Sikhuluma ukuthi ungakhetha kanjani usayizi ofanele wesikrini ngokuya ngebanga lesibukeli, i-angle yokubuka nemvume.
Uma isithombe ku-TV esisha sishaywa noma sibonakale kahle, icala alikwazi ukuba semthethweni ngokuphelele. Ngokunokwenzeka, kwenziwa iphutha ekukhetheni osayizi besikrini. Khuluma ngokuthi ungabala kanjani i-TV Diagonal ukujabulela ukubuka.
Okufanele ubhekwe lapho kubalwa i-TV diagonal
Kungani i-Parameter ibalulekileNgaziphi izindlela zokubala
- Ibanga lokubukwa
- Bheka i-angle
- Ukuqapha Isixazululo
Kungani kunezindaba ze-diagonal lapho ukhetha
Ama-TV anamuhla, ngaphandle kokubukeka futhi asebenze, ahlukahluka kubanduleli babo ngeqiniso lokuthi bangalungiswa kubo, futhi kulokhu kubalulekile ukukhetha ocinayo.
Enye yezimpawu zobuchwepheshe eziphambili zedivayisi yinani le-diagonal. Lokhu kusho ibanga ukusuka kwelinye ekhoneni lesikrini kuya kwelinye, hhayi eliseduze kwe-angle. Kubalulekile ukubheka ukuthi lesi sikrini silinganiswa. Ifakwe ezindlini, ngakho-ke ubukhulu bemishini buzoba, ngokulandelana, ngaphezulu. Abanye badideka imiqondo emibili futhi, echaza ukuthi yini ukukhetha i-TV diagonal, gxila kusayizi wesibuko njengobukhulu bedivayisi. Uma kufanelekile ukufaka imishini kwi-niche noma ifenisha, ungayenza futhi idivaysi ngeke ifike lapho.
Ezimfanelweni zobuchwepheshe zemishini, le pharamitha ikhonjiswa kumayintshi. Ukuthola amasentimitha ajwayelekile, kwanele ukwandisa le nombolo ngo-2,54.
Ngaziphi izindlela zokubala
1. Khetha i-diagonal ye-TV ngokuya ngebanga esikrinini
Udinga ukuqala ukukhethwa kwemodeli ekutholeni indawo yokufaka, kuzocacisa lapho idivaysi izobonakala khona. Ngemuva kokudinga ukubala ukuvela kwezithameli.Ngokwendlela esepheliwe yokubalwa, i-diagonal yaphindwa yi-coefficing 3 noma i-4, ibifanele imishini nge-kinescope, khona-ke kwakudingeka ukuthi ibhekane nezinga lemisebe yedivayisi, imvume nefomethi yayo.
Ama-TV anamuhla asebenza kwezinye izimiso, aphephile ngokuphelele, anencazelo ephezulu. Uhlelo olusha lubheka amapharamitha wemishini eyakhelwe ngaphakathi matrix.
Isilinganiso sokubalwa esinconyiwe se-TV sanamuhla:
- Nge-HD Ready - 2.3.
- Kwa-HD Ful - 1.56.
- I-Ultra HD - 0.7.
Kunomthetho. Le divayisi ingaphezulu, okuthe xaxa kufanele kube yibanga kumbukeli, kanye nevolumu yegumbi futhi kufanele lilifanisa. Ngakho-ke, egumbini lokuphumula elibanzi, akufanele ufake ukuqapha okuncane. Ngaphandle kwalokho, kuzofanela ubheke kulo, uzama ukucubungula isithombe. I-Fair futhi ibuyise emuva: Khetha idivaysi enkulu egumbini elincane elingalungile. Akunandaba ukuthi bekungeke kufune kanjani.
Isikimu sokubala ngokuya ngendawo yegumbi
- Amakamelo kumamitha-skwele ayi-12. M futhi ngaphansi khetha izikrini ezingama-20-intshi.
