Abstract

A pixel structure in an organic light emitting display panel includes a plurality of pixels. Each pixel includes a first sub-pixel, a second sub-pixel, and a third sub-pixel. Lengths of the first sub-pixel, the second sub-pixel, and the third sub-pixel are arranged along a first direction. Widths of the first sub-pixel, the second sub-pixel, and the third sub-pixel is arranged along a second direction. A length of the first sub-pixel is greater than a length of the second sub-pixel along the first direction and a length of the third sub-pixel along the first direction. The first sub-pixel, the second sub-pixel, and the third sub-pixel are orderly arranged along the second direction.
