Daim duab 2: Tuam Tshoj' s vaj huam sib luag lag luam qauv tsim lag luam hauv 2019 (chav tsev:%)
Ntiaj teb vaj huam sib luag hloov mus rau Tuam Tshoj, Tuam Tshoj' s LCD ntau lawm muaj peev xwm yog No. 1
Tus kws tsim cov kua siv lead ua thev naus laus zis yog Asmeskas, thiab nws yog tus neeg Nyij Pooj uas siv cov kua siv lead ua technology ntau thiab ua cov thev naus laus zis." hegemony" ntawm kev lag luam LCD tau hloov tes los ntawm Tebchaws Meskas, Nyij Pooj, Kaus Lim Qab Teb mus rau Tuam Tshoj plaub zaug hauv tsawg dua 60 xyoo.
Xyoo 1962, American Radio Corporation tau tsim thawj cov kua siv lead ua cov qauv, thiab tom qab ntawd ces siv thev naus laus zis los qhia rau Nyijpooj.

Tuam txhab uas muag nrog tus plig ntawm" LCD Craftsman" sawv cev los ntawm Sharp tau pab txhawb rau kev tshawb fawb thiab kev tsim khoom ntawm LCD thev naus laus zis.
Nyob rau lub sijhawm xyoo 1990, South Kauslim tau txais txiaj ntsig ntawm kev poob qis hauv cov kua siv lead ua kua los kom nthuav dav thiab hloov Nyiv hauv xyoo 2000s. Los ntawm 2009, domestic BOE tshaj tawm kev tsim kho ntawm 8.5 tiam kab, tsoo cov txheej txheem thev naus laus zis ntawm Nyiv, Kaus Lim Qab Teb thiab Taiwan. Tom qab, cov tuam txhab Japanese thiab Kauslim xws li Sharp, Samsung, thiab LG, ntawm kev xav tsis thoob, tau ua tiav cov phiaj xwm los tsim cov kab 8 tiam hauv Suav teb. Txij thaum ntawd los, kev lag luam LCD hauv Suav teb lag luam tau nkag hauv kaum xyoo lub sijhawm ntawm kev nthuav dav sai.
Daim duab 3: Keeb kwm luv luv ntawm kev txhim kho qhov kev lag luam vaj huam sib luag ntiaj teb
Thaum lub Cuaj Hlis 1998, Qaum Caij Caij Tsheb Caij Nplooj Ntoos Hlav tsim ib thawj cov cim vaj huam sib luag LCD pawg ntau lawm los ntawm DTI, Nyij Pooj. Vim tias tsis muaj cov thev naus laus zis loj, lub tuam txhab tsis muaj peev xwm ua kom ruaj khov kev txhim kho. Hauv xyoo 2003, qee cov lag luam Suav tau tshaj tawm LCD vaj huam sib luag ua cov kab ntau dua, tab sis cov khoom lag luam tsis tau sib tw vim yog tus nqi them ua patent. Qhov kev sim no kuj xaus rau qhov ua tsis tiav.
Raws li xyoo 2008, Tuam Tshoj' s LCD vaj huam sib luag tseem ua tiav kev siv ntshuam, thiab tseem nyob hauv Suav teb' s noj txhua xyoo ntawm cov khoom siv txawv teb, LCD vaj huam sib luag yog thib ob rau roj, hlau ore, thiab chips, thiab qeb duas plaub.
Tom qab xyoo tsis ntev los ntawm txoj kev loj hlob, kuv lub teb chaws' s vaj huam sib luag kev lag luam tau los tom qab. Hauv xyoo 2015, kuv lub teb chaws' s LCD vaj huam sib luag tsim muaj peev xwm suav tau 23% ntawm lub ntiaj teb' s tag nrho. Raws li South Kauslim cov tuam txhab tshaj tawm lawv qhov kev tshem tawm ntawm LCD thiab tom qab ntawd hloov mus rau OLED, lub ntiaj teb LCD ntau lawm muaj peev xwm tau sib sau ntxiv hauv Suav teb loj. Thaum xyoo 2020, kuv lub teb chaws' s lub peev xwm tsim LCD tau teeb tsa ua ntej hauv lub ntiaj teb, thiab lub teb chaws Suav tau tsim txog ib nrab ntawm lub ntiaj teb' s LCD vaj huam sib luag.
Daim duab 4: keeb kwm kev loj hlob ntawm Tuam Tshoj' s vaj huam sib luag kev lag luam
Tuam Tshoj' s vaj huam sib luag muaj peev xwm loj npaum li cas yog qhov txaus ntseeg
Tsis tas li ntawd, nrog kev tawm nrawm nrawm ntawm kev tsim muaj peev xwm ntawm ntau lub LCD G8.5 / G8.6 thiab G10.5 tiam kab thiab OLED G6 tiam kab, kuv lub teb chaws' s LCD thiab OLED ntau lawm muaj peev xwm loj hlob, thiab tus nqi loj hlob yog dhau los ua ntej ntawm cov vaj huam sib luag ntiaj teb kev tsim khoom lag luam. Hauv xyoo 2018, qhov kev loj hlob ntawm kuv lub teb chaws' s LCD vaj huam sib luag tsim ntau lawm txawm tias mus txog 40.5%. Xyoo 2019, kuv lub teb chaws' s LCD thiab OLED muaj peev xwm tsim tau mus txog 113.48 lab square metres thiab 2.24 lab square metres, feem, ib xyoo-xyoo ntawm 19.6% thiab 19.8%.
Daim duab 5: 2015-2019 Tuam Tshoj thiab thoob ntiaj teb LCD ntau lawm qhov hloov pauv (chav tsev: kaum txhiab square meters,%)
Daim duab 6: 2015-2019 Tuam Tshoj thiab thoob ntiaj teb OLED qhov muaj peev xwm hloov pauv tau (chav tsev: kaum txhiab square meters,%)
Kev sib kis mob tau ua rau cov nqi vaj huam sib luag nce, thiab cov tuam txhab Kauslim tau ncua lawv txoj kev tawm ntawm lub lag luam LCD
Kev tawm tsam thoob plaws ntiaj teb xyoo 2020 tau ua rau muaj kev pom zoo los ntawm kev ntsuas kev ntsuas nyob ib puag ncig thoob ntiaj teb, thiab cov qauv xws li chaw ua haujlwm chaw nyob deb thiab kev kawm paub tau ua rau cov neeg siv khoom nthwv ntawm phau ntawv siv computer davhlau ya nyob twg khoom siv, superimposed ntawm kev tsis txaus cov khoom siv sab saum toj, thiab lub vaj huam sib luag thoob ntiaj teb tau nkag mus rau qhov kev hloov tshiab ntawm tus nqi nce ntxiv thaum Lub Rau Hli 2020. lub voj voog.
Raws li WitsView' s hais tawm tam sim no, tus nqi nruab nrab ntawm 55" W (3840 x 2160) vaj huam sib luag tau nce los ntawm Asmeskas $ 103 nyob rau lub Rau Hli 2020 txog US $ 176 thaum lub Ib Hlis 2020, nce ntawm US $ 73 tsuas yog 7 lub hlis.
Vim tias tsis muaj vaj huam sib luag rau txoj kev xa xov, cov nqi muag khoom sawv ib leeg tseem tau txais kev txhawb nqa, thiab qhov puag ncig ntawm tus nqi nce ntxiv yuav tsum txuas ntxiv mus rau lub quarter thib ob ntawm 2021.
