ABSTRACT:
An OLED display comprising a plurality of pixels, first, second, and third reference voltage generators; and a data driver, all formed on the same substrate is disclosed. Each pixel includes a subpixel of a first color, a subpixel of a second color, and a subpixel of a third color. The first reference voltage generator generates first reference voltages corresponding to a subpixel of the first color, the second reference voltage generator generates second reference voltages corresponding to a subpixel of the second color, the third reference voltage generator generates third reference voltages corresponding to a subpixel of the third color, and the data driver converts digital video signals corresponding to the subpixels of the first, second, and third colors into data voltages, and transmits the data voltages to the subpixels of the first, second, and third colors, respectively.
