zoo, tuaj yeem txhim kho cov xim gamut kev ua tau zoo, kom cov xim zoo dua.

Quantum dot zaub thev naus laus zis tau hloov kho ntau yam hauv ntau qhov ntev xws li cov xim gamut, xim tswj qhov tseeb, xim liab, ntsuab, thiab xiav xim purity, thiab lwm yam. kiv puag ncig cuam tshuam rau lub ntiaj teb. Piv nrog rau cov khoom siv LCD, cov xim gamut ntawm quantum dot zaub tuaj yeem ncav cuag 110%.

Quantum dot zaj duab xis yog dav xim gamut tshwj xeeb optical zaj duab xis ua los ntawm quantum dots, barrier resin, thiab optical qib hydroxide barrier zaj duab xis ua cov ntaub ntawv tseem ceeb, ua ke nrog cov txheej txheem siab precision.

Cov txiaj ntsig khoom

Qhov zoo ntawm quantum dot zaj duab xis tuaj yeem muab sau ua "siab, ntshiab, thiab ruaj khov" peb yam tseem ceeb.

"High" yog lub siab xim gamut, raws li tus qauv NTSC, xim gamut ntawm LED TV zoo tib yam tsuas yog 72%, thawj tiam ntawm cov xim siab gamut TV tsuas yog 82%, OLED zaub tuaj yeem ncav cuag 100%, thaum xim gamut kev pab them nqi ntawm quantum dot TV yog mus txog 110%.

"ntshiab" yog xim ntshiab, xim purity dua li LED zoo tib yam los txhim kho ntau tshaj 50%, qhov tseeb ntawm cov xim ntuj;

"Stable" yog kev ua haujlwm ruaj khov, lub neej ntev ntawm zaj duab xis, ruaj khov inorganic nano-cov ntaub ntawv ntawm quantum dots tuaj yeem ua kom cov xim tsis tu ncua thiab tsis ploj mus, xim ntev thiab ruaj khov mus txog 60, 000 teev.

Quantum Dot Zaj duab xis ua li cas?

Quantum dot cov ntaub ntawv yog rhiab heev rau cov dej vapor thiab oxygen vim lawv cov khoom tshwj xeeb, yog li yuav tsum tau siv cov yeeb yaj kiab siab rau cov txheej txheem encapsulation. Thaum txheej txheej, peb yuav tsum txiav txim siab tsis yog tsuas yog kev tswj hwm ntawm txheej txheej, tab sis kuj tag nrho cov tuab tom qab lamination rau hauv cov qauv sandwich. Tam sim no quantum dot zaj duab xis txheej thickness feem ntau yog nyob ib ncig ntawm 50-100um, thiab cov txheej txheem loj no tuaj yeem siv rau ntau txoj hauv kev xws li comma, yob txheej, thiab hlais.

Ib txoj kev zoo tshaj plaws txheej txheej yog slit txheej. Slit txheej yog lub hauv paus ntsiab lus ntawm nws txoj haujlwm yog txhawm rau tso cov kua dej rau hauv ib qho pwm uas tuaj yeem kis tau cov kua dej sib npaug. Nws yog qhov kaw kaw thiab qhov thib ob, nws yog pre-metering cov khoom txheej los ntawm kev siv lub twj tso kua mis precision.

Nws yog raws li ob lub ntsiab lus uas cov txheej txheem slit txheej muaj qee qhov zoo uas lwm cov txheej txheem txheej tsis muaj: ntau txheej txheej hnyav thiab tag nrho kev faib khoom; yooj yim hloov ntawm tuab thiab nyias txheej txheej txheem; Kev txo qis cov pa tawm tsis zoo, txheej txheej paug, cov khoom siv raw khoom pov tseg, thiab kev ntxhov siab hauv chaw ua haujlwm.

Vim lub siab txheej txheej, lub ntim extrusion tuaj yeem tswj tau los ntawm lub zog lub cev muaj zog ceev ntawm precision metering twj tso kua mis lub cev, ua kom lub voj kaw. Nrog rau qhov system nro, kev sib hloov ceev ntawm lub slit txheej lub taub hau lub kua nplaum pub lub cev muaj zog yog lub luag haujlwm ntawm quantum dot film thickness. Lub thickness ntawm quantum dot zaj duab xis tau kuaj pom hauv online ntawm lub sijhawm tiag tiag, thiab tom qab cov kev suav nrog, nws tau rov qab mus rau lub tshuab nqus dej ntawm lub taub hau lub taub hau. Los ntawm kev hloov qhov ceev ntawm cov kua nplaum lub cev muaj zog, lub thickness ntawm quantum dot zaj duab xis tuaj yeem tswj tau qhov tseeb.
