Isesengura ry'ejo hazaza rya tekinoroji ya Quantum

Hamwe niterambere ryikoranabuhanga ryerekana, inganda za TFT-LCD, ziganje mu nganda zerekana imyaka mirongo, zarahanganye cyane.OLED yinjiye mubikorwa byinshi kandi byemewe cyane mubijyanye na terefone.Tekinoroji igaragara nka MicroLED na QDLED nayo irarimbanije.Guhindura inganda za TFT-LCD byahindutse inzira idasubirwaho Mugihe gikabije cya OLED itandukanye cyane (CR) hamwe n’imiterere yagutse ya gamut, inganda za TFT-LCD zibanze ku kunoza ibiranga umukino wa LCD kandi zitanga igitekerezo cya "kwantum akadomo kuri TV. "Ariko, ibyo bita "TV-Dot TV" ntibikoresha QD kugirango berekane QDLEDs.Ahubwo, bongeraho gusa QD firime kumurongo usanzwe wa TFT-LCD.Imikorere yiyi firime ya QD nuguhindura igice cyurumuri rwubururu rutangwa numucyo winyuma ugahinduka urumuri rwatsi nicyatsi gitukura hamwe nogukwirakwiza kwizuba ryumurambararo, ibyo bikaba bihwanye ningaruka zimwe na fosifori isanzwe.

Itara ry'icyatsi n'umutuku ryahinduwe na firime ya QD rifite uburebure buke bwo gukwirakwiza kandi birashobora guhuzwa neza na CF yohereza urumuri rwinshi rwa CFD ya LCD, kugirango igihombo gishobora kugabanuka kandi imikorere yumucyo irashobora kunozwa.Byongeye kandi, kubera ko ikwirakwizwa ry’umurongo ari rito cyane, urumuri rwa RGB rufite urumuri rwinshi (saturation) rushobora kugaragara, bityo umukino wamabara urashobora kuba munini Kubwibyo, iterambere ryikoranabuhanga rya "QD TV" ntirishobora guhungabanya.Kuberako hamenyekanye ihinduka rya fluorescence hamwe numuyoboro mugari wa luminescent, fosifori isanzwe nayo irashobora kugaragara.Kurugero, KSF: Mn nigiciro gito, kigufi-cyagutse cya fosifore.Nubwo KSF: Mn ihura nibibazo byumutekano, ituze rya QD ribi kurenza irya KSF: Mn.

Kubona firime yizewe cyane QD ntabwo byoroshye.Kuberako QD ihura namazi na ogisijeni mubidukikije mu kirere, irazimya vuba kandi imikorere yumucyo igabanuka cyane.Igisubizo cyokwirinda amazi hamwe na ogisijeni irinda igisubizo cya firime ya QD, yemerwa cyane muri iki gihe, ni ukubanza kuvanga QD muri kole, hanyuma sandwich ikomatanya hagati y’ibice bibiri byerekana amazi na firime ya ogisijeni kugeza kuri gukora imiterere ya "sandwich".Iki gisubizo cyoroshye cya firime gifite umubyimba muto kandi cyegereye BEF yumwimerere nibindi bintu bya optique biranga urumuri rwinyuma, byorohereza gukora no guterana.

Mubyukuri, QD, nkibikoresho bishya bimurika, irashobora gukoreshwa nkibikoresho bya fotoluminescent ya fluorescent kandi birashobora no guhabwa amashanyarazi kugirango bitange urumuri.Gukoresha ahantu herekanwa birenze kure uburyo bwa firime ya QDUrugero, QD irashobora gukoreshwa kuri MicroLED nkigice cyo guhindura fluorescence kugirango uhindure urumuri rwubururu cyangwa urumuri rwa violet ruva muri chip ya uLED ruhinduka urumuri rwa monochromatique yuburebure bwumuraba.Kubera ko ubunini bwa uLED buva kuri micrometero icumi kugeza kuri micrometero mirongo, kandi ubunini bwa fosifori busanzwe ni byibuze byibuze micrometero icumi, ingano ya fosifore isanzwe yegereye ubunini bwa chip imwe ya ULED kandi ntishobora gukoreshwa nka fluorescence ihinduka ya MicroLED.ibikoresho.QD niyo ihitamo ryonyine ryibikoresho byo guhindura ibara rya fluorescent ikoreshwa muguhindura amabara ya MicroLEDs.

Mubyongeyeho, CF muri selile LCD ubwayo ikora nkayunguruzo kandi ikoresha ibikoresho bikurura urumuri.Niba ibikoresho byumwimerere bikurura urumuri byasimbuwe na QD, selile-yonyine-QD-CF LCD selile irashobora kugaragara, kandi imikorere ya optique ya TFT-LCD irashobora kunozwa cyane mugihe ugera kumikino yagutse.

Muncamake, akadomo ka kwant (QDs) gafite ibyagutse cyane byerekanwa murwego rwo kwerekana.Kugeza ubu, icyo bita "quantum- dot TV" yongeraho firime ya QD kumasoko asanzwe ya TFT-LCD yamurika, ibyo bikaba ari ugutezimbere gusa TV za LCD kandi ntabwo yakoresheje neza ibyiza bya QD.Dukurikije ibiteganijwe mu kigo cy’ubushakashatsi, tekinoroji yo kwerekana ibara ryoroheje rya gamut izakora ibihe aho amanota yo hejuru, ayisumbuye na make hamwe nubwoko butatu bwibisubizo bizabana mumyaka iri imbere.Mu bicuruzwa byo hagati no hasi, ibicuruzwa bya fosifore na QD bigira isano yo guhatana.Mu bicuruzwa byo mu rwego rwo hejuru, QD-CF LCD, MicroLED na QDLED bazahatana na OLED.
