YUAV UA LI CAS RAU HAUV LUB LCD?

YUAV UA LI CAS RAU HAUV LUB LCD?

Lub Backlight yog lub teeb ci ntawm Liquide Crystal Display Panel.

Qhov Backlight no tsuas yog lub teeb pom kev zoo rau cov duab uas tshwm sim hauv LCD TVs, Laptop zaub, saib, thiab xov tooj ntawm tes.

Hauv cov thev naus laus zis tshiab, LCD Panels 'lub teeb qhov chaw yog LED backlights muab tso rau hauv qab ntawm lub vijtsam.

Hauv cov duab nyias, LED strips muab tso rau ntawm cov npoo ntawm lub teeb -ua iav.

Tsis tas li ntawd, qub - qauv qhia siv high- cov roj fluorescent raj ua lub teeb ci.Peb nkag siab tias Backlight tau muab tso rau hauv qab ntawm LCD vaj huam sib luag.

Tam sim no, peb yuav kawm txog cov qauv sab hauv ntawm LCD vaj huam sib luag saum Backlight.

VERTICAL POLARIZER ua dab tsi hauv LCD?

Polarizer yog dab tsi?

Lub polarizer tsis yog cov khoom siv hluav taws xob. Nws yog tsim los ntawm PVA (Polyvinyl Cawv), ib daim ntawv polarizingfilm, lossis Polarizing Filter rau LCD panels.

Raws li lub teeb los ntawm Backlight dhau los ntawm LCD vaj huam sib luag, nws ntsib lub lim polarizing.

Cov lim no tsuas tso cai rau lub teeb tsis dhau mus, oscillating hauv ib qho kev taw qhia tshwj xeeb.

Qhov no yuav pab kom lub teeb yog polarized ua ntej interacting nrog cov kua muaju.

Lub polarizer ntsug hauv LcD (Liquid Crstal Displav) vaj huam sib luag tswj cov kev taw qhia ntawm lub teeb dhau los ntawm

zaub, nws yog ib qho ntawm cov lim dej polarizing siv hauv kev sib txuas nrog lwm tus hauv cov qauv displav

Hauv LCD, lub teeb hla dhau ntau txheej, suav nrog cov polarizers thiab cov kua siv lead ua kua molecules, los tsim cov duab koj pom.

Vertical polarizer tso cai rau lub teeb nthwv dej oscillating vertically hla dhau thaum thaiv cov oscilating horizontally.

Qhov kev tswj hwm ntawm lub teeb no pab tswj cov kev taw qhia ntawm cov kua siv lead ua kua molecules nyob rau hauv cov zaub, yog li tiv thaiv tus nqi thiab xim ntawm lub teeb uas thaum kawg ncav cuag koj ob lub qhov muag, tsim cov duab thiab hues koj pom ntawm qhov screen.

AVDD STV VGL VCOM VGH hauv LCD vaj huam sib luag yog dab tsi?

TFT yog dab tsi thiab nws ua haujlwm hauv LCD?

TFT sawv cev rau nyias - Zaj duab xis Transistor.

Cov kua siv lead ua kua muaj ntau lab ntawm cov kua siv lead ua kua, txhua qhov uas tau muab los ntawm qhov sib txawv ntawm qhov yuav tsum tau ua los ntawm cov TFTs lossis nyias - zaj duab xis transistors.

Lub TFT substrate isusualy ua los ntawm nyias iav thiab npog nrog ib tug nyias zaj duab xis ntawm semiconductor khoom (TET): cov TETs yog ua los ntawm amorphous silicon.

Lub luag haujlwm tseem ceeb ntawm TFT substrate yog txhawm rau kom tswj tau meej thiab nrawm ntawm txhua pixel ntawm lub vijtsam LCD.

Txhua pixel muaj cov kua siv lead ua kua uas sib xyaw ntawm ob txheej iav.

Lub TFTs ntawm lub substrateact li keyboards uas tswj qhov voltage thov mus rau cov kua siv lead ua kua, txiav txim siab nws kho qhov muag lub xeev (xws li cia lub teeb hla los yog thaiv nws)
