Patent ID: 8451250

Claim:
A capacitive touch panel, comprising: a plurality of driving electrodes, {X n }, n=1, 2, . . . , N, spatially arranged along a row direction; a plurality of sensing electrodes, {Y m }, m=1, 2, . . . , M, spatially arranged crossing over the plurality of driving electrodes {X n } along a column direction perpendicular to the row direction, such that the plurality of driving electrodes {X n } and the plurality of sensing electrodes {Y m } define a touch sensor matrix having N rows and M columns, each of N and M being a positive integer; and a driver electrically coupled to the touch sensor matrix and configured to generate a driving signal to synchronically drive both one of the plurality of driving electrodes {X n } and (M-j) sensing electrodes of the plurality of sensing electrodes {Y m }, wherein j=1, 2, 3, . . . , or M-1, wherein j sensing electrodes are not driven by the driving signal and are adapted to transmit a sensing signal of a touch, and wherein the remaining driving electrodes of the plurality of driving electrodes {X n } are grounded.
