1. A display device comprising:
display pixels arranged in a display area of a display panel;
light sensing pixels arranged in the display area;
a display scan driver configured to cause the display pixels to emit light;
a light sensing scan driver configured to cause the light sensing pixels to sense light, and
a main driving circuit configured to measure a user's biometric information by using light sensing signals provided from the light sensing pixels,
wherein the main driving circuit senses the user's touch area when the user's biometric information is measured, and sets a biometric information measurement area and a measurement condition, which includes an emission color and an emission luminance, according to a shape of a sensed touch area and touch area information to measure the user's biometric information,
wherein the main driving circuit selects a reference condition among preset reference conditions to sense the user's touch area when the biometric information is measured, and senses the user's touch area by using the light sensing signals according to the selected reference condition and generates touch coordinate data corresponding to the user's touch area, or controls a touch driving circuit to receive touch coordinate data corresponding to the user's touch area.
