Lub hauv paus ntsiab lus ua haujlwm ntawm LCD kua siv lead ua zaub module
Oct 18, 2022| Liquid crystal screen (LCD) yog ib qho khoom siv hluav taws xob ntau hauv peb lub neej. Thaum hnov nws lub npe, tej zaum koj yuav xav tias muaj kua hauv nws?
Muaj tseeb muaj cov kua dej tshwj xeeb hauv LCD npo, uas yog hu ua kua siv lead ua kua. Raws li nws lub npe qhia, cov kua siv lead ua kua muaj cov kua thiab cov khoom siv lead ua: ntawm ib sab, nws tuaj yeem ntws zoo li cov kua; Ntawm qhov tod tes, nws cov molecules tau teem rau hauv ib qho kev txiav txim zoo li cov khoom siv lead ua, uas tuaj yeem hais tau ntawm cov kua thiab cov khoom. xeev nruab nrab. Los ntawm kev siv cov hluav taws xob sib txawv rau cov kua siv lead ua kua txheej hauv lub vijtsam, qhov kev npaj ntawm nws cov molecules tuaj yeem hloov pauv, thiab cov khoom sib txawv ntawm qhov muag pom, xws li lub teeb xa tawm, tuaj yeem tshwm sim. Cov nyhuv photoelectric no yog lub hauv paus ntsiab lus ntawm cov kua siv lead ua kua screen duab.
Muaj ntau hom kua siv lead ua kua, cov khoom siv yog biphenyl kua siv lead ua, phenylcyclohexane kua siv lead ua thiab ester kua siv lead ua. Cov ntxaij vab tshaus cov ntxaij vab tshaus xws li CRT daim duab tube qhia (cov kab hluav taws xob zoo siab phosphors nyob rau sab hauv ntawm lub vijtsam los tso saib cov duab) feem ntau loj loj, thaum cov kua siv lead ua kua cov ntxaij vab tshaus tuaj yeem nyias thiab lub teeb, thiab yuav tsum tau siv hluav taws xob tsawg thiab siv zog, yog li ntawd lawv thiaj li yooj yim dua. nyiam.
