Kulezi zinsuku lapho siyothenga ithelevishini bese siqala ukubheka onobuhle online noma ngokuya enxanxatheleni yezitolo, singena ezweni lapho uma singenalo ulwazi, singazilahlekisela. Lokhu kungenxa yokuthi abakhiqizi bakhipha amamodeli amaningi ahlukahlukene, besebenzisa ubuchwepheshe obuhlukahlukene ngokuya ngobubanzi noma injongo eyenzelwe imodeli. Singazithola sisuka ku-LCD siye ku-OLED nge-QLED noma nge-LED.
Yingakho singalahleka futhi uma singaziswanga sisezandleni zomthengisi osemsebenzini noma imibono esiyithola ku-intanethi. Singathatheka futhi ngeseluleko somngane we-geek esinaye. Yize ngaphandle wonke amathelevishini engabonakala efana, kunomehluko omkhulu phakathi kwabo ngokuya ngobuchwepheshe babo kanye nokwakhiwa kwephaneli. Kulesi sihloko sizobonisa ukuthi yini umehluko omkhulu phakathi kwe-LED ne-LCD ejwayelekile.
Yini i-LCD?
Ukuholelwa yiphaneli eyenziwe nge-crystal liquid njengoba amagama ayo akhombisa. Isibonisi se-Liquid Crystal, ubuchwepheshe obudala kakhulu namuhla obuqhubeka nokunikeza imiphumela emihle ngokobunjani nokuthembeka. Lawa mapaneli enziwe ngamaphikseli amaningi akhiwa ngamamolekyu e-liquid crystal aqukethwe phakathi kwama-electrode asobala. Amakristalu oketshezi asabela ngezindlela ezingalindeleka lapho ubukhulu benkokhiso kagesi buguquka. Lokhu kubangela ukuthi amakristalu aguquke futhi anyakaze, akhe lokho esikubona kamuva esikrinini, ngemibala namalambu.
Yini i-LED?
Amapaneli e-LED empeleni ayihlobo lwe-LCD okuwukuvela kobuchwepheshe obusetshenziswa izikrini ze-LCD ezindala. Ubuchwepheshe be-LED buthatha isikhundla samaphayiphu we-backlight fluorescent wepaneli nge-LED technology light emitting diode. Lokhu kuholela ezingeni eliphakeme lobumnyama nokuqhathanisa uma kuqhathaniswa nobuchwepheshe bangaphambilini be-LCD, ngaphezu kwe- ukunemba kombala okungcono kuqhathaniswa. Ngaphandle kokukhohlwa okuthinta ukwakheka, ukusuka kumapaneli e-LCD amakhulu kufanele ubeke amashubhu we-fluorescent, uma kuqhathaniswa nama-diode amancane nezincane, okwenza amathelevishini abe nesitayela futhi abe mncane kakhulu.
Izinzuzo nezinkinga phakathi kwama-LED uma kuqhathaniswa ne-LCD
I-PROS
- Ukuboniswa kwe-LED impela kukhanye ukwazi ukufinyelela kuma-bits angama-3000 wokukhanya okwenza umehluko ngaphandle.
- Una impilo eshalofini endeEziningi zazo zingafinyelela ngaphezu kwamahora angama-50.000 wokubuka.
- Zikhiqiza ukushisa okuncane kakhulu ngakho futhi kusebenza kahle ukwehlisa ukusetshenziswa kakhulu.
- Idizayini enesitayela okufanele ibe yiyo mncane, okwenza kube nemiklamo ebukeka njengemidwebo esodongeni lwethu.
CONS
- Kungumsebenzi wobuchwepheshe ibiza kakhulu.
- Su ukukhanda kuyinkimbinkimbi ngokwengeziwe ngoba ama-diode athengiswa epuletini.
- La Isixazululo siphansi kancane.
- Ngenxa yakhe ukukhanda okubizayo ezimweni eziningi kungcono ukuthenga ithelevishini entsha.
Ngithenga yiphi i-TV?
