Lub tswv yim pib ntawm polarising films

 

Muaj pes tsawg leeg ntawm polarizers

  Thawj polarizer yog tsim los ntawm PVA films nrog lub teeb ci tuaj rau hauv nruab nrab, thiab TAV tiv thaiv films rau ob sab. Yuav kom siv thiab tau txais cov teeb meem kho qhov muag sib txawv, tus neeg muag khoom yuav tsum thov lub chaw tsim khoom lag luam hauv LCD los siv lub siab tawv ua ob sab, thiab tom qab ntawd ces muab pov tseg hom yeeb yam, uas yog peb feem ntau TN kev sib pauv kev sib pauv polarizer. Yog tias koj tshem ib txheej txheej tso tawm zaj duab xis, thiab tom qab ntawd ces qhov kev yeeb yaj duab zoo sib xws, nws yog qhov tseem ceeb tshaj plaws ntawm txoj kev xav.
Qhov siv siab rhiab nplaum yog ib qho khoom kub uas tsis muaj zog resistant noo noo resistant rhiab nplaum thiab tshwj xeeb dipping (dye series) rau PVA. Cov ntawv tho polarizing yog hom kub ntau hauv qab ncov qaum. Nyob rau hauv lub siab tawv nplaum, cov ultraviolet rays siv tau los tiv thaiv tau lub UV polarizer. Daim ntawv sib xyaw ua ke ua ke ntawm daim ntawv xa tuaj. Cov khoom siv kho qhov muag yuav ua tau rau hauv lub polarizer rau STN; lub kauj vab kauj cov xim yog ua rau daim ntawv kis tau tus mob, thiab lub polarizer wide lub voj voog lossis lub vos polarizer yuav ua tau. Cov xim ncov qaum cov xim tuaj yeem rau cov xim siv tawv, cov duab PVA lossis TAC movie. Nyob rau hauv qhov tseeb, nrog kev nruam kev loj hlob ntawm cov khoom siv tshiab LCD, hom polarizer tau ua ntau dua.

1.Cov ntaub ntawv ntawm Polarizing PVA films

   Polarizing zaj duab xis PVA, raws li kev txuas khoom ntxiv, muaj cov yeeb yam nram qab no:
Lub teeb xim: xaiv lub teeb pom kev los ntawm tib qho kev coj ua raws li kev coj ua ntawm kev sib txawv.
Kev ntsuas kub thiab cov av noo: tom qab nqus dej los yog cua sov, ib txoj hlua ntawm lub cev muaj zog yuav muab rov qab los ua ib daim duab ntawm cov roj ntsha hauv lub cev thiab poob qhov xim ntawm lub teeb.
Kev ceev: nws yog ib qho yooj yim uas poob lub selectivity ntawm lub teeb nyob rau hauv qhov kev txiav txim ntawm sab nraud rog.
Kev faib tawm ntawm cov ntsiav tshuaj (polarizing tablets):
Nws yog muab faib ua ke rau hauv lub cev zoo nkauj thiab kub kub raws li kub.
Raws li kev xa mus, nws muab faib rau kev sib txuas zoo tib yam thiab kev sib kis high.
Nws muab faib ua gray thiab dawb polarizer thiab xim ncov qaum xim raws li xim tom qab.
Raws li qhov sib txawv ntawm cov khoom siv kho qhov muag, peb faib nws mus rau txhua qhov kev sib kis, ib nrab kis tau tus mob, ib nrab ntawm kev xav, tag nrho cov kev xav, kev kho qhov muag thiab lub hauv kev tswj.


2. Lub ntsiab lus tseem ceeb uas cuam tshuam rau kev ua tau zoo ntawm kev sib tham nrog lub cev:

    Thickness; kev xa tawm (monomer transmittance, parallel transmittance, ntsug transmittance); polarizing efficiency; xim dej num (NBS); zaj duab xis zaj duab xis; UV ua tau linearity.

