Technical Q&A 1000 a ni.
Q: Multi-touch tih theihna tur capacitive touch screen principle chu eng nge ni?
A: Kut zungtang hian capacitive screen a khawih chuan touch point bula electrode pahnih inkara coupling a nghawng a, chu chuan electrode pahnih inkar capacitance a thlak danglam a ni. Mutual capacitance an hmuh chuan lateral electrode te chuan sequentially emit excitation pulse signals an tichhuak a, longitudinal electrode zawng zawng chuan a rualin signal an dawng vek a, chutiang chuan lateral leh longitudinal electrodes inkar zawng zawng capacitance value te chu an hmu thei a, chu chu pahnih - touch screen pumpui capacitance a ni. Touch screen-a -dimensional capacitance change data pahnih atanga a lan dan chuan touch point tinte coordinate chu chhut theih a ni. Chu chu, multi-point coordinate tak tak chu multi-Touch realise turin chhut theih a ni;
Q: Tuna kan hman mek capacitive screen chungchang hi power supply interference problem hi a nasa hle a. Power supply inrawlhna tihbo nan eng nge kan tih ang?
Scanning frequency tih loh chu power supply-a noise frequency awm loh nan signal-to-Noise ratio of the screen? A dang a awm em?A: Tuna case zawng zawng atanga hmuh chuan power supply interference hi large-size TP (7inch emaw a chunglam) ah a innghat ber a, a hnuaia solution te hi kan nei a ni:(1) Quality power supply thlang rawh. Hei hi a pawimawh hle a, power disturbances chinfelna kawng tha ber leh bulpui ber a ni a;(2) frequency hopping. Spectrum Analyzer hmangin adapter-a common mode interference strength a tlemna hmun zawng la, chutah chuan TX scan frequency chu software setting hmangin he area-ah hian set la, chu chuan interference chu a control thei ang. Full frequency band-a interference a awm chuan adapter chu kalsan a tha a;(3) Signal to noise ratio siam that. TP design hmasa berah (7.0inch emaw a chunglam) ah chuan RX signal channel atana low-impedance surface-rent material hman leh double-sided trace design hman dan tur ngaihtuah rawh. 10K chhunga channel resistance zawng zawng control tum la, chu chuan power supply interference chu a control thei ang. ;(4) Charger pawh thlak theih a ni a, algorithm filtering tihpun a ni a, anti-interference performance chak tak nei cypress, eeti, ILI scheme te pawh hman theih a ni bawk.
