Nā Kumu Hōʻike Led

ʻO ka hōʻike LED he hōʻike papa pālahalaha, i haku ʻia me nā panela module LED liʻiliʻi, i hoʻohana ʻia e hōʻike i nā kikokikona, nā kiʻi, nā wikiō, nā hōʻailona wikiō a me nā lako ʻike like ʻole.

Hoʻohana nui ʻia ia no ka hoʻolaha ʻana i loko o waho, hōʻike, pāʻani, hana hope a me nā kumu ʻē aʻe. Hoʻokomo maʻamau i nā wahi pāʻoihana, hale facades, alanui alanui, ākea ākea, ke kahua o loko, nā lumi hālāwai, nā studio, nā hale ʻahaʻaina, nā kikowaena kauoha a me nā wahi ʻē aʻe, e pāʻani i ka hōʻike.

Ⅰ. ke kumu hana o ka hōʻike LED

ʻO ke kumu hana maʻamau o ka hōʻike LED he dynamic scanning. Hoʻokaʻawale ʻia ʻo Dynamic scanning i ka nānā ʻana i ka laina a me ka nānā ʻana i ke kolamu ʻelua ala, ʻo ke ala maʻamau ka nānā ʻana i ka laina. Hoʻokaʻawale ʻia ka nānā ʻana i nā laina i 8 laina scanning a me 16 line scanning.

Ma ka laina scanning mode o ka hana, kēlā me kēia ʻāpana o LED dot matrix piece he set of column drive circuit, column drive circuit e pono e loaʻa kahi latch or shift register, hoʻohana ʻia e laka i ka ʻike e hōʻike ʻia ma ka ʻikepili mode word. Ma ka laina scanning mode o ka hana, ua hui like ka lalani o LED dot-matrix apana o ka inoa like me na pine mana laina ma ka laina, he 8 laina, a pili loa i ke kaapuni laina; Pono e loaʻa i kahi kaapuni kaʻa kaʻa laina ka laka a i ʻole ka papa inoa hoʻololi, i hoʻohana ʻia e laka i ka hōʻailona nānā laina.

Hoʻohana maʻamau ʻia ka mana o ka microcontroller LED hōʻike kolamu kaapuni a me ke kaapuni laina, ʻo ka microcontroller maʻamau ka MCS51 series. Mālama ʻia nā ʻike hōʻike LED ma ke ʻano o ke ʻano huaʻōlelo i ka hoʻomanaʻo ʻikepili waho o ka microcontroller, ʻo ke ʻano huaʻōlelo he helu binary 8-bit.

Ⅱ. ka ʻike kumu o ka hōʻike Led

1, he aha ka LED?

ʻO ka LED he hoʻokoe ʻia o ka diode māmā (LIGHT EMITTING DIODE), ma o ka hoʻonohonoho ʻana o ka diode māmā i haku ʻia me kahi mea hōʻike. Ua ʻōlelo ka ʻoihana hōʻike e pili ana ka LED i ka LED e hiki ke hoʻokuʻu i nā nalu ʻike.

2, he aha ka hōʻike LED?

Ma o kekahi mau ʻano hoʻomalu, ua haku ʻia ke ʻano o nā hāmeʻa LED me ka pale hōʻike.

3, he aha ka module hōʻike LED?

Aia nā kaapuni a me ka hoʻonohonoho hoʻonohonoho e hoʻoholo ai, me nā hana hōʻike, hiki ke ʻike ʻia ma o ka hana hōʻike hōʻike maʻalahi o ka ʻāpana kumu.

4, He aha ke modula hōʻike LED?

Hoʻokumu ʻia me kahi helu o nā pika hōʻike, kūʻokoʻa kūʻokoʻa, hiki ke hana i ka ʻāpana liʻiliʻi o ka hōʻike LED. 8 * 8 maʻamau, 8 * 7, etc.

5. He aha ka pixel pitch (dot pitch)?

ʻO ka mamao waena ma waena o nā pika pili ʻelua, ʻoi aku ka liʻiliʻi o ka pitch, ʻoi aku ka pōkole o ka mamao ʻike. Hoʻopau pinepine ʻia ka ʻoihana i ka P e hōʻike i ke kiko kiko.

6, He aha ka nui o ka pixel?

