Abstract

The invention provides a touch-sensitive scanning detection method and a system, as well as a capacitive touch sensor, which are applicable to the field of touch sensors. The method comprises the following steps: firstly, detecting out a sensing electrode on a capacitive touch sensor unit, corresponding to a touch position; then driving a drive electrode in a cross coupling way; conducting detection scanning on the sensing electrode in a targeted way; and finally determining the touch position. Without the need of detecting the touch sensor units on a capacitive touch sensor unit matrix one by one, the detection method decreases sampling data, reduces operational workload and achieves the purposes of saving time and power.

Description

technical field [0001] The invention belongs to the field of touch sensors, and in particular relates to a touch-sensing scanning detection method, system and capacitive touch sensor. Background technique [0002] Capacitive touch sensors have been widely used in existing touch panel and touch screen technologies based on the row-column matrix principle. The capacitive touch sensor includes a capacitive touch sensor unit matrix arranged on the lower surface of the touch panel or touch screen, and electrodes and a control device connected to the capacitive touch sensor unit matrix. [0003] During the working process, the control device drives the driving electrodes of the capacitive touch sensor unit matrix, and then detects and scans the sensing electrodes of the capacitive touch sensor unit matrix to detect the feedback signal of the capacitive touch sensor unit matrix. When the capacitive touch sensor unit matrix is ​​not touched, the feedback signal is basically unchang...
