Resistive kov screen

Qhov kov screen yog ib tug ntaus ntawv rau inputting ntaub ntawv raws li lub coordinate hauv paus ntsiab lus ntawm xaav hais tias reacts mus kov. Lawv feem ntau yog ua ib tug lwm txoj rau ib tug tag nrho heap ntawm cov neeg kho tshuab cov nyees khawm, uas yog heev yooj yim, raws li nws tso cai rau koj mus muab cov zaub thiab cov tswv yim ntaus ntawv. Txhim khu kev qha lag luam los ntawm xws li ib tug system yog ntau dua vim lub fact tias muaj yog tsis muaj cov neeg kho tshuab thiab tsiv qhov chaw.

Lub earliest qauv uas kov cov ntxaij vab tshaus twb teem nyob rau hauv lub lig sixties ntawm lub xeem caug xyoo, nws yog ces ib tug paub txog Samuel Hurst paub hais tias nws tsis xav mus koom nyob rau hauv kev nyeem ntawv kilometers tapes recorders. Nyob rau hauv 1971 nws nrhiav tau lub tuam txhab Elotouch, uas tso tawm eliograf, nruab nrab yog cov thawj xam ntaus ntawv, uas muaj ib tug resistive kov screen. Tej lub sij hawm tom qab ntawd, nws lub tuam txhab merged nrog lwm hu ua Siemens, tom qab uas nws lub npe hu ua Elographics. touch panels rau daim duab hlab tau tsim los ntawm no txoj kev koom tes uas twb existed. Nyob rau hauv 1982, lub ntiaj teb no tus thawj TV twb qhia, uas muaj ib tug kov vaj huam sib luag.

Thaum lub caij, kov cov ntxaij vab tshaus tsis feem ntau yog txwv kom muab zais ob peb hom, nyob ntawm seb, nyob li cas technology zog ntawm cov sensor. Resistive kov screen yuav ua tau chetyrhprovodnym, tsib-hlau los yog vosmiprovodnym. Dhau li nws, muaj cov ntxaij vab tshaus, capacitive, kho qhov muag, matrix, lim, raws li nyob rau hauv infrared rays thiab nyob rau lub hauv paus ntawm qhov chaw acoustic tsis. Muaj ntau ntau lub teb lwm patented yees, tab sis lawv yog cov tsis raws li nrov li resistive thiab capacitive. Feem ntau ntawm lawv yog ices los yog ua hauj lwm rau ntawm ib tug heev outdated technology.

Resistive kov screen

Qhov no hom ntawm cov zaub yog tam sim no lub feem ntau nrov. Cov feem ntau yooj yim nyob rau hauv cov nqe lus ntawm kev siv nyob rau lub sij hawm ntawd yog ib tug plaub-kov screen resistive. Nws muaj xws li ib tug iav vaj huam sib luag thiab ib tug saj zawg zog yas nyias nyias los ntawm thov ib tug nyias txheej ntawm high conductivity. Qhov chaw ntawm daim nyias nyias thiab cov iav uas muaj mikroizolyatorami uas nti tawm tiv thaiv tus nto ntawm lub kev tam sim no. Nyias hlau paib yog hu ua tus electrodes yog mounted nrog cov npoo ntawm txhua txheej. Lub pem hauv ntej txheej ntawm resistive khoom cov txheej txheem ntawm horizontally thiab mas nyob rau hauv lub tsheb, uas yog tsim los rau npaum xam uas kov coordinates. Thaum ib tug resistive kov screen yog pressed, lub kaw vaj huam sib luag tshwm sim thiab cov daim nyias nyias, thiab ib tug tshwj xeeb sensor kuj yog kaw at the point of tangency, thiab yog hloov dua siab tshiab rau hauv ib lub teeb liab. Vosmiprovodnye kov ntxaij yog ntau tshaj technology. Txawm tias muaj tseeb hais tias lawv yog cov neeg yog ntau ntau, ib tug me ntsis "ceg tawv" lawv cia siab rau thiab uptime.

Tsib-hlau resistive kov screen yog considerably ntau txhim khu kev qha vim lub fact tias cov resistive txheej membrane twb hloov los ntawm ib tug conductive, tseem ua hauj lwm txawm tias thaum cov daim nyias nyias yog puas ntsoog. Lub rear qhov rais yog them nrog ib tug tshwj xeeb cov ntaub ntawv uas nrog plaub electrodes ntawm cov fab, yog tas li nyob rau nro. Lub tsib electrode davhlau ya nyob twg ua hauj lwm pab rau pem hauv ntej txheej muaj conductive zog. Thaum lub sij hawm ntawm qhov kov screen yog ib tug kev sib tsoo ntawm lub Upper thiab qis txheej, thiab lub maub los yuav tau feem ntau kaw qhov tseeb ntawm kov ub kov no, ces muaj yog ib tug kev hloov nyob rau hauv pem hauv ntej txheej. Tom qab ntawd thawj lub keeb kwm yav dhau txheej yuav av ob kab rov tav electrodes, thiab ces muaj yog lub kaw ntawm lub ntsug electrodes.

Qhov no qhia tias lub lag luam ntawm lub resistive kov screen yog ib qho, tab sis nws yuav tsum txaus rau kev nkag siab txog cov technology.
