Pale LCD

ʻO ka Liquid Crystal Display (LCD) kahi mea hōʻike e hoʻohana ana i ka ʻenehana hoʻoili kala e hoʻokō ai i ka hōʻike kala. Loaʻa iā ia nā pono o ka liʻiliʻi, ke kaumaha māmā, ka mālama ʻana i ka mana, ka haʻahaʻa o ka radiation, a me ka maʻalahi o ka lawe ʻana, a hoʻohana nui ʻia i nā TV, nā monitor, nā kamepiula lawe lima, nā papa, nā kelepona akamai a me nā ʻoihana ʻē aʻe.I kēia manawa he nuinā ʻoihana akamai ma ke kahua o ke kīwī.

Ua hoʻomaka ʻia ka LCD i nā makahiki 1960. I ka makahiki 1972, ua hana mua ʻo S.Kobayashi ma Iapana i kahi kīnā - ʻaʻohePale LCD, a laila ua hoʻokumu ʻo Sharp lāua ʻo Epson ma Iapana i ka ʻoihana. I ka hopena o nā makahiki 1980, ua akamai ʻo Iapana i nā ʻenehana hana o STN - LCD a me TFT - LCD, a ua hoʻomaka koke ka ulu ʻana o nā TV wai - kristal. Ma hope mai, ua komo pū ʻo Kōlea Hema a me Taiwan, Kina i kēia ʻoihana. Ma kahi o 2005, ua ukali ka ʻāina nui o Kina. I ka makahiki 2021, ua ʻoi aku ka nui o ka hana ʻana o nā pale LCD Kina ma mua o 60% o ka nui o ka hoʻouna honua, e hoʻolilo ana iā Kina i mea mua ma ka honua.

Hōʻike nā LCD i nā kiʻi ma ka hoʻohana ʻana i nā ʻano o nā kristal wai. Hoʻohana lākou i kahi hopena kristal wai ma waena o ʻelua mau mea polarizing. Ke hele kahi au uila ma o ka wai, hoʻonohonoho hou ʻia nā kristal e hoʻokō i ke kiʻi ʻana. Wahi a ka hoʻohana ʻana a me ka ʻike hōʻike, hiki ke hoʻokaʻawale ʻia nā LCD i ʻāpana - ʻano, kiko - ʻano matrix - ʻano a me kiko - kiʻi matrix - ʻano. Wahi a ke ʻano kino, ua māhele ʻia lākou i TN, STN, DSTN a me TFT. I waena o lākou, ʻo TFT - LCD ka hāmeʻa hōʻike nui.
