Kutenga TV kwakatonyanya kuoma gore rino. MaTV ane LCD, QLED, Mini-LED, OLED uye, nguva pfupi yadarika, QD-OLED matekinoroji aripo. Mukutanga kwegore, Samsung yakaunza yambotaurwa QD-OLED kuratidza tekinoroji (yakatanga kuunzwa neSamsung S95B TV), iyo yainoti iri nani munzira dzakawanda kupfuura tekinoroji yeWRGB OLED inoshandiswa neanokwikwidza LG's TVs. Asi ndizvo zvazviri chaizvo here?
Unogona kufarira
QD-OLED imhando yekuzviburitsa-emission kuratidza, yakafanana neiyo Super AMOLED kuratidza inowanikwa muma smartphones uye mahwendefa. Galaxy. Izvi zvinoreva kuti pixel yega yega muQD-OLED pani inogona kuvheneka yega uye kugadzira yayo ruvara. Mukuwedzera, ine quantum dot nanocrystals, iyo inozivikanwa kune zviri nani kupenya zvivakwa, yakadzika mavara uye yakafara pendi yemavara.
A WRGB OLED kuratidzwa kunoshandisa chena backlight inopfuura nemuchena, tsvuku, girinhi, uye yebhuruu mafirita eruvara kuburitsa iwo anoenderana mavara. Kune zvakare chena subpixel. Chimwe chechiedza (kupenya) chinorasika apo chinopfuura nemumasefa emavara, zvichikonzera kupenya kwakaderera. Mukuwedzera, iyo chena backlight haina kunyatsojeka, saka mavara aanogadzira haana kuchena uye akazara.
Iyo organic zvinhu inoshandiswa muOLED skrini inogona kudzikisira nekukurumidza kana yakafumurwa kune yakareba-yakakwirira mazinga ekupenya. Saka LG inofanirwa kungwarira kuti inokwanisa kuchengetedza kupenya kwakakwira, kunyanya ine HDR yemukati. MaOLED TV saka kazhinji anodzima mushure memaminitsi mashoma.
QD-OLED tekinoroji, mukusiyana, inoshandisa yakachena yebhuruu backlight iyo inopfuura nepakati peiyo quantum dots kugadzira tsvuku, girinhi, uye bhuruu mavara. Quantum dots inotora simba kubva kune chero mwenje sosi, ichigadzira yakachena mono-frequency mwenje. Saizi yemadotsi e quantum inosarudza kuti ndeapi mavara nanoparticles avanoburitsa. Semuenzaniso, avo vane saizi ye2 nm vanoburitsa mwenje weblue, nepo vane saizi ye3 ne7 nm vanogona kuburitsa girini uye dzvuku chiedza. Nekuti ivo vanogadzira yakachena mono-frequency mwenje, kubereka kwemavara kweQD-OLED pani kuri nani pane kuya kweOLED skrini.
Sezvo kurasikirwa kwebacklight kuri kushoma neQD-OLED mapaneru, ivo vanowana zvakanyanya kubva mairi uye vanowanzo penya kupfuura WRGB OLED skrini. Uye zvakare, ivo vanopa yakadzika mavara, yakafara zvishoma maenga ekuona uye haanyanyi kutarisana nepixel kupisa-mukati. QD-OLED ndiyo chaiyo yekutanga OLED tekinoroji inosangana zvizere neiyo Ultra HD Premium kupenya kwepamusoro uye mutsauko wakatarwa neiyo UHD Alliance.
Nehunyanzvi hweQD-OLED, Samsung yakaunza hunyanzvi hunobatika kuchikamu cheOLED TV. Ikozvino isu tinongofanira kumirira QD-OLED TVs kudonha mumutengo kusvika padanho revamwe vavo veOLED, izvo hazvifanirwe kutora anopfuura makore mashoma.
Uye LG ine WOLED zvakare… 🙂
