Ib, Technical txoj cai: Iterative upgrade ntawm twist lub kaum sab xis ntawm cov kua siv lead ua kua molecules
1. TN hom: Infrastructure thiab qis - tus nqi zoo
TN hom LCD npo txais 90℃twisted nematic qauv, thiab nws cov ntsiab lus tseem ceeb yog los tswj cov kev taw qhia ntawm cov kua siv lead ua kua molecules los ntawm ib qho hluav taws xob teb, ua tiav kev xaiv kis ntawm lub teeb. Thaum tsis muaj qhov hluav taws xob siv, cov kua siv lead ua kua molecules tau teem rau hauv cov duab kauv, ua rau qhov teeb meem teeb meem rau deflect 90 degrees thiab dhau los ntawm polarizer; Tom qab siv qhov hluav taws xob, cov kua siv lead ua kua molecules ua raws li cov kev taw qhia ntawm lub tshuab hluav taws xob, thiab lub teeb raug thaiv los ntawm cov polarizer, tsim qhov sib txawv ntawm lub teeb thiab tsaus. Cov qauv no ua rau muaj ob qhov tsis xws luag hauv TN cov ntxaij vab tshaus: nqaim saib lub kaum ntse ntse (feem ntau ± 50 degree) thiab qhov sib txawv tsis tshua muaj (txog 10: 1), tab sis nws cov txheej txheem tsim tau yooj yim thiab nws cov nqi zoo yog qhov tseem ceeb, ua rau nws qhov kev xaiv zoo tshaj plaws rau qis qis thaum ntxov - cov khoom siv hluav taws xob xws li lub laij lej thiab cov moos hluav taws xob.
2. STN hom: Super twisted qauv tawg los ntawm kev saib lub tog raj kheej
Hom STN txhim kho qhov pom ntawm TN cov ntxaij vab tshaus los ntawm kev ua kom lub kaum sab xis ntawm cov kua siv lead ua kua molecules rau 180-270 degrees. Nws txoj hauv kev ua haujlwm zoo ib yam li TN, tab sis cov txheej txheem molecular ntau dua ua rau muaj qhov sib txawv ntawm qhov muag pom, tsim cov xim cuam tshuam (xws li daj ntsuab lossis xiav tom qab) tom qab dhau los ntawm polarizer. Txhawm rau tshem tawm kev tawg, STN npo yuav tsum tau txais ob txheej txheej polarizer tsim, uas nthuav tawm lub kaum sab xis saib mus rau ± 70℃thiab nce qhov sib piv rau ntau dua 30: 1. Txawm li cas los xij, qhov kev xav tau ntawm kev tsav tsheb (feem ntau yog siab dua 5V) thiab lub sijhawm teb (kwv yees li 200ms) ntawm STN tau dhau los ua qhov txwv rau nws daim ntawv thov, feem ntau yog siv rau hauv cov cuab yeej siv thiab cov xov tooj ntawm tes thaum ntxov uas xav tau cov zaub zoo.
3. FSTN hom: Kev them nyiaj yug zaj duab xis thev naus laus zis ua tiav cov xim dub thiab dawb ntshiab
FSTN nthuav qhia cov yeeb yaj kiab kho qhov muag raws li STN kom ua tiav qhov tseeb xim dub thiab dawb los ntawm kev tshem tawm cov teebmeem cuam tshuam. Lub hauv paus ntawm nws cov thev naus laus zis yog nyob rau hauv cov yeeb yaj kiab retardation hauv cov polarizer, uas tuaj yeem them nyiaj rau theem sib txawv los ntawm kev sib tw ntawm cov kua siv lead ua kua molecules, ua rau cov xim tom qab hloov los ntawm daj ntsuab / xiav mus rau dub ntshiab, thiab qhov sib piv piv rau siab dua 300: 1. FSTN khaws qhov qis-cov yam ntxwv ntawm lub zog ntawm STN (kev ua haujlwm voltage tuaj yeem qis li 3.5V), thaum ua kom zoo rau kev tsav tsheb (xws li kev txhawb nqa 8/16 tus tsav tsheb), ua rau nws yog qhov kev xaiv zoo tshaj plaws rau cov khoom siv kho mob, siab -kawg cov twj paj nruag thiab lwm yam xwm txheej uas xav tau kom pom tseeb meej.
