Doodaha warshadaha ee dhawaanahan ayaa lagu falanqeeyay tiknoolajiyada ugu muhiimsan eeTransistor-ka Filimada Khafiifka ah (TFT) lBandhigyada kiristaalka iquid, iyagoo iftiiminaya habka xakamaynta "matrix-ka firfircoon" kaas oo awood u siinaya sawir-qaadis sax ah - horumar cilmiyeed oo horseedaya khibrado muuqaal casri ah.
TFT, oo loo soo gaabiyo Transistor-ka Thin-Film, waxa loola jeedaa matrix ah transistors-ka yar yar. Si ka duwan bandhigyada caadiga ah, pixel kasta oo ku jiraTFTShaashadda si gaar ah ayaa loo xakameeyaa iyada oo loo marayo nidaam "matrix firfircoon". Mabda'a shaqadu wuxuu u eg yahay habka "shutter": iyadoo la adeegsanayo tignoolajiyada iftiinka dambe, transistors-ka u heellan ee gadaasha pixel kasta waxay nidaamiyaan gudbinta iftiinka iyagoo maareynaya isku-dubaridka kiristaalka dareeraha ah, iyagoo gaaraya midab sax ah iyo soo-saar dhalaalaya.
SixirkaShaashadaha Dareeraha ah ee Crystal (LCDs)waxay ku jirtaa sifooyinka gaarka ah ee kiristaallada dareeraha ah. Waxay ka jirtaa saddex xaaladood oo aasaasi ah - smectic (lakabyo dhoobo u eg), nematic (molecules qaab u eg), iyo kolestarool (qaab-dhismeed wareegsan) -LCD-yada TFT-gaInta badan waxay isticmaalaan kiristaalo nematic ah. Marka danab la isticmaalo, kiristaalo-yahannadani waxay qalloociyaan jihada molecular-ka si ay u xakameeyaan marinka iftiinka. Pixel kasta wuxuu isku daraa casaan, cagaar, iyo buluug hoosaadyo, isagoo adeegsanaya isku-darka midabyo dheeri ah si loo soo saaro muuqaallo firfircoon.
Nooca Twisted Nematic (TN) ee si weyn loo isticmaaloLCD-ga TFT-gaTiknoolajiyadda, oo loo yaqaan jawaab celinteeda degdega ah iyo isku halaynta, waxay awood siisaa aaladaha caadiga ah laga bilaabo taleefannada casriga ah ilaa TV-yada. Iyadoo hal-abuurka bandhigyada dabacsan uu sii socdo, TFT waxay diyaar u tahay inay kacaan ka dhigto meelaha soo koraya sida tiknoolajiyada la xiran karo, iyadoo ballanqaadaysa shaashado khafiif ah oo la laaban karo oo loogu talagalay codsiyada jiilka xiga.
