8. Hunan Yav Tom Ntej Electronics
Hunan Yav Tom Ntej yog ib lub tuam txhab thev naus laus zis tshiab tshwj xeeb hauv R&D, tsim qauv, tsim khoom thiab muag khoom ntawm cov khoom siv ua kua siv lead ua kua thiab cov khoom txhawb nqa. Nws tau cog lus tias yuav ua ib lub tuam txhab tseem ceeb hauv kev lag luam thoob ntiaj teb, muab cov neeg siv khoom nrog cov khoom siv ua kua siv lead ua kua txheem thiab kho kom haum, lub tuam txhab tshwj xeeb hauv kev tsim khoom thiab kev ua haujlwm ntawm ntau yam monochrome LCD thiab monochrome, xim LCM (suav nrog xim TFT modules) series khoom. Tam sim no cov khoom lag luam ntawm lub tuam txhab npog LCDs xws li TN, HTN, STN, FSTN, DFSTN, thiab VA, LCMs xws li COB, COG, thiab TFT, thiab ntau yam khoom siv hluav taws xob xws li TP, OLED, thiab lwm yam.
Txij li thaum xyoo 1968, cov thev naus laus zis tau txuas ntxiv mus tsim thiab tawg, thiab cov khoom siv davhlau ya nyob twg tau nkag mus rau hauv txhua yam ntawm tib neeg txoj kev tsim khoom thiab lub neej. Nrog rau kev txhim kho tas mus li ntawm thev naus laus zis, OLED thev naus laus zis tau maj mam tshwm sim hauv thaj chaw tso saib tshiab, tab sis LCD tseem yog cov thev naus laus zis tseem ceeb.
Tom qab ntau xyoo ntawm kev txhim kho, lub peev xwm tsim khoom ntawm LCD vaj huam sib luag tau raug xa mus rau kuv lub tebchaws tas li, thiab ntau lub tuam txhab tsim khoom sib tw LCD vaj huam sib luag tau tshwm sim. Tam sim no, kev lag luam zaub vaj huam sib luag tau maj mam rov zoo thiab xav tias yuav pib lub voj voog tshiab ntawm kev loj hlob.
(1) Cov thev naus laus zis tshiab hauv kev tso saib tau vam meej, thiab LCD tseem nyob hauv qhov tseem ceeb tshaj plaws
Tam sim no, LCD thiab OLED yog ob txoj kev siv thev naus laus zis dav tshaj plaws hauv kev tsim cov zaub tshiab. Ob leeg muaj lawv tus kheej cov yam ntxwv thiab qhov zoo ntawm thev naus laus zis thiab daim ntawv thov, yog li muaj kev sib tw hauv ntau qhov xwm txheej ntawm kev siv zaub. Cov diodes teeb pom kev zoo (OLEDs), tseem hu ua cov zaub hluav taws xob laser thiab cov semiconductors teeb pom kev zoo organic, tuaj yeem hloov lub zog hluav taws xob mus rau hauv lub zog teeb ntawm cov khoom siv semiconductor organic. Cov vaj huam sib luag siv cov thev naus laus zis zaub OLED tsis tas yuav siv cov modules backlight. Txawm li cas los xij, vim tsis muaj OLED cov khoom siv tseem ceeb, kev vam khom rau kev xa khoom ntawm cov khoom siv raw tseem ceeb, cov khoom lag luam qis thiab cov nqi siab, thiab lwm yam. Los ntawm qhov kev xav ntawm cov txheej txheem kev lag luam OLED thoob ntiaj teb, kev txhim kho ntawm OLED tseem nyob rau theem pib, thiab LCD tseem nyob hauv txoj haujlwm tseem ceeb.
Raws li cov ntaub ntawv ntawm Sihan Consulting, thev naus laus zis TFT-LCD yuav suav txog 71% ntawm cov thev naus laus zis tshiab hauv xyoo 2020. TFT-LCD siv cov transistor array ntawm lub iav substrate ntawm lub vaj huam sib luag siv lead ua kua kom txhua pixel ntawm LCD muaj lub qhov hloov semiconductor ywj pheej. Txhua pixel tuaj yeem tswj cov kua siv lead ua kua ntawm ob lub iav substrates los ntawm cov pulses taw tes, uas yog, kev ywj pheej, meej thiab txuas ntxiv tswj txhua pixel "taw tes-rau-taw tes" tuaj yeem ua tiav los ntawm cov qhov hloov pauv nquag. Kev tsim qauv zoo li no pab txhim kho qhov ceev teb ntawm lub vijtsam siv lead ua kua thiab tuaj yeem tswj tau qhov greyscale uas tau tso tawm, yog li ua kom cov xim duab zoo dua thiab zoo dua.
Tib lub sijhawm, LCD thev naus laus zis kuj tseem niaj hnub tsim kho, qhia txog lub zog tshiab, thiab cov thev naus laus zis tso saib ntawm qhov nkhaus tau dhau los ua ib qho ntawm cov kev tshawb pom tshiab hauv LCD thev naus laus zis. Qhov tob ntawm daim teb pom uas tsim los ntawm kev khoov ntawm lub vijtsam tso saib nkhaus ua rau daim duab qib ntau dua thiab nplua nuj, txhim kho qhov kev nkag siab ntawm kev pom, ua rau tsis meej ntawm ciam teb nruj ntawm virtual thiab kev muaj tiag, txo qhov sib txawv ntawm daim duab ntug ntawm ob sab ntawm lub vijtsam thiab lub qhov muag tib neeg, thiab tau txais daim duab sib npaug ntau dua. Txhim kho qhov pom. Ntawm lawv, LCD variable surface module technology tawg los ntawm daim ntawv ruaj khov ntawm LCD display modules hauv kev tsim khoom loj, thiab paub txog kev hloov pauv dawb ntawm LCD variable surface modules hauv curved surface display thiab direct display, tso cai rau cov neeg siv kho lawv tus kheej raws li lawv xav tau. Nias lub khawm kom hloov ntawm cov duab ncaj thiab ncaj, thiab paub txog hom screen hauv ntau qhov xwm txheej xws li chaw ua haujlwm, kev ua si, thiab kev lom zem, thiab ua tau raws li kev siv ntau qhov xwm txheej hloov pauv.
