Abstract

A display device includes a first pixel and a second pixel. The first pixel and the second pixel are defined by a first gate bus line, a second gate bus line, a first power supply line and a second power supply line. A data bus line between the first supply line and the second supply line divides the first pixel from the second pixel line. Accordingly, the pixel shares a data bus line or a power supply line with adjacent pixel. Advantageously, thereby, more space between lines prevents defects caused during fabricating the display device and improve a reliability of the display device.

Claims (21)

1. A display device comprising:

a first gate bus line;

a second gate bus line;

a data bus line;

a first light emitting element operable in response to signals on the first gate bus line, the second gate bus line and the data bus line;

a second light emitting element operable in response to signals on the first gate bus line and the data bus line;

a gate driving section coupled to the first gate bus line and the second gate bus line, the gate driving section being configured to provide a first gate signal to the first gate bus line and a second gate signal to the second gate bus line, wherein the first and second gate signals each have a first period and a second period, and further wherein during the first period, the first gate signal and the second gate signal are applied to the first and the second gate bus lines, respectively; and

a data driving section outputting a first data signal for the first light emitting element during the first period and a second data signal for the second light emitting element during the second period.

2. The display device of claim 1 , wherein the gate signal has a main pulse and a sub-pulse.

3. The display device of claim 2 , wherein during the first period, the main pulse of the first gate signal and the sub-pulse of the second gate signal are applied to the first and the second gate bus line, respectively.

4. The display device of claim 1 , wherein the main pulse has a first and a second main pulse.

5. The display device of claim 4 , wherein the data driving section outputs the first data signal during the first main pulse and the second data signal during the second main pulse.

6. A display device comprising:

a display panel including a first light emitting device electrically coupled to a first gate bus line, a second gate bus line that is adjacent to the first gate bus line, a data line, and a second light emitting device electrically coupled to the first gate bus line and the data line;

a gate driving section configured to apply a first gate signal to the first gate bus line, and a second gate signal to the second gate bus line, wherein the first gate signal includes a first sub pulse having a first time interval and a first main pulse having a second time interval that is longer than the first time interval, the gate driving section being further configured to provide to the second gate bus line a second gate signal including a second sub pulse having the first time interval and a second main pulse having the second time interval, the second main pulse following the second sub pulse, wherein the second sub pulse overlaps the first main pulse; and

a data driving section configured to apply a first data signal to first light emitting device during the first time interval when the second sub pulse overlaps with the first main pulse, and to apply a second data signal to the second light emitting device during a remaining second time interval except for the first time interval.

7. The display device of claim 6 , wherein a rising edge of the second sub pulse is synchronized in time with a rising edge of the first main pulse.

8. The display device of claim 7 , wherein a falling edge of the first main pulse is synchronized in time with a rising edge of the second main pulse.

9. The display device of claim 6 , wherein the first main pulse comprises a first main portion and a second main portion, and further wherein the second main pulse comprises a first main portion and a second main portion.

10. The display device of claim 9 , wherein the rising edge of the first main portion of first main pulse is synchronized in time with a rising edge of the second sub pulse.

11. The display device of claim 10 , wherein a falling edge of the second main portion of the first main pulse is synchronized in time with a rising edge of the first main portion of the second main pulse.
