Iyiphi izinga lokuvuselela isikrini

Kwiintsuku zee-CRT kunye neethelevisions (i-cathode ray tube), wonk 'ubani wayenokuba nombono oqhelekileyo wendlela izinga lokuvuselela kwesikrini. Ukuba, ngokuqinisekileyo, kubalulekile ukuba agcine

Umbono, kungekhona ukufumana intloko yesifo kunye nokungahambi kakuhle xa usebenza kwikhompyutheni okanye ubukele iinkqubo zeTV. Singaxelela ukuba izinga lokuvuselela kwesikrini lihambelana ngqo nempilo. Ngethuba lethu, imeko yatshintshile kakhulu. Izixhobo zokubonisa ulwazi olucacileyo zenziwe, kusetyenziswa imigaqo yokusebenza eyahlukileyo kunokuba iteknoloji ye-CRT. Nangona i-LCD yesikrini kwiTV kunye nabagadi be-intanethi ayilungele ngokwaneleyo ukuthetha ngokungabikho kokungabikho kokungabi nengozi: umphumo kumbono ushiye kakhulu, kodwa awuzange ulahleke ngokupheleleyo.

Ukuze uphendule umbuzo malunga nokuba ubukhulu benkcenkceshelo yesikrini lilingana na, yindlela elula kakhulu yabanini beekhompyutha. Kwimeko yokusebenzisa inguqu yakutshanje ye-Windows operating system, kufuneka uvelise imenyu kuyo nayiphina indawo ekhululekile kwideskithophu ngokuchofoza inkinobho ye mouse kwaye ukhethe "Isiqulatho seSkrini" kuluhlu olubonakalayo. Emva koko kufuneka uqhubeke kwi "Options Advanced". Apha, ngokuvula ithebhu "Hlola", ungabona umgca "Hlaziya umvalo wesikrini".

Kwizihloli zanamhlanje zisekelwe kwiikristali zamanzi, i- 59 ne-60 i-hertz zidla ngokufumaneka-oku kubonelelo lweebhajethi; Ngokubiza kakhulu ungasetha i-75 ne-100 Hz. Ireyithi yokuvuselela isikrini seLCD yileli xesha le-CRT. Kwiimodeli ze-crystal zamanzi "ngeso" akunakwenzeka ukuhlukanisa phakathi kwe-60 ne-100 Hz. Into echaphazelekayo yile parameter yinkqubela ehamba phambili yesirathisi semouse kunye nokusebenzisa iiglasi ze-3D (i-100 Hz iyadingeka kubo).

Kodwa ngexesha le-CRT lalihlukile. Umgangatho wangaphakathi wesikrini (ityhubhu) yahlanganiswa nobuncwane bezinto ezikhethekileyo (phosphor), ezinokutshisa ii-millisecond ezimbalwa emva kokuba ii-electron zithinte. Iimodrode ezintathu (izibhamu) zikhupha imilambo yeemitha zengxubevange, isisombululo esilungiswe yintsimi yamandla. Yayiphambukisa imilayezo esuka kumgca ochanekileyo ukwenzela ukuba ikhoneni elingasentla langasekhohlo lesikrini liqale ukukhanya kuqala, ngoko ukuhamba kweza kubangela ukukhanya kumgca ogciniweyo ukuya

Ikhoneni eliphezulu. Emva koko umthamo waguquka omnye umgca phantsi kwaye yonke into yaphindwa. Xa wafika ekhoneni elingezantsi lasekunene, wabuyela ekuqaleni kwaye yonke into ephindaphindiweyo. Inani lalezi zikrini nganye ngesibini lilingana nezinga lokuhlaziywa.

Kwi-controller ye-LCD iyakwazi ukutshintsha ngokukhethekileyo ukuhamba kwesikhanyiso ngokusebenzisa izixhobo ze-matrix zamachiza e-liquid - unako ukukhanya okanye ukucima isikrini. Ukutshatyalaliswa kwesibane sokukhanyisa ngokwayo yintsilelo yokugqibela echithwa ngokutsha kwiimodeli ezintsha zamehlo. I-phosphor kwisikrini yayisakhanya, idala ukungafihli komfanekiso opheleleyo. Iliso nje lingenaso ixesha lokubona isantya esibangelwa ukuhlaziywa rhoqo komfanekiso. Nangona kunjalo, kwakukho, kwaye ukuhlaziywa kwamaxabiso angaphantsi kwe-75 Hz kwakucatshulwa ngokucacileyo. Ukuphelisa le mpembelelo, abavelisi banikezela abagadi bee-frequencies kwi-120 Hz. Ngokuqinisekileyo, icebo elichaziweyo lilula ukuqonda - asiqwalasele ukubunjwa kombala kunye nomfanekiso ngokwawo.
