                                                   LCM cov khoom paub yooj yim

1. LC: kua Crystal

Cov dej siv lead ua kua yog ib qho organic compound nrog lub cev molecules txheej txheem ntawm cov khoom thiab kua. Qhov feem ntau siv cov kua siv lead ua kua yog nematic kua siv lead ua kua. Cov duab ntawm lub molecule yog ib qho bar, thiab qhov ntev thiab dav ntawm cov kua siv lead ua kua yog li ntawm 1nm ~ 10nm. Nyob rau hauv qhov kev txiav txim ntawm cov hluav taws xob txawv, cov kua siv lead ua kua molecules yuav tsum tig los ntawm 90 degrees los ua lub teeb ci. Qhov sib txawv, yog li qhov sib txawv ntawm lub teeb thiab ntxoov ntxoo yog generated nyob rau hauv lub hwj huam ON / OFF, thiab txhua pixel yuav raug tswj raws li lub ntsiab cai thiaj li hais tias cov duab xav tau.

Cov kua siv lead ua kua qauv: ob lub iav substrate yog nruab nrog cov yeeb yaj kiab, ces cov kua siv lead ua yuav raug muab tso rau hauv cov zawj, thiab cov kua tshuaj ua kua molecules ua torsional. Thaum iav substrate tsis ntxiv lub teb hluav taws xob, lub teeb yog muab los ntawm lub phom polarizing nrog kua siv lead ua 90 degrees, los ntawm qis polarizing phaj thiab kua. Lub vaj huam sib luag siv lead ua qhia dawb. Thaum iav substrate yog ntxiv rau cov hluav taws xob, cov kua siv lead ua kua molecules tsim cov kev hloov pauv. Lub teeb yog nyob rau hauv cov thawj coj los ntawm cov kua siv lead ua kua molecular chaw. Lub teeb yog obscured los ntawm qis polarizing phaj, lub teeb yog absorbed thiab lub vaj huam sib luag siv lead ua kua qhia dub. Ua kua dej ua siv ua raws li qhov muaj qhov voltage, yog li ntawd lub vaj huam sib luag los mus ua kom pom cov nyhuv.

Lub yeeb yaj kiab txuam txav ua cov roj ntsha hloov roj ntsha, cov kab hluav taws xob ua yeeb yaj kiab uas yog tsim los ntawm txhua qhov taw qhia pixel, thiab lub raj tshwj xeeb lub teeb yog teeb nyob rau sab nraum qab ntawm cov kua siv lead ua kua. Tus TFT "ua haujlwm" los tswj tus kheej pixels ntawm kev tshuaj ntsuam kom nws yog qhov yooj yim kom paub qhov tseeb xim thiab siab daws teeb meem siv lead ua kua.

2. LCD (kua siv ua kua teeb pom kev) Tus qauv pib

Lub ntsiab ntawm cov kua siv lead ua kua yog:

A, iav substrate: evaporated nrog ib txheej ntawm ITO pob tshab conductive txheej thiab nws daim ntawv nyias tiaj iav;

B, kua siv lead ua kua: lub cev ua kua dej loj;

C, polarizer, kuj hu ua polarizer, yog ua los ntawm cov yas yeeb yaj duab cov khoom uas muaj coxav nrog rau qhov muag kho siab tawv thiab muaj peev xwm muab pov rau ntawm cov kua qaub ntawm cov kua qaub.

Nws tuaj yeem pom los ntawm daim duab uas lub LCD yog kua siv ua kua dej ua los ntawm ob daim iav uas muaj iav rau sab saum toj thiab hauv qab. Lub thawv ntim nrog kua siv ua kua. Lub thawv yog ntim nrog ib cov ntaub ntim khoom siv - roj hmab (feem ntau yog epoxy resin). Ob sab nraum lub npov yog siv nrog lub ncov qaum

3, qhov kev piav qhia ntawm lub npe (LC: kua siv lead ua)

4, LCM lub ntsiab kev qhia

A. Lub kaum sab xis pom yog lub ntsiab ntawm cov kua siv lead ua kua, uas txawv ntawm lwm cov lus. Qhov sib txawv ntawm LCD muaj feem xyuam rau lub kaum sab xis ntawm qhov pom, uas yog, lub kaum sab xis ntawm lub qhov muag, thiab hloov nrog qhov kev hloov ntawm qhov kev soj ntsuam. Piv txwv, ib qho screen tau tsa thiab saib ntawm ib qho chaw siab dua rau qhov zoo tshaj qhov sib txawv, ces qhov screen yog 12 taw tes ntawm saib (thiab 12 point ntawm lub moos yog ib qho ncaj rau); los ntawm ib txoj haujlwm qis dua rau qhov zoo tshaj qhov sib txawv, qhov screen yog 6 point of view (thiab tib lub sij hawm lub moos 6 lub ntsiab lus) ntawm sab laug yog 9 ntsiab lus pom, Txoj cai yog 3 taw tes ntawm saib.

B.Contrast yog hais txog kev sib piv ntawm lub xeev cov zaub (cov ntsiab lus ntawm cov zaub) thiab cov kabmob sib txuas ntawm lub xeev tsis pom (cov xim hauv qab) ntawm cov kua dej ua kua, uas feem ntau yog qhov tseeb ntawm daim duab.

