PURPOSE: An organic light emitting diode display device and a color coordinate compensating method thereof are provided to improve image quality by compensating a specific deviation of a white color coordinate for each gradation. CONSTITUTION: A color coordinate compensating circuit(14) includes a first gamma converter(141), a data operator(142), a gain controller(143), a data converter(144), and a second gamma converter(145). The first gamma converter receives input data of three colors from a system board. The first gamma converter gamma-converts the input data and supplies the gamma-converted data to the data operator. The data operator extracts a representative value for each pixel based on the gamma-converted data. The data operator determines each representative value to white data of the corresponding pixel and generates a data operation value by subtracting the white data from the gamma-converted data. |
