ʻO ke kūlana hoʻomohala o TFT LCD

ʻO nā pale kala TFT (Thin-Film Transistor), ma ke ʻano he mea koʻikoʻi o ka ʻenehana hōʻikeʻike hou, ua loaʻa ka wikiwiki o ka ʻenehana a me ka hoʻonui ʻana i ka mākeke mai ko lākou kūʻai ʻana i nā makahiki 1990. Noho mau lākou i ka hopena hōʻike nui i nā mea uila uila, nā mea hana ʻenehana, a me nā ʻano ʻē aʻe. Hoʻonohonoho ʻia kēia ʻano loiloi i ʻekolu mau ʻano: ka mōʻaukala hoʻomohala, ke kūlana ʻenehana o kēia manawa, a me nā mea e hiki mai ana.

I. Moʻolelo Hoʻomohala o TFT-LCD
Ua puka mai ka manaʻo o ka ʻenehana TFT i ka makahiki 1960, akā ʻaʻole i ka makahiki 1990 i hoʻokō ai nā hui Kepani i ka hana pāʻoihana nui, no nā kamepiula kamepiula a me nā mea nānā LCD mua. Ua kāohi ʻia nā TFT-LCD o ka hanauna mua e ka haʻahaʻa haʻahaʻa, ke kumu kūʻai kiʻekiʻe, a me nā hua hana haʻahaʻa, akā ua hoʻololi mālie lākou i nā hōʻike CRT ma muli o nā pono e like me ka slim form factor a me ka hoʻohana haʻahaʻa haʻahaʻa. Mai ka makahiki 2010 mai, ua komo nā TFT-LCD i nā mākeke e like me nā smartphones, nā hōʻike kaʻa, nā mea lapaʻau, a me nā ʻōnaehana hoʻokele ʻenehana, ʻoiai ke alo nei i ka hoʻokūkū hoʻokūkū mai OLED. Ma o ka hoʻonui ʻana i ka ʻenehana e like me ka Mini-LED backlighting, ua hoʻonui ʻia ka hana i kekahi mau noi, me nā mea nānā kiʻekiʻe.

II. Kūlana ʻenehana i kēia manawa o TFT-LCD
ʻO ke kaulahao ʻoihana TFT-LCD ʻoi loa, me nā kumukūʻai hana ʻoi aku ka haʻahaʻa ma mua o nā OLED, ʻoi aku ka nui o nā noi nui e like me nā TV a me nā mākaʻikaʻi, kahi e hoʻomalu ai i ka mākeke. ʻO ke kaomi hoʻokūkū a me ka hana hou e alakaʻi nui ʻia e ka hopena o OLED. ʻOiai ʻoi aku ka maikaʻi o ka OLED i ka maʻalahi a me ka ratio like ʻole (ma muli o kona ʻano pilikino me ka ʻokoʻa pau ʻole), ua hōʻemi ʻo TFT-LCD i ke āpau ma o ka hoʻohana ʻana i ka backlighting Mini-LED me ka dimming kūloko e hoʻomaikaʻi i ka hana HDR. Ua hoʻonui ʻia ka hoʻohui ʻenehana ma o nā quantum dots (QD-LCD) no ka gamut kala ākea a me ka hoʻohui ʻana o ka ʻenehana paʻi, me ka hoʻonui ʻana i ka waiwai.

III. Nā Manaʻo e hiki mai ana o TFT-LCD
ʻO ke kukui uila liʻiliʻi, me kāna mau tausani micro-LED no ka dimming kūloko, e hoʻokō i nā pae like ʻole kokoke i nā OLED ʻoiai e mālama ana i ka lōʻihi a me nā uku kumukūʻai o LCD. Hoʻonoho kēia iā ia ma ke ʻano he kuhikuhi nui i ka mākeke hōʻike kiʻekiʻe. ʻOiai ʻoi aku ka liʻiliʻi o ka TFT-LCD maʻalahi ma mua o ka OLED, ua ʻike ʻia ka hiki ke kulou liʻiliʻi me ka hoʻohana ʻana i nā aniani ultra-thin a i ʻole nā ​​substrate plastic, hiki ke ʻimi i nā noi e like me nā mīkini a me nā mea hiki ke hoʻohana. Ke hoʻomau nei ka hoʻonui ʻana o nā hiʻohiʻona noiʻi ma kekahi mau ʻāpana—no ka laʻana, ʻo ke ʻano o nā pale he nui i nā kaʻa ikehu hou e hoʻoikaika i ke kūlana koʻikoʻi o TFT-LCD, no ka hilinaʻi a me ka maikaʻi o ke kumukūʻai. ʻO ka ulu ʻana o nā mākeke o nā ʻāina ʻē, e like me India a me Asia Hema, kahi e piʻi ai ka noi no nā mea uila uila, e hoʻomau i ka hilinaʻi ma TFT-LCD ma waena o nā mea haʻahaʻa haʻahaʻa.

Ua lanakila ʻo OLED i nā mākeke hōʻike kiʻekiʻe a me nā mākeke hōʻike maʻalahi a noho pū me Micro LED, e kuhikuhi ana i nā pale ʻoi aku ka nui (e laʻa, nā pā wikiō pāʻoihana). I kēia manawa, ke hoʻomau nei ka TFT-LCD i ke komo ʻana i waena o nā mākeke nui ma muli o kāna kumu kūʻai. Ma hope o nā makahiki he ʻumi o ka hoʻomohala ʻana, ua hiki i ka TFT-LCD ke oʻo, akā mālama ia i ka hiki i ka wā lōʻihi ma o nā ʻenehana ʻenehana e like me Mini-LED a me IGZO, a me ke kāʻei ʻana i nā mākeke niche e like me ka automotive a me nā noi ʻoihana. Ke mau nei kona waiwai nui: ʻoi aku ka haʻahaʻa o ke kumukūʻai hana no nā panela nui ma mua o ka OLED.

Ke nānā nei i mua, e kālele nui ana ʻo TFT-LCD i ka hoʻokūkū ʻokoʻa ma mua o ke kū pololei ʻana iā OLED. Me ke kākoʻo o nā ʻenehana e like me Mini-LED backlighting, manaʻo ʻia e hana i nā manawa hou i ka mākeke kiʻekiʻe. ʻOiai ʻo ka hoʻololi ʻana o ka ʻenehana hōʻike he ʻano hiki ʻole ke hoʻohuli ʻia, ʻo TFT-LCD, i kākoʻo ʻia e kahi kaiaola oʻo a me ka hoʻomau mau ʻana, e mau nō ia i ʻenehana kumu i ka ʻoihana hōʻike.
