Pehea e kūʻai ai i loko o ka Led hōʻike?

Hōʻike ʻia ʻo LED ma ke ʻano he mea hana media kaulana, i makemake nui ʻia e ka hapa nui o nā mea hoʻohana. Hōʻike LED ma ke ʻano o nā kiʻi, animation, wikiō, manawa maoli, synchronous, hoʻokuʻu maopopo ʻia o nā ʻike like ʻole. ʻAʻole hiki ke hoʻohana wale ʻia no ka kaiapuni o loko e hiki ke hoʻohana ʻia no ka kaiapuni o waho, me ka projector, ka pā TV, ʻaʻole hiki ke hoʻohālikelike ʻia ka pale LCD me nā pono.

Ma ke alo o ka laulā o ka LED hōʻike, he nui nā mea kūʻai mai i ke kuai ana i ka LED hōʻike i ka manawa o ke ala ole e hoʻomaka. ʻO kēia ka hoʻolauna pōkole i ka hōʻike LED i loko maʻamau, ke manaʻo nei au e kōkua i ke kūʻai ʻana i ka hōʻike LED:

1、Hoʻohālike Hoʻohālike Led i loko
Loaʻa ka hōʻike LED i lokoliʻiliʻi pitch alakaʻi hōʻike, P2, P2.5, P3, P4 hōʻike LED kala piha. ʻO ka mea nui e like me ka pitch point hōʻike LED no ka hoʻohālikelike ʻana, ʻo P2.5 ka mamao ma waena o ʻelua mau pika he 2.5mm, ʻo P3 ka 3mm a pēlā aku. No laila, ʻaʻole like ka spacing kiko, ʻaʻole like kēlā me kēia mika square i ka kiko pixel, no laila ʻaʻole like kā mākou akaka. ʻOi aku ka liʻiliʻi o ke kiko kiko, ʻoi aku ka nui o nā kiko pixel i kēlā me kēia ʻāpana, ʻoi aku ka kiʻekiʻe o ka mālamalama.

2、Kaiapuni hoʻokomo
Kaiapuni hoʻonohonoho: ʻo ke kaiapuni hoʻonohonoho ka noʻonoʻo mua i kā mākou koho ʻana i ka hōʻike LED. Hoʻokomo ʻia kā mākou pale LED i loko o ke keʻena, a i ʻole i hoʻokomo ʻia i loko o ka lumi hālāwai, a i ʻole i kau ʻia ma kakahua; he hoʻonohonoho paʻa, a i ʻole ka pono no ka hoʻokomo kelepona.

3、Ka mamao nana kokoke loa
He aha ka mamao makaʻala kokoke loa, ʻo ia hoʻi, ke kū nei mākou i ka pale ma kahi mau mika mai ka ʻike. E like me kā mākou P2.5 kokoke loa i ka nānā ʻana ma 2.5 mika, P3 kokoke loa i ka nānā ʻana ma 3 mika, e like me ka inoa e hōʻike nei, P ma hope o ka helu i hoʻohui ʻia i kā mākou hōʻike hōʻike LED, e hōʻike ana hoʻi i kā mākou mamao nānā kokoke loa. No laila, i ke koho ʻana i nā hiʻohiʻona hōʻike LED i loko, pono paha e koho ʻia ka mamao nānā hou loa, i hiki iā mākou ke koho i kahi kumu hoʻohālike maikaʻi.

4、Ka wahi pale
ʻO ka nui o ka pale, a me kā mākou kūʻai ʻana i loko o ka pale LED i pili pū kekahi. Ma ka laulā, inā ʻaʻole ʻoi aku ka nui o ka pale hōʻike LED i loko o 20 mau mika square, ʻoi aku ka maʻamau e hoʻohana i ke ʻano bracket, inā ʻoi aku ka nui, manaʻo mākou e hoʻohana i ka pahu maʻalahi. Eia kekahi, inā nui ka ʻāpana pale, maʻamau hiki ke hoʻoponopono i nā hemahema o kā mākou mamao nānā hou ma o ka ʻāpana pale, akā ʻoi aku ka maikaʻi ʻaʻole e hoʻoponopono i kēia ala.
