1, Lub hauv paus ntsiab lus: Lub kaum ntse ntse ntawm cov lwg me los txiav txim txoj kev tswj hwm ntawm txoj kev kho kho
Cov kua ua kua crystal molecules ntawm tn lcecules ntawm tn ltisted thiab teem rau ntawm 90℃lub kaum sab xis thaum tsis tswj hwm cov molecular deflection los ntawm ib daim teb av. Nws lub hauv paus ntsiab lus ua haujlwm yog raws li lub "twisted nematic thaj teb nyhuv" (tnfe), uas txhais tau tias qhov teeb meem teeb tau sib hloov. Yog tias lub teb hluav taws xob ua rau cov molecular axis sib txuas nrog cov kev taw qhia ntawm hluav taws xob teb, lub teeb yog thaiv, sib piv ib qho sib piv ntawm lub teeb thiab tsaus. Cov thev naus laus zis no muaj cov qauv yooj yim, tab sis tsuas yog txwv los ntawm kev npaj cov lwg me me. Nws qhov kev pom lub kaum ntse ntse yog nqaim, feem ntau ± 45 degree, thiab cov xim qhia yog ib leeg. Nws feem ntau yog siv rau cov xim dub thiab dawb.
STN LCD tiav cov zaub los ntawm nce lub kaum sab xis ntawm cov kua siv lead ua kua nplaum txog 180℃/ 270 degree, ua ke nrog txoj ntsiab cai ntawm Birefringence Kev cuam tshuam. Cov Tub Ntxhais Ua Haujlwm ntawm kev siv qib sib txawv thaum lub teeb sib cuam tshuam los ntawm cov duab ua kua, thiab tom qab kawg kev cuam tshuam zaj duab xis, thaum kawg ua tiav dub thiab dawb lossis xim zaub. Piv txwv li, ib yam qauv ntawm STN LCD admts ib hom daj ntsuab. Los ntawm kev kho cov tuab ntawm LCD ntawm tes thiab lub kaum sab xis ntawm tus lej xim, nws qhia txog cov cim daj dawb thaum muaj kev sib piv ntawm 10: 1.
2, Nthuav cov nyhuv: sib txawv sib tw hauv kev daws teeb meem, saib lub kaum ntse ntse ntse, thiab xim
Daws teeb meem thiab cov ntaub ntawv ceev
TN LCD tau txwv los ntawm qhov yooj yim matrix tsav tsheb, thiab nws cov kev daws teeb meem feem ntau yog qhov nyuaj, uas yog qhov nyuaj rau kev xav tau cov cuab yeej muaj kev lag luam. Los ntawm kev txhim kho cov kev npaj ntawm cov kua siv ua kua crystal molecules thiab cov stn LCD tuaj yeem ua tiav kev daws teeb meem ntawm 640 × 400 pixels lossis siab dua. Piv txwv li, tus tswj hwm kev lag luam siv cov vijtsam STN uas tuaj yeem tso nrog 8 kab los ntawm 40 kab ntawv ntawm cov cim ua ke, txhawb nqa cov menus suav thiab kev sib txuam.
Saib lub kaum sab xis
Lub nqaim saib lub kaum ntse ntse teeb meem ntawm TN LCD tshwj xeeb tshaj yog muaj feem tshwj xeeb hauv kev lag luam ib puag ncig. Hauv kev saib xyuas cov xwm txheej ntawm cov kab ntau lawm, cov neeg ua haujlwm yuav tsum tau soj ntsuam cov kev coj ua los ntawm kev sib txawv ntawm kev coj ua los ntawm ntau qhov sib txawv ntawm 50%, ua rau cov cim plooj. STN LCD nthuav tawm cov saib lub kaum sab xis rau ± 80℃rau ib tus qauv ntawm cov khoom lag luam ntawm 160
Xim ua tau
TN LCD yog qhov tseem ceeb ib tug monochrome zaub thev naus laus zis uas yuav tsum tau cov xim pseudo, tab sis cov xim gamut kev pab them nyiaj tsawg dua 30% NTSC thiab cov xim kev sib tw yog txhav. STN LCD PAFICCES 16 Theem Grayscale thiab 65536 xim los ntawm xim sib cais tsav thev naus laus zis. Piv txwv li, cov vijtsam STN tau siv nyob rau hauv cov cuab yeej kho mob tuaj yeem kho tau qhov sib txawv ntawm cov duab hauv ultrasound hauv ultrasound cov duab, pab kws kho mob hauv kev kuaj mob.
