CCD optical touchscreens ni gaw, ya nga ai hkra ai hpaji masa ni a shadawn sharam ai lam ni hpe tawt lai lu na matu, CCD touch technology hpe jai lang ma ai, hkrak tup ai lam, mahtai jaw ai lam a lawan ai lam, asak galu ai lam ni hpe grai shatsaw ya ai. Lahta na jut ni hta jung da ai CCD camera 2 gaw, lata layung law law a shara ni hpe hkrak chye lu ai, langai sha re ai tap, draging, manu jahpu n jaw ra ai hku shinggrup lu ai, sumla ni hpe zoom galaw lu ai, yawng gaw unit langai hta layung hte area hta madung nga ai. 3D object shamu shamawt ai lam ni hpe hkang lu ai pyaw hpa lam hpe mung jai lang ai ni gaw pyaw hpa lam hpe hkam sha lu nna, nhtoi hkra ai hku nna screen ntsa na virtual dusat ni hte matut mahkai lu ai. Digital signage hpaji masa hta ningnan hpaji gaw, hardware hte software rawt jat lam ni hpe hpawng de ai hku nna, hkrak tup ai lam ni hpe tsun dan ai lam ni hpe jaw ya ai, aten hte shara hta, customers ni hpe hkrak hkra hkra machyi shangun ai. Ga shadawn, arung arai ni a makau kaw screen ni hpe tawn da ai, lusha seng ni hta direct order galaw na matu, shing nrai, customer ni hpe ndau shabra na matu la nga ai shara ni hta tawn da ai. Dai hta n-ga, shinggan na mabyin kaba ni hte shelf ni hpe madun dan ai lam ni a matu, masha langai hkrai a mahkrum madup magam bungli ni hte shada da matut mahkai ai lam ni hpe shapraw ya ai lam ni gaw, digital masat kumla ni hta byin pru wa nga ai.
Interactive big-scale touch screen ni gaw, screen ntsa kaw na layung ni hpe rim la nna chye na na matu, computer shingran hpaji hpe jai lang nna, hkrang amyu myu hku nna pru wa ai. Specific algorithms ni gaw screen ntsa na physical coordinate ni hpe computer screen ntsa kaw na logical coordinates hte control command ni de galai shai ya nna, screen kaba ntsa hta hkra ai hte annotation bungli ni hpe galaw ya lu ai. Ndai lam gaw shingra tara hku nna shinggyim masha hte computer matut mahkai lam hpe lu la nna, kaji ai touch screen ni a pat shingdang ai lam ni kaw na lawt lu ai. Interactive content galaw ai lam hte kaba ai touch frame ni gaw shada da matut mahkai ai lam ni hpe mung lu la mai ai.
Lahta na hkra maga de jung da ai CCD camera gaw LED hku nna nhtoi hpe shapraw ya ai, dai hpe grup yin na nhtoi htoi ai strips ni hku nna madun dan nna, hkra maga de na CCD camera de shang wa ai. Dai hte maren, hkra maga de na CCD camera kaw na pru wa ai nhtoi hpe hkra maga na CCD camera de htawt sit ya ai. Dense light gaw hkra ai shara kata na network langai mi hpe hpaw ya ai, nhtoi htoi ai nhtoi htoi ai nsam ni a lapran na shara gaw 1mm hta n law ai. Point langai hpe hkra ai shaloi, dai shara kaw na pru wa ai nhtoi gaw angle langai mi byin wa nna, CCD camera lahkawng hpe ndai nhtoi htoi ai nsam ni hte matut mahkai ya ai dingyang line ni gaw angle lahkawng bai byin shangun ai. Dai lam a hkrak tup ai coordinate ni hpe controller wa ka matsing da ai majaw, hkra ai mahtai hpe lu la shangun ai.
Touchscreen ni gaw, hka lam hkawm ai jak ni hta shinggyim masha ni hte Computer matut mahkai lam a matu ahkyak ai daw langai mi rai nna, touchscreen hpe n-gun nnan langai a hkrang shapraw ra ai. Ndai touchscreen gaw, hkra ai bungli galaw ai lam a matu capacitive touch chips ni hpe lang nna, ngang grin ai lam, hkam sha lam, n-gun n rawng ai, hka n shang hkra, hka hte bungli galaw ai, hka n-gun hpe ninghkap lu ai atsam, hte electromagnetic shingjawng ai lam hpe ninghkap lu na matu, n-gun ja ai n-gun atsam ni hpe hkam sha lu na matu ra kadawn ai lam ni hpe hkan sa ra ai.
