Hurukuro dzechangobva kuitwa muindasitiri dzakanyatsoongorora tekinoroji huru yeTransistor yeFirimu Tsvuku (TFT) lkuratidzwa kwekristaro yeiquid, ichiratidza nzira yayo yekudzora "active matrix" iyo inobvumira mifananidzo yakanyatsojeka—budiriro yesainzi inofambisa ruzivo rwemazuva ano rwekuona.
TFT, muchidimbu cheThin-Film Transistor, zvinoreva matrix yematransistors madiki. Kusiyana nezviratidzo zvemazuva ano, pixel imwe neimwe iri muTFTSikirini inodzorwa yega yega kuburikidza ne "active matrix". Nheyo yekushanda kwayo yakafanana ne "shutter" mechanism: vachishandisa tekinoroji ye backlight, ma transistors akatsaurirwa ari kumashure kwepikisiki yega yega anodzora kufambiswa kwechiedza nekushandura liquid crystal alignment, zvichiita kuti ruvara rwacho rwuve rwakarurama uye kupenya kubudiswe.
Mashiripiti eMagirazi eLiquid Crystal Displays (LCDs)iri muhunhu hwakasiyana hwemakristaro emvura. Aripo muzvikamu zvitatu zvikuru—smectic (ma layers akafanana nevhu), nematic (mamorekuru akaita setsvimbo), uye cholesteric (yakagadzirwa nespiral)—Ma TFT LCDKazhinji anoshandisa makristaro ane nematic. Kana magetsi ashandiswa, makristaro aya anochinja marongerwo awo emamorekuru kuti adzore kufamba kwechiedza. Pixel yega yega inosanganisa ma subpixel matsvuku, magirini, nebhuruu, zvichiita kuti mavara awedzere kusanganiswa kuti abudise mifananidzo yakajeka.
Twisted Nematic (TN) inoshandiswa zvakanyanyaTFT LCDtekinoroji, inozivikanwa nekupindura kwayo nekukurumidza uye kuvimbika, inosimudzira michina mikuru kubva kumafoni kusvika kumaTV. Sezvo hunyanzvi hwezviratidziro zvinochinjika huchifambira mberi, TFT yakagadzirira kuchinja minda iri kubuda senge tekinoroji inopfekwa, ichivimbisa masikirini akatetepa, anogona kupetwa ekushandisa muchizvarwa chinotevera.
