Abstract: A display device includes: a display panel; an input sensor on the display panel; a panel driving circuit to drive the display panel, and to output a synchronization signal; and a sensor controller to control the input sensor. The sensor controller determines a sensing mode in response to the synchronization signal, and changes the sensing mode to a second sensing mode when the synchronization signal is activated in a first sensing mode.

Abstract: A pen sensing unit and a display device are disclosed. The pen sensing unit comprises a first pen line, a pen scan line, and a pen sensor member. The first pen line extends in a first direction. The pen scan line extends in a second direction that intersects the first direction. The pen sensor member is connected to the first pen line and the pen scan line. The pen sensor member is configured to sense input from a pen. The pen sensor member comprises a pen sensor and a pen sensor circuit. The pen sensor circuit is connected to a first end of the pen sensor. The pen sensor circuit comprises a first thin film transistor.
