Taro na Fasaha Game da Mahimmancin Pixel Pitch, Duban nesa da Girman Nuni na LED.
Gilashin bangon bidiyo na LED yana ci gaba da canza wurare a duniya.
Ikklisiya, makarantu, ofisoshi, filayen jirgin sama da dillalai suna haifar da ƙwaƙƙwaran, kuzari, abubuwan tunawa a wurare daban-daban na ciki da waje.
Idan kuna la'akari da nunin LED, ɗayan mafi mahimmancin zaɓinku shine zaɓin pixel pitch, amma kuna iya yin mamaki, menene pixel pitch? Ta yaya farar pixel ke shafar farashi? Menene mahimman la'akari yayin zabar farar pixel?
Anan don yanzu, BariYonwaytechDubi yadda zaku iya yin zaɓin filin pixel da ya dace don kuLED video bangoaikin.
Da farko, menene pixel pitchs?
Ana haɗa bangon LED tare da bangarorin LED, wanda a cikin su ya ƙunshi nau'ikan LED masu yawa. Waɗannan nau'ikan LED suna ɗauke da gungu na LED ko fakitin LED, watau ja, shuɗi da koren haske emitting diodes (LEDs) waɗanda aka haɗa su cikin pixels.
Fitar pixel ita ce tazara ta tsakiya zuwa tsakiya tsakanin pixels biyu, yawanci ana auna ta cikin millimeters.
Idan kana da farar pixel 10mm, yana nufin cewa nisa daga tsakiyar pixel ɗaya zuwa tsakiyar pixel ɗin da ke kusa shine milimita 10.
Abu na biyu, Menene tasirin tasirin pixel akan ingancin hoton LED?
Filin Pixel yana ƙayyade ƙudurin nunin LED, mafi ƙarancin nisa kallo da mafi kyawun nisan kallon allo na LED.
Karamin farar pixel, ƙarin pixel da sakamako a cikin ƙarin cikakkun bayanai da ingancin hoto mafi girma.
Don haka idan kuna buƙatar nuna hotuna masu ƙarfi ko bidiyo akan nunin ku, kuna buƙatar nunin LED tare da ƙaramin pixel farar.
Hoton da ke gaba yana nuna tasirin tasirin pixel akan ingancin hoto, ƙaramin girman pixel yana kaiwa zuwa mafi girma ƙuduri da ƙarin cikakkun bayanai.
Na uku, Ya kamata a yi la'akari da nisa na kallo lokacin da kuke gina kyakkyawar nunin jagora.
Pixel pitch yana ƙayyade ƙimar pixel kai tsaye-yawan pixels a cikin wani yanki na allo-kuma yawan pixels kai tsaye yana ƙayyade nisa da aka ba da shawarar - nisa daga bangon bidiyo mai kallo ya kamata ya kasance yana da gamsasshen gogewar kallo.
Mafi kyawun, ko ƙarami, farar, mafi kusancin nisan kallo karɓuwa.
Girman filin wasa, mafi nisa da mai kallo yakamata ya kasance.
Pitch shima yana tasiri kai tsaye akan farashi, amma babban pixel a cikin ƙaramin allo mai jagora da tsayin kallo ko babban nunin jagora amma gajeriyar nisa duka biyu ba za su iya fitar da kyakkyawan aikin bidiyo ba.
Don zaɓar mafi kyawun fitin pixel yakamata a yi la'akari da abubuwa biyu, nisan kallo da ƙudurin hoton da ake buƙata.
Ƙananan filayen pixel sun fi kyau koyaushe kuma suna sadar da ku mafi kyawun hoto amma, yana da ƙari.
Kuna iya rage farashin siyan nunin LED ta amfani da farar pixel mafi girma kuma har yanzu kuna da ingancin hoto iri ɗaya idan nisan kallo ya fi tsayin kallo mafi kyau.
Mafi kyawun nisa na kallon pixel pitch shine nisa da idanunku ba za su iya zuwa ga gibba tsakanin pixel ba kuma idan kun yi nisa.
Hanyoyin lissafi na zaɓin nunin LED masu dacewa.
Kamar yadda aka bayyana a sama, pixel pitch babban la'akari ne ga wannan tsari. Yana tafiya tare da wasu dalilai kamar girman nuni, nisa kallo, yanayin haske na yanayi, yanayin yanayi da kariyar danshi, kafofin watsa labarai masu gasa, aikin saƙo, ingancin hoto da ƙari mai yawa.
Abubuwan nunin LED da aka tura da kyau suna da damar haɓaka zirga-zirga, haɓaka haɗin gwiwar masu sauraro, da haɓaka ƙwarewar abokin ciniki. Amma fahimtar yadda fasaha za ta yi tasiri ga mai kallo da kuma layinka na kasa kafin zuba jari zai iya ba ka damar yanke shawara mafi kyau don takamaiman bukatunka da kasafin kuɗi.
Ƙimar ƙayyadaddun ƙayyadaddun ƙayyadaddun ƙididdiga don bayanin ku kamar ƙasa:
Mafi ƙarancin nisa kallo:
Nuni na LED nesa nesa (M) = pixel Pitch (mm) x1000/1000
Mafi kyawun nisa kallo:
LED nuni mafi kyawun nisa kallo (M) = Pixel Pitch (mm) x 3000~ pixel Pitch (mm) / 1000
Mafi nisa kallo:
Mafi nisa (M) = Tsawon allo na LED (m) x sau 30
Don haka alal misali, nunin jagorar P10 a cikin nisa 10m da tsayin 5m, mafi kyawun nisan kallo ya wuce 10m, amma matsakaicin nisan kallo shine mita 150.
Idan ba ku da tabbas game da filin pixel da ya dace don amfani da aikin LED ɗin ku, TUNTUBEYonwaytechNuni LED yanzu kuma za mu nuna muku hanyar da ta dace. Duba sau da yawa don ƙarin batutuwa masu taimako.
