Abstract

A display device includes a display controller and a timing controller to drive frames at a frame rate onto a display. The display device may include sensor circuitry to detect a signal from a pen. The signal from the pen includes a sync signal indicative of a repetition rate of the signal. In one embodiment, the sync signal and the display timer are asynchronous. The sensor circuitry is configured to sense the signal from the pen during sensing windows, where timing of the sensing windows is based on the repetition rate. In one embodiment, the display controller is configured to pause driving a frame onto the display during the sensing windows.
