Display device, electronic device, and method of driving display device

A display device comprising:

• a display panel including a pixel and a photo sensing pixel;
• a panel driver configured to drive the pixel to emit light;
• and
• a sensor driver configured to operate the photo sensing pixel,
• wherein the sensor driver acquires first sensing data by operating the photo sensing pixel while the pixel emits light, and acquires second sensing data by operating the photo sensing pixel while the pixel does not emit light, and
• wherein the panel driver calculates a compensation value for compensating degradation of the pixel based on the first sensing data and the second sensing data.

An electronic device comprising:

• a processor configured to provide an input image data;
• a display device configured to display an image, based on the input image data;
• and
• a power supply configured to supply power to the display device,
• wherein the display device includes:
• a display panel including a pixel and a photo sensing pixel;
• a panel driver configured to drive the pixel to emit light;
• and
• a sensor driver configured to operate the photo sensing pixel,
• wherein the sensor driver acquires first sensing data by operating the photo sensing pixel while the pixel emits light, and acquires second sensing data by operating the photo sensing pixel while the pixel does not emit light, and
• wherein the panel driver calculates a compensation value for compensating degradation of the pixel based on the first sensing data and the second sensing data.
