1. He aha ke LED?
ʻO LED (Light-Emitting Diode) kahi mea uila nui loa. Hana ʻia ia me nā mea semiconductor kūikawā e like me ka gallium nitride a hoʻokuʻu i ka mālamalama i ka wā e hoʻopili ʻia ai ka uila i ka chip. E hoʻopuka nā mea like ʻole i nā kala like ʻole o ka mālamalama.
Nā pono o LED:
Hiki i ka ikehu: Ke hoʻohālikelike ʻia me nā kukui uila a me nā kukui uila, hiki i ka LED ke hoʻololi maikaʻi i ka ikehu uila i māmā, e mālama ai i ka uila.
Ola lōʻihi: Hiki i ke ola lawelawe o LED ke hiki i 50,000 mau hola a i ʻole ka lōʻihi, me ka ʻole o nā pilikia o ka filament burnout a i ʻole ka lole electrode.
Pane wikiwiki:He pōkole loa ka manawa pane o LED, hiki ke hana i nā milliseconds, he mea koʻikoʻi ia no ka hōʻike ʻana i nā kiʻi ikaika a me nā hōʻailona hōʻailona.
ʻO ka liʻiliʻi liʻiliʻi a me ka maʻalahi: He paʻa loa ka LED a hiki ke hoʻohui maʻalahi i nā mea like ʻole a hana ʻia i nā ʻano like ʻole.
No laila, hoʻohana nui ʻia ʻo LED i nā ʻano like ʻole e like me ke kukui home, ka hoʻolaha pāʻoihana, nā hōʻikeʻike kahua, nā hōʻailona kaʻa, nā kukui automotive, nā huahana uila, etc. .
2. Nā ʻano o nā hōʻike LED
2.1 Nā ʻano kala hōʻike LED
Nā hōʻike LED kala hoʻokahi:Hōʻike kēia ʻano hōʻike i hoʻokahi kala wale nō, e like me ka ʻulaʻula, ka ʻōmaʻomaʻo, a i ʻole ka uliuli. ʻOiai he haʻahaʻa haʻahaʻa kona kumukūʻai a me kahi hoʻolālā maʻalahi, ma muli o kāna hopena hōʻike hoʻokahi, ʻaʻole hoʻohana ʻia i kēia manawa a no ka ʻike. Hiki ke ʻike ʻia i kekahi manawa i kekahi mau manawa hōʻike ʻike maʻalahi, e like me nā kukui uila a i ʻole nā papa hōʻike kūlana hana ma nā hale hana hale hana.
Hōʻike LED ʻelua kala:Ua haku ʻia me nā LED ʻulaʻula a me ka ʻōmaʻomaʻo. Ma ka hoʻomalu ʻana i ka ʻōlinolino a me ka hui kala, hiki iā ia ke hōʻike i nā ʻano kala like ʻole, no ka laʻana, melemele (kahi hui o ka ʻulaʻula a me ka ʻōmaʻomaʻo). Hoʻohana pinepine ʻia kēia ʻano hōʻike i nā hiʻohiʻona hōʻike ʻike me nā koi kala ʻoi aʻe, e like me nā pale hōʻike hōʻike hoʻokuʻu kaʻa kaʻa, hiki ke hoʻokaʻawale i nā laina kaʻa, hoʻopau i ka ʻike, a me ka ʻike hoʻolaha ma o nā kala like ʻole.
Hōʻike LED kala piha:Hiki iā ia ke hōʻike i nā waihoʻoluʻu like ʻole i hana ʻia e ka hui ʻana o nā kala kumu ʻulaʻula, ʻōmaʻomaʻo, a me ka uliuli a loaʻa nā kala momona a me ka hōʻike ikaika. Hoʻohana nui ʻia ia ma nā wahi me nā koi kiʻekiʻe no nā hiʻohiʻona hiʻohiʻona, e like me nā hoʻolaha hoʻolaha nui o waho, nā kahua hoʻokō o ke kahua, nā pale hoʻolaha ola o nā hanana haʻuki, a me nā hōʻike pāʻoihana kiʻekiʻe.
