Gada: uhlole Amaphikseli efile lapho uthenga

Uma ukuthenga qapha kokuhlola Amaphikseli engaphelele - inqubo akuyona engadingekile. Siyini "kwe-pixel efile", futhi kungani kudingeka ihlolwe? Ukuze abathengi abangahlakaniphile neze butholakala enqubweni eyinkimbinkimbi yokuthela zokukhiqiza ukusebenza ka-LCD izikrini / ngabaqaphi / TV konke lokhu umsindo ongaziwa futhi engaqondakali.

LSD qapha liqukethe amachashazi ezincane (Amaphikseli) ukuthi ukukhiqiza kabusha ukukhanya nombala. Dead pixel elingu - kuyinto ngephikseli elibi ayisebenzi kahle. Yena noma akusebenzi ngaso sonke isikhathi (a black dot) noma unomphela ovuthayo e nombala ofanayo (omhlophe, oluhlaza okwesibhakabhaka, obomvu noma oluhlaza), kungakhathaliseki umbala isithombe. Hlola Amaphikseli efile ikuvumela ukubona ukuthengwa womshado zidinga umdayisi ukuba esikhundleni impahla engaphephile. Ukuziba ukuhlolwa evumela ezinye nabathengisi abonakele bona izimpahla ngokusobala engaphelele abathengi ongenalwazi.

Hlola qapha ku Amaphikseli efile - eqinisweni, inqubo elula ngokuphelele futhi elula. Kuyiqiniso. Enough lapho uthenga baphathe USB flash drive lapho uhlelo kulotshwe ukuze uhlole Amaphikseli efile futhi imizuzwana embalwa yesikhathi ukusebenzisa lolu hlelo. Ngokufaka uhlelo emva kwamaminithi ambalwa ungabona, lokho uzokhokha imali yabo. Njengomthetho, yimuphi umdayisi abazisa idumela lawo, ngeke siphazamise inqubo yokuhlola.

A amazwi ambalwa mayelana yini okufanele uhlelo. Ukuze uhlolele Amaphikseli efile kukhona isofthiwe ezintabeni. Isebenza kakhulu ukumane. Emva kokufaka futhi egijima yonke ukubonisa indawo uhlelo esikhanyisa umbala owodwa. Kuqashwe Hlola Amaphikseli efile iwukumane ucindezela sekudla / sandla sesancele inkinobho yegundane. Lokhu cindezela kushintsha umbala qapha. Uma ushintsha imibala nethuba ukubona engaphelele (ngobugebengu) pixels.

Kwenza akukho mqondo ukuba uhlu zonke izinhlelo ezikhona ngoba Amaphikseli efile test. Noma yimuphi injini yokusesha ngesicelo "uhlole Amaphikseli efile uhlelo" kuyonikeza amakhulu amakhasi ane izixhumanisi ukulanda. Khetha noma iyiphi, landa, ukuhlolwa, bese wehlisa induku. Esikhathini esitolo ke izokunikela usizo olungenakuqhathaniswa londoloza isikhathi, imali, eziningi izinzwa.

Kungani kubalulekile ukuba ukuhlole ngaphambi kokuyithenga? Phela, umthengi uhlangothi umthetho, futhi umthetho izimpahla ungabuyela noma exchange. Yebo, libalulekile. Nokho, umdayisi akuyona njalo uzimisele ukuya ku-exchange, ebhekisela ISO 13406-2 ejwayelekile, okuvumela inombolo ethile Amaphikseli efile futhi akubhekwa umshado.

ezithakazelisayo kakhulu ukuthi lokhu kuyiqiniso. Le ndinganiso sinquma izici, okuyinto Kumele ube LCD isibonisi (ukukhanya, imibala, ukufana sokukhanyisa, njll). Omunye nemingcele - inombolo kuvunyelwe pixels engaphelele. "Nanhlanu" - akukho Amaphikseli engaphezu kwemibili onesici, 17-19 amayintshi - akukho kuka amane, 21 amasentimitha noma ngaphezulu - angaphezu kwayisithupha.

Abakhi LCD panel ngokwemvelo ujwayelene lezi zibalo. Futhi, ngokusekelwe lokhu, kukhona ngokuhlukana-matrix LCD phezu amakilasi izinga: ekilasini lokuqala liqukethe akukho Amaphikseli efile, 256 izimvume yesine amayunithi engaphelele. Qaphela: abakhiqizi brand ungenzi ngabaqaphi ngaphansana nekilasi lesibili. Ngakho, «akukho-igama» izinto kungaba noma yini oyifunayo izinga. Hlola Amaphikseli efile kulokhu uyisidingo.

Uma nje imali yakho namanje ephaketheni lakho - umdayisi uzokwenza konke okusemandleni akhe ukuze kukujabulise: tell, bonisa, asethule kanye nani izohlola, esikhundleni (uma kunesidingo) noma ukhethe enye imodeli. Kodwa uma uke ikhokhwe imali futhi wathatha izimpahla - degree of ngesisa ngokushesha falling. Awukwazi ukufunda umdayisi amthanda kakhulu. Ngokuhamba ungaya ukuhlanekezela ngamabomu kolwazi, incazelo khulula izindinganiso neziqondiso, inkomba imibhalo abekho. Buyisa ahluleli, uzodinga Butt nge nenkani "umphathi", ngisho ke (bulungisa) akuyona njalo kungenzeka ukuba alulame.

Ukuhlolela Amaphikseli engaphelele akuyona bethanda. Lokhu ulungisiswa isidingo ukusiza ukwenza futhi yokuthenga nokusebenzisa Ukuqhubeka qapha kahle ngangokunokwenzeka.
