Lub hauv paus ntawm PS technology nyob rau hauv kev npaj ntawm nws cov kua siv lead ua kua molecules. Nyob rau hauv cov tsoos TN (Twisted Nematic) panels, kua siv lead ua molecules twist thaum siv hluav taws xob, yog li hloov txoj kev ntawm lub teeb kom ua tiav cov nyhuv. Txawm li cas los xij, txoj kev no muaj kev txwv hauv kev saib lub kaum sab xis thiab xim luam tawm. IPS vaj huam sib luag, ntawm qhov tod tes, hloov cov txheej txheem ntawm cov kua siv lead ua kua molecules, ua rau lawv tig mus rau hauv lub dav hlau, yog li ua tiav lub kaum sab xis pom dav dua thiab muaj tseeb dua xim luam tawm.
Touchscreen technology feem ntau yog ua raws li cov ntsiab lus capacitive lossis resistive. Capacitive touchscreens paub qhov chaw kov los ntawm kev kuaj xyuas cov hluav taws xob tam sim no ntawm tib neeg lub cev, muab qhov zoo xws li cov lus teb ceev thiab ntau- kov muaj peev xwm; thaum cov touchscreens tiv thaiv pom qhov chaw kov los ntawm kev ntsuas siab, muab qhov tseeb dua tab sis lub sij hawm teb qeeb dua. Niaj hnub no IPS touchscreens feem ntau siv cov cuab yeej siv hluav taws xob los muab kev paub zoo dua rau cov neeg siv.
