[0119] Based on the touch sensing unit of the fourth embodiment, in a fifth exemplary embodiment of the present invention, a touch sensing array is also provided.
[0120] Compared with the touch sensing array of the second embodiment, the touch sensing array of this embodiment is different in that the arrangement of the matrix is different, wherein the first direction signal collecting circuit and the second signal collecting circuit form an acute angle distributed.
[0121] In addition, in the touch sensing array of this embodiment, the anti-interference electrodes 30 in each touch-sensing unit are electrically connected to each other. All the anti-interference electrodes 30 may be connected as a whole, or any number of them may be connected. The anti-interference electrodes 30 are connected to each other in any combination or in any manner.
[0122] In this embodiment, due to the differences in the angle of the first direction signal acquisition circuit and the second di...
