摘要： An organic light-emitting display device and a method for driving the same are provided. The organic light-emitting display device analyzes input image data in unit of a window mask to detect a halftone data block, adjusts a voltage corresponding to grayscale 0 of center data disposed at the center of the halftone data block to a voltage higher than 0V, and adjusts the voltage corresponding to grayscale 0 in a data block other than the halftone data block to 0V, such that a data voltage swing width at low grayscales can be reduced so as to prevent voltage drop in pixels, thereby improving picture quality.

摘要： Disclosed is a driving method of a display device that includes, for example, setting a luminance increase gain based on a chroma of an RGB data of an input image; modulating the RGB data of the input image based on the luminance increase gain to generate an RGB data of a first image; substituting a W data for common components of the RGB data of the first image and converting the RGB data of the first image to an RGBW data of a second image; and encoding the RGBW data of the second image into an RGBW data of a third image such that a number of bits of the RGBW data of the third image is less than a number of bits of the RGBW data of the second image.
