ʻAlohilohi LED: Hōʻike maʻamau ka ʻōlinolino o kahi kukui-emitting diode (LED) i ka ikaika ʻālohilohi, ana ʻia ma ka candela (cd). 1000 μCd (microcandela)=1 mcd (millicandela), 1000 mcd=1 cd. He 500 μCd - 50 mcd ka nui o ka malamalama o ke kukui o loko ho'okahi, oiai he 100 mcd - 1000 mcd ka nui o ka malamalama o ka LED waho ho'okahi, a ma luna o 1000 mcd.
Nā ʻĀpana Pika LED: Ua hoʻonohonoho ʻia nā LED ma nā matrices a i ʻole nā ʻāpana a i hana mua ʻia i loko o nā modula -maʻamau. Loaʻa nā modula hōʻike i loko maʻamau i nā modules 8x8 pixel a me nā modula kikohoʻe 7-segment. Loaʻa nā modula pixel hōʻike waho ma 4x4, 8x8, a me 8x16 kikoʻī pika. No ka mea, ʻo kēlā me kēia pika i loko o kahi hōʻike waho he ʻelua a ʻoi aʻe paha nā pūʻulu LED, ua kapa ʻia lākou he pūʻulu modules.
Nā Pika a me ka Anawaena Pika: Ua kapa ʻia kēlā me kēia kukui LED hiki ke hoʻopaʻa ʻia -hui ( kiko) i loko o kahi hōʻike LED he pika (a i ʻole cell pixel). ʻO ke anawaena pika (∮) e pili ana i ke anawaena o kēlā me kēia pika, ana ʻia i nā millimeters.
No nā hōʻike i loko, hoʻohana mau ʻia kahi LED hoʻokahi, a he ʻano pōʻai. ʻO nā anawaena pixel maʻamau no nā hōʻike i loko o ka ∮3.0, ∮3.75, ∮5.0, a me ∮8.0, me ∮3.75 a me ∮5.0 ka mea maʻamau.
I loko o nā kaiapuni waho, e hoʻomaikaʻi i ka mālamalama a hoʻonui i ka mamao o ka nānā ʻana, aia i loko o kahi pixel ʻelua a ʻoi aʻe nā LED i hui pū ʻia. No ka mea, ʻaʻole pōʻai puni nā LED huipuʻu, ua hōʻike pinepine ʻia ke anawaena pika no nā hōʻike waho ma ke ʻano he awelika ʻokoʻa ma waena o nā pika: □10, □11.5, □16, □22, □25.
Ke kiko kiko, ka nui pika, a me ka mana ʻike: ʻO ke kikowaena -a-ka mamao waena a i ʻole ke kiko kiko o ʻelua pika ma kahi hōʻike LED; ua kapa ʻia ka helu o nā pika ma kēlā me kēia ʻāpana ʻāpana; ua kapa ʻia ka nui o nā mea i hōʻike ʻia ma kēlā me kēia ʻāpana ʻāpana. Hōʻike maoli kēia mau huaʻōlelo ʻekolu i ka manaʻo like: hōʻike ka pixel pitch e like me ka mamao ma waena o nā pika ʻelua; ʻO ka pixel pitch a me ka pixel density ka waiwai kino o ka pale hōʻike. ʻO ka mana ʻike ka ʻāpana helu o ka ʻike e lawe ana i ka hiki o ka pixel density.
ʻOi aku ka liʻiliʻi o ka pixel pitch, ʻoi aku ka kiʻekiʻe o ka pixel density, ʻoi aku ka nui o ka hiki ke ʻike, a ʻoi aku ka kokoke i ka mamao nānā kūpono.
ʻO ka nui o ka pixel pitch, ʻoi aku ka haʻahaʻa o ka pixel density, ʻoi aku ka liʻiliʻi o ka ʻike ʻike, a ʻoi aku ka mamao o ka nānā pono ʻana.
Hoʻoholo: Ua kapa ʻia ka helu o nā lālani a me nā kolamu o nā pika ma kahi pale hōʻike LED. ʻO ka Resolution ka huina o nā pika ma ka pale, kahi e hoʻoholo ai i ka hiki ke ʻike o ka pale hōʻike.
Hōʻike Hōʻike Hōʻike Hōʻikeʻike: Ua kūkulu ʻia kahi pale hōʻike LED ma o ka hui ʻana i nā modula pixel LED i loko o kahi matrix e like me nā pono maoli, me nā kaʻa kaʻa kaʻa i hoʻolaʻa ʻia, DC regulated power supply, software, frames, and external decors.
'Ahinahinahina: 'O ke ki'eki'e o ka ho'ololi 'ālohilohi o kahi pika. He 8 a 12 mau pae hina hina ke kala kumu. No ka laʻana, inā he 256 pae hina hina kēlā me kēia waihoʻoluʻu kumu, hiki i ka pale waihoʻoluʻu -lua-ke hōʻike i 256 × 256=64k kala, a ua kapa ʻia hoʻi he pale hōʻike 256 kala.
