An OLED display, an OLED panel and a driving device are disclosed. Wherein, the OLED display includes the OLED and the driving device. The OLED panel has a plurality of display pixels, every display pixel includes a plurality of sub-pixels, and each of the sub-pixels respectively corresponds to a different color. The driving device includes a plurality of current mirrors for correspondingly receiving one of a plurality of data currents and for generating driving currents sent to the corresponding sub-pixels, respectively. Each the current mirror includes a plurality of transistors and generates a different driving current to drive the corresponding sub-pixels according to the ratios between the channel widths and channel lengths of the transistors in the current mirror.
