Hom uas kov screen: resistive thiab capacitive

Tam sim no, tsis muaj ib tug yog tag kov npo, thiaj li hu ua - ib tug touchscreen. Noj ib tug saib zoo li cas lub lag luam muaj - cov uas zoo sib xws li nruab nrog ib tug kev tshuaj ntsuam peb pom cov xov tooj thiab ntse tes, laptops thiab cov ntsiav tshuaj players, cov koob yees duab thiab video koob yees duab.

Nyob rau tib lub sij hawm, muaj ntau yam tsis txawm paub txog tag nrho cov nta ntawm ntau hom ntawm kev kov cov ntxaij vab tshaus, lawv xam qhovkev zoo thiab disadvantages. Sim kom to taub txog cov teeb meem, tab sis ua ntej yuav tsum tau ib tug me me keeb kwm digression.

Ob - peb xyoo dhau los, peb muaj resistive cov ntxaij vab tshaus, thiab lawv cov khoom technology twb zoo tsim, uas tso cai rau koj los mus ua kom kev kov panels lawv tus kheej kuj pheej yig, tiam sis feem ntau screen loj yog me me nyob rau hauv kev sib piv nrog rau cov niaj hnub.

Nco ntsoov - xaiv nws tus kheej yog tsis tau, thiab tus neeg muas zaub yog txaus siab nrog dab tsi twb muaj los ntawm lub chaw tsim tshuaj paus. Siv hloov muaj npaum li cas qhov chaw nyob rau ib lub sij hawm thaum lub lag luam tau ua ntej nkag tau kua iPhone, raws li zoo li ib co lwm yam pab kiag li lawm nrog capacitive touchscreen. Nws yog ces hais tias qhov yuav tsum tau rau ib tug tag nrho cov kev nkag siab ntawm kev sib txawv ntawm ob hom uas kov cov ntxaij vab tshaus tau ua ceev, thiab nrog cheaper ntau lawm technologies yav dhau los thiab lawv tis, qhov teeb meem yog deb ntawm kaw.

Yog li ntawd, cia kev txiav txim yuav sim kom to taub - dab tsi yog lub ntsiab sib txawv ntawm cov ob technologies thiab dab tsi lawv lub ntsiab zoo thiab disadvantages.

Tus thawj txheej txheem - ib tug resistive kov ntxaij. Lawv ua hauj lwm yog, nyob rau hauv nqe lus dav dav, yuav tau piav raws li nram no: Lub saj zawg zog membrane uas yog ncaj qha thov mus rau qhov chaw ntawm lub zaub nws tus kheej. Yog, cov zaub nto yog lub electrode system. Yog txhaj rau cov kev tshuaj ntsuam nto, bred saum daim nyias nyias muab kaw ntsia hauv qab electrode, thiab ib tug tshwj xeeb hluav taws xob ntaus ntawv los ntawm tus xov tooj xa tuaj nrog electrodes txiav txim seb tus coordinates ntawm lub cheeb tsam ntawm qhov kev tshuaj ntsuam nyob qhov twg txhaj ncaj qha thiab twb tau.

Raws li yuav pom - lub hauv paus ntsiab lus ntawm cov lag luam ntawm lub resistive screen yog yooj yim thiab txiav txim seb tus yooj yim zoo ntawm cov technology nws tus kheej - mus ua hauj lwm nrog ib tug ntaus muaj ib tug resistive kov npo, nws yog ua tau raws li ib tug ntiv tes los yog tej haum khoom - mem hluav, cwj mem, stylus, lawv tus kheej kev kov vaj huam sib luag tau khiav lag luam nyob rau hauv ib tug ntau ntau yam kub raws li zoo raws li lub simplicity thiab raws li ib tug yuav tau txais - ib tug me me nqi.

