Ni ikihe gipimo cyo kugarura ecran ya TV kandi nikihe cyiza?

Ibipimo nkibipimo byo kugarura ecran ya TV birahinduka kubantu bashaka gukoresha ikoranabuhanga neza mumaso yabo kandi bakakira ishusho nziza. Gukuramo inshuro nyinshi (hertz) byerekanwe mumabwiriza ya TV cyangwa monitor iyo ari yo yose, kuko igena niba bizaba byiza gukora cyangwa kureba gahunda igihe kirekire. Kugirango uhitemo neza, birasabwa kwiga witonze ibiranga byose, gukora igereranya na hertz. Ibi bizagufasha kumva icyerekezo cyiza kubakoresha runaka.

Ni ubuhe buryo bwo guhanagura, ibyo tuvuga, ni ubuhe bwoko bwa hertz bukoreshwa muri TV

Mbere yo gucengera mubiranga igitekerezo, ugomba kwihitiramo ubwawe igipimo cyo kugarura ecran icyo aricyo, icyo kigira, impamvu cyitabwaho nababikora. Buri ruganda, ufata inzira ishinzwe kubikorwa byabo, yerekana ibipimo bigezweho kubikoresho, mumabwiriza cyangwa kubipakira. Ibiciro bisabwa cyane ni:

• 60 Hz.
• 120 na 100 Hz.
• 240 Hz.

Indorerezi zigezweho na TV nabyo bifite amahitamo angana na 480 Hz. Ni ngombwa kubanza gusobanura icyo hertz iri muri TV nicyo kigena igipimo cyo kugarura ubuyanja. Mu magambo yoroshye, iyi numubare runaka inshuro kumasegonda mugihe ishusho ivugururwa kuri ecran ya TV cyangwa monitor ya mudasobwa. Urugero, iyo 60 Hz yatangajwe, noneho ishusho (ishusho umuntu abona) ivugururwa inshuro 60 kumasegonda. Ni ngombwa gusobanukirwa ko uko igipimo cyo kugarura ubuyanja, ishusho izaba nziza, kandi bizagenda byoroha. Kubijyanye na TV, guhitamo bitangwa muburyo bukurikira:

1. Ikoranabuhanga rya LCD niterambere ryambere ryatangijwe kuri LCD TV na monitor. Gukora amashusho muriki kibazo bikorwa hakoreshejwe urumuri rwihariye rwa fluorescent, rwagenwe nka CCFL. Ibikoresho nkibi birashobora gutanga impuzandengo yubuziranenge. Mugihe uhisemo matrix, ugomba kuzirikana ko kugirango wirinde guhindagurika, ugomba guhitamo TV ifite Hz 100 kandi irenga.
2. LED  ni tekinoroji ya LCD. Televiziyo na monitori muriki kibazo byunganirwa na sisitemu nshya yo kumurika amashusho ukoresheje diode yizewe kandi ifatika. Bafite itandukaniro ryinshi. Birakenewe kwitondera ko gushyira diode hejuru ya ecran bishobora kuba bitandukanye. Ibi bigena ireme ryanyuma. Yanditse ku bikoresho nka “LED Yuzuye”, “LED nyayo” cyangwa “LED itaziguye”. Muri iki kibazo, itara ryinyuma rizagabanywa kuringaniza igice cyose cya ecran cyangwa monitor. Niba “Edge LED” yerekanwe, noneho bivuze ko diode iherereye mubice byanyuma. Ubwiza bwibishusho bwiza muriki kibazo bizerekana TV 50 Hz cyangwa 60 Hz.
3. Plasma panel – kumashusho yo murwego rwohejuru, ntigikenera kumurikirwa byongeye, kubera ko selile zimurikirwa nimirasire ya ultraviolet igwa kuri fosifore. Plasma itanga itandukaniro ryinshi kandi ryimbitse, ryijimye cyane. Tugomba kuzirikana ko nyuma yimyaka mike, plasma selile zitangira kwaka buhoro buhoro, bigira ingaruka mbi kumiterere yishusho.
4. OLED ni tekinoroji igezweho yerekana ubwiza bw’amashusho, amabara yimbitse kandi akungahaye, hamwe n’ibicucu bitandukanye. TV zigoramye 200Hz, pannea ultra-thin, moderi nini yimikino yo murugo, byose muriki gihe bizaguha ihumure mugihe ureba TV cyangwa ukora kuri mudasobwa.

