Q: Mult{0}}touch hpe lu la na matu capacitive touch screen ngu ai npawt tara gaw hpa rai ta?
A: Lata layung gaw capacitive screen hpe hkra ai shaloi, hkra ai shara makau na electrode lahkawng a lapran na coupling hpe hkra machyi shangun nna, dai hku nna electrode lahkawng a lapran na capacitance hpe galai shai kau ya ai. Mutual capacitance hpe mu tam ai shaloi, lateral electrodes ni gaw, n-gun rawng ai n-gun hpe n-gun jaw ai lam ni hpe hkrak hkrak shapraw ya ai, longitudinal electrodes ni yawng gaw aten langai hta sha signal ni hpe hkam la lu ai, dai hku nna, maga mi de hte galu kaba ai electrode ni a garan ginhka ai lam yawng a capacitance manu ni hpe lu la mai ai, ngu ai gaw, hkra ai screen ting a capacitance manu hpe lu la mai ai. Touch screen a capacitance galai shai ai lam lahkawng lahkawng hta tsun da ai hte maren, touch point langai hte langai a coordinate ni hpe sawn la mai ai. Dai gaw, teng man ai multi{5}point coordinate ni hpe multi{6}}touch hpe chye na na matu sawn la mai ai;
San: Ya anhte lang nga ai capacitive screen a lam hpe yu yang, power jaw ai lam hpe pat shingdang ai manghkang gaw grai sawng ai. Power supply a shang lawm ai lam hpe yeng seng kau na matu anhte hpa galaw ra ai kun? Scanning frequency hpe koi lu na matu scanning frequency hta lai nna, screen a signal-noise ratio hpe grau kaja hkra galaw na kun? Kaga lam ni nga ai kun?
A: Ya aten na mabyin masa yawng kaw na, wan n-gun garan ai lam hpe madung hku nna, madung hku nna, TP (7inch (sh) dai hta jan ai) hta madung tawn nna, lawu na hparan ladat ni hpe anhte hta nga ai:
(1) Quality power supply hpe lata la na. Ndai lam gaw grai ahkyak ai hte n-gun n-gun hpe hparan na matu akyu rawng dik htum ai hte npawt nhpang ladat mung rai nga ai;
(2) Frequency hopping. spectrum analysiser hpe lang nna, adapter a common mode interference n-gun kaji ai shara hpe tam nna, ndai shara de TX scan frequency hpe software setting hku nna masat da u, dai gaw shang lawm ai lam hpe hkrak hkra hkang lu ai. Hkum tsup ai frequency band hta shang lawm ai lam nga yang, adapter hpe kau da na matu hpaji jaw ai;
(3) Signal hte nsen ratio hpe grau kaja hkra galaw na. TP hpe shawng nnan galaw ai shaloi (7.0inch (sh) dai hta jan ai) hta, RX signal channel a matu npu na n-gun n-gun- kaw na npu na npu hpe jai lang nna, double-} maga de na hkrang hpe jai lang ai lam hpe jai lang na matu myit yu u. 10K kata na channel resistance yawng hpe hkang lu na matu shakut u, dai gaw power jaw ai lam hpe hkrak hkra hkang lu ai. ;t.
