In the first spacing D7 design of the first transparent electrode string 50, there may be different ways of the above embodiments. For example, in the case where the first interval D7 of the first transparent electrode string 50 on the first central visible region is the same width, the first space between the first transparent electrode series R1 and R2 The first interval D7 between the partition D7 and the first transparent electrode series R2, R3 is smaller than each first interval D7 of the first transparent electrode serial 50 on the first central visible region. The first interval D7 between the first transparent electrode series R6, R7 and the first transparent electrode series R7, R8 are equal to the first transparent electrode string on the first central visible area. Each first interval D7 of column 50. Similarly, in the second spacing D8 design of the second transparent electrode train 56, there may be different ways of the above embodiments. For example, under the premise that each second interval D8 of the second transparent electrode serial array 56 on the second central visible region is the same width, the second interval D8 and the second transparent between the second transparent electrode serials T1 and T2 The second interval D8 between the electrode serials T2 and T3 is smaller than each second interval D8 of the second transparent electrode serial array 56 on the second central visible region. The interval D8 between the second transparent electrode series T6 and T7 and the second interval D8 between the second transparent electrode series T7 and T8 are both equal to the second transparent electrode serial 56 on the second central visible area. Each second interval D8.

In summary, the present invention narrows the spacing between the electrode strings of the visible area of the edge of the panel to improve the touch performance of the edge visible area.
