Naphezu kokuzikhethela okukhulu kwezokuzijabulisa ngendlela enambitheka ngayo nangesikhwama esikhwameni, isikhathi esiningi isikrini sethelevishini sihlale sisona esingcono kakhulu sokudlula kusihlwa. Ngenxa yalesi sizathu, umbuzo othi "Ungakhetha kanjani i-diagonal ye-TV?" Awulahlekelwa ukuhambisana kwawo.
Yimaphi ama-diagonal enza ama-TV?
Ukudayela kwanoma yisiphi isikrini noma ukubonisa (ithelevishini noma ikhompyutha) ibanga eliphakathi kwamakhonksi amabili ahlukene, isibonelo, ngezansi kwesokunxele nangaphezulu kwesokudla. Ngokwesiko kulinganiswa ngamasentimitha. Ukuze uhumushe inani kumamentimitha ajwayelekile ajwayelekile kubantu bakithi, yande nge 2.54. Izinga legolide lezikrini zethelevishini kufaka phakathi amamodeli 19, 22, 26, 32, 37, 40, 42, 46, 47, 50, 55, amasentimitha angu-55. Izikrini ezinezinhlamvu ezingu-15, 16, 23, 24, 39, 43, 51, 52, 58 no-inches ngaphezulu azivami kakhulu.
Izingxenye zesikrini sethelevishini zingaxhunyaniswa komunye nomunye ngesilinganiso se-4: 3 noma se-16: 9. Lokhu kusho ukuthi amadivaysi amabili anama-diagonal alinganayo angaba nobukhulu obukhulu ngokuphelele nokubukeka. Kuyafaneleka ukucabangela, ukuhlose ukuvuselela le nqubo. Manje izinga elijwayelekile le-4: 3 liyinto eyedlule, inika indlela eya ngokukhethekile ekubukeni ama-movie angama-screen standard ejwayelekile 16: 9. Ukuze unqume ukuthi yi-diagonal enhle ye-TV yesimo ngasinye esithile, udinga ukwakha kumingcele elandelayo:
- ubukhulu bekamelo lapho lizofakwa khona - isikrini esikhulu ekamelweni elincane alithathi nje kuphela isabelo sebhubesi, kodwa futhi akukhathazi ekubukeni;
- uhlobo lwe-matrix yokubonisa (i-LCD, i-PDP, i-OLED) - ngezilinganiso ezifanayo, i-OLED-matrix izonikeza isithombe esingcono kune-plasma (PDP) noma i-LCD;
- ukulungiswa kwesikrini - uma kunjalo, okucacile nokugcwele isithombe kuzoba;
- ikhwalithi (isinqumo) sesignali.
Yimuphi i-TV ehambisanayo yokukhetha?
Ukuxazulula umbuzo wokuthi ungakhetha kanjani i-diagonal ye-TV kuyingozi enkulu ukuthatha indlela "ngcono nakakhulu." Kodwa ngisho noma izimali zivuma, ukuthenga i-TV enkulu yamasentimitha angu-50 egumbini elincane lokuhlala ukuze ubuke izindaba kulo akuyona into engcono kakhulu. Ukuthakazelisa ekuthengeni kuyobe kungonakaliswa ngethemba esithombeni esihlukana ngezikwele ngasinye-amaphikseli.
Kukhona isincomo esihlolwe isikhathi esithile sokuthi ungakhetha kahle kanjani ukudayela kwe-TV ekamelweni: ubungakanani bayo kufanele bulingane nokunciphisa kathathu ibanga ezilalelini. Le mithetho iyakwazi ukufakazela izimpawu zezinga elijwayelekile (ukuxazulula): ukusakaza emoyeni, ithelevishini, i-DVD ne-VHS. Uma i-TV inamandla okudlala imifudlana yekhwalithi ephakeme (i-Full HD, i-Blu-Ray, i- 4K ), ibanga elisehlweni lingancishiswa futhi ukukhula kwe-diagonal kwande. Usayizi walo kulokhu kubalwa njengesiqingatha ibanga lababukeli.
Ungakhetha kanjani i-diagonal ye-TV egumbini lokuphumula?
Cabanga ngesibonelo sokuthi ungakhetha kanjani i-diagonal ye-TV kude. Ake sithi leli sofa livela endaweni lapho i-TV ihlelwe khona ukuthi ibekwe ngamamitha angu-2. Ukuhlukanisa ngo-3 sithola ubukhulu be-diagonal, obulingana no-0,66 wamamitha noma ama-25,98 amayintshi. Uma ukhetha idivayisi esekela i-Full HD format, kunconywa ukuthi usebenzise ifomula elandelayo: i-diagonal (in intshi) ilingana nebanga kumbukeli (ngamamitha) wanda ngamashumi amabili. Futhi ngaphambi kokuma amamitha amabili ukusuka odongeni, ungafaka isikrini nge-diagonal of 50 amasentimitha.
Ngaphambi kokugcina ukhetha ukudibanisa kwe-TV kunenzuzo yokwenza "i-test drive" encane, uzama ukubuka amavidiyo amaningana emadolobheni ahlukene kuwo. Ngisho nosayizi wesibuko okhethwe kuzo zonke izincomo kungabangela ukungakhululeki ngenkathi kubukela ama-movie. Igolide elisho izindlu eziningi zokuhlala ezinkampanini ezincane zingabizwa ngokuthi ama-TV, ahlukene ngamasentimitha angu-32 noma angu-81 cm.
Yimuphi i-TV ehambisanayo yokukhetha ekamelweni?
Labo abakhetha ukubuka imibukiso ye-TV namabhayisikobho alele embhedeni, kufanelekile ukunaka imodeli yamadivaysi ane-diagonal kusuka ku-22 kuya kuma-intshi angu-32. Izincomo zendlela yokukhetha kahle ukudibanisa kwe-TV ekamelweni lokulala, ngeke zihluke kakhulu ekamelweni lokuphumula: konke kuxhomeke ekunqumweni nasekuhloleni uhlobo lwe-matrix, ikhwalithi yesignali engenayo kanye nebanga kusuka esikrinini kuya kwamehlo.
Yimuphi i-TV ehambisanayo yokukhetha ikhishi?
Ukubuka i- TV ukufakwa ekhishini , kuzomele ukhumbule ukuthi lokhu kuyindawo enesimo esiyingozi - umswakama ophezulu kanye nokushisa kwamazinga okushisa akufakelani nesevisi ende ye-elekthronikhi. Ngakho-ke, lo mgodi kufanele uvikele kakhulu ngangokunokwenzeka kusuka ukuphazamiseka ngengozi yamanzi nogesi. Ukukhetha ukuthi iyiphi i-diagonal TV efanelekayo ekhishini, kungcono ukhethe usayizi wezithombe kusuka kumasentimitha angu-16 kuya kwangu-26:
- I-mini-ikhishi kuze kufike ku-9 m 2 kuyoba nekrini elanele elinama-intshi angu-16 kuya kwangu-19;
- ekhishini, indawo yayo eyi-10-15 m 2 ifakwe i-TV enesibuko esingu-22-26 amayintshi;
- Ukukhethwa kwe-diagonal yekhishi elikhulu kanye ne- studio izindlu kwenzeka ngokuvumelana nemithetho ejwayelekile.
