Each item driving line X1~X8 of the driving lead described in each item into the multiple driving line group G1~G4 sends original driving signal
The amplitude of U, each driving received original driving signal U of line group is identical, and the equivalent resistance of the driving lead is big
The original drive voltage signal U that driving line is applied is greater than the original that the small driving line of the equivalent resistance for driving lead is applied
Beginning drive voltage signal U.
By being grouped to driving line in the present embodiment, and different groups of driving lines are provided with the original drive of different amplitudes
Dynamic voltage is effectively outputed to respective driving main line so that each group drives line after the partial pressure of respective driving lead
Driving voltage U0 is convergent, compensates for the different location that every group of driving line is located at touch screen, due to the impedance of respective driving lead
Each group is actually applied to caused by difference drives drive the driving voltage U0 on main line to be decayed in line to some extent to ask
Topic avoids drive so that the driving main line side of the driving line of final different groups can export the driving voltage U0 being substantially the same
Dynamic decaying of the signal in transmittance process.
It should be noted that " the original driving voltage U of at least one driving line in each driving line group here
Amplitude it is identical " refer to it is each it is described driving line group at least one driving line original driving voltage U amplitude generally
It is identical.Because when including two or more driving lines in the driving line described in every group, each item in one group drives the drive of line
The impedance of dynamic lead has a little difference in acceptable degree, then when to make each driving line in the described group
When main line side U0 being driven to export identical driving voltage amplitude, then in the original driving voltage of driving lead side application
The amplitude of U just can correspondingly have a little difference in acceptable degree.These a little differences are compared with the original driving between each group
The amplitude of voltage U is very little and insignificant, therefore acceptable, has no effect on the essence of the present embodiment.
