1967: Marvin Township kaw na Royal Radar Institute kaw na EA Johnson gaw touch screen ngu ai myit masa hpe tang madun ai wa re ngu ai hpe masha law law kam ma ai.
Industrial capacitive screen hpaji ninghkring, nambat 183, lapran na mali gaw 2005 ning rai nna, hpang jahtum mali gaw 9375 re.
1965 ning hta, computer sawk sagawn ai masha langai mi gaw, "Touch Panel: Computer Input Device" ngu ai laika man kadun hpe shapraw nna, "Electronics-Letters" ngu ai magazine hta, shi hkum shi capacitive ngu tsun da ai. Touch screen a myit masa: screen a madung hkum hkrang gaw, n-gun rawng ai glass screen, kata na ntsa hpe ITO ngu ai magri oxide layer hte ka-up da nna, jut mali hta electrode mali nga ai. Lata layung gaw glass screen hpe hkra ai shaloi, shinggyim hkum hkrang a wan n-gun a majaw, lata a n-gang hte glass a kata na layer gaw capacitance byin wa nna, dai hku nna shara kaw na current loi mi hpe "hkap la kau" ai. Ndai "leakage" current gaw electrode mali kaw na lwi pru wa nna, theoretical hku yu yang, electrode amyu myu hku nna lwi pru wa ai daw gaw, lata layung kaw nna electrode de tsan ai shara hte maren sha rai nga ai. Controller hpe hkrak hkrak sawn la ai hku nna, layung a shara hpe hkrak hkrak lu la mai ai.
Lahkawng ning na ai hpang, Johnson gaw ndai shingran hpe tengman ai lam de galai shai kau ya nna, shinggyim labau hta shawng nnan na touch screen hpe hpaw ya ai, Ergonomics ngu ai laika buk langai mi hta touch screen a sumla hte touch screen a madung schematic hpe shapraw ai. Magazine hta. Ndai gaw yak hkak ai raitim, n-gun nnan lu ai screen re. Johnson a hkrang shapraw ai hta, lamik kumla langai mi pyi nga ai: lata gara kaw madun da ai raitim, screen gaw dai kaw htoi tu na re.
2007 ning March shata hta, LG gaw Parada multi-point capacitive touch screen hpe shapraw wa ai, dai gaw touch pen n ra ai sha, grai hkrak ai.
2007 ning June shata kaw nna, Apple gaw iphone law law hpe n-gun dat ai touch screen amyu myu hpe shapraw wa sai rai nna, capacitive screen gaw lawan ai hku rawt jat wa ai.
