Ke ʻimi nei i nā TV pāpaʻi paʻa kiʻekiʻe

I kēia lā, ʻoi aku ka kaulana o nā TV pāhaʻi, a ua lilo nā CRT TV i mea o ka wā ma mua. ʻO ia mau TV he mau hōʻike pālahalaha liʻiliʻi ka mānoanoa, ʻo ia ke kumu i kapa ʻia ai lākou he TV pālahalaha. Ua hoʻomaka lākou e hoʻomohala mahalo i nā ʻenehana - ʻo ia ka LCD a me ka plasma.
ʻAʻole maʻalahi nā TV Flat i ka hoʻolālā ʻana, akā ʻaʻole nō hoʻi i ka pōʻino ke hoʻohana, ʻaʻole lākou e pahū no ka mea ʻaʻole lākou e hoʻohana i ka volta kiʻekiʻe, a ma luna o ia ʻano pale e hiki ai iā ʻoe ke kiʻi i kahi kiʻi paʻa ʻole a paʻa.
ʻOkoʻa nā TV pālahalaha ʻaʻole wale i ka nui o ka pale, he plasma a me LCD.
ʻO nā TV LCD (nā hiʻohiʻona me ka diagonal pale o 7 ʻīniha a 37 ʻīniha), inā ʻoi aku ka diagonal hōʻike ma mua o 37 iniha, a laila hiki ke hoʻopili ʻia nā ʻenehana ʻelua, ʻoiai he kakaikahi ka plasma, akā hoʻohana pū nā TV me ka diagonal pale o 42 iniha. ʻenehana , a kokoke i 50 a 50., ʻoi aku ka nui o ka diagonal, ʻoi aku ka nui o nā TV plasma, ʻoiai aia kekahi mau LCD TV, akā ʻoi aku ka liʻiliʻi.
ʻO ke kiʻekiʻe o ka hoʻonā pale, ʻoi aku ka maikaʻi o ke kiʻi.
He aha nā hōʻike LCD? ʻO kēia ke ʻano o ka hoʻololi ʻana i ka māmā me ka hoʻohana ʻana i nā cell crystal liquid, ʻo ia hoʻi, ua hoʻokumu ʻia ke kiʻi ma luna o ia ʻano ma muli o ka overlapping a i ʻole ka hoʻouna ʻana o ke kukui mai nā kukui backlight e nā cell pixel he nui, lilo lākou i ʻāpana a pani ʻia a ʻike ʻole paha, no laila ʻoe. hiki ke hoʻomalu i ke kukui mai ke kukui, ʻoiai e hana ana i kahi kiʻi paʻa a loaʻa ka laulā o nā kala kala i hōʻike ʻia ma ka pale. Palekana ka ʻenehana LCD no nā maka a ʻaʻohe ona ʻōlinolino.
Akā ʻo ka pale plasma he ʻelua mau papa aniani, aia ma waena o nā ʻāpana pixel, hoʻopuka lākou i ka mālamalama, ʻoiai ua hoʻopiha ʻia lākou me kahi kinoea inert, aia kahi hoʻokuʻu plasma i loko, hāʻawi ia i ka radiation ultraviolet ma muli o ke kukui o ka phosphor, no ka mea, uhi ʻia nā pūnaewele me ia. Ma ke kumu o kahi ʻano like ʻole o ka phosphor, ua hoʻokumu ʻia nā kala kumu 3, e hoʻoholo ana i ka laulā holoʻokoʻa o nā kala kala o ke kiʻi. No ka mea ʻaʻole hoʻouna ke aniani i ka radiation ultraviolet, palekana nā TV plasma no ke olakino kanaka.
He mea koʻikoʻi loa ke koho ʻana i kahi TV papa pālahalaha, no ka mea, ʻo ka maikaʻi o ke kiʻi e pili ana i ka pololei o kēia koho, ʻaʻole like me ka manaʻo o mākou ua like nā ʻenehana ʻelua, akā hiki ke hopena i ka maikaʻi o ka hōʻike. ʻokoʻa.
