OLED, LED, LCD, Lanakila a Nalo?

Inā he makahiki 2018 o ka ʻenehana hōʻike nui, ʻaʻole ia he hoʻonui.Hoʻomau ka Ultra HD 4K i ka hoʻonā maʻamau i ka ʻoihana TV.ʻAʻole ʻo High dynamic range (HDR) ka mea nui e hiki mai ana no ka mea ua hoʻokō ʻia.ʻO ia ka ʻoiaʻiʻo no nā pale kelepona, ʻoi aku ka maʻalahi ma muli o ka piʻi ʻana o ka hoʻonā a me ka pixel density i kēlā me kēia iniha.

Akā no nā hiʻohiʻona hou, pono mākou e noʻonoʻo nui i nā ʻokoʻa ma waena o nā ʻano hōʻike ʻelua.ʻIke ʻia nā ʻano hōʻike ʻelua ma nā mākaʻikaʻi, nā kīwī, nā kelepona paʻalima, nā pahupaʻikiʻi, a kokoke i nā mea pale ʻē aʻe.

ʻO kekahi o lākou he LED (Light Emitting Diode).ʻO ia ke ʻano maʻamau o ka hōʻike ma ka mākeke i kēia lā a loaʻa nā ʻano ʻenehana like ʻole.Eia naʻe, ʻaʻole paha ʻoe i kamaʻāina i kēia ʻano hōʻike no ka mea ua like ia me ka lepili LCD (Liquid Crystal Display).Ua like ka LED a me ka LCD ma ke ʻano o ka hoʻohana hōʻike.Inā hōʻailona ʻia kahi pale "LED" ma kahi TV a i ʻole kelepona, he pale LCD maoli nō ia.ʻO ka ʻāpana LED e pili ana i ke kumu kukui wale nō, ʻaʻole ka hōʻike ponoʻī.

Eia kekahi, he OLED (Organic Light Emitting Diode), i hoʻohana nui ʻia i nā kelepona kiʻekiʻe kiʻekiʻe e like me ka iPhone X a me ka iPhone XS hou i hoʻokuʻu ʻia.

I kēia manawa, kahe mālie nā pale OLED i nā kelepona Android kiʻekiʻe, e like me Google Pixel 3, a me nā TV kiʻekiʻe e like me LG C8.

ʻO ka pilikia, he ʻenehana hōʻike ʻokoʻa loa kēia.Wahi a kekahi poʻe ʻo OLED ka ʻelele o ka wā e hiki mai ana, akā ʻoi aku ka maikaʻi ma mua o LCD?A laila, e ʻoluʻolu e hahaiTopfoisone ike.Ma lalo, e hōʻike mākou i nā ʻokoʻa ma waena o nā ʻenehana hōʻike ʻelua, ko lākou pono ponoʻī a me nā loina hana.

ʻokoʻa

I ka pōkole, hoʻohana nā LED, nā pale LCD i nā kukui hope e hoʻomālamalama i kā lākou mau pika, ʻoiai ʻo nā pika OLED e hoʻomālamalama maoli ana.Ua lohe paha ʻoe ua kapa ʻia ʻo OLED pixels "self-lighting" a ʻo ka ʻenehana LCD he "transmissive".

Hiki ke hoʻomalu ʻia ke kukui i hoʻokuʻu ʻia e ka hōʻike OLED.ʻAʻole hiki ke hoʻokō ʻia kēia ʻano maʻalahi, akā loaʻa iā lākou nā hemahemaTopfoisone hoʻolauna ma lalo.

Ma nā kelepona haʻahaʻa haʻahaʻa a me nā kelepona LCD, hoʻohana ʻia nā hōʻike aniani wai LED e hoʻohana i ka "kukui lihi" kahi i loaʻa ai nā LED ma ka ʻaoʻao o ka hōʻike ma mua o ke kua.A laila, hoʻopuka ʻia ke kukui mai kēia mau LED ma o ka matrix, a ʻike mākou i nā pika like ʻole e like me ka ʻulaʻula, ka ʻōmaʻomaʻo, a me ka uliuli.

Olinolino

ʻOi aku ka mālamalama o LED, LCD ma mua o OLED.He pilikia nui kēia ma ka ʻoihana TV, ʻoi aku hoʻi no nā kelepona akamai i hoʻohana pinepine ʻia ma waho, i ka mālamalama o ka lā.

Hoʻohana pinepine ʻia ka mālamalama ma nā huaʻōlelo o "nits" a ʻo ia hoʻi ka ʻōlinolino o ke kukui no ka mika square.ʻO ka ʻōlinolino maʻamau o ka iPhone X me OLED he 625 nits, aʻo ka LG G7 me ka LCD hiki ke loaʻa i kahi kukui kiʻekiʻe o 1000 nits.No nā TV, ʻoi aku ka kiʻekiʻe o ka ʻōlinolino: hiki i nā TV OLED o Samsung ke hoʻokō i ka ʻōlinolino ʻoi aku ma mua o 2000 nits.

He mea koʻikoʻi ka mālamalama i ka wā e nānā ana i ka ʻike wikiō ma ka mālamalama a i ʻole ka lā, a me ka wikiō kiʻekiʻe dynamic range.ʻOi aku ka maikaʻi o kēia hana no ka TV, akā ʻoiai e hoʻokiʻekiʻe nui ana nā mea hana kelepona paʻa i ka hana wikiō, he mea nui hoʻi ka mālamalama i kēia mākeke.ʻOi aku ka kiʻekiʻe o ka mālamalama, ʻoi aku ka nui o ka hopena ʻike, akā ʻo ka hapalua wale nō o ka HDR.

