Display device and electronic device including the same

An electronic device comprising:

• a display panel comprising a display area at which an image is displayed;
• an input sensor on the display panel and configured to operate in a first mode to sense a first input or in a second mode to sense a second input;
• a sensor controller configured to control an operation of the input sensor;
• an input device configured to provide the second input to the input sensor;
• and
• a wireless power supply configured to transmit a wireless power signal to the input device at a transmission frequency in response to the input sensor operating in the second mode, and
• a power controller configured to receive a power control auxiliary signal from the sensor controller and to transmit a power control signal to the wireless power supply, and
• wherein the sensor controller is configured to transmit an uplink signal having a first frequency to the input device through the input sensor in the second mode, and the uplink signal comprises a set signal corresponding to the transmission frequency of the wireless power signal, and
• wherein the power control auxiliary signal comprises recognition information on a presence or absence of the input device, and
• the power controller is configured to determine whether to supply the wireless power signal based on the recognition information.

A display device comprising:

• a display panel comprising a display area at which an image is displayed;
• an input sensor on the display panel and configured to operate in a first mode to sense a first input or in a second mode to sense a second input provided by an input device;
• a sensor controller configured to control an operation of the input sensor;
• and
• a wireless power supply configured to transmit a wireless power signal to the input device in response to the input sensor operating in the second mode, wherein the sensor controller is configured to sense the first input through the input sensor during a first input sensing frame and to sense the second input through the input sensor during a second input sensing frame, the wireless power supply is configured to transmit the wireless power signal to the input device during a power supply frame, the second input sensing frame comprises:
• an input sensing period in which the sensor controller is configured to sense the second input through the input sensor;
• and
• a pause period in which the sensor controller is configured to not sense the second input through the input sensor, the power supply frame comprises a power supply period in which the wireless power signal is transmitted to the input device through the wireless power supply at a transmission frequency, and the pause period overlaps the power supply period.
