Pixels zosalongosoka pa polojekiti ndi. Kufotokozera za vuto ndi njira kulimbana izo.

Masiku ano, aliyense wosuta a katundu wamakono komanso zida kompyuta, mawu akuti "akufa pixels" kanthu koma mutu ndi vuto lokhala wosasangalala zoipa, osati zimayambitsa. Koma kodi izi makamaka ndi momwe Tsoka ndi, kuti "odala" mwini luso ndi pixels zomwezi kumenyedwa?

Pakuti starters, tiyeni tiwone, ma TV masiku ano oyang'anira ntchito pa mfundo. Phula kusonyezedwa galasi apange fano ndi kuchuluka kwa mfundo zomwe zimatchedwa pixels. Pamene kusintha mtundu wawo, fano chophimba nazonso kusintha, ndipo ife tikhoza kuwona chithunzi panopa mfundo zimenezi. Mu oyang'anira masiku ano anaika masanjidwewo, otchedwa yogwira - momwemo kasamalidwe aliyense mapikiselo limafanana ndi limodzi woonda filimu transistor (nchifukwa chake zowonetsera amenewa amatchedwa TFT, ku England Pamtendere Film Transistor). Ngati mmodzi wa transistors izi chifukwa ena amalephera, ife tingathe kuona chodabwitsa, wotchedwa akufa mapikiselo pa polojekiti ndi.

Chifukwa wonongeka luso transistor ndi, mfundo zimenezi sasintha mtundu awo pa nthawi ya chophimba fano ndi kusintha ndi wakuda dontho. Ngakhale ayenera adzanyamula kukumbukira kuti pixels akufa sadziwa wakuda kokha - pa wakuda maziko ndi mfundo zambiri woyera, ndipo pali wofiira, buluu ndi pixels wobiriwira ndi wolakwika. Munthu wolephera mu nthawi yathu angathe kudzudzulidwa ndi msonkhano katswiri. Kuti tichite zimenezi, muyenera m'malo analephera transistor lolingana, ndipo kachiwiri adzatha kuchita ntchito zawo.

Koma izo zimachitika kuti pixels akufa pa zenera sumangoyambika chifukwa kulephera kwa transistor, ndi kuyamika otchedwa pixels Anapitirizabe. Kawirikawiri kupanikizana limodzi ndi maonekedwe a madontho kuwala pa maziko mdima, amene sasintha mtundu zivute zitani. Chotero chilema, monga kuyenera "mawanga akuda", mungathe kuyesa kukonza ndi kunyumba ndi thandizo la ena mpheto thupi kapena mapulogalamu.

Iwo ayenera kukumbukira kuti opanga ŵa panopa malamulo apadera kuti kulola ena chiwerengero cha pixels zolakwika mawerengetsedwe oyang'anira mfundo zosiyanasiyana. Ichi ndi chifukwa yaikulu chakuti kuchuluka kwa ukwati pakati mawerengetsedwe zikugwira ntchito pa timibulu madzi, si mkulu. nuance uyu ayenera kulabadira ngati mukupita ntchito kwa kukonza pansi chitsimikizo. Table kololeka zosalongosoka pixels m'gulu muyezo wotchedwa «ISO-13406." Izo zikhoza pa Intaneti pa ambiri opanga yaikulu ya oyang'anira LCD.

anthu ambiri nthawi zambiri funso n'lakuti: n'kovuta kuona pixels akufa ndi apoyera? Yankhani bwino ndi chodziwikiratu kuti apambane. Ichi ndi chifukwa chakuti pamene inu kugula mavenda ndi polojekiti zambiri tionetseni yowala kusintha images, osalola potero tayang'anani pa kuwonetsera mu zosiyanasiyana anakula kumveka. Mwachitsanzo, zimachitika kuti mfundo zosalongosoka ofiira Tingaone kokha pa maziko zobiriwira, kenako yekha pansi hue ena. Choncho, fufuzani kugula anu kukhala osamala kwambiri. Izi zikhoza kuchitika mothandizidwa ndi zochitika zapadera. Imodzi yabwino ya zida izi ndi «Nokia Monitor Mayeso», amene amalola pa polojekiti kuti ayese pamaso pa zofooka zosiyanasiyana, aziwakonda, moire ndi pixels zowonongeka.

Musaiwale kuti otchedwa pixels akufa munakhala (palibe madontho akuda, ndi mtundu), mungayesere kuti "mankhwala" kunyumba. Kuti tichite zimenezi, mukhoza kugwiritsa ntchito kapena mapulogalamu apadera (imodzi yabwino ya zipangizo amatchedwa «ScreenFix Deluxe») kapena kuyesa promassirovat zosalongosoka anasonyeza m'dera ndi swab thonje. Chinthu chachikulu ichi "kutikita" si overdo izo, chifukwa mwayi kuwononga dzikoli anasonyeza kapena ❖ kuyanika odana chimawala waukulu ndithu.