Okokuqala, kufanele sazi ukuthi sifuna ukuyisebenzisela ini ithelevishini, ngoba njengamanje i-LED ibaluleke kakhulu emakethe ngokwezikrini ezisezingeni eliphakeme nezingazweli. Ezikhaleni ezingaphandle, lapho ukukhanya kushaya khona ngamandla amakhulu, Kunconywa ukuthi uhlale ukhetha iphaneli enhle ye-LED enezinombolo zokukhanya ezingekho ngaphansi kuka-1000. Kepha uma sizosebenzisa ithelevishini yethu kuphela endlini, esikhaleni esinokukhanyisa okuphansi, i-LCD ingaba yindlela engcono kakhulu ngenxa yesinqumo sayo esingcono futhi ngaphezu kwakho konke ukumelana kwayo nokukhululeka kokulungiswa. Uma sihlose ukuba nethelevishini iminyaka eminingi, lokhu kungabalulekile.
Ukudlala
Kumageyimu evidiyo, okuhle yiphaneli enama-lag wokufaka okungenani kungenzeka futhi lokhu kuvame kakhulu kumapaneli e-LCD, futhi nasekudutshulweni kwemidlalo yevidiyo, lapho sisebenzisa khona ama-snipers, isixazululo singaba ukhiye, ngoba okungahle kubonakale njengamaphikseli, empeleni kuyisitha esikhomba kithi. Uma ngakolunye uhlangothi, igumbi lethu lapho sidlala khona likhanya kakhulu futhi sithanda ukudlala ngokusobala, ukukhetha okuhle kakhulu kungaba yi-IPS LED ngoba inokukhanya okungcono nama-engeli wokubuka.
Njengamanje kuvamile kakhulu ukuthi imidlalo ehlukahlukene ikunikeze Linganisa i-HDR ngokuthanda kwakho, ngakho-ke uma singathola ithelevishini ngalobu buchwepheshe, kuzothokozelwa ezimeni lapho ukukhanya okukhanyayo okuphezulu kuqhubeka khona njalo, njengemidlalo yevidiyo ethusayo noma imidlalo yomhlaba evulekile engaphandle.
Ukubona ama-movie
Ukubona ama-movie Ngaphandle kokungabaza, ubuchwepheshe be-LED yibo obunconywa kakhulu, ikakhulukazi ubuchwepheshe be-EDGE LED obusetshenziswa kakhulu yiSamsung kumaphaneli ayo agobile., ubuchwepheshe obuthola abamnyama abamsulwa ngokucisha izindawo zikamabonakude lapho omnyama emsulwa, ngaleyo ndlela kulinganiswa iphaneli ye-OLED lapho omnyama emsulwa ngokuphelele.
Iphaneli lizoba ngelohlobo lwe-VA, iphaneli elifinyelela imibala ecacile nokuqhathanisa okuhle, elingafinyeleli ezingeni le-OLED kodwa kuphumelela kakhulu. Ngokukhethekile, amaphaneli agobile e-high-end Samsung afinyelela lokho ngenxa yamajika ayo nokubhinca kwephaneli yayo, ukubonakaliswa akubonakali. Okuwukuphela kokwehla kwalobu buchwepheshe i-engeli yokubuka ephansi nezindleko eziphakeme, ngaphezu kokulungiswa kwayo okubizayo uma kungenzeka kwehle.
Kwezamabhizinisi nokwamukela izihambi
Uma lokho esikudingayo kungumabonakude olenga ebhizinisini lethu noma endaweni yokucima ukoma, ngaphandle kokungabaza ubuchwepheshe obufanele kakhulu yi I-LED, ikakhulukazi ubuchwepheshe be-IPS, ubuchwepheshe obusinikeza ezinye ama-engeli wokubuka abanzi kakhulu, ezonikeza umbono ongcono kuwo wonke umphakathi nomaphi lapho itholakala khona. Ngaphezu kwalokho, lobu buchwepheshe bunokukhanya okuphezulu okuphezulu ukuze ukukhanya okukhanyayo kunganciphisi ikhwalithi yesiboniso.
I-IPS ingenye yezobuchwepheshe ezisetshenziswa kakhulu kumapaneli e-LED futhi ingenye yezishibhile. I-LG inezinhlobo ze-IPS ezihamba phambili emakethe, ngakho-ke uma sisesha ikhathalogi yayo singathola izibonelo ezinhle kakhulu zalobu buchwepheshe be-LED.
