Abstract
A driver of a display panel is provided. The driver includes a plurality of sensing channels and a signal convertor. The plurality of sensing channels are configured to receive a plurality of sensing signals from the display panel via a plurality of sensing lines and output the sensing signals. The signal convertor is coupled to the sensing channels and configured to receive the sensing signals from the sensing channels. The signal convertor receives the sensing signals from the sensing channels in different sequences during different sensing periods.
