Abstract
An electronic device includes a touch panel and a control module. On the display panel, m columns of sensing capacitors are disposed along a first direction and n rows of sensing capacitors are disposed along a second direction. The control module includes M column output channels, N row output channels, M column scan lines and N row scan lines. Each column scan line includes a first end coupled to a corresponding column output channel and a second end spreading into A sub scan lines which are coupled to A adjacent columns of sensing capacitors among the m columns of sensing capacitors, respectively. Each row scan line includes a first end coupled to a corresponding row output channel and a second end spreading into B sub scan lines which are coupled to B adjacent rows of sensing capacitors among the n rows of sensing capacitors, respectively.
