Qhov zoo thiab qhov ci ntsa iab kuj zoo heev
- Apr 25, 2018 -

Lub TFT kua siv lead ua yog muab nrog ib lub semiconductor hloov rau txhua lub pixel, thiab nws cov txheej txheem ua yog zoo li ib qhov loj-thoob kev sib tsuam. Vim txhua pixel tuaj yeem tswj tau los ntawm tus taw tes mem tes, txhua qhov ntawm kuj ywj siab thiab tswj tau tsis tu ncua. Xws li tus tsim tsis tsuas yog txhim kho cov lus teb ntawm kev ceev npo, tab sis tseem muaj peev xwm precisely tswj cov zaub grey nplai, TFT kua muaj kua Crystals Cov xim zoo dua.

TFT (ThinFilmTransistor) yog hais txog tus yeeb yaj kiab nyias, tus txhais tau tias txhua cov kua siv lead ua kua pixel yog tsav los ntawm ib zaj duab xis transistor tom qab nrog ib lub pixel, thiaj li ua kom pom cov ntaub ntawv ceev, high-brightness, high-contrast display screen, thiab nws yog tam sim no qhov zoo tshaj plaws. Yog ib lub LCD xim tso saib, nws cov nyhuv yog ze rau ntawm tus CRT saib, tam sim no lub ntsiab tso saib ntaus ntawv rau cov ntawv cim tseg thiab cov khoom ntiag tug. Txhua pixel ntawm TFT yog tswj los ntawm TFT kev rau nws tus kheej thiab yog ib qho pixel. Yog li ntawd, tsis yog tsuas yog ceev tau zoo heev, tab sis kuj qhov sib piv thiab ci ntsa iab zoo heev, thaum lub sij hawm qhov kev daws teeb meem kuj nce mus txog ib theem siab heev.

TFT-LCD kua Crystal zaub yog ib qho yeeb yaj kiab zaj duab xis transistor hom kua siv lead ua kua, uas yog hu ua "tseeb xim" (TFT). Lub TFT kua Crystal kua muaj ib semiconductor hloov rau txhua pixel. Txhua pixel tuaj yeem tswj tau ncaj qha los ntawm tus taw tes pleev xim. Yog li ntawd, txhua txoj ntawm yog tus neeg ywj pheej thiab tswj tau tsis tu ncua, uas tsis yog pab txhim kho txoj kev kub ceev ntawm qhov kev tshuaj ntsuam, tab sis tseem muaj peev xwm tswj tau cov duab tso tawm. Teeb duab xim, ces qhov xim ntawm TFT LCD yog qhov tseeb tshaj.
