Method for detecting touch position of active pen and electronic terminal

Abstract

The embodiment of the invention provides an active pen touch position detection method and an electronic terminal. The method comprises the following steps: when a touch position of an active pen on a screen of the electronic terminal is detected, acquiring a downlink signal according to a sensor under the screen of the electronic terminal; once the first touch position of the active pen on the screen of the electronic terminal is detected, switching off the sensors outside a first preset area including the first touch position, wherein the sensors in the first preset area are still in the working mode, and the number of the sensors in the first preset area is smaller than that of the sensors under the screen of the electronic terminal; in this way, when the second touch position of the active pen on the screen of the electronic terminal is determined subsequently, instead, the downlink signal sent by the active pen is collected only through the sensor located in the first preset area instead of being collected through all sensors under the screen of the electronic terminal all the time, so that the detection flexibility is improved.

Description

technical field [0001] The present application relates to the technical field of terminals, and in particular to a method for detecting a touch position of an active pen and an electronic terminal. Background technique [0002] As the size of the terminal screen continues to increase, in order to make the touch more accurate, an active pen can be used to perform a touch operation on the terminal screen. Especially in some writing or drawing scenes, it can not only improve the accuracy of touch, but also make the user feel more real, just like writing or drawing on paper. [0003] When the user uses the active pen to write or draw on the terminal screen, the terminal needs to continuously detect the touch position of the active pen on the terminal screen. In the prior art, when detecting the touch position of the active pen on the terminal screen, all the sensors under the terminal screen are first activated, and each sensor collects the downlink signal sent by the active pe...

AI Technical Summary

Problems solved by technology

In the prior art, when detecting the touch position of the active pen on the terminal screen, all the sensors under the terminal screen are first activated, and each sensor collects the downlink signal sent by the active pen, and then according to the information collected by each sensor The downlink signal determines the touch position of the active pen on the terminal screen; and, when continuing to detect the touch position of the active pen on the terminal screen, each sensor is still used to collect the downlink signal sent by the active pen, and according to each The downlink signal collected by the sensor determines the touch position of the active pen on the terminal screen. The detection method is relatively fixed and the flexibility is low.
