In time interval Prd2 ', when Article 2 scan line 112 exports (2) scanning signal G, that is, Article 2 is scanned
When the voltage level of line 112 rises, control unit 114 receives the first data line 113, Article 3 data line 113 and Article 5
The first sensed data on data line 113.At this point, the first sensed data on the first data line 113 is the 1st row the 2nd column
The result that 111 mutual tolerance of sensing unit of sensing unit 111 and the 2nd row the 2nd column measures.The first sense on Article 3 data line 113
The result for answering 111 mutual tolerance of sensing unit for the sensing unit 111 and the 2nd row the 2nd column that data are the 3rd row the 2nd column to measure.Article 5
The first sensed data on data line 113 is that the sensing unit 111 that the sensing unit 111 that the 4th row the 2nd arranges and the 5th row the 2nd arrange is mutual
The result that capacity is surveyed.
When Article 3 scan line 112 to Article 8 scan line 112 exports (8) scanning signal G (3)~G, similarly, control
Unit 114 processed receives the sensing unit 111 on the first data line 113, Article 3 data line 113 and Article 5 data line 113
Mutual tolerance measure as a result, being not repeated here.
Then, control unit 114 is from 113 outputting data signals T (2) of Article 4 data line, control unit 114 in order from
8 scan lines 112 export scanning signal G (1)~G (8).In time interval Prd3 ' in Fig. 6, when first scan line 112
When exporting (1) scanning signal G, that is, when the voltage level rising of first scan line 112, control unit 114 receives Article 3

Radiation energy caused by unit 111.When finger is not touched on sensing unit 111, have between two sensing units 111
There is mutual tolerance capacitor.When finger touching is on sensing unit 111, electricity is generated between finger and two sensing units 111 respectively
Hold.The capacitor between capacitor, finger and two sensing units 111 on finger can change mutual between two sensing units 111
Hold capacitor.Control unit 114 can be according to the mutual tolerance capacitor having changed between two sensing units 111 or two sensing units
The knots modification of mutual tolerance capacitor judges the touching of finger between 111.
It next it will be described for touch device 10 to operate on from the method for sensing under molar formula, please referring again to Fig. 1, such as Fig. 1
Shown, in from molar formula, control unit 114 is from 113 outputting data signals D (1) of N data line~D (n), and by sweeping from M item
It retouches line 112 and exports scanning signal G (1)~G (m) in order.For by taking the kth scan line 112 in M scan line 112 as an example,
When kth scan line 112 exports scanning signal G (k), the third that control unit 114 receives each data line 113 incudes number
According to.That is, under molar formula, the first data line of each and the second data line of each all can outputting data signals,
And control unit 114 is made to receive the third sensed data on the second data line of the first data line of each and each.In reality
In business, due under molar formula, each data line 113 all can outputting data signals, therefore data line 113 actually not by
It is defined as the first data line and the second data line, it is only cooperation mutual tolerance mode that this, which is sentenced for the first data line and the second data line,
Explanation, be not in a limitative way the present embodiment.
When kth scan line 112 exports scanning signal G (k), the third sensed data on i-th the first data line is
Kth column on sensing unit 111 in, be electrically connected at i-th the first data line 111 self-capacity of sensing unit survey as a result,
That is, the result that 111 self-capacity of the i-th row kth column sensing unit is surveyed.Third sensed data on the second data line of j-th strip is kth
In sensing unit 111 on column, be electrically connected at the second data line of j-th strip 111 self-capacity of sensing unit survey as a result, that is,
The result that 111 self-capacity of jth row kth column sensing unit is surveyed.
Equally with the actual example of Fig. 4 for, please with reference to Fig. 4 and Fig. 7, Fig. 7 is according to another embodiment of the present invention
Depicted touch device is operated in from the voltage timing diagram under molar formula, as shown, working as the induction electrode of touch device 10
Layer 11 has 8 scan lines 112,5 data lines 113 and the induction arrays 115 that 8 column, 5 row is arranged in multiple sensing units 111
When, control unit 114 distinguishes outputting data signals D (1)~D (5) from each data line 113 first, then control unit 114
