Txoj Haujlwm Coj Yooj Yim Thiab Txheej Txheem Ntau Lawm Ntawm Lub Teeb Qhia Phaj Ntsig

Lub sij hawm lub teeb qhia lub teeb phaj los ntawm lus Askiv cov lus sib dhos (Cov Lus Qhia Teeb), uas yog ua thaum thov rau LCD. LCD yog cov khoom lag luam uas tsis muaj cov teeb pom kev zoo.

Txhawm rau tso saib qhov ci ci ntawm LCD, cov khoom yuav tsum muaj qhov backlight module coj los tso saib. Lub teeb qhia lub phaj yog ib qho tseem ceeb hauv kev txhim kho lub teeb liab backlight.

Nws kuj tau pib hloov pauv txawv nrog qhov kev thov rau cov khoom qis.

Kev khiav dej num thiab cov tseev kom muaj ntawm daim phiaj coj teeb

Raws li lub npe tau qhia, txoj haujlwm tseem ceeb ntawm lub teeb qhia lub teeb yog kom coj lub teeb nyob rau hauv cov kev taw qhia xav tau los ntawm tus tsim, thiab txhua tus qauv tsim ntawm daim phiaj qhia teeb yog

Yuav kom ua tau raws li cov kev xav tau ntawm cov khoom lag luam hauv nqes LCD thiab backlight module, qhov tseem ceeb tshaj plaws yog kom ua tiav qhov ci ci thiab kev tsis sib thooj.

Kev faib tawm ntawm cov paib qhia coj ua

Feem ntau hais lus, cov lus qhia coj teeb muaj ntau hom kev sib txawv vim lawv cov qauv, cov qauv kev ua haujlwm thiab cov haujlwm, thiab tam sim no tsis muaj kev sib koom ua ke. Tom qab txheeb:

1. Raws li cov duab, nws muab faib ua: daim tiaj tiaj thiab cov npoo npoo (phaj inclined)

Tiaj tus phaj: Daim phiaj qhia teeb lub teeb yog duab plaub thaum pom los ntawm lub teeb meem.

Npoo phaj: Los ntawm cov teeb meem ntawm lub teeb, ib sab yog tuab thiab lwm sab yog nyias thiab npoo zoo li (daim duab peb sab).

2. Raws li cov txheej txheem dot ntau lawm: luam ntawv thiab tsis luam ntawv

Kev luam tawm: Tom qab lub teeb qhia lub phaj ua tiav cov duab ua tiav, cov dots tau sau rau ntawm lub ntsej muag los ntawm kev luam ntawv, thiab nws tau muab faib ua ob hom: IR thiab UV.

Hom tsis luam ntawv: cov dots tau ncaj qha tsim nyob rau hauv daim duab ntsej muag thaum lub teeb qhia daim phiaj ua. Nws tau muab faib ua tshuaj etching (Etching), precision tshuab ua cim (V-txiav),

Stamper, sab hauv diffusion.

3. Raws li lub teeb pom kev nrog cov lus qhia: sab tawm tswv yim (lub teeb thiab LED) thiab hom teeb ci ncaj qha.

Sab-lub teeb hom: Muab lub luminous lub cev (raj lossis LED) nyob rau sab ntawm lub teeb qhia daim phiaj.

Hom ncaj qha: Tso lub cev luminous (raj lossis LED) hauv qab cov lus qhia teeb.

4. Raws li cov qauv txheej txheem: kev txhaj tshuaj thiab kev txiav txim siab.

Kev txhaj tshuaj moulding: Siv kev txhaj tshuaj molding tshuab txhaj tshuaj tiv thaiv qib qib PMMA hais ua qhov pwm ntawm qhov kub thiab siab siab kom txias thiab zoo.

Txiav thiab sib sau ua ke: Optical qib PMMA thawj pawg thawj coj yog txiav kom tiav cov khoom tiav.

Lub teeb coj qhia cov phaj tsim cov txheej txheem

Ua ntej nkag siab txog kev ua txheej txheem, koj yuav tsum xub nkag siab cov ntu thiab cov khoom siv uas yuav tsum muaj rau daim phiaj qhia teeb

1. Cov khoom siv thiab cov cuab yeej xav tau

a. Kev txhaj tshuaj molding: optical qib PMMA hais, number case

b. Txiav: optical qib PMMA phaj, number case

2. Optical qib PMMA hais thiab phaj:

Tsis muaj teeb meem dab tsi txog cov qauv kev siv, cov tseem ceeb tshaj plaws thiab cov khoom qub ntawm lub teeb coj qhia yog phaj qib PMMA.

