Plaub yam ntxwv ntawm LCD kua Crystal zaub
Jan 10, 2019
Sib piv nrog cov tshuaj CRTs, LCD cov lus qhia tsis yog me me loj, nyias hauv plab, lub teeb hauv qhov hnyav, tsawg zog, kev khiav hauj lwm muaj zog (1.5 mus rau 6V) thiab tsis yog radiative, flicker dawb thiab tuaj yeem ncaj nraim nrog CMOS integrated circuits.
(1) Lub zog txuag, tsis kub
Nws yog ib qho khoom siv uas tsis muaj hwj chim (low-power) uas yuav ua rau tsis-heated (tsuas yog fais fab thiab kub yog tam sim no nyob rau hauv lub teeb nrig lossis LED), thaum CRT tsom xam tsis muaj kev kub ntxhov vim kev siv technology.
(2) nyias lub cev, txuag chaw
Piv nrog rau ntau qhov cumbersome CRT zaub, cov kua siv lead ua yuav tsum tsuas yog ib feem peb ntawm qhov chaw qub.
(3) Tsawg tawg, noj qab haus huv zoo
LCD monitors radiate tsawg dua CRT tus saib (tsawg tsawg, tsis tag tsis muaj hluav taws xob, thiab hluav taws xob cov khoom muaj ntau tshaj lossis tsawg dua), uas yog ib pob rau cov neeg ua haujlwm nyob rau hauv cov computers txhua hnub.
(4) Daim duab yog mos thiab tsis ua rau lub qhov muag
Tsis zoo li CRT tshuab, lub vijtsam LCD tsis nti, uas tuaj yeem txo qhov kev puas tsuaj ntawm lub monitor mus rau ob lub qhov muag, thiab lub qhov muag tsis yoojyim rau qaug zog. Ib cov duab LCD yog ib qho khoom siv uas siv kua siv ua kua ua ib yam khoom. Cov kua nplaum ua kua yog cov organic sib txuas ntawm cov khoom thiab kua. Nws yuav tig mus rau hauv lub taub dej thaum lub ntsuas sov, thiab yuav dhau los ua ib qho crystalline, turbid khoom tom qab txias. Nyob rau hauv qhov kev txiav txim ntawm cov hluav taws xob, cov kua siv lead ua kua molecules yuav hloov nyob rau hauv cov ntawv sib dhos, uas cuam tshuam qhov kev hloov ntawm lub teeb uas dhau los ntawm lawv. Qhov hloov ntawm lub teeb tuaj yeem tau hais tias yog kev hloov ntawm lub teeb thiab tsaus ua los ntawm kev txiav txim ntawm lub ncov qaumteb qabteb. Nyob rau hauv txoj kev no, tib neeg tswj fais fab thaum kawg tswj lub teeb thiab tsaus hloov ntawm lub teeb, thiaj li mus cuag cov hom phiaj ntawm cov duab tso saib.
