1. Zokhudza LCD (Liquid Crystal Display) Basic Structure
Lumikizanani ndi pepala lachikuto:Malo olumikizira pepala lophimba
Chisindikizo cha LC:Chotsekera chamadzimadzi cha kristalo, choletsa kutayikira kwa madzi a kristalo
Galasi Loyambira:Chitsulo chagalasi chomangirira makristalo amadzimadzi, chokhala ndi TFT pansi pa mbale ndi VCOM/CF pamwamba pa mbale
TFT (Transistor Yopyapyala ya Filimu): Transistor yopyapyala, yomwe ndi yofanana ndi switch, imayang'anira kuyatsa ndi kutulutsa makhiristo amadzimadzi
Matrix Akuda: Matrix wakuda, womwe umatseka TFT yomwe siifunika kukhala yowonekera bwino
Fyuluta ya Mitundu: Fyuluta yamitundu yomwe imasefa kuwala kwachilengedwe komwe kumatulutsidwa ndi kuwala kwakumbuyo kupita ku kuwala kwa R/G/B monochromatic
Crystal Yamadzimadzi: Kristalo wamadzimadzi, chowunikira, momwe gwero la kuwala limafalikira kuchokera pansi kudzera mu kristalo wamadzimadzi.
Electrode Yodziwika:Ma electrode wamba, omwe amapereka mphamvu ya VCOM
Cholumikizira:Chophimba cha gap, chomwe ndi chodzaza, chimagwira ntchito yothandizira kuti gulu lisamire
Chosungira Chosungira:Chosungiramo zinthu (Cs) chomwe chimasunga mphamvu yamagetsi ndikusunga chithunzicho chikuwonetsedwa
Polarizer: Chopolera chomwe chimasefa kuwala kolunjika ndikulola kuwala kofanana kudutsa
Gawo Logwirizanitsa PI: Filimu yolinganiza yomwe imapatsa molekyulu yamadzimadzi ya kristalo ngodya yoyambirira yopotoka, ngodya yoyambirira yopendekera
2. Dongosolo lofanana la TFT-LCD
Clc:Capacitance ya kristalo yamadzimadzi, capacitance yofanana ndi yomwe imapangidwa ndi mamolekyulu a kristalo yamadzimadzi, imalamulira ngodya ya deflection ya mamolekyulu a kristalo yamadzimadzi mwa kusintha mphamvu yamagetsi yomwe imagwiritsidwa ntchito kumapeto onse a Clc (kusiyana kwa voltage pakati pa voltage yoperekedwa ndi Source Driver ndi voltage ya VCOM), motero imasintha transmittance ya kuwala kuti ipereke kuwala kosiyana (gray scale).
Cst:capacitor yosungiramo zinthu, yomwe nthawi zambiri imakhala yayikulu kwambiri kuposa Clc, ndipo imagwiritsidwa ntchito kusunga mphamvu ya Clc; Chifukwa capacitor yamadzimadzi ya crystal ndi yaying'ono, chifukwa cha mawonekedwe a TFT, pali vuto la kutayikira, ndipo Cst capacitor imafunika kuti ipereke chaji yamadzimadzi ya crystal capacitor munthawi yake.
3.Mfundo yoyambira yogwirira ntchito: Scan Driver (yomwe imadziwikanso kuti Gate Driver) imayatsa mzere wa TFT ndi mzere malinga ndi nthawi, ndipo Source Driver imachaja mzere wa Clc ndi Cst ndi mzere malinga ndi nthawi; Mzere uliwonse ukatha kuchajidwa, TFT ya mzere idzazimitsidwa, ndipo gawo lamagetsi la Clc ndi Cst lidzatsekedwa, ndiko kuti, chiwonetsero cha mzerewu chidzamalizidwa. Chitani zomwe zili pamwambapa pa mzere uliwonse kuti mumalize kuwonetsa chophimba chonse cha chimango.
