ʻO ke kala a me ka maikaʻi o nā LED e pili ana i nā mea a me nā kaʻina hana i hoʻohana ʻia i kā lākou hana ʻana. ʻO kaʻulaʻula, ka'ōmaʻomaʻo, a me ka uliuli ka mea i hoʻohana nuiʻia. Ma muli o ka hana ʻana o nā hōʻike LED ma ka uila haʻahaʻa (5V wale nō), hiki ke hoʻokuʻu i ke kukui me kahi ʻōlinolino hiki ke hoʻololi ʻia e ka volta (a i ʻole ka manawa), a ʻaʻohe hopena -paʻa, vibration-a he lōʻihi ke ola (100,000 hola), ʻaʻohe ala hōʻike ʻē aʻe e hiki ke hoʻohālikelike i nā hōʻike LED i nā mea hōʻike nui -nui.
ʻO ka pale hōʻikeʻike e hui pū ana i nā LED ʻulaʻula a me ka ʻōmaʻomaʻo ma ke ʻano he pika hoʻokahi, ua kapa ʻia he pale waihoʻoluʻu ʻelua a i ʻole pale waihoʻoluʻu piha-; ʻO ka pale hōʻikeʻike e hui pū ana i nā LED ʻulaʻula, ʻōmaʻomaʻo, a me ka uliuli ma ke ʻano he pika hoʻokahi, ua kapa ʻia he pale kala ʻekolu a i ʻole ka pale kala piha. He 2-20 mm ka nui o nā pale LED o loko, me ka ho'ohana pinepine 'ana i kekahi mau pahu kukui LED e hana ana i nā kala kumu like 'ole i pū'olo pū 'ia. He 8{12}}32 mm ka nui o nā pale LED waho, me kēlā me kēia pika i haku ʻia me kekahi mau LED monochrome. Ua kapa ʻia nā huahana maʻamau i hoʻopau ʻia ʻo pixel tubes; ʻO nā paipu pixel ʻelua waihoʻoluʻu he 2 ʻulaʻula a me 1 ʻōmaʻomaʻo LED, ʻoiai ʻo nā paipu pixel ʻekolu kala he 1 ʻulaʻula, 1 ʻōmaʻomaʻo, a me 1 LED polū.
Inā ho'ohana 'ia nā LED no ka hana 'ana i nā pale kala-lua, 'elua, a i 'ole 'ekolu{1}}kala, pono e ho'ololi 'ia ka 'ōlinolino o kēlā me kēia LED i ho'okahi pika e hō'ike i ke ki'i. Ua kapa ʻia ka maikaʻi o kēia hoʻololi ʻana i ka pae hina hina o ka pale hōʻike. ʻOi ke kiʻekiʻe o ke kiʻekiʻe hina, ʻoi aku ka maʻalahi o ke kiʻi i hōʻike ʻia, ʻoi aku ka momona o nā waihoʻoluʻu, a ʻoi aku ka paʻakikī o ka ʻōnaehana mana hōʻike e pili ana. ʻO ka mea maʻamau, he 256-level grayscale kiʻi ʻoniʻoni loa ka hoʻololi kala, ʻoiai he 16-level grayscale kiʻi i ʻike maopopo loa i nā palena hoʻololi kala. No laila, pono e loaʻa i nā pale LED kala o kēia manawa he 256 a 4096 mau pae hina.
ʻO nā mea luminescent LED i hoʻohana ʻia i nā hōʻike e hele mai i kēia mau ʻano:
Nā kukui LED (a i ʻole nā kukui hoʻokahi): ʻO ka mea maʻamau i haku ʻia me hoʻokahi pahu kukui LED, kahi hōʻike manaʻo, kahi anode metala, a me kahi cathode metala, i hoʻopaʻa ʻia i loko o kahi pūpū epoxy resin me ka hiki ke hōʻiliʻili māmā. Hiki i hoʻokahi a ʻoi aku paha (nā waihoʻoluʻu ʻokoʻa) nā kukui hoʻokahi i kahi pika kumu. Ma muli o ko lākou ʻālohilohi kiʻekiʻe, hoʻohana nui ʻia lākou i nā hōʻike waho.
Nā modules dot matrix LED: Hoʻokumu ʻia me nā ʻāpana he nui i hoʻokumu ʻia i kahi matrix luminescent, i hoʻopili ʻia i loko o kahi pūpū epoxy resin i loko o kahi pūpū plastik. He kūpono no ka holo ʻana i ka lālani a me ke kolamu, e hana maʻalahi i nā hōʻike kiʻekiʻe -a hoʻohana nui ʻia i nā hōʻike i loko.
ʻO nā LED mauna ʻili (a i ʻole nā SMD LED) he mau LED i loko o kahi pūʻolo mauna ʻilikai, kūpono no nā hōʻike kala piha -loko, e ʻae ai i ka mālama ʻana-kahi a me ka lanakila ʻana i nā hopena mosaic.
