One aspect of the invention is a method for playing a stored content providing a plurality of segments which collectively contains the stored content, each segment has using first terminus and a second terminus with the content having a temporal flow from the first terminus to the second terminus. 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. In the second group, a common ejection amount ejection outlet array ejects the same amount of liquid as that of one of the first and second ejection outlet arrays and a non-common ejection amount ejection outlet array ejects an amount of the liquid that differs from that of the first ejection outlet array group.
