Sixela indlela yokukhetha ubungakanani besikrini esifanelekileyo kuxhomekeke kumgama ukuya kumbona, i-engile ebukekayo kunye nemvume.
Ukuba umfanekiso kwi-tv entsha ivuthelwa okanye ibonakale kakuhle, ityala alinakuba ngokupheleleyo kwi-Forfunction. Eyona nto inokwenzeka, impazamo yenziwe ekukhetheni ubungakanani besikrini. Thetha malunga nokubala i-tv diagonal ukonwabela ukujonga.
Yintoni ekufuneka uyithathele ingqalelo xa ubala i-tv diagonal
Kutheni le nto iparamester ibalulekileYeyiphi imigaqo yokubala
- Umgama oza kubambiza
- Jonga i-angle
- Ukubeka esweni isisombululo
Kutheni iMicimbi yeFomamial xa ukhetha
I-tvs yanamhlanje, ngaphandle kokuba inkangeleko kunye nokusebenza, yahlukile kwimicimbi yabo kwangaphambili ngento yokuba banokulungiswa kubo, kwaye oku kubalulekile ukuba bakhethe ubungakanani.
Enye yeempawu eziphambili zobugcisa zesixhobo lixabiso le-diagonal. Oku kubhekisa kumgama ukusuka kwikona enye yescreen ukuya kwenye, hayi kufutshane ne-engile. Kubalulekile ukuqwalasela ukuba isikrini silinganiswe. Ifakwe kwizindlu, ngoko ke imilinganiselo yezinto iyonke iya kuthi, ngokuzenzekelayo. Abanye badidanisa iikhonsepthi ezimbini kwaye, bechaza ukuba ukhetha ntoni umabonwakude, gxila kubungakanani besikrini njengobukhulu besixhobo. Ukuba kuyenziwa ukufaka izixhobo kwi-niche okanye ifenitshala, unokukwenza kwaye isixhobo asiyi kufika apho.
Kwiimpawu zobugcisa zezixhobo, le parameter iboniswe kwi-intshi. Ukufumana iisentimitha eziqhelekileyo, kwanele ukuphindaphinda le nombolo ngo-2,54.
Yeyiphi imigaqo yokubala
1. Khetha i-diagonal yeTV kuxhomekeka kumgama uye kwiscreen
Kuya kufuneka uqale ukhetho lwemodeli ukususela ekuchongeni indawo yokufaka, iya kucaca ekubonakalisweni kwesixhobo esiya kubonakala. Emva kokuba ubala kude kubaphulaphuli.Ngokutsho kwendlela efunyenweyo yokubala, i-Diagonal yaphinda ilungele ukulingana 3 okanye 4, ifanelekile ukufumana izixhobo nge-Kinescope, emva koko kwafuneka ukuba uthathele ingqalelo inqanaba lemitha, imvume kunye nefomathi yomfanekiso.
Umsebenzi we-TV wanamhlanje, zikhuselekile, zinenkcazo ephezulu. Iskimu esitsha ithathela ingqalelo iiparamitha izixhobo ezakhiweyo zeMatrix.
I-Counterication ibanga yeTV yanamhlanje:
- Ye-HD elungile - 2.3.
- Ye-HD-1.56.
- Kwi-Ultra HD - 0.7.
Kukho omnye umthetho. Esi sixhobo singaphezulu, kokukhona kuya kuba ngumgama ukuya kumbukeli, kwaye ivolumu yegumbi kufuneka ilingane. Ke, kwigumbi lokuhlala elichiza, akufuneki ufake iliso elincinci. Ngaphandle koko, kuya kufuneka uyeke kuyo, uzama ukuqwalasela lo mfanekiso. Ilungile kwaye ibuyise umva: Khetha isixhobo esikhulu kwigumbi elincinci elingafanelekanga. Nokuba ingayi kufuna njani.
Iskimu sokubala kuxhomekeka kwindawo yegumbi
- Amagumbi kwiimitha ezili-12. M kwaye ngaphantsi kokukhetha izikrini ezingama-20 ze-intshi.
