Method for driving the gate lines of a display device to eliminate deterioration

A method for driving a display device comprising a first pixel, a second pixel, a third pixel, a fourth pixel, a first scan line electrically connected to the first pixel, a second scan line electrically connected to the second pixel, a third scan line electrically connected to the third pixel, and a fourth scan line electrically connected to the fourth pixel, the method comprising the steps of:

• supplying a first voltage to the first scan line and a second voltage to the second scan line, the third scan line, and the fourth scan line in a first selection period of a first frame period;
• supplying the first voltage to the second scan line and the second voltage to the third scan line, the fourth scan line, and the first scan line in a second selection period of the first frame period;
• supplying the first voltage to the third scan line and the second voltage to the fourth scan line, the first scan line, and the second scan line in a third selection period of the first frame period;
• supplying the first voltage to the fourth scan line and the second voltage to the first scan line, the second scan line, and the third scan line in a fourth selection period of the first frame period;
• supplying the first voltage to the first scan line and the second voltage to the second scan line, the third scan line, and the fourth scan line in a first selection period of a second frame period;
• supplying the first voltage to the second scan line and the second voltage to the third scan line, the fourth scan line, and the first scan line in a second selection period of the second frame period;
• supplying the first voltage to the third scan line and the second voltage to the fourth scan line, the first scan line, and the second scan line in a third selection period of the second frame period;
• and
• supplying the first voltage to the fourth scan line and the second voltage to the first scan line, the second scan line, and the third scan line in a fourth selection period of the second frame period,
• wherein the first selection period of the first frame period has the same length as the third selection period of the first frame period,
• wherein the second selection period of the first frame period has the same length as the fourth selection period of the first frame period,
• wherein the first selection period of the second frame period has the same length as the third selection period of the second frame period,
• wherein the second selection period of the second frame period has the same length as the fourth selection period of the second frame period,
• wherein the second selection period of the first frame period is longer than the first selection period of the first frame period,
• wherein the first selection period of the first frame period has the same length as the first selection period of the frame period.
