1, Txuj Ci Txuj Ci: Minimalism ntawm Segment Code Screen thiab Complex Architecture ntawm Dot Matrix Screen
(1) Segmented code screen: qhov "deterministic" kom zoo dua ntawm passive tsav tsheb
Ntu code npo txais cov cwj mem ntu tso saib thev naus laus zis, uas tswj kev sib tw ntawm cov kua siv lead ua kua molecules los ntawm cov khoom siv hluav taws xob ua ntej los tsim cov cim ruaj khov lossis cov duab kos (xws li tus lej "8" thiab cov cim ntsuas kub). Nws qhov txiaj ntsig tseem ceeb nyob hauv nws cov qauv yooj yim thiab txiav txim siab tsav:
Passive matrix tsim: Txhua ntu ntu yog tswj hwm ntawm nws tus kheej, tshem tawm qhov xav tau rau kev tsav tsheb nyuaj thiab txo qhov kev pheej hmoo ntawm cov teeb liab cuam tshuam.
Tsawg zog hom: Thaum lub sij hawm zoo li qub zaub, tsuas yog lub LCD yuav tsum tau khaws cia nyob rau hauv ib tug deflected lub xeev, nrog lub hwj chim noj tsuas yog 1/3 mus rau 1/5 ntawm lub dot matrix screen.
Los tiv thaiv electromagnetic cuam tshuam: Tsis muaj siab -frequency signal kis tau tus mob, ruaj khov dua nyob rau hauv muaj zog cuam tshuam ib puag ncig xws li zaus converters thiab motors.
Cov xwm txheej: Cov kev tswj hwm ntawm lub tshuab dov hauv cov nroj tsuag steel siv ntu ntu code screen los tso saib cov txiaj ntsig siab. Nyob rau hauv ib puag ncig nrog electromagnetic cuam tshuam kev siv ntawm 20V / m, nws tau ua haujlwm tsis tu ncua rau 5 xyoos yam tsis muaj qhov txawv txav, thaum lub vijtsam dot matrix hauv tib qhov chaw yuav tsum tau hloov txhua xyoo vim muaj teeb meem cuam tshuam.
(2) Dot matrix screen: tus nqi ntawm "dynamism" hauv kev tsav tsheb
Dot matrix cov ntxaij vab tshaus tswj txhua pixel taw tes los ntawm kab thiab kab scanning, txhawb cov duab nyuaj, suav cov cim, thiab cov teebmeem zoo, tab sis lawv qhov kev ruaj ntseg yog txwv los ntawm:
Active matrix complexity: TFT-LCD dot matrix cov ntxaij vab tshaus yuav tsum nyias- zaj duab xis transistor (TFT) array tsav tsheb, nrog ib qho screen uas muaj ntau lab tus transistors, thiab tus nqi tsis ua hauj lwm nce nrog pixel ceev.
High zaus teeb liab cuam tshuam: Lub scanning zaus ntawm kab thiab kab nce mus txog qib kHz, uas yog yooj yim cuam tshuam los ntawm electromagnetic pulses generated los ntawm cov khoom xws li zaus converters thiab motors nyob rau hauv industrial cheeb tsam.
Fais fab kev hloov pauv: Thaum lub sij hawm dynamic zaub, lub zog noj ntawm lub backlight module yog 5-10 lub sij hawm ntawm lub segmented screen, thiab lub tshav kub dissipation siab yog ntau dua nyob rau hauv kub kub ib puag ncig.
Kev sib piv cov ntaub ntawv: Hauv qhov ntsuas kub ntawm qhov ntsuas kub ntawm -20℃txog 70 degree, qhov tsis ua haujlwm ntawm segmented code screen (0.3%) tau qis dua li ntawm dot matrix screen (2.1%), feem ntau yog vim qhov ceev ntawm cov khoom siv lead ua kua thiab kev ruaj ntseg ntawm kev tsav tsheb.
2, Muaj xwm txheej yuav tsum muaj: kev ruaj ntseg thawj "scenario adaptation txoj cai"
(1) 'Golden Scene' ntawm Duan Code Screen
Extreme ib puag ncig adaptability:
Kev them nyiaj yug qhov kub thiab txias: Muaj qib qib ntu code cov ntxaij vab tshaus tuaj yeem ua haujlwm ruaj khov hauv ib puag ncig xws li -40℃txog 85 degree. Piv txwv li, Arctic scientific tshawb fawb chaw nres tsheb cov cuab yeej siv segment code cov ntxaij vab tshaus los tso saib cov ntaub ntawv kub, uas tseem tuaj yeem pom meej meej ntawm rho tawm 40 degree.
Dustproof thiab Waterproof Design: IP67 tiv thaiv qib ntu ntu code screen tau siv rau hauv kev tswj vaj huam sib luag ntawm mining crushers, thiab tseem tuaj yeem tso tawm ib txwm thaum cov plua plav concentration nce mus txog 500mg / m ³.
Ntev lifespan yuav tsum:
Lub neej ntev ntawm cov ntaub ntawv siv lead ua kua ntau tshaj 100000 teev, thiab ntu ntu code screen ntsuas ntsuas ua haujlwm tsis tu ncua rau 8 xyoo hauv kev lag luam tshuaj qhia txog qhov sib piv ntawm qhov sib piv ntawm<15%.
