Tekinoroji Yemazuva Ano Yekuratidzira MaTerevhizheni Ane Mapaneru eLED
Terevhizheni yakachinja nekukurumidza mumakore gumi apfuura, kunyanya muhunyanzvi hwekuratidzira. Kunyange zvazvo CRT TV dzaimbove dzakajairika, ndokuzochinjwa kuita LCD, izwi rekuti "LED TV" rave kushandiswa mudzimba dzakawanda. Zvisinei, shure kwezita rekuti "LED" pacharo kune matekinoroji akasiyana-siyana epaneru uye masisitimu emwenje ari kuramba achichinja. Tekinoroji yekuratidzira yazvino mumaterevhizheni e-LED-paneru haingotaridzi chete pamifananidzo yakajeka asiwo pakuenzanisa kwakadzama, mavara akanyatsojeka, kushanda nesimba, uye magadzirirwo matete ari kuwedzera.
Kunzwisisa Izwi rekuti "TV ye LED": Panel vs Backlight
Chekutanga, zvakakosha kunzwisisa kuti maTV mazhinji anonzi "LED TVs" achiri kushandisa LCD (Liquid Crystal Display) panels. LED, muchirevo ichi, inoreva backlight source inovhenekera LCD panel. LCD panels hadziburitse chiedza pachadzo, saka dzinoda backlight. Ichi ndicho chikonzero nei tekinoroji ye LED mumaterevhizheni ichiramba ichichinja: nekuti hunhu hwemufananidzo hunokanganiswa zvakanyanya nekutonga kunoita backlight.
Muzvizvarwa zvekare, mwenje we LED waiiswa pamativi echidzitiro (waivhenekerwa ne edge-light). Iye zvino, maitiro acho ari ekushandisa masisitimu akaomarara akadai se full-array, local dimming, mini-LED, uye nzira itsva dzekuvandudza ruvara nekusiyana.
1. LED yakazara uye kudzima kwenzvimbo: Kudzora Mwenje Kwakanyatsonaka
Imwe yenzira huru dzekuvandudza maTV akagadzirwa ne LED i Full-Array LED (FALD). Kusiyana nemaTV ane edge-light, ayo anongoisa ma LED pamipendero yechidzitiro, FALD inoisa ma LED zvakaenzana kuseri kwechidzitiro. Zvakanakira zvikuru mwenje wakafanana uye musiyano uri nani.
Tekinoroji iyi inowedzerwawo nekudzima kwenzvimbo, izvo zvinokutendera kuti udzimise kana kupenya nzvimbo dzakati dzechidzitiro zvichienderana nezvinodiwa nemufananidzo. Semuenzaniso, kana uchiratidza chiitiko chehusiku chine mwedzi wakajeka, nzvimbo yakatenderedza mwedzi inogona kupenya nepo denga rakatenderedza richisviba. Izvi zvinoguma nekuwedzera kwemumvuri uye matema akadzika zvichienzaniswa neTV ye LED yakajairwa.
Zvisinei, kudzima kwenzvimbo muFALD kuchiri kukonzera matambudziko muchimiro chemaruva kana kuti halo effects, izvo zviri kudonha kwechiedza kwakatenderedza zvinhu zvinopenya pamashure matema. Kuti vagadziri vaderedze izvi, vari kuwedzera huwandu hwenzvimbo dzinodzima uye vachinatsa maalgorithms ekudzora mwenje.
2. Mini-LED: Kuchinja Kukuru muTV dzemazuva ano dzeLED
Tekinoroji inonyanya kuzivikanwa mumaTV emazuva ano eLED iMini-LED. Zvichitaurwa zviri nyore, Mini-LED iLED diki zvikuru pane LED yakajairika. Nekuda kwehukuru hwayo hudiki, huwandu hwakawanda hwemaLED hunogona kuiswa kumashure kwepaneru, zvichiwedzera zvakanyanya huwandu hwenzvimbo dzekunze dzisina chiedza.
Zvakanakira zve mini-LED zvinosanganisira:
- Kusiyana kwakanyanya nekuti kune nzvimbo dzakawanda uye dzakasimba dzekudzima chiedza.
– Kutumbuka kwemaruva kunoderera nekuda kwekudzora chiedza kwakanyatsojeka.
– Kupenya kwakanyanya, kwakakodzera HDR.
– Yakachengeteka kubva panjodzi yekutsva kupfuura matekinoroji anoburitsa chiedza pa pixel imwe neimwe senge OLED.
Mini-LED inowanzoonekwa se "bhiriji" pakati pemaTV echinyakare e LED netekinoroji yekuratidza inoburitsa zvinhu yoga. Kune vashandisi vanokoshesa kupenya kwakanyanya munzvimbo dzakapenya, mini-LED isarudzo yakasimba kwazvo.
3. Quantum Dot (QLED): Kukwira kweRuvara
Kunze kwekusiyana, kunaka kwemavara ndicho chinhu chikuru chinotarisirwa. Apa ndipo panopinda Quantum Dots. MaTV, anowanzo kutengeswa seQLED, anowanzo sanganisa LCD panel ne LED backlight ne quantum dot layer. Iyi layer ine nanoparticles dzinogona kushandura backlight light kuita purple color spectrum.
Mhedzisiro yacho ndeiyi:
– Mavara acho akajeka uye akajeka, kunyanya matsvuku negirini.
– Hurumu yeruvara inowedzera, zvichireva kuti mavara anoramba akajeka kunyangwe paine kupenya kwakanyanya.
- Kushanda kweHDR kuri nani nekuda kwekusanganiswa kwakasimba kwemavara nekupenya.
QLED haisi tekinoroji ye backlight chete, asi sisitimu yemavara yakagadziridzwa inoshanda pamwe chete nema LED senzvimbo yechiedza. MaTV mazhinji emini-LED anewo ma quantum dots kuti ashande zvakanaka.
