Abstract: In a method of operating an organic light emitting display device including a plurality of pixels, an initialization voltage is applied to the plurality of pixels to store the initialization voltage in the plurality of pixels in a first period of an initial period. Driving transistors of the plurality of pixels are concurrently turned on based on the stored initialization voltage in a second period of the initial period, and a plurality of data voltages are sequentially applied to the plurality of pixels on a row-by-row basis to store the plurality of data voltages in the plurality of pixels in a data write period. The plurality of pixels concurrently emit light based on the plurality of data voltages in an emission period.

Abstract: An organic light-emitting diode (OLED) display and method for driving the same are disclosed. In one aspect, the OLED display includes a plurality of pixels and a compensation unit configured to receive first image data including a gray scale value for each pixel. The compensation unit accumulates the first image data to generate accumulated data, selects a data compensation method for each pixel based at least in part on the accumulated data, and compensates the gray scale value included in the first image data for each pixel based at least in part on the selected data compensation method to generate second image data. The OLED display also includes a data driver configured to convert the second image data into data signals and apply the data signals to the pixels.