3. Lub cev tsim kho cov qauv kev ntsuam xyuas thiab cov qauv rau cov duab tho polarizing:

Loj: A, sim txujci: siv tus pas ntsuas, micrometer lossis caliper los ntsuas qhov ntev, qhov dav thiab thickness ntawm tus thawj polarizer.
B, qhov kev txiav txim siab: qhov kev ntsuas no yog tsim nyog rau hauv qhov ntau ntawm cov khoom tsis muab los ntawm tus neeg muag khoom.
Photoelectric zog: A, txuj kev kuaj: lub polarizer yog affixed rau cov khoom thiab kuaj nrog tib hom Polaroid zaj duab xis nrog tib hom khoom.
B, judging standard: Voff tus nqi ntawm qhov kev ntsuam xyuas cov qauv yog sib npaug mus rau Voff tus nqi ntawm cov khoom tsim tawm; qhov zoo sib xws ntawm qhov kev ntsuam xyuas tus qauv yog siab tshaj qhov kev sib piv ntawm cov khoom tsim tawm; qhov kev ntsuam xyuas hauv qab hauv qab yog xim raws li qhov yuav tsum tau tom qab xim.
Kev ntseeg: A, sim txujci: sim lub polarizer rau hauv iav thiab sim cov khoom uas muaj ntsis zoo ib yam li cov qauv coj los sib piv rau nws qhov kev ntseeg tau zoo.
B, judging standard: kev soj ntsuam ntawm kev kho qhov muag thiab hluav taws xob thiab kev cia siab rau qhov kev ntsuam xyuas tom qab kev ntseeg tau zoo sib npaug los ntawm kev soj ntsuam ntawm Polaroid uas zoo sib xws, thiab yog li ntawm cov khoom ntawm tus qauv khoom kuaj.
Muab tshuaj txhuam thiab tev zuag: A, txuj kev sim: muab lub ncov rau ntawm iav, rov ua dua thiab tev nws tawm ob peb zaug.
B, judging standard: nws muaj peev xwm rov qab thiab peeled tshaj peb zaug. Tom qab peb zaug, tsis muaj kua nplaum seem ntawm daim iav. Tom qab cladding, lub nplaum ruaj khov. Qhov defoaming yog tiav raws li qhov tsis tau teev nyob rau hauv ntau lawm, thiab qhov ntsuas kub thiab siab txias siab yog nqa tawm.


4. Cov kev cai xaiv ntawm cov duab tho polarizing:

Qhov nplaim ntawm A + cov khoom yog hauv txoj cai xaiv los ntawm tus thawj polarizer. Qee yam ntawm cov khoom yuav ua tau ntawm TFT optical triangulation. Nyob rau hauv txojcai, tus thawj polarizer yog xaiv.
Lub ntsej muag zaj duab xis ntawm qhov khoom muag A feem ntau yog xaiv los ntawm tus qauv qib siab, TFT tsis muaj daim duab peb sab, los yog ntau dua TFT kaum khoom hauv Tshuag, los yog lub TFT txuas ntawm cov chaw muag khoom tseem ceeb, thiab zaj duab xis nrog lub tseem fwv qib siab.
B qib khoom, kom deb li deb tau siv tsawg Tshuag TFT ntxiv cov khoom ntawm cov khoom laug, daim, los sis tom qab tsis yog lub ntsiab channel siv ntawm TFT ces kaum cov khoom tuaj pauv; zaj duab xis nrog zaj yeeb yaj kiab.
Thaum cov qhua muaj cov kev cai tshwj xeeb, tus tshwj xeeb polarizer yuav tsum raug xaiv raws li tus neeg yuav tsum tau ua.

5. Kev siv roj ntsiav tshuaj:

Tsis txhob tso cov khoom nyhuv ntawm qhov chaw.
Koj tsis tuaj yeem quav nws thaum koj noj.
Xim nees yuav tsum tau ua ntej yuav tsum tau muab tso rau hauv thiab muab cov khoom tso rau sab nrauv.
Thaum ua cov khoom ua si, nco ntsoov tias cov kua residual nyob rau ntawm qhov chaw ntawm lub laujkaub tas li kom txog thaum lub tshuab tuaj yeem ua ke.
Lub ultra wide polarizer yuav tsum tau muab tso rau hauv qab thaum cov kua nplaum.

6. Kev khaws thiab tuav kev ntawm Polaroid:

Cia txoj kev ntawm lub ncov qaumteb qabteb:

Lub ncov qab zib yuav tsum muab cia rau hauv qhov chaw sov li chav nyob, thiab qhov av qis tshaj 75% los tiv thaiv lub teeb.

Tus tuav txoj cai ntawm Polaroid:

         Lub ncov qaumteb qab zib yuav tsum muab tso rau saum lub tshuab xa khoom. Qhov siab yuav tsum tsis txhob siab tshaj qhov siab, thiab nws yuav tsum maj mam daws.
