Abstract
Embodiments of the present disclosure include a touch detection method and a touch detection device. The touch detection method includes: performing, by a touch detector, a touch scan detection at a first detection frequency; and switching, by the touch detector to perform the touch scan detection at a second detection frequency in response to a touch point that is detected by the touch detector, wherein the second detection frequency is higher than the first detection frequency.
Claims20
A touch detection method, comprising:
- performing, by a touch detector, a touch scan detection at a first detection frequency;
- and
- switching, by the touch detector to perform the touch scan detection at a second detection frequency in response to a touch point that is detected by the touch detector, wherein the second detection frequency is higher than the first detection frequency.
A touch detection device, comprising:
- a controller configured to control a touch detector to perform a touch scan detection;
- and
- the touch detector configured to perform a touch scan detection at a first detection frequency under the control of the controller;
- and switch to perform the touch scan detection at a second detection frequency under the control of the controller in response to a touch point that is detected by the touch detector, wherein the second detection frequency is higher than the first detection frequency.
