Ua ntej, kev nthuav tawm ntawm kev lag luam hauv LCD

TFT-LCD (thinfilmtransistor-liquidcrystaldisplay) TFT-LCD tshuab yog ib qho ua ke ntawm microelectronic technology thiab kua siv lead ua kua tshuab. TFT LCD yog pom los ntawm kev kaj siab zoo, kev sib piv siab, kev paub zoo ntawm hierarchy, ci xim, tab sis kuj muaj cov kev tsis haum siab dua.

Lub koob yees duab LCD siv nyob rau hauv TV tsuas yog siv TFT LCD vaj huam sib luag, lub ntsiab yam muaj xws li kev teeb pom kev zoo, kev kos polarizing, xim lim zaj duab xis, iav substrate, zaj duab xis transistor, zaj duab xis xim, kua siv ua kua thiab zoo li ntawd.


Qhov thib ob, kev lag luam hauv nroog LCD nce qib kev lag luam

Xim lim, backlight module, polarizing phaj yog ib qho tseem ceeb ntawm TFT-LCD, qhov tseem ceeb tiv nqi cov nqi them rau qhov ratio ntawm 60% -70%, tus yuam sij rau tswj cov degree ntawm Cheebtsam yog qhov tseem ceeb ntawm txhua lub vaj huam sib luag manufacturers tswj cov kev sib tw, tuav cov ntaub ntawv ruaj khov ntawm cov tuam txhab lag luam xws li AUO, CMO, lub hwj chim siab siab.

(1) iav substrate

Lub iav LCD substrate yog ib qho yooj yim ntawm cov khoom siv ua kua dej, TFT-LCD iav substrate yog ib daim ntawv nyias nyias ntawm iav ntsa zoo heev, cov khoom siv ntawm cov khoom siv ua kua ua kua, nws yog ib qhov tseem ceeb ntawm kev lag luam cov ntaub ntawv tso tawm, dav siv LCD, PC TV, phau ntawv saib xyuas thiab xov tooj ntawm tes. Ntiaj teb TFT-LCD iav substrate tsum yog Corelle of America (Coming) thiab Nyiv Asahi (AsahiGlass), fais fab iav (NEG) thiab Sn (mitechnology) 4.

(2) backlight module

Lub teeb nrig nraim yog ib qho tseem ceeb ntawm cov khoom siv hauv LCD. Qhov kev ua no yog kom muaj kev txaus siab thiab kev sib koom tes ntawm lub teeb ci, kom nws pom tau cov duab txhua zaus. Cov kua siv lead ua kua yog ib qho kev tso pa tawm ntawm lub cev. Cov zaub nws tus kheej tsis tawm lub teeb, tab sis yog qhov teeb pom kev zoo ntawm qhov kev teeb tsa nram qab hauv qab nws. Cov teeb pom kev zoo thiab cov duab LCD ua ke los ua tus qauv ntawm tus qauv LCD. Lub lag luam tseem ceeb ntawm lub teeb nruab nrig yog Taiwan cov tuam txhab, feem ntau yog cov hluav taws xob thiab radiant opto electronics.

(3) polarizing phaj

Lub ntsiab lus ntawm polarizing phaj rau TFT vaj huam sib luag muaj xws li: TAC film (txhawb txheej), PVA zaj duab xis (Pian Guangceng), AG film (anti glare txheej), LR / AR (tsis tshua xav txog / tsis sib luag txheej), PSA (nplaum txheej) , kev tiv thaiv txheej txheem, WVDLC optical compensation film, uas plays lub luag hauj lwm ntawm polarizing phaj preservation thiab kev tiv thaiv kev tiv thaiv. TAC zaj duab xis thiab PVA yog cov yeeb yam tseem ceeb tshaj plaws hauv kev tsim cov yeeb yaj duab polarizing, accounting rau 54% thiab 17% ntawm cov nqi ntawm cov khoom siv coj los ntawm polarizer.