3, Kev tsav tsheb hom: Kev ua si ntawm cov lus teb zoo sib xws thiab ntau- channel kev tsav tsheb muaj peev xwm
Lub Sijhawm Teb Teb
Lub sijhawm teb ntawm TN LCD yog qhov tseem ceeb, nrog tus nqi ib txwm muaj ntawm 15 {30ms, xws li taug qab cov lus tsa suab ntawm kev siv neeg hlau. Txawm li cas los xij, hauv qis {{{- qhov chaw nyob hauv qab (hauv qab -20 degree), thiab lub sijhawm tsis sib haum tau txuas ntxiv rau ntau dua 100ms, ua rau muaj cov duab kab. Txawm hais tias STN LCD muaj lub sijhawm muaj txiaj ntsig tiag tiag, nws tuaj yeem cabr lub sij hawm teb kom tsawg dua li 50ms tsav tsheb-STN hybrid), ntsib cov kev xav tau ntawm kev tswj hwm feem ntau.
Ntau Channel Tsav Tsheb Muaj Peev Xwm
Muaj cov khoom siv feem ntau yuav tsum tau ib qho screen ib qho kev tsav tsheb ntau cov cim uas yuav tsum tau tso tawm cov tswv yim / cov lus qhia txog kob, thiab lwm yam. TN LCD tau txais ib qho yooj yim matrix tsav, thiab nws lub voj voog kev txwv tsis pub dhau ntawm 1/4 bias tsav, uas tuaj yeem tso tawm txog 4 kab ntawm cov cim. STN LCD tau ua tiav 1/320 kev tsis ncaj ncees tsav los ntawm ib tus qauv super twisted thiab ntxhab electro - optic nkhaus. Ib qho qauv ntawm cov khoom tuaj yeem pab txhawb 16 kab ntawm cov cim zaub, thiab cov tsav dav hlau yog dav, hloov rau cov chaw voltage nyob rau hauv cov chaw muaj kev lag luam.
4, Daim Ntawv Thov Raug Raug: Ntsuas Tus Nqi thiab Kev Ua Haujlwm
Muaj cov ntawv thov ntawm TN LCD
Cov khoom siv tus nqi qis: hauv cov xwm txheej uas yuav tsum muaj cov teeb meem yooj yim, tn lcd dominates vim nws cov qauv yooj yim thiab tus nqi qis. Piv txwv li, ib qho me me CNC lub tshuab siv tau siv ib qho kev ntsuas 3.5-nti kom pom cov khoom tsis muaj, uas txo tus nqi ntawm ib qho screen ntawm 40% piv rau cov tshuaj stn.
Dynamic saib xyuas cov xwm txheej: Hauv cov xim code nrhiav kom kaw cov yam ntxwv ntawm TN Screen tuaj yeem tso cov ntaub ntawv Sensor hauv lub sijhawm tiag tiag, ua kom tau ntim khoom.
Kev nthuav dav huab kev hloov kho: ib cov cuab yeej tshawb nrhiav roj kub tn, nrog ib qho kev ua haujlwm kub ntawm -40 Degree ~ {{1} degree, uas ua tau raws li cov cai ntawm cov haujlwm.
Muaj cov ntawv thov ntawm STN LCD
Cov Khoom Siv Hluav Taws Xob High: hauv cov qauv tiv thaiv lub zog ntawm lub zog saib xyuas, thiab lwm yam.
Tib neeg lub tshuab sib cuam tshuam davhlau ya nyob twg: Tus neeg - cov kab sib txuas lus (hmi
Cov Khoom Siv Kho Mob: Hauv Portable ultrasound kuaj, cov Grayscale zaub muaj peev xwm ntawm cov qauv STN tuaj yeem qhia meej cov qauv nqaij mos, pab kws kho mob hauv kev ua ntej.
