Ndi mlingo kulunzanitsa Kodi

Mu nthawi ya oyang'anira ndi mawailesi akanema, analengedwa pa maziko a CRT (cathode ray chubu), munthu aliyense anali ndi osachepera kukhala ndi chithunzithunzi cha zimene mlingo kulunzanitsa. Pokhapokha, ndithudi, kunali kofunika kwa kuti apulumutse

masomphenya, mayeso, kupweteka m'munsili kusapeza pamene ntchito pa kompyuta kapena kuonera TV. Tikhoza kunena kuti chophimba mlingo kulunzanitsa anali kungotchula ofanana thanzi. Masiku ano, zinthu wakhala ukasintha obrazomizmenilas. Iwo unalengedwa mawonekedwe mudziwe anasonyeza chipangizo ntchito mfundo chosiyana ntchito kuposa luso CRT. Ngakhale LCD chophimba ndi oyang'anira TV si wangwiro, kulankhula za chitetezo kwathunthu amene amadza pa masomphenya kwambiri yafupika, koma osati kwambiri.

Kuyankha funso kodi nsalu yotchinga kulunzanitsa mlingo, ndi chophweka eni oyang'anira kompyuta. Ngati mumamwa dongosolo Windows ntchito Baibulo atsopano, m'pofunika danga aliyense kwaulere pa kompyuta amasonyeza menyu mwa kuwonekera lamanja mbewa batani, ndi mndandanda limapezeka, kusankha "Screen Maonekedwe." Kenako, chitani ndi "Zikhazikiko mwaukadauloZida". Apa, tsamba kutsegula "Muziona", mukhoza kuona mzere "oyendetsa kuonerera kulunzanitsa."

Mu oyang'anira masiku ano zochokera timibulu madzi, kawirikawiri alipo 59 60 Hz - izo ndi zitsanzo otsika-yotsiriza; mu mtengo mwina ngati 75 100 Hz. Mumalimbikitsa mlingo LCD nsalu yotchinga - zimasonyeza nyengo CRT. The zitsanzo madzi galasi "ndi diso" kusiyanitsa 60 ndi 100 Hz zosatheka. Chinthu chokha chimene tsopano amakhudza angapezeke uku - yosalala kayendedwe ka ndi cholozera mbewa ndi luso logwiritsa ntchito 3D-magalasi (100 Hz chofunika kwa iwo).

Koma mu masiku a CRT izo zinali zosiyana. Pamwamba lamkati la chophimba (chubu) chidafundidwa ndi wosanjikiza zakuthupi wapadera (phosphor) waluso chowala milliseconds ochepa atachita izo ma elekitironi. maelekitirodi atatu (mfuti) ndi umuna wa particles ankalankhula umayenda amene zoyenda kudzudzulidwa maginito. Iwo deflects cheza ku mzere wolunjika kwa woyamba anayamba kuwala chapamwamba kumanzere ngodya ya zenera, ndiye ikuyenda anachititsa luminescence pa mzere yopingasa

chapamwamba pomwe ngodya. Kenako mtengo ankatembenukira pansi mzere onse mobwerezabwereza. Akafike pansi pomwe ngodya, iye anabwerera ku chiyambi ndi chirichonse mobwerezabwereza. chiwerengero cha zowonetsera amenewa achotsedwa kachiwiri ndi ngati ndi mlingo kulunzanitsa.

The LCD Mtsogoleri angabweretse kusintha kufala kwa kuwala kupyolera mu zinthu madzi galasi la masanjidwewo ndi - akhoza imodzi azinyadira ndi kuzima nsalu yotchinga. N'kuti backlight palokha - izi ndi vuto lomaliza kuti inathetsedwa mwakhama zitsanzo watsopano wa oyang'anira. Chophimba phosphor akadali zidawala, polenga nkhambakamwa za chithunzi kwathunthu. Maso alibe nthawi muzindikire kukulowa chifukwa cha kasinthidwe zonse zithunzi. Komabe, analipo, ndipo pomwe mafurikwense pansipa 75 Hz anali ndinasintha masomphenya zotumphukira. Kuthetsa amenewa opanga adafotokoza oyang'anira ngakhale ndi mafurikwense pamwamba 120 Hz. Kumene, zolinga izi wosalira kwa kumvetsa - ife osaganizira mapangidwe mtundu ndi fano liri.