ʻIke ʻia hoʻi ʻo ke kiko kiko, pili pinepine i ka helu o nā pika i kēlā me kēia mika square ma ka hōʻike.

7, He aha ke kukui uila?

ʻO kahi ʻāpana hōʻike LED i hoʻopuka ʻia e ka ikaika māmā, ʻo ka ʻāpana he CD / square mika, waiho wale ʻia kahi hōʻike mika square i hoʻopuka ʻia e ka ikaika māmā;

8, he aha ka ʻōlinolino o ka hōʻike LED?

Hōʻike ka ʻōlinolino LED i ka hana maʻamau o ka hōʻike, ʻo ka ʻāpana hōʻike o ka nui o ka luminous, ʻo ka ʻāpana he cd / m2 (ʻo ia hoʻi, ehia mau cd o ka nui o ka luminous i kēlā me kēia mika square o ka wahi o ka hōʻike.

11, He aha ka pae hina?

ʻO ka pae hina hina o ka hōʻike LED he hōʻailona ia e hōʻike ana i ka pae kiʻi o ka hōʻike. Hoʻokaʻawale ʻia ka pae hina hina o ka pale wikiō i 64 pae, 128 pae, 256 pae, 512 pae, 1024 pae, 2048 pae, 4096 pae a pēlā aku. ʻO ke kiʻekiʻe o ke kiʻekiʻe hina, ʻoi aku ka maopopo o ka pae kiʻi, ka pae hina hina maʻamau o 256 a ʻoi aku paha, ʻaʻole nui loa ka ʻokoʻa kiʻi.

12, he aha ka hōʻike ʻelua kala, pseudo-color, piha kala?

Ma o nā waihoʻoluʻu like ʻole o nā kukui-emitting diodes hiki ke haku ʻia i nā hōʻike like ʻole, ʻelua kala i haku ʻia me ka ʻulaʻula, ʻōmaʻomaʻo a i ʻole melemele-'ōmaʻomaʻo ʻelua kala, pseudo-color i haku ʻia me ka ʻulaʻula, melemele-'ōmaʻomaʻo, uliuli ʻekolu mau kala like ʻole, piha. -ʻulaʻula, ʻōmaʻomaʻo maʻemaʻe, uliuli maʻemaʻe ʻekolu kala like ʻole.

13, he aha ka moire?

Aia i loko o ka hana pana o ka piha- waihoʻoluʻu LED hōʻike, LED hōʻike pale e loaʻa i kekahi mau irregular wai ripples, keia mau wai ripples i ka physics i kapaia "moiré".

14, he aha ka SMT, he aha ka SMD?

ʻO SMT ka ʻenehana i kau ʻia ma luna (SURFACE MOUNTED ʻenehana no ka pōkole), ʻo ia ka ʻenehana kaulana loa a me ke kaʻina hana i ka ʻoihana hui uila; ʻO SMD ka mea i kau ʻia ma luna o ka ʻili (mea i kau ʻia ma luna no ka pōkole).

ʻO ka hōʻike LED he ʻano hou o ka media hōʻike ʻike, ʻo ia ke kaohi o ke ʻano hōʻike hōʻike kukui-emitting diode o ka pā hōʻike papa pālahalaha, hiki ke hoʻohana ʻia e hōʻike i ka kikokikona, nā kiʻi a me nā ʻano ʻike static a me ka animation, wikiō a me nā ʻano ʻē aʻe. ʻike ikaika, LED uila hōʻike hoʻonohonoho microelectronics ʻenehana, ʻenehana kamepiula, ka hoʻoili ʻana i ka ʻike i hoʻokahi, me nā waihoʻoluʻu ʻālohilohi, ākea ākea ākea, ʻōlinolino kiʻekiʻe, lōʻihi ke ola, kūpaʻa a hilinaʻi, etc. nā wahi haʻuki, hoʻolaha ʻike, hoʻokuʻu nūhou, kālepa palekana, a me nā mea ʻē aʻe, hiki ke hoʻokō i nā pono o nā kaiapuni like ʻole. E like me ka waihoʻoluʻu kumu waihoʻoluʻu hiki ke maheleia i hookahi waihoʻoluʻu hōʻike a piha waihoʻoluʻu hōʻike.
