Touchscreen rau ntsiav tshuaj yog ib qho ntawm cov khoom tseem ceeb. Koj tuaj yeem hais qhov tseem ceeb. Yog hais tias tsis yog rau nws, ces ua hauj lwm nrog cov gadget yuav ua tau siv mechanical tswj khawm.
Touchscreen rau lub ntsiav tshuaj lossis lwm yam thev naus laus zis yog kev nkag mus rau cov ntaub ntawv. Cov cuab yeej no yog ib qho screen uas teb rau kov nws. Nws yog nws uas yog lub luag hauj lwm rau muab kev tswj cov teeb liab rau lub operating system los yog daim ntawv thov ntawm lub gadget. Yog tias peb kos ib qho piv txwv, ces lub vijtsam kov yog nas thiab keyboard rau lub ntsiav tshuaj.

- Resistive. Lub touchscreen ntawm hom no yog cov pob tshab membrane nrog cov txheej txheem conductive, nyob rau hauv uas muaj ib lub iav uas muaj ib txheej zoo sib xws. Lub hauv paus ntsiab lus ntawm kev ua haujlwm ntawm cov cuab yeej no yog qhov yooj yim heev. Thaum koj nias lub stylus los yog ib tug ntiv tes ntawm lub vijtsam, daim nyias nyias thiab iav kaw ntawm ib qho taw tes, vim tias qhov voltage hloov hauv nws. Lub microprocessor ntes cov kev hloov pauv no thiab suav cov kev tswj hwm. Xws li ib qho screen kov muaj tus nqi qis. Tsis tas li nyob rau hauv nws txoj kev nyiam yog qhov ua tau ntawm cov lus teb kom kov nrog txhua yam khoom. Tab sis nws muaj lub zog tsawg thiab lub neej ua haujlwm me me, uas yog kwv yees li 35 lab clicks rau txhua qhov chaw. Thiab - tsis muaj qhov tseem ceeb - qhov tsis muaj peev xwm los siv ntau qhov kov. Tsis tas li ntawd, kev ua haujlwm ntawm cov zaub no yog nrog los ntawm ntau qhov yuam kev hauv kev ua haujlwm ntawm gestures "sliding" thiab "swiping". Cov tshuab no tsis siv dav hauv cov ntsiav tshuaj. Niaj hnub no koj tuaj yeem pom ib qho qauv ntawm cov cuab yeej nruab nrog lub vijtsam kov zoo sib xws. Piv txwv li, touchscreen rau ntsiav tshuaj "TEXET TM-7020".

touchscreen rau texet ntsiav tshuaj Capacitive. Qhov no yog qhov thib ob thev naus laus zis siv los tsim cov ntxaij vab tshaus kov. Cov ntxaij vab tshaus kov no tsuas tuaj yeem ua haujlwm nrog tus ntiv tes lossis lub ntsuas hluav taws xob. Hom touchscreen no tuaj yeem muab faib ua ob pawg: cov pa thiab qhov projected-capacitive. Hauv thawj hom khoom siv, txheej txheej conductive yog siv rau iav. Electrodes yog muab tso rau ntawm cov ces kaum ntawm cov zaub, uas siv ib tug alternating voltage rau txheej. Thaum koj kov lub vijtsam nrog koj tus ntiv tes, tam sim no leakage tshwm sim. Lub microprocessor saib xyuas cov ntsiab lus ntawm kev sib cuag. Qhov no yog ua los ntawm kev hloov cov kev nyeem ntawm cov electrodes, txij li thaum lub zog tam sim no nce ntau ntawm cov electrode ze tshaj plaws thiab qhov tsis kam txo. Tag nrho ntau kov ntawm cov ntxaij vab tshaus no yuav tsis ua haujlwm.
- Ntau tshaj thev naus laus zis yog qhov projected-capacitive. Sab hauv ntawm cov zaub nyob rau hauv cov ntaub ntawv no yog them nrog ib daim phiaj ntawm electrodes. Thaum ib tug ntawm lawv yog kov, ib tug capacitor yog tsim, raws li lub capacitance ntawm lub coordinates yog xam. Qhov nothev naus laus zis tso cai rau koj los ua kom tiav kev ua tiav multitouch. Ntawd yog, xws li cov zaub muaj peev xwm txhawb nqa 2, 5 lossis 10 ib txhij kov. Ib qho piv txwv zoo ntawm kev siv cov thev naus laus zis no yog lub touchscreen rau cov ntsiav tshuaj "EXPLAY sQuad 9.71".
Txoj Kev Mounting
Txhim kho lub vijtsam kov rau lub gadget yog ua los ntawm gluing. Lub touchscreen rau lub ntsiav tshuaj yog mounted rau ntawm cov zaub los yog ntawm rooj plaub. Hauv thawj kis, cov nplaum nplaum tuaj yeem siv tau tsuas yog nyob ib puag ncig ib puag ncig lossis hla tag nrho thaj tsam ntawm qhov screen. Nyob rau hauv rooj plaub thib ob, nws tau muab faib rau hauv lub cev qhov chaw uas lub sensor nyob rau hauv kev sib cuag.
khoom
Touchscreen rau lub ntsiav tshuaj tuaj yeem ua los ntawm iav lossis yas. Hauv thawj kis, lub vijtsam kov muaj cov yam ntxwv qis zog. Tsis tas li ntawd, thaum nws puas lawm, cov kab nrib pleb tam sim ntawd pom. Cov khoom siv ua los ntawm cov yas yog qhov ruaj khov dua. Thiab nyob rau hauv cov ntaub ntawv ntawm kev puas tsuaj, cov tsos ntawm cov kab nrib pleb yog tsis zoo li.
