Patent ID: 8749503

Claim:
A touch position detector comprising: a touch panel comprising at least three groups of mutually-parallel electrodes, at least two of the at least three groups arranged at a predefined angle; a detection module operable to detect position information for each of the at least three groups, the position information corresponding to n touched positions on the touch panel, the detection module operable to detect position information x comprising a position X1 and a position X2 of a first electrode group; detect position information y comprising a position Y1 and a position Y2 of a second electrode group; detect position information z comprising a position Z1 and a position Z2 of a third electrode group; and an identification module operable to identify the n touched positions based on the position information and the predefined angle, the identification module operable to calculate a calculated position Z3 based on the position X1 and the position Y1; identify coordinates (X1, Y1), (X2, Y2) as one of the touched positions, if the calculated position Z3 is equal to at least one of the position Z1 and the position Z2; and identify coordinates (X1, Y2), (X2, Y1) as one of the touched positions, if the calculated position Z3 is not equal to at least one of the position Z1 and the position Z2.
