Pixel arrangement structure and display device

A pixel arrangement structure, comprising:

• a plurality of repeating units arranged in a horizontal, vertical, or oblique direction, wherein each of the repeating units comprises a first sub-pixel, a second sub-pixel, a third sub-pixel, and a fourth sub-pixel which are independent of each other and form a pixel, wherein colors of the first sub-pixel, the second sub-pixel, the third sub-pixel, and the fourth sub-pixel are red, green, blue, and white, respectively;
• wherein center points of the first sub-pixel, the second sub-pixel, the third sub-pixel, and the fourth sub-pixel in a same repeating unit form a quadrilateral;
• wherein a first row of a first repeating unit of the repeating units is adjacent to the first row of a second repeating unit of the repeating units in a row direction, the second sub-pixel and the fourth sub-pixel of the first row of the first repeating unit and the first sub-pixel and the third sub-pixel of the first row of the second repeating unit form a shared pixel, the shared pixel makes an original display of two pixels of the first repeating unit and the second repeating unit become a sensory effect of up to three pixels of the first repeating unit and the second repeating unit, shapes of the first sub-pixel, the second sub-pixel, the third sub-pixel, and the fourth sub-pixel comprise a polygon.
