Display device having a power providing line
A display device includes: a display panel for displaying frames during an elapse of time; and an emission driver for providing first and second emission power sources to the display panel, wherein: each of the frames comprises a first light emitting period, a light non-emitting period and a second light emitting period according to a time sequence, a difference value between the first and second emission power sources is substantially equal to or greater than a reference value during the first and second light emitting periods, and is less than the reference value during the light non-emitting period, and the difference value between the first and second emission power sources decreases over an elapse of time during the first light emitting period, and increases over an elapse of time during the second light emitting period.
1. A display device comprising:
a display panel comprising a plurality of pixels; and
an emission driver for providing an emission power source to the display panel, wherein:
the display panel comprises first and second sections arranged in a first direction,
at least one pixel of the plurality of pixels is disposed in each of the first and second sections,
the display panel comprises a power providing line for providing the emission power source to the pixels and extended in the first direction, and
the power providing line comprises a first part in the first section, and a second part in the second section having a width different from a width of the first part, wherein the width of the second part in a direction away from the first part is substantially constant along the length of the second section.
2. The display device of claim 1 , wherein the width of the first part is broader than the width of the second part.
3. The display device of claim 2 , wherein:
the display panel further comprises a third section,
the second section is between the first and third sections, and
the power providing line is in the third section and comprises a third part having substantially the same width as the width of the first part.
4. The display device of claim 2 , wherein:
the width of the first part decreases toward an end adjacent to the second part.
