Display device and method of driving the display device

A display device comprising:

• a display region comprising first and second pixel regions, wherein the display device is configured to display an effective image in the first and second pixel regions, corresponding to a first mode, and display an effective image in the second pixel region, corresponding to a second mode;
• a plurality of first pixels and a plurality of first scan lines in the first pixel region;
• a plurality of second pixels and a plurality of second scan lines in the second pixel region;
• a first scan driver comprising a plurality of first scan stages configured to drive at least some of the first scan lines;
• a second scan driver comprising a plurality of second scan stages configured to drive the second scan lines;
• and
• a timing controller configured to supply first and second start signals respectively to the first and second scan drivers,
• wherein, when the display device is driven in the second mode, a width of the second start signal is set wider than a width of the first start signal.

A method for driving a display device, the display device comprising a first pixel region having a plurality of first pixels and a second pixel region having a plurality of second pixels, the method comprising:

• when the display device is driven in a first mode, displaying an effective image in the first and second pixel regions;
• and
• when the display device is driven in a second mode, displaying an effective image in the second pixel region,
• wherein, when the display device is driven in the first mode, a same number of scan signals are supplied to each of the first and second pixels during each frame period,
• wherein, when the display device is driven in the second mode, q (q is a natural number of 2 or more) second scan signals are supplied to each of the second pixels during one frame period, and p (p is a natural number smaller than q) first scan signals are supplied to each of at least some of the first pixels during the period in which the second scan signal is supplied to at least some of the second pixels.
