Organic light emitting display device and method of driving the same |
摘要 |
A method of driving an organic light emitting display device includes: dividing one frame into one blank frame and sub-frames; determining whether a data signal to be applied to a pixel circuit of the organic light emitting display device is a data signal of a high gray-level region or a data signal of a low gray-level region based on a predetermined reference gray-level; applying the data signal to the pixel circuit in all of the sub-frames when the data signal is the data signal of the high gray-level region; and applying a first setting data signal corresponding to a gray-level higher than the reference gray-level to the pixel circuit in some of the sub-frames, and applying a second setting data signal corresponding to a zeroth gray-level to the pixel circuit in other sub-frames among the sub-frames when the data signal is the data signal of the low gray-level region. |

1. A method of driving an organic light emitting display device, the method comprising:
dividing one frame into one blank frame and a plurality of sub-frames; determining whether a data signal to be applied to a pixel circuit of the organic light emitting display device is a data signal of a high gray-level region or a data signal of a low gray-level region based on a predetermined reference gray-level; applying the data signal to the pixel circuit in all of the sub-frames when the data signal is the data signal of the high gray-level region; and applying a first setting data signal corresponding to a gray-level higher than the reference gray-level to the pixel circuit in some of the sub-frames, and applying a second setting data signal corresponding to a zeroth gray-level to the pixel circuit in other sub-frames among the sub-frames when the data signal is the data signal of the low gray-level region, wherein the organic light emitting display device implements a gray-level corresponding the data signal by controlling a current flowing through an organic light emitting diode of each pixel circuit thereof based on the data signal, which is an analog driving voltage. |
