Zaub Yam Ntxim Saib Ntxim Saib Ntxim Ua Ntawm Rugged LCD Hauv Kev Kub Siab

Nov 25, 2017

1. Txiav txim siab simulation simulation

Raws li txoj cai ntawm LCD zaub, lub transmittance ntawm LCD yog T, xws li formula (1):

Hauv formula (1), n nruab nrab ntawm cov khoom ntawm LC, D said lub thickness ntawm cov kua siv lead ua kua, ib qho sawv cev ntawm lub wavelength ntawm lub teeb, azimuth kaum ntawm cov kua siv lead ua kua molecules rau psi. Nws tuaj yeem pom los ntawm cov mis uas lub teeb hloov ntawm qhov ncaj qha ntsig txog cov pa ntawm cov kua siv lead ua kua D. Nyob rau hauv daim ntawv no, peb sim ua kom muaj kev hloov pauv ntawm cov kua siv lead ua los ntawm Mura zaub cheeb tsam ntawm LCD npo hauv qab kub thiab quab yuam ntawm thermodynamic simulation thiab xyaum ua tej yam, kom paub ntxiv txog kev sib raug zoo ntawm Mura zaub phenomenon thiab ua kua dej ua paug hloov plawg. Lub qhov cuab lub pob txhawb nqa yog tau los ntawm kev ruaj ntseg ntawm lub npo LCD nrog lub iav uas muaj zog, thiab cov qauv simulating lub caij simulation hauv daim duab 1:

Nws mas suav nrog kev tswj iav, qhov muag pleev qhov muag, sab sauv polarizer, CF substrate, kua siv lead ua kua, TFT substrate thiab qis ncov qaum. Vim tias cov thermodynamic tsis txog txhua feem puas nyuaj rau ntsuas ntawm nws tus kheej, cov cheebtsam yog sib npaug, thiab cov thermodynamic tsis ntawm txhua feem yog tau los ntawm kev sim kev sim thiab kev xeem simulation simulation. Cov lus 1 muab cov thermodynamic tsis txog txhua lub hauv cov qauv simulation, uas cov LCD1 thiab LCD2 yog tib qhov kev ua tsis, cov kua siv tshuaj pleev ua kua los ntawm txawv manufacturers, E x , E y , E z yog cov ywj siab modulus ntawm X, Y thiab Z feem. Lub txaj modulus ntawm X Y , G xz thiab G li yog G, X Z thiab Y Z , thiab qhov coefficient ntawm thermal expansion yog lub coefficient ntawm thermal expansion.

Lub caij nyoog simulation simulation software yog siv los simulate tus npo LCD thiab tus npo LCD, raws li kev thaij thiab kev sib txuas ntawm kev pom zoo hauv daim duab 2:

Noj LCD 1 ua piv txwv. Daim duab 3 qhia tau hais tias ntawm qhov kub ntawm 22 ° C thaum qhov nro 12N LCD thawj LCD npo npo thiab qhov txheej txheem tha xim (Mpa) qhov chaw faib daim ntawv qhia thiab 70 degrees hauv cheeb tsam ntawm kev nruj yog 12N LCD kua siv ua kua nplaum siab (Mpa) pom nyob rau hauv cov kua hluav taws xob puag ncig thawj lub nplhaib thiab kev siv zog ci thaj tsam ntawm kev nyuaj siab thiab kev txhawb zog, nyob hauv kev kub ntxhov siab nce siab.

Nws tuaj yeem pom ntawm cov mis (1) tias lub thickness ntawm cov kua siv lead ua kua muaj ib qho kev sib tw rau ntawm kev xa tawm ntawm lub teeb ntawm ntau lub wavelengths. Lub plhaub (thickness change value) (hli) ntawm lub LCD txheej 1 thiab LCD txheej 1 ntawm lub LCD screen nyob rau hauv qhov kev txiav txim ntawm 12N rub lub zog ntawm 70 degrees ntawm qhov kub tau qhia nyob rau hauv daim duab 4:

Raws li cov simulation tau, nws yuav pom tau tias qhov kev nyuab siab concentration ntawm cov kua siv lead ua kua thiab qhov kev tiv thaiv ua kua dej ua siv zis ncig lub nplhaib thiab lub ntug ntawm lub khob iav, thiab lub thickness ntawm cov kua siv lead ua kua tau pom tseeb, nyob hauv kev hloov ntawm kev xa xov ntawm txhua lub wavelength tsis zoo sib xws, yog li ntawd los tshwm Mura. Lub thickness ntawm cov kua siv lead ua kua rau ntawm ntug ntawm lub khob iav pob zeb yog tau ntawm qhov qub thiab siab kub nrog nce ntawm lub tensile quab yuam los ntawm simite caij simulation, raws li pom hauv cov duab 5 thiab 6:

Raws li cov saum toj kawg nkaus simulation pom tau tias cov kua siv lead ua kua thickness tsub kom nce ntawm nro, thiab los ntawm cov saum toj ob daim duab tuaj yeem pom, tib yam sab nraud, cov kua siv lead ua txheej thickness cov kua siv lead ua plaster txheej ntau dua li daim tseem LCD npo 1 LCD npo ntawm thawj 2, thiab kev kho cov cuab yeej tshiab thiab chaw kub kub yuav ua rau cov kua hloov ua kua ua kom lub thickness nce ho. Yuav kom tshawb tau qhov sib txawv ntawm qhov kev hloov ntawm tib lub ntsuas kub ntawm cov kua hluav taws xob sib txawv hauv cov ntxaij lim dej, cov kua siv lead ua kua hloov ntawm 70 degrees thiab cov kua siv lead ua kua hloov ntawm 22 degrees yog rho tawm kom tau cov ntaub ntawv qhia hauv daim duab 7:

Qhov sib txawv ntawm cov kua siv lead ua kua txheej ntawm cov kua siv ua kua thiab lub siab kub thaj yog nruab nrab ntawm 14nm thiab 58nm, hos qhov sib txawv ntawm cov txheej hauv LCD hauv chav nyob thiab qhov chaw kub siab yog nruab nrab ntawm 80nm thiab 223nm. Yog li, piv nrog cov npo LCD, qhov kev yees qhov cuab lub zog yog qhov hloov ntawm qhov chaw kawm sab nrauv, thiab qhov sib txawv ntawm cov npo LCD sab nraud txawv dua.
