Uhlelo ukuhlola i-TV ukuze Amaphikseli efile. Kanjani ukuba angaweli umkhiqizo yayingaphelele?

Naphezu kweqiniso lokuthi wonke unyaka LCD ubuchwepheshe TV is njalo ngcono, ingozi ukuthenga TV engaphelele enamaphikiseli ezimbi sisekhona.
Yingakho ngaphambi idili kufanele kube ukuxilonga plasma isibonisi yokubakhona "lezimanga" enjalo. Futhi sibheka namuhla, okuyinto uhlelo ukuhlola i-TV ukuze Amaphikseli efile nokuthi ingasetshenziswa.

A amazwi ambalwa mayelana Amaphikseli

I-pixel elingu - iyona into encane kakhulu noma ukubonisa digital isithombe-matrix. Kuyinto into efuna ngiyinake ngokuphelele isiyingi (ngokuvamile wamaqhuqhuva) ukuma. It pixels yakha isithombe ku qapha noma i-TV.

Inqubo langempela yokukhiqiza plasma izikrini iyinkimbinkimbi futhi kukhathaza, kudinga ukunemba kwawo kanye amathuluzi ezibizayo. LCDs asetshenziswa kumadivayisi cishe zonke digital. Kungaba amakhamera, omakhalekhukhwini, amakhompyutha notebook, Abaqaphi for PC, TV namatilosi.

zinhlayiya

Isisekelo-plasma TV kanye LCD Abaqaphi kukhona zinhlayiya ketshezi. Badabula ukukhanya, okuyinto ngalesosikhathi khiqiza isithombe. Ngokuvamile olwelwesini iphaneli LCD is ezenziwe ngengilazi. Ngakho phakathi izihlungi polarizing futhi iphaneli ibekwe nomzimba omncane ifilimu Transistor, futhi ungqimba amakristalu okukumoduli kwasemuva. Lesi sakamuva kungaba posterior, futhi lateral. Phakathi nomsebenzi we-TV ngokusebenzisa ungqimba crystal sihamba ekukhanyeni okuyinto kweso iguqulwe ukuze isithombe sokugcina.

subpixels

Sam kwe-pixel siqukethe sub-Amaphikseli eziningana (blue, oluhlaza futhi abomvu). Ngosizo lezi esibukweni LCD ungakwazi ukuhlukanisa izigidi ezihlukahlukene imibala kanye shades, crystal-molecule liziphatha njengengxenye into ewuketshezi okungukuthi njalo kunyakaza.

Xilonga hlelo ngoba Amaphikseli efile ku-TV yakho

Okwamanje, kukhona amathuluzi amabili ezidume kakhulu Ihlahlubo ukuhlolwa LCD ekhombisa for Amaphikseli "ufile":

1. TFTTest.
2. DeadPixelTester.

Kulula kakhulu ukuzisebenzisa. Ngezansi, sichaza indlela TV kukhona isheke ku pixels engaphelele kusukela induku kokubili izinhlelo.

Ngakho, siba drive flash futhi TFTTest Umbuso indawo. Okokuqala, udinga ukubhala isofthiwe ayinkimbinkimbi adingekayo. Kufanele zihlanganisa kokubili uhlelo uqobo, futhi ifayela ehlukile iqoqo umbala gradients ligcwale isinqumo 1920 x 1080 Amaphikseli. Ungalanda futhi iqoqo amavidiyo, ngosizo okuyinto ungabona kanjani ithelevishini ithola bese ubonisa isithombe 3D kanye nekhwalithi ukuhumusha (100 kuya ku-800 Hertz).

Ngokulandelayo, ukufaka USB flash drive ku-USB-port ku-TV yakho. I-control unit ungene imenyu bese uxhuma idrayivu. Okulandelayo, khetha i- umbukeli isithombe, ngokukhetha pre-echaziwe umbala igcwalisa. Ngokuvamile ezinqolobaneni sise 9 igcwalisa enjalo ngemibala ophuzi, omnyama, emhlophe, oluhlaza kanye nezinye. Qalisa Umbuso indawo bese ubuyekeze zonke izithombe. Uma isibonisi LCD enesici, siyibuka ngqo esikrinini - bayoba umthunzi ezahlukene kusukela yokugcwalisa isizinda jikelele (noma izothola ngokuzenzakalela uhlelo TV ukuhlola Amaphikseli efile). Kuyinto uyelulekwa ukuhlola ikhwalithi umsindo yakhiqizwa kanye nalokho yezithombe ukujula. Ngakho ungakwazi ukunquma ngokunembile lokhu ithelevishini olungaphelele noma cha.

Uhlelo ukuhlola TV ku Amaphikseli efile DeadPixelTester wawuklanyelwe nokuba ukuhlola LCD zesikrini. Ngenxa wakhe, ungagqamisa yiziphi izindawo osolisayo kwesikrini nganoma iyiphi eminye imibala Uhlelo eziphakanyisiwe. Ukuze lolu hlelo ukuhlola TV ku Amaphikseli efile kuzodinga ukuthi akhethe noma iyiphi umbala oyithandayo bese uhlole izinga ukubonisa kuyo yonke ukubonisa ndawo. Uma i-pixel ye efile kutholakala, ungaya iwindi nge 5 imibala eyisisekelo. Ngakho-ke ngeke ukuhlola kabanzi isayithi osolisayo.

Ingakanani isheke oluphrofeshinali ngobugebengu TV Amaphikseli

Okumangazayo ukuthi, kodwa electronics ezitolo bangakunikeza ukuxilongwa zochwepheshe TV ukukhubazeka okunjalo. Akukho lutho ku akusiyo ehlukile - zonke izenzo zawo zifana wenze ngezandla zakho. Nokho, ukuze lokhu wena kuzodinga ruble 600 1000. Ukuze siqinisekise ezimele njengoba udinga kuphela ye-USB flash drive kanye nokufinyelela ku-intanethi, lapho ungalanda Izinsiza ezidingekayo bese ugcwalisa imibala.

Amaphikseli Dead - lokhu kuyinto evamile noma cha

Eqinisweni, abakhiqizi avunyelwe emakethe TV zinokukhubazeka Nokho, ingqondo 1 ayisigidi akumelwe beqa imingcele ethile. Liquid crystal display kukhona ekilasini lokuqala ayivumeli khona ukukhubazeka okunjalo. Ngokuvamile, lena onobuhle eqolo futhi ezingavamile TV ukuthi akuzona ethandwa kakhulu futhi e funa ezimakethe zomhlaba. Ikilasi yesibili ivumela, hhayi ukukhubazeka engaphezu kwemibili uhlobo mina kanti abayizigidi II komunye pixels. Lesi sigaba ithandwa kakhulu emakethe Russian. Ekilasini lesithathu ivumela khona kuze 5 Amaphikseli kwabafileyo mina namabanga II no-50 grade III. Eyesine ingaqukatha izinhlobo 500 ezahlukene ukukhubazeka, kodwa ma-TV kuze bahlangana Russian electronics ezitolo.

Ngakho esiphethweni kanjani ukukhiqiza test wesibuko Amaphikseli efile, kanye Bangaki abantu abafa ngenxa kokuqukethwe yayo ezinhlobeni ezihlukene TV.