2, Kev ua haujlwm tsis zoo: Ntsuas cov duab zoo thiab lub zog siv
Parameters TN hom STN hom FSTN hom
Kev pom ntau ± 50℃± 70℃± 90 degree
Contrast ratio 10:1 30:1 300:1
Ua haujlwm voltage 3-5V 4.5-5V 3.5-5V
Lub sij hawm teb 50-100ms 150-200ms 120-180ms
Number of Drive Channels 4-8 8-16 8-16 8-16
Cov ntawv thov ib txwm muaj xws li lub laij lej, lub moos hluav taws xob, cov cuab yeej siv ua haujlwm, cov cuab yeej siv kho mob thaum ntxov, thiab cov cuab yeej siab - kawg
Kev tsom xam ntawm qhov sib txawv tseem ceeb:
Saib lub kaum sab xis thiab qhov sib piv: FSTN nce qhov sib piv mus rau 10 npaug ntawm STN los ntawm kev them nyiaj zaj duab xis, thiab lub kaum sab xis saib yog nyob ze rau qhov pom tag nrho (± 90 degree), ua tau raws li qhov yuav tsum tau nyeem nyob rau sab nraum zoov lub teeb pom kev zoo. Piv txwv li, hauv cov khoom siv kho mob xws li cov pa oxygen concentrators, FSTN cov ntxaij vab tshaus tuaj yeem ua kom pom tseeb qhov tseem ceeb xws li oxygen concentration thiab txaus tus nqi, zam kev pheej hmoo ntawm kev nyeem tsis raug.
Tsav tsheb muaj peev xwm: STN / FSTN txhawb nqa ntau-channel tsav tsheb (xws li 16 channels), uas tuaj yeem tso saib ntau cov cim lossis cov duab yooj yim, thaum TN hom feem ntau tsuas yog txhawb 4-8 channels thiab tsim nyog rau cov duab kos duab. Piv txwv li, lub laser rangefinder siv lub FSTN screen rau ib txhij tso saib ntau yam ntaub ntawv xws li nyob deb, lub kaum sab xis, roj teeb theem, thiab lwm yam.
Kev tswj hwm kev siv hluav taws xob: FSTN optimizes cov khoom siv lead ua kua thiab tsav tsheb kom txo qis kev khiav hauj lwm voltage mus rau 3.5V thaum tswj qhov zoo sib xws. Ua ke nrog Pw tsaug zog hom (xws li STOP2 hom ntawm GD32L233 MCU), nws tuaj yeem ua tiav μ A standby lub zog noj thiab txuas lub roj teeb lub neej ntawm cov khoom siv nqa tau.
3, Kev lag luam daim ntawv thov: Scenario tsav xav tau tsav kev xaiv tshuab
1. TN hom: tus nqi rhiab rau cov khoom siv hluav taws xob
TN npo tso siab rau ultra- tus nqi qis (ib nti nqi qis dua)
0.5) thiab kev tsav tsheb yooj yim tau ua lag luam ntev ntev rau lub tshuab xam zauv, hluav taws xob tswb, cov chaw taws teeb tswj, thiab lwm yam khoom siv. Piv txwv li, qee yam ntawm lub moos hluav taws xob siv lub vijtsam TN, thiab tus nqi BOM tag nrho tuaj yeem tswj tau hauv
Tsis pub dhau 2, tsis tas yuav tsum muaj cov tsav tsheb nyuaj, haum rau loj - nplai ntau lawm.
2. STN hom: Muaj kev tswj hwm thiab cov khoom siv mobile thaum ntxov
STN cov ntxaij vab tshaus tau siv dav hauv cov cuab yeej lag luam xws li hlau sib txuas tshuab thiab cov tswj kub. Lawv lub kaum sab xis pom dav txhawb kev nyeem ntawv ib txhij los ntawm ntau tus neeg, thiab lawv cov kev muaj peev xwm ntau -channel tsav tsheb tuaj yeem pom ntau yam tsis xws li qhov kub, siab, thiab ntws tus nqi. Tsis tas li ntawd, STN yog ib qho kev daws teeb meem tseem ceeb rau cov ntxaij vab tshaus xov tooj. Piv txwv li, Nokia 1110 siv lub vijtsam STN, uas tseem tuaj yeem pom meej meej nyob rau hauv tshav ntuj, tab sis lub sij hawm teb qeeb ua rau cov duab animation lag.
3. FSTN hom: siab -kawg kho mob thiab precision instruments
FSTN cov ntxaij vab tshaus tseem ceeb hauv cov khoom siv kho mob xws li cov pa oxygen concentrators thiab cov ntsuas ntshav qabzib, nrog qhov sib txawv siab kom ntseeg tau tias cov lej / cov cim tuaj yeem nyeem tau hauv qhov chaw muaj zog lossis tsis muaj teeb pom kev zoo, thiab siv hluav taws xob tsawg txuas ntxiv lub roj teeb lub neej. Piv txwv li, qee hom pa oxygen concentrator siv FSTN npo, uas tseem tuaj yeem tso tawm cov pa oxygen kom meej meej tom qab ua haujlwm tas mus li 10 teev, thiab kev siv hluav taws xob standby tsawg dua 5 μ A. Tsis tas li ntawd, FSTN kuj tau txais txiaj ntsig zoo hauv cov cuab yeej nyiaj txiag (xws li POS tshuab) thiab cov cuab yeej tsheb vim nws txoj kev ntseeg siab thiab kev ua neej ntev (10 xyoo dhau los).
