Cov kua siv lead ua kua dej tau muab cais ua peb hom: zoo li qub, yooj yim, thiab matrix. Ntawm lawv, passive matrix yam tau muab faib ua ntxiv rau cov nematic (TN), super twisted nematic (STN) thiab lwm yam kev hloov siab siv cov khoom siv ua kua qis; yam matrix hom tau roughly dej num raws li nyias zaj duab xis transistor hom (TFT) thiab ob hom dav hlau diode hom (Hlau / Insulator / Hlau; MIM) yog ob txoj kev.
TN, STN, thiab TFT kua siv lead ua muaj qhov sib txawv ntawm qhov saib, lub xim, qhov sib txawv, thiab cov yeeb yaj kiab tso saib zoo vim lawv cov qauv sib txawv ntawm cov kua siv lead ua kua, uas ua kom faib cov khoom hauv lawv daim ntawv thov. Txij li cov ntsiab lus thiab qib ntawm daim ntawv thov kua tshuaj siv coj los ua kua, cov tshuab ua lub tshuab ua haujlwm loj yog siv raws li nyias zaj duab xis transistor (TFT), thiab yog siv rau hauv phau ntawv sau lus, animation, thiab cov duab ua duab. Qhov yooj yim matrix tsav tshuab yog tam sim no raws li kev sib tw-nematic (TN) thiab super-twisted-nruab nrab (STN). Cov kev siv tam sim no feem ntau lo lus processors thiab neeg siv khoom. Ntawm no, TFT LCDs yuav tsum tau muaj peev txheej thiab cov kev yuav tsum muaj, thaum TN thiab STN samfwm kom tsis tshua muaj kev lagluam thiab peev nyiaj.
