Problems solved by technology
[0002] For common touch devices such as smart phones or tablet computers, the execution efficiency and detection accuracy of the device are often affected by external noise interference during operation, and false alarms may even occur when noise is mistaken for touch points point situation
And this situation will increase the extra power consumption of the touch device and wrongly execute the touch action that the user has not performed

Embodiment Construction
[0017] figure 1 is a schematic composition diagram of a touch device according to the present invention. The touch control device of the present invention includes: a touch control module 10 , a scanning frequency switching module 20 , a processing module 30 , and an alarm point storage module 40 . The touch module 10 is used to detect the user's touch signal S TOUCH , which can detect various touch operations of the user, such as clicking, sliding, continuous clicking, etc. The scanning frequency switching module 20 is used to switch the scanning frequency used for scanning the touch panel, and the switching frequency will have multiple f 1st , f 2nd ,...,f Nth , and these frequencies can be, for example, 1 kHz, 250 kHz, 1000 kHz, etc. covering a range of several kHz to thousands of kHz. The processing module 30 is used to obtain the reporting point coordinates of the touch detection module 10 , instruct the scanning frequency switching module 20 to perform frequency swi...

The invention relates to a touch control device and a detection method for touch control information. The touch control device comprises a touch control detection module, a scanning frequency switching module, a processing module and a report point storage module, wherein the touch control detection module is used for detecting report points generated by touch control or noise; the scanning frequency switching module is used for switching a plurality of scanning frequencies to the touch control detection module; the processing module is used for acquiring all the report point information under the scanning frequencies; the report point storage module is used for storing the report point information transferred from the processing module; the processing module regards the report points which are scanned out under frequencies out of the scanning frequencies as noise jamming report points; the report point storage module is not allowed to send the noise jamming report point information to an external system. The touch control device and the detection method for the touch control information has the advantages that the touch control device and the detection method can improve accuracy of the device on judging a touch control action, promote power saving efficiency and improve convenience of application.
Description
technical field [0001] The invention relates to a touch device and a touch information detection method, and in particular to a touch device and a touch information detection method capable of avoiding noise interference. Background technique [0002] For common touch devices such as smart phones or tablet computers, the execution efficiency and detection accuracy of the device are often affected by external noise interference during operation, and false alarms may even occur when noise is mistaken for touch points point situation. And this situation will increase the extra power consumption of the touch device and wrongly execute the touch action not performed by the user. Contents of the invention [0003] In view of the above problems, the present invention proposes a touch device and a touch information detection method, which can increase the accuracy of device judgment, improve power saving efficiency, and increase the convenience of use. [0004] The present inven...
