As kth bar scan line 112 output scanning signal G (k), control unit 114 receives the 3rd sensing number of each data line 113
According to.It is to say, under molar formula, each the first data wire and each the second data wire all can outputting data signals,
And make control unit 114 receive the 3rd sensed data on each article of the first data wire and each article of the second data wire.In reality
In business, due under molar formula, each data line 113 all can outputting data signals, therefore data wire 113 the most not by
Being defined as the first data wire and the second data wire, this is only for sentencing the first data wire and the second data wire and coordinates mutual tolerance pattern
Explanation, be not in a limitative way the present embodiment.
As kth bar scan line 112 output scanning signal G (k), the 3rd sensed data on i-th article of first data wire is
In sensing unit 111 on kth row, it is electrically connected at the result that sensing unit 111 self-capacity of i-th the first data wire is surveyed,
That is i-th row kth row sensing unit 111 self-capacity survey result.The 3rd sensed data on j-th strip the second data wire is kth
In sensing unit 111 on row, it is electrically connected at the result that sensing unit 111 self-capacity of j-th strip the second data wire is surveyed, that is
The result that jth row kth row sensing unit 111 self-capacity is surveyed.
For equally with example actual for Fig. 4, it is according to another embodiment of the present invention please with reference to Fig. 4 and Fig. 7, Fig. 7
