Abstract

An OLED display device is provided. The OLED display device comprises first pixel rows and second pixel rows. A first pixel row includes first and second pixel units, and a second pixel row includes third and fourth pixel units. A first, a second, a third, and a fourth pixel units have an identical hexagonal shape, and each includes a first, a second, a third, and a fourth sub-pixels, each of which has an identical pentagonal shape. The first sub-pixel in the first pixel unit, the second sub-pixel in the second pixel unit adjacent to the first pixel unit, the third sub-pixel unit in the third pixel unit adjacent to both the first pixel unit and the second pixel unit, and the fourth sub-pixel unit in the fourth pixel unit adjacent to both the first pixel unit and the second pixel unit have a same color and together form a hexagon.
