An OLED display including a display panel having a plurality of R, G, and B pixels formed and at least one of a high-potential and low-potential driving voltage supply line disposed; a data driving circuit; a gamma reference voltage generating circuit for generating gamma reference voltages for R, G, and B by dividing voltages of high-potential gamma power sources; a current estimating circuit for generating digital estimated current values for R, G, and B; a current sensing circuit for generating digital sensing current values for R, G, and B; and a gamma power source control circuit for controlling the high-potential gamma power sources by comparing the digital estimated current values for R, G, and B with the digital sensing current values for R, G, and B so that driving currents corresponding to the respective digital estimated current values flow in the respective R, G, and B pixels. |
