1. A display system, comprising:
- an interface coupled to a host system;
a digitizer module;
a display panel; and
a control unit, coupled to the digitizer module, the display panel and the interface, according to an image signal from the host system via the interface, driving the display panel to display a corresponding image and generating a scan timing signal to the digitizer module;
wherein the digitizer module is coupled to the host system via the interface and executes a scan operation to generate position data in response to the scan timing signal,wherein the image signal comprises image data and a clock signal, wherein the control unit comprises a frequency divider performing frequency division to the clock signal of the image signal to generate the scan timing signal, wherein the digitizer module comprises sensor array, which is scanned in accordance with the scan timing signal to determine the position data.

Abstract
Display systems with digitizers. In a display system, an interface is coupled to a host system, and a control unit is coupled to a digitizer module, the display panel and the interface. The control unit drives the display panel to display a corresponding image and generates a scan timing signal to the digitizer module, according to an image signal from the host system via the interface. The digitizer module is coupled to the host system via the same interface and executes a scan operation to generate position data in response to the scan timing signal.
