LED nuni yanayin dubawa da asali aiki ka'idar

Tare da haɓaka fasahar LED, hasken nunin lantarki na LED yana ƙaruwa, kuma girman yana ƙara ƙarami, wanda ke nuna cewa ƙarin nunin lantarki na LED a cikin gida zai zama yanayin gaba ɗaya. Duk da haka, saboda inganta LED haske da pixel yawa ga LED allo iko da drive kuma kawo sabon mafi girma bukatun. A kan allo na cikin gida na gabaɗaya, yanzu ana amfani da hanyar sarrafawa ta gama gari a cikin layuka da ginshiƙan yanayin yanayin sarrafawa, wato, galibi ana kiranta yanayin sikanin, a halin yanzu, yanayin nunin lantarki na LED yana da tsayayyen sikanin da bincike mai ƙarfi. Ana rarraba nau'ikan sikanin tsaye guda biyu zuwa piksels na gaske da kuma a tsaye, ana kuma rarraba sikanin sikandire zuwa hoto na gaske da kuzari.

A cikin nunin lantarki na LED, adadin layuka da aka kunna a lokaci guda da kuma adadin adadin layuka a cikin duka yanki, wanda ake kira yanayin dubawa. Ana kuma raba scanning zuwa 1/2duba, 1/4duba, 1/8duba, 1/16dubada sauransu akan hanyoyin tuki da yawa. Wato nunin ba iri daya bane, to saitin katin karba shima ya banbanta. Idan da farko an yi amfani da katin karɓa a cikin allon dubawa 1/4, yanzu ana amfani da shi a cikin allon tsaye, to nunin da ke kan nuni zai kasance kowane layuka 4 na layi mai haske. Ana iya saita katin karɓa na gabaɗaya, haɗa zuwa katin aikawa, nuni, kwamfuta da sauran manyan na'urori, zaku iya shigar da software masu dacewa akan kwamfutar don saitawa. Don haka a nan ne farkon wanda zai gabatar da yanayin sikanin nunin lantarki na LED da ka'ida.

  • Yanayin sikanin nunin lantarki na LED.

1. Dynamic scanning: tsauri scanning ne daga fitarwa na direban IC zuwa pixel tsakanin aiwatar da "point-to-column" iko, dynamic scanning kula da kewaye ake bukata, da kudin ne m fiye da a tsaye scanning, amma Tasirin nuni ya fi talauci, mafi girman asarar haske.

2. Static scanning: Static scanning ne fitarwa daga direban IC zuwa pixel tsakanin aiwatar da "point-to-point" iko, a tsaye scanning ba ya bukatar iko da'irori, da kudin ne mafi girma fiye da tsauri scanning, amma tasirin nuni yana da kyau, kwanciyar hankali mai kyau, ƙarancin hasarar haske da sauransu.

  • LED lantarki nuni 1/4 scan yanayin aiki manufa:

Yana nufin cewa ana kunna wutar lantarki V1-V4 na kowane layi don 1/4 na lokaci kowanne bisa ga buƙatun sarrafawa a cikin firam 1 na hoto. Amfanin wannan shine cewa halayen nuni na LEDs za a iya amfani da su yadda ya kamata kuma ana iya rage farashin kayan masarufi. Rashin hasara shine kowane layi na LEDs zai iya nuna 1/4 na lokaci kawai a cikin firam 1.

  • Dangane da hanyar rarraba nau'in sikanin nunin lantarki na LED:

1. Yanayin cikin gida mai cikakken launi LED yanayin dubawa na nuni: P4, P5 don 1/16 na yau da kullum, P6, P7.62 don 1 / 8 na yau da kullum.

2. waje cikakken launi LED lantarki nuni yanayin duban allo: P10, P12 don m halin yanzu 1/2, 1/4, P16, P20, P25 ga a tsaye.

3. Single da biyu launi LED lantarki nuni yanayin dubawa ne yafi akai halin yanzu 1/4, m halin yanzu 1/8duba, m halin yanzu 1/16duba.
