Kunyange zvazvo kare vanhu vaingoziva LCD ne LED semashoko akajairwa, ikozvino mazita matsva akasiyana-siyana abuda, akadai seOLED, Mini-LED, uye QLED. Pakati pesarudzo idzi, QLED yave imwe yematekinoroji anoshandiswa zvakanyanya mumaterevhizheni epakati kusvika epamusoro nekuti inopa mavara anopenya, mwero wekupenya kwakanyanya, uye kugara kwenguva refu kwechiso. Zvisinei, vanhu vazhinji vachiri kushamisika kuti: mapaneru eQLED anoshanda sei chaizvo mumaterevhizheni matsva? Chinyorwa chino chichakurukura misimboti yekutanga yeQLED, zvikamu zvinobatanidzwa, uye zvakanakira nekugumira kwayo.
Chii chinonzi QLED?
QLED inomirira Quantum-dot Light Emitting Diode. Kunyangwe zita racho riine izwi rekuti "LED," QLED haisi tekinoroji yekuratidza "inoburitsa yega" seOLED. Kazhinji, QLED imhando yeLCD inoshandisa quantum dot layer kuvandudza kunaka kwemavara. Izvi zvinoreva kuti mapaneru eQLED achiri kushandisa backlight kugadzira chiedza, icho chinozogadziriswa kuburikidza nezvikamu zvakasiyana-siyana chisati chagadzira mufananidzo pachiratidziro.
Nekuda kwechikonzero ichi, QLED inowanzonzi LCD ine quantum dot enhancement. Mumaterevhizheni matsva, QLED inowanzo sanganiswa nemasystem emazuva ano emwenje akadai seFull Array Local Dimming (FALD) kana Mini-LED, zvichikonzera kushanda kuri nani kupfuura maLCD e LED akajairwa.
Zvikamu Zvikuru zveQLED Panel
Kuti tinzwisise mashandiro anoita QLED, tinofanira kutarisa kurongeka kwezvikamu zvakakosha mupaneru yeterevhizheni, zvinosanganisira:
1. Mwenje wekumashure
2. Plate yekutungamira chiedza / diffuser (diffuser yechiedza)
3. Quantum Dot Layer
4. Sefa yemavara
5. Rutivi rweCrystal yemvura
6. Polarizer (Sefa yePolarization)
7. TFT Layer (Pixel Control Transistor)
Rutivi rumwe nerumwe rune basa rarwo, uye zvese zvinoshanda pamwe chete kuti mufananidzo waunoona pachiratidziro uve wakajeka, wakapinza, uye wakarurama neruvara.
Matanho ekuti QLED Panel Inoshanda Sei
1. Chiedza chekumashure chinoburitsa chiedza chepakutanga
Nekuti QLED yakavakirwa paLCD, mwenje mukuru unobva kumwenje wekumashure. Chizvarwa chitsva chematerevhizheni eQLED chinowanzo shandisa maLED ebhuruu sechiedza chawo, sezvo blue spectrum ndiyo inonyanya kushanda pa "activation" quantum dots.
Mune mamwe marudzi, backlight inogona kuva:
– Yakavhenekerwa nemucheto: Ma LED ari pamucheto wechidzitiro, uye chiedza chinonanga pakati. Chitete uye chakachipa, asi kudzima kwenzvimbo kwakaderera.
– Yakavhenekerwa zvakananga / Yakazara: Ma LED akapararira zvakaenzana kuseri kwepaneru, zvichibvumira kudzora chiedza zviri nani.
– Mini-LED: vhezheni diki ye LED yenguva dzose, ine huwandu hwakawanda kwazvo, zvichibvumira kudzora kwakanyatsojeka kwenzvimbo yechiedza (nzvimbo yekudzikira kwechiedza).
Danho iri rinoona kuti TV inogona kupenya zvakadii, kunyanya kana uchiona zviri muHDR.
2. Chiedza chinopararira zvakaenzana
Kana mwenje wekumashure wabatidzwa, chiedza chinopfuura nemudhibhurawuza kana ndiro inotungamira chiedza. Rutivi urwu runogovera chiedza zvakaenzana kudzivirira nzvimbo dzakajeka kana dzakasviba (nzvimbo dzinopisa). Izvi zvinoita kuti chiratidzike zvakanaka pane skrini yese.