Nyob rau tib lub sij hawm nws ua hauj lwm technology predetermines lub ntsiab tsis zoo ntawm tej cov ntxaij vab tshaus - ib tug tsis muaj them nyiaj yug rau multi-kov thiab me me sij hawm lub neej ntawm resistive touchscreens, piv txwv li - lawv hnav tawm sai sai. Luv neej vim lub fact tias cov ua hauj lwm ntawm resistive cov ntxaij vab tshaus yog raws li nyob rau hauv txhua yam kev sib cuag. Nyob rau hauv tas li ntawd, raws li qhov chaw ntawm qhov kev tshuaj ntsuam yog tsis siv lub khob thiab tshwj xeeb polymer zaj duab xis, uas yog them nrog khawb, nws loses nws transparency, uas yuav tsum tau siv tshwj xeeb kev tiv thaiv films txo lub qhov ci ntawm lub screen thiab cov neeg ntawm lub sensors.

Qhov thib ob technology siv los tsim qhov kov panels - capacitive cov ntxaij vab tshaus. Panels ntawm no hom yog iav screen loj nrog ib pob tshab conductive txheej saum npoo av. Thaum lub ces kaum ntawm lub screen yog cov electrodes uas siv voltage rau lub conductive txheej, thiab thaum twg ib tug ntiv tes nphav ib tug cheeb tsam ntawm qhov kev tshuaj ntsuam ntawm hluav taws xob xwb to tshwm sim vim lub fact tias cov tib neeg lub cev muaj ib tug capacitance. Tshwj xeeb hluav taws xob ntaus ntawv nyeem coordinates ntawm lub cheeb tsam ntawm qhov kev tshuaj ntsuam nyob qhov twg ib tug kev lub sij hawm ntawd paim quav hluav taws xob xwb thiab yog li ntawd - cov coordinates ntawm lub cheeb tsam nyob qhov twg kov tshwm sim ntiv tes.

Yog li, qhov kov vaj huam sib luag los ntawm kev siv capacitive technology, muaj ntau dua kev ntseeg tau thiab muaj peev xwm txhawb multi-kov technology zoo li - tsis txhob yuav tsum tau ib tug ncaj qha kais lub screen - yooj yim txaus mus kov, uas tsub kom lawv usability thiab durability. Tab sis rau capacitive cov ntxaij vab tshaus technologically predetermined tooj ntawm shortcomings - thaum tsis zoo kub raug txo los yog nres cov kev tshuaj ntsuam ntawm tag nrho cov teb cov lus rau ib tug neeg txiav txim.

Yog li ntawd, saum toj no peb tau kawm ob lub technology siv los tsim ib tug niaj hnub kov ntxaij. Yog li ntawd dab tsi li koj xaiv tus neeg siv - nrog ib tug resistive los yog capacitive kov npo ntaus ntawv? Wb sim txheeb tawm qhov teeb meem no.

Niaj hnub no, ntawm cov kws txawj, lub thoob plaws txoj kev ntseeg hais tias yav tom ntej yog rau capacitive cov ntxaij vab tshaus. Nyob rau hauv tas li ntawd, cov technology yog tsim thiab, raws li, tej shortcomings yuav tsis tshua los yog tshem tawm tag nrho ua ke. Thaum xaiv ib tug ntaus ntawv, koj yuav tsum nqa mus rau hauv tus account qhov loj ntawm lub screen - thaum ua hauj lwm nrog cov ntsiav tshuaj, smartphone los yog lwm yam kev kov screen ntaus ntawv mus ua hauj lwm tsis siv cov stylus swm.

Yog hais tias cov tswv yim yuav tsum tau xyuas kom meej tseeb, thiab kuj tsim nyog los tsim graphics, kos duab, kos duab, los ntawm kev siv qhov kov vaj huam sib luag, nws yog tsim nyog los siv ib tug capacitive kov vaj huam sib luag, tshwj xeeb active txoj hauj lwm hom. Rau resistive panels, uas yog tseem lug muaj nyob rau ntawm lub lag luam niaj hnub no, cov ntau tseem pheej yig nyiaj txiag pab kiag li lawm, tab sis lawv cov uas tsis muaj nqi yog hnub no tej zaum tsuas zoo dua.
