Analog 8-wire resistive technology

Analog 8-wire resistive thev naus laus zis tau tsim los ua ib qho kev tshaj tawm ntawm 4-wire resistive technology, tab sis cov thev naus laus zis zoo ib yam rau 4-hlau.

8-wire resistive touch screen qauv

8-wire resistive touch screen qauv tsuas yog tib yam li cov analog 4-wire resistive touch thev naus laus zis nrog ob daim ntawv pob tshab uas sib ntsib. Ib daim ntawv muaj electrodes ntawm sab xis thiab sab laug, thiab lwm daim ntawv muaj electrodes nyob rau sab saum toj thiab hauv qab. Qhov hluav taws xob raug yuam rau ntawm daim ntawv nrog cov electrodes ntawm sab xis thiab sab laug, tom qab ntawd qhov taw tes kov hauv X kev taw qhia yog kuaj pom tias qhov voltage ntsuas los ntawm lwm daim ntawv. Tom qab ntawd, qhov hluav taws xob raug muab tso rau ntawm daim ntawv nrog cov electrodes nyob rau sab saum toj thiab hauv qab, tom qab ntawd qhov taw tes kov hauv Y kev taw qhia yog kuaj pom tias qhov voltage yog ntsuas los ntawm lwm daim ntawv.

Qhov txawv yog muaj cov kab txuas ntxiv txuas nrog txhua lub electrode hauv analog 8-wire resistive technology. Txhua lub electrode yog ntxiv nrog ib qho txuas ntxiv. Cov kab txuas ntxiv no ua haujlwm raws li cov khoom siv hluav taws xob ntxiv thiab ntsuas qhov hluav taws xob ntawm txhua lub electrodes, tom qab ntawd tawm tswv yim cov ntaub ntawv rau tus tswj. Cov ntsiab lus ntxiv qhov ntsuas no yog qhov tseem ceeb siv los ua kom lub zog ruaj khov thiab txo qhov drift los ntawm ib puag ncig kev hloov pauv.

Resistive thev naus laus zis yuav tsum tau ua haujlwm hu ua "calibration" ua ntej siv nws. Nws yog txoj haujlwm kom phim cov ntsiab lus kov ntawm lub vijtsam kov nrog cov ntaub ntawv ntawm tus cursor ntawm cov zaub. Calibration yog txoj haujlwm txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau nws, koj yuav tsum ua tib zoo saib nws, nws yog qhov yuav tsum tau ua tiav, Calibration) calibration yog txoj haujlwm. Analog 4-wire resistive thev naus laus zis xav tau kev ntsuas tsis yog thaum pib nkaus xwb tab sis tsis tu ncua vim tias kov cov ntsiab lus pom tau maj mam tawm ntawm qhov kev sib raug zoo vim qhov hloov pauv ntawm cov nqi tiv thaiv ntawm cov xaim thiab / lossis cov khoom txuas nrog lub sijhawm dhau los. Hauv analog 8-wire resistive thev naus laus zis, cov khoom siv hluav taws xob ntxiv ntsuas qhov hluav taws xob ntawm txhua lub electrode tau txais, thiab tawm tswv yim ntsuas qhov ntsuas rau tus maub los. Qhov hluav taws xob kuaj pom ntawm qhov kov tau hloov mus rau qhov chaw cov ntaub ntawv nyob rau hauv tus txheeb ze piv nrog cov lus tawm tswv yim voltage. Nyob rau hauv txoj kev no, qhov cuam tshuam ntawm kev hloov hluav taws xob ntawm electrodes tuaj yeem raug tshem tawm, yog li kev rov ua dua tshiab yuav tsis tas yuav tsum tau. Yog li, analog 8-wire resistive thev naus laus zis zoo dua li analog 4-wire resistive technology vim nws kho qhov kev sib raug zoo thiab txuag cov teeb meem ntawm recalibration.

Ua camparison ntawm 4-wire technology thiab 8-wire technology

Raws li nyob rau hauv 4-wire technology, qhov teeb meem loj yog tias ib qho kev sib koom tes axis siv cov ntawv sab nrauv, hloov tau yooj yim raws li qhov sib txawv voltage gradient, thaum txheej sab hauv lossis hauv qab ua raws li qhov ntsuas hluav taws xob. Qhov tsis tu ncua flexing uas tshwm sim ntawm cov ntawv npog sab nrauv hloov nws qhov kev tiv thaiv nrog kev siv, yog li degrading lub linearity thiab raug ntawm no axis.

Qhov kev thov rau 8-wire resistive kov vaj huam sib luag tau poob qis tom qab xyoo 1990. Qhov no yog vim kev tsim thiab cov ntaub ntawv ntawm cov ntxaij vab tshaus kov tau raug txhim kho, thiab tsis ntev los no 4-wire resistive kov cov ntxaij vab tshaus tuaj yeem siv tau ntev txaus yam tsis muaj kev rov ua dua hauv ntau daim ntawv thov. Txawm hais tias qhov ntxiv plaub qhov kev xav tau pab txhim kho lub zog tiv thaiv kev ya raws, lawv tsis txhim kho qhov kav ntev lossis lub neej expectancy ntawm lub vijtsam. Yog li 8-wire systems feem ntau pom nyob rau hauv qhov ntau thiab tsawg ntawm 10.4 ntiv tes lossis loj dua, qhov twg qhov drift tuaj yeem yog qhov tseem ceeb.
