Txoj Cai Ua Haujlwm Ntawm Dub Thiab Dawb LCD Screens
Nov 30, 2023| LCD thev naus laus zis yeej suav nrog cov kua siv lead ua kua ntawm ob kab ntawm cov dav hlau zoo nkauj. Thiab cov grooves saum toj no ob lub dav hlau yog perpendicular rau ib leeg (kev sib tshuam 90 degree). Yog li, yog tias cov molecules ntawm ib lub dav hlau tau teem rau sab qaum teb-sab qab teb, ces cov molecules ntawm lwm lub dav hlau tau teem rau sab hnub tuaj-sab hnub poob, thiab cov molecules nyob nruab nrab ntawm ob lub dav hlau ncaj qha mus rau hauv 90 degree twisted xeev. Vim qhov tseeb tias lub teeb propagates raws li cov kev taw qhia ntawm molecular kev npaj, nws yuav tsum tau twisted 90 degree thaum dhau los ntawm cov kua muaju. Tab sis thaum peb siv lub zog hluav taws xob rau cov kua siv lead ua kua, cov molecules yuav rov ua haujlwm ntsug, tso cai rau lub teeb tawm ncaj qha yam tsis muaj kev sib tw.
