Mfundo yaikulu ndi kutseka kristalo wamadzimadzi mu bokosi lagalasi, kenako n’kuyika ma electrode kuti apangitse kusintha kwa kutentha ndi kuzizira, zomwe zimakhudza kufalikira kwake kwa kuwala kuti kukhale kowala komanso kofooka.

Pakadali pano, zipangizo zodziwika bwino zowonetsera makristalo amadzimadzi zimaphatikizapo Twisted Nematic (TN), Super Twisted Nematic (STN), DSTN (Double layer TN) ndi Thin Film Transistors (TFT). Mfundo zoyambira zopangira mitundu itatuyi ndizofanana, zimakhala makristalo amadzimadzi a matrix osagwira ntchito, pomwe TFT ndi yovuta kwambiri ndipo imatchedwa active matrix liquid crystal chifukwa imasunga kukumbukira.

Popeza ma LCD monitors ali ndi ubwino wokhala ndi malo ochepa, makulidwe a panel ochepa, kulemera kopepuka, chiwonetsero chathyathyathya cha ngodya yakumanja, kugwiritsa ntchito mphamvu zochepa, kusakhala ndi mafunde amagetsi, kusakhala ndi mafunde a kutentha, ndi zina zotero, pang'onopang'ono asintha ma CRT image tube monitors achikhalidwe.

Ma LCD monitors ali ndi njira zinayi zowonetsera: reflective, reflective-transmissive conversion, projection, ndi transmissive.

(1). Mtundu wowala kwenikweni sutulutsa kuwala mu LCD yokha. Umalowetsedwa mu LCD panel kudzera mu gwero la kuwala komwe kuli, kenako kuwalako kumaonekera m'maso mwa munthu ndi mbale yake yowala;

(2). Mtundu wosinthira kuwala ndi kutumiza kuwala ungagwiritsidwe ntchito ngati mtundu wowunikira kuwala pamene gwero la kuwala mumlengalenga lili lokwanira, ndipo pamene gwero la kuwala mumlengalenga silikwanira, gwero la kuwala lomangidwa mkati limagwiritsidwa ntchito ngati kuwala;

(3). Mtundu wa chiwonetsero umagwiritsa ntchito mfundo yofanana ndi ya kusewera makanema ndipo umagwiritsa ntchito njira yowunikira yowonetsera chithunzi chomwe chikuwonetsedwa pa LCD monitor pa sikirini yayikulu yakutali;

(4). LCD yolumikizira imagwiritsa ntchito kuwala komwe kwamangidwa mkati ngati kuwala.
