A four-primary-color organic light emitting display comprises: a display panel (10) where a plurality of first-color pixels, second-color pixels, third-color pixels, and fourth-color pixels are disposed; and a data drive circuit (13) that has a single, digital-to-analog converter (134) to generate first- to fourth-color data voltages and to apply the first-color data voltage to the first-color pixels, the second-color data voltage to the second-color pixels, the third-color data voltage to the third-color pixels, and the fourth-color data voltage to the fourth-color pixels. Herein, the maximum grayscale voltages for the first- to fourth-color data voltages are adjusted to be different on a single gamma graph defined as the input grayscale versus output voltage. |