3. Chidimbu che quantum dot chinoshandura spectrum yechiedza.
Uyu ndiwo musimboti wetekinoroji yeQLED. Madotsi eQuantum zvimedu zvenanometer zvinogona kuburitsa chiedza pahurefu hwakati kana zvavhenekerwa. MuQLED, chiedza chebhuruu chinobva kuchiedza chekumashure chinosvika padanho requantum dot, uko chimwe chacho chinoshandurwa kuita chiedza "chitsvuku" negirini "chakachena".
Zviri nyore:
- Ma LED ebhuruu anogadzira chiedza chebhuruu chakasimba
- Madotsi eQuantum "anoshandura" rimwe rechiedza chebhuruu kuita dzvuku negirini.
- Mugumisiro wacho musanganiswa wakanaka kwazvo wema spectrum kuti ugadzire mavara akafara uye akapfuma.
Nekuti madotsi equantum anogadzira mavara ane spectrum yakamanikana (yakanyatsojeka), QLED inokwanisa kugadzira vhoriyamu yakanaka yemavara—ndiko kuti, mavara achiri kutaridzika akapfuma kunyangwe pahuwandu hwekupenya kwakanyanya.
4. Sefa yemavara inosefa ruvara kuita maRGB subpixels.
Mushure mekupfuura nepakati pe quantum dot, chiedza chinopfuura nepa color filter inokamura chiedza kuita zvikamu zvitatu zvikuru: tsvuku (R), girini (G), uye bhuruu (B). Pikseli yega yega iri pachiratidziro inoumbwa nema RGB subpixels matatu. Kubatanidzwa kwemavara aya kunoburitsa mamiriyoni kusvika mabhiriyoni emarudzi akasiyana-siyana.
Rutivi rwesefa yemavara runoshanda se "gedhi remavara", zvichiita kuti chiedza chinobuda mu subpixel yega yega chienderane neruvara rwaunoda.
5. Makristaro emvura anodzora kuti chiedza chinopfuura nepi.
Chikamu cheLCD (liquid crystal) ndicho chine basa rekudzora chiedza chepikisi yega yega. Makristaro emvura haaburitse chiedza, asi anotenderera divi re polarization yechiedza. Nerubatsiro rwema polarizers ari kumberi nekumashure, makristaro emvura anogona kudzora kana chiedza chichipfuudzwa kana kuvharwa.
Kana chiratidzo chemagetsi chikapihwa:
- Makristaro emvura anochinja maonero
- Kuchinja kwakanangana kunodzora mwero wechiedza chinogona kupfuura nepakati pemapikiseli.
- Izvi ndizvo zvinoumba mufananidzo werima-rima (wakasiyana) pachiratidziro.
Mapaneru emazuva ano eQLED anogona kushandisa mhando dzakasiyana dzeLCD, dzakadai seVA kana IPS, izvo zvinokanganisa hunhu hwechiratidziro senge kusiyana uye maangle ekuona.
6. TFT inodzora pixel yega yega nemazvo
Seri kwechikamu chegirazi remvura kune TFT (Thin Film Transistor) iyo inodzora voltage ye subpixel yega yega. TFT inoita basa rekuchengetedza kudzora ma pixel kwakasimba uye kwakaringana, ichidzivirira kukanganiswa kwemifananidzo senge kupenya, ghosting, kana kusagadzikana.
Kana TFT control uye image processing zviri nani, gradient transitions dzinoita kuti zvive nyore uye mabhandi mashoma pane zvimwe zviri mukati anoderedza.
Basa reKudzikisa Madhiraivha eMunharaunda paTV dzeQLED dzemazuva ano
Chimwe chezvinetso zvikuru nemaLCD nderekuti matema akaenzana. Nekuti anoshandisa backlight, chiedza chinogona kubuda, zvichiita kuti matema aite segrey. Kuti agadzirise izvi, maTV eQLED achangoburwa anowanzo shandisa local dimming: nzvimbo dzakatarwa dzebacklight dzinogona kudzimwa kana kudzimwa kuti dzienderane nezvinodiwa nemufananidzo.
