Method for detecting touch panel noise and performing signal control and associated controller
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.
