Koj cov kab ntau lawm ua haujlwm zoo. Cov neeg siv khoom txaus siab tos txais khoom xa tuaj. Tom qab ntawd koj tus neeg muag khoom LCD xa peb - lo lus email: "Panel raug txiav lawm." Cov lus ib leeg tuaj yeem ua rau rau -Daim duab poob hauv kev tsim kho dua tshiab, rov kho dua tshiab, kev xa khoom qeeb, kev nplua rau kev cog lus, thiab kev txiav txim ploj yav tom ntej.
Thaum lub sijhawm xyoo 2020-2022 thoob ntiaj teb nti thiab vaj huam sib luag tsis txaus, lub sijhawm ua haujlwm rau tus qauv 7-inch LCD panels ballooned los ntawm 8 lub lis piam mus rau 52+ lub lis piam. Ntau pua ntawm OEM cov khoom lag luam xa tawm tau ncua lossis raug tshem tawm tam sim ntawd, nrog ntau lub tuam txhab ntsib kev tsim khoom ntau lub hlis thiab kev cuam tshuam nyiaj txiag tseem ceeb.
Seb koj tab tom nrhiav ib7 nti 1024x600 LCD nporau cov cuab yeej siv kho mob, chaw nres tsheb HMI, lub tsheb tso saib, lossis cov cuab yeej nqa tau yooj yim, cov saw hlau ruaj khov tsis yog qhov zoo - rau- muaj - nws yog qhov tseem ceeb ntawm kev pheej hmoo uas cuam tshuam ncaj qha rau koj cov khoom lag luam tus nqi, lub sij hawm- rau - kev ua lag luam, kev ua raws cai, thiab cov txiaj ntsig ntev-
Tus nqi tiag tiag ntawm LCD Supply Chain Disruption
Tus nqi ncaj qha: expediting freight, spot-kev ua lag luam tus nqi premium (panels ntawm 2–3 × tus nqi ib txwm muaj thaum 2021 tsis txaus)
Cov nqi tsis ncaj: cov kab ntau lawm nres, cov neeg siv khoom nplua, cov ntawv cog lus poob
Tus nqi engineering: redesigning PCB thiab firmware rau ib tug hloov vaj huam sib luag - ib txwm 3-6 lub hlis ncua
EOL (Xaiv-ntawm-Lub Neej) ntxiab: vaj huam sib luag cov tuam txhab txiav tawm cov qauv qauv nrog tsuas yog 6-12 lub hlis 'kev ceeb toom - feem ntau luv rau me me - ntim OEMs
Tiag - piv txwv hauv ntiaj teb: yuav ua li cas 2021 TFT LCD tsis txaus cuam tshuam rau kev lag luam OEM coj lub sijhawm thoob ntiaj teb
Qhov tsis txaus ua rau muaj qhov tsis zoo nyob thoob plaws TFT LCD ecosystem, nrog cov tsav tsheb ICs, iav substrates, polarizers, thiab cov teeb pom kev zoo tag nrho cov teeb meem loj ib txhij.

Dab tsi yog qhov ruaj khov LCD Supply Chain Tiag tiag zoo li: 6 Tsis yog - Cov Teeb Meem Sib Tham
Teeb liab 1: Vaj huam sib luag kev cog lus ua haujlwm ntev - tus neeg muag khoom lav qhov tsawg kawg 5-xyoo muaj nyob ntawm qhov tshwj xeeb 7 nti 1024x600 LCD npo qauv
Teeb liab 2: Hauv - tsev tsim khoom vs tuam txhab lag luam - cov chaw tsim khoom tswj lawv tus kheej muaj vaj huam sib luag; resellers tsis
Lub Cim 3: Txoj Cai Tswj Xyuas Kev Nyab Xeeb Kev Nyab Xeeb - puas yog cov chaw tsim khoom tuav cov khoom lag luam lossis ua haujlwm nkaus xwb ntawm kev ua -rau- xaj?
Cov Teeb Meem 4: Cov khoom siv hluav taws xob sab saud - lawv puas yuav los ntawm qib -1 cov neeg tsim vaj huam sib luag (BOE, Innolux, AUO) lossis cov khw muag khoom grey?
Teeb liab 5: Hloov pauv txoj kev npaj - yog tias lub vaj huam sib luag tseem ceeb tsis muaj, puas muaj tus pin- hloov lwm txoj kev ua ntej - tsim nyog?
Teebmeem 6: Kev sib txuas lus hauv lub sijhawm ua pob tshab - lawv puas tuaj yeem qhia koj raws nraim qhov koj xaj nyob hauv lawv cov kab ntau lawm?
Cov neeg yuav khoom feem ntau yeej tsis nug rau 6 lo lus nug no ua ntej tso lawv thawj qhov kev txiav txim OEM - thiab feem ntau cov khoom lag luam muaj teeb meem tuaj yeem kwv yees tau tom qab.
Factory vs Trading Company: Yog vim li cas nws tseem ceeb tshaj tus nqi rau ntev -Lub sij hawm muab khoom OEM
Lub tuam txhab ua lag luam tiag tiag yog li cas: tus muag khoom muag uas tau muab cov khoom lag luam los ntawm ntau lub tuam txhab - tsis muaj kev tswj hwm ntau lawm
Qhov kev pheej hmoo zais cia: cov tuam txhab lag luam feem ntau tsis tuaj yeem lav lub vaj huam sib luag sib luag ntawm cov khoom siv - LED binning, backlight spec drift, kov tswj hloov pauv
Dab tsi tiag tiag 7 TFT LCD xim zaub chaw tsim khoom tuaj yeem muab tau tias lub tuam txhab lag luam tsis tuaj yeem: ECN (Engineering Change Notification), kev cai firmware xauv, vaj huam sib luag hloov kho
Yuav txheeb xyuas qhov sib txawv li cas: Hoobkas tshawb xyuas daim ntawv teev npe - cov kab ntau lawm, cov khoom siv SMT, chav kuaj kev laus, QC chaw nres tsheb
Nqe paradox: cov tuam txhab lag luam qee zaum zoo li pheej yig dua ntawm cov nqi tsev tab sis raug nqi ntau dua ntawm cov khoom lag luam

