Abstract
An OLED display panel comprises a plurality of concave-convex structures in each sub-pixel, and a light-emitting layer conformal to the concave-convex structure. The number of the concave-convex structures in each pixel varies depending upon the distance from center to peripheral of the OLED display panel, to compensate brightness variations caused by voltage drops and improve white balance of display image.
