Phindu lachitsulo - chomwe chiri chabwino? Kodi pafupipafupi pulogalamuyi?

Zina mwazofunikira zamakono zamakono ndi ma TV ndizomwe zimatsitsimula. Kodi ndizifukwa zotani zomwe parameteryi imaloledwa? Ndi liti pamene kuli kofunika kusintha pamanja? Kodi ndizochitika zotani zomwe mtunduwu sukuchita?

Kodi maulendo a pulogalamuyi ndi otani?

Kompyutala ikuyang'ana kapena mawonekedwe a pa TV akugwira ntchito molingana ndi mafelemu ofanana. Izi ndi zofanana ndi kanema wa film. Mpangidwe wa mawonekedwe a filimuyi ndi pafupifupi 25-30. Pankhani ya pulogalamu ya PC kapena sewero la pa TV, chizindikiro ichi chiyenera kukhala chapamwamba, chifukwa chithunzi chomwe chimangidwe ndi chovuta kwambiri kuposa kanema pa filimuyi. Lamuloli ndiloti chiwerengero chafupipafupi chimakhala chithunzi, ndipo chimasangalatsa kwambiri ndi kuyang'ana pazenera.

Mafupipafupi ndi mtundu wawindo

Pali mitundu yambiri yamakono yopanga makanema ndi oyang'anira. Zamakono - ndi LCD, LCD ndi LED. Zomwe zimakhala zosawerengeka zimatengedwa CRT. Nthawi zambiri kusinthidwa kwa LCD TV kapena kuwunika chithunzi (kugwiritsa ntchito teknoloji yomweyo) kumatsimikiziridwa molingana ndi mfundo zina kuposa momwe zimagwiritsira ntchito zipangizo zamakono zowonongeka. Pankhani ya kuwonetsera kwa LCD, chithunzichi chimachokera pazenera nthawi yomweyo.

Ngati tikukamba za CRT-mawonetsero - mzere ndi mzere. Choncho, ngati pulogalamu yotsitsimula ya LCD TV ndi electron beam unit ndi yofanana, ndiye khalidwe lomwe liri ndi mwayi waukulu lidzakhala losiyana ndi chipangizo cha mtundu woyamba. Komanso, ngati chiwerengero chofananacho chiri pafupifupi HZ 60 (chiwerengero cha zosintha zowonetsera pamphindi), ndiye kuti ngati CRT-oyang'anitsitsa kuyang'ana idzaonekera kwambiri.

Mafupipafupi okhala ndi ma CRT

Choncho, tidzakhala osamala kwambiri pakukonza mawonetsero a electron-beam. Momwe mungasinthire mlingo wokonzanso wawonekedwe wa CRT mu Windows ndi chitsanzo cha XP version? Ndi zophweka kwambiri. Muyenera kulowa "Control Panel". Kenako sankhani "Screen". Mutatsegula mawindo ofanana, muyenera kupeza tabu ya "Parameters". Kenako dinani "Advanced". Pakhoza kukhala mndandanda wa zosankha zingapo.

Kodi mlingo wabwezeretsani wotchinga ndi chiyani? Kwa oyang'anira CRT, mtengo woyamikira ndi 85 Hz. Ngati chiwerengerochi sichipezeka mndandanda, ndizotheka chifukwa choti dalaivala wa fakitale ya makanema sangakonzedwe pa PC. Iyenera kumasulidwa pa intaneti kapena kufufuza pa ma disks omwe anaphatikizidwa ku PC pamene mukugulitsa. Mukhozanso kuyesa kulumikizana ndi chipatala kuti muthandize dalaivala.

Ma CRT: maonekedwe

Onani kuti pafupifupi pafupifupi njira zonse zogwiritsira ntchito, ndizotheka kusintha mtundu wotere ngati mphindi yotsitsimula. Mawindo 7 ndi omwe akuwongoleratu, ndipo zikuwoneka, osasowa zofunikira kwambiri pakukonzekera kwa osuta, ndizosiyana. M'masinthidwe awa a OS, ndondomeko yothetsera magawo oyenerera ndi ofanana. Kupyolera mu "Pulogalamu Yoyang'anira" chiwerengero chotsitsimutsa chofunika chimayikidwa. Kodi njira yabwino kwambiri yogwiritsira ntchito ikuthandizani kuti muyike malo oyenera? Pafupifupi Mabaibulo onse a Windows amagwira ntchitoyi mofanana. Komabe, pokhudzana ndi mavoti atsopano a OS (omwewo Mawindo 7), iwo akhoza kukhala ndi mavuto ena ndi madalaivala a zipangizo zosatha. Koma zimathetsedwa - monga lamulo, mapulogalamu aliwonse a mtundu woyenera angapezeke pa intaneti.

Komanso, pamene mukugwira ntchito mu Windows 7, njira yolumikizira zofunikira zosiyana ndizochitika mu XP. Muyenera kulowa mu "Pulogalamu Yowonetsera", kenako dinani pa "Screen", kenako - sankhani kusintha kwake. Kenaka dinani Zapangidwe Zapamwamba. Kenaka, pitani ku "Tsambulati" tab, kumene ife timapeza maulendo afupipafupi.

Tawonaninso - poika mawindo onse a Windows pazinthu zoyenera, musati muzimasula bokosi "Bisani njira zomwe osamala sangagwiritse ntchito". Chowonadi ndi chakuti teknoloji pulogalamuyi, ndithudi, imatha kugwira ntchito ndi zochitika kunja kwa zoyenera. Koma pakuchita izi zingayambitse mavuto ndi bata la PC. Choncho, ngati wogwiritsa ntchito akufunsa momwe mungasinthire mlingo wawotsitsimula wa chinsalu, ngati choyimira chofunikirako sichipezeka, ndipo mfundo zomwe zilipo zili zochepa kusiyana ndi zomwe zikufunira CRT zojambula, chinthu choyamba chimene timamupempha ndicho kukhazikitsa madalaivala atsopano pa khadi la kanema.