Kana uchiratidza chiitiko chehusiku chine mwenje midiki:
- Nzvimbo dzemwenje wekumashure munzvimbo dzine rima dzakadzimwa
- Nzvimbo iri munzvimbo ine chiedza chakajeka ichiri kupenya zvakajeka
- Kusiyana kunowedzera uye ruzivo rwunoonekwa zvakanyanya
Mini-LED inoita kuti kudzima kwechiedza munzvimbo kushande zvakanyanya nekuti kune nzvimbo dzakawanda, saka mhedzisiro ye "halo" (inotumbuka) yakatenderedza zvinhu zvinopenya inogonawo kuderedzwa.
Mabhenefiti eQLED paTerevhizheni Dzazvino
1. Kupenya kwakanyanya
Yakakodzera makamuri akajeka uye HDR, sezvo ichikwanisa kugadzira magirazi akasimba uye akajeka.
2. Mavara akapfuma uye akasimba
Madotsi eQuantum anowedzera kuchena kwemavara, kusanganisira pakupenya kwakanyanya.
3. Njodzi shoma yekutsva
Nekuti haisi yega inoburitsa zvinhu zvayo seOLED, QLED inowanzo kuve yakachengeteka kune zviratidziro zvenguva refu (ma logo eTV, ma HUD emitambo).
4. Mitengo yakasiyana-siyana
Kune akawanda maQLED sarudzo pamitengo yakasiyana-siyana, kunyanya kana tichienzanisa nemaOLED epamusoro.
Zvipingamupinyi zveQLED Zvaunofanira Kuziva
1. Matema haana "kudzika" semaOLED
Nekuti kuchine mwenje wekumashure, dema rakazara rakaoma kuwana, kunyangwe kudzima kwenzvimbo kuchibatsira.
2. Kugona kukura
Muzviitiko zvine musiyano mukuru, zvinhu zvinopenya zvinogona kukonzera kuti chiedza "chibude" panzvimbo ine rima, kunyanya kana nzvimbo yacho iri shoma.
3. Kona yekuona inoenderana nerudzi rwepaneru
Mapaneru eVA anowanzova nemakona ekuona akasiyana asi akamanikana; IPS ndiyo yakasiyana.
Mhedziso
Mapaneru eQLED ari mumaterevhizheni azvino anoshanda nekubatanidza tekinoroji yeLCD nechikamu chequantum dot chinowedzera ruvara. Chiedza chinobva kumwenje wekumashure—kazhinji kacho chiri chebhuruu LED—chinogadziriswa nemadotsi equantum kuti chibudise mavara matsvuku negirini akachena, ayo anozodzorwa nemakristaro emvura uye sisitimu yeTFT transistor kuti igadzire mufananidzo. Mumamodeli azvino, QLED inowedzerwazve nekubatanidzwa nematekinoroji edhimimini emuno epamusoro akadai seFALD neMini-LED, zvichikonzera kuvandudzwa kwakanyanya kwekuenzanisa uye kushanda kweHDR.
Kune vashandisi vanoda TV ine mavara akajeka, anopenya uye inogara kwenguva refu yekushandisa zuva nezuva uye mitambo, QLED isarudzo inokwezva. Zvisinei, kana zvinhu zvaunonyanya kukoshesa zviri zvitema zvakakwana uye musiyano wakakura, tekinoroji yeOLED inoramba iri sarudzo inosarudzwa. Pakupedzisira, kunzwisisa mashandiro anoita QLED kunotibatsira kusarudza terevhizheni yakakodzera zvatinoda uye mamiriro emukamuri.
Kana muchida, ndinogona kuwedzera tafura inoenzanisa QLED vs OLED vs Mini-LED, kana kupa mazano pamusoro pezvakakosha pakusarudza QLED TV (kupenya kwe nits, huwandu hwenzvimbo dzinodzima, VA/IPS panel type, uye rutsigiro rweHDR).