Hoʻohālikelike

Inā ʻoe e kau i ka pale LCD i loko o kahi lumi pouli, ʻike paha ʻoe ʻaʻole ʻeleʻele maoli kekahi mau ʻāpana o ke kiʻi ʻeleʻele paʻa, no ka mea, ʻike ʻia ke kukui hope (a i ʻole ke kukui ʻaoʻao).

ʻO ka hiki ke ʻike i nā kukui i makemake ʻole ʻia hiki ke hoʻopili i ka ʻokoʻa o ka TV, ʻo ia hoʻi ka ʻokoʻa ma waena o kāna mau ʻōlinolino a me nā aka ʻeleʻele.Ma ke ʻano he mea hoʻohana, ʻike pinepine ʻoe i ka ʻokoʻa i wehewehe ʻia i nā kikoʻī o ka huahana, ʻoi aku hoʻi no nā TV a me nā mea nānā.ʻO kēia ʻokoʻa e hōʻike iā ʻoe i ka nani o ke kala keʻokeʻo o ka nānā ke hoʻohālikelike ʻia me kona kala ʻeleʻele.Hiki i ka pale LCD maikaʻi ke loaʻa i kahi ratio like ʻole o 1000: 1, ʻo ia hoʻi, ʻoi aku ka keʻokeʻo i hoʻokahi kaukani manawa ʻoi aku ka ʻeleʻele.

ʻOi aku ka kiʻekiʻe o ka ʻokoʻa o ka hōʻike OLED.Ke lilo ka pale OLED i ʻeleʻele, ʻaʻole e hoʻomālamalama kāna mau pika.ʻO ia ke ʻano e loaʻa iā ʻoe ka ʻokoʻa palena ʻole, ʻoiai ʻoi aku ka maikaʻi o kona helehelena ma muli o ka ʻōlinolino o ke LED ke hoʻomālamalama ʻia.

Kūlana

Loaʻa i nā panela OLED nā kihi ʻike maikaʻi loa, ʻo ka mea nui no ka mea lahilahi loa ka ʻenehana a kokoke loa nā pika i ka ʻili.ʻO ia ke ʻano hiki iā ʻoe ke hele a puni i ka TV OLED a i ʻole ke kū i nā wahi like ʻole o ka lumi noho a ʻike maopopo i ka pale.No nā kelepona paʻalima, he mea koʻikoʻi ke kihi o ka nānā ʻana, no ka mea, ʻaʻole e kūlike loa ke kelepona me ka maka ke hoʻohana ʻia.

He ʻilihune maʻamau ka kihi ʻike ma ka LCD, akā ʻokoʻa kēia ma muli o ka ʻenehana hōʻike i hoʻohana ʻia.Nui nā ʻano like ʻole o nā panela LCD i kēia manawa ma ka mākeke.

ʻO ka mea maʻamau paha ka nematic twisted (TN).Hoʻohana mau ʻia kēia ʻenehana i nā hōʻike kamepiula haʻahaʻa haʻahaʻa, laptops kūʻai ʻole, a me kekahi mau kelepona haʻahaʻa haʻahaʻa.He ʻilihune maʻamau kona kuanaʻike.Inā ʻoe i ʻike i ka nānā ʻana o ka pale kamepiula me ke aka mai kekahi kihi, a laila he panel nematic wili ia.

ʻO ka mea pōmaikaʻi, nui nā mea LCD e hoʻohana nei i ka panel IPS.ʻO IPS (Plane Conversion) ke aliʻi o nā panela aniani i kēia manawa a hāʻawi maʻamau i ka hana kala ʻoi aku ka maikaʻi a me kahi kihi ʻike maikaʻi loa.Hoʻohana ʻia ʻo IPS i ka hapa nui o nā smartphones a me nā papa, kahi helu nui o nā monitor kamepiula a me nā televise.He mea pono e hoʻomaopopo ʻaʻole kūʻokoʻa ka IPS a me LED LCD, kahi hopena ʻē aʻe.

kala kala

Hoʻopuka nā pale LCD hou loa i nā kala kūlohelohe.Eia naʻe, e like me ka manaʻo, pili ia i ka ʻenehana kikoʻī i hoʻohana ʻia.

Hāʻawi nā pale IPS a me VA (Vertical Alignment) i ka pololei o ka waihoʻoluʻu i ka wā e calibrated pono, ʻoiai ʻaʻole maikaʻi nā pale TN.

ʻAʻohe pilikia o ka waihoʻoluʻu o OLED, akā pilikia nā TV OLED mua a me nā kelepona paʻa i ka mālama ʻana i ke kala a me ka hilinaʻi.I kēia lā, ua hoʻomaikaʻi ke kūlana, e like me ka Panasonic FZ952 series o OLED TV a hiki i nā studio grading color Hollywood.

ʻO ka pilikia me nā OLED ko lākou nui o ke kala.ʻO ia hoʻi, hiki i kahi hiʻohiʻona mālamalama ke hopena i ka hiki o ka panel OLED e mālama i ka saturation kala.
