I-Edge ye-LED kunye ne-Direct LED matrix backlight iindidi-yeyiphi engcono kwaye yintoni umahluko

Ukukhetha i-LCD ye-TV ye-LED isisombululo esiya kuhlala iminyaka emininzi, ngoko kufuneka ubeke ingqalelo kwiiparameters zayo ngaphambi kokuthenga. Ngokumangalisayo, ubungakanani besikrini esikhulu kunye nesisombululo se- 4K akusoloko siqinisekisa owona mgangatho uphezulu wemifanekiso. Kule post, siza kuchaza umahluko phakathi kwe-Edge LED kunye ne-Direct Direct teknoloji ye-LED.

Iintlobo zezibane ze-Matrix kwii-TV ze-LCD ze-LED

Ukusukela ngasekupheleni kweminyaka yoo-1990, iziboniso zeLCD sele ziqalisile ukutshintsha izikrini zeCRT, zibakhuphela ngaphandle kwemarike. Singathini ngabo emva kweminyaka engaphezu kwamashumi amabini sihlala emakhayeni ethu? Oomabonakude be-LCD kunye neemonitha azilahleki ukuthandwa kwaye zisephezulu. Azikho izikrini zeplasma, okanye i-OLED esefashonini mva nje ezodlulayo. https://cxcvb.com/texnika/televizor/texnology/amoled-ili-ips-chto-luchshe.html Kwiminyaka edlulileyo, kuphela uhlobo lokukhanya kwe-matrix lutshintshile. Ngaphambili, izibane ezibandayo ze-cathode fluorescent (CCFL) zazisetyenziselwa ukuyikhanyisa, namhlanje zisetyenziselwa ngakumbi amandla ombane akhupha ukukhanya (LED). Ukujonga unikezelo lweevenkile ezikwi-intanethi, ngokuqinisekileyo uya kufumana igama elithi LED TV. Khumbula ukuba le yi-LED backlight LCD TV kwaye ayinanto yakwenza nobuchwephesha be-OLED.

1. I-LED ethe ngqo -i-diodes ibekwe phantsi kwe-matrix kwaye ihlale isebenza kuyo yonke imisebenzi ye-TV. Kwimeko yokukhanya okuthe ngqo, abavelisi bahlala besebenzisa into eyaziwa ngokuba yi-dimming yendawo ukufezekisa abamnyama abanzulu.
2. I-Edge LED – ii-LED zibekwe ecaleni kwe-matrix. Esi sisisombululo sokugcina amandla, kodwa njengoko uza kubona kamva, sikhokelela ekukhanyeni okungalinganiyo kwesikrini.

Indawo yee-LED inempembelelo enkulu kumgangatho womfanekiso. Kulo lonke inqaku, siya kuzama ukuxoxa nganye kwezi teknoloji ngokweenkcukacha kwaye sifumane impendulo kumbuzo we-Edge LED okanye i-LED eNgqongileyo.

I-LED ethe ngqo-i-dimming LED matrix yendawo ye-TV

Ukukhanya okuthe ngqo kwe-LED yendawo bubuchwephesha obuphambili obunikezela abamnyama abanzulu. Ngokusebenzisa ulawulo lwe-backlight, umfanekiso ufumana umgangatho ongafumanekiyo kwii-TV ze-DLED eziqhelekileyo. Umahluko ophezulu ufezekiswa. Iindawo ezikhanyayo ziyancipha ngokuzimeleyo, zishiya iindawo ezikhanyayo zibonakala ngokucacileyo. Le yeyona ndlela ilungileyo kwabo bafuna i-TV ye-LED kodwa abafuni ukujamelana nokungalunganga kwe-Direct or Edge. Kwiinkcukacha zeTV, unokufumana igama elithi Ukufiphala kweNdawo yeNdawo egcweleyo (i-Samsung isebenzisa igama elithi Direct Full Array), oku akuyonto ingaphaya kokukhanya ngasemva kunye neendawo. Zifakwe kwiiTV eziphakathi kunye neziphezulu. Kwiimodeli ezibiza kakhulu, uya kufumana ukuya kuthi ga kwiindawo ezili-1000, kwiindawo ezingabizi kakhulu, ngokuqhelekileyo kuphela i-50-60.

Izinto eziluncedo kunye nezingeloncedo zokukhanyisa ngokuthe ngqo

Ukukhanya okuqhelekileyo kwe-DLED-backlight kunezinto ezininzi ezingalunganga ngaphezu kokukhanya kwe-matrix. IiTV ezinobuchwephesha be-LED ngokuyintloko zineengxaki ezimnyama, ezithi kwizikrini zazo zihlala zithatha i-shades yegrey. Nangona kunjalo, i-LED eNgqongileyo ayimbi kangako xa idityaniswe nobumnyama bendawo. Iphelisa ininzi yeentsilelo zeteknoloji ephantsi. Imifanekiso ihlala iqaqambile kwaye iqaqambile, ngelixa izithunzi zithatha ubunzulu.

I-LED ethe ngqo okanye i-Edge ye-LED, yeyiphi i-backlight onokuyikhetha kwaye yeyiphi onokuthi wale: https://youtu.be/P0CCeS9R6yU

Edge LED – yintoni na?

KwiiTV ezinobuchwephesha be-Edge LED, iidiode ezimhlophe zangemuva zibekwe kuphela kwimida ye-matrix (kwiimodeli ezingabizi kakhulu, oku kunokuba ngumphetho omnye okanye emibini). Ukuze ukukhanya okuvela kwii-LED kufikelele kwiindawo ezikude kakhulu, imodyuli ye-LGP iyafuneka ukuyisasaza. Izikrini ze-LED ze-Backlit Edge zincinci kodwa zinemiba enokukhanya okufanayo. Umqolo omnye wee-LED akwanelanga ukukhanyisa kakuhle kwayo yonke imixholo yomboniso, kwaye imodyuli ekhethekileyo ayincedi kakhulu apha. Ngokuqhelekileyo, umfanekiso uya kuqaqamba emiphethweni kunasembindini. Ngexesha elifanayo, iindawo ezimnyama aziyi kuba mnyama njengoko kufuneka zibe. Nangona kunjalo, iiTV ze-Edge ze-LED zinomlinganiselo ongcono wokuchasana kuneeTV eziqhelekileyo ezikhanyisayo.

Izinto eziluncedo kunye nezingeloncedo zokukhanya komphetho

Ngenxa yenani eliphantsi lee-LED, ii-Edge LED TV zitshiphu ukuqhuba. Bachukumisa ubuncinci besikrini, esibukeka kakuhle ngaphakathi. I-Edge ye-LED ilinganiselwe xa kuziwa ekuveliseni umbala wendalo. Ukwenza izinto zibe mbi ngakumbi, i-Edge LED ayisiyiyo inketho ephantsi kakhulu kuba iteknoloji idinga imodyuli yokusabalalisa i-LGP.
