Touch sensitive controlling method, touch sensitive processing system and electronic device
The present invention provides a touch sensitive controlling method comprising continuously driving electrode(s) of a touch sensitive screen three times, wherein the two cease-driving durations between the three drivings are different.
1. A touch sensitive processing device configured to connect with a touch sensitive screen including multiple first electrodes being parallel to each other and multiple second electrodes being parallel to each other, wherein both of the first and the second electrodes form multiple intersectional points, the touch sensitive processing device comprising:
at least one driving circuit, configured to connect with at least one of the first electrodes of the touch sensitive screen; and
a processor, configured to connect with the driving circuit; to command the driving circuit to continuously drive at least one of the first electrodes of the touch sensitive screen three times; and to detect changes in capacitance by the second electrodes for detecting an object, wherein two cease-driving durations between the three drivings are different.
2. The touch sensitive processing device of claim 1 , wherein the driving comprises one of followings:
driving for a whole touch sensitive screen;
driving for a mutual capacitive touch sensitive screen; and
driving for a part of a touch sensitive screen.
3. The touch sensitive processing device of claim 1 , wherein a time length of the cease-driving duration relates to at least one of followings:
a number of interrupt-calling received by the processor in the cease-driving duration;
a type of interrupt-calling received by the processor in the cease-driving duration; and
a consumption time of interrupt service routine in response to interrupt-calling received by the processor in the cease-driving duration.
4. The touch sensitive processing device of claim 1 , wherein a time length of the cease-driving duration relates to a result produced by the processor to run a random number generating function.
