Abstract: Provided is an OLED display device that is in a black mode in which a threshold voltage of a driving TFT need not accurately be sensed. Further, a low voltage value of zero or less is constantly and continuously supplied to a data line during an initialization period, a sampling period, and a programming period in a pixel. As a result, when the pixel is driven in the black mode, a reference voltage and a data voltage having different values are not alternately supplied to the data line to minimize power consumption.

Abstract: Discussed are an organic light emitting display which can reduce flicker, along with power consumption, and a driving method thereof. In a low-power operation mode of the organic light emitting display, at least one holding frame is placed between writing frames in which image data is written, the output of the source driver is enabled during the writing frames, the output of the source driver is disabled during the holding frames, and the emission driver is controlled during the holding frames to increase the toggle frequency of the emission signal to be higher than or equal to N times the frame frequency (N is a positive integer greater than or equal to 2). The driving method can reduce the perceived flicker.
