ʻOi aku ka paʻakikī o ke kūʻai ʻana i kahi TV i kēia makahiki. Nā TV me LCD, QLED, Mini-LED, OLED a me nā mea hou loa, loaʻa nā ʻenehana QD-OLED. I ka hoʻomaka ʻana o ka makahiki, ua hoʻolauna ʻo Samsung i ka ʻenehana hōʻike QD-OLED i ʻōlelo ʻia ma mua (i hoʻolauna mua ʻia e ka Samsung S95B TV), i ʻōlelo ʻia ʻoi aku ka maikaʻi ma mua o ka ʻenehana WRGB OLED i hoʻohana ʻia e kāna mea hoʻokūkū LG TV. Akā ʻo ia ka hihia?
Hiki paha iā ʻoe ke hoihoi
ʻO QD-OLED kahi ʻano o ka hōʻike hoʻokuʻu iho, e like me ka hōʻike Super AMOLED i loaʻa i nā smartphones a me nā papa. Galaxy. 'O ia ho'i, hiki i kēlā me kēia pika i loko o kahi pā QD-OLED ke ho'omālamalama iā ia iho a hana i kona kala pono'ī. Eia kekahi, loaʻa nā quantum dot nanocrystals, i ʻike ʻia no nā waiwai ʻoi aku ka maikaʻi, nā waihoʻoluʻu hohonu a me kahi palette kala ākea.
Ke hoʻohana nei kahi hōʻike WRGB OLED i kahi kukui keʻokeʻo e hele ana i nā kānana kala keʻokeʻo, ʻulaʻula, ʻōmaʻomaʻo, a polū e hana i nā kala like ʻole. Aia kekahi subpixel keʻokeʻo. Ua nalowale kekahi o ka malamalama ('ālohilohi) i kona hele ʻana i nā kānana kala, e hopena i ka ʻōlinolino haʻahaʻa. Eia kekahi, ʻaʻole pololei loa ka backlight keʻokeʻo, no laila ʻaʻole maʻemaʻe a piha nā kala i hana ʻia.
Hiki ke hoʻohaʻahaʻa koke ʻia nā mea olaola i hoʻohana ʻia i nā pale OLED ke ʻike ʻia i nā pae kiʻekiʻe o ka mālamalama. No laila pono ʻo LG e makaʻala i ka lōʻihi e hiki ai iā ia ke mālama i nā pae ʻālohilohi kiʻekiʻe, ʻoi aku hoʻi me ka ʻike HDR. No laila, maʻa mau nā TV OLED ma hope o kekahi mau minuke.
ʻO ka ʻenehana QD-OLED, ʻokoʻa, hoʻohana i kahi kukui polū maʻemaʻe e hele ana i nā kiko quantum e hana i nā waihoʻoluʻu ʻulaʻula, ʻōmaʻomaʻo, a me ka uliuli. Hoʻopili nā kiko kuantum i ka ikehu mai nā kumu kukui, e hana ana i ke kukui mono-frequency maʻemaʻe. ʻO ka nui o nā kiko quantum e hoʻoholo i ke kala o nā nanoparticles a lākou e hana ai. No ka laʻana, ʻo ka poʻe me ka nui o 2 nm e hoʻopuka i ke kukui polū, aʻo nā mea me ka nui o 3 a me 7 nm hiki ke hoʻokuʻu i ke kukui ʻōmaʻomaʻo a me ka ʻulaʻula. Ma muli o ka hana ʻana i nā kukui mono-frequency maʻemaʻe, ʻoi aku ka maikaʻi o ka hana hou ʻana o ke kala o kahi panel QD-OLED ma mua o ka pale OLED.
Ma muli o ka liʻiliʻi o ka poho backlight me nā panela QD-OLED, loaʻa iā lākou ka mea nui loa a ʻoi aku ka māmā ma mua o nā pale WRGB OLED. Eia kekahi, hāʻawi lākou i nā waihoʻoluʻu hohonu, ʻoi aku ka ākea o nā kihi nānā a ʻoi aku ka liʻiliʻi i ka pixel burn-in. ʻO QD-OLED ʻo ia ka ʻenehana OLED mua i hoʻokō piha i ka Ultra HD Premium kiʻekiʻe kiʻekiʻe a me nā kikoʻī hoʻohālikelike i hoʻonohonoho ʻia e ka UHD Alliance.
Me ka ʻenehana QD-OLED, ua lawe mai ʻo Samsung i kahi mea hou i ka ʻāpana TV OLED. I kēia manawa pono mākou e kali no nā TV QD-OLED e hāʻule i ke kumukūʻai i ke kiʻekiʻe o kā lākou mau hoa OLED, ʻaʻole pono e hala ma mua o kekahi mau makahiki.
A ua WOLED hou ʻo LG… 🙂
