Q: Dɛn ne nnyinasosɛm a ɛfa capacitive touch screen ho a ɛbɛma woanya multi-touch?
A: Sɛ nsateaa no ka capacitive screen no a, ɛka coupling a ɛda electrode abien no ntam a ɛbɛn touch point no, na ɛnam so sesa capacitance a ɛda electrode abien no ntam no. Sɛ wohu mutual capacitance no a, lateral electrodes no yi excitation pulse signals no nnidiso nnidiso, na longitudinal electrodes no nyinaa nya signals bere koro mu, sɛnea ɛbɛyɛ a wobetumi anya capacitance values a ɛwɔ lateral ne longitudinal electrodes no ntam nyinaa, ɛne sɛ, capacitance a ɛwɔ abien{1}}dimensal plane no nyinaa mu. Sɛnea abien-dimensional capacitance nsakrae data a ɛwɔ touch screen no kyerɛ no, wobetumi abu touch point biara coordinates ho akontaa. Ɛne sɛ, wobetumi abu multi-point coordinates ankasa no ho akontaa na ama woahu multi-touch;
Q: Ɛfa capacitive screen a yɛde redi dwuma seesei no ho no, power supply interference haw no yɛ aniberesɛm paa. Dɛn na ɛsɛ sɛ yɛyɛ na ama yɛayi anyinam ahoɔden a ɛde ba no afi hɔ? Sɛ yɛde scanning frequency to nkyɛn sɛnea ɛbɛyɛ a wobɛkwati dede frequency a ɛwɔ power supply no mu a, ma sign-to{2}}dede ratio a ɛwɔ screen no mu no nyɛ yiye? Ɔkwan foforo bi wɔ hɔ?
A: Sɛ wohu fi mprempren nsɛm nyinaa mu a, tumi a wɔde ma no ntwitwiridii no yɛ kɛse titiriw-kɛse TP (7inch anaa nea ɛboro saa), na yɛwɔ ano aduru a edidi so yi:
(1) Paw ahoɔden a ɛfata a wɔde ma. Eyi ho hia yiye na ɛyɛ ɔkwan a etu mpɔn na ɛyɛ mfitiasede sen biara a wɔfa so di tumi a ɛhaw adwene ho dwuma;
(2) mpɛn dodow a wɔde tu mmirika. Fa spectrum analyzer no hwehwɛ beae a common mode interference ahoɔden a ɛwɔ adapter no mu no sua, na afei fa TX scan frequency no si saa beae yi so denam software nhyehyɛe so, a ebetumi adi ntwitwiridii no so yiye. Sɛ ntwitwiridii wɔ frequency band a edi mũ no mu a, wɔkamfo kyerɛ sɛ wonnyae adapter no;
(3) Ma sɛnkyerɛnne ne dede ratio tu mpɔn. Wɔ TP (7.0inch anaa nea ɛboro saa) a edi kan no mu no, susuw ho sɛ wode-impedance surface-rent ade no bedi dwuma ama RX sɛnkyerɛnne kwan no na wode nhyehyɛe a ɛwɔ abien-afã trace no adi dwuma. Bɔ mmɔden sɛ wobɛhwɛ channel resistances nyinaa so wɔ 10K mu, a ebetumi adi tumi a ɛde ba no so wɔ ɔkwan a etu mpɔn so. ; ;
(4) Ɛsan nso yɛ yie sɛ wobɛsesa charger no, ama algorithm filtering no akɔ soro, na woafa Cypress, EETI, ILI nhyehyɛeɛ a ɛwɔ anti-interference adwumayɛ a ɛyɛ den.
