ʻIke paha ʻoe i nā ʻokoʻa o LCD, LED a me OLED?

Ua kapa ʻia ka pale hōʻike ʻo ia kekahi o nā mea hou loa o ke kenekulia 20.

ʻAʻole nui loa.He nani ko kakou ola no kona helehelena.

Me ka hoʻomohala ʻana o ka ʻepekema a me ka ʻenehana, ʻaʻole i kaupalena ʻia nā pale hōʻike i ka hoʻohana ʻana i nā pale TV.

Kalepa nui-nuiHōʻike nā LED i nā palee hoʻomaka e uhaʻi i loko o ko mākou ola, e like me nā hale kūʻai kūʻai, nā hale kiʻiʻoniʻoni, hiki ke ʻike ʻia ma nā wahi like ʻole e like me nā wahi haʻuki i loko, a i kēia manawa, ʻo LCD, LED, OLED a me nā huaʻōlelo ʻoihana ʻē aʻe ke hoʻomau nei i ko mākou mau pepeiao, ʻoiai he nui. kamaʻilio ka poʻe e pili ana iā lākou, akā ʻike liʻiliʻi ka poʻe e pili ana iā lākou.

No laila, he aha ka ʻokoʻa ma waena o Lcd, led a me ka oled?

LCD,HOIKE LEDA me OLED

1, LCD

He pōkole ka LCD no Liquid Crystal Display ma ka ʻōlelo Pelekania.

Aia ka nui o TFT, UFB, TFD, STN a me nā ʻano ʻē aʻe.Aia i loko o kona hale ka pōpō palaka, ka pōpō aniani, ke kolu kiʻi, ka substrate aniani, ka polarizer luna, ka papa kuhikuhi, ke aniani wai, ke ʻano ITO conductive, ka conduction point, IPO electrode a me ka polarizer haʻahaʻa.

ʻO ka lawe ʻana i ka pale hoʻolaha LCD ma ke ʻano he laʻana, hoʻohana ia i ka TFT-LCD kaulana loa, ʻo ia ka transistor kiʻiʻoniʻoni ʻoniʻoni ʻoniʻoni.ʻO kāna kumu kumu, ʻo ia ke kau ʻana i ka pahu aniani wai i loko o ʻelua mau substrate aniani like, hoʻonohonoho i ka transistor kiʻiʻoniʻoni lahilahi (ʻo ia hoʻi ʻo TFT) ma ke aniani substrate haʻahaʻa, hoʻonohonoho i ka kānana kala ma ke aniani substrate luna, ka ʻaoʻao o ka huli ʻana o nā molekole kristal wai e hoʻomalu ʻia e ka hōʻailona. a me ka hoʻololi ʻana o ka voltage ma ka transistor kiʻiʻoniʻoni lahilahi, i mea e hoʻokō ai i ke kumu hōʻike ma o ka hoʻomalu ʻana i ke kukui polarized o kēlā me kēia pika.

ʻO ke kumu o ka hōʻike aniani wai ʻo ia ka wai aniani e hōʻike i nā hiʻohiʻona māmā like ʻole ma lalo o ka hana ʻana o nā volta like ʻole.ʻO ka pale hōʻike aniani wai i haku ʻia me ka nui o nā hui aniani wai.Ma ka pale aniani wai aniani monochrome, ʻo ka aniani wai he pixel (ka ʻāpana liʻiliʻi loa i hiki ke hōʻike ʻia ma ka pale kamepiula), ma ka pale aniani wai kala, ʻo kēlā me kēia pika me nā aniani wai ʻulaʻula, ʻōmaʻomaʻo a polū.I ka manawa like, hiki ke noʻonoʻo ʻia aia kahi papa inoa 8-bit ma hope o kēlā me kēia aniani wai, a ʻo ka waiwai o ka papa inoa e hoʻoholo ai i ka ʻōlinolino o kēlā me kēia o nā ʻāpana aniani wai ʻekolu, akā naʻe, ʻaʻole pololei ka waiwai o ka papa inoa. e hoʻokele i ka ʻōlinolino o nā ʻāpana aniani wai ʻekolu, akā hiki ke loaʻa ma o ka "palette.He mea kūpono ʻole ka hoʻolako ʻana i kēlā me kēia pika me kahi papa inoa kino.ʻO kaʻoiaʻiʻo, hoʻokahi wale nō laina o nā papa inoa i lako.Hoʻopili ʻia kēia mau papa inoa i kēlā me kēia laina o nā pika a hoʻouka ʻia i loko o nā mea o kēia laina, e hoʻokele i nā laina pixel āpau e hōʻike i kahi kiʻi piha.

2, NA PALAPALA LED

He pōkole ʻo LED no Light Emitting Diode.He ʻano diode semiconductor, hiki ke hoʻololi i ka ikehu uila i ka ikehu māmā.

Ke hoʻohui ʻia nā electrons me nā lua, hiki ke hoʻomālamalama ʻia ke kukui ʻike, no laila hiki ke hoʻohana ʻia e hana i nā diodes māmā.E like me nā diodes maʻamau, hoʻokumu ʻia nā diodes māmā me kahi hui pn a loaʻa pū kekahi conductivity unidirectional.

ʻO kāna kumu i ka wā e hoʻohui ʻia ai ka voli maikaʻi i ka diode māmā, ua hoʻokomo ʻia nā lua i loko o ka N area mai ka P a me nā electrons injected i loko o ka P mai ka N area, i loko o kekahi mau microns kokoke i ka hui PN, ua hui pū ʻia. me nā electrons ma ka ʻāina N a me nā lua ma ka ʻāina P e hoʻopuka i ka fluorescence hoʻokuʻu ʻole.