- Ezakhiweni zamamitha-skwele ayi-12-18. Amadivayisi we-M 5-37-intshi afanelekile.
- Amakamelo amamitha-skwele angama-20. M futhi ngaphezulu kokukhetha imishini kusuka kuma-intshi angama-40.
| Diagonal, amayintshi | Ibanga kusuka kwesibukeli kuya kusikrini, amamitha |
|---|---|
| 17. | okukodwa |
| 25. | 2. |
| 32. | 2,5 |
| 37. | I-2.7 |
| 40. | 3. |
| amashumi amahlanu | okune |
| 65. | 4.5 |
| 70. | isihlanu |
| 80. | 6. |
2. Bheka i-Angle
Lo mzuzu uvame ukungagxili. Kodwa-ke, isilinganiso esinekhono se-angle yokubuka, ukulungiswa nosayizi wedivayisi kwenza sikwazi ukuthola umphumela wokuba khona. Ngakho-ke, ukujabulela ngokuphelele i-movie yakho oyithandayo noma ukudlulisa. Umphumela wokuba khona uthinta umbono ophelele, oxhumeke kuphela kuma-engeli athile wokubuyekezwa. Ngakho-ke, kubaluleke kakhulu ukubeka ukuqapha kahle.
Iziphakamiso zokubalwa
- Uma i-angle yokubuka ingu-20 °, isibukeli kufanele sisuswe ebangeni elilingana nokulebula kuma-inches manda ngama-2,5.
- Nge-angle ka-30 °, kukhethwe i-1.6.
- Nge-angle ye-40 ° coeffleflentle - 1.2.
Mhlawumbe imishini ebekwe esiteshini noma etafuleni kunzima ukukhetha i-angle yokubuka. Kepha ngamaphaneli elungisa odongeni, kulula kakhulu ukuyikhetha. Ukulungisa ukuphakama kokuhlanganisa, ungakhetha ikhambi elifanele.
3. Ukulungiswa kwe-TV
Ikhwalithi yesithombe evela ku-TV ehlukile yehlukile. Kuya ngemvume. Kuyaziwa ukuthi isithombe esikrinini sakhiwa ngamaphuzu amancane, abizwa ngamaphikseli. Isixazululo yinombolo yamaphuzu anjalo esibonisweni. Kunabo bangokwengeziwe, isithombe esicacile. Ingabukwa, ngisho nokuhlala eduze nephaneli ye-TV. Ngakolunye uhlangothi, uma kunamaphikseli amancane, udinga ukusuka kude. Ngaphandle kwalokho, isithombe sizoba esingemnandi 'sesikebhe.'Kumamodeli amabili afanayo ngosayizi angahluka. Ngakho-ke, kuyadingeka futhi ukuyibeka egumbini futhi.
Izimvume zefomethi yensimbi ethandwa kakhulu
- HD Ready - 1366x720
- HD Ful - 1920x1080
- Ultra HD - kusuka ku-3840x2160.
Ngakho-ke, unikezwe ikhwalithi yesithombe, ungaguqula ibanga ukusuka emehlweni kuya ku-TV. Lapho kuphakama isinqumo, umuntu angaba ngaphansi. Amanani anconyelwe ngenhla angaguqulwa aguqulwe acatshangelwe izici zemodeli ekhethiwe.
Kuzincomo, ukuthi ungayikhetha kanjani i-TV diagonally, kuyadingeka ukwengeza ukuthi kunomehluko omncane phakathi kwekristali ye-liquid crystal kanye ne-plasma ekhombisa. Usayizi wokugcina we-pixel ungenye. Kuvela ukuthi ngosayizi kanye nesinqumo esifanayo, isithombe sizohluka. Ngakho-ke, kunengqondo ukubeka i-plasma ngaphezulu kwemodeli yekristalu ewuketshezi efanayo kuwo wonke amapharamitha wezobuchwepheshe.