4. HDR yechizvarwa chinotevera: Inonyatsooneka paTV dzemazuva ano dze LED
Tekinoroji yemazuva ano yekuratidza zvinhu ine hukama hwakasimba neHDR (High Dynamic Range). Chinangwa cheHDR ndechekuratidza chiedza nerima, zvichiita kuti mifananidzo iite seyechokwadi. MaTV emazuva ano eLED, kunyanya ane mamini-LED uye ane rima rakanaka, anokwanisa kuratidza zvinhu zvinopenya (sekupenya kwezuva, mwenje yemotokari, kana kupenya kwesimbi) zvinogutsa.
Mafomati akajairika eHDR anotsigirwa nemaTV emazuva ano anosanganisira:
- HDR10 (chiyero chinowanzo shandiswa)
– HLG (inoshandiswa zvakanyanya mukuparadzira)
- Dolby Vision uye/kana HDR10+ (dynamic HDR inogadzirisa pachiitiko chimwe nechimwe)
Ne dynamic HDR, kupenya uye metadata yemavara zvinogona kugadziriswa pachiitiko chega chega, kuitira kuti ruzivo rusaburitswe munzvimbo dzakajeka kana kurasika munzvimbo dzine rima.
5. High Refresh Rate uye Gaming Features: 120Hz, VRR, uye ALLM
Materevhizheni emazuva ano haasi ekuona mafirimu chete, asiwo ekutamba mitambo. Tekinoroji yemazuva ano ye LED display ine zvinhu zvakawanda zvaimbowanikwa chete pamamonita emitambo.
Zvimwe zvinhu zvakakosha:
- 120Hz refresh rate (kana kupfuura pane mamwe mamodheru) kuti ifambe zvakanaka.
– VRR (Variable Refresh Rate) kuitira kuti mufananidzo usabvaruke kana frame rate ikachinja.
– ALLM (Auto Low Latency Mode) yekudzikisa otomatiki kunonoka kwekupinda kana koni yaonekwa.
- Kugadzirisa kufamba uye kugadzirisa kufamba kwakangwara (kunyangwe vamwe vanhu vachisarudza kuidzima pamafirimu).
Kusanganiswa kwemini-LED/QLED ne120Hz kunoita kuti maTV emazuva ano eLED ave nani pamitambo, mafirimu emitambo, uye mitambo yemakwikwi.
6. Algorithm yeKugadzirisa Mifananidzo Yakavakirwa paAI
Kunze kwepaneru, hunhu hwemufananidzo hunokanganiswa zvakanyanya ne "uropi" hweterevhizheni, iyo inogadzirisa mifananidzo. Kambani itsva inoshandiswa pakuwedzera saizi yeAI uye kuongorora otomatiki nzvimbo. Iyi tekinoroji inokwanisa kuita zvinotevera:
- Inosimudzira zviri mukati zvine resolution yakaderera kuti zvionekwe zvakadzama mu4K kana 8K.
- Inoderedza ruzha nenzira inochinjika uye inowedzera kupinza.
- Gadzirisa ruvara, gamma, uye musiyano zvichienderana nerudzi rwezviri mukati.
- Inogadzirisa kudzima kwenzvimbo kuti kuchinja pakati penzvimbo kuve kwechisikigo.
Kunyange zvazvo mhedzisiro yacho ichienderana nemhando yepurosesa nemavhidhiyo, kugadziriswa kwemifananidzo kuri nani kunoita kuti maTV emazuva ano eLED aenderane nemarudzi akasiyana ezvinyorwa.
7. Kugadzira Panel uye Kushanda Nesimba Zvakanaka
MaTV e LED achangoburwa anouyawo nemagadzirirwo akatetepa uye mashandisirwo asingadhuri simba. Mamini-LED anogona kuwedzera kuoma kwechimiro, asi kushanda kwawo zvakanaka uye manejimendi esimba akangwara zvinobatsira kuderedza kushandiswa kwesimba. Pamusoro pezvo, vagadziri vazhinji vanosanganisira nzira dzinochengetedza simba uye masensa emwenje ekugadzirisa kupenya zvichibva pamwenje wemukamuri.
Panyaya yekugadzirwa, mabezel ari kuramba achiwedzera kutetepa, manejimendi yetambo yanyatsonaka, uye mamwe mamodheru ane pfungwa ye "gallery design" saka anotaridzika kunge akabatana nemukati.
Mhedziso
Tekinoroji yemazuva ano yekuratidzira materevhizheni e LED inodarika izwi rekuti "LED." Kushanduka kwayo kunosanganisira kuvandudzwa kwemwenje wekumashure (full-array, local dimming, mini-LED), kuvandudzwa kwemavara (quantum dot/QLED), rutsigiro rwe dynamic HDR, mwero wepamusoro wekuzorodza mitambo, uye kugadziriswa kwemifananidzo kwakavakirwa paAI. Kune vatengi, kunzwisisa matekinoroji aya kunovabatsira kusarudza TV yakakodzera: mini-LED yekusiyanisa kwakasimba uye HDR, quantum dot yemavara akapfuma, uye 120Hz neVRR kuti mutambo uve wakatsetseka.
Pakupedzisira, maTV e LED anoramba ari sarudzo yakakurumbira nekuti anopa kuenzana kwemhando yemifananidzo, kupenya kwakanyanya, hupenyu hurefu, uye mitengo iri kuramba ichikwikwidzana. Nekuenderera mberi kwekuvandudzwa, maTV e LED emazuva ano ari kuswedera pedyo nekuona kwepamusoro-soro kana tekinoroji yepamusoro chete yaigona kuwanikwa.
