ABSTRACT:
The present invention relates to a touch sensing device. In one embodiment, the touch sensing device includes a plurality of sensor units arranged in the form of an M×N matrix having M rows and N columns. Each sensor unit has a first touch sensor, S1,1, a second touch sensor, S1,2, a third touch sensor, S2,2, and a fourth touch sensor, S2,1, arranged in the form of a 2×2 matrix, where the first touch sensor S1,1is connected to the third touch sensor S2,2, and the second touch sensor S1,2is connected to the fourth touch sensor S2,1, respectively. The touch sensing device further includes a number of control lines having M row control lines and N column control lines. Each row control line is adapted for connecting sequentially the sensor units of a corresponding row, and each column control line is adapted for connecting sequentially the sensor units of a corresponding column.
