Claim:
1. A touch sensor for a display device, comprising: a plurality of first touch electrode strings arranged in parallel; each first touch electrode string comprising the same number of first touch electrodes arranged in a first direction; a first conductive bridge and a second conductive bridge connecting two adjacent first touch electrodes in the first touch electrode strings respectively; wherein the resistance of the first conductive bridge is different from the resistance of the second conductive bridge to adjust the mutual capacitance between the plurality of the first touch electrode strings such that the mutual capacitance between the plurality of the first touch electrode strings is in the same value or the difference of the mutual capacitance between the plurality of the first touch electrode strings is within a first predetermined range; the number of the first touch electrode strings is a natural number and larger then 1; and a plurality of second touch electrode strings isolated from the plurality of first touch electrode strings; each second touch electrode string comprising the same number of second touch electrodes arranged in a second direction crossing the first direction; a third conductive bridge and a fourth conductive bridge connect two adjacent second touch electrodes in the second touch electrode strings respectively; wherein mutual capacitance in the plurality of second touch electrode strings are adjusted according to the difference between a resistance of the third conductive bridge and a resistance of the fourth conductive bridge so that mutual capacitance are in the same value or the difference between the mutual capacitance is within a second predetermined range.
