A LCD yam'manja(Liquid Crystal Display) ndi mtundu waukadaulo wazenera womwe umagwiritsidwa ntchito kwambiri pazida zam'manja monga mafoni am'manja ndi mapiritsi.Ndi chowonetsera chathyathyathya chomwe chimagwiritsa ntchito makristalo amadzimadzi kupanga zithunzi ndi mitundu pazenera.
Zowonetsera za LCD zimakhala ndi zigawo zingapo zomwe zimagwirira ntchito limodzi kupanga zowonetsera.Zigawo zazikuluzikulu zimaphatikizanso chowunikira chakumbuyo, chosanjikiza chamadzimadzi amadzimadzi, fyuluta yamtundu, ndi polarizer.Kumbuyo kwake kumakhala gwero la nyali la fulorosenti kapena la LED (Light-Emitting Diode) lomwe lili kuseri kwa chinsalu, kumapereka kuwunikira koyenera.
Chosanjikiza cha makhiristo amadzimadzi chimakhala pakati pa magawo awiri agalasi kapena pulasitiki.Makristasi amadzimadzi amapangidwa ndi mamolekyu omwe amatha kusintha momwe amayendera pamene magetsi akugwiritsidwa ntchito.Pogwiritsa ntchito mafunde amagetsi m'malo enaake a zenera, makhiristo amadzimadzi amatha kuwongolera kutuluka kwa kuwala.
Mtundu wa fyuluta wosanjikiza umayang'anira kuwonjezera utoto ku kuwala komwe kumadutsa mumadzi amadzimadzi.Zimapangidwa ndi zosefera zofiira, zobiriwira, ndi zabuluu zomwe zimatha kutsegulidwa kapena kuphatikizidwa kuti zipange mitundu yosiyanasiyana.Posintha kukula ndi kuphatikiza kwa mitundu yoyambirira iyi, LCD imatha kuwonetsa mitundu yosiyanasiyana ndi mitundu.
Zigawo za polarizer zimayikidwa kumbali yakunja ya gulu la LCD.Amathandizira kuwongolera momwe kuwala kumadutsa mumadzimadzi, kuwonetsetsa kuti chinsalu chimatulutsa chithunzi chomveka bwino chikawonedwa kutsogolo.
Pamene magetsi akugwiritsidwa ntchito pa pixel inayake paChithunzi cha LCD, makhiristo amadzimadzi mu pixelyo amalumikizana m'njira yoti atseke kapena kulola kuwala kudutsa.Kusintha kwa kuwala kumeneku kumapanga chithunzi chomwe mukufuna kapena mtundu pa zenera.
Ma LCD am'manja amapereka maubwino angapo.Atha kupereka zithunzi zakuthwa komanso zatsatanetsatane, kutulutsa kolondola kwamitundu, komanso malingaliro apamwamba.Kuphatikiza apo, ukadaulo wa LCD nthawi zambiri umakhala wamphamvu kwambiri poyerekeza ndi matekinoloje ena monga OLED (Organic Light-Emitting Diode).
Komabe, ma LCD alinso ndi malire.Nthawi zambiri amakhala ndi ngodya yocheperako yowonera, kutanthauza kuti mawonekedwe azithunzi ndi kulondola kwamtundu amatha kutsika akamawonedwa kuchokera kozama kwambiri.Kuphatikiza apo, zowonera za LCD zimavutikira kuti zikwaniritse zakuda zakuda chifukwa chowunikira chakumbuyo chimaunikira ma pixel nthawi zonse.
M'zaka zaposachedwa, zowonetsera za OLED ndi AMOLED (Active-Matrix Organic Light-Emitting Diode) zatchuka kwambiri m'makampani am'manja chifukwa chaubwino wawo kuposa ma LCD, kuphatikiza kusiyanitsa kwabwinoko, ngodya zowonera, ndi mawonekedwe ocheperako.Komabe, ukadaulo wa LCD umakhalabe wofala m'ma foni ambiri, makamaka pazosankha zokomera bajeti kapena zida zomwe zili ndi zofunikira zowonetsera.
