A display device includes: a power supply configured to supply a voltage of first driving power to a first power line, and supply a voltage of second driving power to a second power line; a display panel including pixels connected to scan lines and data lines, and each including a first transistor configured to control current supplied from the first power line to the second power line via a light emitting element; and a timing controller configured to supply a luminance control signal to the pixels. Each of the pixels includes: a control transistor connected in parallel to some sub-transistors of the corresponding first transistor, and configured to be turned on in response to receipt of a luminance control signal having an enabled state. The power supply changes the voltage of the second driving power when the luminance control signal having the enabled state is supplied to the pixels.

Display device and method of driving the same, and electronic device including display device

A display device includes: a substrate; scan lines extending in a first direction, and arranged along a second direction crossing the first direction on the substrate; data lines extending in the second direction, and arranged along the first direction on the substrate; a display area including pixels connected to the scan lines and the data lines; and a non-display area around the display area, and including compensation capacitors connected to some scan lines from among the scan lines. A sum of a capacitance of q odd scan lines or q even scan lines that are adjacent to each other from among the scan lines increases in the second direction, where q is a positive integer.
