SENSOR-EQUIPPED DISPLAY DEVICE

摘要

According to one embodiment, a sensor-equipped display device includes a display panel, first driver, and second driver. The display panel includes a common electrode, a pixel electrode, a detection electrode, a connection line and lead line. The first driver supplies a common driving signal to the common electrode during a display drive time and supplies a sensor driving signal to the common electrode during a sensing drive time. The second driver detects a sensor output value during the sensing drive time. The lead line and the common electrode are apart from each other with a certain gap at least during the sensing drive time.

主权项

1. A sensor-equipped display device comprising:
a display panel comprising a common electrode and a pixel electrode disposed within a display area to display an image, a detection electrode opposed to the common electrode, a connection line connected to the detection electrode, and a lead line provided within a non-display area outside the display area and electrically connected to the detection electrode via the connection line; a first driver which supplies a common driving signal to the common electrode during a display drive time in which an image is displayed using the pixel electrode and supplies a sensor driving signal to the common electrode during a sensing drive time in which sensing is performed using the detection electrode; and a second driver which is connected to the lead line and detects a sensor output value of the detection electrode output from the lead line during the sensing drive time, wherein the lead line and the common electrode are apart from each other with a certain gap at least during the sensing drive time.
