He aha ka ʻenehana OLED i hoʻohana ʻia i nā televise

Echo Dot Smart Speaker

QLED o Kuantum Dot Light-Emitting Diodes ʻo ia kekahi o nā ʻenehana i loaʻa i nā kīwī o kēia lā a hiki i ka hoʻonā 4K a ʻoi aku paha.

ʻOiai ke kaulana nei ka huaʻōlelo, ke hāpai mau nei ia i nā nīnau. E hoʻomaopopo i ke ʻano o QLED ʻO kāna hana a me nā ʻokoʻa nui e pili ana i nā ʻenehana ʻē aʻe e like me Neo QLED, QNED a me nā hiʻohiʻona e nānā i ke koho ʻana i kahi kīwī hou.

He aha ka ʻenehana QLED?

Hiki ke ʻike ʻia ʻo QLED ma ke ʻano he hoʻomaikaʻi ma LCD. ʻO nā kiko quantum i hoʻohana ʻia i ka ʻenehana he mau kristal nanometer ke anawaena e hoʻopuka ana i nā lōʻihi o ka mālamalama. Hoʻokumu ʻia kēia mau nanocrystals me nā mea semiconducting e hāʻawi i kahi hopena confinement quantum, e kū ana i ka wā e hoʻopaʻa ʻia ai nā electrons i loko o ka mea i nā puke liʻiliʻi loa.

Hiki i ka quantum confinement ke hiki i nā nanocrystals ke hoʻololi a hoʻoponopono i ka lōʻihi o ka nalu o ka mālamalama e like me ko lākou nui, e hana ana i nā kala like ʻole me ka ʻole o ka pono o nā hui kemika.

ʻOiai ua loaʻa i ka ʻenehana quantum dot kāna mau noi pāʻoihana mua i ka makahiki 2013, ma nā polokalamu e like me ka ʻO Sony Triluminos, ua hana ʻia nā haʻawina e pili ana i ka quantum confinement mai ka makahiki 1982, i ka wā i ʻike ai nā ʻepekema Lūkini i kēia hanana.

I loko o nā polokalamu me ka ʻenehana QLED, aia kahi ʻano i hana ʻia me kahi pale LCD, kahi kiʻiʻoniʻoni o nā kiko quantum a me kahi kukui hope i hana ʻia me nā LED e hoʻopuka ana i ke kukui polū.

ʻO ka backlight ka hoʻonohonoho i hana ʻia me kahi kukui a me nā mea ʻē aʻe e hāʻawi i ka mālamalama kūpono no ke kaʻina hana o ka hana ʻana i nā kiʻi ma nā pale i hana ʻole i ko lākou kukui ponoʻī. Hoʻohana maʻamau nā TV LCD i kahi kukui uila keʻokeʻo, ʻoiai ke hoʻohana nei ka ʻenehana QLED i kahi kukui kukui polū.

ʻO nā nanocrystals i loaʻa i nā mea QLED kekahi o nā ʻokoʻa o ka ʻenehana, ʻoiai i loko o ke kiʻiʻoniʻoni aia nā kristal kikoʻī e hana hou i nā aka o ka ʻulaʻula, ʻōmaʻomaʻo a me ka uliuli. Ke pale nei kēia hana i nā ʻano like ʻole o ka tonal, e hana ana i nā kala ʻoi aku ka maʻemaʻe, ʻoi aku ka ʻoiaʻiʻo a me nā hōʻike ʻoi aku ka mālamalama.

Aia paha ʻo QLED i ka maʻamau a i ʻole aia nā TV haʻahaʻa?

ʻOiai ka loaʻa ʻana o ka kaulana, kaʻana like nā QLED TV me kā lākou LCD kahiko a me nā kaikaina LED. Hoʻohana kēia mau ʻenehana i kahi ʻāpana kukui a loaʻa nā hiʻohiʻona like, ʻoiai ʻoi aku ka mālamalama o nā hiʻohiʻona QLED a loaʻa ka gamut kala ākea.

Ma waho aʻe o kēia mau hiʻohiʻona, aia nā televise me ka ʻenehana OLED, e hana ana i nā kiʻi ma o kahi ala ʻē aʻe e hopena i nā kiʻi me nā ʻano like ʻole. No laila, paʻakikī ka wehewehe ʻana i ka maikaʻi o kahi hāmeʻa, e pili ana i ka ʻenehana i hoʻohana ʻia.

Ma kahi hoʻohālikelike maʻamau, hiki iā mākou ke ʻōlelo i ka hōʻike ʻana o nā pale QLED i ʻoi aku ka ʻōlinolino a me nā kala ʻoi aʻe, aʻo nā pale OLED e hāʻawi i nā pae ʻeleʻele hohonu a me nā ʻokoʻa kiʻekiʻe, ma muli o kā lākou ʻenehana diode i hoʻomālamalama ʻia e hiki ai i kēlā me kēia ke hoʻohuli a i ʻole. pakahi.