Cov kev tsim technology ntawm polarizer tau monopolized Nyiv, Kaus lim qab teb, Tuam Tshoj, Taiwan thiab lwm lub teb chaws thiab cheeb tsam. Nws yog qhov nyuaj heev rau cov lag luam hauv kev loj hlob los ua cov qauv TFT hom polarizer. Hauv cheeb tsam hauv lub teb ntawm polarizing phaj yog me me, lub ntsiab manufacturers tau Sheng ophotoelectric, peb spectrum, fujihoo electronics, optoelectronics, electronics Wei Xu, muaj hmoo etc ..


Thib peb. Kev ua lag luam loj ntawm lub lag luam LCD

TFT-LCD yuav dav siv nyob rau hauv ntiaj teb xov tooj ntawm tes, ntse tes, desktop computers, laptops, ntsiav tshuaj PCs, zoo li high-txhais / Ultra siab txhais, LCD-TV panels thiab li on.


Qeb plaub, LCD ua qauv lag luam kev lag luam

Cov lag luam tseem ceeb hauv lub ntiaj teb tseem ceeb TFT-LCD lub ntsiab South Kauslim LGDisplay, Samsung, Taipei Innolux Corporation thiab AU Optronics Corp., Nyiv thiab JapanDisplay, BOE Technology Group nyob rau hauv xyoo tas los, kev loj hlob ceev ntawm kev lag luam.

Thib tsib, LCD kev lag luam kev lag luam

LCD saib xyuas kev ua lag luam yog paub tab, hom tshuaj ua lag luam tig mus rau cov khoom tsim kev loj hlob, uas qhov sib txawv ntawm qhov loj loj yog pom tseeb. Nyob rau hauv 2015 Suav lag luam hauv Internet ntawm 32 nti LCD saib xav ntxiv nthuav dav, vim hais tias muaj peev xwm tseem qhib lub vaj huam sib luag qhov chaw tsis muaj kev ntshai, thaum lub 32 nti TV vaj huam sib luag nqi poob, tus nqi qis dua li tam sim no hauv Internet vaj huam sib luag module market mainstream 27 inch, ntau hom ntawm Hoobkas kom tau ib lub TV vaj huam sib luag los ntawm 32 nti LCD saib, uas saib cov khoom xa khoom loj hlob loj tuaj.

Nyob rau hauv 2015, tag nrho tawm ntawm LCD TV yog 215 lab units, nrog rau ib xyoo ib zaug ntawm 0.6%. Tom qab 2013, lub xyoo LCD TV xa rov qab poob dua. Nyob rau hauv 2016, tus Fed tshaj tawm tias feem cuam ntawm nce paj nqi rau cov cuab yeej cuab tam yooj yim yuav nthuav tawm, uas cuam tshuam rau lub hwj chim yuav, uas yuav ncaj qha mus rau 2016 TV khoom. Ntawm qhov kev sib tw, cov kev lag luam tseem ceeb yuav pab tau tag nrho cov kev lag luam, xws li hom lag luam yuav ua rau cov nqi ntawm cov nqi muag tag nrho, yuav tsum tau tsav tsheb tshiab ntawm kev muag khoom hauv lub caij nyoog; thiab qhov loj dua ntawm tus nqi TV yog nrov dua, pab me me kev txhim kho me me ntxiv rau loj loj. LCD TV khoom lag luam yuav tsum yog 222 lab chav nyob rau hauv 2016, nce ntawm 3.3%.

Nyob rau lub sij hawm ntev, txoj kev ua lag luam ntawm kev lag luam hloov tsawg dua, thiab nws txoj kev ua lag luam, yav tom ntej ntawm TFT-LCD nyob rau hauv lub tsheb cov cuab yeej thiab kev ua lag luam uas yuav tsum tau siv tau. Tiam sis feem ntau hais txog, tam sim no, South Kauslim muaj LGDisplay hloov mus rau OLED, Samsung kuj nyob rau hauv quantum dots R & D integrated OLED technology tsim, TV tshiab, thiab laser TV technology yuav pom, seb nws yog TV lossis txawb, LCD tshuab, nyob qhov chaw yog compressed, tsis ci ntsa iab zeem muag.
