Ukuthenga i- TV entsha kuyinto ebalulekileyo, ngoko kuyimfuneko ukuyiphatha ngayo yonke inxaxheba kunye nolwazi. Iingcali zincoma ukutshekisha i-TV ngamaphikseli aphukileyo kunye nomthengisi-ncebisi ngokuthe tye.
Iyintoni ipilisi kwiTV?
I-matrix yommkeli we-TV yinani elikhulu lamaseli amancinci. Le yile pixels. Umgangatho womfanekiso uxhomekeke kwinani lamaphikseli: ngaphezulu kwabo, icacile umfanekiso. I-pixel nganye yombala weTV, kwakhona iqukethe i-subpixels: ebomvu, eluhlaza okwesibhakabhaka kunye nohlaza.
Isisele esingaphenduliyo kwishintsho lesignali sisisiphako, esibizwa ngokuba yi "pixel ephukile". Ibonakala ngokwamanqaku ombala ofanayo, owonayo umfanekiso oboniswe kwisikrini. Zikhona iintlobo ezilandelayo zokuphulwa kwepikseli:
- Iipixel ezimhlophe - iindawo ezivuthayo;
- i-pixel emnyama - isebenzi engasebenzi;
- iipekseli ezibomvu, eziluhlaza okanye ezihlaza okwesibhakabhaka - isiphene se-subpixel;
- ubukho bezinto ezimbini okanye ezintathu.
Ungajonga njani iipikseli kwiTV?
Ukuhlolisisa iipekseli kwiTV kuyona nqanaba elinzima ekuvavanyeni idivayisi phambi kokuthenga. Indlela elula yokuqinisekisa kukuba uhlolisise isikrini xa kukho nawuphi na umbala oboniswe kuwo. Ukufumana amachashaza amnyama, kufuneka ungenise ibhokisi elimhlophe. Ngoko ke, ukufumanisa amaphupha amhlophe, kusetyenziswa insimba emnyama. Ukukhangela iziphene ze-subpixel (amanqaku ombala), utshintsho lombala wesikrini luya kutshintsha. Ekuhloliseni okufutshane, nangona isohlo limeyile, kunokwenzeka ukufumanisa iziphoso, kodwa kungcono ukusebenzisa iglasi yokukhulisa ukwenza inkqubo yokuhlola iipekseli eziphukileyo ngokufanelekileyo.
Kwiimodeli zanamhlanje zamashishini kukho okwakhiwa kwimisebenzi yemenyu yokuvavanya i-TV ngamaphikseli aphukileyo. Xa kuvuliwe, isikrini sexesha elithile limibala ngemibala efanayo, okwenza kube lula ukubona ipiksile engenaphutha. Ukuba umsebenzi onjalo awunikeziwe, ke kwiivenkile ezikhethekileyo kukho iirakhi ezikhethekileyo ezibonelela ngemimandla emnyama, emhlophe kunye nembala kwi-screen yesikrini, kunye neenkqubo zokuvavanya. Umzekelo, i-Nokia Monitor Test yenza kube lula ukujonga iipekseli eziphukileyo, i-moire (indawo ezikhanyayo) kunye nezinye iziphene.
I-pixel ephukile kwiTV: isiqinisekiso
Ngelishwa, ukunikezela okanye ukutshintshela i-TV nge pixel ephukile kaninzi ayinakwenzeka. Inyaniso kukuba ngokwemigangatho ekhoyo yamazwe ngamazwe, kwi-teknoloji yeklasi nganye, inani elincinci elivumelekileyo leepekseli elinesiphako linikezelwa. Ngoko, ngokuhambelana nemigangatho, kuphela kwiklasi ye-TV yokufumana iimpazamo zeepiksile azivunyelwe. Inkqubo yesibini yesibini ibakala ingatshintshi kuphela ukuba umda wokumiselwa kwemvume ugqityiwe.
Unyango lweepikseli eziphukileyo kwiTV
Ngokuqhelekileyo, abasebenzisi bethekhnoloji yethelevishini, sele besetyenziselwa ukuyisebenzisa, bafumanisa ukuba ipilisili embi ibonakala kwiTV. Ndifuna nje ukunilumkisa ukuba akunakwenzeka ukulahla amaphupha amnyama ngawe. Kodwa ama-pixel aphukile adibeneyo anokupheliswa ngokwawo. Kukho iindlela ezimbini:
- Ukusasaza indawo engalunganga. Ukuze "ukuhlalisa" i-cotton swab ifanelekile.
Kubalulekile ukuchonga ngokuchanekileyo indawo yeepikseli eziphukileyo, cima iTV uze ucindezele kule ndawo ixesha elide. Phinda ulandelelanise iinkqubo eziliqela. - Massage. Unyango luyenziwe ngokusebenzisa iinkqubo ezizodwa ukususa iipekseli ezinamathelweyo ezingatholakala kwi-intanethi. Indlela yesibini inika amathuba amaninzi "okuphilisa" isikrini, ngaphandle koko kukhuselekileyo kwisixhobo. Abaphuhlisi besebenzi bathi isiphene sinokupheliswa kwiminyaka emininzi yemizuzu yale nkqubo.
Kukho nezinye iingxaki zeTV.
