Abstract:
1. A touch recognition method, comprising: when a touch key structure is being touched or almost being touched, supplementing charges to charge accumulation regions corresponding to each key in the touch key structure until charge amounts in the charge accumulation regions corresponding to each key reach stability; calculating charge variation in each charge accumulation region when the touch key structure is being touched according to charge supplement amounts in the charge accumulation regions corresponding to each key and calculating the ratio of the charge variation to a charge balance amount in each charge accumulation region; and recognizing the key corresponding to the charge accumulation region which has the largest charge variation and the largest ratio of the charge variation to the charge balance amount as a touched key; where after the plurality of electrodes are charged, a plurality of source electric fields are generated respectively and charge accumulation regions are formed on surfaces of the plurality of electrodes; each of the source fields penetrates a portion of the insulating touch panel corresponding to each of the plurality of keys to generate polarizing electric fields which spread out from a surface of each of the plurality of keys; and the charge accumulation regions corresponding to each of the plurality of electrodes are accumulated to be charged,
