Amaphikseli aphukile ekuqapha. Incazelo yenkinga nezindlela zokubhekana nazo.

Esikhathini sethu, noma yikuphi umsebenzisi wezinto zanamuhla zamakhaya nezomshini, inkulumo ethi "amaphikseli aphukile" ayibangeli noma yini enye ngaphandle kwekhanda kanye nomoya omubi. Kodwa yini ngempela, futhi kungakanani kubi, ukuba ngumnikazi "ojabulayo" wezobuchwepheshe ngezi pixel ezishaywe kakhulu?

Okokuqala, ake sibheke izimiso zamathelevishini zanamuhla nabaqaphi. I-crystal display ibonisa isithombe ngesethi yamaphuzu, abizwa ngokuthi amaphikseli. Uma bashintsha umbala wabo, isithombe esikrinini sishintsha futhi, futhi sibona isithombe esakhiwe lala maqabunga. Ezingqapheli zanamuhla, i-matrix ifakiwe, ebizwa ngokuthi isebenzayo-kuyo enye i-transistor encane encane-ifilimu inesibopho sokulawula i-pixel ngayinye (yingakho izikrini ezinjalo zibizwa ngokuthi i-TFTs, kusukela ku-English Thin Film Transistor). Uma enye yalezi zithuthazi ihluleka nganoma yisiphi isizathu, singabona into ebizwa ngokuthi i-pixel ephukile ekuqapha.

Ngenxa yokuhluleka kwezobuchwepheshe be-transistor, amaphuzu anjalo awaguqulwa umbala wawo ngesikhathi sokuguquka kwesithombe esibukweni futhi amelela iphuzu elimnyama. Nakuba kufanele kukhunjulwe ukuthi amaphikseli aphukile angeke abe omnyama kuphela - ngemuva kwesizinda esimnyama leli phuzu ngokuvamile limhlophe, futhi kukhona namaphikseli aphuzi, ahlaza okwesibhakabhaka nohlaza okwesibhakabhaka. Ukungasebenzi okunjalo esikhathini sethu kungagcinwa kwi-workshop ekhethekile. Ukuze wenze lokhu, kuyadingeka ukuthi ufake indawo ye-transistor ehlulekile, futhi izokwazi futhi ukwenza imisebenzi yayo.

Kodwa kwenzeka ukuthi amaphikseli aphukile kulesi sikhwama akhiwa hhayi ngenxa yokukhishwa kwe-transistor, kodwa ngenxa ye-okuthiwa i-jamming yamaphoyinti. Ngokuvamile i-jam ihambisana nokubonakala kwendiza ekhanyayo engemuva omnyama, ongashintshi umbala wayo ngaphansi kwanoma yiziphi izimo. Isici esinjalo, ngokuphambene ne "iphuzu elimnyama", ungazama ukulungisa futhi ekhaya ngosizo oluthile lokuhlukumeza ngokomzimba noma uhlelo.

Kumele kuqashelwe ukuthi abakhiqizi abahamba phambili bezwe manje sebebeka izindinganiso ezikhethekile ezivumela inombolo ethile yamaphikseli angalungile kuma- matrixes abaqaphi bamazinga ahlukene. Lokhu kubalulekile, okokuqala, ukuthi iphesenti lokulahla phakathi kwamatrices esebenza ngamakristali amanzi aphakeme kakhulu. Le nuance kufanele inakekelwe lapho kwenzeka ukuthi uxhumane nesitolo sokulungisa sewaranti. Itafula lamaphikseli anembile alamukelekile afakwe ejwayelekile, ebizwa ngokuthi "ISO-13406". Ingatholakala kalula kwi-intanethi kumasayithi wabakhiqizi abaningi abaholayo bama-LCD abaqaphi.

Abasebenzisi abaningi bavame ukubuza umbuzo: kunzima kanjani ukubona amaphikseli aphukile ngamehlo? Akungabazeki ukuyiphendula ngokungahleleki. Lokhu kungenxa yokuthi uma uthengisa umqapha, abathengisi bavame ukusikhombisa ngokukhanyayo, ukushintsha izithombe, kungakuvumeli ukuthi ubuke kahle ukuboniswa ngezizinda ezihlukene ze- monophonic. Isibonelo, kwenzeka ukuthi iphutha elibomvu lombala obomvu lingabonakala kuphela esizinda esibuhlaza, futhi ngisho nangomthunzi othize. Ngakho-ke, kufanele uhlole ukuthenga kwakho ngokucophelela. Lokhu kungenziwa ngosizo lwezinhlelo ezikhethekile. Enye yezinsiza ezinjalo ezinhle kakhulu yi-Nokia Monitor Test, okuvumela ukuba uhlole umlenze weziphambeko ezihlukahlukene, ukufundeka, ama-piire kanye nama-pixel awonakele.

Ungakhohlwa ukuthi okuthiwa unamathela amaphikseli aphukile (hhayi amachashazi amnyama, nombala), ungazama "ukwelapha" ekhaya. Ngenxa yalokhu ungasebenzisa kokubili izinhlelo ezikhethekile (enye yezinsiza ezinjalo ezibizwa ngokuthi "ScreenFix Deluxe") noma zama ukusikhipha endaweni engalungile yesiboniso nge-swab yekotini. Into eyinhloko, phakathi nalokhu "ukusikhipha" akufanele ukwedlulele, njengethuba lokulimaza ukuboniswa noma ukugqoka kwakhe okubukeka kunzima kakhulu.
