Abstract
The disclosure provides a touch driving device and an operating method thereof. The touch driving device uses a transmitting matrix to drive multiple transmitting electrodes of a touch panel. The touch driving device includes a first driving circuit and a second driving circuit. During a same period, the first driving circuit uses a first transmitting sub-matrix of the transmitting matrix to drive a first transmitting electrode group of the transmitting electrodes, and the second driving circuit uses a second transmitting sub-matrix of the transmitting matrix to drive a second transmitting electrode group of the transmitting electrodes. The touch driving device reads a sensing result matrix corresponding to the transmitting matrix from multiple receiving electrodes of the touch panel.
