Qhov txawv ntawm LCD Module thiab LCD vaj huam sib luag yog dab tsi?

Liquid Crystal Module (LCM) tsuas yog lub vijtsam LCD thiab teeb pom kev sib dhos. Piv txwv li, cov khoom vaj huam sib luag ntawm LCD TV yog cov kua siv lead ua kua, thiab nws qhov kub thiab txias yog sib npaug rau lub raj duab hauv CRT. Lwm qhov chaw muaj xws li fais fab mov circuits, teeb liab ua circuits, thiab lwm yam, thiab tau kawg lub casing.

Cov kua siv lead ua kua modules feem ntau muab faib ua cov tshuaj ntsuam thiab cov teeb pom kev zoo. Ob qhov chaw tau sib sau ua ke tab sis ua haujlwm ntawm ib leeg. Lub hauv paus ntsiab lus ntawm cov kua siv lead ua kua yog tias cov khoom siv backlight emits lub teeb, thiab lub teeb pom kev los ntawm cov kua siv lead ua kua screen. Lub luag haujlwm ntawm lub vijtsam LCD yog tswj thiab ua cov teeb no ntawm pixel-los ntawm -pixel hauv paus los tso saib cov duab.

Lub LCD vaj huam sib luag yog lub hauv paus tseem ceeb ntawm LCD thiab suav txog ze li 80 feem pua ​​ntawm cov nqi ntawm LCD. Tam sim no, tsis muaj ntau manufacturers nrog vaj huam sib luag tsim technology nyob rau hauv lub ntiaj teb no. Tsuas yog SHARP (Sharp), Samsung, LGD, Innolux, AUO thiab lwm cov tuam txhab muaj cov thev naus laus zis tseem ceeb. Yav dhau los, feem ntau cov tuam txhab lag luam siv lawv cov LCD panels. Yog lawm, nrog rau kev loj hlob sai ntawm cov tuam txhab loj hauv av, cov tuam txhab hauv tsev xws li BOE, Shentianma, CSOT, thiab lwm yam kuj tau pib sau lawv tus kheej patented thev naus laus zis, thiab cov vaj huam sib luag tsim los ntawm lawv kuj tau siv dav los ntawm cov chaw tsim khoom.

Qhov txawv ntawm LCM thiab LCD vaj huam sib luag yog dab tsi

LCD vaj huam sib luag specifications thiab qib

Qhov li -hu ua pixel tuag yog ib lo lus dav dav rau pixels uas tsis tuaj yeem tso tawm ib txwm nyob ntawm lub vaj huam sib luag LCD. Lub vaj huam sib luag ua kua siv lead ua yog tsim los ntawm ntau cov ntsiab lus pixel, thiab cov khoom siv ua kua siv lead ua kua ntawm txhua qhov chaw pom tau ua tiav los ntawm kev hloov lub teeb xa mus thiab tib lub xeev nyob rau hauv kev tswj ntawm hluav taws xob teeb liab. Ntawm 1024768 daws teeb meem, lub LCD vaj huam sib luag muaj tag nrho ntawm 786,432 cov ntsiab lus tso saib, yog li nws tsis yooj yim los lav tag nrho tias yuav muaj qee qhov teeb meem nrog ntau cov ntsiab lus. Tam sim no, thev naus laus zis tsis tuaj yeem kov yeej qhov tshwm sim tsis muaj pixels tuag. Yog li ntawd, theem faib ntawm lub vaj huam sib luag kuj raug txiav txim raws li tus naj npawb ntawm cov pixels tuag. Cov neeg tsim khoom feem ntau zam cov pixels tuag thiab faib cov LCD vaj huam sib luag, muag LCD vaj huam sib luag uas tsis muaj cov pixels tuag lossis ob peb pixels tuag ntawm tus nqi siab, thaum cov neeg uas muaj ntau cov pixels tuag raug cuam tshuam nrog tus nqi qis.

Tam sim no, cov qauv ntsuas tseem ceeb rau cov panels yog:

Korean manufacturers, tsawg dua 3 yog A-level

Japanese manufacturers, tsawg dua 5 yog A-level

Taiwanese manufacturers, tsawg dua 8 yog Class A

Cov cim tseem ceeb ntawm lub ntsiab LCD saib hom:

AA qib: LCD zaub tsis muaj pixels tuag yog qib AA.

A-theem: 3 tuag pixels lossis tsawg dua, tsis pub ntau tshaj ib qho chaw ci, thiab qhov chaw ci ntsa iab tsis nyob hauv nruab nrab ntawm qhov screen.

Chav B: 3 cov pixels tuag lossis tsawg dua, suav nrog tsis pub ntau tshaj ob qhov chaw ci ntsa iab, thiab qhov ci ci tsis nyob hauv nruab nrab ntawm qhov screen.

Tsis tas li ntawd, qhov zoo ntawm cov kua siv lead ua vaj huam sib luag muaj feem xyuam nrog kev daws teeb meem, ci ntsa iab, lub sij hawm teb, kev pom, qhov sib piv thiab cov zoo li cov kua siv lead ua vaj huam sib luag. Cov kev tswj ICs, cov ntxaij lim dej thiab cov yeeb yaj kiab coj los siv hauv kev tsim cov kua siv lead ua kua vaj huam sib luag yog ze rau qhov sib piv ntawm lub vaj huam sib luag. Rau cov neeg siv zoo tib yam, qhov sib piv ntawm 350: 1 yog txaus, tab sis nyob rau hauv kev tshaj lij, xws li qhov sib piv piv tsis txaus. cov neeg siv xav tau.

Brightness kuj yog qhov taw qhia tseem ceeb dua. Qhov ci ntsa iab ntawm cov kua siv lead ua kua yog, nws sawv tawm ntawm ib kab ntawm cov kua siv lead ua phab ntsa thaum saib los ntawm qhov deb. Lub hauv paus ntsiab lus ntawm LCD zaub ci ci yog pom tau los ntawm qhov ci ntsa iab ntawm lub teeb pom kev hauv qab lub vaj huam sib luag.

Lub sij hawm teb yog hais txog cov lus teb ceev ntawm cov kua siv lead ua kua rau lub teeb liab input, uas yog, lub sij hawm teb ntawm cov kua siv lead ua kua los ntawm tsaus rau ci los yog los ntawm ci mus rau tsaus, feem ntau yog milliseconds (ms). Lub sij hawm teb yog luv li sai tau.

Kev pom lub kaum sab xis ntawm cov kua siv lead ua kua Thaum lub teeb rov qab dhau los ntawm cov polarizer, cov kua siv lead ua kua thiab cov txheej txheem sib dhos, lub teeb tso zis muaj kev taw qhia. Txog tam sim no muaj peb txoj kev nrov dua, xws li: TN ntxiv rau FILM, IPS (IN-PLANE-SWITCHING) thiab MVA (MULTI-DOMAIN VERTICAL alignment).
