Abstract

A display driving circuit, suitable for a display device, includes multiple data circuits and multiple reading circuits. Each data circuit is configured to provide multiple data signals to corresponding ones of data lines of the display device. Each reading circuit is configured to compare multiple sensing signals on corresponding ones of sensing lines of the display device to generate a sensing result, and is configured generate multiple coupling signals according to the multiple data signals of a corresponding one of the multiple data circuits, respectively. The reading circuit is further configured to provide the multiple coupling signals to the corresponding ones of the multiple sensing lines. When the multiple data signals have one or more rising edges, the multiple coupling signals have one or more positive pulses. When the multiple data signals have one or more falling edges, the multiple coupling signals have one or more negative pulses.
