Display devices and methods of controlling display devices

A method of controlling of a display device, the display device including a display panel in which a display area is defined and including a plurality of pixels and a plurality of sensors, and an input sensing layer on the display panel and configured to sense an external input, the method comprising:

• allowing a first pixel among the plurality of pixels to emit a light, wherein the first pixel is in a first sensing area of the display area, which overlaps the external input;
• sensing, at a first sensor among the plurality of sensors, first biometric information from the external input, wherein the first sensor is in the first sensing area;
• matching the first biometric information with stored first authentication information;
• allowing a second pixel among the plurality of pixels to emit a light, wherein the second pixel is in a second sensing area of the display area, which overlaps the external input and is different from the first sensing area;
• sensing, at a second sensor among the plurality of sensors, second biometric information different from the first biometric information from the external input, wherein the second sensor is in the second sensing area;
• matching the second biometric information with second authentication information different from the stored first authentication information;
• and
• based on the first biometric information matching the first authentication information or the second biometric information matching the second authentication information, driving the display panel.
