Ukujonga: khangela iipekseli eziphukileyo xa uthenga

Xa kuthengwa iliso, ukujonga iipekseli eziphukileyo - inkqubo ayikho into engafanelekiyo. Iyintoni "iphaxel ephukile" kwaye kutheni kuhlolwe ukuba ihlolwe? Ukuthenga abathengi abakude kwimigca yokuvelisa kunye nokusebenza kwezikrini zeLCD / abagadi bamabonakude / ithelevishini konke oku kuvakala ngokungavamile kwaye kungaqondakali.

I-monitor ye-LSD iqukethe amachashaza amancinci (iipekseli) ezivelisa ukukhanya nombala. I-pixel ephukile i-pixel ephosakeleyo engasebenzi kakuhle. Ingaba ayisebenzi ngaso sonke ixesha (idayi emnyama), okanye ihlala ishisa ngombala ofanayo (umhlophe, obomvu, obomvu okanye obomvu), kungakhathaliseki ukuba umbala womfanekiso. Ukukhangela iipikseli eziphukileyo kukuvumela ukuba ubone ukuthenga ngaphambi kokuthenga kwaye ubuze umthengisi ukuba athathe umkhiqizo ongenasiphelo. Ukungahoyi ikhefu kuvumela abanye abathengisi abangenangqiqo ukuba babone iimpahla ezingenzi kakuhle ngamabhengi abanamava.

Hlola iliso kwiipekseli eziphukileyo - eqinisweni, inkqubo elula kwaye elula. Yinyaniso. Kwanele ukuba ne-flash drive kunye nawe xa uthengisa inkqubo ukujonga iipekseli eziphukileyo kunye nemizuzwana embalwa yexesha ukuqala le program. Emva kokufakela inkqubo kule mizuzu embalwa ungabona oko uza kuhlawula khona igazi lakho. Njengomthetho, nayiphi na umthengisi, ozazisa igama lakhe, akayi kuphazamisa inkqubo yokuqinisekisa.

Amagama ambalwa malunga nenkqubo ekufuneka ibe yintoni. Ukujonga iipikseli eziphukileyo zikho iintaba ze software. Usebenza ngokugqithiseleyo. Emva kokufaka kunye nokuqhuba inkqubo, yonke indawo yeso siqendu iveza umbala omnye. Ukujonga umlenze weepikseli eziphukileyo ngokucinezela inkinobho ye mouse. Olu shicilelo lushintsha umbala weso saziso. Xa utshintsha imibala, ungabona iipekseli eziphosakeleyo (eziphukile).

Akunakuqonda ukuluhlu zonke iinkqubo ezikhoyo zokuvavanya iipekseli eziphukileyo. Naliphi na injini yokukhangela yombuzo "hlola iprogram yeepikseli eziphukileyo" kuza kuvelisa amaphepha angamakhulu amaninzi, anxulumene nokukhuphela. Khetha nayiphi na, khuphela, uvavanye uze uphonsa kwi-flash flash drive. Kulo venkile, uya kukunika uncedo oluxabisekileyo, ugcine imali, ixesha, amaninzi.

Kutheni kubalulekile ukuhlola ngaphambi kokuba uthenge? Emva koko, kukho umthetho kwicala lomthengi, kwaye iimpahla zingabuyiselwa okanye zitshintshwe ngumthetho. Ewe, kunjalo. Nangona kunjalo, umthengisi akahlali ekulungele ukutshintshisana, ngokubhekiselele kumgangatho oqhelekileyo we-ISO 13406-2, ovumela inani elithile leepikseli eziphukileyo kunye nalokhu akuthathwa njengomtshato.

Eyona nto inomdla kukuba le nyaniso. Lo mgangatho ubeka impawu ukuba i-LCD iqaphele ibe nayo (ukukhanya, umbala, ukufanisana kokukhanyisa, njl.). Enye yeerameters iyinombolo eyamkelekileyo yamaphikseli angalunganga. "I-Spot" - ayikho iipekseli ezingapheliyo ezimbini, iisentimitha ezili-17 ukuya kweye-19 - ezingekho ngaphezu kwezine, ii-intshi ezingama-21 kunye nezinye - ezingekho ngaphantsi kweesithandathu.

Abavelisi beepaneli zeLCD baqhelekile ngokuqhelekileyo ngala manani. Kwaye, ngokusekelwe kulo, kukho ukwahlula kwamatrices e-LCD kwiiklasi zekhwalithi: iklasi yokuqala ayinayo nayiphikseli ephukile, yesine ivumela iiyunithi ezingama-256 ezingafanelekanga. Nceda uqaphele: abavelisi bentengiso abavelisi iindlebe eziphantsi kweklasi yesibili. Ngokwemiqathango, "akukho mveliso" engekho nawuphi na umgangatho. Khangela iipekseli eziphukileyo kule meko ziyimfuneko nje.

Nangona imali yakho isesikhwameni sakho - umthengisi uya kwenza yonke imizamo yokwenza kakuhle: xelela, bonisa, uvavanye kunye nawe, wuthathe indawo (ukuba kuyimfuneko) okanye ukhethe omnye umzekelo. Kodwa ngokukhawuleza ukuba uhlawule imali waza wuthatha impahla-iqondo lokunyameka liwela ngokukhawuleza. Awukwazi ukuthengisa umthengisi oyithandayo. Kule khosi kunokuhamba ukungaziphambuki ngamabomu kolwazi, ukuchazwa kwamahhala kwemimiselo kunye nezenzo, ukudibanisa namaxwebhu angabikho. Ukubuyisela ubulungisa, kufuneka uhlambele "abaphathi" abanenkani, kwaye emva koko, (ubulungisa) akunakuze kuhlaziywe.

Ukuhlolisisa iipikseli eziphukileyo akuyiyo. Oku kuyimfuneko efanelekileyo, eya kukunceda yokwenza nokuthenga nokusetyenziswa kwe-monitor njengamnandi njengoko kunokwenzeka.
