Abstract
A touch sensitive processing method, comprising: generating modified codes of N orthogonal pseudo random number (PN) codes, each of PN code has M symbols, where M and N are positive integers larger than 1; transmitting driving signals modulated by the N modified codes via N first electrodes, respectively, and sensing via multiple second electrodes in a M symbols period to generate M one-dimensional sensing information arrays; calculating sums of corresponding elements of the M one-dimensional sensing information arrays corresponding to each of the second electrodes, respectively; determining whether each of the sums is in a range; and recording the M one-dimensional sensing information arrays and their corresponding N first electrodes and N PN codes in response to that at least one of the sums is determined out of the range.
