A display device according to an embodiment includes a substrate including a plurality of gate lines and a plurality of data lines crossing the plurality of gate lines, and a sub-pixel array structure including a sub-pixel group corresponding to the substrate. The sub-pixel group includes a first sub-pixel, a second sub-pixel in a column different from the first sub-pixel, and third sub-pixels divided in two rows and in two columns with at least one of the first sub-pixel and the second sub-pixel therebetween, wherein the first sub-pixel is in a first column, the second sub-pixel is in a third column, and the third sub-pixels are in second and fourth columns, and wherein a ratio between numbers of the first, second and third sub-pixels is 1:1:4.

Display device having sub-pixel array structure

An organic light emitting diode display device including: a timing controller that receives an image signal and a plurality of timing signals from an external system and output an image data, a gate control signal and a data control signal; a peak luminance controlling unit that calculates a peak luminance according to an average picture level of the image data and calculates a modified peak luminance by modifying the peak luminance according to one or more of a color change and a scene change of the image data; a gate driver that generates a gate signal using the gate control signal; a data driver that generates a data signal using the modified peak luminance, the image data and the data control signal; and a display panel that displays an image using the gate signal and the data signal.
