  • Patent number: 9343008
    Abstract: An organic light emitting diode (OLED) display includes: a substrate; and a red subpixel, a green subpixel, a blue subpixel, and a white subpixel arranged in a matrix of rows and columns on the substrate, wherein three different-colored subpixels selected from the red subpixel, the green subpixel, the blue subpixel, and the white subpixel form one pixel in which the three different-colored subpixels are simultaneously driven. Four red subpixels in the matrix enclose two green subpixels, two white subpixels, and one blue subpixel. Accordingly, the organic light emitting diode (OLED) display has a RGBW structure, and improves the luminance by the two white subpixels.
