1. He aha ke LED?
ʻO LED ka pōkole o ka light emitting diode. ʻO ke kumu o ka ʻenehana luminescence LED ʻo ia kekahi mau mea semiconductor e hoʻokuʻu i ka mālamalama o kahi lōʻihi nalu i ka wā e hoʻohana ʻia ai kēia manawa. He kiʻekiʻe loa kēia ʻano uila i ka hoʻololi ʻana i ka māmā. Hiki ke hana ʻia nā lāʻau kemika like ʻole ma nā mea i hoʻohana ʻia no ka loaʻa ʻana o nā ʻōlinolino like ʻole. A me ka nānā ʻana i ke kihi LED. He pale ia e hōʻike ana i nā kikokikona, nā kiʻi, nā kiʻi, nā animation, nā huaʻōlelo makeke, nā wikiō, nā hōʻailona wikiō a me nā ʻike ʻē aʻe ma o ka hoʻomalu ʻana i ke ʻano hōʻike o nā semiconductor light-emitting diodes.
2. ʻO nā pale hōʻike LED e loaʻa i kēia mau ʻano.
Hōʻike LED kala piha . Kapa ʻia ka waihoʻoluʻu piha ʻekolu kala kumu, ʻo ka ʻāpana hōʻike liʻiliʻi loa i haku ʻia me nā waihoʻoluʻu kumu ʻekolu o ka ʻulaʻula, ʻōmaʻomaʻo, a me ka uliuli. Hoʻohana nui ʻia ka pale LED piha i nā mokulele, nā kahua kaʻaahi, nā hale kiʻiʻoniʻoni, nā hale kūʻai a me nā pae.
Hōʻike LED waihoʻoluʻu pālua. He ʻulaʻula & ʻōmaʻomaʻo, ʻulaʻula & ʻulaʻula. Ma waena o lākou, ʻulaʻula & ʻōmaʻomaʻo ka mea maʻamau. Hoʻohana nui ʻia nā hōʻike ʻelua kala i ke kālā, kelepona, halemai, palekana lehulehu, nā hale kūʻai kūʻai, kālā a me ka ʻauhau.
Hōʻike LED hoʻokahi. He ʻulaʻula, melemele, ʻōmaʻomaʻo, uliuli, keʻokeʻo. Hoʻohana nui ʻia ka hōʻike LED kala hoʻokahi i nā paka, nā wahi kaʻa a me nā hale kūʻai kūʻai.
Me ka hoʻomaikaʻi ʻana o ka nohona, ke hoʻomau nei ka maʻi o ka poʻe. Ua hoʻololi mālie ʻia nā hōʻike LED kala hoʻokahi a me nā waihoʻoluʻu ʻelua e nā hōʻike LED kala piha.
3. ʻO ka haku mele kumu o ka hōʻike.
Hoʻokumu ʻia ka pale hōʻike LED me nā keʻena LED (hiki ke hoʻopili ʻia) a me nā kāleka hoʻokele (kāleka hoʻouna a me ke kāleka loaʻa). No laila, hiki i ka mea hoʻoponopono nui kūpono a me nā keʻena LED ke hana i nā hōʻike LED nui ʻē aʻe e hoʻokō i nā pono o nā kaiapuni like ʻole a me nā koi hōʻike like ʻole.
4. Nā palena laulā LED pale.
ʻekahi. Nā hōʻailona kino
Pikika pitch
Ka mamao ma waena o nā kikowaena o nā pika pili. (Uni: mm)
ʻO ka mānoanoa
Ka helu o nā pika ma kēlā me kēia ʻāpana ʻāpana (hui: nā kiko/m2). Aia kekahi pilina helu ma waena o ka helu o nā pika a me ka mamao ma waena o nā pika.
ʻO ke kumu helu helu, ʻano nui = (1000/pixel kikowaena mamao).
