About LCD (Liquid crystal display)Mawu Otsogolera

1. About LCD (Liquid Crystal Display) Basic Structure

Mapulogalamu a LCD ndi ambiri, (1)

Kulumikizana ndi Tsamba lachikuto:Malo omangirira pa pepala loyambira

LC Chisindikizo:Liquid crystal sealant, anti-liquid crystal kutayikira

Galasi gawo lapansi:Gawo lagalasi lomangira makhiristo amadzimadzi, okhala ndi TFT pa mbale yapansi ndi VCOM/CF pa mbale yapamwamba.

TFT (Thin Film Transistor): Transistor yakanema yopyapyala, yomwe ili yofanana ndi chosinthira, imawongolera kulipiritsa ndi kutulutsa makhiristo amadzimadzi.

Black Matrix: Black matrix, yomwe imatchinga TFT yomwe sifunikira kuwonekera

Zosefera zamitundu: Zosefera zamtundu zomwe zimasefa kuwala kwachilengedwe komwe kumatulutsidwa ndi nyali yakumbuyo mu R/G/B kuwala kwa monochromatic

Crystal yamadzimadzi: Liquid crystal, sing'anga yowonekera, momwe gwero lowunikira limafalikira kuchokera kumunsi kwa gawo lapansi kudzera mumadzi amadzimadzi.

Common Electrode:Ma electrode wamba, omwe amapereka voteji ya VCOM

Spacer:Gap sub, filler, imagwira ntchito yothandizira kuti Panel isamire

Capacitor yosungirako:Chosungira chosungira (Cs) chomwe chimasunga magetsi amagetsi ndikusunga chithunzicho

Polarizer: Polarizer yomwe imasefa kuwala kwa perpendicular ndikulowetsa kuwala kofananira

PI Alignment Layer: Kanema wowongolera omwe amapatsa molekyulu yamadzimadzi kukhala ndi ngodya yokhotakhota, ngodya yoyambira

Mapulogalamu a LCD ndi ambiri, (2)

2. TFT-LCD yoyambira yofanana yozungulira

Clc:Liquid crystal capacitance, mphamvu yofanana yopangidwa ndi mamolekyu amadzimadzi amadzimadzi, imayang'anira momwe mamolekyu amadzimadzi amadzimadzi amadzimadzi amawongolera posintha gawo lamagetsi lomwe limagwiritsidwa ntchito kumapeto onse a Clc (kusiyana kwamagetsi pakati pa voteji yoperekedwa ndi Source Driver ndi voteji ya VCOM. ), potero amasintha ma transmittance of light kuti awonetse kuwala kosiyana (imvi).

Cst:yosungirako capacitor, yomwe nthawi zambiri imakhala yokulirapo kuposa Clc, ndipo imagwiritsidwa ntchito kusunga mphamvu ya Clc; Chifukwa madzi a crystal capacitor ndi ochepa, chifukwa cha makhalidwe a TFT, pali vuto lotayira, ndipo Cst capacitor imayenera kulipira madzi a crystal capacitor mu nthawi.

3.Basic ntchito mfundo: Scan Driver (yemwe amadziwikanso kuti Gate Driver) amayatsa mzere wa TFT ndi mzere malinga ndi nthawi yake, ndipo Source Driver amalipira Clc ndi Cst mzere ndi mzere malinga ndi kutsatizana kwa nthawi; Pambuyo pa mzere uliwonse, TFT ya mzere idzazimitsidwa, ndipo gawo lamagetsi la Clc ndi Cst lidzatsekedwa, ndiko kuti, chiwonetsero chazithunzi cha mzerewu chidzatsirizidwa. Chitani zomwe zili pamwambapa pamzere uliwonse motsatizana kuti mutsirize chiwonetsero chazithunzi zonse.
