Nekuvandudzwa kwehunyanzvi hwekuratidzira, iyo TFT-LCD indasitiri, iyo yakatonga indasitiri yekuratidzira kwemakumi emakore, yakapikiswa zvakanyanya.OLED yakapinda mukugadzirwa kwemazhinji uye yakagamuchirwa zvakanyanya mumunda wemafoni.Emerging matekinoroji akadai seMicroLED neQDLED zvakare ari mukutenderera kuzere.Shanduko yeindasitiri yeTFT-LCD yave maitiro asingadzoke Pasi peiyo ine hukasha yeOLED yakakwira-kusiyana (CR) uye yakafara color gamut hunhu, iyo TFT-LCD indasitiri yakatarisana nekuvandudza hunhu hweLCD color gamut uye yakaronga pfungwa ye "quantum". dot TV."Nekudaro, iyo inonzi "quantum-dot TVs" haishandise maQD kuratidza zvakananga maQDLED.Pane kudaro, ivo vanongowedzera QD firimu kune yakajairwa TFT-LCD backlight.Basa reiyi QD firimu nderekushandura chikamu chechiedza chebhuruu chinoburitswa nebacklight kuita girini uye tsvuku mwenje ine nhete yewavelength kugovera, iyo yakaenzana neyakafanana neyakajairwa phosphor.

Chiedza chegirini uye dzvuku chinoshandurwa nefirimu reQD chine chidimbu chewavelength kugovera uye chinogona kunyatsoenderana neCF high light transmittance band yeLCD, kuitira kuti kurasikirwa kwechiedza kuderedze uye kumwe kushanda kwechiedza kunogona kuvandudzwa.Kupfuurirazve, sezvo kugoverwa kwewavelength kuri kutetepa, RGB monochromatic mwenje ine yakakwira kuchena kwemavara (saturation) inogona kuitika, saka iyo gamut yemuvara inogona kuve yakakura Naizvozvo, tekinoroji ye "QD TV" haisi kukanganisa.Nekuda kwekuzadzikiswa kwekushandurwa kwefluorescence ine yakamanikana luminescent bandwidth, yakajairika phosphors inogonawo kuitika.Semuyenzaniso, KSF:Mn inodhura-yakaderera, nhete-bandwidth phosphor sarudzo.Kunyangwe KSF: Mn inotarisana nematambudziko ekugadzikana, kugadzikana kweQD kwakaipisisa kupfuura kweKSF: Mn.

Kuwana yakakwirira-yakavimbika QD firimu hakusi nyore.Nekuti QD inoratidzwa kumvura uye okisijeni mumhepo mumhepo, inokurumidza kudzima uye kupenya kunopenya kunodonha zvakanyanya.Mushonga wekudzivirira mvura uye neokisijeni-uchapupu hwekudzivirira kwemufirimu weQD, uyo unogamuchirwa zvakanyanya parizvino, ndeyekusanganisa iyo QD muglue kutanga, wobva waisa sandwich glue pakati pezvikamu zviviri zvemafirimu epurasitiki anodzivirira mvura uye oxygen-proof. gadzira chimiro che "sandwich".Iyi firimu yakaonda mhinduro ine mutete mukobvu uye iri padyo neiyo yekutanga BEF uye mamwe optical firimu maitiro eiyo backlight, iyo inofambisa kugadzirwa uye kusangana.

Muchokwadi, QD, sechinhu chitsva chinopenya, inogona kushandiswa senge photoluminescent fluorescent inoshandura zvinhu uye inogona zvakare kuvezwa yakananga magetsi kuburitsa mwenje.Iko kushandiswa kwenzvimbo yekuratidzira kwakatonyanya kupfuura nzira yeQD firimuSemuyenzaniso, QD inogona kuiswa kuMicroLED se fluorescence conversion layer yekushandura mwenje weblue kana violet light inoburitswa kubva muLED chip kuita monochromatic light yemamwe wavelengths.Sezvo saizi yeLED iri kubva pagumi nembiri mamicrometer kusvika makumi akati wandei emamicrometer, uye saizi yeakajairwa phosphor particles ari mashoma gumi nemaviri mamicrometer, saizi yefosphor yakajairwa iri padyo neiyo imwechete chip saizi yeLED. uye haigone kushandiswa se fluorescence shanduko yeMicroLED.zvinhu.QD ndiyo yega sarudzo yefluorescent color conversion zvinhu zvino shandiswa pakuita colorization yeMicroLEDs.

Pamusoro pezvo, iyo CF iri muLCD sero pachayo inoshanda sesefa uye inoshandisa chinhu chinotora chiedza.Kana iyo yepakutanga-inotora mwenje zvinhu yakatsiviwa zvakananga neQD, inovhenekera yega QD-CF LCD sero inogona kuitika, uye kugona kwekuona kweTFT-LCD kunogona kuvandudzwa zvakanyanya uku uchiwana yakafara color gamut.

Muchidimbu, quantum dots (QDs) ine tarisiro yakakura kwazvo yekushandisa munzvimbo yekuratidzira.Parizvino, iyo inonzi "quantum-dot TV" inowedzera firimu reQD kune yakajairwa TFT-LCD backlight source, inongori kuvandudzwa kweLCD TVs uye haina kunyatsoshandisa zvakanakira QD.Zvinoenderana nekufanotaura kwesangano rekutsvagisa, tekinoroji yekuratidzira yeyakajeka color gamut ichaumba mamiriro umo magiredhi epamusoro, epakati uye akaderera uye marudzi matatu emhinduro achange aripo mumakore anotevera.Pakati uye yakaderera giredhi zvigadzirwa, phosphors uye QD firimu inoumba hukama hwemakwikwi.Muzvigadzirwa zvepamusoro-soro, QD-CF LCD, MicroLED uye QDLED ichakwikwidza neOLED.