- Kwizakhiwo ze-12-18 yeemitha. Izixhobo ze-5-37-i-intshi zifanelekile.
- Amagumbi e-20 yeemitha. M kunye nokukhetha izixhobo ezivela kwii-intshi ezingama-40.
| I-diagonal, i-intshi | Umgama osuka kumbonisi kwiscreen, iimitha |
|---|---|
| 17. | Nye |
| 25. | 2. |
| 32. | 2.5 |
| 37. | 2.7 |
| 40. | 3. |
| Amashumi amahlanu | ezine |
| 65. | 4.5 |
| 70. | Ntlanu |
| I-80. | 6. |
2. Jonga i-angle
Lo mzuzu uhlala ungagxininisi. Nangona kunjalo, umyinge ofanelekileyo we-engile yokujonga, isisombululo kunye nobungakanani besixhobo senza ukuba sifumane ifuthe lobukho. Ke, ukuyonwabela ngokupheleleyo imuvi oyithandayo okanye ugqithiso. Iziphumo zobukho zichaphazela umbono wecala, edityaniswe kuphela kwii-angles ezithile zoqwalaselo. Ke ngoko, kubaluleke kakhulu ukubeka iliso ngokuchanekileyo.
Iingcebiso zobalo
- Ukuba i-angle i-ongle i-20 °, umbukeli kufuneka asuswe kumgama olingana neleyibheli kwi-intshi kwi-intshi ezindathulwe ngu-2,5.
- I-angle ye-30 °, ukulingana kwe-1.6 ikhethiwe.
- I-angle ye-40 ° I-COOONONY- 1.2.
Mhlawumbi izixhobo ezibekwe kwindawo okanye kwitafile kunzima ukukhetha i-engile yokujonga. Kodwa kwiiphaneli ezilungisa eludongeni, kulula kakhulu ukuyikhetha. Ukulungelelanisa ukuphakama kokudibanisa, unokukhetha isisombululo esifanelekileyo.
3. Isisombululo seTV
Umgangatho womfanekiso ovela kwiTV eyahlukileyo yahlukile. Kuxhomekeka kwimvume. Kuyaziwa ukuba umfanekiso osikrini wenziwa ngamanqaku amancinci, babizwa ngokuba ziiPixel. Isisombululo linani la manqaku kumboniso. Kunokuba kunjalo, umfanekiso ocacileyo. Ingajongwa, ihlale ikufutshane nephaneli yeTV. Kwelinye icala, ukuba kukho iipikseli ezincinci, kufuneka uhlukane. Ngaphandle koko, lo mfanekiso uya kuba yinto engathandekiyo "ekuhambeni."Kwiimodeli ezimbini ezifanayo zinokwahluka. Ngokufanelekileyo, kuyayimfuneko ukubeka egumbini.
Iimvume zezona fom zeZixhobo ezithandwayo
- I-HD ilungele - 1366x720
- I-HD-1920X1080
- I-Ultra HD-ukusuka kwi-3840x2160.
Ke, ukunikwa umgangatho womfanekiso, unokuhlengahlengisa umgama ukusuka emehlweni ukuya kwiTV. Ukuphakama kwesisombululo, umntu unokungabi ngaphantsi. Amaxabiso acetyiswa ngasentla unokutshintshwa kuthathelwa ingqalelo iimpawu zemodeli ekhethiweyo.
Ukuziphakamisa, indlela yokukhetha i-TV yeTV yeTV, kuyafuneka ukongeza ukuba kukho umahluko omncinci phakathi kokuboniswa kwekristali kunye neplasma. Ubungakanani be-pixel yokugqibela bungakumbi. Kuyavela ukuba ngobukhulu obufanayo kunye nesisombululo, umfanekiso uyahlukahluka. Ke ngoko, kuyavakala ukubeka iplasma kancinci ngakumbi kunemodeli yekristale yolwelo efana nayo kuzo zonke iiparamitha zobugcisa.
