A pixel structure for OLED display is disclosed. The pixel structure includes multi-row pixel unit groups, each pixel unit group includes a plurality of pixel units arranged repeatedly is sequence, and each pixel unit includes a first sub pixel, a second sub pixel and a third sub pixel, wherein the same sub pixels of the pixel units in adjacent two rows are arranged in dislocation in a horizontal direction. The pixel structure can widen the distance between the corresponding openings of the sub pixels when making the corresponding metal mask to enhance the strength of the metal mask that a pixel unit of a smaller size can be produced under the consideration of process condition, so as to improve the resolution of the OLED display.

Pixel structure for OLED display and metal mask thereof

A pixel structure and an organic light emitting display are disclosed. The pixel structure includes a plurality of pixels which includes a plurality of sub-pixels. At least one pixel forms a pixel unit, and longitudinally adjacent pixel units are arranged in a vertical mirror image, and/or laterally adjacent pixel units are arranged in a horizontal mirror image. The present disclosure may increase the area of mask opening during evaporation, reduce the difficulty of mask production process, and reduce the evaporation process difficulty by a reasonable pixel arrangement structure and allowing sub-pixels of adjacent pixels to share one mask opening to evaporate. It does not need to preset a gap during evaporating the sub-pixels of adjacent pixels of the mask, thereby a real high PPI is achieved while keeping the opening ratio. In addition, the present disclosure can further increase the strength of the mask.
