Mfundo yayikulu ndikusindikiza kristalo wamadzi mu bokosi lagalasi, kenako ndikuyika maelekitirodi kuti apange kusintha kotentha ndi kozizira, potero kukhudza kufalikira kwake kuti kukhale kowala komanso kocheperako.

Pakadali pano, zida zodziwika bwino za kristalo wamadzimadzi zimaphatikizapo Twisted Nematic (TN), Super Twisted Nematic (STN), DSTN (Double layer TN) ndi Thin Film Transistors (TFT). Mfundo zazikuluzikulu zopangira mitundu itatuyi ndizofanana, kukhala makristasi amadzimadzi amadzimadzi, pomwe TFT ndi yovuta kwambiri ndipo imatchedwa active matrix liquid crystal chifukwa imasunga kukumbukira.

Chifukwa oyang'anira ma LCD ali ndi zabwino za malo ang'onoang'ono, makulidwe a mapanelo opyapyala, kulemera pang'ono, chiwonetsero chalathyathyathya kumanja, kugwiritsa ntchito mphamvu pang'ono, osagwiritsa ntchito ma radiation a electromagnetic wave, palibe ma radiation yotentha, ndi zina zambiri, asintha pang'onopang'ono zowunikira zachikhalidwe za CRT.

Oyang'anira LCD amakhala ndi mitundu inayi yowonetsera: kutembenuka, kuwunikira-transmissive transmissive, projection, and transmissive.

(1). Mtundu wowunikira kwenikweni sutulutsa kuwala mu LCD yokha. Amalowetsedwa mu gulu la LCD kudzera mu gwero la kuwala komwe kuli, ndiyeno kuwala kumawonekera m'maso mwa munthu ndi mbale yake yowunikira;

(2). Mtundu wosinthika wowonetserako ukhoza kugwiritsidwa ntchito ngati mtundu wowonetsera pamene kuwala kwa mlengalenga kuli kokwanira, ndipo pamene kuwala kwa mlengalenga kumakhala kosakwanira, kuwala komwe kumapangidwira kumagwiritsidwa ntchito ngati kuunikira;

(3). Mtundu wa pulojekiti umagwiritsa ntchito mfundo yofanana ndi ya kusewera kwa kanema ndipo imagwiritsa ntchito makina owonetsera kuti awonetse chithunzi chowonetsedwa pa LCD monitor pa sikirini yaikulu yakutali;

(4). LCD yopatsirana imagwiritsa ntchito gwero lowala lomwe limapangidwira ngati kuyatsa.