C. Lub sij hawm thaum lub sij hawm ua kua dej siv feem ntau yuav tsum pom cov duab hloov. Lub sij hawm teb ntawm tib neeg qhov muag yog li ntawm kaum tawm milliseconds, yog li qhov lus teb ntawm qhov kev hloov ntawm lub teeb liab mus rau lub teeb liab ntawm qhov yuav tsum tsis txhob qis dua li ntawm qhov kev ceev no.

D. Kev noj tshuaj yog lub zog siv thaum LCD ntsuas haujlwm. Tsawg zog noj yog ib qhov zoo tshaj plaws ntawm LCD. Tag nrho cov kev siv fais fab ntawm LCD nyob ntawm qhov chaw pom, tsav tsheb thiab cov ntaub ntawv xaiv.

E. Cov kev hloov hauv cov yam ntxwv kub kub yuav ua rau qee yam ntawm cov khoom siv ntawm cov khoom siv ua kua, thiab cov yam ntxwv ntawm cov duab LCD ntawm qhov ncaj qha ntsig txog cov teeb meem no, yog li cov kua siv lead ua yuav tsum tau ua hauj lwm hauv ib qho chaw kub npaum li cas. Thaum lub ntsuas kub siab dhau lawm, cov kua siv lead ua kua yuav ploj thiab tsis tuaj yeem tshwm. Thaum twg qhov kub tsis dhau, qhov kev ua teb ceev yuav pom qeeb qeeb kom txog thaum crystallization, ua rau kev puas tsuaj rau LCD. Qhov no yog txiav txim los ntawm cov yam ntxwv ntawm cov khoom siv lead ua kua. Feem ntau cov kua tshuaj siv ua kua dej tau muab faib ua hom (hauv chav kub 0 degrees ~ 50 degrees Celsius) lossis dav hom kub (-10 degrees ~ 60 degrees Celsius).

F.Dynamic cheeb tsam (tsam AA: thaj tsam): zoo duab pom cheeb tsam ntawm LCD

G.Visible thaj av (thaj tsam VA: cheeb tsam pom): pom thaj tsam ntawm LCD,> AA ntawm thaj chaw VA.

H.Interface hom: DRIVER IC interface ntawm TFT npo muab faib rau CPU interface thiab RGB interface. CPU interface xub xa cov duab cov ntaub ntawv rau DRIVER IC tus duab tsis thiab tom qab ntawd qhia txog nws. RGB interface hais txog qhov ncaj qha zaub ntawm duab cov ntaub ntawv tsis muaj duab tsis tuaj.

Tam sim no, CPU interface feem ntau siv.

I.Resolution: txoj kab ntawm lub teeb duab, tus naj npawb ntawm qhov ntsug pixel (pixel), xws li QVGA (240x320), QCIF (176x220) QQVGA (128x160) WQVGA (240x400); tus pixel muaj R, G, B peb sab pixels.

5, kev ntsuam xyuas ntawm cov xwm txheej cuam tshuam rau cov nyhuv ntawm LCM zaub

(1). backlight brightness: zoo backlight brightness thiab uniformity ua cov duab zoo nkauj dua, tab sis ntev li ntawm brightness yuav ua rau lub qhov muag nkees.

(2) lub sijhawm lo lus teb ntawm cov kua siv lead ua kua: lub sijhawm "lub sijhawm teb" yog qhov lus teb ntawm lub LCD rau lub teeb liab, uas yog, kua siv ua kua yog muab los ntawm qhov tsaus lossis lub teeb tsaus. Yeej, qhov me dua qhov "lub sijhawm" qhov kev ntsuas, qhov zoo dua. Thaum lub sij hawm teb me me, tus neeg siv yuav tsis zoo li lub duab ntxoov ntxoo lossis luag thaum saib daim duab thij duab. Feem ntau, txhua yam LCD yuav sib faib ceev ceev rau ob qhov chaw - "Nce" thiab "Poob".

(3) qhov sib txawv thiab qhov kev xav: qhov siab dua qhov zoo sib xws, qhov dav lub kaum sab xis, qhov zoo dua qhov qub.

(4) software debugging: qhov tsis ntawm IC yuav tsum tau hloov mus rau qhov zoo tshaj plaws tus nqi kom phim tus txheeb ze LCD npo, txwv tsis pub yuav muaj ib nrab dawb, dim, jitter thiab thiaj li.

(5) cov nyhuv ntawm cov khoom siv.LCM kuj muaj feem xyuam nrog cov yam xws li xim saturation (gamut), kev daws teeb meem thiab xim xim. Chromatic naj npawb nruab nrab yog cov zauv ntawm cov xim uas tuaj yeem pom nyob rau hauv cov kua siv lead ua pixel. Qhov ntau dua cov xim, qhov zoo dua qhov kev ua tiav ntawm qhov screen. Daim duab high-resolution duab pom tseeb thiab muag heev, thiab hloov tshiab, qhov kev txiav txim siab qhov hnyav dua. Qhov kev daws teeb meem tsis tuaj yeem soj ntsuam ntawm tus naj npawb nkaus xwb, tab sis kuj tseem nrog qhov loj ntawm qhov screen.


xim hauj lwm ( chrominance)   )


a. Cov qauv kev lag luam: CIE 1931.It yog siv los qhia qhov txawv ntawm qhov txawv ntawm cov xim. Cov ntaub ntawv ntawm cov xim sib txawv.
