Claim:
1. A touch panel circuit, comprising: a plurality of first scan lines; a plurality of second scan lines, wherein the first scan lines perpendicularly intersect with the second scan lines respectively; and a first scan sensing module, comprising a plurality of first scan sensing units, each of the first scan sensing units corresponding to one of the first scan lines respectively, the each of the first scan sensing units comprising: wherein either the first logic gate or the second logic gate is turned on according to a first control signal, so that the first input terminal is connected to the first output terminal and the one of the first scan lines, or the second input terminal and the one of the first scan lines are connected to the second output terminal; second scan sensing module, comprising a plurality of second scan sensing units, each of the second sensing units corresponding to one of the second scan lines respectively, each of the second scan sensing units comprising; wherein either the third logic gate or the fourth logic gate is turned on according to a second control signal, so that the third input terminal is connected to the third output terminal and the one of the second scan lines or the fourth input terminal and the one of the second scan lines are connected to the fourth output terminal; wherein the first logic gates and the fourth logic gates are turned on simultaneously according to the first control signal and the second control signal respectively, while the second logic gates and the third logic gates are turned off simultaneously according to the first control signal and the second control signal respectively, or the first logic gates and the fourth logic gates are turned off simultaneously according to the first control signal and the second control signal respectively, while the second logic gates and the third logic gates are turned on simultaneously according to the first control signal and the second control signal respectively.