2.2 Nā ʻano Pitch Pitch LED Hōʻike
Nā kiʻi pika maʻamau:Loaʻa iā P2.5, P3, P4, a me nā mea ʻē aʻe. ʻO ka helu ma hope o P e hōʻike ana i ka pitch ma waena o nā kiko pika pili (ma nā millimeters). No ka laʻana, ʻo ka pitch pixel o kahi hōʻike P2.5 he 2.5 millimeters. He kūpono kēia ʻano hōʻike no ka nānā ʻana i loko a me ka nānā kokoke, e like me nā lumi hālāwai hui (e hoʻohana ana i nā hōʻike P2.5 - P3 e hōʻike i nā mea hālāwai) a me nā wahi hoʻolaha i loko o nā hale kūʻai (P3 - P4 no ka pāʻani ʻana i nā hoʻolaha waiwai).
Kūleʻa maikaʻi:ʻO ka mea maʻamau, pili ia i kahi hōʻike me kahi pitch pixel ma waena o P1.5 - P2. No ka liʻiliʻi o ka pitch pixel, ʻoi aku ka kiʻekiʻe o ke kiʻi. Hoʻohana nui ʻia ia ma nā wahi me nā koi kiʻekiʻe loa no ka akaka kiʻi, e like me ka nānā ʻana a me nā kikowaena kauoha (kahi e pono ai nā limahana e nānā pono i ka nui o nā kikoʻī kiʻi nānā) a me nā kiʻi kiʻi TV (no ke kūkulu ʻana i nā pale kāʻei nui e hoʻokō i nā hiʻohiʻona virtual maoli. a me ka hōʻike ʻana i nā hopena kūikawā).
Micro pitch:ʻO ka pixel pitch he P1 a i ʻole ka liʻiliʻi, e hōʻike ana i kahi ʻenehana hōʻike ultra-high-definition. Hiki iā ia ke hōʻike i nā kiʻi maikaʻi loa a ʻoiaʻiʻo hoʻi a hoʻohana ʻia i nā hōʻike pāʻoihana kiʻekiʻe (e like me nā puka makani hale kūʻai nani no ka hōʻike kikoʻī o nā huahana) a me ka ʻike ʻike noiʻi ʻepekema (e hōʻike ana i ka ʻikepili noiʻi ʻepekema paʻakikī i nā kiʻi hoʻonā kiʻekiʻe).
2.3 Nā ʻano hoʻohana hōʻike LED
Hōʻike LED i loko:He haʻahaʻa ka ʻōlinolino no ka nāwaliwali o ke kukui ambient o loko. He liʻiliʻi ka pitch pixel e hōʻoia i ka hopena kiʻi akaka ke nānā ʻia ma kahi mamao kokoke. Hoʻohana nui ʻia ia i loko o nā lumi hālāwai, nā hale hōʻikeʻike, i loko o nā hale kūʻai kūʻai, nā kahua kahua (no nā hana o loko), a me nā wahi ʻē aʻe.
Pākuʻi LED waho:Pono ia i ka ʻōlinolino kiʻekiʻe e pale aku i ka ikaika o ka lā a me nā kukui ambient paʻakikī. Hiki ke ʻokoʻa ka pitch pixel e like me ka mamao o ka nānā ʻana a me nā koi. ʻIke pinepine ʻia ia ma nā wahi hoʻolaha waho, nā kahua o waho o nā kahua haʻuki, a me nā keʻena kaʻa (e like me nā pale hōʻikeʻike waho ma nā kahua mokulele a me nā kahua kaʻaahi).
2.4 Hōʻike i nā ʻano maʻiʻo
Hōʻike kikokikona
Hoʻohana nui ʻia ia e hōʻike maopopo i ka ʻike kikokikona, me ka ʻike kikoʻī kiʻekiʻe a me ka ʻokoʻa maikaʻi. ʻO ka mea maʻamau, hiki i kahi hōʻike kala hoʻokahi a i ʻole ke kala ʻelua ke hoʻokō i nā koi, a ʻoi aku ka haʻahaʻa o ka hoʻomaha. He kūpono ia no ke alakaʻi ʻana i ka lehulehu, ka hoʻouna ʻana i ka ʻike kūloko i nā ʻoihana, a me nā hiʻohiʻona ʻē aʻe.