(2) Lub 'muaj peev xwm ciam' ntawm dot matrix cov ntxaij vab tshaus
Cov kev txwv ntawm dynamic zaub:
Nyob rau hauv siab -ceev tswj kev ceev ceev scenarios (xws li neeg hlau caj npab trajectory taug qab), dot matrix cov ntxaij vab tshaus tej zaum yuav muaj ghosting vim yog refresh tus nqi txwv (feem ntau<60Hz), while segmented screens do not have this issue due to their static display characteristics.
Qhov sib npaug ntawm tus nqi thiab kev ruaj ntseg:
Cov kev daws teeb meem siab dot matrix cov ntxaij vab tshaus (xws li 320 × 240) raug nqi 3-5 zaug ntau dua li cov ntxaij vab tshaus segmented, tab sis cov neeg siv khoom lag luam muaj kev txhawj xeeb ntau dua txog MTBF (Lub Sijhawm Nruab Nrab Ntawm Qhov Tsis Ua Haujlwm). Raws li cov ntaub ntawv los ntawm ib lub tsheb ntau lawm kab, MTBF ntawm ntu ntu code cov ntxaij vab tshaus ncav cuag 80000 teev, thaum lub dot matrix cov ntxaij vab tshaus nyob rau hauv tib tus nqi ntau yog tsuas yog 30000 teev.
3, Cov xwm txheej: "Kev lag luam ua qauv qhia" ntawm kev txheeb xyuas kev ruaj ntseg
(1) Case 1: Roj Drilling Platform Display System
Ib qho ntawm ntug dej hiav txwv drilling platform siv ib ntu code screen los tso saib cov tsis xws li drilling siab thiab kev sib hloov ceev, thiab tau ua haujlwm tsis tu ncua rau 3 xyoos yam tsis muaj qhov ua txhaum ntawm ntsev tsuag corrosion thiab kev vibration (acceleration mus txog 5g) ib puag ncig. Kev ntsuas sib piv qhia tau hais tias tib lub platform lub dot matrix screen muaj 40% hloov pauv hauv ib xyoos vim tias LCD leakage los ntawm kev sib khi tsis ua haujlwm.
(2) Case 2: Lub sij hawm ntev stability ntawm ntse ntsuas
Ib pawg ntawm cov ntsuas ntsuas ntse los ntawm Xeev Grid Corporation ntawm Tuam Tshoj siv ntu ntu code cov ntxaij vab tshaus los tso saib kev siv hluav taws xob. Tom qab ua haujlwm nyob rau hauv ib puag ncig ntawm -30℃rau 70℃rau 5 xyoos, qhov pom pom tseeb degradation tus nqi tsawg dua 5%. Lub ntsuas ntsuas siv lub ntsuas dot matrix pom qhov txo qis hauv qhov ci mus rau 30% ntawm nws cov nqi pib tom qab 3 xyoos vim kev laus rov qab.
(3) Case 3: Tiv thaiv kev cuam tshuam ntawm cov khoom siv kho mob
Kev sib piv los ntawm ib lub chaw tsim tshuaj ntsuam xyuas kev kho mob qhia tau hais tias ntu ntu code npo tseem tuaj yeem tso tawm ib txwm nyob ze ntawm cov khoom siv sib nqus resonance imaging (MRI) (magnetic field zog ntawm 3T), thaum lub dot matrix screen muaj 25% qhov tshwm sim ntawm flickering vim electromagnetic cuam tshuam.
4, Technological Evolution: Qhov 'Stability Upgrade Path' ntawm Segment Code Screen
(1) Material Innovation
High contrast LCD: Siv ntsug alignment (VA) LCD thev naus laus zis, qhov sib piv ntawm cov segmented npo tau nce mus rau 2000: 1, thiab kev nyeem tau zoo dua li cov tshuaj TN dot matrix cov ntxaij vab tshaus hauv qhov chaw muaj zog.
Dav kub ntau yam polarizer: Kub kub tiv thaiv polarizer txuas rau sab sauv txwv ntawm kev ua haujlwm kub ntawm ntu ntu code npo rau 105 degree, ua tau raws li qhov xav tau ntawm cov xwm txheej huab cua xws li steelmaking furnaces.
(2) Kev tsim kho kom zoo
COG ntim tshuab: Chip On iav txheej txheem txo cov ntsiab lus txuas sab nraud thiab txhim kho kev co tsis kam los ntawm peb zaug.
Anti glare nto kev kho mob: Los ntawm kev siv AG etching txheej txheem los txo qhov kev xav, qhov pom pom tseeb nyob rau hauv lub teeb sab nraum zoov muaj zog yog txhim kho los ntawm 40%.
(3) Kev hloov kho tsav tsheb
Tsawg zog tsav tsheb IC: txais kev siv tshuab tsis tu ncua, txo kev siv hluav taws xob kom qis dua 0.01W thaum lub sij hawm zoo li qub.
Kev tiv thaiv siab siab -kev cuam tshuam kev tsim hluav taws xob: Los ntawm kev siv cov khoom siv lim dej thiab cov txheej txheem electromagnetic shielding, ntu ntu code screen tseem tuaj yeem ua haujlwm ruaj khov hauv 10V / m electromagnetic teb.
