  • Patent number: 8183561
    Abstract: A method and device in which the light emitted from a color sub-pixel in an organic light emitted display panel can be the sum of two or more light beams of slightly different colors in the same wavelength range. The difference in color is the result of difference in the length of the resonant cavity within the same color sub-pixel. In the manufacturing process, the non-uniformity in the layer thickness can cause a shift in the color coordinates in the color sub-pixels. The color shift when the width of the color spectrum is narrow is more noticeable. By broadening the width of the color spectrum, the color shift would become less appreciable. Thus, broadening the width of the color spectrum would ease the strict requirements in manufacturing.
