<p>The present invention relates to an organic light emitting display device and a method for processing image signals thereof. An organic light emitting display device according to the present invention receives a plurality of input image signals respectively corresponding to the pixels representing a first color, a second color, a third color, and a white color, and converts the input image signals of at least two dots respectively representing the first color to the third color among the input image signals according to a first extension coefficient to generate a plurality of four-color image signals of at least two dots respectively representing the first color, the second color, the third color, and the white color, to respectively sum a distortion amount of a color impression of the four-color image signals of at least two dots, to calculate a partial extension coefficient corresponding to the sum result, and to extension-convert the input image signals of at least two dot according to the partial extension coefficient thereby generating the four-color output image signals of at least two dots.</p> |
