Yuav ua li cas tswj cov kua siv lead ua kua molecules nrog lub teeb
Jul 10, 2023| Yuav ua li cas tswj cov kua siv lead ua kua molecules nrog lub teeb
Nyob rau hauv kev tsim ntawm LCD, peb tau ntim ntawm ob daim ntawm polarizing zaj duab xis tuaj yeem hloov lub teeb propagation kev taw qhia thiab cov kua siv lead ua kua txheej los ntawm kev sib tw rau lub ntim membrane. Vim lub teeb tom qab thawj daim ntawm polarizing zaj duab xis tsuas yog ua raws li qhov yuav tsum tau ua nyob rau hauv lub polarization kev taw qhia ntawm lub teeb, yog li cov kua siv lead ua kua molecules tsis nyob rau hauv kev tswj ntawm hluav taws xob teb, orientation ntawm molecules rau thawj lub xeev ntawm "kev sib raug zoo" , yog li molecular orientation ntawm propagation ntawm lub teeb los ntawm cov kua siv lead ua kua kuj tig 90 degree. Vim lub polarization kev taw qhia ntawm ob daim ntawm polarizing zaj duab xis thiab lub kaum sab xis ntawm 90 degrees mus rau thawj qhov chaw, ces muab thim rov qab 90 "lub teeb nyob rau hauv tag nrho los ntawm ob daim ntawm polarizing zaj duab xis tua, ua rau lub LCD npo nthuav tawm lub xeev ntawm tag nrho". dawb ", thaum cov kua siv lead ua kua molecules nyob rau hauv daim ntawv thov hluav taws xob teb lub zog tswj yog txaus los ua nws raws li cov kev taw qhia ntawm lub hluav taws xob teb vertically, lub teeb tsis yog los ntawm cov kua siv lead ua kua molecules, Nws cov kev taw qhia tsis hloov thiab yuav ncaj qha txhaj, rays uas yog tsis muaj dab tsi, tab sis tom qab lub thib ob block ntawm polarizing zaj duab xis yog tag nrho cov nres lub teeb, LCD npo uas yog tag nrho ntawm "dub" lub xeev.Qhov tseeb kuj tuaj yeem yog nyob rau hauv kev tsim cov kua siv lead ua kua molecules thaum thov ib qho hluav taws xob teb ntawm lub xeev. tag nrho "dawb" lub xeev ntawm lub vijtsam, tab sis vim xav txog cov duab ntawm thaj chaw ci feem ntau ntau dua li qhov tsaus ntuj, yog li lub vijtsam tag nrho "dawb" mob tsis yog kua siv lead ua kua molecules yog siv cov hluav taws xob hluav taws xob kom txuag hluav taws xob.
