Abstract

The invention provides a contact sampling frequency switchover method and a contact sampling frequency switchover device. The contact sampling frequency switchover method and the contact sampling frequency switchover device are specifically applied to electronic equipment with at least two operating modes. The contact sampling frequency switchover method comprises that states of current electronic equipment is detected in a first operating mode; when the states of the current electronic equipment meet frequency switchover conditions, a contact sampling frequency switchover instruction is generated; and the electronic equipment is changed to a second operating mode according to the instruction, and a first contact sampling frequency is changed to a second contact sampling frequency. According to the embodiment of the contact sampling frequency switchover method and the contact sampling frequency switchover device, the contact sampling frequency is changed according to current states of the electronic equipment, and therefore control to the contact sampling frequency is achieved. Special requirements of touching operations can be met through changing the contact sampling frequency, and meanwhile power consumption of the equipment can be controlled. The problem that power consumption of the equipment is influenced when the special requirements of the touching operations are met due to adoption of a fixed contact sampling frequency is solved.

Description

technical field [0001] The present invention relates to the field of touch technology, in particular to a contact sampling frequency switching method and device. Background technique [0002] With the development of touch technology, electronic devices with touch sensing units are widely used, such as mobile phones, tablet computers, notebooks, remote controls and so on. The user can operate the device by lightly touching or approaching the touch sensing unit with an operating body such as a finger or a touch object, and by obtaining the position information of the touch point. The working principle of the touch sensing unit is to obtain the position information of the touch point according to the detected touch signal, and perform corresponding processing according to the position information of the touch point, so as to output the corresponding display on the display device of the touch sensing unit information. [0003] The touch sampling frequency refers to the number ...
