Organic light emitting display device and driving method thereof

摘要

An organic light emitting display device, which can independently (or freely or individually or arbitrarily) control light emission times of red, green and blue subpixels and a driving method thereof. The organic light emitting display device includes a plurality of subpixels connected with scan lines, light emitting control lines, and data lines; a scan driver for driving the scan lines and the light emitting control lines; and a data driver for driving the data lines. Here, the subpixels connected with one of the light emitting control lines generate lights of a same color.
