Inkqubo ukukhangela TV ukuya pixels abafileyo. Njani ukuba kuwa ngenxa imveliso ephosakeleyo?

Nangona unyaka LCD technology TV qho ukuphucuka, umngcipheko ukuthenga TV esinesiphene nge pixels ezimbi lisekhona.
Kungenxa yoko le nto phambi kokuba deal kufuneka ibe ukuhlola plasma ukubonisa ubukho ezinjalo "izimanga". Kwaye Sijonge namhlanje, nto leyo yinkqubo yokuvavanya TV ukuya pixels abafileyo kwaye zingasetyenziswa njani.

A amagama ambalwa malunga pixels

Pixel - yeyona nto kakhulu encinane okanye ukubonisa umfanekiso matrix lwedijithali. Kuyinto into setyhula epheleleyo (rhoqo uxande) imilo. It pixels uzakhela umfanekiso kwi esweni okanye TV.

Inkqubo kanye ukuvelisa screens plasma unzima kakhulu kwaye onzima, kufuna ngobuciko aphezulu kunye nezixhobo imali eninzi. LCD zisetyenziswa izixhobo kuzo zonke digital. Kunokuba kubakho iikhamera, mobile phones, kweekhompyutha eziphathwayo, amagosa okubeka esweni iimviwo ukuba PC, TV kunye matiloshe.

kwakheka

Isiseko TV plasma kunye esweni LCD zizinto crystals ulwelo. Ke, bayihambahamba ukukhanya, ke yona umfanekiso. Amaxesha amaninzi umaleko olungaphandle yolawulo LCD yenziwe ngeglasi. Ngaloo phakathi izihluzi wokohlula ukuze indawo yolawulo ibekwe a transistor umboniso obhityileyo, kunye umaleko ziikristale kwimodyuli ilayithi. Lo wokugqibela kuba nokuba ngomva, kunye lateral. Ngexesha nokusebenza TV nge yikristale umaleko udlula ukukhanya nto leyo nangoko atshintshelwe kumfanekiso wokugqibela.

subpixels

Sam pixel siquka sub-pixel ezininzi (blue, oluhlaza kunye nobomvu). Ngoncedo ezi LCD wekhusi ungahlula izigidi iintlobo ngeentlobo imibala kunye ezikhanyayo, crystal molecule liziphatha njengenxalenye into engamanzi ukuba usoloko ihamba.

Nokuxilonga program for pixels ofileyo kwi TV yakho

Okwangoku, kukho izixhobo ezimbini ithandwayo moshilongo kunye nokuvavanywa lemiboniso LCD ngenxa pixels "ufile":

1. TFTTest.
2. DeadPixelTester.

Kulula kakhulu ukuba yokuzisebenzisa. Ngezantsi, sichaza indlela TV kukho itsheki phezu pixels ezingasebenzi ukusuka ntonga zombini iinkqubo.

Ngoko ke, siya kuba flash drive kwaye eluncedo TFTTest. Okokuqala, kufuneka ubhale software enzima ezifunekayo. Kufuneka edibanisa zombini inkqubo ngokwawo, kunye ifayile hlukanisa iseti ukuthambeka umbala kwaye Wawuzalisa enesisombululo ka 1920 x 1080 pixels. Uyakwazi nokukhuphela isethi iividiyo, ngoncedo apho ungabona indlela umabonwakude lifumana ezigunyazisiweyo imeji kwifomathi 3D nomgangatho lokunikezelwa (100 ukuya 800 Hertz).

Okulandelayo, faka i USB flash drive kulo USB-izibuko kwi TV yakho. Iyunithi yolawulo iye kule menu uze uqhagamshele drive. Okulandelayo, khetha i ifoto umbukeli, ngokukhetha lenza umbala echazwe-ngaphambili. Ngokufuthi kumathala libekwe ku-9 kuzele ezinjalo nge yellow, abamnyama, abamhlophe, eluhlaza kunye nezinye imibala. Baleka i ezilijelo nayo ngokutsha zonke iifoto. Ukuba isiboniso LCD yesiphako, sibona ngazo ngqo kwi khusi - baya kuba umthunzi ezahlukeneyo ukusuka yokugcwalisa imvelaphi ngokubanzi (okanye uya ibhaqe ngokuzenzekelayo inkqubo TV ukutshekisha pixels kwabafileyo). Uyacetyiswa kwakhona ukuba ukujonga umgangatho isandi iveliswa kwaye umahluko we ubunzulu imifanekiso. Ngoko unako ukugqiba ngokuchanileyo le umabonakude ezineziphene okanye hayi.

Inkqubo ukukhangela TV kwi pixels abafileyo DeadPixelTester yayilwa ukuvavanya izikrini LCD. Ngenxa yakhe, ungenza kugqamisa iindawo bandikrokrele lomkhusane nayiphi na inkqubo imibala ezicetyiswayo. Ukuze le nkqubo lokuvavanya TV kwi pixels abafileyo baya kufuna ukuba ukhethe nawuphi na umbala oyithandayo kwaye ahlole umgangatho ukubonisa on yonke indawo elibonisiweyo. Ukuba pixel abafileyo lafunyanwa isela elo, ungaya kwi window nge-5 imibala ezisisiseko. Ngoko ke uya kuphonononga ngakumbi isiza ekrokrisayo.

Ingaba itsheki elikwinqanaba pixels TV ezaphukileyo

Emangalisayo, kodwa kwiivenkile elektroniki nga zingakunikeza baphethwe ye-TV ukuya ezo ziphene. Kwakungekho nto akukho olwahluke - zonke izenzo ziyafana nezo usenza ngezandla zakho. Nangona kunjalo, kuba oku uya kufuna ukusuka engange-600 ukuya 1000. Zokuqinisekiswa okuzimeleyo njengokuba ufuna kuphela USB flash drive kwaye ukufikelela kwi-Internet, apho unako ukufumana khona eziluncedo eziyimfuneko ugcwalise imibala.

pixels Dead - oku nanjengokwesimo okanye

Enyanisweni, abavelisi bavumelekile ukuba nomabonakude emarikeni kunye iziphene, Noko ke, ingqalelo million 1 ipixels kufuneka beqela imida ethile. Ulwelo crystal displays zezona kwiklasi yokuqala akaphazanyiswa ubukho ezo ziphene. Amaninzi, oku kukho imifuziselo TV ukuba akukho zithandwa kakhulu kwaye ezifunwayo kwimarike yehlabathi eninzi kakhulu yaye kunqabile. Udidi lwesibini ivumela, hayi iziphene ngaphezu ezimbini uhlobo I pixels II ukuya kwesigidi. Esi sigaba ithandwa kakhulu kwi kwimarike Russian. Udidi lwesithathu uvumela ubukho ukuya ku-5 pixels lwabafileyo endimangalelwayo mna kunye grade II-50 kwibanga III. Le yesine kungaba iintlobo ukuya ku-500 ezahlukeneyo iziphene, kodwa ezi nomabonakude de babehlangana kwiivenkile elektroniki Russian.

Ngoko ke ndicinge ukuba aveze indlela uvavanyo nesisitheliso pixels abafileyo, kwakunye noko izinga umxholo kwazo iintlobo ezahlukeneyo TV.