(2) Kev hloov pauv sai ntawm lub peev xwm tsim khoom ntawm LCD vaj huam sib luag mus rau Tuam Tshoj teb chaws
Tam sim no, kev lag luam LCD vaj huam sib luag feem ntau yog nyob rau hauv Nyiv, Kaus Lim Qab Teb, Taiwan, thiab Tuam Tshoj teb chaws. Tuam Tshoj teb chaws pib lig, tab sis tau tsim kho sai heev nyob rau xyoo tas los no. Xyoo 2005, Tuam Tshoj lub peev xwm tsim LCD vaj huam sib luag tsuas yog 3% ntawm lub ntiaj teb tag nrho, tab sis xyoo 2020, Tuam Tshoj lub peev xwm tsim LCD tau nce mus txog 50%.
Thaum lub sijhawm txhim kho kev lag luam LCD hauv kuv lub tebchaws, ntau lub tuam txhab tsim khoom vaj huam sib luag LCD tau tshwm sim, xws li BOE, Shenzhen Tianma, thiab China Star Optoelectronics. Cov ntaub ntawv Omdia qhia tau tias xyoo 2021, BOE yuav qeb duas thawj zaug hauv kev xa khoom thoob ntiaj teb LCD TV vaj huam sib luag nrog 62.28 lab kev xa khoom, suav txog 23.20% ntawm kev ua lag luam. Ntxiv nrog rau kev txhim kho sai ntawm cov lag luam hauv kuv lub tebchaws, nyob rau hauv keeb kwm yav dhau los ntawm kev faib ua haujlwm thoob ntiaj teb thiab kev hloov pauv thiab qhib ntawm kuv lub tebchaws, cov tuam txhab txawv teb chaws xws li South Kauslim Samsung Display thiab LG Display kuj tau nqis peev thiab tsim cov chaw tsim khoom hauv kuv lub tebchaws, uas tau muaj kev cuam tshuam zoo rau kev txhim kho kev lag luam LCD hauv kuv lub tebchaws.
(3) Lub khw muag khoom vaj huam sib luag tau khaws thiab pib lub voj voog tshiab
Raws li cov ntaub ntawv txog tus nqi vaj huam sib luag, tom qab lub Kaum Hli Ntuj xyoo 2022, qhov kev poob qis ntawm cov vaj huam sib luag tau qeeb qeeb heev, thiab tus nqi ntawm qee qhov loj me ntawm cov vaj huam sib luag tau rov qab los. Kev rov zoo txhua hli 2/3/10/13/20 duas las Asmeskas / daim, tus nqi vaj huam sib luag txuas ntxiv mus khaws, tau rov pib dua lub voj voog nce siab. Yav dhau los, vim muaj kev poob qis hauv cov khoom siv hluav taws xob, kev muab khoom ntau dhau thiab kev thov qeeb hauv kev lag luam vaj huam sib luag sib tshooj, tus nqi vaj huam sib luag txuas ntxiv mus poob qis, thiab cov neeg ua vaj huam sib luag kuj txo qis kev tsim khoom. Tom qab yuav luag ib nrab xyoo ntawm kev tshem tawm cov khoom muag, tus nqi vaj huam sib luag yuav maj mam tsis poob qis thiab ruaj khov txij thaum kawg ntawm xyoo 2022 mus txog thaum pib ntawm xyoo 2023, thiab cov khoom xa tuaj maj mam rov qab mus rau qib khoom muag ib txwm. Tam sim no, sab kev muab khoom thiab kev thov yog qhov tseem ceeb ntawm qib qis, thiab tsis muaj mob rau kev poob qis ntawm tus nqi vaj huam sib luag tag nrho, thiab lub vaj huam sib luag tau qhia txog kev rov zoo. Raws li cov ntaub ntawv los ntawm Omdia, ib lub koom haum tshawb fawb txog kev lag luam vaj huam sib luag, tom qab ntsib qhov poob qis hauv xyoo 2022, qhov loj ntawm kev lag luam vaj huam sib luag yuav coj mus rau rau xyoo sib law liag ntawm kev loj hlob, uas yuav nce ntxiv los ntawm US $ 124.2 billion hauv xyoo 2023 mus rau US $ 143.9 billion hauv xyoo 2028, nce 15.9%. Kev lag luam vaj huam sib luag yuav coj peb qhov tseem ceeb: lub voj voog rov ua dua tshiab, kev muab khoom thiab kev thov, thiab tus nqi. Hauv xyoo 2023, nws yuav pib lub voj voog tshiab ntawm kev loj hlob. Kev rov zoo ntawm kev lag luam vaj huam sib luag kuj tau tsav tsheb nthuav dav ntawm cov chaw tsim khoom vaj huam sib luag. Raws li cov ntaub ntawv ntawm Huajing Industrial Research Institute, Tuam Tshoj lub peev xwm tsim khoom vaj huam sib luag LCD yuav yog 175.99 lab square meters hauv xyoo 2020, thiab nws yuav ncav cuag 286.33 lab square meters los ntawm xyoo 2025, nce 62.70%.
