An exemplary method for determining a position of a touch event on a touch panel includes at least the following steps: scanning the touch panel by utilizing a first touch event detection threshold, and accordingly obtaining touch signal information corresponding to the touch event on the touch panel; determining if the touch panel is in a specific touch mode according to the touch signal information; and when it is determined that the touch panel is in the specific touch mode, setting a second touch event detection threshold that is different from the first touch event detection threshold, and scanning the touch panel by utilizing the second touch event detection threshold to obtain the position of the touch event.

Method for determining position of touch event on touch panel by dynamically adjusting threshold and related computer readable medium

A method for detecting noise of a touch panel and performing signal control is provided, where the method may determine how many cycles of frame data are influenced by noise, may determine whether the frame data is influenced by noise by determining whether a number of cycles influenced by noise is greater than a first threshold value or not, and may determine whether a number of continuous frame data determined to be influenced by noise is greater than a second threshold value to generate a determination result. Finally, the method may determine whether to adjust a frequency of the transmitting signals according to the determination result.
