Sib ntswg nematic (TN) kua siv lead ua kua

Oct 19, 2017

TN (TN Hmong Twisted Nematic acronym) yog kua siv lead ua 90 degrees nistatic nematic kua Crystal. Sib ntswg kua nematic kua (LCD) tshwm nyob rau hauv 70s ntawm lub xyoo pua xeem. Dhau li ntawm cov qauv yooj yim ntawm LCD, nws muaj cov yam ntxwv ntawm cov khoom zoo sib xws, yooj yim tsim technology, raug nqi tsawg thiab lwm yam. Tam sim no, ntau cov tshuab laij leb, cov ntiv taw thiab cov twj siv tau los ua cov khoom siv ua kua li no. Tam sim no, cov LCD manufacturers tseem tsim tau cov khoom zoo li no.

Sib ntsev cov khoom siv ua kua (Crystal) yog tsim los ntawm ob daim iav ntawm ITO iav nrog cov khoom nicatic (TN) ua kua nematic (TN) ua kua, cov thickness ntawm cov kua siv lead ua yog feem ntau yog 5 m, thickness thiab birefringence ntawm cov khoom siv lead ua kua, nyob rau ntawm cov iav AMO txheej coated txheej orientation, Li nrog cov kev sib txuam ntawm cov kua siv lead ua kua molecules thiab txheej txheem nplaum, qhov kev sib txhuam thiab qhov chaw ntawm cov kua siv lead ua kua molecules npaj kom mus raws li kev coj ua nrog 2 - 3 degrees qaij kaum raws li pom hauv daim duab 1- 2. Nyob rau hauv substrate ntawm kev sib txhuam kev sib tsoo rau 90 degrees, yog li ntawd cov kua siv lead ua kua molecules nploog rau hauv 90 degrees, thiab tov nrog ib tug me me ntawm cov roj chiral kua Crystal khoom rau tus neeg sawv cev, lub kua siv lead ua kua molecules distortion nyob rau hauv cov kev coj ntawm cov nyhuv. Lub phom polarizing txuas rau sab nrauv ntawm lub sab nrauv thiab qis iav substrates, thiab txoj kev pom ntawm lub ncov qaum ntuj yog raws li txoj kev sib txhuam ntawm iav substrate, kom pom cov teeb ntawm lub teeb dawb tshwm rau ntawm npo LCD. Thaum lub polarization ntawm qhov teeb meem lub teeb nrog lub kua siv lead ua kua molecules tig 90 degrees, lub teeb taws polarized los ntawm ib tug polarizer, lub xeev ci. Thaum siv cov khoom siv hluav taws xob ua kua (liquid crystal molecules) nrog cov kab hluav taws xob los ntawm cov kab hluav taws xob (polarized light polarization invariant), polarized lub teeb tsis dhau ntawm Polaroid lub teeb sab ntawm lub xeev tsaus nti, Tab sis vim yog cov kua nplaum uas siv cov kua nplaum (TN) tam sim no nyob rau hauv txoj kev mob siab, nws yog qhov loj tshaj plaws ntawm cov kab txuas kom ncav cuag 32, cov ntaub ntawv muaj peev xwm tsawg heev, thiab vim nws tsuas yog ua rau dub thiab dawb , xim, tsis sib xws (20: 1) kua siv ua kua, los ntawm kev xav ntawm tsuas yog 30 degrees, kuj nqaim, vaj huam sib luag loj kawg nkaus ntawm tsuas yog peb nti xwb, thiaj li ua rau daim ntawv thov ntawm nws tus kheej. Nws tsuas siv tau rau ntawm spreadsheets, lub laij lej, thiab kev ua si yooj yim.
