Raws li qhov nruab nrab tseem ceeb rau kev nthuav qhia cov ntaub ntawv thiab kev sib cuam tshuam, hom ntawv sau ntawv tau muaj kev sib txawv tsis tu ncua nrog cov kev xav tau ntawm daim ntawv thov thiab kev nce qib thev naus laus zis. Raws li qhov sib txawv ntawm cov yam ntxwv ntawm cov khoom siv, cov qauv kev ua haujlwm, thiab kev siv cov xwm txheej, muaj ntau yam - cov txheej txheem kev faib tawm qhov ntev tuaj yeem tsim tau, muab cov qauv xaiv xaiv rau ntau qhov chaw.
Los ntawm kev xav ntawm cov ntaub ntawv thiab kev nthuav qhia, cov ntawv sau ib txwm muab faib ua ob pawg: blackboards thiab whiteboards. Blackboards siv tsaus, tawv substrates (xws li cement, ntoo, lossis hlau) thiab chalk, tso siab rau kev sib txhuam ntawm cov khoom kom tawm cov cim. Lawv tsim nyog rau kev qhia sab hauv lossis kev cob qhia cov xwm txheej nrog cov teeb pom kev zoo uas tswj tau, thiab lawv cov yam ntxwv zoo sib xws ua kom ntev - pom kev deb. Whiteboards, ntawm qhov tod tes, siv lub teeb -xim, du panels (xws li resin, ceramic, lossis enamel) thiab dej-raws li lossis roj- raws li cov cim. Kev sau ntawv yog du thiab tshem tawm cov nplooj tsis muaj qhov seem, ua kom tau raws li kev huv thiab kev ua haujlwm ntawm cov chaw ua haujlwm niaj hnub no. Lawv feem ntau pom nyob rau hauv siab - siv zaus ib puag ncig xws li chav sib tham thiab chav sib tham.
Raws li cov txheej txheem thev naus laus zis, cov ntawv sau tuaj yeem muab faib ua cov ntawv sau lub cev thiab cov ntawv sau hluav taws xob. Cov ntawv sau lub cev sau cov ntaub ntawv los ntawm kev sib cuag nrog cov neeg kho tshuab, suav nrog blackboards, whiteboards, thiab tsis ntev los no nrov variations xws li ntsuab boards (nrog qis- cov coatings reflective) thiab enamel boards (hnyav heev -resistant). Lawv qhov zoo nyob hauv tus nqi qis, kev ua haujlwm yooj yim, thiab tsis muaj zog dependence. Cov ntawv sau hluav taws xob, ntawm qhov tod tes, hloov cov ntawv sau rau hauv cov cim digital siv electromagnetic induction, siab sensing, lossis optical positioning technology. Lawv txhawb kev khaws cia, kho, thiab ntau- ntaus ntawv sib kis, thiab qee cov khoom tseem tuaj yeem txuas nrog cov projectors thiab cov khoom siv ntse los tsim cov chaw sib koom ua ke, siv dav hauv kev kawm online, chaw taws teeb ua haujlwm, thiab tsim qauv tsim.
Raws li cov kev xav tau tshwj xeeb ntawm cov xwm txheej siv sib txawv, cov ntawv sau ntawv kuj tau faib ua ntau hom tshwj xeeb. Piv txwv li, mobile sau boards yog nruab nrog casters lossis foldable stands rau qhov chaw hloov tau yooj yim; Cov ntawv sau sib nqus embed hlau nplaum hauv lub vaj huam sib luag kom nyiam cov kab kos, cov ntawv nplaum, thiab lwm yam kev pab qhia; anti- glare sau boards txo cov teeb pom kev zoo los ntawm kev kho qhov chaw microstructure, haum rau kev qhia sab nraum zoov lossis kev nthuav qhia hauv qhov chaw ci ntsa iab; thiab cov ntawv sau kho mob muaj cov tshuaj tiv thaiv kab mob ua kom zoo dua qub thiab yooj yim -- qauv tsim kom huv si kom tau raws li cov qauv kev nyiam huv hauv kev kho mob.
Hauv qab no ntau hom kev faib tawm yog qhov hloov pauv ntawm cov ntawv sau los ntawm cov cuab yeej kaw lus yooj yim mus rau qhov xwm txheej-raws li kev daws teeb meem. Cov pawg sib txawv muaj lawv tus kheej zoo hauv kev sau ntawv, kev nthuav dav thiab kev hloov pauv ib puag ncig. Cov neeg siv tuaj yeem xaiv hom tsim nyog raws li lawv qhov xav tau tiag tiag - xws li kev sib cuam tshuam hauv kev qhia scenarios, kev ua haujlwm zoo hauv chaw ua haujlwm, thiab ua haujlwm ntev hauv qhov chaw tshwj xeeb - txhawm rau ua kom muaj txiaj ntsig zoo tshaj plaws ntawm kev sau cov ntsiav tshuaj hauv cov ntaub ntawv xa mus thiab kev sib koom tes.
