Internal Structure Ntawm LCD Vaj Huam Sib Luag Thiab Nws Kev Ntsuam Xyuas

Internal qauv ntawm LCD vaj huam sib luag thiab nws cov kev tsom xam

Dab tsi yog qhov ua haujlwm ntawm lub teeb nraub qaum ntawm 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 cov xov tooj ntawm tes.

Hauv cov thev naus laus zis tshiab, LCD Panels 'lub teeb ci 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, cov khoom qub - qauv qhia siv high-voltage fluorescent raj ua lub teeb ci.

Peb nkag siab tias lub teeb rov qab tau muab tso rau hauv qab ntawm lub vaj huam sib luag LCD. Tam sim no, peb yuav kawm txog cov qauv sab hauv ntawm LCD vaj huam sib luag saum lub teeb nraub qaum.

2. Vertical Polarizer

Dab tsi yog qhov ntsug polarizer ua 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 zaj duab xis polarizing, los yog 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 yog 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 cuam tshuam nrog cov kua siv lead ua kua.

Vertical polarizer nyob rau hauv lub LCD (Liquid Crystal Display) vaj huam sib luag tswj cov kev taw qhia ntawm lub teeb dhau los ntawm cov zaub. Nws yog ib qho ntawm cov lim dej polarizing siv nrog rau lwm tus hauv cov qauv duab.

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 kom dhau los ntawm thaum thaiv cov oscillating horizontally. Qhov kev tswj hwm ntawm lub teeb no pab tswj cov kev taw qhia ntawm cov kua siv lead ua kua molecules 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.

3. TFT (Thin Film Transistors) Substrate

TFT yog dab tsi thiab nws txoj haujlwm hauv LCD?

TFT (Thin{0}}Film Transistor) substrate yog qhov tseem ceeb hauv LCD thev naus laus zis. Nws ua haujlwm ua lub hauv paus lossis txheej txheej rau nyias - zaj duab xis transistors uas tswj tus kheej pixels ntawm cov zaub. TFT substrate feem ntau yog ua los ntawm iav thiab coated nrog nyias zaj duab xis ntawm semiconductor cov ntaub ntawv, xws li 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. TFTs ntawm lub substrate ua raws li cov keyboards uas tswj qhov voltage thov rau cov kua siv lead ua kua, txiav txim siab nws lub xeev kho qhov muag (xws li cia lub teeb hla los yog thaiv nws).

Los ntawm kev siv nyias zaj duab xis transistors, TFT substrate tso cai rau kom muaj tseeb thiab nrawm dua ntawm tus kheej pixels dua li cov lus qhia passive matrix. Qhov no ua rau cov duab zoo dua qub, lub sijhawm teb luv dua, thiab kev ua tau zoo tag nrho hauv cov ntxaij vab tshaus LCD niaj hnub, ua rau lawv haum rau ntau yam kev siv xws li khoos phis tawj, TVs, thiab cov khoom siv mobile.

4. Liquid Crystals Substrate:

Lub luag haujlwm ntawm cov kua siv lead ua kua hauv LCD yog dab tsi?

LCD panels muaj cov kua siv lead ua kua substrate thiab lwm txheej.

Cov txheej no muaj ntau txhiab lab cov kua siv lead ua kua cell raws li qhov screen daws teeb meem.

Txhua lub xov tooj ntawm tes muaj ob lub electrodes, qhov zoo davhlau ya nyob twg AVDD thiab qhov tsis zoo davhlau ya nyob twg VCOM voltage mov, los qhib nws.

Cov kua nplaum yog cov khoom siv tshwj xeeb uas txav lawv cov molecules los ntawm ntsug mus rau kab rov tav thaum muaj zog thiab de{0}}energized.

Cov℃uas lawv txav mus los yog nyob ntawm tus nqi ntawm AVDD, VCOM, thiab teeb liab voltage.

Cov kua dej ua kua hauv lub vaj huam sib luag Liquid Crystal Display ua lub luag haujlwm tseem ceeb hauv kev tswj lub teeb pom kev.

Cov crystals no muaj cov khoom uas tso cai rau lawv hloov lawv txoj kev taw qhia thaum siv hluav taws xob tam sim no.

Cov kua siv lead ua kua ua ke hauv txoj kev tshwj xeeb, tso cai rau lub teeb hla los yog thaiv nws.

Qhov kev siv ntawm lub teeb los ntawm cov kua siv lead ua kua tsim cov duab thiab xim
