Abstract

Disclosed is an electronic device which includes a display layer, a sensor layer above the display layer, and a sensor driver configured to drive the sensor layer in a first mode when a mutual capacitance of a node of the sensor layer compared to a mutual capacitance of another node that is adjacent to the node is outside a ratio range, wherein the sensor layer includes a first electrode including sensing patterns and a bridge pattern, a second electrode including first parts and a second part, and a dummy electrode including dummy patterns, wherein a first area of one of the dummy patterns is less than a second area of one of the first parts, and wherein a ratio of the first area to the second area satisfies the ratio range.
