Kudziwa Zomwe Mungayang'ane Pogula Kuwunika kwa CRT kwa PC yanu
Chifukwa cha kukula kwawo ndi zotsatira zake zachilengedwe, mawonekedwe achikulire a CRT sagwiritsidwa ntchito kwa ogulitsa ambiri ntchito. Ngati mukuyang'ana kuti muwonetse kompyuta yanu, yang'anani Guide yanga yowunikira bukhu la LCD yomwe imatanthawuza zochitika zosiyanasiyana ndi mateknoloji kumbuyo kwa mawonetsero amakono a makompyuta.
Cathode Ray Tube kapena CRT oyang'anitsitsa ndiwo mawonekedwe akale kwambiri pa makompyuta a PC. Makompyuta ambiri oyambirira anali ndi mawonetsedwe awo ku kanema ka kanema kawiri kawiri komwe kawonetsedwe pa TV nthawi zonse. Pamene nthawi ikupita, momwemo makanema ogwiritsira ntchito makompyuta amasonyeza.
Yang'anani Kukula ndi Malo Osavuta
Onse oyang'anira CRT amagulitsidwa malinga ndi kukula kwawindo. Izi ndizomwe zili zolembedwa pamzere woyerekeza kuchokera kumunsi wapansi mpaka kumbali yapamwamba ya chinsalu. Komabe, kukula kwa mawonekedwe sikukutanthauzira kukula kwake kwawonetsera. Tizilombo toyang'anitsitsa timayang'aniridwa pang'ono ndi mawonekedwe a kunja. Kuwonjezera apo, chubuyo silingathe kupanga chithunzi kumbali zonse za chubu. Momwemo, mukufunabe kuyang'ana chiwerengero chowonekera chomwe apangidwa ndi wopanga. Kawirikawiri malo omwe amawonekeratu kapena owonekera a mawonekedwewo adzakhala pafupi .9 mpaka 1.2 mainchesi ang'onoang'ono kusiyana ndi chubu.
Kusintha
Onse oyang'anitsitsa CRT tsopano akutchulidwa kuti oyang'anitsitsa multisync. Chowunikiracho chimatha kusintha mtengo wa electron kotero kuti ukhoza kusonyeza malingaliro angapo pazomwe zimatsitsimula. Pano pali mndandanda wa ziganizo zomwe zimagwiritsidwa ntchito kawirikawiri pamodzi ndi chiganizo cha chigamulochi:
- SVGA = 800x600
- XGA = 1024x768
- SXGA = 1280x1024
- UXGA = 1600x1200
Pali ziganizo zosiyanasiyana zomwe zilipo pakati pa ziganizo izi zomwe zingagwiritsidwe ntchito ndi kufufuza. Pafupifupi 17 "CRT iyenera kuchita bwino SXGA ndipo ingathe kufika ku UXGA." 21 CRT kapena yochulukitsa CRT iyenera kuchita UXGA ndipamwamba.
Zosintha Zotsitsimula
Patsiku la kutsitsimula limatanthawuza kuchuluka kwa nthawi yomwe pulogalamuyi imatha kudutsa dera lonse pazithunzi. Mpikisano umenewu ukhoza kusintha mosiyana ndi momwe makasitomala alili pa kompyuta yawo komanso zomwe khadi lavideo lomwe likuyendetsa liwonetsero. Zomwe zimatsitsimula ndi opanga makina amatha kulemba mlingo wokwanira wotsitsimula pa chisankho choperekedwa. Nambalayi yalembedwa ku Hertz (Hz) kapena maselo pamphindi. Mwachitsanzo, pulogalamu yowonongeka ingathe kulemba zinthu monga 1280x1024 @ 100Hz. Izi zikutanthauza kuti chowunikiracho chikhoza kusesa chinsalu katatu pamphindi pa chisankho cha 1280x1024.
Nanga bwanji chifukwa cha mphindi zotsitsimula? Kuwona chiwonetsero cha CRT kwa nthawi yaitali kungayambitse kutopa. Mawotcheru omwe amathamanga pafupipafupi adzawonetsa kutopa uku mufupikitsa nthawi. Kawirikawiri, ndi bwino kuyesa kupeza mawonetsero omwe angasonyeze pa 75 Hz kapena bwino pazomwe mukufuna. Hz 60 imatengedwa kuti ndi yochepa ndipo ndiyomwe imakhala yowonjezera kutsitsimula kwa oyendetsa kanema ndi oyang'anitsitsa mu Windows.
Dot Pitch
Amapangidwe ambiri ndi ogulitsa samakonda kulemba ndondomeko yowonjezereka. Chiwerengero ichi chimatanthawuza kukula kwa pixel yopatsidwa pazenera mu millimeters. Izi zakhala zovuta zaka zapitazi monga zojambula zomwe zinayesa kupanga ziganizo zazikulu ndi zolemba zazikulu zadothi zimakhala ndi chithunzi chosasangalatsa chifukwa cha mtundu wa magazi pakati pa pixels pawindo. Zosankha zazitali zochepa zimasankhidwa pamene zimapereka chiwonetsero chachikulu cha chithunzi. Zowonjezera zambiri za izi zidzakhala pakati pa .21 ndi .28 mm ndi zojambula zambiri zomwe zili ndi pafupifupi 25 mm.
Kukula kwa Cabinet
Malo amodzi amene ogula ambiri amanyalanyaza pakugula mawonekedwe a CRT ndi kukula kwa kabati. Owonetsa CRT amakhala otetezeka kwambiri komanso olemera ndipo ngati muli ndi deki yochepa, mungathe kukhala ochepa kukula kwazomwe mungakwanitse mu malo opatsidwa. Izi ndizofunikira makamaka pa kuya kwa pang'onopang'ono. Ntchito zambiri zamakompyuta ndi desiki amakonda kukhala ndi masamulo omwe amayenera kuzungulira polojekiti yomwe imakhalanso ndi nsana. Owona akuluakulu pamtundu wotero amatha kukakamiza kuyang'anitsitsa pafupi ndi wosuta kapena kulepheretsa kugwiritsa ntchito makina.
Kutsutsana Kwachitsulo
Ma CRT akuwonetsa tsopano ali ndi mikwingwirima yambiri kumbuyo kwa chinsalu kapena chubu. Zipangizo zoyambirira zofanana ndi TV zomwe zili ndizomwe zimapangidwira n'zosavuta kuti dothi lamakonzedwe lopangidwira likhale losavuta kupereka chithunzi choonekera. Pamene zipangizo zamakono zinkapitirira, zowonongeka zowonongeka zinafika zomwe zinali ndi makondomu kumanzere ndi kumanja koma malo ophwanyika pamwamba. Tsopano a CRT oyang'anitsitsa alipo ndi zowonongeka zowonongeka kwa malo opingasa ndi ofukula. Kotero, kodi mkangano uli chiyani? Mawindo odzaza mawindo amatha kusonyeza kuwala komwe kumapangitsa kuwala kwasalu pawindo. Mofananamo ndi mitengo yochepa yotsitsimula, kuchuluka kwa makina pa kompyuta kumapangitsa kuchuluka kwa kutopa kwa maso.
