Organic light emitting display panel and method for driving the same

摘要

The present invention provides an organic light-emitting display (OLED) panel and a method for driving the same. The OLED panel comprises pixel rows, data lines, scan lines and power lines, and each of the pixel rows includes pairs of first and second pixels, and the data lines cross the scan lines, and the power lines are arranged parallel to the pixel rows. When driving the first or second pixel, two of the scan lines are turned on at the same time, and the two turned-on scan lines are positioned at two opposite sides of the driven first or second pixel.
