Umgaqo osisiseko kukuvala ikristale yolwelo kwibhokisi yeglasi, uze emva koko usebenzise ii-electrodes ukuze zenze utshintsho olushushu nolubandayo, ngaloo ndlela zichaphazela ukuhanjiswa kwayo kokukhanya ukuze kufezekiswe isiphumo esikhanyayo nesifiphele.
Okwangoku, izixhobo eziqhelekileyo zokubonisa i-liquid crystal ziquka i-Twisted Nematic (TN), i-Super Twisted Nematic (STN), i-DSTN (Double layer TN) kunye ne-Thin Film Transistors (TFT). Imigaqo esisiseko yokuvelisa ezi ntlobo zintathu iyafana, iba zii-passive matrix liquid crystals, ngelixa i-TFT iyinkimbinkimbi ngakumbi kwaye ibizwa ngokuba yi-active matrix liquid crystal kuba igcina inkumbulo.
Ngenxa yokuba iimonitha ze-LCD zineengenelo zendawo encinci, ubukhulu bepaneli encinci, ubunzima obuphantsi, isibonisi esithe tyaba se-engile yasekunene, ukusetyenziswa kwamandla aphantsi, ukungabikho kwemitha ye-electromagnetic wave, ukungabikho kwemitha ye-thermal, njl.njl., ziye zatshintsha ngokuthe ngcembe iimonitha zetyhubhu yomfanekiso ze-CRT zemveli.
Iimonitha ze-LCD ngokusisiseko zineendlela ezine zokubonisa: ukubonakalisa, ukuguqula okubonakalayo, ukuqikelela, kunye nokubonakalisa.
(1). Uhlobo olubonakalisa ukukhanya alukhuphi ukukhanya kwi-LCD ngokwayo. Lufakwa kwiphaneli ye-LCD ngomthombo wokukhanya kwindawo ekuyo, uze emva koko ukukhanya kubonakale emehlweni omntu ngepleyiti yalo ebonakalisa ukukhanya;
(2). Uhlobo lokuguqulwa kokudluliselwa kokukhanya lungasetyenziswa njengohlobo lokukhanya xa umthombo wokukhanya kwindawo wanele, kwaye xa umthombo wokukhanya kwindawo unganelanga, umthombo wokukhanya owakhelwe ngaphakathi usetyenziswa njengokukhanyisa;
(3). Uhlobo lokubonisa lusebenzisa umgaqo ofana nowokudlala iimuvi kwaye lusebenzisa inkqubo yokubonisa umfanekiso oboniswa kwisikrini se-LCD kwisikrini esikhulu esikude;
(4). I-LCD edlulisa ukukhanya isebenzisa ngokupheleleyo umthombo wokukhanya owakhelwe ngaphakathi njengokukhanyisa.
