Abstract
A pixel structure and an organic light-emitting diode (OLED) display panel incorporating the pixel structure are disclosed. Each pixel unit (110) in the pixel structure includes a first sub-pixel (111), a second sub-pixel (112), a third sub-pixel (113) and two fourth sub-pixels (114). The second sub-pixel (112), the third sub-pixel (113) and the fourth sub-pixels (114) are arranged to define a quadrilateral encompassing the first sub-pixel (111) and be common to four adjacent pixel units (110). The first sub-pixel (111) serves as a primary display element, while each of the second sub-pixel (112), the third sub-pixel (113) and the fourth sub-pixels (114) acts as a secondary display element. As a result, a higher aperture ratio of the primary display element can be obtained at the same PPI and design margin, or an increased design margin and reduced process difficulty can be obtained at the same PPI and aperture ratio.
