Dareere Crystal Display (LCD) waa qalab soo bandhigay isticmaala technology gudbinta kontoroolka crystal dareere si ay u gaadhaan muujinta midabka. Waxay leedahay faa'iidooyinka cabbirka yar, miisaanka fudud, badbaadinta tamarta, shucaaca hooseeya, iyo qaadista fudud, waxaana si weyn loogu isticmaalaa TV-yada, kormeerayaasha, laptops, tablets, smartphones iyo qaybaha kale.Hadda badanshirkadaha heer sare ka gaaray garoonka TV-ga.

Sannadkii 2021, mugga wax-soo-saarka shaashadaha LCD-ga Shiinaha ayaa kor u dhaafay 60% mugga shixnadaha caalamiga ah, taasoo ka dhigaysa Shiinaha kan ugu horreeya adduunka.

LCD-yadu waxay soo bandhigaan sawirro iyagoo ka faa'iidaysanaya sifooyinka kiristaalo dareeraha ah. Waxay isticmaalaan xal kiristada dareere ah oo u dhexeeya laba walxood oo kala sooc ah. Marka korantada korantada ay dhex marto dareeraha, kiristaalo ayaa dib loo habeeyaa si loo gaaro sawirid. Marka loo eego isticmaalka iyo tusmada, LCD-yada waxaa loo qaybin karaa qayb - nooca, dhibicda - dabeecadda matrix - nooca iyo dhibic - garaafyada matrix - nooca. Marka loo eego qaab-dhismeedka jireed, waxay u qaybsan yihiin TN, STN, DSTN iyo TFT. Waxaa ka mid ah, TFT - LCD waa aaladda bandhigga caadiga ah.