Igipimo cyo kugarura ecran ya TV ni 120 cyangwa 60 Hz kuri TV, ugereranije TV mumashusho afite imbaraga hamwe nibiciro bitandukanye: https://youtu.be/R86dWrDnulg frame 50 kumasegonda. Gutunganya amashusho ya digitale byatumye bishoboka kwigana buri kintu nkiki kandi ukabigaragaza kabiri. Ukoresheje ubu buryo, byashobokaga guteza imbere TV ya hertz 100. Tekinoroji yakoreshejwe muri yo yemereye gukuraho flicker, ituma ishusho yoroshye kandi ikanezeza ijisho. Gushushanya amakadiri yinyongera kugirango ukore ishusho yuzuye ishingiye ku isesengura ryibihe byashize, byemeza neza neza ishusho yerekanwe kuri ecran. Ibintu bigenda kumuvuduko mwinshi, kurugero, bizakara kandi ntibisobanutse muriki kibazo.

Niki kigira ingaruka kuri hertz muri TV

Nibyiza kandi kumenya icyo igipimo cyo kugarura ecran ya TV yawe kigira ingaruka. Kugirango ukore ibi, ugomba kumva uburyo inzira yo gufata amashusho iba. Ifata igikorwa cyihariye kibaho mugihe runaka mugihe. Igisubizo ni amashusho menshi aracyariho, bita amakadiri. Nyuma yo kubegera, urashobora kureba muburyo bukomeza kugenda. Mubihe byinshi, ibipimo byerekana ibipimo bisa (ibiganiro bya tereviziyo ya tereviziyo) bishingiye ku nshuro z’amashanyarazi yatanzwe. Niyo mpamvu ibipimo fatizo bitandukanye muri Amerika, Uburusiya cyangwa Uburayi. Ku bikoresho bimwe hariho PAL cyangwa NTSC, kuri VCPs yakozwe mumyaka mirongo ishize, ibi ntakindi kirenze uturere ubwo buhanga bushobora gukorera byuzuye. Kurugero, PAL zirimo Ubwongereza hamwe nu Burayi bwinshi. Ngaho igipimo cyikadiri kizaba 25 fps. Uturere twa NTSC bivuga Amerika. Hano inshuro zimaze kuba 30 frame kumasegonda.
Niba videwo yanditswe kuri firime isanzwe (ntabwo ari digitifike), noneho amakadiri 24 gusa niyo azanyura kumasegonda. Guhuza amashusho asa nubusanzwe bikorwa kugirango ubungabunge umurongo wakoreshejwe. Ibi birakenewe, kurugero, mugihe cyo gutangaza gahunda. Mugihe ishusho yimuriwe kuri ecran ya TV, igikoresho kizakina amakadiri muburyo bukwiye. Biragaragara ko inshuro za videwo zahujwe mu turere twa PAL ari 50 Hz, naho mu turere twa NTSC ni 60 Hz. Igipimo cyo kugarura ecran ya TV kigira ingaruka kumashusho no kubura flicker.

Ni ngombwa kuzirikana ko iterambere rihoraho ryikoranabuhanga, iterambere ryabo nyuma biganisha ku kuba imiterere mishya yakira ishusho isobanutse kandi karemano.

Igipimo cyo kugarura ubuyanja kigira ingaruka kumikorere?

Ntugomba kumenya gusa igipimo cyo kugarura ubuyanja bwa TV icyo aricyo, ahubwo ugomba kumenya ninshingano zikoranabuhanga. Kubura flicker bigira ingaruka nziza kubuzima bwamaso. Iyo ureba porogaramu cyangwa firime igihe kirekire, ukina kuri mudasobwa cyangwa ukora ukoresheje moniteur, nibyiza guhitamo uburyo bwibikoresho aho byatangarijwe munsi ya Hz 100. Imikorere mubijyanye na tekinike nziza ntabwo ihindurwa nigipimo cyo kugarura ecran. Iri koranabuhanga rifitanye isano itaziguye nibice bigaragara hamwe nubwiza bwishusho. Kubwibyo, igisubizo cyikibazo cyo kumenya niba monitor hertz igira ingaruka kumikorere ya mudasobwa oya, ariko kubijyanye nubwiza bwibishusho n’umutekano w’amaso, yego.