EOL Management
Dab tsi EOL (End-ntawm-Lub Neej) txhais tau tias nyob rau hauv cov khoom siv LCD: cov chaw tsim khoom tsis tsim cov qauv vaj huam sib luag tshwj xeeb
Lub sij hawm ceeb toom EOL: 6-12 lub hlis rau cov qauv vaj huam sib luag; feem ntau luv luv rau sub-5,000 units / xyoo ntim cov neeg yuav khoom
Xeem - sij hawm - yuav (LTB) lub tswv yim: yuav ua li cas xam pes tsawg panels rau Tshuag thaum EOL ceeb toom tuaj txog

Daim ntawv thov scenarios
Scenario A: Cov cuab yeej kho mob OEM - FDA- tshem tawm cov khoom khi rau ib qho tshwj xeeb 7 nti 1024x600 LCD npo - vaj huam sib luag txiav tawm ib nrab - voj voog, ua rau rov ua dua - clearance
Lub tuam txhab tau ntsib tag nrho rov qab- cov txheej txheem xa tawm raug nqi ntau dua $ 200K thiab ncua kev nkag mus rau kev lag luam los ntawm 9 lub hlis. Kev tsim nyog dual-kev muab khoom thiab sijhawm ntev- cov ntawv cog lus muab khoom tuaj yeem tiv thaiv txoj cai npau suav phem.
Scenario B: Muaj HMI chaw tsim tshuaj paus - tuam txhab lag luam hloov vaj huam sib luag yam tsis muaj ECN ceeb toom - kov calibration so ntawm 2,000 deployed units
Kev ua tsis tiav hauv teb tau ua rau raug nqi rov qab thiab kev puas tsuaj rau lub koob npe nrov. Lub Hoobkas tiag tiag nrog cov txheej txheem ECN nruj thiab kev tswj xyuas kev hloov kho yuav zam qhov no tag nrho.
Scenario C: Lub tsheb tso saib qhov kev pab cuam - vaj huam sib luag tsis txaus quab yuam 14-lub lim tiam ntau lawm - $380K hauv kev cog lus rau txim
Automotive Tier-1 cov chaw muag khoom tau raug nplua hnyav. Kev tsim nyog thaum ntxov ntawm ob qhov chaw thiab kev ruaj ntseg cov khoom lag luam yuav tau khaws cov sijhawm xa khoom.
Scenario D: Smart home device startup - neeg siv-qib 7 TFT LCD xim zaub EOL'd tom qab 18 lub hlis - tag nrho kho vajtse kho
Kev pib ua haujlwm kub hnyiab los ntawm nws cov peev nyiaj seem ntawm kev tsim kho tshiab. Xaiv cov kev lag luam- qib panels nrog 5+ xyoo kev cog lus txij thaum pib yuav ua rau cov khoom lag luam zoo dua qub.
Scenario E: Khw muag khoom kiosk fleet - batch inconsistency los ntawm trading tuam txhab ua rau pom xim tsis sib haum nyob rau hauv 500 deployed units
Cov neeg siv khoom yws txog qhov tsis sib xws ntawm cov khoom lag luam thoob plaws qhov chaw. Factory-cov khoom siv ncaj qha nrog LED binning tswj thiab spec- khov clauses ua kom pom kev sib luag ntawm txhua pawg.
Txhua qhov xwm txheej no tiv thaiv tau. Qhov kho pib nrog nug cov lus nug uas yog thiab xaiv tus khub zoo ua ntej koj tso koj thawj qhov kev txiav txim.
Yuav ua li cas los tsim ib Resilient LCD Supply Chain
Kauj ruam 1: Tsim nyog ob qhov chaw rau koj 7-nti TFT LCD npo ua ntej loj ntau lawm tso tawm
Kauj Ruam 2: Sib tham yam tsawg kawg 5- xyoo cog lus muab khoom thiab spec-freeze clause hauv koj cov nqe lus PO
Kauj Ruam 3: Thov ECN (Engineering Change Notification) daim ntawv cog lus - txhua qhov kev hloov pauv yuav tsum tau koj daim ntawv tso cai
Kauj Ruam 4: Tsim kom muaj kev nyab xeeb cov khoom lag luam qib - kev lag luam txoj cai ntawm tus ntiv tes xoo: 3-6 lub hlis ntawm kev kwv yees xav tau tuav ntawm tus neeg muag khoom lossis hauv koj lub tsev rau khoom
Kauj Ruam 5: Kev tshuaj xyuas lub Hoobkas txhua xyoo lossis cov chaw taws teeb QC tshuaj xyuas - txheeb xyuas cov khoom siv ntau lawm, kev tshuaj xyuas cov khoom tuaj, thiab kev kuaj kev laus
Kauj Ruam 6: Khaws ib qho ua ntej - tsim nyog poob - nyob rau hauv lub vaj huam sib luag hloov ntawm cov ntaub ntawv - txawm tias koj yeej tsis xav tau
