SCANNING CONTROL METHOD AND APPARATUS FOR MUTUAL CAPACITANCE TYPE CAPACITIVE SCREEN, AND MUTUAL CAPACITANCE TYPE CAPACITIVE SCREEN

摘要

The present application provides a scanning control method and apparatus for a mutual capacitance type capacitive screen, and the mutual capacitance type capacitive screen. The scanning control method comprises: determining whether a touch signal is detected in the K-th frame of scanning or not; if not, taking a plurality of driving electrodes arranged at an equal interval of N driving electrodes as electrodes to be scanned; if yes, establishing a first scanning list according to the driving electrode which detects the touch signal in the K-th frame of scanning; selecting a driving electrode from the plurality of driving electrodes arranged at an equal interval from the N driving electrodes according to the first scanning list so as to establish a second scanning list; and taking the driving electrodes in the first scanning list and the second scanning list as said electrodes. According to the present application, the scanning frame rate can be improved, and better touch precision can be achieved.
