Display device and electronic device including the same

A display device configured to be stretched, and having a display area, and a non-display area outside the display area, the display device comprising:

• conductive lines;
• and
• pixel groups connected to the conductive lines and arranged in a first direction and in a second direction in the display area, each of the pixel groups comprising pixels in a first sub-pixel group and in a second sub-pixel group, and wherein:
• the pixels in the first sub-pixel group and in the second sub-pixel group in each of the pixel groups are configured to emit light or not to emit light such that a number of light-emitting pixels of the pixels increases as a degree of stretching of the display device increases, and
• ones of the pixels in the first sub-pixel group or in the second sub-pixel group in each of the pixel groups are configured to emit light when the display device is in a non-stretched state.

An electronic device comprising:

• a display device comprising pixels in pixel groups repeatedly arranged in a first direction and a second direction in a display area, each of the pixel groups comprising a first sub-pixel group and a second sub-pixel group;
• a sensing unit configured to sense stretching of the display device;
• and
• a processor configured to:
• receive, from the sensing unit, a sensing signal corresponding to the stretching;
• determine a degree of the stretching based on the sensing signal;
• output an image signal corresponding to the degree of the stretching,
• control ones of the pixels of the first sub-pixel group or of the second sub-pixel group to emit light when the display device is in a non-stretched state;
• and
• control the pixels of the first sub-pixel group and of the second sub-pixel group to emit light or not to emit light when the display device is in a stretched state such that a number of light-emitting pixels of the pixels increases as the degree of the stretching increases.