Ma muli o ka pono o nā hiʻohiʻona QLED a me LED TV i kahi kumu māmā e hana ai i nā kiʻi, ʻaʻole lākou i ka mana māmā pololei ma mua o nā hiʻohiʻona OLED, e hopena i nā ʻeleʻele ʻeleʻele ʻeleʻele.

Ma ka ʻaoʻao ʻē aʻe, hiki i nā TV QLED ke hāʻawi i kahi ākea ākea o nā kala, ʻoi aku ka mālamalama a ʻoi aku ka liʻiliʻi o nā pilikia me ka noʻonoʻo ʻana ma ka pale, kahi mea e hiki ai ke hoʻolilo iā lākou i koho hoihoi no nā kaiapuni māmā.

ʻO ka mea nui loa i ka manawa kūʻai, ʻo ia ka ʻike i ka mea hana, ka laulā kumu kūʻai a me nā kikoʻī ʻenehana o nā hiʻohiʻona i kālai ʻia, e noʻonoʻo ana i kāu kālā e hiki ai ke uku.

Ka ikaika o nā TV QLED

  • nā pale māmā;
  • ʻOi aku ka nui o nā kala;
  • ʻOi aku ke kumu kūʻai ma mua o nā TV OLED;
  • ʻOi aku ka nui o ka mālama ʻana i ka ikehu ma mua o nā hiʻohiʻona LED.

Nā nāwaliwali o nā TV QLED

  • Nā pae ʻeleʻele haʻahaʻa ma mua o nā hiʻohiʻona OLED; ʻeleʻele hiki ke hoʻopololei;
  • ʻO nā kihi nānā haʻahaʻa ma mua o nā hiʻohiʻona OLED;
  • ʻOi aku ka nui o nā manawa pane ma mua o nā hiʻohiʻona OLED.

He ʻokoʻa anei ʻo Crystal UHD mai QLED?

aniani UHD He huaʻōlelo i hoʻohana ʻia e Samsung e wehewehe i kāna mau hiʻohiʻona LCD TV maʻamau e hoʻohana ana i ke kukui LED a hoʻokō i nā hoʻoholo a hiki i 3840 x 2160.

ʻOi aku ka liʻiliʻi o nā hāmeʻa i wehewehe ʻia ʻo Crystal UHD ma mua o nā TV QLED no ka mea ʻoi aku ka nui o nā kikoʻī haʻahaʻa a hiki i nā hopena kiʻekiʻe a hiki i 4K. ʻAʻole like me nā hiʻohiʻona QLED, e hoʻohana ana i nā kiko quantum a hiki ke hoʻokō i nā hoʻoholo ikaika ma waena o 4K a me 8K, ma muli o ke kumu hoʻohālike.

Nā kikoʻī ʻenehana maʻamau o nā kīwī UHD Crystal:

  • ʻO ka helu hōʻano hou a hiki i 60 Hz;
  • ʻO 4K ka hopena kiʻekiʻe loa i loaʻa;
  • ʻAʻohe o lākou komo HDMI 2.1.

He aha ka ʻokoʻa me Neo QLED?

ʻO Neo QLED kahi hoʻonui o ka ʻenehana QLED, i hoʻokō ʻia e Samsung i kāna mau polokalamu i hoʻokuʻu ʻia mai 2021.

ʻO ka ʻokoʻa nui i hōʻike ʻia e Neo QLED, ʻo ia ka hoʻohana ʻana i nā MiniLED, ma muli o ko lākou liʻiliʻi liʻiliʻi, hiki ke hui pū ʻia i nā helu nui ma nā ʻāpana dimming, ʻo ia ka mea i unuhi ʻia i ka mana māmā pololei, nā pae ʻokoʻa maikaʻi a me nā kihi.

Ua like ka QNED?

He aha ka ʻenehana OLED i hoʻohana ʻia i nā televise

Ma kahi o ka hoʻolālā kūʻai aku e loaʻa kahi inoa hanohano (akā ʻaʻole pēlā), hoʻohana ʻo LG's QNED i ka ʻenehana Nanocell, i hana ʻia e ka hui e hōʻike i nā kala ʻoi aku ka pono a me nā kihi ʻike maikaʻi.

Ke kumu anei ʻo QLED i ke ahi?

ʻAe. Aia ma ka QLED TV manuals, aia nā alakaʻi e pale aku i ka waiho ʻana i nā polokalamu me kahi kiʻi paʻa no ka manawa lōʻihi e pale ai i ke ahi. Eia naʻe, pili kēia pilikia i nā TV OLED.

He maikaʻi anei ʻo QLED no ka pāʻani?

ʻAe. ʻOiai ʻoi aku ka mālie o nā manawa pane o nā OLED TV, aia nā koho maikaʻi i ka māhele QLED. Ke koho ʻana i kahi TV no ka pāʻani ʻana, e hōʻoia i ka haʻahaʻa o ka manawa pane a me ka helu hoʻomaha kiʻekiʻe, ʻoi aku ka maikaʻi o ka 120Hz.