Nibihe byerekana ecran ya TV nibyiza kumaso

Iyo uhisemo TV, igipimo cyo kugarura ubuyanja kiba kimwe mubintu byingenzi byerekana ubuziranenge bwacyo, ubwizerwe, ibigezweho kandi bikwiriye gukoreshwa igihe kirekire. Mbere yo kugura, birasabwa guhitamo imirimo ukeneye TV cyangwa monitor. Niba umurimo wingenzi ari ukureba imiyoboro ya tereviziyo ya digitale cyangwa insinga, firime zifite ubuziranenge bwa HD, noneho bizaba bihagije kugirango umukoresha usanzwe agure moderi ifite 60 Hz. Muri iki kibazo, umuntu ntazabona itandukaniro rinini muburyo bwo kubona amashusho, niba ugereranije, hamwe na 100 Hz. Mugihe igikoresho kigenewe gukoreshwa cyane nka monitor yimikino ya videwo cyangwa kanseri, kimwe nibindi bice byimyidagaduro, ndetse no kureba firime zifite ingaruka zidasanzwe cyangwa zikemurwa cyane,
Ubundi buryo ukeneye kwitondera hertz nugukoresha TV murwego rwo hejuru kugirango urebe amashusho afite imbaraga kuri ecran nini. Ibi birimo amashusho gusa muri firime, ariko kandi harimo umupira wamaguru nindi mikino ya siporo, amasiganwa yimodoka, ibindi birori byihuta cyane, imbyino, ibitaramo hamwe nibintu byinshi byimuka. Muri iki kibazo, birasabwa guha amahirwe ibikoresho bihenze no kugura TV ya hertz 200. Twakagombye kuzirikana ko uko imbaraga zigenda zihuta, umuvuduko wikintu cyangwa umuvuduko wurugendo rwinzira yacyo, niko bigaragara cyane itandukaniro riri hagati yibikoresho kuri 60 na 120 Hz. Niba ubwiza bwa videwo bwambere buri hasi (kurugero, kwakira televiziyo nabi),

Kugereranya hertz zitandukanye

Nyuma yuko bimaze kugaragara icyo umubare wa hertz muri monitor cyangwa televiziyo bigira ingaruka, ugomba kugereranya ibipimo bitandukanye. Nkurugero, birasabwa gufata amahitamo azwi cyane – 60 Hz na 120 Hz.
Ihererekanyabubasha rishobora kubyara hamwe nubuziranenge bwibishusho na TV ya 50 cyangwa 60 ya hertz. Niyo mpamvu ubusanzwe imigezi isakara hamwe nibipimo nkibi. Mugihe mugihe umurongo umwe ucurangwa kuri TV ifite imikorere ya Hz 120, buri kintu gikubiye mumigezi, mubyukuri, kizikuba kabiri. Umukoresha azarangiza afite ama frame 120 kumasegonda. Televiziyo zigezweho zirashobora guhinduka kuva 120Hz ikagera kuri 60Hz yo kugarura ibintu byikora. Ibi bisaba ikintu kimwe gusa cyujujwe, ko hari ibimenyetso byerekana amashusho, ni ama frame 60 kumasegonda. Nyuma yo gusesengura kugereranya, biragaragara ko ko udakeneye kugura TV cyangwa monitor hamwe nigipimo gishya cya Hz 120 kugirango urebe bisanzwe mubisanzwe byerekanwa – umukoresha usanzwe ntazabona itandukaniro riri hagati ya 60 Hz. Niba ibikoresho byaguzwe kugirango habeho umukino, noneho nibyiza gukoresha neza Hz 120, kubera ko muriki gihe ishusho izahinduka neza kandi yoroshye, kandi amaso ntagabanuka. Ni nako bigenda kuri izo manza iyo ukora kuri mudasobwa / kureba TV bifata amasaha arenze 2 kumunsi.
Ibyiza bya TV hamwe na monitor hamwe na ecran ya ecran ya 120 Hz izongerwaho amashusho neza. Amashusho mugihe cyo gukina asa neza kuri TV ya 120Hz ugereranije nigikoresho cya 60Hz. Kandi, niba uhisemo TV ya 120Hz, urashobora kongeramo interpolation kumasoko ya 60Hz. Televiziyo zifite amanota menshi zikoreshwa gake. Bashyizweho, kurugero, mumikino yo murugo kugirango bagere kwibiza cyane mwishusho, kugirango babone amabara yose nigicucu gishoboka mugihe bakora mubanditsi batandukanye. https://cxcvb.com/texnika/domashnij-kinoteatr/2-1-5-1-7-1.html