ʻOkoʻa nā kūlana ikehu o nā electrons a me nā lua i nā mea semiconductor like ʻole.Ke hui pū ʻia nā electrons a me nā lua, ʻokoʻa ka nui o ka ikehu i hoʻokuʻu ʻia.ʻO ka nui o ka ikehu i hoʻokuʻu ʻia, ʻoi aku ka pōkole o ka nalu o ke kukui i hoʻokuʻu ʻia.Hoʻohana maʻamau nā diodes e hoʻopuka i ke kukui ʻulaʻula, kukui ʻōmaʻomaʻo a i ʻole kukui melemele.

ʻO ka LED i kapa ʻia ʻo Fourth Generation Light Source, nona nā hiʻohiʻona o ka mālama ʻana i ka ikehu, ka mālama ʻana i ke kaiapuni, palekana, ka lōʻihi o ka lawelawe ʻana, ka hoʻohana haʻahaʻa haʻahaʻa, ka wela haʻahaʻa, ka ʻālohilohi kiʻekiʻe, ka wai, ka liʻiliʻi, shockproof, maʻalahi dimming, concentrated kukui kukui, mālama maʻalahi. , etc, hiki ke hoʻohana nui ʻia i nā ʻano ʻano like ʻole e like me ka hōʻike,Hōʻike LED, hoʻonani, kukui hope, kukui maʻamau, etc.

No ka laʻana, ka pale hōʻike LED, Hoʻolaha LED Screen, ke kukui hōʻailona kaʻa, ke kukui kaʻa, ke kukui LCD, nā kukui hale a me nā kumu kukui ʻē aʻe.

3, OLED

He pōkole ʻo OLED no Organic Light-Emitting Diode.ʻIke ʻia hoʻi ʻo ka hōʻike laser uila organik, semiconductor māmā māmā.

Ua ʻike ʻia kēia diode i loko o ke keʻena hana i ka makahiki 1979 e kekahi kumu ʻAmelika ʻAmelika ʻo Deng Qingyun.

Aia ka OLED i waho o ka ʻāpana hōʻike OLED a me nā mea hoʻomālamalama kukui i hoʻopaʻa ʻia i loko, me ka cathode, ka papa hoʻokuʻu, ka papa conductive, anode a me ka base.Hiki i kēlā me kēia ʻāpana hōʻike OLED ke hoʻomalu e hana i nā kukui o ʻekolu kala like ʻole.

Loaʻa i ka ʻenehana hōʻike OLED ke ʻano o ka hoʻomālamalama ponoʻī, me ka hoʻohana ʻana i ka uhi ʻana i nā mea kūlohelohe lahilahi a me ka substrate aniani.Ke holo ka uila, e hoʻokuʻu kēia mau mea ola i ka mālamalama, a nui ke kihi ʻike o ka pale hōʻike OLED, a hiki ke mālama i ka hoʻohana mana.Mai ka makahiki 2003, ua hoʻohana ʻia kēia ʻenehana hōʻike i nā mea pāʻani mele MP3.

I kēia mau lā, ʻo kahi mākaʻikaʻi koʻikoʻi o ka noi OLED ka pale kelepona paʻalima.Hiki i ka pale OLED ke hōʻike i ke ʻano like ʻole o ke kiʻi, a ʻoi aku ka ʻike o ke kiʻi hōʻike.Ma muli o nā hiʻohiʻona o ke aniani wai, ʻaʻole kākoʻo ka pale LCD i ka piko.ʻO ka ʻokoʻa, hiki ke hana ʻia ʻo OLED i pale curved.

Nā ʻokoʻa ma waena o nā ʻekolu

1, Ma ka gamut kala

Hiki i ka pale OLED ke hōʻike i nā kala pau ʻole a ʻaʻole i hoʻopilikia ʻia e nā backlights, akā ʻo ka LED Screen me ka ʻoi aku ka maikaʻi a me ka ʻike maka.

Loaʻa i nā Pixels nā pōmaikaʻi nui i ka hōʻike ʻana i nā kiʻi ʻeleʻele āpau, i kēia manawa, aia ka gamut kala o ka pale LCD ma waena o 72 a me 92 pakeneka, ʻoiai ʻo ka pale alakaʻi ma luna o 118 pakeneka.

2, Ma ke kumu kūʻai

ʻOi aku ka nui o nā pale LED o ka nui like ma mua o ʻelua manawa e like me nā pale LCD ma ka pā wikiō liʻiliʻi pixel pitch alakaʻi ʻia, ʻoiai ʻoi aku ka pipiʻi o nā pale OLED.

3, Ma ke ʻano o ka ʻenehana oʻo o ka mālamalama a me ka ʻole.

ʻOi aku ka maikaʻi o ka pale LED ma mua o ka pale LCD a me ka OLED i ka mālamalama a me ka ʻole, ʻoi aku ka nui ma ka pā wikiō alakaʻi nui no ka pale hoʻolaha a i ʻole ka hoʻohana ʻana i nā hōʻailona kikohoʻe kūloko.

ʻOiai ʻo LCD a i ʻole OLED no ka pā wikiō kikohoʻe nui e pono e hoʻopili ʻia, ʻo ke āpau ma waena o nā panela e hopena i ka hana a me ka manaʻo o ka mea nānā.

4, Ma ke ʻano o ka hana wikiō a me ke kihi o ka hōʻike

ʻO ka hōʻike kikoʻī ʻo ia ka liʻiliʻi o ka ʻike maka o ka pale LCD, ʻoiai ʻo ka pale LED e ʻoluʻolu i ka waiho ʻana a me ka hana ikaika me ka hoʻomohala ʻenehana o ka hōʻike alakaʻi, ʻo ia hoʻi, ua lawa ka hohonu o ka pale LED ʻoi loa i loko.ʻO YONWAYTECH i alakaʻi i ka hopena hōʻike.