Chilolezo chovomerezeka

Nthawi zina, khalidwe la zithunzi pawonetsedwe la CRT limadalira chisankho. Pazikhalidwe zake zapamwamba, palinso zinthu zambiri pazenera. Ndipo mwachitsanzo, ndi zithunzi kapena mavidiyo, n'zotheka kuziwona mwatsatanetsatane. Zomwe mulingo woyenera kuchita zimadalira, choyamba, pa kukula kwa mawonekedwe a masentimita. Koma, kwenikweni, wogwiritsa ntchito akhoza kuyesa kukhazikitsa mfundo zosiyana. Dziwani kuti mutha kusintha ndondomekoyi pogwiritsira ntchito ndondomeko yomweyo monga momwe mukusinthira pafupipafupi - kudzera pa "Control Panel" ndi "Screen".

Onaninso kuti ngati chigamulochi chikukwera kwambiri, kuyika 85 Hz sikungatheke nthawi zonse. Ndipo izi, mwa njira, ndi chimodzi mwa zifukwa zomveka chomwe chiwerengero chokhumba sichingakhale pa mndandanda wafupipafupi. Choncho, ngati madalaivala ali ocheperapo, ndipo 85 HZ sali mndandanda, mungayese kuchepetsa pang'ono kuthetsa kusamalitsa.

Nthawi zambiri mawonedwe a LCD

Tiyenera kukumbukira, kuchuluka kwa kusinthika fanoli pawindo la LCD - nthawi zambiri, chizindikiro chomwe chilibe phindu. Chifukwa chakuti zowonongeka zamakono zamakono zili kale fakitale kuti kusintha kosasinthika sikungoyesedwe. Ngakhale kuti ndi ofanana ndi HZ 60, zomwe zingakhale zovuta kuwonetsera CRT, sipadzakhalanso kuonekera kwa fano chifukwa cha zamakono zomwe tazitchula pamwambapa. Komabe, ponena za mawonetsedwe a LCD, gawo lina ndilofunika kwa iwo - mlingo wokonzanso mpikisano. Nthaŵi zambiri, mwa njira, amadziwika ndi "mafupipafupi" a chinsalu - ngakhale pakati pa akatswiri a IT. Izi, zenizeni, sizowona kwathunthu. Zosavuta chifukwa chakuti liwiro la kupangidwanso kwa ma pixel siliwonetsedwa mu hertz, koma mu unit - mamilliseconds. Koma ngati mawuwa agwiritsidwa ntchito pamutu wa "mafupipafupi", palibe, mwina, atidzudzula chifukwa chosowa kuwerenga. Choncho, timagwiritsa ntchito mawu akuti "mafupipafupi" mawonetsero a LCD, tidzamvetsetsa ngati "mpikisano wotsitsimula".

Kotero, kodi ndiwuni yapamwamba yowonetsera zowonetsera mu LCD oyang'anitsitsa? Chinthu chofunika kwambiri ndikutsimikizira kuti makalatawa ndi ofanana ndi makhadi a makompyuta. Izi zikutanthauza kuti, ngati, chipangizochi chidzapanga chithunzi ndifupipafupi 60ttz, ndipo kuyang'ana kwa LCD sikudzakhala ndifulumira kukonzanso ma pixel (omwe angawonedwe ngati chizindikiro cha pafupi 30-40 milliseconds), ndiye chithunzi pachiwonekera chimawoneka "chikuyandama" . Zing'onozing'ono zomwe zimagwirizanitsa pazithunzi, zimakhala bwino. Momwemo, iyo siidapitilira millisecond 15. Monga lamulo, funso la momwe mungapititsire mafupipafupi a kusinthira mtundu wa mawonekedwe a LCD sizothandiza. Mofananamo, liwiro la kukonzanso ma pixel - njira zambiri nthawi zambiri, fakitale. Kusintha kwanu kunyumba kumakhala kovuta. Choncho, ndi bwino kumvetsera mwatcheru pamene mukugula chinsalu.

Zojambulajambula

Zomwe zili zofananako zimakhalanso ndi zida zina zamagetsi zomwe zimagwiritsa ntchito maonekedwe a LCD. Izi ndizo, phindu la pulogalamu yowonongeka - choyimira ndi "chatsekedwa" kuti chikonzedwe, monga momwe zilili ndi oyang'anira PC.

Kusiyanitsa kotheka mu khalidwe la chithunzi pawonetsedwe kowonongeka kowonongeka kumayambiriro kawirikawiri kumadalira pafupipafupi zoyenera. Pafupipafupi, chinthu chofunika kwambiri ndi msinkhu wa matekinoloje omwe amakonzeratu, makamaka, liwiro la kukonzanso ma pixelisi. Zosafunikira ndizomwe nthawi zambiri zowonekera zimatsitsimutsa. Kodi ndi luso lanji lapamwamba popanga chithunzi kuchokera pakuwona "pixelization" ndi kutembenuza mtundu kwa mtundu wina woyang'anila? Choyamba, wotulutsa mtundu amawunikira. Zithunzi za mitundu yosatha, ndithudi, ikhoza "kutaya" osati chithunzi chabwino. Koma zogulitsa zamakono, monga lamulo, palibe mavuto aakulu ndi iwo. Onaninso kuti kuwonjezera pa "nthawi", khalidwe la chithunzi likukhudzidwa ndi zigawo zambiri zomwe zimakhala zojambula pa PC ndi laputopu. Chisankho ichi, mtundu wa matrix, maonekedwe a khadi lavideo.