ʻO ke kiʻekiʻe o ka mānoanoa o kaHōʻike LED, ʻoi aku ka maopopo o ke kiʻi a me ka liʻiliʻi o ka mamao nānā maikaʻi loa.
Palahalaha
ʻO ka wehe ʻole ʻana o nā pika a me nā modula LED i ka wā e haku ai i ka pale hōʻike LED. ʻAʻole maʻalahi ka palahalaha maikaʻi o ka pale hōʻike LED e hoʻohālikelike i ke kala o ka pale LED i ka nānā ʻana.
ʻelua. Nā hōʻailona hana uila
ʻAhinahina hina
ʻO ke kiʻekiʻe o ka mālamalama e hiki ke hoʻokaʻawale ʻia mai ka pōʻeleʻele a hiki i ka ʻoi loa i ka pae like o ka mālamalama o ka hōʻike LED. Kapa ʻia ka unahi hina a i ʻole ka unahi hina, e pili ana i ke degere o ka ʻōlinolino. No ka ʻenehana hōʻike kikohoʻe, ʻo ka grayscale ke kumu hoʻoholo no ka helu o nā kala i hōʻike ʻia. ʻO ka mea maʻamau, ʻoi aku ka kiʻekiʻe o ka pae hina, ʻoi aku ka momona o nā kala i hōʻike ʻia, ʻoi aku ka maʻalahi o ke kiʻi, a ʻoi aku ka maʻalahi o ka haʻi ʻana i nā kikoʻī waiwai.
Aia ka pae hina i nā bit huli A/D o ka ʻōnaehana. Hoʻokaʻawale maʻamau i ʻaʻohe grayscale, 8, 16, 32, 64, 128, 256 pae a me nā mea ʻē aʻe, ʻoi aku ka kiʻekiʻe o ke kiʻekiʻe hina o ka hōʻike LED, ʻoi aku ka momona o ka waihoʻoluʻu, a me ke kala ʻoi aku ka mālamalama.
I kēia manawa, hoʻohana nui ka hōʻike LED i kahi ʻōnaehana hana 8-bit, ʻo ia hoʻi, 256 (28) mau pae hina. ʻO ka ʻike maʻalahi he 256 mau hoʻololi ʻana mai ka ʻeleʻele a keʻokeʻo. Me ka hoʻohana ʻana i nā kala kumu ʻekolu o RGB hiki ke hana i nā kala 256×256×256=16777216. ʻO ia ka mea maʻamau i kapa ʻia he 16 mega kala.
Hoʻohou i ka pinepine o ka pahu
Hōʻike LED hōʻike hōʻike hōʻike ʻike ʻike i ka pinepine.
ʻO ka maʻamau, ʻo ia ka 25Hz, 30Hz, 50Hz, 60Hz, a pēlā aku. ʻO ke kiʻekiʻe o ka hoʻololi ʻana o ke kiʻi, ʻoi aku ka maikaʻi o ka hoʻomau ʻana o ke kiʻi i hoʻololi ʻia.
Hoʻohou pinepine
Hōʻike ka hōʻike LED i ka helu o nā manawa i hōʻike pinepine ʻia ka ʻikepili i kēlā me kēia kekona.
ʻO ka maʻamau ʻo 960Hz, 1920Hz, 3840Hz, etc. ʻO ke kiʻekiʻe o ka hoʻomaha hou, ʻoi aku ka paʻa o ka hōʻike kiʻi. Ke paʻi kiʻi, ʻokoʻa ka nui o ka hōʻano hou ʻana.
5. Hōʻike pūnaewele
ʻO ka ʻōnaehana wikiō LED he ʻekolu ʻāpana, ke kumu hōʻailona, ka ʻōnaehana mana a me ka hōʻike LED.
ʻO ka hana nui o ka ʻōnaehana mana ka hōʻailona hōʻailona, ka hoʻololi ʻana, ke kaʻina hana, ka hoʻouna ʻana a me ka mana kiʻi.
Hōʻike ka pale Led i ka ʻike o ke kumu hōʻailona.
