The invention discloses a touch-control detection method and circuit, a storage medium, a processor and a terminal. The method includes the steps that under a touch control mode, by adjusting a value of a first register and a value of a second register, several signal-to-noise ratios corresponding to touch-control scanning signals are obtained; a signal-to-noise ratio to be found is selected from the signal-to-noise ratios, and a value combination of the first register and the second register is determined. By the adoption of the touch-control detection method and circuit, the storage medium, the processor and the terminal, the technical problem is solved that in a current touch-control detection process, because non-overlapping time cannot be flexibly adjusted, signal-to-noise ratios of scanning signals cannot be effectively improved.
Description
technical field [0001] The present invention relates to the field of touch detection, in particular to a touch detection method, circuit, storage medium, processor and terminal. Background technique [0002] Touch screens emerged from smartphones and quickly occupied the field of tablet computers. With the release of the Windows 8 system, touch screens are still moving towards electronic devices such as ultrabooks and all-in-one computers. At present, along with the wide application of the above-mentioned smart terminals, a large number of electronic devices use touch screen operations to replace the original physical keyboard operations, so as to improve the user's operation experience and visual experience. However, while it is convenient for users to use, the accuracy of touch detection is an unavoidable technical problem. [0003] figure 1 It is a schematic diagram of a partial circuit structure of a touch detection process adopted in the related art. like figure 1 ...
