The motion track measured.As shown in figure 4, the first electrode series connection ES1' in left side compares implementation with second electrode series connection ES2' representative
Example mutual-capacitive touch panel 100', right side first electrode series connection ES1 connect with second electrode ES2 represent it is above-mentioned first implementation
The mutual-capacitive touch panel 100 of example.In comparative examples, each second electrode E21', E23' and each first electrode E12', E14'
It is sequentially to be alternately arranged along line direction CD, and first electrode series connection ES1' is gone here and there by first electrode E12', E14' of same a line
Joining, second electrode series connection ES2' is connected in series by second electrode E21', E23' of same a line, and the first of the present embodiment

The second electrode group EM2 of two adjacent electrode E is connected in series.
As shown in Fig. 4 and Fig. 5 A, when touch control object TO is moved to position P2 from position P1, the mutual capacitance type of comparative examples is touched
It controls induction amount detected by panel 100' and the relationship of position is curve CV1, the mutual capacitance type touch surface of above-mentioned first embodiment
Induction amount and the relationship of position detected by plate 100 are curve CV2.Specifically, when touch control object TO is moved to from position P1
When position P2 (being namely moved to electrode strip group ELM2 from electrode strip group ELM1), in comparative examples, in addition to first electrode
Coupled capacitor between E12' and the second electrode EL2 of electrode strip group ELM2 can generate except variation, second electrode E21' with
Coupled capacitor between the second electrode EL2 of electrode strip group ELM2 can generate variation.Due to the electricity of second electrode E21' and second
The second electrode EL2 of pole E23' electrical connection and electrode strip group ELM2 are electrically connected with first electrode EL1, therefore second electrode
Coupled capacitor variation between E21' and the second electrode EL2 of electrode strip group ELM2 can be reacted in second electrode E23' and electrode
Between the first electrode EL1 of item group ELM2 coupled capacitor variation, that is, corresponding position P1 second electrode E21' with it is right
Answer the induction amount of the second electrode EL2 of the electrode strip group ELM2 of position P2 that can be incorporated to the induction amount of corresponding position P3, such as Fig. 5 A
Arrow shown in.In other words, when touch control object TO is located at position P2, the mutual-capacitive touch panel 100' of comparative examples is corresponding
The induction amount of position P3 can be compared with exact value height, so that detected position can be deviated towards position P3.Second electrode E21' and electricity
The second electrode EL2 of pole item group ELM2 generates capacity coupled mode can be for example as shown in fig. 6, namely second electrode E21'
Capacitive coupling is generated through the second electrode EL2 of connecting line segment and electrode strip group ELM2 between second electrode E23'.Such as
Shown in Fig. 7, in another comparative examples, when the second of the second electrode EL2 and electrode strip group ELM2 of electrode strip group ELM1
When being provided with floating electrode FE between electrode strip EL2, second electrode E21' can also be through floating electrode FE and electrode strip group ELM2
Second electrode EL2 generate capacitive coupling, and then increase electrode strip group ELM2 second electrode EL2 induction amount.
However, in this present embodiment, since the electrode E of the electrode E and corresponding position P2 of corresponding position P1 are to be electrically connected each other
It connects, and the electrode E of corresponding position P1 is not electrically connected with the electrode E of corresponding position P3, therefore when touch control object TO is mobile from position P1
When to position P2, the coupled capacitor variation between the second electrode EL2 of the electrode E and electrode strip group ELM2 of corresponding position P1 is not
It can react to the coupled capacitor variation between the electrode E of corresponding position P3 and the first electrode EL1 of electrode strip group ELM2, such as scheme
Induction amount shown in the arrow of 5A.Therefore, when touch control object TO is located at position P2, the electrode of the corresponding position P3 of the present embodiment
Induction amount detected by the first electrode EL1 of E and electrode strip group ELM2 not will receive the electrode E and electrode of corresponding position P1
Coupled capacitor between the second electrode EL2 of item group ELM2 changes interference, so that the mutual-capacitive touch panel institute of the present embodiment
The induction amount detected can avoid detected position and generate offset, and promote touch control object TO in position close to exact value
Set the detection accuracy of P2.
Similarly, as shown in Fig. 4 and Fig. 5 B, when touch control object TO is moved to position P4 from position P3, comparative examples it is mutual
Induction amount detected by appearance formula touch panel 100' and the relationship of position are curve CV3, the mutual capacitance type of above-mentioned first embodiment
Induction amount and the relationship of position detected by touch panel 100 are curve CV4.When touch control object TO is located at position P3, in right
According in embodiment, the coupled capacitor variation between first electrode E14' and the first electrode EL1 of electrode strip group ELM2 can react
Coupled capacitor variation between first electrode E12' and the second electrode EL2 of electrode strip group ELM2, that is, it is incorporated to correspondence
The induction amount of position P2, as shown in the arrow of Fig. 5 B.Therefore, when touch control object TO is located at position P3, comparative examples it is mutual
First electrode E12' and second electrode EL2 the induction amount detected of appearance formula touch panel 100' corresponding position P2 can be more accurate
Value is high, so that detected position can be deviated towards position P2.However, in this present embodiment, when touch control object TO is located at position P3
When, between the electrode E and the first electrode EL1 of electrode strip group ELM2 of corresponding position P4 coupled capacitor variation will not react to
Coupled capacitor variation between the second electrode EL2 of the electrode E and electrode strip group ELM2 of corresponding position P2, such as the arrow of Fig. 5 B
Shown in induction amount.Therefore, the second electrode EL2 sense detected of the electrode E of corresponding position P2 and electrode strip group ELM2
The coupled capacitor variation interference that will receive the first electrode EL1 of electrode E and electrode strip group ELM2 of corresponding position P4 should be measured not,
And then touch control object TO is promoted in the detection accuracy of position P3.
As shown in figure 8, motion track TR1 (i.e. dotted line shown in the 8th figure) represents the mutual capacitance type touch surface of comparative examples
Plate 100' is detected when the different location of Y-axis is moved linearly along X-direction in equidistant mode in touch control object TO
Motion track, the mutual-capacitive touch panel 100 that motion track TR2 (solid line i.e. shown in Fig. 8) system represents first embodiment exists
Moving rail touch control object TO detected when the different location of Y-axis is moved linearly along X-direction in equidistant mode
Mark.With each first electrode of comparative examples and each second electrode along line direction CD sequentially alternately arranged design for, when
The center line of the positional distance electrode strip group of touch control object TO is remoter, and detected position can deviate bigger on line direction CD,
Therefore when touch control object TO is moved linearly along line direction CD, the touch point sensed can be presented density and be alternately present
Situation.However, adjacent with the two of each second electrode group EM2 through the two adjacent electrode E of each first electrode group EM1 of the present embodiment
Electrode E is along the alternately arranged design of line direction CD, the position of position and practical touch control object TO on detected line direction CD
Offset will not be generated, and then can effectively promote the touch-control precision of mutual-capacitive touch panel 100, making for algorithm can be reduced whereby
With to reduce the consumption of calculation resources, and promoting the touch-control reaction time.
