Title: TOUCH CONTROL SCANNING DRIVING METHOD FOR REDUCING POWER CONSUMPTION
Abstract:
A touch control scanning driving method, comprising the following steps: step 1, providing a touch control display panel (1); step 2, detecting and determining whether the touch control display panel is in a standby state or a normal touch-free display state, if so, executing step 3, and if not, turning to step 4 (2); step 3, carrying out sparse touch control scanning (3); and step 4, carrying out complete touch control scanning (4). According to the touch control scanning driving method, when sparse touch control scanning is carried out, a touch control scanning pulse signal is only sent to some touch control emission electrodes by means of one-time touch control scanning, thereby reducing the number of times that the signal is received and transmitted; and when a touch control display panel is in a touch state, complete touch control scanning is carried out, so that the power consumption of the touch control display panel can be reduced without affecting the normal working and the scanning precision of the touch control display panel.