(POLYMETHYL METHACRYLATE) (Polymethacrylate kuj tseem paub zoo li acrylic lossis plexiglass, thiab nws cov kev faib tawm muaj

PMMA hais thiab PMMA daim hlau PMMA yog ua kom zoo zoo los ntawm roj av monomers (MMA) thiab tom qab ntawd cov monomers (MMA) muaj tshuaj kho los ua lub ci ci

Tsev kawm ntawv-qib PMMA hais (rau kev txhaj tshuaj molding twb tau muaj lawm), thiab tom qab ntawv ces qhov kho qhov muag-qib PMMA tau raug muab pov lossis rho tawm

(Txhaj) los tsim kho qhov muag-qib PMMA tiaj tiaj. Cov tuam txhab PMMA pom tau lees paub los ntawm kev lag luam muaj raws li hauv qab no: (Nyiv) Mitsubishi Rei

Yang Mitsubishi Rayon, (Japanese) Sumitomo Tshuaj Sumitomo, (Japanese) Asahicasei, (Japanese) Kuraray, (Taiwan)

Chi Mei Tshuaj, (Han) Shi thiab Sehwa,

3. Ink: muab faib ua UV thiab IR

4. Cov txheej txheem ntau lawm ntawm cov tiaj tiaj txiav lub teeb qhia phaj tau muab faib ua peb ntu:

Thawj yog qhov txheej txheem duab ntawm acrylic ntawv;

Qhov thib ob yog tshuaj ntsuam ntau lawm;

Qhov thib peb yog luam ntawv, thiab txheej txheem ntws yog

a. Acrylic zoo nkauj ua=thawj tswj txiav> daim phiaj phiaj xwm iav> kev ua cov ntaub ntawv.

b. Tshuaj ntsuam ntau lawm=dot tsim> zaj duab xis tso zis> Zhang net

c. Luam Ntawv=Acrylic tu> luam ntawv> ci (IR) lossis ultraviolet lub teeb (UV)

5. Kev txhaj tshuaj molding lub teeb qhia phaj tau muab faib ua hom luam ntawv thiab hom tsis-luam ntawv, thiab cov txheej txheem yog qhov zoo ib yam, vim tias hom luam ntawv tsis nyob hauv kev txhaj tshuaj thaum lub pwm tawg.

Cov dot tau pov rau ntawm qhov screen, yog li cov khoom tiav tiav tsuas yog ua cov duab acrylic. Tom qab cov qauv tsim, daim qhia coj lub teeb yog ua tiav los ntawm luam ntawv. Hom tsis luam ntawv yog tus

Cov qauv tsim tau pov rau ntawm lub pwm kom qhov dots thiab lub teeb coj qhia teeb ua tiav tib lub sijhawm thaum txhaj tshuaj molding.

Kev tsom xam ntawm kev tsim thev naus laus zis ntawm lub teeb coj qhia phaj

1. Khoom siv:

Nyob rau tam sim no, cov khoom siv uas siv hauv kev lag luam yog PMMA, tab sis qhov tsis txaus ntseeg ntawm PMMA thiab kev tsis txaus ntseeg tam sim no ntawm MMA monomer ntau lawm muaj peev xwm

Muaj feem ntau tsis txaus nyob rau hauv kev xa khoom, yog li qee cov tuam ntxhab tau pib nrhiav lwm cov khoom siv, vim hais tias cov lus qhia teeb ci yog qhov tseem ceeb ntawm cov teeb ci hauv LCD.

Yog li ntawd, lub teeb xa ntawm cov khoom siv yog qhov tseem ceeb tshaj plaws. Nippon Zeon ntawm Nyij Pooj tau txhawb cov khoom tshiab Zeonor cycloolefin nyob rau hauv xyoo tas los no.

Qhov loj tshaj qhov zoo tshaj plaws ntawm polymer (Cycio Olefins Polymer, COP) cov lus dag hauv nws lub peev txheej qis thiab dej tsis zoo nqus piv rau PMMA, tab sis vim tias Zeonor ua rau

Lub peev xwm ntau lawm ntawm cov khoom lag luam tsuas yog 5,000 metric tons rau ntau xyoo. Yog li no, chav tsev tus nqi yuav luag 4 npaug ntawm PMMA thaum kev lag luam tsis tau txog. Hauv qhov tam sim no ntawm meager profits,

Xav txog Zeonor' s sib tw kom zoo dua rau tus nqi tuaj yeem hais tau tias yog qhov cuav xwm. Acrylic raws thiab cov ntsiab lus tseem ceeb: qhov loj me, daim iav tiav, qhov tseeb ntawm lub cev, lwm yam

Cov khoom siv zoo, khoov siv, txhav.

2. Kev luam ntawv txheej txheem: txheej txheem luam ntawv tau muab faib ua IR thiab UV vim tias nws cov cwj mem qhuav kom qhuav

Kev sib piv ntawm IR thiab UV luam tawm cov yam ntxwv

3. Txoj kev ua qauv:

Muab faib ua peb hom: txiav luam ntawv, txhaj tshuaj molding luam ntawv thiab txhaj tshuaj moulding uas tsis yog luam ntawv
