Display device with reduced discontinuity of image at boundary between sensor region and display region and method of driving the same

A method of controlling a display device including a substrate, a display panel including a first display region having first pixels, a second display region having second pixels, and a third display region located between the first and second display regions and having third pixels, and a light sensor disposed between the substrate and the display panel to overlap the second display region and not to overlap the first and third display regions, the method comprising:

• receiving image data;
• determining a region on which the image data is to be displayed;
• correcting the image data;
• and
• providing the corrected image data to a corresponding display region,
• wherein the correcting of the image data comprises:
• correcting the image data such that a first group of unit pixel regions of the third display region emits light during a first display period;
• and
• correcting the image data such that a second group of unit pixel regions of the third display region emits light during a second display period subsequent to the first display period,
• wherein the third display region does not have any light sensors, and
• wherein the third display region surrounds an entirety of the second display region, the first and third pixels have the same material and layout,
• the first group of unit pixel regions and the second group of unit pixel regions are arranged to alternate with each other, and
• the first display period and the second display period are alternately repeated.

A display device comprising:

• a substrate;
• a display panel including a first display region having first pixels, a second display region having second pixels, and a third display region located between the first and second display regions and having third pixels;
• and
• a light sensor disposed between the substrate and the display panel and which overlaps the second display region and does not overlap the first and third display regions in a plan view,
• wherein the third display region does not have any light sensors, and
• wherein transmissivity of the second display region is higher than transmissivity of the first display region,
• the transmissivity, a material, and a layout of the first display region is equal to transmissivity, a material, and a layout of the third display region,
• the third display region surrounds an entirety of the second display region,
• the third display region comprises a first group of unit pixel regions and a second group of unit pixel regions arranged to alternate with each other,
• the first group of unit pixel regions is controlled to emit light during a first display period and the second group of unit pixel regions is controlled to emit light during a second display period, and
• the first display period and the second display period are alternately repeated.
