An organic light emitting display and a driving method for the same are provided to improve image quality by dividing data signals into two groups and supplying them to a data driving unit while using a higher frequency than that of a scan signal. In an organic light emitting display, a plurality of sub pixels are arranged on a display unit(180). A power supply unit(170) supplies first and second power to a first and a second power line connected to the sub-pixel. A scan driving unit(160) supplies a scan signal to a scan line connected to the sub pixel, and a data driving unit supplies a data signal to a data line connected with the sub pixel. A controller(140) supplies a first and a second data signal to a data driving unit, and it applies the first data signal having a higher voltage level than that of the first power source and the second data signal corresponding to a gray scale to the data driving unit. |
