Wadahadaladii u dambeeyay ee warshadaha ayaa dhex galay farsamada asaasiga ah eeTransistor-Filim khafiif ah (TFT) lbandhigyo crystal iquid, iftiiminaya habka ay gacanta "matrix firfircoon" awood sawir-sax-saxsan-horumar cilmi ah oo wadista waayo-aragnimo muuqaal casri ah.
TFT. Si ka duwan bandhigyada caadiga ah, pixel kasta oo aTFTShaashadda si gaar ah ayaa loo xakameeyaa iyada oo loo marayo nidaamka "matrix firfircoon". Mabda'a shaqadu wuxuu u eg yahay habka "shutter": adeegsiga tignoolajiyada iftiinka dambe, transistor-ka u heellan ee ka dambeeya pixel kasta ayaa nidaamiya gudbinta iftiinka iyadoo la adeegsanayo isku-dheellitirka kristaalka dareeraha ah, gaaritaanka midabka saxda ah iyo soosaarka dhalaalka.
Sixirka eeMuraayadaha Crystal dareere ah (LCDs)waxay ku jirtaa sifooyinka gaarka ah ee kiristaalo dareeraha ah. Ka jira saddex dawladood oo aasaasiga ah-smectic (lakab-dhoobo u eg), nematic (molecules-ulaha usha leh), iyo kolesteric (spiraal-qaabaysan)LCD-yada TFTinta badan waxay isticmaalaan kiristaalo nematic. Marka danab la isticmaalo, kiristaalo-yadani waxay leexiyaan jihadooda molecular si ay u xakameeyaan marinka iftiinka. Pixel kastaa wuxuu isku daraa casaan, cagaar, iyo buluug subpixels, isagoo ka faa'iidaysanaya isku darka midabaynta si loo soo saaro muuqaal firfircoon.
Nematic-ka qalloocan (TN) ee si weyn loo qaatayTFT LCDtignoolajiyada, oo caan ku ah jawaab celinteeda degdega ah iyo isku halaynta, waxay awood u siisaa aaladaha caadiga ah ee casriga ah ilaa TV-yada. Sida hal-abuurnimada soo bandhigida dabacsani hore u socoto, TFT waxay diyaar u tahay inay wax ka beddesho beeraha soo ifbaxaya sida tignoolajiyada la xidhi karo, ballanqaad khafiif ah, shaashado qalloocan oo loogu talagalay codsiyada soo socda.