Hōʻike kiʻi
Hoʻopili ia i ka hōʻike ʻana i nā kiʻi me ka hoʻonā kiʻekiʻe a me ke kala pololei. Hiki iā ia ke hōʻike maikaʻi i nā kiʻi kūʻokoʻa a me ka ikaika. Pono ia e kaulike i ka ʻōlinolino a me ka ʻokoʻa a me ka hana kala ikaika. Hoʻohana pinepine ʻia i nā hōʻike pāʻoihana a me nā hōʻikeʻike kiʻi.
Hōʻike wikiō
ʻO ke kī ʻo ka hiki ke pāʻani i nā wikiō me ka maʻalahi, me ka helu hoʻomaha kiʻekiʻe, ka hana hou kala kiʻekiʻe, a me ka hiki ke hoʻopaʻa i ka laulā dynamic a me ka ʻokoʻa. Hoʻopili maikaʻi ʻia ka pitch pixel me ka mamao nānā. Hoʻohana ʻia ia i loko o ka media hoʻolaha, nā hana keaka, a me nā hanana hanana.
Hōʻike kikohoʻe
Hōʻike ʻo ia i nā helu ma ke ʻano maopopo a kaulana, me nā ʻano helu maʻalahi, ka nui o nā font nui, a me ka mālamalama kiʻekiʻe. Ua kaupalena ʻia nā koi no ke kala a me ka helu hoʻomaha, a ʻo ka mea maʻamau, lawa ka hōʻike hoʻokahi kala a ʻelua paha. Hoʻohana ʻia ia no ka manawa a me ka helu ʻana i nā hanana haʻuki, hoʻokuʻu ʻike i nā ʻoihana kālā, a me nā hiʻohiʻona ʻē aʻe.
3. Nā ʻano ʻenehana LED
LED kukui pololei:Ma kēia ʻenehana, ua māhele like ʻia nā peʻa LED ma hope o ka pā aniani wai, a ua māhele like ʻia ke kukui i ka pale holoʻokoʻa ma o kahi pā alakaʻi kukui. Hiki i kēia ala ke hāʻawi i ka like ʻana o ka ʻōlinolino ʻoi aku ka maikaʻi, hōʻike i nā waihoʻoluʻu ʻoi aku ka maikaʻi a me ka ʻokoʻa kiʻekiʻe aʻe, a hoʻohana nui ʻia i waena o nā kiʻekiʻe kiʻekiʻe-kiʻekiʻe kiʻekiʻe wai aniani kiaʻi a me nā televise. Eia nō naʻe, ma muli o ka pono o nā pahu hou, ʻoi aku ka mānoanoa o ka module, hiki ke hoʻopilikia i ka lahilahi o ka pale, a ʻoi aku ka kiʻekiʻe o ka mana.
LED kukui lihi:Hoʻokomo kēia ʻenehana i nā peʻa LED ma ka lihi o ka pale a hoʻohana i kahi ʻano alakaʻi alakaʻi kukui kūikawā e hoʻouna i ka mālamalama i ka ʻaoʻao hōʻike holoʻokoʻa. ʻO kona pōmaikaʻi, hiki iā ia ke hoʻokō i kahi hoʻolālā ʻoi aku ka lahilahi, e hoʻokō i ka noi mākeke no kahi hiʻohiʻona lahilahi a māmā, a he haʻahaʻa haʻahaʻa. Eia nō naʻe, no ka mea aia ke kumu kukui ma ka lihi o ka pale, hiki ke alakaʻi i ka mahele like ʻole o ka ʻōlinolino o ka pale. Ma ke ʻano o ka hoʻohālikelike a me ka hana kala, ʻoi aku ka haʻahaʻa o ka LED kukui pololei. I kekahi mau hihia, hiki mai ka leaka māmā i nā kiʻi ʻeleʻele.
