Abstract: An organic light-emitting display device and a method of driving the same. The organic light-emitting display device is driven, with one frame being divided into a first period, a second period, a third period, and a fourth period, and includes pixels coupled to scan lines and data lines, a first power supply configured to supply first driving power, wherein the first driving power is set to a first voltage during the first period and the fourth period and a second voltage lower than the first voltage during the second period and the third period, a second power supply configured to supply second driving power. The second driving power is set to a third voltage during the first to third periods and to a fourth voltage lower than the third voltage during the fourth period.

Abstract: A display device includes: active stages each include a scan output circuit outputting a scan clock signal to a first output terminal and a carry output circuit outputting a carry clock signal to a second output terminal, when a voltage of a first node is at a logic high level. The scan output circuit and carry output circuit output a scan signal of a turn-off level to the first output terminal when a voltage of a second node or a carry signal is at a logic high level. An interval between pulses of the carry clock signal generated during one frame period is the same, and at least two of intervals between pulses of the scan clock signal generated during the one frame period are different from each other.

Abstract: A liquid crystal display device includes a first row including first, second, and third first-color pixels; a second row including fourth, fifth, and sixth first-color pixels; and a third row including seventh, eighth, and ninth first-color pixels. The first, fourth, and seventh first-color pixels are aligned. The second, fifth, and eighth first-color pixels are aligned. The third, sixth, and ninth first-color pixels are aligned. The second first-color pixel is disposed between the first and third first-color pixels. Each pixel electrode of the first, third, fifth, seventh, and ninth first-color pixels may receive a high voltage for a gray level. Each pixel electrode of the second, fourth, sixth, and eighth first-color pixels may receive a low voltage for a gray level lower than the high voltage for a gray level. Liquid crystal molecules in each pixel have two domain directions.
