Impande LED na Direct LED matrix yinyuma yinyuma – nibyiza nibihe bitandukanye

Guhitamo LCD LED TV nigisubizo kizamara imyaka myinshi, ugomba rero kwitondera ibipimo byacyo mbere yo kugura. Iparadizo, ingano nini ya ecran na 4K ikemurwa ntabwo buri gihe yemeza ubwiza bwibishusho. Muri iyi nyandiko, tuzasobanura itandukaniro riri hagati ya Edge LED na tekinoroji ya LED.

Ubwoko bwamatara ya Matrix muri LCD LED TV

Kuva mu mpera z’imyaka ya za 90, kwerekana LCD byatangiye gusimbuza ecran ya CRT, ibasunika rwose ku isoko. Twababwira iki nyuma yimyaka irenga makumyabiri tumaze murugo rwacu? LCD TV na monitor ntibitakaza gukundwa kandi biracyari hejuru. Yaba plasma ya ecran, cyangwa moda ya vuba OLED yabarenze. https://cxcvb.com/texnika/televizor/texnology/amoled-ili-ips-chto-luchshe.html Mu myaka yashize, gusa ubwoko bwo kumurika matrix bwarahindutse. Mbere, amatara akonje ya cathode fluorescent (CCFL) yakoreshwaga kugirango ayamurikire, uyumunsi arakoreshwa cyane cyane diode itanga urumuri (LED). Urebye kubitangwa kumurongo, ntuzabura guhura nijambo LED TV. Wibuke ko iyi ari LED isubira inyuma LCD TV kandi ntaho ihuriye na tekinoroji ya OLED.

1. LED itaziguye – diode ishyirwa munsi ya matrix kandi igakomeza kumikorere yose ya TV. Kubijyanye no kumurika mu buryo butaziguye, ababikora akenshi bakoresha ibizwi nka dimingi yaho kugirango bagere kubirabura byimbitse.
2. Impande LED – LED zishyirwa kumpera ya matrix. Iki nigisubizo cyokuzigama imbaraga, ariko nkuko uzabibona nyuma, biganisha kumurongo utaringaniye.

Ikibanza cya LED gifite ingaruka zikomeye kumiterere yishusho. Mu bindi bice, tuzagerageza kuganira kuri buri tekinoroji muburyo burambuye kandi tubone igisubizo cyikibazo cya Edge LED cyangwa Direct LED.

LED itaziguye – matrike ya LED igaragara kuri TV

Direct LED ya dimingi ni tekinoroji igezweho itanga abirabura byimbitse. Binyuze mu gukoresha urumuri rwinyuma, ishusho ibona ubuziranenge butaboneka kuri TV zisanzwe DLED. Itandukaniro ryo hejuru riragerwaho. Ahantu horoheje hacuramye kwigenga, hasigara ahantu heza hagaragara neza. Ubu ni ubundi buryo bwiza kubashaka TV ya LED ariko ntibashaka kwihanganira ibibi bya Directeur cyangwa Edge. Mubisobanuro bya TV, ushobora gusanga ijambo ryuzuye Array Local Dimming (Samsung ikoresha ijambo Direct Full Array), ibi ntakindi kirenze itara ryerekanwa rifite zone. Bashyizwe muri TV zo hagati kandi zohejuru. Muri moderi zihenze cyane, uzasangamo zone zigera ku 1000, muri zihendutse, mubisanzwe 50-60 gusa.

Ibyiza nibibi byo kumurika bitaziguye

Ibisanzwe DLED-itara ryinyuma rifite ibibi byinshi usibye kumurika matrix. Televiziyo ifite tekinoroji ya Direct LED cyane cyane ifite ibibazo byumukara, kuri ecran zabo akenshi zifata igicucu cyumukara. Nyamara, LED itaziguye ntabwo ari mbi iyo ihujwe na dimming yaho. Ikuraho byinshi mubitagenda neza byikoranabuhanga rishingiye. Amashusho akomeza kuba meza kandi yoroheje, mugihe igicucu gifata ubujyakuzimu.

Televiziyo 3 zigezweho hamwe na LED itaziguye

Samsung UE55TU7097U

Iyi ni 55 “4K LED TV ishyigikira HDR10 + na HLG. Moderi ifite ibikoresho bya Crystal 4K, itanga ubuziranenge bwibishusho hamwe namabara asanzwe. Sisitemu yo Kuzamura Imikino ni ingirakamaro kubakina, iremeza kwinjiza bike. UE55TU7097U nayo ifite urutonde rwuzuye rwa tuneri, kandi kugenzura ibintu byinshi-kurebera kure byoroshye kugenzura TV yawe hamwe nibikoresho bihujwe, mugihe Tizen System 5.5 iguha uburyo bworoshye bwo kubona ibintu byinshi byubwenge bwa TV. Ibipimo bya TV hamwe na stand: 1231x778x250 mm.

Sony KD-55X81J

Ubu ni moderi ya santimetero 55 ifite ibikoresho bya sensor ya 4K ifite umuvuduko wa Hz 120, byemeza neza neza. Uruganda narwo rwitaye ku bwiza bwarwo mu guha ibikoresho HDR10 +, Dolby Vision na HLG, ndetse n’umushinga wa HCX Pro AI, bitewe n’ubwenge bw’ubukorikori, uzahita utezimbere ishusho kugira ngo ugere ku ngaruka nziza. Ibipimo bya TV bifite igihagararo: 1243x787x338 mm.

Xiaomi Mi TV P1

Iki nigikoresho kigezweho gifite ecran ya 32-ya LED ya LED hamwe nigipimo cya 60 Hz. Tekinoroji ya matrix ikoreshwa hano iremeza ubwiza bwibishusho bidasanzwe hamwe nubutunzi bwamabara, harimo abirabura benshi. Ibipimo bya TV bifite igihagararo: 733x479x180 mm.
LED cyangwa Edge LED, itara ryinyuma guhitamo ninde wanga: https://youtu.be/P0CCeS9R6yU

Impande LED – ni iki?

Muri TV zifite tekinoroji ya Edge LED, diode yumucyo wera ishyirwa kumpera ya matrix gusa (muburyo buhendutse, iyi ishobora kuba imwe cyangwa ebyiri). Kugirango urumuri ruva kuri LED rugere ahantu kure cyane, hakenewe module ya LGP ​​kugirango ikwirakwizwe. Backlit Edge LED ya ecran iroroshye ariko ifite ibibazo byo kumurika kimwe. Umurongo umwe wa LED ntabwo uhagije kugirango umurikire neza ibintu byose byerekanwe, ndetse na module idasanzwe ntabwo ifasha cyane hano. Mubisanzwe, ishusho izaba imurika kumpera kuruta hagati. Igihe kimwe, uduce twirabura ntituzaba umwijima nkuko bikwiye. Nyamara, Edge LED TV zifite igipimo cyiza cyo kugereranya kuruta TV zisanzwe zisubira inyuma.

Ibyiza nibibi byo kumurika

Bitewe numubare muke wa LED, Edge LED TV zirahendutse gukora. Batangaza ubunini bwa ecran, busa neza imbere. Impande LED igarukira mugihe cyo kubyara amabara asanzwe. Kugirango ibintu birusheho kuba bibi, Edge LED ntabwo aribwo buryo buhendutse cyane kuko ikoranabuhanga risaba module yihariye ya LGP.
