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.
Claims11
An OLED display panel, comprising:
- a substrate;
- and
- a pixel array disposed on the substrate and comprising a plurality of pixels arranged in an orthogonal matrix;
- wherein each of the plurality of pixels comprises a plurality of sub-pixels, and each of the plurality of sub-pixels comprises a driving circuit layer, an uneven layer, and a light-emitting layer stacked in manufacture processing sequence;
- wherein the uneven layer in each of the sub-pixels comprises a plurality of concave-convex structures;
- wherein a number of concave-convex structures monotonically decreases or increases from a center of the pixel array to a periphery of the pixel array in a first direction and/or a second direction, wherein the first direction and the second direction are orthogonal to each other.
