Abstract
An organic light emitting display device includes: a display panel including a plurality of pixel rows each including first pixel groups alternating with second pixel groups; a gate driver configured to provide a first group gate signal to the first pixel groups, and to provide a second group gate signal to the second pixel groups; a data driver configured to output data voltages to a plurality of output line groups; and a connection controller configured to connect the output line groups to a first data line group in response to a first connection control signal, and to connect the output line groups to a second data line group in response to a second connection control signal.

An organic light emitting display device comprising:
- a display panel including a plurality of pixel rows each including first pixel groups alternating with second pixel groups;
- a gate driver configured to provide a first group gate signal to the first pixel groups, and to provide a second group gate signal to the second pixel groups;
- a data driver configured to output data voltages to a plurality of output line groups;
- and
- a connection controller configured to connect the output line groups to a first data line group in response to a first connection control signal, and to connect the output line groups to a second data line group in response to a second connection control signal,
- wherein an on-period of the second group gate signal partially overlaps an on-period of the first group gate signal,
- wherein the first data line group is connected to the first pixel groups included in the pixel rows,
- wherein the second data line group is connected to the second pixel groups included in the pixel rows, and
- wherein an on-period of the first connection control signal partially overlaps an on-period of the second connection control signal.
An organic light emitting display device comprising:
- a display panel including a first pixel row and a second pixel row adjacent to the first pixel row, the first pixel row including first pixel groups alternating with second pixel groups, and the second pixel row including third pixel groups alternating with fourth pixel groups;
- a gate driver configured to provide a first group gate signal to the first pixel groups, to provide a second group gate signal to the second pixel groups, to provide a third group gate signal to the third pixel groups, and to provide a fourth group gate signal to the fourth pixel groups;
- a data driver configured to output data voltages to a plurality of output line groups;
- and
- a connection controller configured to connect the output line groups to a first data line group in response to a first connection control signal, to connect the output line groups to a second data line group in response to a second connection control signal, to connect the output line groups to a third data line group in response to a third connection control signal, and to connect the output line groups to a fourth data line group in response to a fourth connection control signal,
- wherein an on-period of the second group gate signal partially overlaps an on-period of the first group gate signal,
- wherein the first data line group is connected to the first pixel groups included in the first pixel row, the second data line group is connected to the second pixel groups included in the first pixel row, the third data line group is connected to the third pixel groups included in the second pixel row, and the fourth data line group is connected to the fourth pixel groups included in the second pixel row, and
- wherein an on-period of the first connection control signal partially overlaps an on-period of the second connection control signal.