Nā LED hui piha:ʻO ke kukui piha piha he mana i hoʻonui ʻia o ke kukui kukui pololei. Ma ka hoʻokaʻawale ʻana i nā pahu i nā ʻāpana a me ka hoʻomalu kūʻokoʻa i ka ʻōlinolino, loaʻa iā ia ka dimming kūloko. Hāʻawi kēia ʻenehana i ka ʻokoʻa kiʻekiʻe a me ka hana kala. ʻOi loa i ka wā e hōʻike ana i ka ʻike HDR, hiki iā ia ke hoʻihoʻi maikaʻi i nā kikoʻī o nā hiʻohiʻona a me nā aka a hoʻonui i ka ʻike ʻike. Ma muli o kāna hoʻolālā kaapuni paʻakikī a me ka pono o nā beads no ka hoʻokō ʻana i ka dimming kūloko, ʻoi aku ka kiʻekiʻe o ke kumukūʻai, a ʻoi aku ka kiʻekiʻe o nā koi no ka hoʻokele ʻana i nā chips a me nā ʻōnaehana mana.
OLED:ʻO OLED kahi ʻenehana hōʻike hoʻomālamalama ponoʻī, a hiki i kēlā me kēia pika ke hoʻopuka i ke kukui kūʻokoʻa me ke kukui ʻole. ʻO kāna mau mea maikaʻi, ʻo ia ka ʻokoʻa kiʻekiʻe, ka ʻeleʻele hohonu, nā kala ʻulaʻula, ka gamut kala ākea, a me ka manawa pane wikiwiki, kūpono no ka hōʻike ʻana i nā kiʻi hoʻoikaika. Hiki ke hana ʻia nā pale OLED a lahilahi loa a hiki ke maʻalahi, kūpono i nā mea hiki ke hoʻopili. Eia nō naʻe, ʻoi aku ka kiʻekiʻe o ke kumukūʻai o ka ʻenehana OLED, a ʻaʻole maikaʻi ka maikaʻi o kāna hana ʻālohilohi i nā wahi māmā ikaika e like me nā ʻenehana ʻē aʻe.
QLED:Hoʻokumu ʻia ʻo QLED ma luna o ka ʻenehana backlight LED a hoʻohui i nā mea quantum dot, hiki ke hāʻawi i kahi gamut kala ākea a ʻoi aku ka pololei o ka hana kala. Loaʻa ka QLED i nā pono o ke kukui LED, e like me ke kukui kiʻekiʻe, ke ola lōʻihi, a me ka hoʻohana haʻahaʻa haʻahaʻa. I ka manawa like, ʻoi aku ka maikaʻi o ke kumukūʻai hana ma mua o OLED, me kahi kiʻekiʻe o ke kumu kūʻai. Eia nō naʻe, ke hilinaʻi nei ʻo QLED i kahi backlight, a ʻoi aku ka maikaʻi o kāna hana ʻokoʻa a me ka ʻeleʻele ma mua o OLED.
LED liʻiliʻi:ʻO Mini LED kahi ʻenehana hou. Ma ka hōʻemi ʻana i nā peʻa LED i ka pae micron a me ka hoʻohana ʻana i kahi hoʻolālā backlight kukui pololei, hoʻomaikaʻi nui ia i ka ʻokoʻa a me ka like ʻana o ka mālamalama a hāʻawi i kahi hopena kiʻi maikaʻi aʻe. ʻAʻole hoʻoili wale ʻo Mini LED i nā pono o ka LED kuʻuna akā hiki ke hāʻawi i ka hoʻonā kiʻekiʻe a me nā kikoʻī kiʻi. Ke hoʻohālikelike ʻia me OLED, ʻoi aku ka lōʻihi o ke ola ʻana a ʻoi aku ka liʻiliʻi o ke ahi, a ʻoi aku ka haʻahaʻa o ke kumukūʻai.
LED micro:Hoʻemi hou ʻo Micro LED i nā ʻāpana LED i ka micron a i ʻole nanometer pae a hoʻoneʻe pololei iā lākou i ka panel hōʻike e hoʻokuʻu i ka mālamalama e like me nā pika kūʻokoʻa, loaʻa nā mea maikaʻi o ka ʻenehana hoʻomālamalama ponoʻī, hāʻawi i ka ʻokoʻa kiʻekiʻe, nā kala pololei, nā kukui maikaʻi loa, a me ka wikiwiki. manawa pane. Hiki ke hana ʻia i ka ʻenehana Micro LED, he haʻahaʻa haʻahaʻa, a he lōʻihi ke ola. ʻOiai he kiʻekiʻe kona kumukūʻai hana a he nui ka paʻakikī ʻenehana, loaʻa iā ia ka mākeke ākea ākea.
