I kēia au kikohoʻe, ua hoʻonui nui ʻia ke koi no nā pale hōʻike ikaika a me ka hoʻonā kiʻekiʻe.ʻO kekahi o nā ʻano maʻamau o nā paneli hōʻike i hoʻohana ʻia i nā mea uila like ʻole ʻo ka Thin-Film Transistor (TFT).Hāʻawi kēia mau paneli i nā hiʻohiʻona nani me ka hōʻike ʻana i ka waihoʻoluʻu pololei, e hoʻolilo iā lākou i koho i makemake ʻia no nā smartphones, papa, televise, a me nā noi he nui.Ma kēia ʻatikala, e ʻimi mākou i ka hoʻokaʻawale ʻana a me ke kumu hana o nā panela kala kala TFT e hāʻawi i ka ʻike piha o kā lākou hana.
Hiki ke hoʻokaʻawale ʻia nā ʻāpana pale kala TFT i ʻelua ʻano nui e pili ana i ka ʻenehana i hoʻohana ʻia: In-Plane Switching (IPS) a me Twisted Nematic (TN) panels.Loaʻa i nā ʻano ʻelua nā hiʻohiʻona kūʻokoʻa a lawelawe i nā kumu like ʻole, e hāʻawi ana i ka ʻokoʻa holoʻokoʻa o ka ʻoihana hōʻike.
E hoʻomaka ana me nā panela IPS, ʻike ʻia lākou no kā lākou hana ʻana i nā kala kiʻekiʻe a me nā kihi ʻike ākea.Hoʻohana kēia ʻenehana i kahi hoʻonohonoho aniani wai e hiki ai i ke kukui ke hele i waho me ka ʻole o ka distortion, e loaʻa ai nā kala pololei a ʻikeʻike.Hāʻawi nā panela IPS i ka pololei o ka waihoʻoluʻu me ka nānā ʻole ʻana i ke kihi nānā, e hoʻolilo iā lākou i koho kūpono no nā mea paʻi kiʻi ʻoihana, nā mea hoʻolālā kiʻi, a me nā poʻe e ʻimi nei i nā ʻike ʻike kiʻekiʻe.
Ma ka ʻaoʻao ʻē aʻe, kaulana nā panela TN no kā lākou manawa pane wikiwiki a me nā kumukūʻai kūpono.Ke hoʻohana nei kēia ʻenehana i nā kristal wai i wili ʻia ke hoʻohana ʻole ʻia ka volta, e pale ana i ke kukui.Ke hoʻohana ʻia ka volta, wehe ka ʻili o nā kristal wai, e ʻae i ke kukui e hele a hana i ke kala i makemake ʻia.Hoʻohana maʻamau ʻia nā panela TN i nā hāmeʻa komo komo no ka mea he kumu kūʻai lākou a hāʻawi i ka hana hou kala ʻae ʻia no nā noi o kēlā me kēia lā.
I kēia manawa, e luʻu kākou i ka loina hana o nā ʻāpana pale kala TFT, e kālele ana i ka ʻenehana IPS e like me ka loaʻa ʻana o ka kaulana i nā makahiki i hala.I loko o kahi pānaʻi IPS, aia kekahi mau papa i kuleana no ka hōʻike ʻana i nā kiʻi me ka pololei a me ka ʻoliʻoli.
ʻO ka papa kukui hope, waiho ʻia ma ke kua o ka panel, e hoʻopuka i ke kukui keʻokeʻo e hele ana i kahi polarizer.ʻAe ka polarizer i ka māmā oscillating ma kahi ʻaoʻao e hele ai, e hopena i ka māmā polarized linearly.A laila hiki kēia kukui polarized i ka substrate aniani mua, i ʻike ʻia ʻo ka substrate kānana kala, aia nā kānana kala liʻiliʻi ʻulaʻula, ʻōmaʻomaʻo, a uliuli (RGB).Hoʻopili kēlā me kēia sub-pixel i kekahi o kēia mau kala mua a ʻae wale i kona kala ponoʻī e hele.
Ma hope o ka papa kānana kala, ʻo ia ka papa aniani wai, kahi i hoʻopaʻa ʻia ma waena o ʻelua mau pani aniani.Hoʻopili ʻia nā kristal wai i nā paneli IPS i ko lākou kūlana kūlohelohe.ʻO ka lua aniani substrate, i kapa ʻia ʻo ka TFT backplane, loaʻa nā transistors kiʻiʻoniʻoni ʻoniʻoni e hana ma ke ʻano he hoʻololi no nā pika pākahi.Aia i kēlā me kēia pixel nā sub-pixels hiki ke ho'ā a ho'opau paha ma muli o ke kala i makemake 'ia.
No ka mālama ʻana i ka hoʻolikelike ʻana o nā kristal wai, hoʻohana ʻia kahi māla uila i nā transistors kiʻiʻoniʻoni lahilahi.Ke hoʻohana ʻia ka volta, hana nā transistors kiʻiʻoniʻoni lahilahi ma ke ʻano he mea hoʻololi e hiki ai ke kahe ʻana o ke au, me ka hoʻolikelike ʻana i nā kristal wai a kū pololei.I kēia mokuʻāina, ua wili ʻia ke kukui polarized i hoʻouna ʻia ma o nā kānana kala i 90 degere, e ʻae iā ia e hele i loko o ka substrate aniani ʻelua.Hiki i kēia kukui wili a hiki i ka polarizer luna, i hoʻopaʻa pololei ʻia i ka lalo, e hopena i ka huli ʻana o ke kukui polarized i kona kūlana mua.Hiki i kēia hoʻololi ke hele i ka mālamalama, e hana i ke kala i makemake ʻia.
ʻO kekahi o nā pōmaikaʻi nui o nā panela IPS ʻo ko lākou hiki ke hāʻawi i ka hoʻopiʻi kala like ʻole a me nā kihi ʻike ākea.Ma muli o ka hoʻonohonoho ʻana o nā kristal wai, ʻae nā panela IPS i ka mālamalama e hoʻouna like, e hopena i nā kala like ʻole ma ka hōʻike holoʻokoʻa.Eia kekahi, ʻo nā kihi ʻike ākea e hōʻoia i ka paʻa ʻana o nā hiʻohiʻona i ko lākou mau kala kumu, ʻoiai ke nānā ʻia mai nā hiʻohiʻona like ʻole.
I ka hopena, ua hoʻololi nā panela kala kala TFT, ʻo ia hoʻi nā ʻenehana IPS a me TN, i ka ʻoihana hōʻike me kā lākou mau hiʻohiʻona nani a me nā noi ākea.ʻOi aku ka maikaʻi o nā panela IPS i ka pololei o ka waihoʻoluʻu a me nā kihi ākea ākea, e hoʻolilo iā lākou i kūpono no nā noi ʻoihana.ʻO nā panela TN, ma ka ʻaoʻao ʻē aʻe, hāʻawi i nā manawa pane wikiwiki a me nā kumu kūʻai, e mālama ana i nā pono o nā mea hoʻohana i kēlā me kēia lā.Ma ka hoʻomaopopo ʻana i ka hoʻokaʻawale ʻana a me ka loina hana o nā panela kala kala TFT, hiki iā mākou ke mahalo i nā mea paʻakikī ma hope o nā hāmeʻa i lilo i mea nui o ko mākou ola i kēia au kikohoʻe.
