E hahai i ke ola i hala a me keia manawa o ka projector

Ma mua o ka projector, ua hoʻohana ʻia ka paheʻe ma ke ʻano he huahana koʻikoʻi o ka ʻoihana, a ua ʻike ʻia ʻo ia he ʻano kūikawā o ka projector. kukui, e hoʻohana ana i ka lens a me ke aniani e hōʻike ana i ka malamalama kumu, ke ʻano o nā kiʻi i hōʻike ʻia ma ka paia, ua hoʻoulu ʻia ka manaʻo, akā ma muli o ka mea i ʻike ʻia, ua hoʻopiʻi ʻia ʻo ia i ke kilokilo, huki i ka pepehi kanaka, a hoʻouna ʻia i ka "guillotine".

ʻO ka make ʻana o Chiser, ʻaʻole ia i hoʻopau i ka ʻimi ʻana i ka ʻenehana hou.a ʻo ka German Jewish Kischal i wehewehe mua i ka mea i hana ʻia o ka mīkini paheʻe ma 1645. ʻO ka pūpū mua o ka paheʻe he hao i loko o kahi pahu huinaha, ʻo ke poʻo o ka puʻupuʻu uahi e like me ka cylinder, i mua o ka cylinder, cylinder me kahi. sliding convex lens, hana i kahi lens maʻalahi, aia kahi panel o ka mamao kikoʻī hiki ke hoʻololi ʻia ma waena o ka lens a me ka pahu hao, aia ka pahu i ke kumu kukui, ʻo ke kumu kukui maoli ke kukui. , ka paheʻe i loko o ka slot ma hope o ka convex lens, hoʻā i ke kukui, ke kumu kukui ma o ke aniani hoʻohālikelike convergence, ma o ka alohilohi kiʻi a me ka lens, hana i ka malamalama kolamu i ikeia ma ka paia pale.

I ka makahiki 1845, me ka ulu nui o ka Industrial Revolution, ua komo pū nā mīkini paheʻe i ke au o ka hana ʻenehana, ua hoʻololi ʻia nā kumu kukui mai nā ihoiho mua i nā kukui aila, nā kukui mahu, a hoʻomaka i ka hoʻohana ʻana i nā kumu kukui uila.

Ua hana ʻia nā kiʻi paheʻe mua loa i ke aniani, ma ka pena lima, a ma ka waena o ke kenekulia 19, ma hope o ka hana ʻana o nā ʻAmelika i ke kiʻi celluloid, ua hana ʻia nā paheʻe me ka hoʻohana ʻana i ke kiʻi kiʻi. ma ke kumu o ka mīkini paheʻe o ke kenekulia 19.

Ma hope o ke Kaua Honua II, ʻo ka hana ʻana o nā kamepiula, ka puka nui ʻana o nā kaapuni i hoʻohui ʻia a me ka ʻenehana a me ka hoʻohana nui ʻana o nā ʻenehana hou i lawe mai i ka projector i loko o ke au kamepiula. ,ʻO kā lākou hiʻohiʻona nui ka nui. Ma hope mai, uaʻikeʻia kaʻenehana LCD, aʻo ka uluʻana o kaʻenehana LCD i hoʻomaka ai ka CRT e lilo i moʻolelo.

I ka makahiki 1968, ua hana ʻo GHHeilmeier, he kanaka ʻepekema ʻAmelika ma RCA Corporation, i ke aniani wai i LCD e like me ka hopena hoʻopuehu ikaika, e hana ana i ka prototype o ka ʻoihana LCD, akā ʻaʻole ia i hoʻololi i ka ʻenehana. ua hoʻomohala i nā helu helu a me nā wati me ka ʻenehana LCD e like me ka panel hōʻike, a alakaʻi i nā mea hana he nui e like me Hitachi, NEC a me Toshiba e hui pū me ka hoʻomohala huahana LCD a me nā pae hana.

Hoʻohana ʻia ka ʻenehana LCD i ka mea projection ʻo Epson, e hoʻohana ana i ka aniani wai e hoʻololi i ka hoʻonohonoho ʻana ma lalo o ka hana a nā electrodes i hiki ai i ke kumu kukui ma o ka LCD chip ke hana i nā kiʻi ma o ka lens. ʻOiai ʻo ia ka ʻenehana hou loa o ka manawa, ka LCD projector i loaʻa i ka hana a me ka waihoʻoluʻu defects ma muli o ka monolithic hale, me ka loa haʻahaʻa loa wehe ana helu a me ka resolution.It aole a hiki i 1995 i hookahi-wahi LCD projectors i officially hookomoia i loko o ka makeke, ukali e kekahi 3LCD 'enehana ma 1996. me ka holomua i ka paʻa a me ka hana kala. Ua hui ʻo Sony i ka hoʻomohala ʻana i nā ʻāpana LCD, akā ua hoʻolaha ʻia i ka makahiki 2004 e hoʻōki ʻo ia i ka hāʻawi ʻana i kāna mau ʻāpana LCD no ka hoʻohana kūloko wale nō.

I ka makahiki 1987, ua hoʻomohala ʻo Kauka Larry Hornbeck i ka mīkini DMD mua.Ma ka makahiki 1996, ua hoʻolaha kūkala ʻia ka ʻenehana DLP hoʻoponopono ʻikepili i ka mākeke hōʻike projection, a ua hoʻokuʻu ʻia ka projector DLP mua, ʻehiku mau makahiki ma hope o ka LCD projector.

ʻO ka pahu DLP mua i loaʻa kahi hoʻonā prototype o 16 * 16, ʻoiai ʻo ka DLP projector mua he 300 lumens wale nō, ʻo ia ka mea hiki ke ʻike wale ʻia ma nā wahi ʻeleʻele. kona hoʻomohala ʻenehana, a noho koke i ka mākeke, lawe mai i ka nui o ke kaomi i ka ʻenehana projection LCD.

 

DLP projector i ka mua makeke me keia pono, mai 1997 wale ke kaupaona ana 6 paona InFocus LP420 a hiki i 2005 Samsung pocket projector, DLP projector hoʻomau i ka hoʻomaka hou hōʻoluʻolu i ka manaʻo o "portable", kahili i ka pāʻoihana makeke me eager koi no ka lawe lima, pela loaʻa. he foothold i ka makeke, a ma 2006 i loko o ke ao holoʻokoʻa lanakila ma luna o 20% market mahele, me ka LCD 'enehana. Ma waho aʻeo, ua hoʻohana 'ia ka ekolu-'āpana DLP projector i kiʻekiʻe-hope 'enekinia a me ka hale kiʻiʻoniʻoni papahana, e hana ana no ka oaoieei āpau. i ka hoʻonā kiʻekiʻe a me ke kūpaʻa kiʻekiʻe ʻaʻole hiki i nā mea hoʻolale LCD ke hoʻonā i ka wā i hala.

ʻOiai ʻoi aku ka holomua o ka ʻenehana DLP, ʻoi aku ka maʻalahi o ka ʻenehana LCD ma ke kaulahao hoʻolako, ke kumukūʻai, ke hoʻohālikelike ʻia me DLP, a me nā ʻenehana ʻē aʻe ʻē aʻe, ʻoi aku ka maʻalahi o ke kumukūʻai, ʻoi aku ka paʻa o ka hana, ke ʻano o ka noi, ʻoi aku ma ka post-epidemic. manawa, e lilo ia i mea kūʻai uila kaulana loa i kekahi manawa.


Ka manawa hoʻouna: Dec-27-2021

E ʻoluʻolu e waiho i kāu ʻike waiwai no ka lawelawe hou aʻe mai iā mākou, mahalo!
