Tus Txheej Txheem Txoj Haujlwm Ntawm Cov Zaub LCD

Dec 18, 2017

Tus qauv ua haujlwm ntawm LCD cov duab: los ntawm cov qauv ntawm LCD, LCD siv los ntawm lub computer lub computer los yog duab system yog ua los ntawm ntau qhov chaw. Lub LCD yog ua los ntawm ob daim iav hlau nrog ib lub thickness ntawm li 1 hli, uas yog sib cais los ntawm ib lub caij nyoog tshwj xeeb ntawm 5 mu m m uas muaj kua siv lead ua kua. Vim tias cov khoom siv lead ua kua tsis yog lub teeb, ces qhov screen rau ob tog nrog lub teeb ua lub teeb ci, thiab lub teeb pom kev hauv cov kua dej ua kua (lossis lub tsho zoo) thiab cov yeeb yaj kiab (reflective plate), cov teeb pom kev tshwm sim yog tsim los ntawm fluorescent tshuaj muaj peev xwm tawm tau lub teeb, nws lub ntsiab tseem ceeb yog muab rau cov teeb tom qab teeb.

Lub teeb tawm ntawm lub teeb ci ntsa iab los ntawm tus txheej thawj ntawm lub txheej hauv qab ntawm cov xim lim dej mus rau hauv cov kua ua kua dej uas muaj hmoov tshav rog. Cov kua dej nyob rau hauv cov kua siv lead ua kua yog muaj nyob rau hauv lub pob zeb me me, thiab ib lub los yog ntau lub hlwb tsim ib qho pixel ntawm qhov screen. Lub tshuab hluav taws xob pob tshab ntawm cov iav phaj thiab cov khoom siv ua kua ua kua yog muab faib ua cov kab thiab cov kab, thiab lub cheeb tsam ntawm cov kua siv ua kua hloov yog hloov ntawm qhov hloov ntawm qhov kev sib tshuam ntawm kab thiab kab. Qhov kev txiav txim ntawm cov khoom siv lead ua kua yog zoo li lub teeb me me. Lub periphery ntawm cov khoom siv lead ua kua yog qhov feem ntawm cov tswj kev sib tsoo thiab tsav tsheb khiav. Thaum cov electrode hauv LCD ua hluav taws xob, cov kua siv lead ua kua molecules yuav pauv, kom cov rays hla los ntawm nws yuav ua kom tsis tu ncua, thiab tom qab ntawd ces lim los ntawm ob theem ntawm lim txheej los qhia rau ntawm qhov screen.
