Abstract
A display device includes a display panel. The display panel includes pixels. A sensor layer overlaps the display panel and includes sensors. A sensor driver is configured to transmit a driving signal to the sensors and receive sensing signals from the sensors. The sensor driver is configured to transmit a first driving signal to the sensors to detect a first sensing area where a touch occurs in a first mode, and to transmit a second driving signal to at least a portion of the sensors corresponding to a second sensing area different from the first sensing area in a second mode.

A display device, comprising:
- a display panel comprising pixels;
- a sensor layer overlapping the display panel and comprising sensors;
- and
- a sensor driver configured to transmit a driving signal to the sensors and receive sensing signals from the sensors, wherein:
- in a first mode, the sensor driver is configured to transmit a first driving signal to the sensors to detect a first sensing area where a touch occurs, and,
- in a second mode, the sensor driver is configured to transmit a second driving signal to at least a portion of the sensors corresponding to a second sensing area different from the first sensing area,
- wherein the first driving signal and the second driving signal are different from each other in voltage magnitude.
A method of driving a display device having pixels and sensors overlapping the pixels, the method comprising the steps of:
- transmitting a first driving signal to the sensors through a sensor driver;
- receiving first sensing signals corresponding to the first driving signal from the sensors through the sensor driver;
- transmitting a second driving signal to the sensors through the sensor driver, in response to an object approaching within a first threshold distance;
- and
- receiving second sensing signals corresponding to the second driving signal from the sensors through the sensor driver,
- wherein the first driving signal and the second driving signal are different from each other in voltage magnitude.
