Display device and method of operating the same

A method of operating a display device comprising a display panel comprising a display area comprising a plurality of light emitting areas corresponding to a plurality of subpixels, and a non-display area located outside of the display area, a data driving circuit configured to supply a data voltage corresponding to input image data to the display panel, and one or more optical electronic devices including a camera disposed in a first optical area and a luminance sensor disposed in a second optical area that has a degree of transmission that is less than a degree of transmission of the first optical area, the method comprising:

• determining whether the display device operates in a first period in which the display device is not used or a second period proceeded by an input related to screen setting;
• and
• executing an image capturing operation or a sensing operation by the camera during the first period or the second period when a luminance of an environment of the display device sensed by the luminance sensor is less than a threshold luminance,
• wherein the display area comprises one or more optical areas including the first optical area and the second optical area are partially overlapping the one or more optical electronic devices, and a non-optical area located outside of the one or more optical areas,
• wherein the one or more optical areas comprises a plurality of first light emitting areas of the plurality of light emitting areas and a plurality of light transmission areas, and
• the non-optical area comprises a plurality of second light emitting areas of the plurality of light emitting areas, and
• wherein the one or more optical electronic devices overlap at least a portion of the plurality of first light emitting areas in the one or more optical areas,
• wherein the first period is one of a period in which power of the display device is turned off, a period in which the display device is in a lock screen state, or a period in which the display device is in a standby mode state, and the second period is a period proceeded by an input related to screen setting for degradation compensation.

A display device comprising:

• a display panel including a first optical area and a non-optical area that are configured to display an image, the first optical area comprising a first plurality of light emitting areas and a first plurality of light transmission areas and a second optical area having a degree of transmission that is less than a degree of transmission of the first optical area, and the non-optical area including a second plurality of light emitting areas;
• a luminance sensor disposed in the second optical area;
• and
• a camera disposed in the first optical area, the camera configured to perform an image capturing operation or sense light through the first plurality of light transmission areas of the first optical area during one of a first period in which the display device is not used or a second period proceeded by an input related to screen setting when a luminance of an environment of the display device sensed by the luminance sensor is less than a threshold luminance, the camera under the display panel or located at a lower portion of the display panel and overlapping the first optical area but not the non-optical area,
• wherein the first period is one of a period in which power of the display device is turned off, a period in which the display device is in a lock screen state, or a period in which the display device is in a standby mode state, and the second period is a period proceeded by an input related to screen setting for degradation compensation.
