Capacitive screen nishada da n-gun jaw ai lam a electrode ni hpe jat nna, multi-touch hpe lu la ra ai. Tsun mayu ai gaw, screen hpe block hku garan ai. Ginra langai hte langai hta tawn da ai shada da a capacitance modules set langai hpra gaw, langai hkrai sha bungli galaw ai majaw, .capacitive screencan langai gaw shara langai hte langai a hkra ai masa ni hpe langai hkrai sha mu lu nna, galaw ngut ai hpang, hkum hkrang hpe law law lang hkam sha lu na matu sha rai nga ai.
Cacacitive technology touch panel gaw ya aten na shinggyim hkum hkrang hpe jai lang nna bungli galaw ai. Daicapacitive screengaw, n-gun mali rawng ai shingnip shingna screen re. Glass screen a kata lam hte interlayer hpe ITO layer langai hte langai shingdaw nna ka da ai. Shinggan na layer gaw 0.0015mm sha galu ai silica glass hpe makawp maga ya ai layer re. Interlayer ITO coating hpe bungli galaw ai shara hku lang nna, jut mali gaw pru wa ai. Electrode mali, ITO a kata na layer gaw bungli galaw ai makau grup yin hpe hkam la lu na matu screen layer rai nga ai.
User wa hkra ai shaloi .capacitive screen, shinggyim hkum hkrang a wan n-gun a majaw, lang ai wa a layung hte bungli galaw ai shara gaw, coupling capacitor langai byin wa ai. Bungli galaw ai shara gaw, n-gun kaba ai signal hte matut da ai majaw, lata layung gaw, n-gun kaji hpe hkap la nna, screen a jut mali kaw nna lwi pru wa ai. Theory hku yu yang, electrode mali hku nna lwi ai current gaw, layung npawt kaw nna jut mali de tsan ai hte maren sha rai nga ai. Controller gaw, current mali a shadawn shadang hpe hkrak hkrak sawn la ai hku nna, shara hpe lu la ai. 99% hkrak ai lam de du lu nna, 3ms hta n-pu na mahtai lawan ai lam nga ai.
Daidu hkra hkra aigeneral hku nna signal transmission a matu serial port hpe lang nna, PS/2 port kaw na signal hpe la nna, TPS screen gaw host power jaw ai kaw na power hpe hkrak sha hkam la ai. Indicator nhtoi n nga ai rai yang, signal hpe n lu la ai, control box ntsa na PS/2 line hpe mung daw kau ya lu ai ngu ai lachyum re. Nhtoi htoi tu nga ai raitim, n htoi tu nga ai rai yang, control box hkrat mat ai majaw, lang ai ni gaw control box hpe galai ra ai. Control box hpe galai kau ai gaw naw n mai byin ai rai yang, screen hpe grai n-gun ja hkra dip nna, grup yin na screw ni hpe loi mi hpaw ra ai, hpa majaw nga yang,hkrat aingaw laksan arung arai ni hte galaw da ai rai nna, loi loi hte n hkrat sum ai. Serial port hkrat ai (sh) n mai lang ai rai yang, driver hpe jung ai shaloi serial port hpe shi hkrai shi tam na re majaw, driver hpe n mai bang ai. Install galaw mai ai rai yang pyi, mouse n shamu ai (sh) shara n lu ai. Serial mouse hpe lang nna serial port a quality hpe jeyang ai gaw kaja dik htum re. Serial port 9 gaw shanhte a matu ladat amyu myu hpe lang mai ai. Screen hpe dip ai, shing nrai ground wire hpe atsawm n matut da ai rai yang, n mai tam mat na re. N mai dip ai shara nkau mi nga yang, shing nrai, mahtai gaw n-gun n rawng ai rai yang, ga nhpu a majaw hkra machyi chye ai, casing hpe garan kau ra ai.
