1. Hais txog LCD (Liquid Crystal Display) Basic Structure
Cover Sheet Tiv tauj:Qhov chaw txuas ntawm daim ntawv npog
LC foob:Ua kua crystal sealant, anti-kua crystal to
iav substrate:Lub iav substrate rau clamping kua muaju, nrog TFT ntawm lub phaj qis thiab VCOM / CF ntawm lub phaj sab sauv
TFT (Thin Film Transistor): Ib zaj duab xis nyias nyias, uas sib npaug rau qhov hloov pauv, tswj kev them nyiaj thiab tawm ntawm cov kua siv lead ua kua
Dub Matrix: Dub matrix, uas thaiv TFT uas tsis tas yuav pob tshab
Xim Lim: Cov xim lim uas lim cov teeb pom kev zoo los ntawm lub teeb rov qab rau hauv R / G / B monochromatic teeb
Crystal kua: Liquid crystal, translucent nruab nrab, nyob rau hauv uas lub teeb qhov chaw yog torsionally kis los ntawm lub substrate los ntawm cov kua siv lead ua kua
Common Electrode:Common electrode, uas muab VCOM voltage
Spacer:Qhov sib txawv sub, muab tub lim, ua lub luag haujlwm txhawb nqa los tiv thaiv lub vaj huam sib luag los ntawm kev poob
Cia Capacitor:Lub chaw cia khoom capacitor (Cs) uas khaws cov nqi hluav taws xob thiab khaws cov duab tso tawm
Polarizer: Ib lub polarizer uas lim tawm lub teeb perpendicular thiab cia lub teeb sib luag los ntawm
PI Alignment Txheej: Ib zaj duab xis sib dhos uas muab cov kua siv lead ua kua molecule pib lub kaum sab xis deflection, lub kaum sab xis pre-inclination
2. TFT-LCD yooj yim sib npaug Circuit Court
Clc:Cov kua siv lead ua kua capacitance, qhov sib npaug capacitance tsim los ntawm cov kua siv lead ua kua molecules, tswj lub deflection lub kaum sab xis ntawm cov kua siv lead ua kua molecules los ntawm kev hloov cov hluav taws xob siv rau ntawm ob qhov kawg ntawm Clc (qhov sib txawv ntawm qhov voltage muab los ntawm Tus Tsav Tsheb thiab qhov voltage ntawm VCOM. ), yog li hloov qhov kev xa tawm ntawm lub teeb mus rau qhov sib txawv ci ntsa iab (grey nplai).
Cst:cia capacitor, uas feem ntau loj dua Clc, thiab yog siv los tswj lub zog ntawm Clc; Vim tias cov kua siv lead ua kua capacitor yog qhov me me, vim yog cov yam ntxwv ntawm TFT, muaj teeb meem to, thiab Cst capacitor yuav tsum tau them cov kua siv lead ua kua hauv lub sijhawm.
3.Lub hauv paus ntsiab lus ua haujlwm: Scan Tsav Tsheb (tseem hu ua Gate Driver) tig rau TFT kab los ntawm kab raws li lub sijhawm, thiab Tus Neeg Tsav Tsheb Them Nqi Clc thiab Cst kab los ntawm kab raws li lub sijhawm ua ntu zus; Tom qab txhua kab raug them, TFT ntawm kab yuav raug muab tua, thiab lub zog hluav taws xob ntawm Clc thiab Cst yuav raug kaw, uas yog, qhov screen zaub ntawm kab no yuav ua tiav. Ua cov haujlwm saum toj no rau txhua kab nyob rau hauv lem kom tiav cov zaub ntawm tag nrho cov ncej screen.
